However, there are sometimes anomalies in the lane rendering map images, which might mislead human drivers and result in unsafe driving. To accurately and effectively detect the anomalies, this paper transforms lane rendering image anomaly detection into a classification problem and proposes a four-phase pipeline consisting of data pre-processing, self-supervised pre-training with the masked image modeling (MiM) method, customized fine-tuning using cross-entropy loss with label smoothing, and post-processing to tackle it using state-of-the-art deep learning techniques, especially the Transformer models. Various experiments verify the effectiveness of the proposed pipeline. The proposed pipeline can deliver superior lane rendering image anomaly detection performance, and especially, the self-supervised pre-training with MiM can greatly improve the detection accuracy while significantly reducing the total training time, e.g, Swin Transformer with Uniform Masking as self-supervised pretraining (Swin-Trans-UM) obtained better accuracy at 94.77% and better Area Under The Curve (AUC) at 0.9743 compared with the pure Swin Transformer without pre-training (Swin-Trans) whose accuracy is 94.01% AUC is 0.9498, and the fine-tuning epochs reduced to 41 from original 280. Ablation study further regarding techniques to alleviate the data imbalance between normal and abnormal instances further enhances the model performance.","Anomaly Detection; Lane rendering image; Transformer; Self-supervised learning; Image classification","en","poster","","","","","","","","","","","Transport and Planning","","",""

Thus, social-aware motion planning and control while considering interactions with HDVs on the road is critical for AVs’ deployment and safe driving under various maneuvers. Previous research mostly focuses on the trajectory planning of AVs using Model Predictive Control or other relevant methods, while seldom considering the integrated planning and control of AVs altogether to simplify the whole pipeline architecture. Furthermore, there are very limited studies on social-aware driving that makes AVs understandable and expected by human drivers, and none when it comes to the challenging maneuver of driving through roundabouts. To fill these research gaps, this paper develops an integrated social-aware planning and control algorithm for AVs’ driving through roundabouts based on Driving Risk Field (DRF), Social Value Orientation (SVO), and Model Predictive Contouring Control (MPCC), i.e., DRF-SVO-MPCC. The proposed method is tested and verified with simulation on the open-sourced highway-env platform. Compared with the baseline method using purely Nonlinear Model Predictive Control, the DRF-SVO-MPCC can achieve better performance under various maneuvers of driving through roundabouts with and without surrounding HDVs.","Automated vehicles; Planning and control; Social-aware driving; Roundabouts; Driving Risk Field; Model Predictive Contouring Control","en","poster","","","","","","","","","","","Transport and Planning","","",""

Therefore, a study of the acoustic emission method associated with visual fracture evaluation was proposed to give insights into the toughening of composite bonded joints and better understand the relationship between the acoustic emission features and the damage mechanism involved. Thus, two different layups were proposed for the substrates: [0]8 and [0/902/0]S. In addition, a toughened epoxy adhesive with an embedded carrier (AF163-2k) was used to bond the substrates. Five specimens of each stacking sequence were tested under quasi-static mode I loading conditions. A travelling microscope and a regular digital camera were used on the lateral sides of the specimens to track the crack propagation paths. One piezoelectric sensor linked to the AMSY-6 Vallen system was used to assess the acoustic emission features produced within the joints during the tests. Unsupervised machine learning algorithms based on artificial neural networks and the Morlet continuous wavelet transformation were used to pattern recognition of the acoustic emission data. Self-organising maps, together with k-means algorithms, were used for data clustering. Following that, the acoustic emission features of each cluster were associated with the insights obtained from the crack propagation images. Finally, it was observed that the different layups triggered simultaneous toughening mechanisms.

However, current lane detection methods can not deliver the versatility of accurate, robust, and realtime compatible lane detection in real-world scenarios especially under challenging driving scenes. Available vision-based methods in the literature do not consider critical regions of the image and their spatial-temporal salience regarding the detection results, thus they deliver poor performance in peculiar difficult circumstances (e.g., serious occlusion, dazzle lighting). This study aims to introduce a novel sequential neural network model with a spatial-temporal attention mechanism that can focus on key features of lane lines and exploit salient spatial-temporal correlations among continuous image frames for the purpose of enhancing the accuracy and robustness of lane detection. Under the regular encoder-decoder structure and with the implementation using common neural network backbones, the proposed model is trained and evaluated on three large-scale opensource datasets.

Available vision-based lane detection methods do not make full use of the valuable features and aggregate contextual information, especially
the interrelationships between lane lines and other regions of the images in continuous frames. To fill this research gap and upgrade lane detection performance, this paper proposes a pipeline consisting of self pre-training with masked sequential autoencoders and fine-tuning with customized PolyLoss for the end-to-end neural network models using multi-continuous image frames. The masked sequential autoencoders are adopted to pretrain the neural network models with reconstructing the missing pixels from a random masked image as the objective. Then, in the fine-tuning segmentation phase where lane detection segmentation is performed, the continuous image frames are served as the inputs, and the pre-trained model weights are transferred and further updated using the backpropagation mechanism with
customized PolyLoss calculating the weighted errors between the output lane detection results and the labeled ground truth. Extensive experiment results demonstrate that, with the proposed pipeline, the lane detection model performance on both normal and challenging scenes can be advanced beyond the state-of-the art results, while the training time can be substantially shortened.","","en","poster","","","","","","","","","","","Transport and Planning","","",""

(TU Delft Transport and Planning)","","2023","The platform carrying capacity of urban rail transit stations is limited and overcrowding of the platform will lead to serious safety risks for passengers and trains. It is significant to collaborate on the optimization of passenger flow strategy and skip-stopping scheme to alleviate traffic pressure and ensure platform safety. This study proposes and solves the joint optimization problem of coordinated flow control and skip-stopping scheme considering platform carrying capacity. Firstly, platform demand constraints and platform stranded constraints are designed according to the maximum carrying capacity of the platform to control the number of allowable arrivals ensuring platform safety. Secondly, train arrival variable and train stop variable are introduced to generate train skip-stopping index. Finally, considering the characteristics of passengers' continuous arrival and platform carrying capacity, a mixed integer programming model is established to minimize the number of passengers outside the station and the number of passengers stranded on the platform. Based on empirical data, this study takes Beijing Batong line as a case study and uses the established model to generate flow control strategy and skip-stopping schemes for each station during morning rush hours. Experimental results show that compared to the baseline without implementing the two proposed strategies, the proposed collaborative optimization method can effectively reduce the demand for staying at the platform and increase the number of boarding passengers at downstream stations. Thus, the balance between train capacity and passenger flow demand is maintained while ensuring platform safety. Moreover, the proposed method can also avoid overcrowding at downstream stations.","urban rail transit; coordinated passenger flow control; mixed integer programming; skip-stopping scheme; station platform capacity","en","poster","","","","","","","","","","","Transport and Planning","","",""

(TU Delft Transport and Planning)","","2023","Traffic microsimulation is a commonly used tool in traffic engineering. Given its flexibility and cost-efficiency, it is increasingly used for evaluating traffic safety. In real life traffic, unsafety is in many cases due to human error in driving behaviour. In traffic microsimulations however, driving behaviour is highly dependent on the formulated driving behavioural models and the level of their realism. Most of these behavioural models were developed ignoring the inconsistencies and error proneness of human behaviour. A quantitative evaluation of the differences in the safety level between real life and simulated traffic, considering the mathematical formulation of different driver behavioural models, is lacking in the literature. The main aim of this study is to investigate the influence of different behavioural models’ formulations on the correlation between simulated and empirical surrogate safety measures’ outcomes. For this purpose, high-quality empirical trajectory data were used to calibrate and validate different driver behavioural models. SUMO (Simulation of Urban MObility), an open-source traffic microsimulation software, was used as a platform for calibrating, validating, and testing four distinct combinations of car following and lane changing models. The results show that, regardless of the behavioural model formulations used, the number of simulated traffic conflicts is overestimated. This is most likely due to a higher frequency of lane changes and an unrealistic distribution of traffic over the different lanes in microscopic traffic simulation. The severity of the simulated conflicts was shown to be reasonably accurate at an aggregate level but not significantly comparable at a microscopic level.","","en","poster","","","","","","","","","","","Transport and Planning","","",""

However, the opportunity for private persons to act as occasional carrier can also generate new trips, which could then increase traffic volumes. Previous literature has focused on the consolidation case only, and has not addressed new activity generation in crowdshipping. In this study we investigate the willingness of private persons to accept shipments based on a newly generated home-based trip and compare this to choices of occasional carriers who had already planned their travel, in this case related to the daily commute. We conduct two stated preference experiments and apply a multinomial logit model to identify preferences. Additionally, a latent class choice model is utilized to explore the existence and effect of heterogeneity in preferences. The results show that commute-based and home-based trips have
different VoT parameters and the former is higher than the latter. Parcel lockers as delivery points have a positive effect on acceptance since they allow for more flexibility in delivery times. The latent class model suggests that the distinction between low income and high-income groups is relevant; here, the low-income group has a lower value of time and is more willing to make a detour to execute the delivery. The study provides first quantitative evidence that crowdshipping can act as a potential trip generator in households and recommends that this is taken into account in passenger transportation models.","","en","poster","","","","","","","","","","","Transport and Planning","","",""

three PhD research projects that was created within the collaboration between the
Royal Schiphol Group and the Industrial Design Engineering faculty of the TU Delft.
With this collaboration, researchers from the IDE faculty were engaged in three challenges: (1) designing towards pandemic antifragility in Multimodal Transport Hubs (MTHs); (2) transforming Airport Hubs into passenger-oriented MTHs, and (3) investigating the adoption of autonomous processes in the context of organizations. An action research methodology is followed in the projects, meaning that the researchers are embedded in the organization, and actively participate in daily
practice. This poster presents the scope of the three projects, as well as the studies and academic supervision tasks that the researchers have undertaken until now; we hope to contribute with an example of action-research oriented PhD projects, which could serve to ilustrate transdisciplinary research perspectives.
In terms of motivations, our study reveals that the location and immediate surrounding is decisive for real estate companies’ willingness to extra invest in public space, as these investments do not pay off as much everywhere and are conditioned by the financial viability of urban regeneration project itself. Additionally, real estate companies indicate that ESG business objectives are increasingly important in investment decisions, with public space functioning as potential tangible means and proof. In terms of conditions, real estate developers and investors indicate that control over assigning rights, distributing responsibilities and shaping characteristics of the investment in public space is decisive. They want to be able control how extra investments are spent to ensure that their own company vision and the development concept for the project is realised to a sufficient degree. The biggest challenge in making public-private agreements about the extra investments are local authority public space standardisation regulations that hinder customization. Additionally, the lack of proven private management instruments for the use phase currently directs Dutch developers and investors to full legal ownership of public space as the only (limited) solution.
Based on the above empirical findings, this research illustrates that it is not possible to determine an ‘ideal framework’ for the distribution of roles and responsibilities for private public space investment and subsequently the management thereof, as public space is non-generic in nature. Nevertheless this research indicates possible conditions under which real estate companies are willing and able to extra invest in public space, thereby seeking collaborations with the public sector and establishing attractive public spaces to the potential benefit of both organisations and users alike. Scientifically, our study adds new insights about the importance of private sector investment considerations into public-private agreements besides those that safeguard the publicness of urban spaces. Research limitations include the external validity (generalisability) of the findings beyond the Dutch institutional real estate practice, and the internal validity due to the limited triangulation and qualitative nature of methods used.","urban regeneration; real estate investment; public space; management","en","poster","","","","","","","","","","","Urban Development Management","","",""

