Raghavan, V.S. (author)In the elderly population, falls are one of the major causes of injuries. Fall detection algorithms for wearable devices in the literature were found to focus on differentiating Activities of Daily Living (ADL) from falls, rather than on early fall detection and prevention before impact. This thesis work was aimed at providing accurate estimates...student report 2016

Admiraal, M. (author), Couasnon, A. (author), Huijzenveld, T. (author), Hutten, R. (author), Schölvinck, O. (author), Van Veen, N. (author)In Nicaragua, active research for arsenic started in 1996, after the first case of arsenic poisoning was reported in a rural community. Arsenic concentrations present in drinking water cause chronic poisoning, which depending on the exposure, lead to several life-threatening long term effects. It is however unknown to what extent this...student report 2015

Izeboud, Petra (author)Polder areas as typical in the Netherlands require real time control on the water levels. Efficient pumping is a subject with increasing interest due to a required use of 20% green energy by 2020 set by the government. In 2010, the energy requirements already exceeded 175 GWh per year. For optimal control, water level predictions are important....master thesis 2017

Shamsa, Y. (author)In this thesis, a UWB pulse generator is designed to be implemented in IBM 0.13 um technology. The pulse generator has a high spectral efficiency. Using amplitude control, any mismatch, process variation or temperature variation can be compensated for to comply with the UWB FCC mask. The pulse has an approximate duration of 2ns. The current...master thesis 2009

De Jonghe, Thomas (author)High performance continuous fiber-reinforced composites are becoming increasingly important in the aerospace industry. In these structures, internal damage is often created and propagated throughout the lifetime, having a negative impact on the structural properties. In order to allow for condition-based maintenance, there is a need for reliable...master thesis 2020

Zha, X. (author)In the past two decades, dental implants have been an essential component of the public health. However, lack of a reliable and safe dental surgery imaging modality remains a major problem. Optical coherence tomography (OCT) is an interferometic optical imaging modality that is somewhat similar to B-mode ultrasound but utilizes infrared light...master thesis 2011

Vissers, B.H.A. (author)When a humanoid robot is performing a certain task and is simultaneously maintaining balance, it is important that it can accurately measure its own state. The state is described by a number of variables, such as the center of mass (CoM) and the location of the feet. This information is used by the motion controllers to properly execute the task...master thesis 2012

Suresh Kumar, Nivas Kumar (author)In research, the overall power production in a wind farm is typically increased by employing model-based wind farm control. A controller, in an open-loop setting, operates based on the velocity of the wind flow, predicted by a wind farm model. For a controller to achieve the desired level of power production, a wind farm model has to be accurate...master thesis 2018

Keemink, H. (author)With the advent of smart thermostats like Toon®, detailed information about operation and usage of central heating boilers has become easily available. However, this information is not used in a systematic way by most companies including Eneco, and the wealth of information within is not available to the users. This has a few drawbacks. For...master thesis 2016

Ockeloen, W.J. (author)Thesis study into an alternative design for breakwaters made of granular materials like sand and quarry stone. In this design, the breakwater is constructed of a sand core and a layer of large stones directly on top of it, without the traditional filter layers in-between. The single layer of stones serves as one open filter layer that has to...master thesis 2007

de Ridder, K.M. (author)Convex guidance is a developing guidance algorithm that seeks to unify the trajectory optimisation for pin-point landings. The unification would mean the elimination of the need of different optimisation techniques for different stages of the landing. Using convex optimisation, convex guidance is guaranteed to find the global-optimum of the design...master thesis 2016

Karunanithi, V. (author)Navigation systems using pulsar signals have been of great interest ever since the discovery of pulsars in 1967 and various studies were carried out ever since to determine the feasibility of such systems. The successful working of a navigation system using pulsar would mean that spacecraft can maneuver through the deep space with very little...master thesis 2012

de Bruijn, Janno (author)In the Netherlands there are many bridges that crosses waterways, which are key nodes in the transportation system. The safety and integrity of these bridges is nowadays assessed by (visual) inspections at regular intervals. This approach cannot provide information about damage development in between inspections, leading to potential failure or...master thesis 2019
