Loor, Stephan (author)
In this thesis, two topics are studied: mathematical inequalities and non-linear quantum entanglement witnesses. First, various inequalities, like the Cauchy-Schwarz inequality (on finite dimensional vector spaces) and Jensen's inequality, along with their extensions and generalisations, are proved and discussed. The intimate relationship...

The numerical errors involving the application of the level-set method to a problem can be minimized by fitting a mesh (usually a triangular mesh in two dimensions) to the zero level-set curve defined by the level-set function. These numerical errors depend on two things: the size and skewness of the triangles in the mesh. To fit the mesh, Timo...

The research field of geometry processing is concerned with the representation, analysis, modeling, simulation and optimization of geometric data. In this thesis, we introduce novel techniques and efficient algorithms for problems in geometry processing, such as the modeling and simulation of elastic deformable objects, the design of tangential...

The competitiveness of the maritime sector together with energetic and environmental challenges have promoted a demand for more efficient marine vehicles. In response to this, research campaigns have been conducted, with the aim of developing new technologies. One of these technologies is the application of hydrofoils (e.g.: a Hull Vane) to...

The control of nitrite-oxidizing bacteria (NOB) challenges the implementation of partial nitritation and anammox (PN/A) processes under mainstream conditions. The aim of the present study was to understand how operating conditions impact microbial competition and the control of NOB in hybrid PN/A systems, where biofilm and flocs coexist. A...

One promising way to cope with changing requirements from the labor market in the domain of Science, Technology, Engineering and Mathematics (STEM), but also to keep the field up to date, to start innovations and to advance the STEM domain as such is the use of student labs. In these labs, students work together in small groups imitating...

Ferrofluid pocket bearings are a type of bearing that are able to carry a load using an air pocket encapsulated by a ferrofluid seal. Previously designed ferrofluid bearings show the great potential of the stick-slip-free and low viscous friction bearings, however until now the load capacity is limited. In this article a method is presented...

Petrus (Piet) Groeneboom was born in Scheveningen in 1941 and grew up in Voorburg. Both villages are located near The Hague in The Netherlands; Scheveningen actually being part of The Hague. He attended the gymnasium of the Huygens lyceum. In 1959, he entered the University of Amsterdam, where he studied psychology. After his “candidate” exam ...

Though the commercialisation of nanotechnology began only 30 years ago, it has developed into one of the fastest growing industries in terms of research and design, with an unlimited amount of possibilities that will transform industries from how we know them today. The advancement of nanotechnology relies on the actual production, control...

Ferrofluid bearings provide a cheap and passive alternative to contactless bearings such as magnetic bearings and fluid bearings. The absence of stick-slip and the low viscous friction make them interesting for high precision applications. Despite the theoretical models available in literature, the number of design rules for ferrofluid bearings...

Burn injuries can lead to serious complications that have a large influence on someone’s quality of life. In order to help patients, we need to gain insight into the wound healing process and in the development of complications that come with serious burn injuries. The final goal would be to prevent or at least reduce these complications. With a...

Parcel delivery companies offer time-guaranteed transportation of parcels, letters and packages, picked up at one customer and delivered at another. The time in which this has to be done depends on the service level that the customer pays for. To transport the parcels, a network is used consisting of facilities and links, where the facilities...

Characterization utilizing X-ray photoelectron spectroscopy (XPS) revealed the presence of all the expected elements found in trishydrazone hydrogels (3). Morphological study on confocal laser scanning microscopy (CLSM) and atomic force microscopy (AFM) revealed the branching and bundling of fibers that led hydrogels network as well as the...

In this study, a pressure filtration model for a slurry of milk fat crystal aggregates is developed, validated and used to investigate the effect of pressure-time profiles. The model focuses on the expression step and describes oil flow locally. The filter cake is modelled as a double porous non-linear elastic medium with permeabilities...

In this research project we investigate a variety of different approaches. A key element in our endeavour is the localising of points of interest (POI’s). These POI’s are the approximate centre points of the cells, the corners or vertices of the cells, and also the cell walls in given directions. Using these POI’s we have built some intuitive...

With increase in the number of sensors installed on sub-assemblies of industrial components, the amount of data collected is rapidly increasing. These data hold information in the areas of operation of the system and evolution of health condition of the components. Therefore, extracting the knowledge from the data can bring about significant...

Partial Differential Equations (PDEs) are a fundamental tool in modelling various physical phenomena. The lack of closed form solutions in most cases continues to provide a strong incentive to seek stable and consistent numerical methods. This report deals specifically with the mixed and hybrid nite element formulations; ideas that were...

BACKGROUND: Preferential crystallization is a common technique used in the purification of enantiomers, proving that crystallization may also be applied to the purification of very similar molecules by seeding the solution with the desired compound. Nonetheless, its application to other organic molecules is less widely documented in the...

Wireless power transfer systems, particularly those based on inductive coupling, provide an increasingly attractive method to safely deliver power to biomedical implants. Although there exists a large body of literature describing the design of inductive links, it generally focuses on single aspects of the design process. There is a variety...
