de Groot, O. (author), Salentijn, J. (author)The quality of audio amplifiers used in Hi-Fi sound installations is largely determined by the distortion of the output signal. This report proposes a method of improving the distortion reduction in audio amplifiers by using a topology with active feedback. The characteristics of the standard non-inverting amplifier are extended to this new...bachelor thesis 2016

Bentvelsen, R. (author), Emmer, K. (author)New research on the impact of home batteries, such as the Tesla Powerwall, on the electricity grid needs photovoltaic emulators, enabling to test independent of weather conditions. However, current PV emulators give little flexibility, are hard to implement, or very expensive. Current models are mostly focused on qualitative analysis, and not so...bachelor thesis 2016

Kunkels, L.B. (author), Belier, J.H. (author)This study is done as part of creating a groundwater-analyzing sensor system. This thesis elaborates on finding a cost-efficient way of implementing a telecommunications channel between a measuring node and a data-server, together with forming an energy-efficient power supply system that powers a system over a cable of 60metres. The cellular...bachelor thesis 2016

Van Remundt, M. (author), Witte, T. (author)This thesis describes the work of two students who designed the control system of a stand-alone water well measuring system, named SubDowser. The project was done by order of a proposal from the start-up company SkyDowser. The total thesis group, consisting of three subgroups, was asked to build a working prototype which could measure the water...bachelor thesis 2016

de Jong, R.J. (author), Zwart, D.J. (author)This thesis shows the successful development of an acoustic channel model to be used for optimisation of localisation. It uses an eigenray approximation, implemented as the image source method to determine a channel impulse response. The image source method however limits the model to environments which can be reduced to cuboid shaped rooms as...bachelor thesis 2016

De Vaere, P.N.T. (author), Abrahams, M.P. (author), Adrichem, D.L. (author), Booms, D.J. (author), Oudsen, A.F. (author)This thesis describes the development of a cheap and robust leg module for a modular robot. It begins with the selection of three suitable motors sourced from three different suppliers. Next, these motors are thoroughly tested, and based on the test results their efficiency is maximised. Then, the mechanical structure of the leg module and its...bachelor thesis 2016

Kokke, C.A. (author), Blom, J.F.J. (author)Underwater robotics face an interesting challenge. Since electromagnetic waves barely propagate underwater, systems like GPS are unusable. However, for a robot to function autonomously, it needs to be able to know its position. Because of this, using acoustic waves for transmitting signals underwater has been established to be the way forward....bachelor thesis 2016

Bons, W.J.W. (author), Hol, T. (author)The quality of a loudspeaker system is largely determined by the distortion of the output signal, resulting from the non-ideal transfer of the loudspeaker and amplifier. This report proposes a method of reducing the distortion in the output signal by using a topology with active feedback. The feedback control unit, which is implemented by a...bachelor thesis 2016

Fuchs, P.S. (author)In magnetic resonance imaging (MRI) the interest in electric properties tomography (EPT) is growing. In current EPT applications the reconstruction is performed based on the Helmholtz equation which relies on the assumption of a homogeneous contrast. The goal of this thesis is to present new approaches to reconstruct the electrical properties...master thesis 2016

Trommel, R.P. (author)Over the past five years, deep learning techniques have led to astounding breakthroughs in many areas, like speech recognition and computer vision applications. The application of deep learning in the radar domain has however been rather limited. The merit of using deep learning techniques for the purpose of human gait classification in radar is...master thesis 2016
