Hoekstra, Maxime (author)In this thesis max-plus algebra is introduced and applied to the problem of controlling train delays. Two control strategies for the propagation of delays are discussed. The first is by letting certain trains run faster when a delay is detected, the second is by breaking connections between trains that have to wait for each other in order to...bachelor thesis 2020

ter Meulen, Ruben (author)A random periodic two-dimensional spring network us built using a Poisson disk distribution and computing the Delaunay triangulation of the centers of the disks. The edges of the network represent springs that obey Hooke’s law with an adjustment on the spring constant. The adjustment allows spring to soften and to break. The two-dimensional...bachelor thesis 2019

Lumadjeng, Adia (author)For my bachelor’s graduation project, I did an internship at TNO, working on a project for the Ministry of Defence. This thesis describes and discusses the project that looked for a prediction model for the magnetic background field on a naval ship. The prediction model that was developed during this project separates the magnetic background...bachelor thesis 2017

Vooijs, Irene (author)Dit project behandelt de programmering en toepassing van een taxiservice, waarbij de passagiers zich vanaf of naar het treinstation willen verplaatsen. Met behulp van geheeltallig lineair programmeren wordt bepaald welke ritten door de taxi's moeten worden gereden, om de winst te maximaliseren. Dit model is gebaseerd op het model wat beschreven...bachelor thesis 2017

van de Kamp, Carsten T. (author)We consider adaptive network models with discrete and continuous state sets obeying dynamical rules that enable application to swarming systems. The 2-state adaptive network contains a supercritical pitchfork bifurcation in the transition between ordered and disordered stationary solutions. We derive an adaptive network model that works on a...bachelor thesis 2019

Zulkifli, Nur Amalina (author), Abdul Rahman, Alias (author), van Oosterom, Peter (author)This paper discusses 3D objects registration and modelling for cadastral objects within the Land Administration Domain Model (LADM) framework. A conceptual model as well as the associated technical model for the 2D and 3D objects have been proposed and developed for Malaysia. For both private and public land, the main subdivision of land in...conference paper 2014

Seetharam, S.C. (author), Kottititum, B (author), Maes, N. (author), Srinophakun, T. (author)Accelerated carbonation curing of cellulose fiber-cement composites is known to improve their durability in the form of decreased porosity and increased mechanical properties. In addition, because carbonation results in a decrease in the alkalinity of cement paste, it makes cement less aggressive towards the cellulose fibers. The properties of...conference paper 2021

Fusco, Daniela (author), Messali, F. (author), Rots, J.G. (author), Addessi, Daniela (author), Pampanin, Stefano (author)In recent years, the seismic risk in the north of the Netherlands has increased due to gas extraction. Since 2014, the Delft University of Technology started a research program to assess the seismic response of unreinforced masonry (URM) buildings. The Dutch URM buildings are characterized by slender piers and transverse walls. In common...conference paper 2021

Maas, J.B. (author), van Gent, R.N.H.W. (author), Hoekstra, J.M. (author)Object tracking is performed when surveillance applications have multiple observations of an object over time. An example of such a surveillance application is mounting a wideangle Frequency Modulated Continuous Wave (FMCW) radar system on board of a General Aviation aircraft. This is done in order to observe its environment in detail, including...conference paper 2018

(author), de Vries, M.E. (author), Ying, Shen (author)This paper proposes a discussion on opportunities offered by 3D visualization to improve the understanding and the analysis of cadastre data. It first introduce the rationale of having 3D visualization functionalities in the context of cadastre applications. Second the publication outline some basic concepts in 3D visualization. This section...conference paper 2018

Valle Torre, M. (author), Ye, Mengmeng (author), Lofi, C. (author)Effectively modelling and querying experience items like movies, books, or games in databases is challenging because these items are better described by their resulting user experience or perceived properties than by factual attributes. However, such information is often subjective, disputed, or unclear. Thus, social judgments like comments,...conference paper 2019

(author), Pain, Christopher (author)Numerical modelling has the potential to probe the complexity of the interacting physics of rubble mound armour systems. Through forward modelling of armour unit packs, stochastic variables such as unit displacement and maximum contact force per unit during an external oscillatory disturbance can be predicted. The combined finite-discrete...conference paper 2014

van Bilsen, Daniël (author), Huang, Yilin (author), Li, Fen (author)China is undergoing large changes to tackle carbon dioxide emissions and air pollution. While the top-down governance allows for clear setting of emission reduction targets for industrial sectors and major cities, reducing emissions in residential sectors in smaller (the so-called low-tier) cities remain challenging and often unaddressed.

Boricic, Aleksandar (author), Rueda, José L. (author), Popov, M. (author)Renewable energy sources (RES) penetrate power grids at all voltage levels. A large number of RES units are connected to medium-voltage (MV) and low-voltage (LV) levels resulting in a significant share of overall generation. Therefore, the dynamic behavior of such distribution grids should be thoroughly examined. The goal of this paper is to...conference paper 2020

Theocharis, A. (author), Popov, M. (author)In this paper, a piece-wise linearized transformer winding model is proposed for transient internal voltage distribution computations. In particular, the model is based on the linearization of the primitive non-linear, frequency dependent and invariant matrix of voltage distribution factors. This primitive matrix is utilized as a pattern from...conference paper 2019

Steinmann, Patrick (author), Wigman, S.B.J. (author)Between 2013 and 2015, over one million migrants entered Europe. Many European countries were unprepared for and overwhelmed by the rapidly unfolding, chaotic situation. To better handle future migration waves, and allow quicker exploration of government policy effects and interactions, a geospatial-based system dynamics model of migration flows...conference paper 2018

Van Wijngaarden-van Rossum, W.K. (author)Biogrout is a method to reinforce sand and gravel by the production of calcium carbonate. This calcium carbonate is produced using micro-organisms that are either present in the subsoil or injected into it. The micro-organisms are supplied with urea and calcium. Subsequently, they catalyse the hydrolysis of urea, by which carbonate is formed. In...doctoral thesis 2016

Van den Bergh, J. (author)Around 2004 the annual energy consumption of the Dutch (petro-)chemical industry was estimated to be 460 PJ of which 200 PJ could be allocated to separation processes [1]. In 2009, 15% of the global energy consumption was required for separation and purification processes to produce commodities. Moreover, it is expected that in 2040 the global...doctoral thesis 2010
