(author), Gelinck, G.H. (author)A monolithic manufacturing process is presented for the realization of active-matrix meshed thin-film-transistor (TFT) arrays on foil with physical voids between pixels, realizing membrane-like electronic arrays. The process is scalable to large-area substrates and enables (improved performance of) biometrics-under-display applications. Moreover...article 2021

Alrushud, K.M. (author), Gomez-Guillamon Buendia, V.A. (author), Podilchak, S.K. (author)A planar quasi-endfire surface-wave antenna (SWA) using substrate integrated waveguide (SIW) technology for integration with CubeSats and other small satellites is proposed in this letter. This antenna can be attached to the body of the satellite, resulting in a compact and low-cost design. A quasi-endfire beam pattern is achieved by the...article 2021

Maljaars, J. (author), Bonet, E. (author), Pijpers, P.J.M. (author)Steel orthotropic decks in bridges and ferries have shown to be prone to fatigue cracking. A typical fatigue crack observed in these structures initiates at the root of the weld between the deck plate and stringer and grows into the deck plate. Due to limited fatigue test data available and the deviating characteristics of this type of crack as...article 2018

Haag, S.R. (author), Hoogeland, M.G. (author), Vredeveldt, A.W. (author)Instantaneous insight into the structural damage sustained by a ship running aground, can be of great aid in the decision making following such a disaster. It should be possible to distil the extent of structural damage from acceleration measurement data of the entire vessel. Such measurements could possibly even be done using a simple...conference paper 2017

Berkhoff, A. (author), Tajdari, F. (author)This paper presents a method to realize an acoustic source for low frequencies with relatively small thickness. A honeycomb plate structure which is open on one side combines the radiating surface and the major part of the air cavity. The vibration of the plate is controlled with a decentralized feedback controller. The fundamental resonance...conference paper 2017

Scheperboer, I.C. (author), Efthymiou, E. (author), Maljaars, J. (author)This paper considers local buckling of perforated square aluminium plates. Plates of various slenderness with simply supported edges and subjected to uniaxial compression are studied using the finite element method. Different perforation patterns are investigated, from a single circular hole to 25 circular holes distributed over the plate. A...article 2016

Scheperboer, I. (author), Efthymiou, E. (author), Maljaars, J. (author)Aluminium plates containing a single hole or multiple holes in a row are recently becoming very popular among architects and consultant engineers in many constructional applications, due to their reduced weight, as well as facilitating ventilation and light penetration of the buildings. However, there are still uncertainties concerning their...conference paper 2016

Sunil, A.B. (author), Erkiny, Z. (author), Veugenyz, T. (author)License plate matching plays an important role in applications like law enforcement, traffic management and road pricing, where the plate is first recognized and then compared to a database of authorized vehicle registration plates. Unfortunately, there are several privacy related issues that should be taken care of before deploying plate...conference paper 2016

(author)The intra-plate deformation of the Upper Rhine Graben (URG) located in Central Europe is investigated using geodetic measurement techniques. We present a new approach to calculate a combined velocity field from InSAR, levelling and GNSS measurements. As the expected tectonic movements in the URG area are small (less than 1mma−1), the best...article 2015

(author)Rail dampers and sound absorbing plates have been tested on a high speed railway slab track in a walled cutting at a noise sensitive location. Their noise reduction has been determined from pass-by measurements during service and predicted using BEM calculations. The cutting depth, noise barrier height and configuration vary along the length of...conference paper 2015

Volatier, J.B.C.G. (author), Baümer, S.M.B. (author), Kruizinga, B. (author), Vink, H.J.P. (author)Designing a novel optical system is a nested iterative process. The optimization loop, from a starting point to final system is already mostly automated. However this loop is part of a wider loop which is not. This wider loop starts with an optical specification and ends with a manufacturability assessment. When designing a new spectrometer with...conference paper 2014

Maljaars, J. (author), Pijpers, R.J.M. (author)A number of orthotropic deck structures of existing bridges are suffering from fatigue cracks. Maintenance of these deck structures may consist of regular inspections and repair of detected cracks. The usual fatigue design life procedure for aswelded structures based on S-N curves is not feasible for determining the remaining fatigue life after...conference paper 2013
