van Zanten, Jonathan (author)Semi-active lower limb prostheses currently use variable damping to generate the gait cycle. This, however, only dissipates energy. Variable stiffness can store and release energy, making prostheses more efficient for walking. This study aims to design and evaluate a semi-active adjustable stiffness ankle-knee prosthesis that can change its...master thesis 2024

Smits, Jurriën (author)Energy harvesting has gained lots of interest over the past few decades. This study explores the application of energy harvesting in lower limb prosthetic devices. The control system of a lower limb prosthesis includes sensors, wireless<br/>systems and other active components which all require battery power. In order to save some of this battery...master thesis 2024

Zeven, Koen (author)For this thesis, we consider two $k$-colorings of a graph $G$ adjacent if one can recolor one into the other by changing the color of one vertex. The reconfiguration graph of a graph $G$ on $k$ colors $\mathcal{C}_{k}(G)$ is the graph for which the vertices are the $k$-colorings of $G$, and an edge is between two $k$-colorings if they are...bachelor thesis 2023

van der Windt, Bob (author)Fluid-controlled actuators are widely used in lower limb prostheses. Most fluid-controlled actuators have valves integrated into the cylinder systems and require complex manufacturing steps, making these systems expensive. A cost-effective production method for these complex actuator valve systems is 3D-printing. The goal of this research is to...master thesis 2022

Houwink, Quint (author)Optical microscopes are fundamentally limited to a resolution of several hundreds of nanometers by the diffraction of light. Single-molecule localization microscopy (SMLM) circumvents this limit by sparsely exciting fluorescent molecules at different time instances. Single molecules can subsequently be localized with improved precision over the...master thesis 2021

Alhamad Mahmood Abdulaziz M, Mahmood (author)The aim of this study is to reduce the risk of the ongoing Geothermal exploration effort in Geneva Basin by estimating the influence of the natural fracture on the reservoir properties. A Discrete Fracture Network (DFN) was generated to resemble the fracture network in the Lower Cretaceous carbonate reservoir. The DFN modelling approach is using...master thesis 2021

Liu, Carmen (author)One of the challenges associated with offshore wind turbine installations is the mating phase. Aligning a transition piece onto its substructure under offshore conditions is a complicated and time-consuming procedure. Another issue found in a number of commissioned offshore wind turbines is related to the sustainability of the connection between...master thesis 2021

Boogaard, Lars (author)Lower limb exoskeletons enable paraplegic patients to stand-up and walk again. However, the weight and overall functional performance of the exoskeleton prevents them from being widely used. To reduce the weight and increase<br/>the performance, pneumatic actuators can be used as an alternative to the commonly used electromechanical actuators....master thesis 2021

Molenaar, Mitchel (author)Patellar tendinopathy (PT) is a common manifestation in jumping sports characterized by pain and a reduced load bearing capacity. The exact cause of PT has not been determined, which makes it difficult to prevent and treat. A stiffer landing technique might be a risk-factor for PT. Retraining of the landing technique into a less stiffer...master thesis 2020

MacDonald-Nelson, James (author)Despite relatively progressive policies put forth by the Canadian government to tackle the challenge of climate mitigation, cities and regions across the country are only beginning to address the equally important task of adaptation. This conversation typically focuses on the spatial adaptability of shorelines, dense urban environments, and the...master thesis 2020

Zhang, Kaiwen (author)In radio astronomy (RA), one of the key tasks is the estimation of the celestial source powers, i.e. imaging. To maximize the performance, it is crucial to optimize the receiver locations before the construction of a telescope array. However, although system calibration is an integral and crucial process of imaging, it has rarely been addressed...master thesis 2020

Ahsmann, Laura (author)This thesis explains the research into and implementation of overuse lower-limb injury prediction among military recruits, using wearable plantar-pressure sensing and biomechanical gait algorithms. The research has been done with the purpose of designing a usable, affordable and accurate injury-prevention tool, increasing both military wellbeing...master thesis 2020

Bakker, Floor (author)To exploit its socio-economic functions, engineering measures are regularly applied in estuaries. Estuaries are, however, known to be very complex systems. Stemming from this complexity is the generation of a so-called estuarine turbidity maximum (ETM), which poses great siltation problems to the engineering measures. An engineering measure,...master thesis 2020

Broderick, Cathy (author)This project investigates the needs of diabetic and vascular amputees to establish design criteria for a new lower-limb prosthesis liner specifically for diabetes and vascular patients. Initially, a literature review was conducted to investigate liner material properties and outcomes during use, as well as how often diabetic and older amputees...master thesis 2019

Izzi, Fabio (author)Recognising the user’s locomotive intentions is crucial for the correct functionality of exoskeletons and active orthoses. For gait applications, extrapolating control inputs from the arm swing may be worthwhile, since arm oscillations naturally occur during human locomotion. A similar method would be unaffected by severe impairments of the...master thesis 2019

Goense, Twan (author)To develop high enthalpy geothermal systems in the Netherlands, reservoirs with a depth greater than 4000 m need to be targeted. The Lower Carboniferous limestone is proposed as the main target due to its depth and wide occurrence. To investigate the potential of this formation, the physical rock properties are studied in a variety of laboratory...master thesis 2018

van den Bogaerdt, Pim (author)We investigate the use of relaxed decision diagrams for obtaining lower bounds on multi-machine scheduling problems. The type of scheduling problem we consider models a railway service site where maintenance jobs are performed, but is sufficiently general to potentially have wider applicability.<br/>We find that our decision diagram formulation...master thesis 2018

Siebinga, Olger (author)Currently, lower-body exoskeletons for<br/>paraplegics are investigated as an alternative to wheelchairs<br/>and as an exercise method with medical benefits. Literature<br/>provides little examples for users to influence the<br/>length or frequency of steps taken by the exoskeleton,<br/>complicating stability and practical usability. This study...master thesis 2018

Graat, Stefan (author)With a rapidly growing population and subsequent technological developments, an increase in demand of rare-earth metals evolves. Land-based deposits seem to be insufficient and shortage impends within the coming decades. Mineral resources from the deep ocean are considered as a possible complement. These minerals occur in various forms. One of...master thesis 2017
