de Boer, Wouter (author)Autonomous robots are often successfully deployed in controlled environments. Operation in uncontrolled situations remains challenging; it is hypothesized that the detection of abstract discrete states (ADS) can improve operation in these circumstances. ADS are high-level system states that are not directly detectable and influence system...master thesis 2023

Wang, Hanyu (author), Chen, Dengkai (author), Huang, Y. (author), Zhang, Yahan (author), Qiao, Yidan (author), Xiao, Jianghao (author), Xie, Ning (author), Fan, Hao (author)This study aimed to enhance the real-time performance and accuracy of vigilance assessment by developing a hidden Markov model (HMM). Electrocardiogram (ECG) signals were collected and processed to remove noise and baseline drift. A group of 20 volunteers participated in the study. Their heart rate variability (HRV) was measured to train...journal article 2023

Wijnands, Ruben (author)In recent years, the increase in brain research led to the development of large-scale brain imaging techniques. With large-scale brain imaging techniques, such as functional magnetic resonance imaging (fMRI), functional connectivity analyses have shown altered connectivity patterns in humans and mice with neurobiological disorders, such as...master thesis 2022

Harleman, Bram (author)Research has shown that GLOSA systems can help reduce the emission of $CO_2$ by motor vehicles and improve flow on urban road networks. However, existing GLOSA systems only work in combination with a limited selection of Traffic Signal Controllers (TSCs) and therefore have not been widely implemented. This research describes and evaluates the...master thesis 2021

Clay, Thomas A. (author), Joo, RocĂo (author), Weimerskirch, Henri (author), Phillips, Richard A. (author), den Ouden, O.F.C. (author), Basille, Mathieu (author), Clusella-Trullas, Susana (author), Assink, Jelle D. (author), Patrick, Samantha C. (author)In a highly dynamic airspace, flying animals are predicted to adjust foraging behaviour to variable wind conditions to minimize movement costs. Sexual size dimorphism is widespread in wild animal populations, and for large soaring birds which rely on favourable winds for energy-efficient flight, differences in morphology, wing loading and...journal article 2020

Richa, Eduardo (author)The detection of unusual behavior plays a crucial role in the prevention of illegal and harmful activities such as smuggling, piracy, arms trading, human trafficking and illegal immigration. Also for military applications, it is useful to detect anomalous behavior to provide an alert for potential threats, especially with the more recent...master thesis 2018

van Santvoort, Sander (author)Hidden Markov models are suited for modelling processes whose state is not<br/>directly visible, but the outputs of which depend on its state. As such they can be used to model degradation of machines. Hidden semi Markov models extend hidden Markov models by removing the inherent geometric constraint imposed on hidden Markov models.<br/>Using...master thesis 2018

Janssen, Walter (author)In this MSc. thesis steady-state disaggregation methods for the Non-Intrusive Load Monitoring are researched. The main target is to find methods that have the potential to be practically applicable. These methods are characterized by the fact that they use data that is collected by smart meters, since smart meters are more and more the standard...master thesis 2018
