Zhu, Hongfei (author)Testing of protection schemes is important before it can be used for an actual topology. Nowadays, DC protection has not readily been designed and implemented in power systems. Therefore, due to high requirements on DC fault interruption, the designing and testing the corresponding DC protection with the use of a DC circuit breaker (DCCB)...master thesis 2019

Dooren, Mirja (author)Understanding the river dynamics is very important to be able to make use of all river functions and to protect ourselves against floods. Hydrodynamic models are used to predict river behaviour and one of the input parameters is the river geometry. In-situ measuring of river geometry can be very expensive and time consuming. Remote sensing...master thesis 2019

Kancharla, Varun (author)Cyclic loading tends to affect the strength and stiffness parameters of soils, degrade its structure and results in accumulation of the excess pore water pressure. Such behaviour often leads to premature failure of the soils. Over the past few decades, geotechnical research community has developed numerous constitutive models to predict the...master thesis 2019

Scherrenberg, Meike (author)The Greenland Ice Sheet is the world’s second largest ice sheet, storing an equivalent of 7.3 meters of sea level rise. Due to climate change, the Greenland ice sheet is currently losing mass at an accelerated rate. Ice sheet models are used to project long term melt of the ice sheet, which are often forced by output from climate models. Most of...master thesis 2019

Goyal, Jatinder (author)The gradually increasing air pollution calls for more and more effective solutions. This master thesis is focused on the investigation of aerosol trajectories inside the agricultural purifier named `ASPRA Agro', developed at VFA Solutions. Various CFD simulations have been carried out using an open-source C++ toolbox named `OpenFOAM'. The flow...master thesis 2019

Jacobs, Bas (author)Antenna design for Ka-band SAR systems used in earth observation missions is demanding for two reasons. A narrow beamshape results in a large aperture, and the frequency band dictates a short spacing between neighboring radiating elements. In our case, this leads to a requirement of more than a million radiating elements. In this thesis it is...master thesis 2019

Alderliesten, Earnest (author)Due to gas extraction, seismic activity has become a major problem in the province of Groningen. Existing buildings are not designed to withstand seismic loads and are likely to be structurally unsafe. Two storey terraced houses with concrete floors and large openings in the ground floor façade walls are onsidered vulnerable, since the in-plane...master thesis 2019

Anninga, Jordy (author)A Ball Balancing Robot (BBR) is a highly agile machine which is an unstable system. To stabilize, it uses three omni wheels connected to motors as an input of the system. Since it has less inputs than outputs, the BBR is an underactuated system. Due to the underactuated character and the non-minimum phase plant, the BBR is an interesting...master thesis 2019

van Eck, J.G.F. (author)Offshore wind energy is considered as a powerful form of renewable energy generation. It plays an important role in accelerating the world’s transition towards sustainable energy sources and reducing carbon emissions by fossil fuels. This study focuses on the advancement of service planning, related to this renewable energy source, by...master thesis 2019

Guijt, Arthur (author)In many real world scheduling problems there exist hard deadlines after which tasks can no longer be performed. Conversely, not all tasks are necessarily required to be scheduled. Furthermore, the problem investigated in this thesis includes sequence dependent setup times, an aspect reminiscent of the Travelling Salesperson problem. These...master thesis 2019

Stegman, Lars (author)District heating systems (DHS) are considered the best alternative to individual heat boilers as they have higher efficiency and enable the use of sustainable heat sources, like geothermal heat sources or waste heat from industry. Currently, most DHSs are operated by choosing a temperature once every day depending on the weather. This setting is...master thesis 2019

Dijkstra, Kevin (author)E8 is a famous root system in mathematics. Lisi claims in his paper “An Exceptionally Simple Theory of Everything” that there is a connection between the standard model of the elementary particles and this root system. He claims that standard model has the same structure as the root system E8. If this is true, there must be a mapping from the...bachelor thesis 2019

Benito Lazaro, Irene (author)The Philippines is a country located in the typhoon belt of the Pacific. Its location makes it typhoon prone and on average around 20 typhoons enter the country every year (Asian Disaster Reduction Center, 2008). This natural phenomenon can have disastrous effects and therefore, good preparedness is of special importance. Traditionally weather...master thesis 2019
