Zhang, Fengyan (author)Geometric algorithms are usually designed based on the assumption of using arbitraryprecision representations. However, in modern computer systems floating-point arithmetic and finite-precision approximation are often used as implementing exact computations would require large computational resources and would be rather slow in the applications....master thesis 2023

Generating consistent triangular terrain elevation data for noise modelling: Master thesis Geomaticsvan Rijssel, Laurens (author)In 2016, a collaboration between the TU Delft, RIVM and a few other companies started to automate the generation of environmental input data for noise modelling.<br/>As a part of that cooperation a promising triangle based data structure is researched to represent terrain elevation.<br/>Due to the properties of its generation it can provide...master thesis 2022

Goossens, Daan (author)Minimalistic, low-poly images have gotten more popular in recent years. But making these low-poly images by hand can be time intensive. For this reason, a lot of research has gone into how to triangulate an image (semi-)automatically. In previous works, only constant color and bilinear interpolation have been used to color the triangles in the...bachelor thesis 2021

van Opstal, W. (author)Navigational charts play a vital role in a ship's safety while navigating the seas, rivers or lakes. With most of the features and obstructions being out of sight -below sea-level - these charts are more critical than e.g. topographic maps. For routing but also positioning, depth information is a key aspect on these charts. This depth...master thesis 2020

Hoofwijk, Jorn (author)The aim of this research is to develop an N -dimensional adaptive sampling algorithm to efficiently sample functions, meaning that with fewer samples the same accuracy is achieved compared to what homogeneously spaced samples would achieve. This algorithm is based on an existing Python package called Adaptive. The developed algorithm is applied...bachelor thesis 2019

de Koster, Pascal (author)The material point method (MPM) is a numerical method for simulating ground deformations, that combinesthe benefits of a fixed grid with movingmaterial points, which carry the history dependent information of thecontinuum. During each time step, this information is projected to the grid, on which the equations of motionare solved and a...master thesis 2018

van der Molen, Hessel (author)Many robotic systems rely on laser ranging sensors to navigate and map their environment. As robots are getting more advanced, smaller and cheaper, their sensors need to decrease in size and cost, while increasing their reliability and accuracy. Current laser-based sensors have difficulty to meet these properties. They are either large,...master thesis 2017

Wang, Weijun (author)The finite-element method can easily handle complicated geometries because of the application of unstructured meshes. Unlike the Cartesian grid used in the finite-difference method, the unstructured mesh can follow the sharp interfaces that separate two layers of different properties. Therefore, the finite-element method can provide more...master thesis 2017

Jaspers, Ilja (author)We examine and prove the Borsuk-Ulam theorem and its combinatorial equivalent Fan's lemma. The theory of simplicial complexes and triangulations plays an important role in this. The Borsuk-Ulam theorem and Fan's lemma will be used to provide proofs for the Brouwer fixed point theorem and the combinatorial Sperner's lemma. Lastly the Borsuk-Ulam...bachelor thesis 2017

van der Peijl, I.V. (author)Multivariate simplex B-splines as a modelling technique provide more accurate models than standard polynomial models, which makes them an excellent modelling tool. Their coefficients, which are expressed in a barycentric coordinate system, are abstract. In this paper a physical transformation matrix is derived which can be applied to transform B...master thesis 2017

Indoor Signposting and Wayfinding through an Adaptation of the Dutch Cyclist Junction Network SystemMakri, A. (author)Finding one's way in complex indoor settings can be a quite stressful and time-consuming task, especially for users unfamiliar with the environment. There have been several different approaches to provide wayfinding assistance in order to guide a person from a starting point to a destination, ranging from traditional maps and signposting systems...master thesis 2015

Schmidt, F. (author)Supply chain management is ever-evolving. The supply chain of large shippers is constantly changing in response to external drivers. But which of these supply chain trends truly impact the air cargo industry and to what magnitude. This research identifies a number of supply chain trends based on an extensive literature review. After that, these...master thesis 2013

Peters, R.Y. (author)Depth-contours are an essential part of any hydrographic chart—a map of a waterbody intended for safe ship navigation. Traditionally these were manually drawn by skilled hydrographers from a limited set of surveyed depth measurements. Nowadays this process of map making is shifted towards the digital domain, not in the last place because of the...master thesis 2012

Daniel Swakman, L. (author)The european quarter in Brussels has become a monofunctional office district since the rapid development of the European Union in the second half of the twentieth century. Uncontrolled office expansion has led to a district characterised by the monotony of glass closed office blocks, empty streets and large infrastructure. This project is a...master thesis 2011

Arroyo Ohori, G.A.K. (author)Planar partitions (subdivisions of the plane into polygonal areas) constitute one of the most important data representations in GIS. They are used to model concepts as varied as land use, administrative units, natural features and cadastral parcels, among many others. However, since polygons are often stored separately, different errors and...master thesis 2010

Schaap, T.M. (author), Scheele, B.R.V. (author)At the University of Chile, prof. dr. N. Hitschfeld Kahler is conducting research on the automatic generation of meshes in both 2D- and 3D-environments based on images or 3D-models. At the moment she is researching the analysis of images of tree stems by generating 2D meshes of triangles (triangulations) over the image and retrieving data based...bachelor thesis 2008
