Appiah, Sevyllen (author)Resonant motions of a combined wind and wave concept (STC) in waves may induce significant loads in the structural components (such as wind turbine blades, nacelle or the interface between the spar and the torus). One type of resonant motions is related to the so-called Mathieu instability. For the STC under the survival mode where the torus is...master thesis 2017

Li, Ruyu (author)A driver with high power factor, high efficiency and safety isolation are more attractive in the lighting application. Flyback is an ideal choice to be the power factor stage in LED driver. But one of the most difficulty in flyback topology is the energy stored in its leakage inductance. This part of the energy will introduce very high voltage...master thesis 2017

Anggrit Dewangkara Yudha Pinangkis, Anggrit (author)Wireless data traffic is growing rapidly as the number of mobile devices increase and video contents become more popular. As 2.4\,GHz and 5\,GHz band communications only provide limited bandwidth, these frequency bands cannot support the demand of ultra-high data rate. Millimeter-wave (mmWave) communications promise massive available bandwidth...master thesis 2017

Ma, Yao (author)Selective oxidation behaviour of Fe-Mn-Cr steel alloys annealed at 950°C in Ar plus 5 vol.% H2 atmosphere under different annealing time and dew points was studied. The Fe-Mn-Cr steel alloys are externally oxidized when annealing at dew point of -45 °C, while internally oxidized at dew points of -10 and 10 °C. The internal oxides formed in the...master thesis 2017

van der Veer, Arlette (author)<br/>Airlines have a strong drive for innovation as there is a high risk of commoditization and new entrants. Mainly low cost carriers are an acute driver for process optimization and operational innovations. Additionally, the airline industry has a risk averse culture that comes with regulation which causes unavoidable innovation constraints....master thesis 2017

Kiakidis, Stamatis (author)The emerging field of 3D printing has expanded to the fabrication of metallic components during the last decade. Among the most prominent applications is the production of aluminium bronze marine propellers by the Wire+Arc Additive Manufacturing (WAAM) method. This method incorporates a welding system attached to a robotic arm. The final product...master thesis 2017

Harding, Jonas (author)In 2010 a large flash flood hit El Arish City, killing at least 6 people and causing a lot of damage. This was not the first time the Sinai was affected by these flash floods, more than 40 flash floods have been recorded in the El Arish watershed in the last 100 years. The...master thesis 2017

Khedoe, Prashant (author)Usually, oil fields are developed over three stages. First is the primary oil recovery, where the natural underground pressure is used to drive the oil to the surface. Afterwards is the secondary oil recovery, usually by water flooding or gas injection. However, the water flood yields lower sweep efficiency in heterogeneous reservoirs, contrary...bachelor thesis 2017

Aarden, Piet (author)Making offshore wind energy more cost competitive in comparison to fossil-fuel based production, is vital to maintain the direction the European Union has taken in renewable energy. Increasing the lifetime of a turbine can play a big role in driving down the overall costs of energy. The more energy the turbine is able to produce in its lifetime,...master thesis 2017

Dicker, Jeroen (author)Beach nourishments or sand replenishments are applied by the use of pipelines or the rainbow method. Replenished sand is then moved and levelled by bulldozers. This is a passive approach to process the outflow of material. The land based equipment is dependent from tides and water levels, and significant effort is required to install and...master thesis 2017

Rastogi, Divyam (author)Reinforcement Learning (RL) is a general purpose framework for designing controllers for non-linear systems. It tries to learn a controller (policy) by trial and error. This makes it highly suitable for systems which are difficult to control using conventional control methodologies, such as walking robots. Traditionally, RL has only been...master thesis 2017

Gorter, Wilbert (author)Allerlei diffusieverschijnselen in de natuurkunde kunnen omschreven worden<br/>met de Poissonvergelijking op een gebied met te kiezen randvoorwaarden. Er zijn echter ook verschijnselen waarin er een gelaagdheid optreedt zodat er in verticale<br/>richting minder makkelijk diffusie kan plaatsvinden. Dit leidt tot een vergelijking<br/>met...bachelor thesis 2017

Rosanka, Simon (author)Aviation activities contribute substantially to the anthropogenic climate impact. Due to an increasing demand on aviation transport, multiple mitigation strategies have been established to reduce the contribution to climate change by aviation. One promising strategy is to re-route aircraft, such that climate sensitive atmospheric areas are...master thesis 2017

Adhitomo Sulistyo, Adhitomo (author)One proposed method to delay the onset of gravity segregation between water and gas in enhanced oil and gas projects and extend the period of effective macroscopic sweep in “SWAG” is by separating the injection wells into two parallel horizontal wells (Stone, 2004). In this “modified SWAG”, the water injection well is aligned at a distance above...master thesis 2017
