Mohammad Zaki, A.R. (author), Nihtianova, S. (author)Small charge detection is used for a wide range of applications: advanced industrial process control, experimental physics and space instruments, and material testing and medical imaging. These applications give rise to the development of a wide variety of charge-sensitive readout integrated circuits (ROICs). The trend in the state-of-the-art...conference paper 2023

Andreadis, Kostas (author)The last few years have shown promising developments in single-molecule protein sequencing using a biological nanopore. Using only one membrane pore in a salt buffer, an applied potential creates a measurable ion current through the pore’s constriction. If a small molecule passes through the pore, this disruption is visible as a characteristic...bachelor thesis 2022

Mohammad Zaki, A.R. (author), Nihtianova, S. (author)This article presents the experimentally characterized performance of a low noise and wideband sensor readout integrated circuit (ROIC). The ROIC is designed to detect small amounts of charge generated by a silicon p-i-n detector as a result of particle detection, with very high time resolution and limited power consumption. The architecture...journal article 2022

Hamo, Alan (author), van der Spijk, Tim (author)The amount of people dealing with dementia is rising globally. The amount of caretakers is, however, not. Therefore, technological aids are needed to support people dealing with dementia and relieve the stress on their caretakers. Current solutions provide tracking of people with dementia. Also, different robots exist that provide people with...bachelor thesis 2021

Diouf, C.E.V. (author), Janssen, G.J.M. (author), Dun, H. (author), Kazaz, T. (author), Tiberius, C.C.J.M. (author)For validation and demonstration of high accuracy ranging and positioning algorithms and systems, a wideband radio signal generation and acquisition testbed, tightly synchronized in time and frequency, is needed. The development of such a testbed requires solutions to several challenges. Tight time and frequency synchronization, derived from...journal article 2021

Bosch, Rayen (author)Climate mitigation measures are integrated in various governmental and commercial initiatives. The sector of electrification and energy is no exception to this. For remote island communities however, the access to reliable and affordable electricity comes with additional difficulties. The effects of climate change, energy dependency and...master thesis 2019

Rebers, Marjolein (author), Breysens, G. (author)The goal of this bachelor thesis is to develop a control system that controls the temperature of a microthruster. This system also needs to acquire data for research. The microthruster contains a resistor that is used both as a heater and as a sensor. To facilitate the acquisition of data and the testing of the control system, a lab setup with a...bachelor thesis 2019

Bhoera, Ramkoemar (author)Global AIS coverage is not possible with terrestrial AIS as base stations are required to be build on sea, which is impractical. With the use of LEO satellites, the field of view of a single receiver is increased and is capable of communicating with many AIS cells simultaneously. As many vessels are transmitting data to the same receiver,...master thesis 2019

Manolova, Manuela (author)In recent years, there has been a growing necessity for 3D geoinformation in urban planning and infrastructure management to provide a more realistic representation of urban areas and the built environment. A key concept in public infrastructure management is Life Cycle Asset Management (LCAM), which aims to improve the decision making in each...master thesis 2018

Wigman, Stefan (author)This study approached migration-related problems from a global perspective. The inter- connected nature of migration means that migration problems accumulate and intensify throughout the world. To capture these effects, a data-rich model component was devel- oped for global migration dynamics.<br/>To that extent, this study has developed the...master thesis 2018

Pribic, Radmila (author), Leus, G.J.T. (author), Tzotzadinis, C. (author)Data acquisition in compressive sensing (CS) is commonly believed to be less complicated, and even less costly, while performing agreeably. There is a major lack of measureable foundations supporting this optimism as the performance and complexity of a CS sensor have hardly been quantified. We aim to fill the gap by computing the performance...conference paper 2018

Wolszczak, W.W. (author), Dorenbos, P. (author)In this article we present a method of characterizing scintillating materials by digitization of each individual scintillation pulse followed by digital signal processing. With this technique it is possible to measure the pulse shape and the energy of an absorbed gamma photon on an event-by-event basis. In contrast to time-correlated single...journal article 2018

TZOTZADINIS, Chris (author)Compressive Sensing (CS) provides a new paradigm in data acquisition and signal processing based on the assumption of sparsity and the incoherence of the received signal. Based on that concept, many radar front-end architectures have been studied with the implementation of CS. In these architectures, less data are collected but the radar scene...master thesis 2017

Ishiyama, T. (author)Surface waves in seismic data are often dominant and mask primaries in land or shallow-water environments. Separating them from the primaries is of great importance either for removing them as noise for reservoir imaging and characterization, or for considering them as signal for near-surface characterization. However, their complex properties,...doctoral thesis 2015

Mahdad, A. (author), Doulgeris, P. (author), Blacquiere, G. (author)Seismic acquisition is a trade-off between economy and quality. In conventional acquisition the time intervals between successive records are large enough to avoid interference in time. To obtain an efficient survey, the spatial source sampling is therefore often (too) large. However, in blending, or simultaneous acquisition, temporal overlap...journal article 2011
