Kalpoe, I.R. (author)Case II (super)-diffusion is characterized by a diffusion like process that goes faster than the square root of time. Superdiffusion can occur in polymeric structures if a stress gradient enhances the diffusion process. In such a case the part of the polymer invaded by the penetrant, e.g. CO2, undergoes a transition in structure from the glass...bachelor thesis 2009

ter Meulen, Ruben (author)A random periodic two-dimensional spring network us built using a Poisson disk distribution and computing the Delaunay triangulation of the centers of the disks. The edges of the network represent springs that obey Hooke’s law with an adjustment on the spring constant. The adjustment allows spring to soften and to break. The two-dimensional...bachelor thesis 2019

van der Zalm, Joost (author)The goal of the research described in this thesis was to investigate the basis of dissipation dilution as well as make it comprehensible. In the written literature we could find that the kinetic energy of an oscillating beam is stored into two types of potential energy~\cite{Kippenberg, Kotthaus}. A dissipative bending component and a...bachelor thesis 2019

Meijer, I.D. (author), Morssink, B.J.C. (author)There are many different studies that try to use physiological features to determine stress. But there exists a lot of uncertainty about which physiological signals and features are the best classifiers and a lot of discrepancies in classification accuracies exist. This study proposes a novel method for the detection of stress. This method contains...bachelor thesis 2020

Mercimek, Y. (author), Meppelink, G.J. (author)This study proposes a system for constant monitoring of ECG and respiration signals using a wearable. The proposed system uses capacitively-coupled electrodes for the measuring of the ECG-signal and a resistive strain sensor for the measuring of the respiration signal. The system applies the strain sensor to the abdomen of a patient, and...bachelor thesis 2020

Opdam, R.C.G. (author)In this bachelor thesis, blood flow in simplified stenosed and unstenosed arteries under influence of a steady localized non-uniform magnetic field is investigated by performing 3D numerical simulations. The mathematical model is a combination of the principles of ferrohydrodynamics (FHD), magnetohydrodynamics (MHD) and a simplified set of...bachelor thesis 2008

Bootsma, M.T. (author)This project focuses on the shear strength of Devonian sandstone cobbles that will protect the area between the sea-water breaker and the beach and will be used to construct a runway for a large crane for the new Maasvlakte 2. In rock slope design the shear strength of sliding interfaces is often based on Coulomb’s model in which shear strength ...bachelor thesis 2010

Negem, Taha (author)Residual stress analysis within hybrid structures is the focus of this study. The non linear stresses through the thickness are determined using a semi-destructive method known as Incremental Hole Drilling (IHD). Finite element modeling is used to build a mathematical code simulating GLARE laminates with initial residual stresses applied. The...master thesis 2018

Schouten, Matthijs (author)As collisions between aircraft and birds happen many thousands of times every year, all aspects of such impact events need to be taken into account in the process of designing an aircraft. One aspect that poses a risk is caused by the vibrations induced during bird impact. These vibrations are propagated through the aircraft structure by stress...master thesis 2020

Agarwal, A. (author)This research, performed at Airbus Defence and Space Ground System Test Engineering department in Seville, Spain, is a part of ELDAS (Engineering for Leak Detection in Aircraft Systems) project. It deals with carrying out an investigation on the leak behaviour of the sealing systems used in an aircraft particularly A400M. The sealing integrity...master thesis 2014

Geertzen, Sander Geertzen (author)Drought and subsidence are two out of several water-related urban climate adaptation challenges many cities in the Netherlands currently face. Drought is expected to increase in frequency and extent due to climate change. Therefore, drought is likely to further pressurize (subsiding) urban areas in the coming decades. Although the impact of...master thesis 2021

de Korte, Coen (author)Monitoring fatigue damage is complex because ships are designed to crack after 20 years, and typically cracks will only occur after a long time. A novel fatigue damage sensor has been invented to indicate damage in corresponding aluminium welded joints. Fatigue damage is accelerated by introducing a stress concentration in the sensor w.r.t. the...master thesis 2018

Gavriilidis, Prodromos (author)Introduction: Atherosclerosis, the major source of cardiovascular diseases, is one of the leading causes of death. During atherosclerosis the arterial wall is affected by a complex process of lipid driven inflammation that leads to thickening of the arterial wall resulting in a so called plaque. Because of plaque growth, the lumen of the artery...master thesis 2020

Romijn, Kasja (author)Over the past few decades, the Netherlands has built numerous steel railway bridges to improve its infrastructure. The repeated loading from railway traffic makes steel bridges susceptible to fatigue damage. The stress ranges at fatigue-prone locations are generally higher in railway bridges than in road traffic bridges. Due to the limited space...master thesis 2023

Malik, Naseem (author)Magnets for High Energy Physics applications built to date are generally superconducting magnets, which operate at cryogenic temperatures. The reliability and safety of the applications are entirely dependent on good design which in turn rely heavily on predictable materials performance. Where at these low temperatures the fracture toughness is...master thesis 2021

Nooren, T.A. (author)A lot of research is being done in the field of Photonic Integrated Circuits (PICs) for use in telecom, datacom, optical sensing and visible light applications. Optical packaging of these PICs is still a challenge; increasing complexity leads to a higher number of interconnects and, combined with the need for sub-micrometer accuracy, this places...master thesis 2015

Tanwar, Gautam (author)Quadrangular Grid shells have generated interest in recent years for their application in rationalizing free form geometry in the built environment. Shell structure are efficient because their form is governed by flow of internal forces. But while discretizing shells into grid shells, instead of using flow of forces, current method follows...master thesis 2019
