Bronkhorst, A.J. (author), Moretti, D. (author), Geurts, C.P.W. (author)This paper describes the application of the Frequency Domain Decomposition (FDD) technique on measured acceleration data on the residential tower New Orleans in Rotterdam, the Netherlands. The goal of this study is to determine and analyse multiple natural frequencies and mode shapes of this tower. A measurement campaign was setup on the 158 m...conference paper 2023

Xiao, C. (author), Leeuwenburgh, O. (author), Lin, H.X. (author), Heemink, A. (author)A reduced order modeling algorithm for the estimation of space varying parameter patterns in numerical models is proposed. In this approach domain decomposition is applied to construct separate approximations to the numerical model in every subdomain. We introduce a new local parameterization that decouples the computational cost of the...article 2021

Buijs, R.D. (author), Schilder, N.J. (author), Wolterink, T.A.W. (author), Gerini, G. (author), Femius Koenderink, A. (author), Verhagen, E. (author)We investigate how partial knowledge of scattering nanostructures enables extraction of spatial information from far-field radiation patterns. A reconstruction technique based on singular value decomposition allows localisation of a point-like light source with nanoscale resolution.conference paper 2020

Pairon, T. (author), Karki, S. (author), Monni, S. (author), Craeye, C. (author)A fully metallic monopole element is proposed for satellite SAR antennas. This element has significant gain in the broadside direction thanks to its curved arm. This element is then studied in a large sparse array. A fast analysis technique is presented in order to solve for the currents of few hundreds elements, which correspond approximately...conference paper 2019

Romijn, T.C.J. (author), Pham, T.H. (author), Wilkins, S. (author)In this paper, a modular equivalent consumption minimization strategy (ECMS) framework for hybrid vehicles is proposed. The approach is based on applying the dual decomposition to the ECMS optimal control problem. This allows the optimal control problem to be decomposed into smaller optimization problems related to each of the subsystems, for...conference paper 2019

Bastiaansen, H.J.M. (author), Lazovik, E. (author), den Breejen, E. (author), Broek, J. (author)Maritime autonomous and unmanned shipping have considerable potential for cost-effective and safe cargo or passenger transport and other maritime operations. Such a manner of shipping will introduce operations chains with new roles and responsibilities. Widescale adoption requires an agreed upon overarching business process framework and...conference paper 2019

Seykens, X. (author), van den Tillaart, E. (author), Lilova, V. (author), Nakatani, S. (author)Since the introduction of Euro IV legislation [1, 2], Selective Catalytic Reduction (SCR) technology using liquid urea injection is (one of) the primary methods for NOx reduction in many applications. Ammonia (NH3) is the reagent and key element for the SCR system and its control calibration to meet all operational requirements. TNO and Horiba...article 2016

Veugen, P.J.M. (author)In the field of signal processing in the encrypted domain, linear operations are usually easy to perform, whereas multiplications, and bitwise operations like comparison, are more costly in terms of computation and communication. These bitwise operations frequently require a decomposition of the secret value into bits. To minimize the...article 2015

de Wit, J.J.M. (author), Harmanny, R.I.A. (author), Molchanov, P. (author)Abstract—The micro-Doppler spectrogram depends on parts of a target moving and rotating in addition to the main body motion (e.g., spinning rotor blades) and is thus characteristic for the type of target. In this study, the micro-Doppler spectrogram is exploited to distinguish between birds and small unmanned aerial vehicles (UAVs). The focus...conference paper 2014
