Minderman, Björn (author)In the last decades our usage of the Radio Frequency (RF) spectrum has intensified a lot due to the increasing number of mobile devices. The spectrum is getting crowded and new communication alternatives might become necessary in the future. One such alternative is Visible Light Communication (VLC),which uses the visible light spectrum instead...master thesis 2023

Yuan, S. (author), Zhu, S. (author), Fioranelli, F. (author), Yarovoy, Alexander (author)The problem of estimating the 3D ego-motion velocity using multi-channel FMCW radar sensors has been studied. For the first time, the problem of ego-motion estimation is treated using radar raw signals. A robust algorithm using multi-channel FMCW radar sensors to instantly determine the complete 3D motion state of the ego-vehicle (i.e.,...journal article 2023

Rout, Samprajani (author), Monna, G.L.E. (author), Pareschi, Fabio (author), Setti, Gianluca (author), Serdijn, W.A. (author)The key challenges in designing a multi-channel biosignal acquisition system for an ambulatory or invasive medical application with a high channel count are reducing the power consumption, area consumption and the outgoing wire count. This article proposes a spread-spectrum modulated biosignal acquisition system using a shared amplifier and...journal article 2023

Fernandez-Menduina, Samuel (author), Krahmer, Felix (author), Leus, G.J.T. (author), Bhandari, Ayush (author)Conventional literature on array signal processing (ASP) is based on the "capture first, process" later philosophy and to this end, signal processing algorithms are typically decoupled from the hardware. This poses fundamental limitations because if the sensors result in information loss, the algorithms may no longer be able to achieve their...journal article 2022

Oud, Wessel (author)Water scarcity is an increasing problem around the world due to growing population and more frequent weather extremities. Desalination, the process in which salt water is converted into freshwater, is a sensible option to expand the drinking water supply by accessing the vast salt water resources on Earth. Capacitive deionization (CDI) is a...master thesis 2021

Ahmed, Sheeraz (author), Aubry, P.J. (author), Yarovoy, Alexander (author)In this paper, a novel multi-channel waveform agile radar testbed - ASTAP (Advanced Space-Time Adaptive Processing) with eight transmit channels and a single receive channel to form a co-located Multiple-Input Single-Output (MISO) radar is presented. Based on current configuration, the ASTAP radar system possesses agility for synthesizing and...conference paper 2021

Zhang, Jie (author), Chen, Huawei (author), Hendriks, R.C. (author)Multi-microphone speech enhancement methods typically require a reference position with respect to which the target signal is estimated. Often, this reference position is arbitrarily chosen as one of the reference microphones. However, it has been shown that the choice of the reference microphone can have a significant impact on the final...journal article 2020

Bouwmeester, A. (author)Banks and service companies in general are facing problems with multi-channel management, especially in the context of outbound communication. Problems are the high costs of the multi-channel systems, unsatisfied cus-tomers, and few customers who interact with companies. Personalization of the selection of communication channel to reach a...master thesis 2016

Wirianto, K. (author)Neural networks have been investigated by researchers for several decades. Microelectrodes and neural interfaces are used to obtain the information contained in the neuronal networks activity, which can be used to control neural prosthetic devices. This field has advanced rapidly and the current research is focusing on multi-channel...master thesis 2016

Weerens, L.M.E. (author)We redesigned the customer service system of NS Klantenservice, by analysing the organisational elements, processes and IT systems of the customer service department. The Axiomatic Design method is used to decoupled three dimensions that cause the current complexity in the operation. The dimensions of the contact channels, the core services...master thesis 2015

Simons, L.P.A. (author), Foerster, F. (author), Bruck, P.A. (author), Motiwalla, L. (author), Jonker, C.M. (author)Work place health support interventions can help support our aging work force, with mApps offering cost-effectiveness opportunities. Previous research shows that health support apps should offer users enough newness and relevance each time they are used. Otherwise the ‘eHealth law of attrition’ applies: 90 % of users are lost prematurely. Our...journal article 2015

Kalyanasundaram, P. (author)Wireless Body Area Network (WBAN) is used for communication among sensor nodes operating on, in or around the human body in order to monitor vital body parameters and movements. A typical sensor node in WBAN should ensure accurate sensing of the signal from the body, carry out low-level processing of the sensor signal, and wirelessly transmit...master thesis 2012

Menninga, L.H. (author)Many fields need high performance time measurements, including Single-Photon Avalanche Diode (SPAD) cameras, Positron Emission Tomography (PET) systems, and other time-of-flight systems. These measurements are often performed by means of time-to-digital converters, that for these applications, require high resolution, accuracy, and throughput....master thesis 2011

Cui, X. (author)Based on IEEE 802.15.4, ZigBee is developed for low-power and low-data-rate wireless communication and it is building up remarkable position for wireless sensor network (WSN). As ZigBee is using the 2.4GHz Industrial, Scientific, and Medical (ISM) unlicensed frequency band, coexistence issues arise as there are also other wireless technologies...master thesis 2009

Farazmand, Y. (author)Typically, in a wireless data network, all devices use the same channel (i.e. the same frequency) so that they can easily communicate with each other. However, as node density increases, the throughput share of each device decreases due to contention of the wireless medium. It seems that the capacity problem in wireless mesh networks can be...master thesis 2009

Simons, L.P.A. (author)The rise of Internet commerce led to multiple predictions of disintermediation and the decline of physical shopping. However, a "click and mortar" approach, which combines online, offline and telephone contact, has added value for customers and for supplier profitability, as recent research confirms. Our research objective was to help...doctoral thesis 2006