With the advancement of machine learning (ML) algorithms and the accumulation of naturalistic driving data, many ML models have been adopted for abnormal driving behavior detection. Most existing ML-based detectors rely on (fully) supervised ML methods, which require substantial labeled data. However, ground truth labels are not always available in the real world, and labeling large amounts of data is tedious. Thus, there is a need to explore unsupervised or semi-supervised methods to make the anomaly detection process more feasible and efficient. To fill this research gap, this study analyzes large-scale real-world data revealing several abnormal driving behaviors (e.g., sudden acceleration, rapid lane-changing) and develops a Hierarchical Extreme Learning Machines (HELM) based semi-supervised ML method using partly labeled data to accurately detect the identified abnormal driving behaviors. Moreover, previous ML-based approaches predominantly utilize basic vehicle motion features (such as velocity and acceleration) to label and detect abnormal driving behaviors, while this study seeks to introduce Surrogate Safety Measures (SSMs) as the input features for ML models to improve the detection performance. Results from extensive experiments demonstrate the effectiveness of the proposed semi-supervised ML model with the introduced SSMs serving as important features. The proposed semi-supervised ML method outperforms other baseline semi-supervised or unsupervised methods regarding various metrics, e.g., delivering the best accuracy at 99.58% and the best F-1 measure at 0.9913. The ablation study further highlights the significance of SSMs for advancing detection performance.","Abnormal driving behavior; Semi-supervised machine learning; Hierarchical extreme learning machines; Self-supervised training; Surrogate safety measure","en","poster","","","","","","","","","","","Transport and Planning","","",""

Transitioning from initial markets to mergers, acquisitions, IPOs, SPACs, or buyouts, startups face the dual potential for immense success or failure, a hallmark of the high-risk startup ecosystem. The construction industry, especially in the realm of technology startups like SaaS, is witnessing this trend. Unlike software-centric firms, construction robotics startups grapple with challenges posed by the need for physical, custom products, demand volatility, and lengthy development cycles. Venture capital funding is crucial for these 'deep tech' ventures. Still, it introduces the principal-agent issue, where aligning the entrepreneur's actions with the VC's interests is complicated by information asymmetry. VCs counter this through high-powered incentives, controlling rights, and staged investments. Despite the critical nature of this topic, academic research on VC impacts on hardware startups in the architecture, engineering, and construction (AEC) sector is sparse. Our research aims to fill this gap. We conducted 127 semi-structured and open-ended interviews with 95 individuals across Europe, North America, and other regions in 2022 and 2023. The resulting data, comprising over 90 hours of interviews and field notes, was analyzed using abductive thematic analysis, categorizing 2998 data segments into nine categories within three major themes. This analysis revealed five dimensions of VC's influence on construction robotics startups, highlighting misalignments and dynamic interactions. In preparation for journal publication, this research complements a parallel, data-centric quantitative study, enriching our understanding of this complex subject.

Enforced lockdowns for limiting the spread of Covid-19 virus also substantially reduce air pollutant emissions from vehicle traffic, industrial plants, etc. The lockdown restrictions have brought beneficial environmental implications, such as improvement of air quality. Previous studies recorded the reduction of air pollutants during the short-term lockdown in some cities and areas in Indian, China, and the U.S. [1-5]. While some studies argue that the improvement of air quality is not due to lockdown, but season influence or temporary change by coincidence [6]. Therefore, there is not enough evidence that the improvement of air quality is mainly due to reduced human activities. It is beneficial to answer this question by investigating and comparing the air pollution changes within countries with multi waves of pandemic timelines and different lockdown measures.
Our research chose Germany and the Netherlands to investigate the air pollutant changes during their multiple lockdowns. Both of the two countries have gone through several pandemic waves while their imposed strategies are different, ranging from lockdown light, partial lockdown, full lockdown, to curfew in different stages of the pandemic. Our research investigates changes in air quality during their multiple pandemic waves and compares seasonal and monthly changes with the historical records (pre-pandemic) from ground stations to analyze the anomalies. During the pandemic period, the research will compare the disparities of air quality improvement with the several pandemic waves among mega urban agglomerations within the two countries. For the pre-pandemic period, this research analyzes the anomaly in comparison with the historical records with the air quality index.
In particular, we adopt the datasets produced by a space-borne air pollution sensor TROPOMI on the Sentinel-5P satellite, provided in Google Earth Engine data catalog. We process the data and extract information about air pollution, including CO, NO2, SO2, O3, and CH4 for analyzing the air pollutant composition changes during the several pandemic waves. First, the decline values of air pollutant composition will be calculated and analyzed between the pandemic waves to prove the different changes following every wave in main urban areas within the two countries. Second, by aggregating the air pollutant concentrations from the satellite-based air pollution data into monthly, seasonal, and annual data and comparing them with corresponding historical records from ground stations at the same periods of pre-pandemic time, the anomalies will be calculated and analyzed to illustrate the improvement of air quality because of pandemic lockdowns at the country level. The historical record data will be collected from the air quality index based on the ground station measurements. Third, the disparities of air pollutant reduction during the pandemic will be also analyzed between the Netherlands and Germany, considering their different lockdown strategies.
The result will provide strong evidence on the air quality improvement due to the reduction of human activities during lockdown periods and highlight the influence of anthropogenic activities on air pollution. The resulting information will provide information to policymakers concerning emission control and sustainable urban development.

However, under certain challenging peculiar circumstances (e.g., marking degradation, serious vehicle occlusion), it is quite difficult to get satisfactory performance in accurately detecting the lane markings from one single image which is often the case in current literature. Since road markings are continuous lines on the road, the lanes that are difficult to be accurately detected in the current image frame might potentially be better inferred out by incorporating information from previous frames. To tackle the challenging scenes, we propose a novel hybrid spatial-temporal sequence-to-one deep learning architecture making full use of the spatial-temporal information in multiple frames of a continuous sequence of images for detecting lane markings in the very last current image frame. Specifically, the hybrid model integrates the spatial convolutional neural network (SCNN), which is powerful in extracting spatial features and relationships in one single image, with convolutional long-short term memory (ConvLSTM) neural network, which can capture the (spatial-)temporal correlations and time dependencies between the image sequences. In this way, the advantages of both SCNN and ConvLSTM are fully combined and the spatial-temporal information is fully exploited. Treating lane detection as the image segmentation problem, we applied encoder-decoder structures to make it work in an end-to-end way. Extensive experiments on two large-scale datasets reveal that our proposed model with the corresponding training strategy can effectively handle challenging driving scenes and outperforms previous methods.","Lane Detection; Convolutional neural network (CNN); Long Short Term Memory Neural Network; Deep Learning; spatial–temporal","en","poster","","","","","","","","","","","Transport and Planning","","",""

