Kumaresan, A. (author), Kandasamy, N.K. (author), Kooij, R.E. (author)The endeavour towards making power distribution systems (PDSs) smarter has made the interdependence on communication network indispensable. Further, prospective high penetration of intermittent renewable energy sources in the form of distributed energy resources (DERs) has resulted in the necessity for smart controllers on such DERs. Inverters...article 2022

Keyvani Janbahan, A. (author), van der Veen, G. (author), Tamer, M.S. (author), Sadeghian Marnani, H. (author), Goosen, H. (author), van Keulen, F. (author)The real-time and accurate measurement of tip-sample interaction forces in Tapping Mode Atomic Force Microscopy (TM-AFM) is a remaining challenge. This obstruction fundamentally stems from the causality of the physical systems. Since the input of the dynamic systems propagates to the output with some delay, and multiple different inputs can...article 2020

Vugteveen, J. (author), de Bildt, A. (author), Serra, M. (author), de Wolff, M.S. (author), Timmerman, M.E. (author)This study assessed the factor structures of the Strengths and Difficulties Questionnaire (SDQ) adolescent and parent versions and their measurement invariance across settings in clinical (n = 4,053) and community (n = 962) samples of Dutch adolescents aged 12 to 17 years. Per SDQ version, confirmatory factor analyses were performed to assess...article 2020

Ligthart, J.A.J. (author), Ploeg, J. (author), Semsar-Kazerooni, E. (author), Fusco, M. (author), Nijmeijer, H. (author)Stability and string stability of platoons equipped with Cooperative Adaptive Cruise Control (CACC) is widely discussed in literature. However, safe behavior of a vehicle in a platoon, i.e., making sure that a vehicle is not involved in a collision with its preceding vehicle, is not considered to a large extent. This paper exploits techniques...article 2018

Smits, I.A.M. (author), Theunissen, M.H.C. (author), Reijneveld, S.A. (author), Nauta, M.H. (author), Timmerman, M.E. (author)The Strengths and Difficulties Questionnaire (SDQ) is a popular screening instrument for the detection of social-emotional and behavioral problems in children in community and clinical settings. To sensibly compare SDQ scores across these settings, the SDQ should measure psychosocial difficulties and strengths in the same way across community...article 2018

Keizer, W.P.M.N. (author)The impact of the array factor (AF) on the synthesis of a low-sidelobe taper for planar array antennas with a periodic element grid is investigated. A low-sidelobe taper that is synthesized for those far-field directions of the AF belonging to only visible direction, cosine u - v space, can seriously deteriorate with respect to peak sidelobe...article 2016

Calvert, S.C. (author), Snelder, M. (author), Taale, H. (author), van Wageningen-Kessels, F.L.M. (author), Hoogendoorn, S.P. (author)In this contribution a model-based analysis of the application of bounded acceleration in traffic flow is considered as a cause for the capacity drop. This is performed in a Lagrangian formulation of the kinematic wave model with general vehicle specific characteristics. Unconstrained overtaking is presumed, which allows a demonstration to be...conference paper 2015

Calvert, S. (author), Taale, H. (author), Snelder, M. (author), Hoogendoorn, S. (author)In this contribution a new model to include stochastic vehicle specific behaviour and interaction in traffic flow modelling is presented. The First Order Model with Stochastic Advection (FOMSA) is presented as a first order macroscopic kinematic wave model in a platoon-based Lagrangian coordinate system. The use of Lagrangian coordinates allows...conference paper 2015

Vrouwenvelder, A.C.W.M. (author)According to ISO 2394, structures shall be designed, constructed and maintained in such a way that they are suited for their use during the design working life in an economic way. To fulfil this requirement one needs insight into the risk and reliability under expected and non-expected actions. A key role in this respect is played by the...conference paper 2014

Zwart, H. (author), Firooznia, A. (author), Ploeg, J. (author), van de Wouw, N. (author)This paper considers the optimal control problem for a class of infinite-dimensional systems, namely spatially invariant systems. A common assumption in the scope of such optimal control problem is the exponential stabilizability of the infinite-dimensional plant. We propose sufficient conditions for the optimizability of spatially invariant...conference paper 2013

Ellens, W. (author), Kooij, R.E. (author)Network robustness research aims at finding a measure to quantify network robustness. Once such a measure has been established, we will be able to compare networks, to improve existing networks and to design new networks that are able to continue to perform well when it is subject to failures or attacks. In this paper we survey a large amount of...article 2013

Mouthaan, M.M. (author), van den Broek, S.P. (author), Hendriks, E.A. (author), Schwering, P.B.W. (author)We evaluate the performance of different key-point detectors and region descriptors when used for automatic classification of small sea targets in infrared video. In our earlier research performed on this subject as well as in other literature, many different region descriptors have been proposed. However, it is unclear which methods are most...article 2011

Weiss, M. (author)The problem of evaluating the performance of an uncertain guidance loop system is considered, when the uncertainty is described in terms of an integral quadratic constraint. The idea of the approach proposed in this paper is to determine the set of all possible state vector values at the end of the flight that are compatible with the model...conference paper 2010

Burghouts, G.J. (author), Geusebroek, J.M. (author), TNO Defensie en Veiligheid (author)For the modeling of materials, the mapping of image features onto a codebook of feature representatives receives extensive treatment. For reason of their generality and simplicity, filterbank outputs are commonly used as features. The MR8 filterbank of Varma and Zisserman is performing well in a recent evaluation. In this paper, we construct...article 2009

(author), TNO Informatie- en Communicatietechnologie (author)We present an algorithm that performs image-based queries within the domain of tree taxonomy. As such, it serves as an example relevant to many other potential applications within the field of biodiversity and photo-identification. Unsupervised matching results are produced through a chain of computer vision and image processing techniques,...article 2009

Toet, A. (author), Hogervorst, M.A. (author), TNO Defensie en Veiligheid (author)We developed a simple and fast lookup-table based method to derive and apply natural daylight colors to multi-band night-time images. The method deploys an optimal color transformation derived from a set of samples taken from a daytime color reference image. The colors in the resulting colorized multiband night-time images closely resemble the...conference paper 2008

TNO Defensie en Veiligheid (author), Eendebak, P.T. (author)In this article we study real 2-dimensional surfaces in the Grassmannian of 2-planes in a 4-dimensional vector space. These surfaces occur naturally as the fibers of jet bundles of partial differential equations. On the Grassmannian there is an invariant conformal quadratic form and we will use the structure induced by this quadratic form to...article 2008

TNO Fysisch en Elektronisch Laboratorium (author), Breuers, M. (author)The problem of estimating aircraft pose information from mono-ocular image data is considered using two different pose estimation algorithms. Both algorithms are based on the rotation invariant moment approach that was introduced by Dudani. The dependence of pose estimation accuracy on image resolution and aspect angle was investigated through...conference paper 1999
