Petrocco, R.P. (author)Video Streaming is nowadays the Internet’s biggest source of consumer traffic. Traditional content providers rely on centralised client-server model for distributing their video streaming content. The current generation is moving from being passive viewers, or content consumers, to active content producers, and the traditional content...doctoral thesis 2016

Katsimerou, C. (author)Affect-adaptive systems have the potential to assist users that experience systematically negative moods. This thesis aims at building a platform for predicting automatically a person’s mood from his/her visual expressions. The key word is mood, namely a relatively long-term, stable and diffused affective state, as opposed to the short-term,...doctoral thesis 2016

Heck, P.M. (author)The goal of this thesis was to obtain a deeper understanding of the notion of quality for Just-in-Time (JIT) Requirements. JIT requirements are the opposite of up-front requirements. JIT requirements are not analyzed or defined until they are needed meaning that development is allowed to begin with incomplete requirements. We started our...doctoral thesis 2016

Wilson, M. (author)This thesis presents research on scheduling in an uncertain environment, which forms a part of the rolling stock life cycle logistics applied research and development program funded by Dutch railway industry companies. The focus therefore lies on scheduling of maintenance operations on rolling stock in the railway industry. The first chapter...doctoral thesis 2016

De Laat, D. (author)In this thesis we develop techniques for solving problems in extremal geometry. We give an infinite dimensional generalization of moment techniques from polynomial optimization. We use this to construct semidefinite programming hierarchies for approximating optimal packing densities and ground state energies of particle systems. For this we...doctoral thesis 2016

Tsekmes, I.A. (author)The addition of microsized fillers to polymers, in order to tailor their properties, has been extensively used in many industrial applications since the 1960s. The same approach applies to the field of electrical insulation. Epoxy resin is a widely used polymer in the electrical power sector, but it is usually loaded with microsized fillers,...doctoral thesis 2016

Chepuri, S.P. (author)In today's society, we are flooded with massive volumes of data in the order of a billion gigabytes on a daily basis from pervasive sensors. It is becoming increasingly challenging to locally store and transport the acquired data to a central location for signal/data processing (i.e., for inference). To alleviate these problems, it is evident...doctoral thesis 2016

Setekera, R. (author)With the current increasing demand for faster and more reliable communication and computing electronic devices such as faster wireless communication networks, circuit designers are forced to carry out device optimization in order to achieve the maximum possible performance. To enable full circuit optimization, designers depend on compact models...doctoral thesis 2016

Poelma, R.H. (author)This thesis describes a series of experiments and fabrication methods on high-aspect-ratio 3D microstructures for wafer level packaging and 3D heterogeneous system integration (3D-HSI) using novel materials such as carbon nanotubes and thick-film photo-resists. Furthermore, theoretical and experimental research efforts are made to understand the...doctoral thesis 2016

Qi, L. (author)In this thesis, the research on silicon-based CMOS-compatible PureB technology was continued with the goal of enabling a PureB process module that could be added as a back-end module to wafers from a CMOS foundry. The properties of PureB layers deposited at low-temperature, particularly those deposited at 400°C were studied in more detail, among...doctoral thesis 2016

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

Raemaekers, S.B.A. (author)Third-party libraries are used frequently in modern software development. Websites that are visited millions of times a day often make heavy use of open-source software libraries. As a software developer, using these libraries has a number of advantages. Developers save time and effort because functionality does not have to be rebuilt from...doctoral thesis 2015

Qiu, Y. (author)Optimal flow control problems are important for applications in science and engineering. Solving such problems usually requires the solution of a large linear generalized saddle-point system. This linear system is sparse and highly indefinite. In order to solve such systems using Krylov subspace methods, efficient preconditioners are necessary...doctoral thesis 2015

Ngamkham, W. (author)Cochlear Implants (CIs) are prosthetic devices that restore hearing in profoundly deaf patients by bypassing the damaged parts of the inner ear and directly stimulating the remaining auditory nerve fibers in the cochlea with electrical pulses. This thesis describs the electronic circuit design of various modules for application in CIs in order...doctoral thesis 2015

Van Vroonhoven, C.P.L. (author)This thesis describes the theory, design and implementation of a new class of integrated temperature sensors, based on heat diffusion. In such sensors, temperature is sensed by measuring the time it takes for heat to diffuse through silicon. An on-chip thermal delay can be determined by geometry and the thermal diffusivity of silicon, and since...doctoral thesis 2015