Overview and motivation
The emergence of e-commerce in the past decade and the surging growth during the pandemic, partially at the cost of in-store shopping, have reinforced the need for a better representation of this type of consumer demand and its effects in urban transportation studies (Reiffer et al, 2021). Since this is a recent development, conventional passenger transport models only model the personal mobility for in-store shopping. Standard modelling tools for large-scale demand forecasts for online and in-store shopping are limited. A proper representation of this demand segment first of all requires an estimate of e-commerce demand, and second the simulation of the delivery of the orders. Jaller and Pahwa (2020) developed both an econometric MNL model for in-store and online shopping and applied it to a synthetic population to estimate externalities of the alternatives. The econometric model explains the preferences for type of shopping but not the total level of product consumption, and the delivery of online orders is estimated on aggregate statistics. Other disaggregate simulation studies only focus on e-commerce demand, without considering the trade-off between online versus in-store shopping, such as Cheng et al (2021). In effect, online ordering may reduce physical movements of people to stores, while increasing the delivery of orders to people’s home addresses. This shift is taking place for many consumer products and groceries as well. Weltevreden and Rotem-Minaldi (2007) show early evidence that e-commerce ordering in the Netherlands increases freight transport, while personal travel decreases marginally. On the side of e-commerce deliveries, the simulation of urban freight transport is a well-studied topic in recent literature (Mommens et al, 2021; Hörl and Puchinger, 2021; Reiffer et al, 2021). However, modelling the demand side of e-commerce is often still minimal.
2. Methodology, results and main contributions
We present an empirical e-commerce demand model that is implemented in an urban freight simulator developed in the H2020 project HARMONY (Kamargianni et al, 2020). This new demand model for e-commerce is now a part of the simulator’s parcel module, which generates delivery tours based on the parcel demand by households and businesses. We estimated an ordered logit model with the demand for e-commerce shipments to households as the dependent variable, based on the assumption that one online order equals one parcel, as a function of personal and household characteristics which are known within the simulator.
A second model, connecting e-commerce with the demand for traditional in-store shopping, is also presented here, albeit not yet implemented in the urban freight simulator. In this model we first estimated total consumer demand separately for groceries and non-groceries, and next an adoption model for e-commerce services. The model has the structure of a two-step logit model: an ordered logit model for the total consumer demand, and next a binary choice model for the choice between online and in-store shopping for each of the shopping occurrences that make up a person’s consumer demand.
The models are estimated on the Mobility Panel Netherlands, the MPN (Hoogendoorn-Lanser et al, 2015). The 2017 wave of the MPN contained additional questions regarding online and in-store shopping that can be used for the estimation of choice models. To make the models suitable for application in the freight simulator, we focused on explanatory variables that differ between locations (i.e., zones in a model). The most important variables in the choice models that explain the spatial pattern of e-commerce demand are household income, age of the respondent (in 10 categories) and urbanization level at household location. Other personal characteristics that do not vary spatially are included if they improve the explanatory power of the models (e.g., gender).
3. Conclusion and future works
Age and household income are important predictors for the adoption of e-commerce and the number of parcels ordered. The age-classes 18-39 have the highest preference for e-commerce ordering. Above 40, the preference for e-commerce steadily declines. Persons living in households in the highest income classes (more than 67,000€ per year) are the most likely adopters of online ordering for both groceries and non-groceries. The urbanization level does not affect the adoption of e-commerce services for non-groceries, but strongly for groceries. This can be explained by the limited availability of e-groceries in less urbanized areas, especially at the time of data collection in 2017.
The presented e-commerce demand model has been implemented in the HARMONY Tactical Freight Simulator where it is used to calculate the number of parcels delivered in an area, the subsequent delivery tours and their effects on traffic and emissions. As the explanatory variables differ between zones, we obtain spatially distinct effects. In a next step, the presented model can be linked to a passenger simulator to jointly model and assess the generation of shopping trips and parcel deliveries. Another important research topic is the formulation of representative growth scenarios for e-commerce demand. As online ordering adoption rates evolve over the coming decade, socio-economic developments alone will likely not be sufficient to explain them. Adequately representing the evolution of these adoption rates in transport models requires a tailored calibration approach.
E-commerce is a rapidly developing segment within urban goods transportation. While currently making up only 5.5% of all kilometers driven by vans in the Netherlands (CBS, 2018), this segment is experiencing rapid growth. For example, in the Netherlands, the volume of parcel deliveries grew by 20% in 2018 (ACM, 2018). This growth is further accelerated by the current coronavirus pandemic. The increasing importance of this segment is not reflected yet in strategic models used in practice for transportation demand forecasting. Parcel deliveries are not modelled explicitly, which does not only prevent the model users from calculating effects of scenarios and policies related to e-commerce, but it also disregards the unique nature of this segment (e.g. specific depot locations, strong growth rates) and, therefore, leads to flawed reference forecasts of van traffic.
In the scientific literature there are some first examples of simulation models for parcel deliveries (Sakai et al, 2020; Hörl & Puchinger, 2021; Llorca & Moeckel, 2021; Mommens et al., 2021; Reiffer et al., 2021). However, each of these examples lacks an empirical disaggregate demand model, focusses on one (part of a) city rather than a whole region, or focusses on one product/service segment rather than all parcel deliveries in a region. Moreover, little experience is gathered in applying such urban freight simulators for traffic forecasting.
2. Methodology, results and main contributions
To combat these shortcomings of the state-of-practice freight models, we developed a module for last-mile parcel deliveries and used it to explore the impacts of different scenario assumptions regarding parcel demand and scheduling. The module consists of two sub-modules: the parcel demand sub-module and the parcel scheduling sub-module.
The parcel demand sub-module calculates parcel demand based on the households and businesses in each zone. For parcels to households (B2C), a logit model is estimated on the Mobility Panel Netherlands, which included several questions regarding parcel orders in 2017 (Hoogendoorn-Lanser et al., 2015). For parcels to businesses (B2B) an average factor is deduced from aggregate statistics reported by ACM (2018). Once the total number of parcels is determined, they are spread over the different courier companies, based on their respective market shares in terms of number of parcels. Finally, for each zone and courier, the nearest depot is determined; from this depot the parcels will be shipped to their end destinations.
The parcel scheduling sub-module forms round-tours to deliver all the parcels for each parcel courier in the study area. From each depot, simple heuristics (such as nearest-neighbor and 2-opt) are used to form efficient tours that respect the vehicle capacity (in terms of number of parcels) and maximum shift lengths for drivers. This, in turn, leads to trip matrices that can be assigned to the network to arrive at network statistics such as vehicle kilometers and emissions.
The conceptual architecture of this module has been applied in four modelling systems:
(1) the strategic freight model of Flanders (SVRM);
(2) the travel demand model of the Municipality of Amsterdam (VMA);
(3) the module for logistical decision-making of the national strategic freight model of the Netherlands (BasGoed);
(4) and the tactical freight simulator of the HARMONY project for the European Commission (test bed: Province of Zuid-Holland, the Netherlands).
In this research we will analyze the impacts of different scenarios and policies, for this purpose we will use the HARMONY implementation of the model in Zuid-Holland. The scenarios explore the impacts of different developments for:
• increased demand for parcels;
• horizontal collaboration between couriers, with shared use of depots;
• a zero-emission zone in Rotterdam, in combination with consolidation centers at the outskirts of the city.
3. Conclusion and future works
A disaggregate region-wide simulation model for parcel deliveries is necessary to evaluate the impacts of policies and developments in e-commerce. Using the developed model, we can show, for example, that vehicle kilometers do not increase linearly with parcel demand due to increased consolidation and that the impacts of zero-emission zones can be diffuse due to rerouting of van trips.
Future efforts may focus on modelling the whole transport chain of e-commerce, rather than only the last-mile deliveries. Furthermore, a demand model for parcels to businesses in line with the model for households is desired, this would require additional data collection.
Statistical analysis of presented measures, and the computation of an overall composite score revealed a preference towards traditional and familiar traffic elements.","online study; vehicle; automated; vulnerable road users; Augmented Reality; pedestrians; interaction","en","poster","","","","","","","","","","","Human-Robot Interaction","","",""

The rationale for this is based on the new CryoSat-2 scientific roadmap, which specifically addresses the key technical and scientific challenges related to the long-term monitoring of sea-level and ocean circulation changes in the context of Global Warming. This also involves opportunities for synergy with missions like ICESAT-2 and the upcoming Copernicus CRISTAL mission.
In this context, the objective of our research is the long-term monitoring of the level-2 CryoSat-2 Geophysical Ocean Product (GOP), by evaluating the stability of the measurement system and identifying potential biases, trends and drifts over the ocean, through calibration and comparisons with concurrent ocean altimeter data, supported by the Radar Altimeter Database System (RADS). Independently, we also address this by comparing the GOP geophysical parameters with external models and in situ measurements such as the ones from selected sets of tide gauges. The very precise determination of the orbital height is part of the research activity but dealt with in a separate paper.
For our activity we persistently monitor, analyze and identify systematic errors in the observations, estimated (trends in) biases in range, significant wave height, backscatter, wind speed and sea state bias, and timing biases. An important finding is that GOP CryoSat-2 Baseline C data seem to have a range bias of -2.82 cm and no apparent drift w.r.t. altimeter (Jason) reference missions (< 0.1 mm/yr). The comparison with tide gauges is based on monthly averaged sea level from the PSMSL archive, for which we conclude that GOP data has a correlation of better than 0.84 with a selected set of 185 PSMSL tide gauges, a mean standard deviation better than 5.8 cm, and an average drift of -0.19 mm/yr, which translates to an overall drift of +0.11 mm/yr when taking a global GIA correction of +0.3 mm/yr into account. We conclude that Cryosat-2 GOP represents a (long-term) stable measurement.","","en","poster","","","","","","","","","","","Astrodynamics & Space Missions","","",""

(TU Delft Physical and Space Geodesy)","","2022","Satellite observations can help in the retrieval of constituents in shallow waters. Noise contamination, however, makes smaller constituents irretrievable and large sources of error. Throughout shallow areas, the constituent’s relevancy changes. For example, near an amphidromic point where M2 relevance drops, so does the potential of satellite contribution for improving its accuracy. Moreover, shallow waters are generally influenced by many constituents (>100). Accurately retrieving all these constituents with satellite radar altimeter data alone is not possible. Series length requirements imposed by the Rayleigh criteria to separate constituents are still unavailable.
Removing unwanted signals from satellite observations improves least-squares-based harmonic estimates, given an inversion matrix with the same condition number. This variance reduction is the core of the remove compute restore approach commonly used. First, residual harmonic sets are computed with the difference between observations and model background estimates through conventional or weighted least-squares. Then, the residual harmonics are added to the background model estimates.
Here we implemented a method that extends the typical approach by including model background estimate and error covariance in the least-squares step. This inclusion helps to weigh between constituents well represented in the model and those that must be updated.
To test the method, we designed a semi-synthetic experiment. First, we used tide gauge data to generate a satellite equivalent dataset and compared estimations between the two methods listed above and the model estimate. Next, we applied the method to compute tidal estimates along satellite radar altimeter tracks (T/P Jason) in the 2D Dutch Coastal Shelf Model (DCSMv6) domain.
Results from the synthetic experiment show that the second method produces consistently better estimates reducing RSS consistently through temporal cross-validation. In addition, it provides an effective way of keeping as many constituents estimates as the model series can resolve, adding the benefits of satellite observations. Finally, results from the North Sea implementation show the new estimates increase the variance reduction of satellite residuals across the whole domain relative to background tidal estimates. The range of improvements varies between 0 and 3cm, which is significant given already very accurate model background estimates. The benefited areas include the English Channel, the Irish Sea, the English North-Sea Coast, the Bay of Biscay, the German Bight, and the North Atlantic region close to the upper boundary of the model domain.","","en","poster","","","","","","","","","","","Mathematical Physics","","",""

