Hosseini, S. Ali (author), Tavazoei, Mohammad Saleh (author), Van Eijk, Luke F. (author), Hassan HosseinNia, S. (author)The Hybrid Integrator-Gain System (HIGS) has recently gained a lot of attention in control of precision motion systems. HIGS is a nonlinear low pass filter/integrator with a 52° phase advantage over its linear counterpart. This property allows us to avoid the limitations typically associated with linear controllers, like the waterbed effect...conference paper 2022

Van Eijk, Rob (author), Asghari, H. (author), Winter, Philipp (author), Narayanan, Arvind (author)The web is global, but privacy laws differ by country. Which set of privacy rules do websites follow? We empirically study this question by detecting and analyzing cookie notices in an automated way. We crawl 1,500 European, American,and Canadian websites from each of 18 countries. We detect cookie notices on 40% of websites in our sample. We...conference paper 2019

Asghari, H. (author), Van Eeten, M.J.G. (author), Arnbak, A.M. (author), Van Eijk, N.A.N.M. (author)Even though we increasingly rely on HTTPS to secure Internet communications, several landmark incidents in recent years have illustrated that its security is deeply flawed. We present an extensive multi-disciplinary analysis that examines how the systemic vulnerabilities of the HTTPS authentication model could be addressed. We conceptualize the...report 2013

Van Eijk, G. (author)Does the neighbourhood in which people live matter for the resourcefulness of their personal network and thus for their opportunities in life? Do residents of a multi-ethnic ‘problem’ area maintain fewer relationships with fellow-residents compared to residents of a homogeneous problem-free neighbourhood? And do ‘diversity-seekers’ who choose to...doctoral thesis 2010

Vonck, D. (author), Goossens, R.H.M. (author), Van Eijk, D.J. (author), De Hingh, I.H.J.T. (author), Jakimowicz, J.J. (author)Background- Laparoscopic surgery requires specially designed instruments. Bowel tissue damage is considered one of the most serious forms of lesion, specifically perforation of the bowel. Methods - An experimental setting was used to manipulate healthy pig bowel tissue via two vacuum instruments. During the experiments, two simple manipulations...journal article 2010

Van der Laan, D.J. (author), Schaart, D.R. (author), Maas, M.C. (author), Beekman, F.J. (author), Bruyndonckx, P. (author), Van Eijk, C.W.E. (author)Much research is being conducted on position-sensitive scintillation detectors for medical imaging, particularly for emission tomography. Monte Carlo simulations play an essential role in many of these research activities. As the scintillation process, the transport of scintillation photons through the crystal(s), and the conversion of these...journal article 2010

(author)A two-dimensional position-sensitive dosimetry system based on a scintillating gas detector is being developed for pre-treatment verification of dose distributions in particle therapy. The dosimetry system consists of a chamber filled with an Ar/CF4 scintillating gas mixture, inside which two gas electron multiplier (GEM) structures are mounted ...journal article 2009

Van Eijk, G. (author)This paper examines whether and how neighbourhood composition is connected to, and has impact on relationships and social capital. Three debates in urban sociology engage with this question: studies on poverty neighbourhoods, on gentrification and on gated communities. These debates reveal that in order to understand how spatial segregation...conference paper 2009

Venstra, W.J. (author), Spronck, J.W. (author), Sarro, P.M. (author), Van Eijk, J. (author)Photolithography on high topography substrates, such as the sidewalls or the bottom of cavities and trenches created by bulk micromachining, enables the design of complex three-dimensional structures. When a contact lithography system is used to pattern such substrates, local gaps exist between the mask and the substrate. In this paper we...journal article 2009

Van Eijk, G. (author)This paper examines people’s perceptions of class and class differences—in general and with regard to personal relationships. Data from an original survey on personal networks (n=195) shows that most people think they are middle class, although many lower class respondents classify themselves as working class. In addition, according to...conference paper 2009

Clarijs, M.C. (author), Bom, V.R. (author), Van Eijk, C.W.E. (author)Neutron resonance capture analysis (NRCA) is a method used to determine the bulk composition of various kinds of objects and materials. It is based on analyzing direct capture resonance peaks. However, the analysis is complicated by scattering followed by capture effects in the object itself. These effects depend on the object’s shape and size....journal article 2009

(author)We developed positron emission tomography (PET) detectors based on monolithic scintillation crystals and position-sensitive light sensors. Intrinsic depth-of-interaction (DOI) correction is achieved by deriving the entry points of annihilation photons on the front surface of the crystal from the light sensor signals. Here we characterize the...journal article 2009

Wauben, L.S.G.L. (author), Goossens, R.H.M. (author), Van Eijk, D.J. (author), Lange, J.F. (author)Background: Iatrogenic bile duct injury remains a current complication of laparoscopic cholecystectomy. One uniform and standardized protocol, based on the ‘‘critical view of safety’’ concept of Strasberg, should reduce the incidence of this complication. Furthermore, owing to the rapid development of minimally invasive surgery, technicians are...journal article 2008
