Khoe, Y.S. (author)Fixation of uncemented implants is known to be more problematic than cemented implants as the proces relies on the growth of bone into the porous implant surface. This bone growth determines the fixation of the implant and has been the subject of many investigations [1-6]. A literature survey [7] revealed that these models are either a highly...master thesis 2009

Van den Hoogen, F.G.P. (author)In cell experiments there is an interest to acquire information how a cell responds to external loads. In gel studies these cells are imbedded in gel and the gel is deformed externally. Because the gel is deformed, the cells inside the gel will deform as well. In order to capture the deformation of the cell a confocal microscope is used. A...master thesis 2009

Verbart Guerrero, A. (author)This thesis presents a comparative study of two Evolutionary Structural Optimization (ESO) methods: the Isocontour ESO Method (ISOESO) and the Level Set Based ESO Method (LS-ESO). These methods are both variants of the classical Evolutionary Structural Optimization (ESO) method which is based on removing gradually low-stressed material. Both...master thesis 2009

Nerkens, W. (author)The purpose of this study was to evaluate the influence of glenohumeral conformity on interface micromotions in a metal backed glenoid implant. A force controlled experiment was performed in which a metal backed glenoid component with various PE inlay radii was subjected to a simulated joint reaction force. Local interface micromotions, rim...master thesis 2009

Eenkhoorn, N.C. (author)Full-scale structural testing of of aircraft structures has been and still is the task of the aircraft industry when new aircrafts are developed. The NLR performs structural testing of aircraft structures for certification, this is done using structural test setups. Structural testing consists out of static testing (ultimate load) and fatigue...master thesis 2010

Langeslag, S.A.E. (author)One of the major challenges in drug development is the development of a drug-screening model that closely resembles the adult human heart. Currently many drugs are rejected in late stages of development and even withdrawn from the market due to possible cardiac tissue damaging side effects. The corresponding delay in drug development is mainly...master thesis 2011

Vet, A.F. (author)-Introduction Mammography is the main screening method in early breast cancer detection in most civilized countries. Although the breast cancer mortality rate decreased with 25% since the introduction of mammographic population screening, the method still displays relatively high false negative and false positive rates, resulting in missed...master thesis 2011

Moerkerken, J.W. (author)The human eye is suspended in the orbit, a cavity in the skull that is largely filled with fat (adipose tissue). Fat is a gelatin like substance contained within fat cells surrounded by connective tissue membranes. Fat consists for 80 % of water, therefore it is almost incompressible. Fat supports the eye and eye muscles in the orbit, four...master thesis 2012

Wong, S.I. (author)Pressure hulls are, especially for manned vehicles, one of the key structures of a submarine. Contributing roughly one third to the total submarine weight, these hulls provide a watertight envelope that must bear the hydrostatic external load. The design of such a structure can be complex as the whole submarine has to reach neutral buoyancy....master thesis 2012

Van Kempen, F.C.M. (author)Photolithography is the engineering field where micro-chips are made by creating minuscule patterns on a plate of silicon using light. The patterns are made in a photoactive polymer layer, called a photoresist which was applied to the substrate. These dissolve easily when they are irradiated with light, but resist dissolution during the...master thesis 2012

Heemskerk, R.S. (author)Renewable energy is a trending topic nowadays. Government restrictions force us to produce less CO2 and use more renewable energy sources. One of the ways of becoming a more sustainable society is by using solar energy. Solar panels are promising in supplying a large part of our energy demand. The price per kWh is important to be competitive...master thesis 2013

Van den Broek, S.F. (author)The design of wind turbines is a multidisciplinary process. Most of the codes currently used in industry and academia use low fidelity models, which are not suitable for detailed design. This thesis describes the development of an aerostructural model for wind turbines with a higg fidelity structural solver. This is done by coupling an existing...master thesis 2013

Wolfs, J.H.P. (author)Shells are thin-walled curved structures that have great potential for multistability. However, there does not yet exist a general model that can be used to predict the stable equilibria of an arbitrary shell; this model would have to capture the complex interplay of (initial) geometry, material parameters and (local) prestress. In this thesis...master thesis 2013

Barten, E. (author)The dynamic response of coupled structures is influenced by the mechanical joints connecting the individual substructures. The friction induced by the interfaces causes non-linear and dampinglike effects, which need to be taken into account when applying Experimental Dynamic Substructuring techniques. The traditional techniques impose...master thesis 2013

Yang, X. (author)In this paper, a theoretical and numerical analysis is presented on the squeezed film between a circular rigid oscillating plate and a fixed proximity surface with an incompressible medium. A series of theoretical methods are derived or reviewed, such as lubrication theory from Reynolds (1886), Kuzma(1967), Ishizawa(1966), Beltman(1997) and...master thesis 2014

Pereboom, H.P. (author)The achievable dynamic performance in high-precision systems by applying light and stiff design principles is reaching its limits. To further increase performance, better insight is needed in the cause and effect of the systems modeshapes and forced vibrations. In this way, transfer functions between actuator/excitation sources and sensor...master thesis 2014

De Prieelle, L.S.B. (author)In order to provide further improvements in thermal efficiency, engine designers are trying to optimise one of the components of the engine that has to endure the most severe conditions: the High Pressure Turbine. Furthermore, from a cost perspective, turbine designers are constantly trying to reduce the number of blades in the turbine which...master thesis 2014

Serphos, M.R. (author)Designs to be manufactured by Additive Manufacturing (AM) are subject to geometrical restrictions which are necessary to guarantee successful production. This makes it necessary to modify the obtained topology optimized design such that it is manufacturable. By doing this the optimality of the structure can be reduced. To achieve a...master thesis 2014