Much of what we know about convective momentum transport stems from high-resolution simulations because high-resolution measurements of the wind profile are rare. This study exploits ground-based remote sensing techniques to visualize wind below and within clouds and their surroundings, to assess momentum transport. The Tracing Convective Momentum Transport in Complex Cloudy Atmospheres experiment (CMTRACE) took place at the experimental Cabauw site (The Netherlands) between 13.09.2021 and 03.10.2021. The goal of CMTRACE was to provide continuous profiles of horizontal and vertical wind with a temporal resolution of ~1 minute and vertical resolution of ~50 m within the cloud and sub-cloud layers to improve our understanding of the role of momentum transport from cloud- to mesoscales. A scanning wind lidar provided the observations in the sub-cloud layer, while in the cloud layer, one scanning and one vertically pointing cloud radar provided observations. During CMTRACE, we sampled various cloud regimes including non-precipitating shallow cumulus clouds, deep convective clouds and stratiform clouds. In this study, we illustrate some of the most interesting CMTRACE observations that reveal the circulations (winds) near clouds and present statistical analyses as a function of different cloud regimes. Specifically, we calculate profiles of wind fluctuations and their cross-correlations to address the momentum flux carried on cloud- and mesoscale scales. The observations from different cloud regimes (e.g. clear sky, shallow convection and frontal passage) are compared to momentum fluxes and wind variability in the Dutch Large-Eddy Simulations nested on the experimental site for the selected days.","","en","poster","","","","","","","","","","","Atmospheric Remote Sensing","","",""

This research focuses on urban design for the redevelopment of Old Major Railway Stations in Megacities in China.
Problems & Goals: From our focused cases, two problems are discovered: Stuckness and congestion on peak days, Space underuse on normal days. Two goals are proposed correspondingly: Mobility Resilience and Public Space Flexibility.
Knowledge Gaps: Theoretical and practical knowledge are lacking for the proposed goals. The component words of the goals all have rich meanings. Some of them have related assessment tools and design recommendations.

The Assessment Frameworks offer researchers a new tool to assess the Station City problems through different dimensions. It can also be used for evaluations during the iterative design process. The Design Principles can be used for the scheme establishment.
Methods: For Concept Definitions, papers about mobility, resilience, public space, and flexibility were examined to propose definitions. For Assessment Framework, available technologies & data will be tested. For Design Principles, case studies of the best practices will be conducted.
Relevance: Scientifically, the Problem Identifications show a creative way of framing research problems between specification and generalization. These Concept Definitions show a solid way of transferring knowledge from other disciplines to urban design fields. Societally, the Problems Identifications and Concept Definitions set a starting point for practitioners to take action.

Exposure to air pollution is highly related to a range of diseases including respiratory and cardiovascular diseases, such as lung cancers, asthma, diabetes, irregular heartbeat, stroke and obesity [1-3]. The outbreak of the pathogenic agent of coronavirus disease 19 (Covid-19) has led to a large number of deaths worldwide, and previous studies have pointed out how the long-term exposure to air pollution may have an impact on its high death rate [4]. Moreover, the hospitalization rate and infected population numbers are central indicators for lock-down policy-making, indicating whether the local medical system is able to handle the increasing infected population number through its available intensive care facilities. In fact, predicting hospitalization is vital for authorities and policymakers. We hereby hypothesize that high air pollutants concentration leads to a rise in the hospitalization rate under the influence of Covid-19 outbreaks. We attempt to predict such hospitalization numbers for past data by means of a task-specific optimized machine learning model, after we integrate social, economic, cultural, and other environmental features in future with an ongoing project we are conducting. While such a prediction model cannot directly be used for predicting the future development of the pandemic, analysing it still gives valuable insights on the influence of various environmental features had on it in the past.Air pollution is a mixture of a large number of chemical compounds such as CO2, CO, NOx, SO2, O3, heavy metals, and respirable particulate matter (PM2.5 and PM10); the main sources of such pollutants are identified as vehicle traffic, heating systems, and industrial plants [5]. Previous studies focused on the relationships between the variables of pandemic with the air pollutants information. Among all the air pollutants, NO2 and respirable articulate matter are highly related to the pandemic variables [6-8]. In our research, we extract the air pollutants information (CO, NO2, CH4, SO2) from the Sentinel-5P TROPOMI sensor, and integrate it with open-access data on Covid-19 features (mortality, infection rate, intensive care rate, etc). The air pollutant data is processed from the Sentinel-5P data catalog provided in Google Earth Engine. We therefore aim to ascertain the relationships between hospitalization and air pollutants concentration with the incidence of Covid-19. In particular, our ultimate research purpose is to develop a machine learning model to uncover the relationships between a mixture of features derived from air pollutants and Covid-19 related information, at municipality scales in Germany and the Netherlands. The relationships provide important clues on understanding how air pollution may affect on hospitalization rate and other features of Covid-19, through the evidence of potential low hospitalization or low mortality with better air quality. The output will deliver key information regarding public health effects and control of emission in Germany and the Netherlands.
Specifically, on a temporal scale, we aggregated daily Covid-19 data and four air pollutant measures into weekly measures. On a spatial scale, the air pollutants were aggregated based on each municipality in Germany and the Netherlands to match the Covid-19 features. A choice of machine learning models were trained and evaluated on historical data (from March of 2020 to Oct of 2021), using features comprising weekly hospitalizations, death rate, and infected rate, tropospheric NO2 concentration, CO, SO2, CH4 concentrations. In addition, a post-processing analysis using machine-learning explainability methodologies was carried out to mine potential relationships between hospitalization attributes and specific air pollution concentration features. By processing municipalities as separate spatial entities, the results are intended to highlight hospitalization disparities and pollutants’ effect diversities among different geographic areas.
By highlighting the relationships between air pollutant concentrations and incidence of Covid-19 with the hospitalization rate, and illustrating the hospitalization disparities among municipalities, our results provide key information regarding policymaking on urban emission control and public health at municipality level. When integrating other Covid-related features, our models could offer support to policymakers on effective lock-down decisions and health system management.

(European Space Agency (ESA))","","2021","The Fully-Focused SAR (FF-SAR) processing, introduced in Egido and Smith (2016) allows obtaining a maximum resolution of 0.5 m in the along-track direction. It provides significant benefits for inland water altimetry investigations allowing the successful investigation of very small rivers and canals (Kleinherenbrink, 2020) that are typically harder to be analysed by using unfocused Delay-Doppler SAR (DD-SAR) data (about 300 m resolution in the along-track direction).
In its development, two major limitations were associated with the FF-SAR processing: 1) the presence of evenly spaced high sidelobes in the Point Target Response (PTR) due to the closed-loop burst mode implemented in Sentinel-3 & Cryosat-2 altimeter payloads, used for initial FF-SAR investigations, and 2) the heavy computational burden with respect to the unfocused DD-SAR processing.
The first limitation can be overcome by designing the radar system differently adopting an open-loop transmission scheme as, for instance, the one implemented in the altimeter payload of the Sentinel-6 Michael Freilich mission, launched on 21 November 2020.
The second limitation has been addressed in research works following Egido and Smith (2016) indicating that an improvement in terms of computational burden can be achieved by adopting algorithms in the frequency domain (Guccione et al., 2018).
Being the role of FF-SAR for future inland water altimetry well understood, along with the possibility to see it implemented with reduced drawbacks during the Sentinel-6 Michael Freilich mission, a collaboration has started between the ESA GPOD Team, already hosting the successful SARvatore services portfolio for unfocused SAR & SARin altimetry, and Aresys.
Aresys has developed a generic FF-SAR prototype processor, that is able to process data acquisition from different instruments and exploiting the frequency-domain Omega-K algorithm (Guccione et al., 2018 & Scagliola et al., 2018). The Aresys's FFSAR prototype processor for CryoSat-2 allows users to process, on line and on demand, low-level CryoSat FBR products in SAR mode up to FF-SAR Level-1 products with self-customized options. Additionally a wide set of processing parameters is configurable, allowing as an example to select the along-track resolution or to obtain FFSAR multilooked waveforms at the desired posting rate.
The collaboration led to the creation of a new service for the processing of CryoSat Baseline D data in FF-SAR mode. Users will be able to select the following options: 1) range oversampling factor, 2) bandwidth factor (responsible for the along-track resolution value) and 3) multilook posting rate (1Hz-500Hz). Geophysical corrections and L2 estimates from both a threshold peak retracker and an ALES-like subwaveform retracker are part of the output package. In preliminary open ocean analyses, very good results on SSH noise have been obtained by the ALES-like subwaveform retracker.
In this presentation, the Aresys FF-SAR prototype processor is described and the outcome of some preliminary validation activities, performed by a group of altimetry researchers, is reported. The service is scheduled to open to all GPOD/SARvatore users in the first semester of 2021. Future evolutions should include the extension of the service to Sentinel-3 and Sentinel-6 data.
FFSAR processed data from CryoSat-2 in SAR mode is made freely available by ESA through a newly integrated service on the Grid Processing on Demand (G-POD) platform, within the SARvatore Family of custom processors, where the user can order data from an area and specify various parameters to be applied in the processing. The FFSAR processor has been developed within the ESA ESTEC Sentinel-6 Project and adapted to CryoSat-2 for verification and validation purposes.
Here we demonstrate the value of FFSAR and evaluate the FFSAR product obtained from the ESA G-POD service over different inland water targets. The evaluation and validation is done via in situ water level data, external processed FFSAR data, unfocused SAR data and laser altimetry data from ICESat-2.
More specific, we perform an evaluation over the narrow ( < 100 m) American Rivers: Red River, Little River, and Canadian River located in the Mississippi basin. Where we compare the water level based on different retracker e.g. ALES+ and threshold retrackers.
We make a joint water level time series by considering data from CryoSat-2 and ICESat-2 over a reach, and validate the results against in situ data. Preliminary results show that we can capture the main part of the water level signal.
Over the Elbe River, we compare the FFSAR based river water levels with results based on unfocused SAR processing and in situ gauges.
We extend our analysis with a case study conducted over the Lake IJssel which is located in The Netherlands and covers an area of approximately 1100 km2. We examine the performance of the G-POD processor by evaluating the FFSAR lake height estimates using externally processed FFSAR data that have been validated against in situ data.
We test this concept on data from numerical modelling using a subsurface model of the Groningen gas field for purposes of the DeepNL programme. The Rotliegend reservoir is located at depths between 2600 m and 3200 m, the total thickness of the Rotliegend in the Groningen field ranges from approximately 100 m to 300 m. The Groningen field is cut by several fault systems, subdividing the field into a large number of fault blocks.
We investigate utilization of non-physical reflections in multi-offset gathers and zero-offset gathers. From the multi-offset gathers, which are retrieved from SI by crosscorrelation, we show that in case of changes in the velocity and thickness of the Groningen reservoir, the non-physical reflections show a clear change. Furthermore, we show that the changes can be quantified. Thus, they can be used for monitoring purposes in the subsurface layers. The non-physical reflections in zero-offset gathers show very good conformity with the geometry of the specific subsurface layer, thus allowing imaging, e.g., of faults.","Seismic interferometry; Groningen gas field; Monitoring; Non_physical reflection","en","poster","","","","","","","","","","","Applied Geophysics and Petrophysics","","",""

