This thesis concerns the cap set problem in affine geometry. The problem is illustrated by the card game SET and its geometrical interpretation in ternary affine space. The maximal cardinality of a cap is known for the dimension one to six. For the four lowest dimensions, a maximal cap is constructed and the optimality of its size proven. From...

In this research computational fluid dynamics (CFD) is used to model a vertical axis wind turbine. Well known turbulence models | i.e. the k-epsilon and k-omega SST model | are used and compared in their performance against each other and a set of experimental data. The formal research question is "What models are available for the simulation of...

In open-pit mining on a bench level, the dig-limit optimization problem is deciding whether to classify a Selective Mining Unit(SMU) as waste or whether to classify it as ore. SMU’s with high ore grades are profitable for the mining operation, but due to equipment size a whole frame of SMU’s has to be classified as either ore or waste. In this...

In the noiseless case, the identification of a grey-box model can be posed as a feasibility problem, i.e. determining if existent - and if so - finding a parameter vector such that the parametric model equals the actual model (or its associated input-output data). Being that in this thesis we are interested in continuous-time grey-box...

The Netherlands policy on electricity steers towards a carbon neutral power generation in 2050. Among
the studies that focus on long term power system research, none use the starting point of a 100%
renewable power system in 2050. It is unknown if such a system is technically feasible given the
variability of wind and solar. The...

Target search in an obstacle filled environment is a practically relevant challenge in robotics that has a huge impact in the society. The wide range of applications include searching for victims in a search and rescue operation, detecting weeds in precision agriculture, patrolling borders for military and navy, automated census of endangered...

Hospitals need to be staffed around the clock to ensure satisfactory care for all patients. To this end, a set of shifts is defined which are assigned to nurses in a work schedule. The nurse rerostering problem (NRRP) occurs when due to unforeseen circumstances some shifts become unassigned: one or more nurses are no longer able to work some of...

A current trend in mining is towards lower grade deposits when easy to access mineral deposits are depleted in the world. Therefore, to make the current deposits accessible, a cost of mining need to be economic. Costs can be decreased in equipment and mine planning to maximize the availability and utilization of equipment for example by...

When sunlight illuminates a body, a tiny pressure is exerted upon its surface due to the photons impacting on it. Such a principle forms the basis of solar sailing, in which the solar radiation pressure is used to accelerate highly reflective lightweight structures called solar sails. Similarly, a laser-enhanced solar sail is a solar sail in...

The increasing interest in solar electric propulsion techniques, that enable significant propellant mass savings for a wide class of transfers, has brought about a revolution in the approach to trajectory design and optimization, as a result of the complexity and diversity of the problem. To date, solutions of different nature exist, but...

Electric Vehicles (EVs) provide a promising sustainable clean mode of transportation with much fewer emissions compared to the traditional Internal Combustion Engine (ICE) vehicles. However, this can only be considered true if the energy sources used for charging EVs are also from clean energy form. Various Renewable Energy Sources (RES) are...

The computation of complex turbulent flows design optimization processes is currently limited by the lack of accuracy of Reynolds-Averaged Navier-Stokes (RANS) in massively separated flows and the infeasible cost of multiple Large-Eddy Simulation (LES) evaluations. A novel method is presented, injecting data from LES or other high-fidelity...

Nigerian suffers from inadequate electricity supply of which her transmission capacity is a major factor. Having deregulated her power system recently , systems planning( generation and transmission) becomes a chicken and egg problem of which its coordination is a complex socio-technical issue. In an effort to approach this problem ,TEPES ( a...

This master thesis work is inspired by the practical aspects of the Analytical Constant Modulus Algorithm (ACMA) proposed by Alle-Jan van der Veen and Arogyaswami Paulraj. The ACMA deals with the beamforming problem associated with constant modulus co-channel signal interference in wireless communication. Co-channel interference occur when...

In this thesis work we solve the problem of optimal placement and sizing of distributed generation by using an original Fuzzy Adaptive Particle Swarm Optimization algorithm and a Mixed Integer Linear Programming formulation of the problem. The goal of integrating Fuzzy Logic in Particle Swarm Optimization is to be able to overcome some of the...

This thesis addresses synchromodal planning at operational level from the perspective of a logistics service provider. The existing infrastructure and the transportation activities are studied and modeled as an optimization problem with simultaneous vehicle routing and container-to-mode assignment. A special characteristic of this problem is the...
