Gaete Cruz, M. (author), Ersoy, A. (author), Czischke, D.K. (author), van Bueren, Ellen (author)With the social, ecological and sanitary pressures on urban settlements<br/>and the public sector being unable to successfully provide such answers<br/>alone, co-design can play a crucial role towards urban transformations<br/>and resilient public spaces. We understand co-design as a process in<br/>which institutional networks of public, private...abstract 2021

Hussain, A.M. (author), Cattoor, B. (author), Hooimeijer, F.L. (author)Rapid urbanization and increasing globalization of urban development strategies are resulting in a lack of connection between people and places, and places and their context. Nevertheless, cultural embedding and sense of place have a direct impact on the quality of public space. The purpose of this research is to explore culture and context...abstract 2021

Atsma, Michael (author)In this thesis, we look at the traditional way of calculating a ship’s Power-Speed function using the Iterative Method, and then compare this to the renewed method created by Michaël Mersie, called the Direct Method. We find that, only under very specific circumstances, the Iterative Method can be slightly better at estimating the function of...bachelor thesis 2019

Sewnarain, Winay (author), Rijkeboer, Mats (author)At virtually every public venue, announcements for visitors are made via a public addressing system. It is important that announcements transmitted by means of a public addressing system are not only audible, but also well understood by the general public. This thesis covers one of three subsystems required to make<br/>a product that is capable...bachelor thesis 2019

Zoumis, Angelos (author)Cluster editing attempts to find the minimum number of edge additions and removals on an undirected graph, that will transform the graph to one consisting of only disconnected cliques. In this paper, we propose three heuristic approaches to this problem, based on algorithms used to solve different clustering problems. The algorithms were based...bachelor thesis 2021

van der Jagt, Thomas (author)A variation on the random Kuramoto model was analyzed, a mean-field model which describes the behavior of coupled oscillators in a random environment. The analytic results are based on the behavior of the system in the infinite volume limit. In the analysis critical values were found for the parameters in the model which can be used to determine...bachelor thesis 2017

Plămădeală, Ion (author)The wake effect which is turbulence behind a wind turbine created when it extracts energy negatively impacts the power output of the downstream turbines. Active Wake Control can mitigate this effect, by rotating some turbines away from the wind. Previous research applied single agent reinforcement learning to apply Active Wake Control, show- ing...bachelor thesis 2023

Groenendijk, Jurre (author)With the current state-of-the-art research, exporting a NeRF to a mesh has the side effect of having to evaluate a Multi Layer Perceptron at render-time, causing a significant decrease in performance. We have found a way to use K-Means clustering to pre-compute values for this MLP, storing them in multiple octahedron maps for the GPU to fetch...bachelor thesis 2023

van Breugel, Boris (author)This thesis focuses on electronic transport modelling in molecular junctions. The most common technique for modelling electron transport is the combination of Density Functional Theory (DFT) and Non-Equilibrium Green's Function's (NEGF). Conventional DFT+NEGF methods are, however, invalid for correctly modelling junctions under a bias voltage. ...bachelor thesis 2018

Meijssen, Vosse (author)In this bachelor thesis, the paper ”Classical synchronization indicates persistent entanglement in isolated quantum systems” by Dirk Witthaut et al. is looked into and discussed. First, synchronization in a classic sense is explained. The Kuramoto model is introduced, and a few properties of this model are defined. In the next part of the...bachelor thesis 2019

Wagenaar, Claire (author)In this thesis, several image segmentation techniques will be tested that eventually will be applied to MRI brain scans in order to detect hydrocephalus. The meth- ods include Sobel edge detection, Canny edge detection, active contour model (also known as snakes), k-means clustering and region growing. Furthermore two exten- sions are discussed....bachelor thesis 2020

Koene, Michael (author)Hydrothermal flames have become a very important field of study, especially for supercritical water oxidation. In supercritical water oxidation hazardous, toxic or non-biodegradable aqueous organic waste water streams can be efficiently destructed. Supercritical water oxidation takes place in a aqueous environment above the supercritical point....bachelor thesis 2018

van Burg, J.M. (author)This paper is a research on the segmentation of customers. The clustering of customers is done based on the variables recency, frequency and monetary value. Such a clustering is called an RFM-model. The clustering is done using the K-means clustering method. To find the optimal number of clusters the following performance metrics are used: Elbow...bachelor thesis 2020

Mulderij, Jesse (author)The study of the dynamics of large, complex networks is generally very hard. Analytical solutions are rarely available and numerical solutions require immense computation times. Recently, Gao et al. [1]have proposed a new theoretical approach to analyse the average behaviour of complex networks. In this research we discuss the derivation of the...bachelor thesis 2017

van Dongen, Lotte (author)The dynamics of interacting many-particle systems on quantum mechanical scale is a broad subject of research in modern physics. The understanding of the quantum correlations, or entanglement, between the particles in an isolated many-body quantum system may however be challenging, as the amount of interactions may be large. To be able to...bachelor thesis 2018

Giannakopoulos, G. (author), Perilla Guerra, A.D. (author), Rueda, José L. (author), Palensky, P. (author), Gonzalez-Longatt, Francisco (author)Modernization of power systems leads to more power electronic interfaced units in the generation, demand, and transmission. Examples are remotely installed renewable energy sources, loads with constant power, or high voltage direct current (HVDC) corridors. These changes significantly affect the frequency stability margins of the system and...book chapter 2023

Sun, B (author), Fan, Xuejun (author), Zhang, Kouchi (author)This chapter investigates the reliability of the integrated LED lamps with electrolytic capacitor-less LED drivers. Firstly, the impact of the interaction between the degradations of the LED light source and the driver on the lumen depreciation is studied. The electronic-thermal simulation was carried out to obtain the history of temperatures of...book chapter 2018

Hasnaoui, M. (author)The influence of Coriolis forces is studied under realistic conditions on a jet in atmospheric medium. Under the Boussinesq approximation, the relative thickness of the jet defines a small parameter in the flow. This parameter governs the asymptotic expansion of the analysis. Using a linear spectral approach, two-point closure correlation...conference paper 2006

Hematalikeikha, M.A. (author), Coolen, H.C.C.H. (author), Pourdeihimi, S. (author)Human activities based on human needs are affected by affordances and meanings that occur in the dwelling. Activities over time and space have meaningful sequences. The meaningfulness of activities in the cultural framework is conditioned by its special temporality and spatiality. Also, temporal or spatial sequences are the ways of separation or...conference paper 2014