The device has rapidly risen from a few percent to efficiencies of over 24% [1] in little over a decade. This rapid development is due in part to the wide family of perovskite absorber and of electron and hole tranport materials available which yields great flexibility. The flip-side of this profusion of materials is the challenge in establishing achievable performance potential of real devices. This paper therefore presents a study of the perovskite solar cell materials and applies numerical modelling techniques to evaluate the most promising materials combinations and their efficiency potential. The preliminary device structure is a simple three-layer design consisting of hole transport layer, perovskite aborber, and electron transport layer, on a glass substrate in a p-i-n or “inverted” configuration. A range of materials for these layers is compared and contrasted for this polarity. The structure is then generalised to more complex designs featuring protective buffer layers which prevent damage to the perovskite absorber layer, and two dimensional perovkite layers which have been shown to improve perovskite material stability. The realistic efficiency potential of the materials considered is discused in the context of the common radiative efficiency limit. The study concludes by recommending promising materials combinations for high efficiency PSC compatible with cost effective indutrial fabrication method for single juntion and for multijunction device design in the context of H2020 Solar-ERANET project BOBTANDEM [2]. This work contributes to define efficiencies achievable in this materials systems, both for single junction and multijunction devices which are of great societal interet for cost effective renewable power generation.","","en","poster","","","","","","","","","","","Photovoltaic Materials and Devices","","",""

(TU Delft Applied Geophysics and Petrophysics)","","2021","Induced seismicity from a gas-producing region such as Groningen is believed to be caused by reservoir depletion due to long-term gas production. However, because of the complexity and uncertainty regarding the underground structure and composition, it is difficult to quantify the effect on induced seismicity due to gas production. Here we use finite-element modelling to investigate the seismogenic potential of a pre-existing fault reactivated due to fluid depletion, considering different model settings. By applying quasi-static poroelastic loading representing reservoir depletion, the stress and strain fields are derived from the resulting displacement field. The equilibrium of the fault is then evaluated using either rate-and-state or slip-weakening behaviour for friction. When the critical state is reached on the fault, where the shear stress is greater than the friction, the reactivation of the fault takes place. This reactivation is simulated by using a dynamic solver to observe the propagation and the arrest of the dynamic faulting, as well as the resultant wavefield due to seismic slip. By comparing the depletion value at both aseismic and seismic ruptures, and looking at the stress distribution on the fault, the pattern of rupture nucleation, and the resulting seismic wavefield, we are able to evaluate separately the effect of different model settings, including the geometry and material property of both caprock and reservoir, reservoir depletion pattern, and the friction law. Furthermore, by combining our study with the observed seismic wavefield, it is possible to obtain useful insights on the spatial variation in the source region.","","en","poster","","","","","","","","","","","Applied Geophysics and Petrophysics","","",""

The proposed method is based on an impedance controller and includes four modes of operation, that are tailored for specific sub-tasks. Each mode prescribes a robot stiffness behavior, needed for collaborative execution. The human operator can easily switch between the mode in realtime via a voice interface. To demonstrate the functionality of the proposed method in the construction task, we performed an experiment using KUKA LBR iiwa robot arm and qb robotics SoftHand robotic hand.

(TU Delft Situated Architecture)","","2020","As the transformation of existing buildings is an ever-larger part of the architect’s portfolio, the research into the value and quality of existing structures gains importance. This research has long been the domain of art historians, who, in their cultural-historical investigations, evaluate (mostly monumental) buildings by positioning them within their time. Because these investigations only gives a limited understanding of the qualities of a building, this paper discusses the largescale physical model as a tool for the architect to understand the architectural qualities of a building and the relevance of using this knowledge as a basis for architectural transformations.
This paper is based on a research project into the architecture of the Museum Boijmans van Beuningen in Rotterdam, the Netherlands. The original museum of 1935 was extended three times over the past century, making the ensemble an architectural collection that represents the changing insights into museum building over time. The museum is currently planning an overhaul that includes the demolition of its latest two extensions in favour of a new wing. The project’s hypothesis was that a study using 1:5 models as an analytical tool could enable an intimate understanding of the qualities of the museum. This could then lead to the design of a series of small-scale interventions, as an alternative to the unsustainable and expensive logic of demolition and new construction.
Based on visit to the building, and therefore on a concrete, physical experience of its architecture, a series of six fragments were chosen that represent key architectural moments within the ensemble, such as a fragment of a façade or a threshold between two galleries. Together with a group of master students, these fragments were built at scale 1:5, using concrete, wood and plaster, mimicking the act of building the museum itself. On the basis of this study, a series of six transformation proposals for the museum were developed, varying from the adding of a staircase to reorganise the circulation through the museum to the introduction of a window to improve the relation between inside and outside. These interventions were based on the architectural themes present in the models and informed by the issues the museum organisation wished to address.
Through the act of building the fragments of the museum in the studio, it was possible to acquire a refined understanding of the haptic qualities of the building’s architecture. In doing so, the models introduced a specific way of understanding architecture, one that locates the quality of the existing architecture in its details and its physical, material presence. This clearly influenced the transformation proposals, which all reinforced specific existing qualities of the building and acquired a similar precision and material quality as the 1:5 models itself. The project therefore shows how the act of largescale modelling can foster the skill to design precise, small scale interventions. In doing so, it shows the potential of the 1:5 model as a valuable addition to the tools of the architect when engaging in transformation projects.","","en","poster","","","","","","","","","","","Situated Architecture","","",""

After the retrieval, one of the receivers acts as a virtual seismic source whose response is retrieved at the second receiver. Correct response retrieval relies on assumptions, among other, of a lossless medium being illuminated homogeneously by sufficiently densely spaced sources (passive or active). When these assumptions are not met, non-physical reflections might appear in the results of SI due to insufficient destructive interference. These non-physical reflections are caused by internal reflections inside subsurface layers. However, the non-physical reflections could be used for monitoring changes in the subsurface layers that generate them.
We investigate utilization of non-physical reflections for monitoring velocity changes for purposes of the DeepNL programme. We simulate reflection experiments using an acoustic finite-difference modelling for a horizontally layered model and for a subsurface with inclined layers. We perform SI by autocorrelation and by cross-correlation. Comparing retrieved results with the directly modelled results, we confirm previous results that for a layered subsurface the retrieved ghost reflections can be used for multiple offsets. For inclined layers, zero-offset ghost reflections can be retrieved for the different receiver locations. Both types of non-physical reflections are sensitive to velocity change and thickness of the layer that cause them to appear in the SI results, so they can be used for monitoring purposes of the subsurface.","seismic interferometry; DeepNL; non-physical reflection; subsurface; monitoring; seismics","en","poster","","","","","","Accepted Author Manuscript","","","","","Applied Geophysics and Petrophysics","","",""

The performance of these automated systems was evaluated using performance indicators such as Mean Lateral Position and Standard Deviation of Lane Position. In this study, the Systems Theoretic Accident Modelling and Processes (STAMP) model was adopted to understand the relationships between the various components of the “Road System”, which in this study include the road authority, the automated vehicle system, elements of the road infrastructure, and weather conditions. Empirical data from the experiment is used to estimate the relationships between the different components, followed by the assessment of their impact on the performance of the automated vehicles. It was found that visibility conditions have a significant effect on detection performance, which worsens in rainy conditions especially under streetlights. It has been also observed that there is a significant difference in Lane Position between Left Curves and Straight sections, and between lane widths less than 250 cms and those that have larger widths. These findings are combined with the results from the STAMP analysis to formulate a set of road infrastructure requirements that would lead to safe performance of Lane Assistance Systems.","Automated Driving; Lane Assistance Systems; Systems Theory; Systems Theoretic Accident Modeling and Processes (STAMP); Infrastructure effects; Road design","en","poster","","","","","","","","","","","Transport and Planning","","",""

The goal of this paper is to implement the wavefront coding technique without affecting much of the original design, and the design has taken the complexity of imaging system into consideration. The optimized strength of cubic phase mask (CPM) is based on the analytical optimal solution for the task-based imaging system [J. Opt. Soc. Am. A 25, 1064 (2008)]. The noisy intermediate images of CPM system with highest spatial frequency of interest can be effectively restored by vector-based Richardson-Lucy algorithm. Restoration from the system with generalized CPM produces precise image position than the system with CPM does. In general, the CPM system procures modulation transfer function higher than 0.195 in the whole depth-of-field, and the mean squared error of the restored images are less than 5 %.","Extended depth-of-field; Cubic phase mask","en","poster","","","","","","","","","","","ImPhys/Optics","","",""

Moreover, more exploratory research, using optogenetics, is being conducted in rodents for a better understanding of the mechanisms that occur while delivering specific therapies. However, the availability of tailored neurotechnologies for such experiments is limited. This work reports the development and characterization of flexible, active spinal cord implants with optogenetic compatibility1,2 (Fig.1). A scalable and reproducible microfabrication process has been developed, using graphene3, a transparent, flexible and conductive material, to form the electrodes and interconnects of the implant. Small and thin4 electronic chips were assembled via flip-chip bonding processes either on graphene or on metal-on-graphene layers. Soft, polymeric encapsulation was employed to sustain the high flexibility and transparency of the implant. The result is an active prototype consisting of a multi-layered graphene structure between two polymeric-based encapsulation layers, with thin chips integrated on the implant and test pads for interconnection to the outside world. Raman spectroscopy and optical transmittance were employed for the characterization of the graphene layer while cyclic voltammetry and electrochemical impedance spectroscopy were performed to benchmark the electrical properties of the device. The assembly process of the chips was evaluated using four-point electrical measurements. In this work, the first transparent, graphene-based active implants have been developed (Fig. 2 and Fig. 3). The prototypes were extensively characterized and the results showed a transparency of ~80 % as well as no deterioration over time when soaked in saline solution or when bent under various angles. The graphene electrodes showed an impedance of ~8 kΩ at 1 kHz frequencies and the resistance after the bonding process ranged from 10 mΩ up to 16 Ω for individual connections, depending on the substrate used","","en","poster","","","","","","","","","","","Bio-Electronics","","",""

