Steenbeek, Jorden (author)High-fidelity hybrid RANS/LES methods are unable to accurately predict the transition from laminar to turbulent boundary layer flows. Usually resulting in an incorrect prediction of boundary layer characteristics. In this study, a hybrid RANS/LES model was developed for transitional boundary layer flows. The transitional kkL-omega turbulence...master thesis 2017

Kar, Attman (author)Across the world, the presence of humans in coastal regions is always increasing. Hydraulic forcing from extreme events is a large risk around the global coastlines, the risk being complicated by the increased human presence along the coasts.<br/>The knowledge that vegetation can be used as a coastal protection measure is not something new. The...master thesis 2017

Ji, Yuanbo (author)Segmentation of medical images is always a challenge due to complicated anatomical structures and poor image quality. In this paper, aiming to solve dual surfaces segmentation problems, we propose a two-layer levelset method with an efficient distance constraint. With the distance constraint, physical information of wall thickness can be imposed...master thesis 2017

Dhingra, Sanjana (author)Nucleation is the initial step for the creation of new crystalline phase. A precise control over nucleation and its kinetics is important for both research and industries. Thus, alternative methods are sought after to extend the toolbox for controlling nucleation. In the 1990's, Non-Photochemical Laser Induced Nucleation (NPLIN) was suggested as...master thesis 2017

Teengs, Pieter (author)Fibre-reinforced polymers (FRPs) are becoming a more commonly used building material in many civil engineering applications including locks. One quality of FRPs is the fact that it has a high strength to weight ratio. By applying FRPs in rolling lock gate design, the self-weight of the gate could be significantly reduced. This in turn could lead...master thesis 2017

Bakker, Tije (author)The Ayeyarwady River (also called Irrawaddy River) is the most important river of Myanmar and due to the country’s rapid development it is expected to become even more important. The river flows roughly from north to south through Myanmar and is very dynamic and mostly unregulated. With a length of 2170 km and an over the year average (highly...student report 2017

Konduri, Praneeta (author)Surgical ventricular reconstruction aims to restore the ideal left ventricular geometry and function and is used as a treatment modality for patients with severe ischemic cardiomyopathy. This study addresses the clinical need for in-silico modelling to estimate the effect of left ventricular reconstruction through Revivent Myocardial Anchoring...master thesis 2017

de Jonge, Kyle (author)Estimators at the production department of Great Lakes Dredge & Dock Company use a number of models to make production estimates for a job. These models require the slurry concentration in the suction arm of a trailing suction hopper dredge (TSHD) as an input. Currently this concentration is estimated based on results of previous projects....master thesis 2017

Versteeg, Edwin (author)Stroke is one of the leading causes of both death and disability in the world. Consequently, the processes underlying motor recovery are a hot research topic. Electroencephalography (EEG) and diffusion weighted magnetic resonance imaging (dMRI) are two modalities that can be used to find functional and structural predictors for this motor...master thesis 2017

van Velden, Karel (author)Airfoil optimizations require costly high-fidelity solvers. By replacing the expensive solver with a cheap to evaluate surrogate model genetic optimization becomes feasible and a global optimum can be obtained. This thesis investigates applicability of surrogate model based optimization for airfoil optimization and provides recommendations...master thesis 2017

Diab, Ibrahim (author)The past few decades have seen a revival of the interest in wireless power transfer (WPT) long after the first experiments dating as far back as Nikolai Tesla in the 19th century. The rise of the autonomous electronic devices like medical implants, or portable devices like mobile phones, have motivated the search for wireless power charging...master thesis 2017

Rioja Cabanillas, Adriana (author)Energy demand is constantly increasing and the use of fossil fuels causes an accumulation of carbon dioxide (CO2) which is an important environmental problem that needs to be solved. A promising solution to this problem would be the electrochemical reduction of CO2 to useful products, using the surplus of electricity from renewable sources. This...master thesis 2017

Guenther, Agnes (author)The study presented in this work investigates the impact of forms of logical reasoning on company performance. Under changing market conditions and uncertainty, executives too often fail to foresee strategic options that lead to superior company performance. One reason for this is that executives tend to rely on deductive/inductive logic in...master thesis 2017

Edmondson, Ben (author)Over the past years Fibre Reinforced Polymers, or FRP, have started making more of an appearance in civil engineering structures. They have the advantages that they are light-weight, do not corrode and theoretically require little maintenance during their lifespan. Originally they were used to construct reinforcement, cables and small bridges...master thesis 2017

Sneha, Sneha (author)The cellular environment is characterized by confinement and macro-molecular crowding: both concepts that have been studied separately. To understand kinetics of enzymatic reactions, there is a need to understand how the diffusional encounters of enzyme and substrate proceed in an environment<br/>that is confined and crowded simultaneously. The...master thesis 2017

den Braber, Tom (author)The goal of this thesis is to learn how exception handling constructs are used by PHP developers. We present an approach for detecting the exception flow of a software system, based on the work of Robillard and Murphy (2003). We show the accuracy of this approach by evaluating the tool on a corpus of three different PHP systems. The approach is...master thesis 2017

Chaudhary, Aditya (author)A tremendous amount of research in improving the efficiency of the single junction crystalline silicon (c-Si) based solar cells has brought its efficiency (26.6%) close to the theoretical maximum achievable conversion<br/>efficiency (29.43%) [1–3]. Thus to further improve the efficiency, new avenues of reducing losses need to be opened up. One...master thesis 2017
