Su, Kevin (author)To protect critical services in today's society it is necessary to mitigate and prevent risks threatening the reliability of the internet. Internet-of-Things (IoT) devices are the number one attack target on the internet. The situation will become worse as there will be an expected 40 billion IoT devices in 2025. IoT bot activity represented 78%...master thesis 2021

Influence of the combination of ambient and glacial stresses on the response of a viscoelastic EarthMorra, Fabrizio (author)The evolution of ice loads during the last Ice Age causes an ongoing Earth response with deformations and stress fields. The viscosity of the mantle depends on stresses, therefore the model stresses should be combined with ambient stresses such as due to mantle convection. This combination has been successfully simulated in the FEM software...master thesis 2021

Pols, C.F.J. (author), Dekkers, P.J.J.M. (author), de Vries, M.J. (author)This paper explores students’ ability to analyse and interpret empirical data as inadequate data analysis skills and understandings may contribute to the renowned disappointing outcomes of practical work in secondary school physics. Selected competences, derived from a collection of leading curricula, are explored through interviews and...journal article 2021

Mokhtar, Maizura (author), Robu, Valentin (author), Flynn, David (author), Higgins, Ciaran (author), Whyte, Jim (author), Loughran, Caroline (author), Fulton, Fiona (author)The energy landscape for the Low-Voltage (LV) networks is undergoing rapid changes. These changes are driven by the increased penetration of distributed Low Carbon Technologies, both on the generation side (i.e. adoption of micro-renewables) and demand side (i.e. electric vehicle charging). The previously passive ‘fit-and-forget’ approach to...journal article 2021

Schweidtmann, A.M. (author), Weber, Jana M. (author), Wende, Christian (author), Netze, Linus (author), Mitsos, Alexander (author)Data-driven models are becoming increasingly popular in engineering, on their own or in combination with mechanistic models. Commonly, the trained models are subsequently used in model-based optimization of design and/or operation of processes. Thus, it is critical to ensure that data-driven models are not evaluated outside their validity...journal article 2021

Loeff, L. (author), Kerssemakers, J.W.J. (author), Joo, C. (author), Dekker, C. (author)Single-molecule techniques allow the visualization of the molecular dynamics of nucleic acids and proteins with high spatiotemporal resolution. Valuable kinetic information of biomolecules can be obtained when the discrete states within single-molecule time trajectories are determined. Here, we present a fast, automated, and bias-free step...journal article 2021

Andoni, Merlinda (author), Robu, Valentin (author), Couraud, Benoit (author), Früh, Wolf Gerrit (author), Norbu, Sonam (author), Flynn, David (author)With increasing decarbonisation and accessibility to our energy systems and markets, there is a need to understand and optimise the value proposition for different stakeholders. Game-theoretic models represent a promising approach to study strategic interactions between self-interested private energy system investors. In this work, we design...journal article 2021

(author)The rapid dynamics of COVID-19 calls for quick and effective tracking of virus transmission chains and early detection of outbreaks, especially in the “phase 2” of the pandemic, when lockdown and other restriction measures are progressively withdrawn, in order to avoid or minimize contagion resurgence. For this purpose, contact-tracing apps...journal article 2021

Proost, Rick (author)Monitoring software behaviour is being done in various ways. Log messages are being output by almost any kind of running software system. Therefore, learning how software behaves from doing analysis over log data can lead to new insights about the system. However, the number of log messages in a computer system grow fast, and analysing the log...master thesis 2020

Heijne, Yannick (author)Past research has successfully increased the accuracy and quality of horizontal wind speed measurements made by cup anemometers. Errors are introduced in a variety of ways: when operational conditions deviate from calibration, due to flow distortion and as a result of the mechanical properties of an instrument changing during its lifetime....master thesis 2020

Temizel, Irem Naz (author)This study defines who is at risk of automation and discusses policies to ensure the vulnerable groups are seen. The study of Nedelkoska and Quintini (2018) is taken as the role model: The risk of automation for individuals across OECD countries is calculated by associating the expert assessment conducted by Frey and Osborne (2013) with...master thesis 2020

Janssen, S.A.M. (author), van der Sommen, Régis (author), Dilweg, Alexander (author), Sharpanskykh, Alexei (author)Airport security checkpoints are the most important bottleneck in airport operations, but few studies aim to empirically understand them better. In this work we address this lack of data-driven quantitative analysis and insights about the security checkpoint process. To this end, we followed a total of 2277 passengers through the security...journal article 2020

Harms, Tim (author)Safety occurrences in the aviation industry are nowadays commonly regarded as the outcome of a complex system. Due to this systemic view on safety airlines pursue to understand this complex, underlying system and aim to proactively act upon the occurrence of these events. The most prevalent implementation of flight safety event detection is...master thesis 2020

Tollenaar, Veronica (author)Meteorites contain information on the formation and evolution of the Solar System. Antarctica is the most productive region for collecting meteorites, as the visually contrasting meteorites are easily detectable and tend to concentrate at specific areas exposing blue ice. Blue ice areas act as meteorite stranding surfaces (MSSs) if the flow of...master thesis 2020

Wang, Zili (author)An ideal road management system requires a real-time assessment of pavement performance. But there are many root causes of the status quo that the expectation and the system have not been achieved yet. One of them is the monitoring system. In the Netherlands, the measurement is carried out once a year because of the budget and also because it is...master thesis 2020

Olive, Xavier (author), Sun, Junzi (author)Instability in the movement of air masses in the atmosphere can result in turbulence. Most often, turbulence causes discomfort to passengers but it can occasionally affect their safety as well. Turbulence experienced by aircraft can be difficult to predict, especially for clear air turbulence (CAT) which occurs in the absence of any visual clues...conference paper 2020