(TU Delft CRE Strategic Portfolio Management)","","2019","Purpose: The purpose of this study is to generate knowledge about the use of smart campus tools to improve the effective and efficient use of campuses. Many universities are facing a challenge in attuning their accommodation to organisational demand. How can universities invest their resources as effectively as possible and not in space that will be poorly utilized? The hypothesis of this paper is that by using smart campus tools, this problem can be solved. Design/methodology/approach: To answer the research question, previous survey at 13 Dutch universities was updated and compared with a survey of various universities and other organizations. The survey consisted of interviews with structured and semi-structured questions, which resulted in a unified output for 27 cases. Findings: Based on the output of the cases, the development of smart campus tools at Dutch universities was compared to that of international universities and other organizations. Furthermore, the data collection led to insights regarding the reasons for initiating smart campus tools, user and management information, costs and benefits and foreseen developments. Originality/value: Although the use of smart tools in practice has gained significant momentum in the past few years, research on the subject is still very technology-oriented and not well-connected to facility management and real estate management. This paper provides an overview of the ways in which universities and organizations are currently supporting their users, improving the use of their buildings and reducing their energy footprint through the use of smart tools.","Facilities management services; Public sector; Smart buildings; Space planning; Space utilization; Strategic facilities management","en","poster","","","","","","","","","","","CRE Strategic Portfolio Management","","",""

We analyse the computation of travel times in quasi-dynamic assignment models.
We formulate and check requirements for the correctness of resulting travel times, addressing both the calculation of travel times for individual routes and links itself, as well as the differences between travel times of different travel choices. We demonstrate that existing approaches for travel time computation in literature fail to satisfy all requirements and derive a new link travel time formula from vertical queuing theory that does meet all requirements.
We discuss expected changes to assignment results and methodological advantages for pathfinding and model extensions, including horizontal queuing. The new link travel time formulation is finally applied to three example scenarios from literature.","","en","poster","","","","","","","","","","","Transport and Planning","","",""

Fog - in particular, the associated reduction is visibility - presents a hazard to airport operations. Although tech- nology has improved to allow greater safety during fog events, protocol still requires more time between aircraft movements, often resulting in significant delays and cancellations. Yet, observations at Amsterdam’s Schiphol International Airport in the Netherlands (one of Europe’s busiest airports) suggest that the airport buildings and aircraft operations themselves may help to alleviate some of the fog hazard. Meteorological data from from a network of weather stations at and around Schiphol airport are used to assess the occurrence and severity of fog events. Runways located closer to airport terminals are shown to experience both fewer and shorter fog events than those at greater distances from the main terminal complex. Further, large aircraft - in particular Boeing 747s - are observed to raise local runway temperature and wind speed by as much as a few degrees under nocturnal stable boundary layer conditions, which can have a significant impact on the formation of local fog. These find- ings present an interesting look at the local influence of airport construction and aircraft operations, suggesting that they may ultimately lead to ""built-in"" fog mitigation beyond the natural, undisturbed state. The benefit likely grows with the size of the airport. The larger and busier the airport (such as Heathrow, or Paris-Charles de Gaulle), for example, the more damaging a fog event can be, but the greater potential for disruption of fog formation due to greater number of aircraft movements.","","en","poster","","","","","","","","","","","Atmospheric Remote Sensing","","",""

(Royal Netherlands Meteorological Institute (KNMI))","","2019","Conventional in situ observations of visibility and other meteorological variables are restricted to a limited number of heights near the surface, with the lowest observation often made above 1 m. This can result in missed observations of shallow fog as well as the initial growth stage of thicker fog layers. At the same time, numerical experiments have demonstrated the need for high vertical grid resolution in the near-surface layer to accurately simulate the onset of fog; this requires correspondingly high-resolution observational data for validation. In November 2017, a field experiment was conducted at the Cabauw Experimental Site for Atmospheric Research (CESAR) in the Netherlands with the aim of observing the growth of shallow fog from the ground up, assessing the applicability of emerging high-resolution methods for observing shallow fog. Two innovative, high-resolution techniques were employed: distributed temperature sensing (DTS), providing temperature and relative humidity observations at vertical resolutions as fine as 1 cm, and a novel camera-LED method to observe near-surface visibility below the conventional sensor height of 2.0 m. These observations were supplemented by the existing observations at the site, including those along a 200-m tall tower. Comparison between the high-resolution observations and their conventional counterparts shows the errors to be small, giving confidence to the reliability of the techniques. The high resolution of the observations subse- quently allows for detailed investigations of near surface processes. The growth of fog layers from the ground up was observed with very strong temperature inversions in the lowest metre (up to 5 K), and corresponding region of (super)saturation where the fog formed and grew. Throughout the two-week observation period, fog was observed twice at the conventional sensor height of 2.0 m, but up to four times in the lowest 0-0.5 m using the camera estimates, with the shallow fog also forming up to two hours before it was observed by the conventional sensor. The observations are supplemented by high-resolution numerical simulations of the experimental period, highlighting the sensitivity of the fog layer to surface properties and ambient conditions, providing greater insight into what drives the growth of a very shallow fog layer (i.e. < 1 m) into a deeper, and therefore more dangerous, layer.","","en","poster","","","","","","","","","","","Atmospheric Remote Sensing","","",""

With the increasing severe ecological challenge of urban high-density area and rising ecological awareness, people gradually realized the importance of biodiversity and began to explore the impact of urbanization on the biotope. This study in the city of Shanghai sets the framework for a study of the relation between spatial morphology and urban biotope, aims to discuss the impact of urbanization on the urban biotope. Two of high-density urban spaces and sub-urban spaces in the context of Shanghai area were examined as case studies, Huangpu District and Pujin Block, to demonstrate the biotope situations by disparate urbanization impact. In each study area, the urban biotope mapping methodology was developed base upon a general biotope classification method adapted to urban context. Main outputs are GIS based maps representing different biotopes, showing spatial difference in each area. Seven core biotope evaluation indicators of urban biodiversity were calculated: 1) area; 2) density; 3) shape index; 4) diversity index; 5) saturation index; 6) fragmentation index; 7) value index. Huangpu District and Pujin Block, although similar in size, exhibit distinct characteristics and perform different biotope situation by the impact of urbanization. This research aims to contribute to a better understanding and promotion of the relationship between biotope and urbanization, particularly for the disciplines involved in urban landscape planning, design and management.","biotope; urbanisation; Shanghai; Huangpu District; Pujin Block","en","poster","","","","","","","","","","","Environmental Technology and Design","","",""

Mechanically-controlled break junction (MCBJ) is a great tool for characterizing molecular properties and their response to different stimuli including light, solvent and importantly, mechanical deformation1. In our recent MCBJ experiment, we showed that the conductance of a spring-like molecule can be mechanically tuned up to an order of magnitude at room temperature2. The physical origin of such feature is a consequence of destructive quantum interference between the frontier orbitals. This indicates not only a possible application for mechanical sensors based on this class of molecules, but also demonstrates a good example of quantum interference effect in single molecules. Following this intriguing result, we investigate other properties of this molecule, such as I-V characteristics at low temperature and thermopower. We are also exploring other molecules with similar spring-like structures, where quantum interference effect is expected to manifest.","","en","poster","","","","","","","","","","","QN/van der Zant Lab","","",""

However, the choice of a hydrodynamic model for a specific area in terms of cost, efficiency and accuracy is often a dilemma at the beginning of a modeling project. The objective of this research is to examine the effects of two software packages in terms of accuracy and performance with a case study in the Shanghai area of China. Model performance has been assessed based on model configuration, model calibration, grid generation and computational efficiency. Comparing measured water levels with model results, both approaches were able to accurately predict hydrodynamic conditions in a complex estuarine environment. Both models showed that it can efficiently simulate hydrodynamics in the coastal area under various scenarios for further climate adaptation research. Additionally, both models were used to simulate inundation propagation due to hypothetical failures of flood defenses in the coastal area. A comparison of inundation extent and maximum inundation depth showed that they were equally well-suited for overtopping and inundation simulation.

An application of the methodology to several commonly-used solution time-series reveals that the ITSG-Grace2016 solutions show the highest accuracy among those considered. Furthermore, it is found that the accuracy of background models exploited to produce GRACE RL05 solutions was likely insufficient to describe adequately mass re-distribution in the oceans at both short (< 1 month) and long (>1 month) time scales.

