Subhedar, Nupur (author)Recently an oxidation and reduction cycle of metals has been proposed as alternative for liquid fuel combustion. Out of several possible metals iron is an interesting candidate because the oxide does not form making it more easy to develop a cyclic process. As a first building block towards a computation or particle dust clouds here a...master thesis 2017

Ketelaars, Martijn (author)During aircraft design,multiple tools are utilised to inspect the performance of the configuration. As the design matures, higher fidelity analyses are conducted to predict the flight dynamics of the aircraft. These analyses are conducted by using semi-empirical relations, numerically analysing flow behaviour, conducting wind-tunnel tests and...master thesis 2017

Jimenez Lluva, David (author)Electric Propulsion (EP) has become one of the most efficient technologies for spacecraft propulsion. In contrast to conventional chemical propulsion, the low thrust force generated by EP thrusters can deliver a momentum transfer to the spacecraft that is up to twenty times greater, for an equivalent propellant expenditure. Despite decades of...master thesis 2017

Liu, Riqian (author)There are two existing surface passivation principles. Passivation of unsaturated Si bonds is called chemical passivation. Surface passivation can also be achieved by shielding the minority charge carriers from the semiconductor interface by means of an electric field. This method is referred to as field-effect passivation. <br/>To test the...master thesis 2017

Bouazzata, Bilal (author), van der Kolk, Niels (author)In this thesis, a new RF Power Amplifier design is proposed that targets for improving the efficiency profile of classical RF Amplifiers. This RF Power Amplifier is especially designed for modulation schemes that need a PA with high PAPR. The PA consists of two different stages that will be digitally controlled. One of these stages has an...bachelor thesis 2017

Itraj, Mahesh (author)In a cordless kitchen system, the appliances do not make use of a power cord. The system consists of a power channel and a communication channel. There are various resonant topologies which can be implemented in the power channel[9]. The chosen topology should meet the functional as well as non-functional equirements of the system. Presently, a...master thesis 2017

Arts, Max (author)When offshore platforms have reached their end of lifetime, they have to be decommissioned. The topsides will be removed first, whereafter the jacket structure will be removed. Typically, the structure has to be removed up to 3 meters below seabed level. Decommissioning of jacket structures in clayey soils will result in large uplift forces due...master thesis 2017
