Theelen, M.J. (author)Thin film CIGS solar cells and individual layers within these solar cells have been tested in order to assess their long term stability. Alongside with the execution of standard tests, in which elevated temperatures and humidity levels are used, the solar cells have also been exposed to a combination of elevated temperature and humidity and...doctoral thesis 2015

Gromotka, Z.J.G. (author)The tubing performance relation curve is a measure of well performance in gas well engineering. It describes the two-phase flow inside a well and as such is modeled as a two-phase one dimensional pipe flow. Convention claims that production points on the TPR curve to the right of its minimum are stable. There also exist claims about the region...master thesis 2015

Yan, F. (author), Goverde, R.M.P. (author)To satisfy the growing passenger transportation demands and improve the service quality n railway system, a more stable and robust timetable needs to be designed while considering highly utilized capacity. Acyclic timetable is extensively applied in large ailway networks. In order to acquire the quality of timetable, analytical timetable...conference paper 2015

Goverde, R.M.P. (author), Besinovic, N. (author), Binder, A. (author), Cacchiani, V. (author), Quaglietta, E. (author), Roberti, R. (author), Toth, P. (author)The performance of railway operations depends highly on the quality of the railway timetable. In particular for dense railway networks it can be a challenge to obtain a stable robust conflict-free and energy-efficient timetable with acceptable infrastructure occupation and short travel times. This paper presents a performance-based railway...conference paper 2015

Van Heumen, D.J. (author)We beschouwen Brouwers roterende lichaam, een voorbeeld van een mechanisch systeem met het volgende paradoxale gedrag; zonder demping is er stabiliteit, met demping is er sprake van instabiliteit. Met modulatie van de hoeksnelheid wordt er een model afgeleid waarbij we pogen de instabiele gevallen te stabiliseren, hierbij is het meenemen van de...bachelor thesis 2015

Smulders, J. (author)The devastation caused by Hurricane Ike in the Galveston Bay area (Texas, United States of America) proved the necessity of an improved water defense. Multiple flood risk reduction studies were undertaken. The Texas A&M University of Galveston proposed the Ike Dike, a fortification of the coastal spine to prevent a storm surge from entering the...master thesis 2014

Novati, G. (author)We developed bio-inspired reduced-order models of swimmers, consisting of a self-propelling pair of rotating cylinders. The aim of the project is twofold. First, simplified and non-deforming geometries can more easily be employed in small-scale robotic applications to solve relevant engineering problems. Second, they can serve as reduced physics...master thesis 2014

Lavies, H.G. (author)The breakwaters of IJmuiden are of a unique design; a riprap core is covered with a thick impermeable asphalt slab. During construction and after completion, slope instability caused extensive damage. Placement of a concrete cube armour layer prevented further damage to the asphalt, but proved to be unstable and required a significant amount of...master thesis 2014

Ramachandra Rao, P. (author), Milosavljevic, S. (author), Kroth, U. (author), Laubis, C. (author), Nihtianov, S. (author)Newly developed “pure-boron” photodiodes, with high sensitivity and stability in the whole ultraviolet range (UV), are described. The main purpose of this work is to create and characterize a large-area UV photodiode, representing a structure of a pixel in a backside illuminated CMOS image sensor, featuring maximum fill factor and hence...lecture notes 2014

Van de Sande, S.A.H. (author), Uijttewaal, W.S.J. (author), Verheij, H.J. (author)Granular filters are used for protection against scour and erosion of base material. For a proper functioning it is necessary that at the interfaces between the filter structure, the subsoil and the water flowing above the filter structure no material will be transported. Different types of granular filters can be distinguished, this paper...conference paper 2014

Wijchers, M.S. (author)In this thesis a special kind of differential equation will be analysed, namely the delay differential equation. For test equations the stability behaviour is analysed and there's checked whether there is a method to prove stability. Also, a full description is given, for the model submitted by INCAS3.bachelor thesis 2014

Roelse, F.P. (author)In the last decades shipping has increased significantly, resulting in larger ships with an increasing power in bow thrusters. Due to this increasing power, the hydraulic loads at bottom protection near quay structures has also increased, making a traditional bed protection more expensive. Therefore an alternative design method is suggested in...master thesis 2014

Van 't Wout, E. (author)The aim of this thesis is to design a computational method that can be used in modern stealth technology. In particular, the computational method should be capable to simulate scattering of ultra-wideband radar signals for military aircraft constructed with ferromagnetic radar absorbent materials. A full-wave boundary element method has been...doctoral thesis 2013

Roos, P.C. (author), Schuttelaars, H.M. (author), Brouwer, R.L. (author)Barrier coasts display a chain of islands, separated by tidal inlets that connect a back-barrier basin to a sea or ocean. Observations show that barrier island length generally decreases for increasing tidal range and increasing basin area. However, this has neither been reproduced in model studies nor explained from the underlying physics. This...journal article 2013

Verdegaal, I. (author)The permeability of a breakwater is of great importance for the stability of the armour layer. The influence of the structural permeability on the stability of rock armour units was already researched by Van der Meer using the 'notional' permeabiltiy. However, for single layer interlocking armour units the influence core permeability is rather...master thesis 2013

Van de Wiel, B.J.H. (author), Moene, A.F. (author), Jonker, H.J.J. (author)The mechanism behind the collapse of turbulence in the evening as a precursor to the onset of the very stable boundary layer is investigated. To this end a cooled, pressure-driven flow is investigated by means of a local similarity model. Simulations reveal a temporary collapse of turbulence whenever the surface heat extraction, expressed in its...journal article 2012

A set of 90 high-resolution Large Eddy Simulations is used to systematically explore the sensitivity of continental deep convection to the relative humidity and stability of the free troposphere. It appears that variations in the mass-flux profiles are...journal article 2012

The theoretical findings behind stable coastal inlet cross-sectional behaviour will be reviewed, analysed and confronted with empirical findings, leading to some unresolved questions. Second, seasonal variations will be shown to induce...conference paper 2012