However, satellite gravimetry still suffers from a poor estimation of temporal variations in the spherical harmonic coefficient C20 (which is associated with the Earth's dynamic oblateness). Therefore, these variations are typically extracted from Satellite Laser Ranging (SLR) data. Furthermore, satellite gravimetry is not sensitive to variations of degree-1 spherical harmonic coefficients (i.e., C10, C11, and S11), which are associated with the geocentre motion. Swenson et al (2008) proposed to restore those coefficients using as a reference an area where the mass anomalies are known. Such an area was chosen as the entire world ocean; mass anomalies there were defined as variations of the Ocean Bottom Pressure based on an ocean circulation model. The Glacial Isostatic Adjustment signal was corrected for by applying a remove-restore approach.
Sun et al (2016) further developed the technique by Swenson et al (2008). First, the Self-Attraction and Loading (SAL) effects were additionally modelled in order to estimate water re-distribution in the ocean more accurately. Second, a buffer zone around the continents was excluded from the reference area in order to suppress the effect of “signal leakage” caused by a limited spatial resolution of satellite gravimetry. It was shown that the modified technique allows for an accurate estimation of both degree-1 and C20 variations.","","en","poster","","","","","","","","","","","Physical and Space Geodesy","","",""

In this paper we report case-specific, participatory co-design process that occurred in Texel, the Netherlands, where local stakeholders were asked to collaboratively design (“co-design”) utopian and dystopian future visions. We applied an action-type method that addresses the need for empirical exploration of underlying stakeholder values. Professionals with specialized expertise joined in transdisciplinary activities for co-design iteratively towards feasible solutions. Final designs were validated by local participants on value-consistency. A number of considerations contributed to the success of this collaborative and transdisciplinary approach: working directly and locally with local stakeholders; appreciating the local knowledge, stakeholder preferences and underlying stakeholder values; prioritizing a multi-directional flow of information; and engaging professional multidisciplinary specialists in the social-ecological system. Experiences gained from this approach can be used as input for next iterations of collaborative design activities, for the Texel coast and elsewhere.","","en","poster","","","","","","","","","","","Policy Analysis","","",""

Plasticicumulans acidivorans are polyhydroxybutyrate (PHB) accumulating bacteria enriched from activated sludge using carbon feast-famine cycles as selective pressure. Despite growing slowly, P. acidivorans outcompetes other bacteria by quickly taking up acetate and storing it intracellularly as PHB to later use it for growth. As soon as acetate is depleted, these bacteria immediately ‘switch’ their metabolism from PHB production to consumption entailing a very interesting regulatory challenge as parallel activity could lead to significant losses (futile cycling). While the stoichiometry for both feast and famine phases has been extensively described in literature, the switch regulation is not yet fully understood. To elucidate the responsible regulatory processes, an enrichment of P. acidivorans was studied using targeted intracellular metabolite analysis over time, with emphasis on the feast to famine switch. In combination with extracellular rates, the measured intracellular metabolite pools are used to design a labelling experiment to obtain actual intracellular fluxes (dynamic 13C flux analysis). Here the challenge is to create an isotopically non-stationary state (usually mediated by changing the substrate’s isotopic composition) to study the metabolic response in the transition from presence-to-absence of substrate.In this way, we aim to unravel the responsible regulatory mechanism governing the metabolic switch from storage-to-consumption and use this knowledge not only to understand its ecological relevance, but to also propose novel metabolic strategies for microbial cell factory design.","","en","poster","","","","","","","","","","","OLD BT/Cell Systems Engineering","","",""

The primary function of a wavelength meter is to provide an output signal that changes sensitively with the wavelength of the input light. Of central importance is the reproducibility of the output signal even in the presence of external perturbations, e.g., temperature changes causing thermal drift. Various different methods are usually applied to improve reproducibility, e.g., thermal stabilization or repeated calibration with an additional reference light source of well-known and stable wavelength.","","en","poster","","","","","","","","","","","Team Raf Van de Plas","","",""

(TU Delft Reservoir Engineering)","","2017","Foam can be applied as an Enhanced Oil Recovery (EOR) process. Foam stability in porous mediadecreases with decreasing surfactant concentration. It is also known that foam collapses belowa “limiting water saturation” in porous media. However, there isn’t a complete theory for the relationship between surfactant concentration and the water saturation below which foam coarsens ina specific porous medium. The aim of this study was to find a relationship between the surfactantconcentration, the foam bubble radius, and the limiting water saturation. This research gathersand analyses experimental data from the literature on foam properties in porous media. The foamswere stabilized with the same anionic surfactant (AOS), at different surfactant concentrations andporous media.The experimental data shows that for a specific porous medium, the limiting water saturation exponentially decreases with increasing surfactant concentration. These results can be explainedby the surfactant depletion from the solution to the gas-water interface. This work shows that thelimiting water saturation approximates the water saturation for which the gas-water interfacial-areais equal to the surface-area that could be covered by the surfactant molecules in the surfactant solution in the given porous medium. A fundamental assumption in this calculation is that gas bubblesin the porous medium correspond to pore size, as is thought to apply to foams at water saturationsabove the limiting water saturation.The general implication of these results is that from two known parameters, the third parameter canbe calculated (the three parameters are surfactant concentration, the average foam bubble sizeand limiting water saturation). A possible implication on the modelling of the foam flood in porousmedia was investigated in this research. The observed relationship was applied to a simulation ofsurfactant-alternating-gas injection in a homogenous reservoir with a uniform residual oil saturation. In this simulation the limiting water saturation was a function of the foam bubble size and thesurfactant concentration","","en","poster","","","","","","","","","","","Applied Geophysics and Petrophysics","","",""

(TU Delft Aircraft Noise and Climate Effects)","","2017","This paper presents a methodology with which aircraft designs can be modified such that they produce optimal sound signatures on the ground. With optimal sound it is implied in this case sounds that are perceived as less annoying by residents living near airport vicinities. A novel design and assessment chain has been developed which combines the aircraft design process with an auralization and sound quality assessment capability. It is demonstrated how different commercial aircraft can be designed, their sounds auralized at representative locations in airport vicinities and subsequently assessed for sound quality. As sound quality is closely related to the perceived annoyance, it is expected that designs with improved sound quality would also be perceived as less annoying. By providing a feedback to the design optimizer in terms of one of the sound quality metrics or a suitable combination thereof, the designs of aircraft can be altered to produce potentially less annoying sounds. The paper will focus on three current aircraft and will demonstrate the application of the novel design chain to auralize and alter their sounds toward improved sound quality. The presented methodology can also be extended to unconventional aircraft configurations and propulsion concepts, for optimizing future aircraft sounds.","","en","poster","","","","","","","","","Aerospace Engineering","","Aircraft Noise and Climate Effects","","",""

In the current methods, in which only the horizontal linear accelerations are used, the vertical winds cannot be obtained. In the algorithm proposed in this paper, angular accelerations derived from the individual gradiometer accelerations are used to obtain the vertical wind speeds as well. To do so, the measured angular rate and acceleration are combined to find a measurement of the torque acting on the spacecraft. This measurement is then corrected for modeled control torque applied by the magnetic torquers, aerodynamic torque, gravity gradient torque, solar radiation pressure torque, the torque caused by the misalignment of the thrust with respect to the center of gravity, and magnetic torque caused by the operation of several different subsystems of the spacecraft bus. Since the proper documentation of the magnetic properties of the payload were not available, a least squares estimate is made of one hard- and one soft-magnetic dipole pertaining to the payload, on an aerodynamically quiet day. The model for aerodynamic torque uses moment coefficients from Monte-Carlo Test Particle software ANGARA. Finally the neutral density, horizontal cross-wind, and vertical wind are obtained from an iterative process, in which the residual forces and torques are minimized. It is found that, like horizontal wind, the vertical wind responds strongly to geomagnetic storms. This response is observed over the whole latitude range, and shows seasonal variations.","","en","poster","","","","","","","","","","","Astrodynamics & Space Missions","","",""

(TU Delft Astrodynamics & Space Missions)","","2017","Since 2000, accelerometers on board of the CHAMP, GRACE, GOCE and Swarm satellites have provided highresolution thermosphere density data, improving knowledge on atmospheric dynamics and coupling processes in the thermosphere-ionosphere layer. Most of the research has focused on relative changes in density. Scale differences between datasets and models have been largely neglected or removed using ad hoc scale factors. The origin of these variations arises from errors in the aerodynamic modelling, specifically in the modelling of the satellite outer surface geometry and of the gas-surface interactions. Therefore, in order to further improve density datasets and models that rely on these datasets, and in order to make them align with each other in terms of the absolute scale of the density, it is first required to enhance the geometry modelling. Once accurate geometric models of the satellites are available, it will be possible to enhance the characterization of the gassurface interactions, and to enhance the satellite aerodynamic modelling. This presentation offers an accurate approach for determining aerodynamic forces and torques and improved density data for CHAMP, GRACE, GOCE and Swarm. Through detailed high fidelity 3-D CAD models and Direct Simulation Monte Carlo computations, flow shadowing and complex concave geometries can be investigated. This was not possible with previous closed-form solutions, especially because of the low fidelity geometries and the incapability to introduce shadowing effects. This inaccurate geometry and aerodynamic modelling turned out to have relevant influence on derived densities, particularly for satellites with complex elongated shapes and protruding instruments, beams and antennae. Once the geometry and aerodynamic modelling have been enhanced with the proposed approach, the accelerometer data can be reprocessed leading to 81 higher fidelity density estimates. An overview of achieved improvements and dataset comparisons will be provided together with an introduction to the next gas-surface interactions research phase.","","en","poster","","","","","","","","","","","Astrodynamics & Space Missions","","",""

(TU Delft Offshore and Dredging Engineering)","","2017","Most methods for determining the hydraulic gradient of slurry transport are based on a single particle size. A few methods describe how to deal with a graded Particle Size Distribution (PSD). The way these methods deal with graded PSD's is very different. The original Durand/Condolios method defines an equivalent particle diameter, based on a weighted average of particle Froude numbers using the parallel resistor method. The heterogeneous Wilson model uses a power for the dependency of the hydraulic gradient on the line speed, where this power is smaller, the more graded the PSD. This power has a maximum of 1.7 for single sized particle solids and a minimum of 0.25 in the Wilson model. The Sellgren & Wilson 4 component model divides the PSD in 4 components based on particle size boundaries. For each particle size based component, the corresponding model is applied. These models are the homogeneous model for very small particles influencing the viscosity, the reduced Equivalent Liquid Model for small particles, the heterogeneous model for medium sized particles and the two-layer and three layer models for large particles. The 4th model considered is the Delft Head Loss & Limit Deposit Velocity Framework, dividing the PSD in fractions. The number of fractions is free to choose, but normally 9 is sufficient. First the carrier liquid properties are adjusted based on the fines fraction. Secondly the hydraulic gradient curve is determined for each fraction. These hydraulic gradient curves are added, multiplied with the fraction. The paper describes the 4 methods and gives pros and cons of each method. The 4 methods are compared with each other. © BHR Group Hydrotransport 20.","","en","poster","","","","","","Voor overeenkomstige PowerPoint-presentatie zie: https://www.researchgate.net/profile/Sape_Miedema/publication/317684169_Paper_12_Miedema/data/5948c4b3458515db1fd71cb3/Paper-12-Miedema.pdf","","","","","Offshore and Dredging Engineering","","",""

