De Jong, P.H. (author)The design of the ordinary bicycle has barely changed since the end of the 19th century. Until then it evolved to a well ridable machine with no need for further drastic modifications. However, around 2011 it was shown that, just like an ordinary bicycle, strange appearing designs could also be stable. One of these designs was a bicycle that...master thesis 2017

Damsteeg-van Berkel, S. (author)DNA can function as a significant part of evidence in forensic investigation, because it can link a potential perpetrator to a crime. Even by skin contact, micro-traces of DNA-containing material can be transferred. This type of DNA is called ‘trace DNA’. When DNA is collected from an evidentiary item for forensic purposes, the goal is to...master thesis 2017

Wang, Y. (author)Introduction: In this study, a novel anthropomorphic head phantom for quantitative image quality assessment in cone beam computed tomography (CBCT) is proposed. The phantom is composed of tissue equivalent materials (TEMs) which are suitable for ‘ home made’ fabrication methods such as silicone casting and 3D printing and equipped with inserts...master thesis 2017

Posthoorn, P. (author)Current endoscopic devices cause great discomfort to the patient because they need to be pushed from outside the patient to manoeuvre through the intestine. Self-propelling endo- scopic concepts have been proposed, but these cause unnecessary trauma to the patient or are unable to travel to the end of the large intestine and back. This study...master thesis 2017

Vijverberg, J.W. (author)Background: Aseptic loosening [AL] of cementless implants is causing approximately 60% of total knee and total hip arthroplasty revisions. AL is caused among other factors by micromotion. The result is that the bone around the prosthesis is replaced by a fibrous membrane. This fibrous membrane allows for more micromotion and we thus enter a...master thesis 2016

Calkoen, H.G.M. (author)The structural response of active skeletal muscle is derived from a combination of sarcomere contraction properties, collagen fibres in the connective tissue, and incompressibility. The role of collagen tissues could be substantial but is still not completely understood. Only few studies have looked into the functionality of collagen...master thesis 2016

Vermaire, A.A. (author)Vestibular information from both sides of the head converges within the vestibular nuclei to contribute to postural stabilization of the head and body, and to provide accurate perceptions of self-motion. It remains uncertain whether these responses are evoked through equivalent integration processes, because our perception of head position is...master thesis 2016

Bauer, Q. (author)Previous research showed fracture failure in the outsole of sports footwear. There was no method available for the quantification of the material behavior in with this failure mechanism. Therefor the goal of this research was to develop a mechanical test method for quantification of fatigue fracture behavior of a material when a crack is present...master thesis 2016

Verga, F.G.E. (author)Carbon dioxide pneumatically actuated autonomous systems suffer a major energy loss whenever the pressure is reduced from saturation pressure to the designed pressure. This loss account of approximately 60% of the total energy enclosed in the pressurized carbon dioxide canister, considering an isothermal expansion. To address this problem, this...master thesis 2016

Antico, M. (author)In external beam radiation therapy (EBRT) for prostate cancer, prostate motion and, more generally, intra-fractional anatomical changes in the pelvic region can lead to significant plan efficacy degradation, possibly underdosing the target and overdosing the organs at risk (OARs). Since through image-guided radiation therapy (IGRT) it is...master thesis 2016

van Wijdeven, M.A.P. (author)A passive exoskeleton was designed with the goal of reducing metabolic cost of human walking by augmenting moments around the hip joint. A novel approach, using leaf springs parallel to the human leg, was proposed. A kinematic model including man-machine interface compliance was optimized and results showed a maximal reduction of metabolic cost...master thesis 2016

Sande, M.G. (author)Bacterial infection is one of the most severe complications of titanium based implants which leads to complete implant failure. The treatment of such infections requires multiple surgeries followed by long term antibiotic therapies with significant traumatic consequences to patients and high financial burden for healthcare systems. One option to...master thesis 2016

Jónasdóttir, H. (author)Musculoskeletal modeling and dynamics simulations are common tools used to analyse gait in patients with Cerebral Palsy (CP). These musculoskeletal models are usually generic models based on anatomical measurements obtained from cadavers, hence no subject characteristics are included. It is important to understand the accuracy of using a generic...master thesis 2016

Amara, V.D. (author)Elastic joints endow robots with advantages including energy-efficiency, safety and performance. To optimally actuate such joints, robotic tasks are formulated as optimal control problems with task objectives and their solutions provide the optimal control policies. However, two general challenges while solving these problems exist. They include...master thesis 2016

Moreo, M.

Only 5% of the amputees own a prosthesis because there are distribution and maintenance problems, as well as cultural issues surrounding...master thesis 2016
