Agbana, T.E. (author), Yang, H. (author), Soloviev, O.A. (author), Vdovin, Gleb (author), Verhaegen, M.H.G. (author)This paper presents experimental results of a static aberration control algorithm based on the linear relation be- tween mean square of the aberration gradient and the second moment of point spread function for the generation of control signal input for a deformable mirror (DM). Results presented in the work of Yang et al.1 suggested a good...conference paper 2016

Gonnissen, J. (author), De Backer, A. (author), den Dekker, A.J. (author), Sijbers, J. (author), Van Aert, S. (author)In the present paper, the optimal detector design is investigated for both detecting and locating light atoms from high resolution scanning transmission electron microscopy (HR STEM) images. The principles of detection theory are used to quantify the probability of error for the detection of light atoms from HR STEM images. To determine the...journal article 2016

Nanda, G. (author), Van Veldhoven, E. (author), Maas, D. (author), Sadeghian, H. (author), Alkemade, P.F.A. (author)The authors report the direct-write growth of hammerhead atomic force microscope(AFM) probes by He+beam induced deposition of platinum-carbon. In order to grow a thin nanoneedle on top of a conventional AFM probe, the authors move a focused He+beam during exposure to a PtC precursor gas. In the final growth stage, a perpendicular movement of the...journal article 2015

Chen, C. (author)The pervasiveness of the Internet and smartphones enables individuals to participate in online social networks such Twitter and Facebook, besides the classic physical contact network. Such multi-layer network allows for feedback between networks / layers. For instance, the spread of a biological disease such as Ebola in a physical contact...master thesis 2015

Van der Velde, O. (author)Over the years, glass has been increasingly used as a structural building material. Structural calculations on glass are conservative because the strength is quite uncertain. Weibull plots of the strength of glass can range from 20 MPa to 150 MPa. This is caused by flaws, which are not visibile to the human eye and therefore it is difficult to...master thesis 2015

Pérez Garza, H. (author), Ghatkesar, M.K. (author), Basak, S. (author), Löthman, P. (author), Staufer, U. (author)To manipulate liquid matter at the nanometer scale, we have developed a robotic assembly equipped with a hollow atomic force microscope (AFM) cantilever that can handle femtolitre volumes of liquid. The assembly consists of four independent robots, each sugar cube sized with four degrees of freedom. All robots are placed on a single platform...journal article 2015

Ghaemi, N. (author), Goverde, R.M.P. (author)This paper investigates the challenges of railway traffic controllers in dealing with big disruptions and the kind of support tools that could help to improve their task in terms of performance and lead time. The disruption handling process can be partitioned into three phases according to the bathtub model and to each phase the essential...conference paper 2015

Herfst, R. (author), Dekker, B. (author), Witvoet, G. (author), Crowcombe, W.E. (author), de Lange, D. (author), Sadeghian Marnani, H. (author)One of the major limitations in the speed of the atomic force microscope (AFM) is the bandwidth of the mechanical scanning stage, especially in the vertical (z) direction. According to the design principles of “light and stiff” and “static determinacy,” the bandwidth of the mechanical scanner is limited by the first eigenfrequency of the AFM...journal article 2015

(author)Mismatch between the refractive indexes of immersion media and glass coverslips introduces spherical aberrations in microscopes especially for high numerical aperture objectives. This contribution demonstrates an automated adjustment of the coverslip correction collar in scanning confocal microscopy to compensate for spherical aberrations due to...journal article 2014

Varotto, S.F. (author), Hoogendoorn, R.G. (author), Van Arem, B. (author), Hoogendoorn, S.P. (author)Automated driving potentially has a significant impact on traffic flow efficiency. Automated vehicles, which possess cooperative capabilities, are expected to reduce congestion levels for instance by increasing road capacity, by anticipating traffic conditions further downstream and also by accelerating the clearance of congestion. However, the...conference paper 2014

(author)The embryonic heart is already beating before cardiac morphogenesis is complete. Therefore, the effect of blood flow on cardiogenesis has been subject of many studies. Shear stress, acting on the endocardial cells, has been shown to alter the expression of shear-responsive genes implicated in heart development. The congenital heart defects (CHDs...journal article 2014

Marczaka, F. (author), Daamen, W. (author), Buisson, C (author)This paper presents an empirical analysis on lane changing behaviour using a trajectory data set collected at a weaving section in Grenoble (France). A detailed literature review shows that a strong empirical understanding of the weaving mechanisms is still lacking. This paper is devoted to fill this gap by investigating the lane changing...conference paper 2014

Goni Ros, B. (author), Knoop, V.L. (author), Van Arem, B. (author), Hoogendoorn, S.P. (author)Sags are freeway sections along which gradient changes significantly from downwards to upwards. Sags are often bottlenecks in freeway networks. Capacity decreases due to changes in car-following behavior. We present a microscopic traffic flow model that describes driving behavior and traffic flow dynamics at sags. The model includes a new...conference paper 2013

Morsink, D.W. (author)Nowadays both fluorescence and scanning electron microscopy are highly developed imaging techniques that are commonly used in many fields of research. As both techniques have their own strengths and weaknesses, a combination of both techniques can complement each other in certain fields of research. The combination of these two imaging...master thesis 2013
