Alkemade, C. (author), Wierenga, H. (author), Volkov, V. (author), López, Magdalena Preciado (author), Akhmanova, Anna (author), ten Wolde, Pieter Rein (author), Dogterom, A.M. (author), Koenderink, G.H. (author)The actin and microtubule cytoskeletons form active networks in the cell that can contract and remodel, resulting in vital cellular processes such as cell division and motility. Motor proteins play an important role in generating the forces required for these processes, but more recently the concept of passive cross-linkers being able to...journal article 2022

Kammouh, O. (author), Kok, M.W.A. (author), Nogal Macho, M. (author), Binnekamp, R. (author), Wolfert, A.R.M. (author)Changes in a construction project schedule can impact the project's planned duration, resulting in penalties. A manual trial-and-error probabilistic approach is usually conducted to find an appropriate set of corrective measures to mitigate delays of the overall project. However, this approach does not capture the actual goal-oriented...journal article 2022

Egberts, G. (author), Schaaphok, Marianne (author), Vermolen, F.J. (author), Zuijlen, Paul van (author)Burn injuries can decrease the quality of life of a patient tremendously, because of esthetic reasons and because of contractions that result from them. In severe case, skin contraction takes place at such a large extent that joint mobility of a patient is significantly inhibited. In these cases, one refers to a contracture. In order to...journal article 2022

Keim, Josephine (author)Interest rate products form a large segment of over-the-counter derivatives. When the interest rate became negative, for the first time, in July 2009, interest rate models needed to adjust. Where first a log-normal model, as the Brace Gatarek Musiela (BGM) model, might have seemed logical for interest-rate products, as they were<br/>bounded by...master thesis 2021

Postma, Jelmer (author)Surface compositions play a predominant role in the efficiency and lifetime of membranes and catalysts. The surface composition can change during operation due to segregation, thus controlling and predicting the surface composition is essential. Computational modelling can aid in predicting the alloy's stability, along with designing surface...master thesis 2021

Chen, Y. (author)Single-photon emission computed tomography (SPECT) is a well-established nuclear imaging modality for studying functional and pathological properties of the brain. Conventional general purpose SPECT systems typically offer a spatial resolution of about 10 mm with a sensitivity of 0.01-0.02%. A few dedicated brain SPECT scanners have been...doctoral thesis 2021

Nguyen, M.P. (author)Molecular imaging aims for the visualisation, characterisation, and quantification of biological processes in humans and other living systems at the molecular and cellular level. For today’s patient care, molecular imaging allows for (early) detection and characterisation of disease, efficient planning and assessment of treatments, and...doctoral thesis 2021

Dennis Djohan, Dennis (author)This research is part of the project "Water Efficiency in Sustainable Cotton-based Production Systems” between Solidaridad Asia and TU Delft. The project aims to increase the livelihood of smallholder farmers in the Maharashtra, India through. A socio-hydrological (SH) model is used extensively in this research as an evaluation tool. However,...master thesis 2021

Kindermann, Paulina (author)Since 2017, Dutch flood defences are assessed according to new safety standards. These standards are based on flooding probabilities and rely on several assumptions and approximations. There are concerns that the combination of these assumptions leads to conservative results. Recently computed probabilities of failure are...master thesis 2021

Rapp, S. (author)Airborne wind energy (AWE) is a novel technology that aims at accessing wind resources at higher altitudes which cannot be reached with conventional wind turbines. This technological challenge is accomplished using tethered aircraft or kites in combination with either onboard or ground-based generators. In the former case, the kinetic energy of...doctoral thesis 2021

Han, Han (author)Soil properties are spatially variable due to the natural deposition process. Because of this inherent spatial variability, a slope can actually fail along any potential slip surface. A single value of Factor of safety cannot account for this variation dominated the slope stability problem. Probabilistic analysis considering the spatial...master thesis 2021

Klijnjan, Tim (author)Synchronisation is the remarkable phenomenon of in-phase movement of coupled oscillators during a prolonged period of time, which even occurs when these have different natural frequencies. This property is used in many fields like physics, biology and chemistry, to model various system behaviours, for instance: circadian rhythms in the chemistry...bachelor thesis 2021

Ökmen, Ö. (author), Bosch-Rekveldt, M.G.C. (author), Bakker, H.L.M. (author)Scheduling of a construction project using an activity network can be done using the Critical Path Method (CPM). CPM scheduling, since it was first developed in the USA in 1950’s, has been widely applied in various sectors including the construction sector. CPM, however, is incapable of reflecting the influence of uncertainty on schedules and...conference paper 2021

(author)Commercial aviation distinguishes three indicators for third party risk (TPR): i) Expected number of ground fatalities per aircraft flight hour; ii) Individual risk; and iii) Societal risk. The latter two indicators stem from TPR posed to population by operation of hazardous installations. Literature on TPR of Unmanned Aircraft System (UAS)...journal article 2021

Ma, H. (author), Psychas, D.V. (author), Xing, Xuhuang (author), Zhao, Qile (author), Verhagen, S. (author), Liu, Xianglin (author)The tropospheric delay is one of many error sources that affect the Global Navigation Satellite System (GNSS) positioning solutions. The widely used troposphere models assume a homogeneous atmosphere so that only the zenith delay needs to be determined and is mapped through an elevation-dependent mapping function. This procedure is to reduce...journal article 2021

(author), Koenderink, A. Femius (author)Photon recycling, the iterative process of re-Absorption and re-emission of photons in an absorbing medium, can play an important role in the power-conversion efficiency of photovoltaic cells. To date, several studies have proposed that this process may occur in bulk or thin films of inorganic lead-halide perovskites, but conclusive proof of...journal article 2021

(author)The use of multi-pinhole collimation has enabled ultra-high-resolution imaging of SPECT and PET tracers in small animals. Key for obtaining high-quality images is the use of statistical iterative image reconstruction with accurate energy-dependent photon transport modelling through collimator and detector. This can be incorporated in a system...journal article 2021

Chen, Y. (author), Goorden, M.C. (author), Beekman, F.J. (author)SPECT imaging with 123I-FP-CIT is used for diagnosis of neurodegenerative disorders like Parkinson's disease. Attenuation correction (AC) can be useful for quantitative analysis of 123I-FP-CIT SPECT. Ideally, AC would be performed based on attenuation maps (μ-maps) derived from perfectly registered CT scans. Such μ-maps, however, are most...journal article 2021

Kammouh, O. (author), Nogal Macho, M. (author), Binnekamp, R. (author), Wolfert, A.R.M. (author)Probabilistic Monte Carlo simulations are often used to determine a project's completion time given a required probability level. During project execution, schedule changes negatively affect the probability of meeting the project's completion time. A manual trial and error approach is then conducted to find a set of mitigation measures to...journal article 2021
