Gupta, Siddharth (author)Rapid industrialization and use of carbon based fuels has caused a drastic increase in the atmospheric CO<sub>2</sub> levels in the last few decades. The rising anthropogenic CO<sub>2</sub> levels pose a significant threat to the environment as evidenced by the increase in the mean global temperature levels, and the rising ocean levels. To...master thesis 2020

Hosman, Tim (author)Electronic implants are becoming a valuable tool to explore and regulate neural activity, potentially overcoming neural disabilities that are still incurable. On the one hand, neural recording can provide tremendous insight into the neural system and the sometimes accompanied neural diseases. On the other hand, neural stimulation is necessary to...master thesis 2020

Vandecasteele, Kaat (author), De Cooman, Thomas (author), Dan, Jonathan (author), Cleeren, Evy (author), Van Huffel, Sabine (author), Hunyadi, Borbala (author), Van Paesschen, Wim (author)Objective: Seizure diaries kept by patients are unreliable. Automated electroencephalography (EEG)-based seizure detection systems are a useful support tool to objectively detect and register seizures during long-term video-EEG recording. However, this standard full scalp-EEG recording setup is of limited use outside the hospital, and a...journal article 2020

Hesam Mahmoudi Nezhad, N. (author), Ghaffarian Niasar, M. (author), Hagen, C.W. (author), Kruit, P. (author)In electron optics, the design of electron lens systems is still a challenge. To optimize such systems, the objective function which should be calculated, depends on the electric potential distribution in the space created by the lenses. To obtain the electric potential, the existing methods are generally based on some mathematical techniques...conference paper 2020

Sideris, Eva Ann (author), De Lange, Hendrik Cornelis (author), Hunt, A. (author)Microfluidic devices and micro-pumps are increasingly necessitated in many fields ranging from untethered soft robots, to pharmaceutical and biomedical technology. While realization of such devices is limited by miniaturization constraints of conventional actuators, these restrictions can be resolved by using smart material transducers...journal article 2020

Rajaei, H. (author), Haverkort, J.W. (author)A new compact electrode architecture with hollow pillar-shaped anodes and cathodes arranged in a ‘checkerboard’ pattern is analysed and shown to be equivalent to a particular arrangement of corrugated plate electrodes. Because all four sides of the flow channels are electrodes, this design takes up at least 1.5 to two times less volume...journal article 2020

Zhuo, M. (author), Grazioli, D. (author), Simone, A. (author)This study presents a three-dimensional computational model to evaluate effective conductivity and capacity of fiber-based battery electrodes. We employ electrodes composed of conductive and active material nanofibers dispersed in an electrolyte matrix. The effective conductivity is calculated by means of an equivalent resistor network model,...journal article 2020

Gevaert, Joost (author)Backward erosion piping is a dike failure mechanism. It is the internal erosion process by which sand is eroded away from underneath a dike or levee by seepage flow. This erosion process progresses in the direction opposite to the direction of seepage flow and forms a small pipe directly beneath the dike. As erosion continues, this process can...master thesis 2019

Abdul Madhar, S. (author), Mraz, Petr (author), Mor, A. R. (author), Ross, Robert (author)Partial discharge is a prevalent phenomenon under high voltage (HV) where the discharge partially bridges the gap between two electrodes. At increasing voltage levels, physical dimensions and distances between the electrical parts become critical. Designing electrical components for such high voltages and planning of high voltage laboratories...journal article 2019
