Ivashko, I. (author), Leus, G.J.T. (author), Yarovoy, Alexander (author)In this paper, we tackle the problem of selecting the radar node positions to provide an estimate of the target state vector with a prescribed accuracy. The topology optimization problem is formulated as selection of a fixed number of radar node positions from a set of available ones, where the radar observations are modeled by a general non...journal article 2017

Mahapatra, P.S. (author), van der Marel, H. (author), van Leijen, F.J. (author), Samiei Esfahany, S. (author), Klees, R. (author), Hanssen, R.F. (author)Deformation estimates from Interferometric Synthetic<br/>Aperture Radar (InSAR) are relative: they form a ‘free’<br/>network referred to an arbitrary datum, e.g. by assuming a reference<br/>point in the image to be stable. However, some applications<br/>require ‘absolute’ InSAR estimates, i.e. expressed in<br/>a well-defined terrestrial...journal article 2017

de Bruijn, J.A. (author), Janssen, M.F.W.H.A. (author)Cybersecurity is a global phenomenon representing a complex socio-technical challenge for governments, but requiring the involvement of individuals. Although cybersecurity is one of the most important challenges faced by governments today, the visibility and public awareness remains limited. Almost everybody has heard of cybersecurity,...journal article 2017

Heidary Shalmany, S. (author), Draxelmayr, Dieter (author), Makinwa, K.A.A. (author)This paper presents an integrated shunt-based current-sensing system (CSS) capable of handling ±36-A currents, the highest ever reported. It also achieves a 0.3% gain error and a 400-μA offset, which is significantly better than the state-of-the-art systems. The heart of the system is a robust 260-μ Ω shunt resistor made from the lead frame...journal article 2017

Stone, T.W. (author)Light pollution is a topic gaining importance and acceptance in environmental discourse. This concept provides a framework for categorizing the adverse effects of nighttime lighting, which advocacy groups and regulatory efforts are increasingly utilizing. However, the ethical significance of the concept has, thus far, received little critical...journal article 2017

Davis, D.J. (author), Jivet, I. (author), Kizilcec, René F. (author), Chen, G. (author), Hauff, C. (author), Houben, G.J.P.M. (author)Social comparison theory asserts that we establish our social and personal worth by comparing ourselves to others. In in-person learning environments, social comparison offers students critical feedback on how to behave and be successful. By contrast, online learning environments afford fewer social cues to facilitate social comparison. Can...conference paper 2017

Ivashko, I. (author)The ultimate goal of any sensing system is to build situation awareness. Existing<br/>solutions for a single radar node that have to assure extended areas of coverage with<br/>high resolution measurements (in range, cross-range, and Doppler) are physically<br/>cumbersome (large antenna size) and typically require large operational resources ...doctoral thesis 2016

Bossenbroek, B.M. (author)The current e-bike market is characterized by bike designs with conventional tubular frames, to which external components that allow electric cycling are attached. This often leads to a forced integration of the battery, motor and other components. Amsterdam based e-bike brand QWIC wanted to tackle this integration issue in a different manner,...master thesis 2016

Gevers, L.T.M. (author)Topology optimization is a bio-inspired optimization method based on the growth of bones. With this method, the optimal material distribution with the minimal amount of material for a product can be defined. This could help engineers to create innovative lightweight designs and get rid of benchmark and pervious design on which current designs...master thesis 2016

van Oostrum, Joep (author)During applied mechanics courses for undergraduates, the words `finite element' will be mentioned if a structural problem is so complex that it cannot be solved analytically or simply because it would require too much time to solve it by hand. The lecturer refers to a software package and explains how to work with it. Unfortunately, during these...bachelor thesis 2016

van Turnhout, J. (author)The dielectric spectra of colloidal systems often contain a typical low frequency dispersion, which usually remains unnoticed, because of the presence of strong conduction losses. The KK relations offer a means for converting ε′ into ε″ data. This allows us to calculate conduction free ε″ spectra in which the l.f. dispersion will show up...journal article 2016

Mariani, V. (author), Tanganelli, M. (author), Viti, S. (author), De Stefano, M. (author)It is well known that the axial load plays an important role in the evaluation of the structural capacity of RC columns. In existing buildings this problem can be even more significant than in new ones, since the material can easily present poor mechanical properties. The paper is aimed at the investigation of the role of the axial load...journal article 2016

Pourtalebi Hendehkhaleh, S. (author), Horvath, I. (author)The main assumption is that complicated systems, such as cyberphysical systems (CPSs), can be modelled by specific compositions of system manifestation features (SMFs). SMFs are regarded as architectural domains of a system having significance from an operational viewpoint. As system modelling entities, SMFs represent both physical and computing...journal article 2016

Fichtner, L.V.E. (author), Pieters, W. (author), Herdeiro Teixeira, A.M. (author)In the cybersecurity community it is common to think of security as a design feature for systems and infrastructures that may be difficult to balance with other requirements. What is less studied is how security requirements come about, for which reasons, and what their influence is on the actions the system facilitates. Security is for example...conference paper 2016

Islam, Tanvirul (author), Wehner, S.D.C. (author)An efficient implementation of many multiparty protocols for quantum networks requires that all the nodes in the network share a common reference frame. Establishing such a reference frame from scratch is especially challenging in an asynchronous network where network links might have arbitrary delays and the nodes do not share synchronised...journal article 2016

de Vries, G. (author)Low-carbon technologies are necessary to combat global warming. However, they are often opposed by members of the general public, causing costly delays and cancellations. In this article, I argue that language may be a relevant cause of such opposition. I introduce a theoretical model describing a boomerang effect in which positively framed...journal article 2016