It is well known that CDAs present potential benefits in terms of community noise impact with reductions in excess of 5 dBA in peak noise levels. It is however unclear if these reductions in A-weighted level, which is a poor predictor of perceived annoyance, also correspond to an improvement in the quality of the aircraft sounds that reach the residents on the ground. A real comparison can only be made by comparing the sounds an aircraft produces while flying a CDA with a standard approach procedure. A short-range and a long-range aircraft are simulated to fly a standard approach procedure and a CDA with 3, 4, and 5 degree glideslope angle. The noise produced over both approach procedures is then auralized at representative ground locations, and the sounds are analyzed for changes in sound quality. Quantifying the changes in the aircraft sounds in terms of sound quality metrics provides much clearer information regarding how the sound the residents hear has changed, and if the CDAs actually result in an improved sound quality and hence lower annoyance.","","en","poster","","","","","","","","","","","Aircraft Noise and Climate Effects","","",""

(TU Delft OLD Public Buiding)","","2016","A work of architecture occupies a delicate position between functional performance and production of certain meaning and experience. The design of architecture becomes stifling when an architects attempts to harmonize the two facets. Modernist architects argued that a building should express materiality and assemblage in the most direct, “honest” way without embellishment. This view suggests that architecture should be designed so as to demonstrate the logic and efficiency of materials and assembly, the techné as embodiment of Aristotelian causalities. Postmodernist architects insisted that a building consists of “signs” that are applied to functionally generic structure. This view suggests that the meaning of architecture depends on the cultural context and architecture must augment the legitimacy of the given cultural discourse. As such, architecture may be made to express many different meanings
while the fundamental technics remain the same in each instance. In this poster, I will describe a tectonic-indexical approach to the design of architecture. I will first approach Peirce’s triadic sign system (icon, symbol and index) and its application to
architecture. Next, I will discuss and link together indexicality, extra-somatic construct and tectonic aggregation in the context of architectural semiosis. In the process, I will argue for the view of architectural work as “instantiation” of semiotic assemblage that is driven by the intimate combination of tactility and algorithmic abstraction that epitomizes today’s apparatus-centric semiosis. In the process, I will demonstrate how architecture can be designed in a symbiosis of tactile and visual composition specific to the tooling and assembly of materials and forms, and how such construct opens up to new potentialities of producing meaning in architecture. I
will conclude the paper with a speculation of a new environmental criticality. On a larger context, I foresee the post-human semiotic architectural composition in which material ontologies of human-specific culture take a new turn.","","en","poster","","","","","","","","","","","OLD Public Buiding","","",""

MBES surveys in extensive shallow shelf areas can be a rather challenging and time-consuming task, resulting in time and cost intensive data collection. It is therefore often the problem of dealing with sparse data and/or data without full coverage. This study deals with MBES data acquired within an area of approximately 30 x 55 km (Cleaverbank, North Sea, the Netherlands) with a line spacing of ~2 km in 50 m average water depth. Additionally ground truth samples were taken with a Hamon grab in a regular grid of ~1 x 1 km with samples at and in-between some of the MBES survey lines. These ground truth data cover a subset of the area under investigation from variable depth and sediment types ranging from silty clay to boulders. Here we combine geostatistical and multivariate modelling for predictive mapping of the median grain size across the whole area. First bathymetric data was cleaned and raw backscatter values were classified into 7 classes representing different sediment types using a Bayesian method. A multiple linear regression was performed with the ground truth (sediment grain size) data resulting in an empirical function that shows high correlation (90%) of the median grain size with depth and backscatter classes. However missing information in un-surveyed areas needs to be estimated before predictive mapping can take place. For this purpose we interpolated sparse bathymetric and backscatter class data in order to obtain layers of continuous information for the whole area. To achieve this, MBES lines were treated as Single Beam Echo-Sounder data by producing a reduced, equally-spaced grid of bathymetry and backscatter class points, for each MBES line. Interpolation of this bathymetric data set using Ordinary Kriging (OK) yielded satisfactory results with low root-mean-square errors. For the backscatter class we utilized both OK and a Bayesian Maximum Entropy (BME) algorithm which is regarded as more suitable for categorical data. As backscatter classes are ordered by increasing acoustic intensity makes the interpolation results useful as they also include values between classes. Interpolated bathymetry and backscatter classes were validated with additional data from crossing lines. Subsequently, the interpolated layers produced by geostatistical modelling became input to the empirical regression function connecting median grain size and MBES data. The predictive layer of median grain size was assessed by using independent ground truth data from not-mapped locations. By applying linear regression to the interpolated data it was found that both, OK and BME provided results that predict median grain sizes with a high correlation (up to r2=0.85) to the observed values. The overall approach suggests that the combination of geostatistical with multivariate modelling can offer good results for large scale seafloor classification when data are limited. Additionally the prediction accuracy for each layer (bathymetry, backscatter class) can be estimated and spurious results can be identified.","","en","poster","","","","","","","","","","","Aircraft Noise and Climate Effects","","",""

(TU Delft Aerospace Structures & Materials)","","2016","Computing global strain distributions in complex aerospace and wind energy structures in quasi-real time is an important challenge for the aerospace and wind energy industry. Shape sensing is being considered as a potential means for obtaining global strain fields of complex structures. This is achieved through the use of inverse finite element methods (iFEM). Traditional shape sensing techniques use a variety of sensors in isolation. These isolated approaches lead to a number of drawbacks, including significant errors in the strain and/or displacement distributions that they determine. This study focuses on reducing these errors by combining data from various sensor types.
In order to achieve this objective, a new iFEM approach was developed to improve how shape sensing determines a structure’s deformation from distributed sensors. The method utilizes a procedure that minimizes a quadratic error functional, based on the difference between the theoretical and the measured strains and displacements. The analytical iFEM equations are discretized for use in a numerical model, which is used to analyze simulated sensor data. The simulated data is obtained from a FEM analysis of a structure loaded in bending, torsion and shear, in addition to experiencing combined loads. As with previous inverse methods, the error functional weights were employed to manage missing measurements and Tikhonov regularization was applied to guarantee smoothness of the numerical solution.
In this study, it has been shown that the new iFEM methodology can determine the structural deformations to within 1% of the FEM results for each of the load cases. In addition, the methodology is capable of achieving the same accuracy as single sensor type iFEM methods with a smaller total number of sensors. The single sensor type iFEM methods that were considered made use of only strain data or only displacement data. Finally, an experimental setup consisting of a simple cantilever plate structure was constructed in order to experimentally verify the newly developed iFEM algorithm. The experimental strain and displacement data were obtained utilizing a Rayleigh backscattering fiber optic distributed sensing system and MEMS sensors, respectively. Both of these sensor types were mounted on the structure and subjected to the load cases that were simulated in the FEM analysis.","","en","poster","","","","","","","","","","Aerospace Structures & Materials","Structural Integrity & Composites","","",""

Calcium carbonate crystallizes on a seeding grain of garnet or sand and calcium
carbonate pellets are produced as a by-product. These pellets are applied as a (secondary) raw material in industries such as the construction, agricultural and mineral-resource sector. The sand grain inside the pellet inhibits reuse as seeding material and application in high potential market segments such as glass, paper, food and feed. Pellet quality significantly improves by replacing the
sand grain with a grain of calcite (calcium carbonate) since in such way the pellet exists of one component only and the iron content is reduced.
Earlier work showed that it is technologically possible and in some cases economically feasible to replace sand grains with commercially available calcite grains [3], obtained from limestone quarries (e.g. Italy or Germany). In order to further increase sustainability by reducing transportation, the drying, grinding and sieving of pellets and the reuse of this calcite as seeding material for softening was investigated on pilot scale at Waternet. Currently, the calcite reuse concept is tested at full scale at the Weesperkarspel facility of Waternet in a TKI project1. The objective is to investigate the feasibility of this reuse concept. An important aspect is the risk of contamination of the drinking water due to the reuse of calcite material which is processed externally.","","en","poster","","","","","","","","","","","Geo-engineering","","",""

Therefore, they are of great scientific interest. Their behaviour is governed by the delicate balance of oceanic processes such as tides, waves and mean sea level (MSL), and fluvial/estuarine processes such as riverflow. All of these processes can be significantly affected by climate change (CC) processes, which may result in negative physical impacts such as inlet closure/relocation, creation of new inlets, erosion of the coast adjacent to the inlet etc. Although CC impacts on some large tidal inlets (e.g. Wadden Sea inlets) have received some attention recently, the potential CC impacts on small tidal inlets (STIs) remain virtually unknown to date. Furthermore, whether currently available predictive tools are capable of simulating CC impacts on these systems also remains unknown. These knowledge gaps are a serious threat to effective adaptation to CC in STI environments. Just, this study attempts to investigate the potential range of CC impacts on the stability (i.e. closed/open state and locational stability) of STIs via the application of a sophisticated process based morphodynamic model (Delft3D) to strategically selected schematised inlet morphologies and forcing conditions.Results indicate that CC driven variations in system forcing are likely have profound impacts on inlet stability and also show that a process based coastal morphodynamic model (eg. Delft3D) is suitable for investigating potential CC impacts at small tidal inlets.","","en","poster","","","","","","","","","","","","","",""

We analyzed the DNA methylation
(DMP) and gene expression profiles (GEP) of 344 AML patients using an unsupervised and supervised approach. We hypothesized to better
characterize the disease phenotype by combing these features as these may result in specific patterns in cancer cells which reflect biological
differences. The unsupervised approach segregates patients into 18 clusters, among them six clusters that are defined by the World Health Organization, such as inv16, t(15;17), t(8;21) and CEBPA double mutants. In addition we identified four novel AML subtypes that could not be explained by the enrichment of any currently known recurrent cytogenetic, molecular, morphological or clinical feature. Two of these clusters are categorized with good stability. One of these cluster could be characterized with pathways that are involved in the accumulation of red blood cells and highly predictable using 21 GEP and 3 DMP features, whereas the other cluster is characterized with T-cell related pathways and highly predictable with 9 GEP and 4 DMP features.","","en","poster","","","","","","","","","","","Pattern Recognition and Bioinformatics","","",""
