Gootjes, Didier (author)Small-scale 3D-printing has become a common appearance. Today there are many companies specialized in selling and designing small-scale 3D-printers . Applications range from creating custom-made toys to creating spare parts for the 3D-printer itself as well as medical applications such as skull parts, knee replacements and hip replacements. The...master thesis 2017

Manzoor, Qasim (author)The Blade Element Momentum (BEM) method is a widely used model for rotor performance and aeroelastic calculations but it has assumptions in its formulation which limit its accuracy. The theoretical background of these limitations has been studied and an improvement in the form of the Near Wake Model (NWM) has been identified. The model adds near...master thesis 2017

Rivera Arreba, Irene (author)Floating wind turbines (FWTs) are proposed as a method to harness the significant wind energy resource in deep water. International research efforts have led to the development of coupled numerical global analysis tools for FWTs in order to understand their behavior under wind and wave actions. The hydrodynamic models in such tools are typically...master thesis 2017

Hinkofer, Thomas (author)With an increased demand for renewable energy sources, geothermal developments have moved into the spotlight, including sedimentary structures. In the western part of the Netherlands, cretaceous sandstone bodies are already in use for the geothermal energy production. However, these reservoirs are generally producing water at temperatures less...master thesis 2017

Smeets, Martijn (author)As part of the ESA mission to Jupiter and Ganymede carried out by the Jupiter Icy Moons Explorer (JUICE) spacecraft, the Ganymede Laser Altimeter (GALA) will determine the topography and detect Ganymede’s tidal degree-2 signal in order to investigate the existence of a subsurface ocean and constrain its thickness. To deliver successful...master thesis 2017

Aramburo Velez, Daniel (author)The Dutch Government is aiming for a CO2 neutral energy supply in 2050; this requires a transition from using energy from fossil fuels to using renewable energy sources. Decline in oil production in the Netherlands occurs in an epoch with an increased interest in geothermal heat production as an alternative source of energy. In the present study...master thesis 2017

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
