Kleinhans, M.G. (author), Jagers, H.R.A. (author), Mosselman, E. (author), Sloff, C.J. (author)At river bifurcations, water and sediment are divided over two branches. The dynamics of the bifurcation determine the long-term evolution (centuries) of the downstream branches, potentially leading to avulsion, but the dynamics are poorly understood. The long-term evolution can only be studied by one-dimensional models because of computational...journal article 2008

Bos, J.A. (author)Installed wind power world wide is increasing rapidly. The increase in wind power in the European electricity grid is expected to have its impact on the system behaviour. A European study, European Wind Integration Study (EWIS), was thus set up to study the impact of wind power. This thesis was carried out in parallel with EWIS and overlaps at...master thesis 2008

Hughes, S.A. (author)A 1-to-25 scale physical model of a typical cross section of the levee along the Mississippi River Gulf Outlet (MRGO) was con-structed at the U.S. Army Engineer Research and Development Centers Coastal and Hydraulics Laboratory in Vicksburg, MS. The purpose of the physical model was to obtain hydrodynamic measurements of unsteady flow...report 2008

Baart, S.A. (author)This thesis investigates the stability of rocks in toe bunds for rubble mound breakwaters. Presently recommended design tools lack a reasonable degree of accuracy to assess required toe element dimensions. The goal of this research is to improve the insight in the physical process related to stability of toe bund elements under wave load....master thesis 2008

Aanhaanen, J.A.M. (author)The Master’s thesis has focussed on the stability of a facetted shell structure. The research contributes to a Ph.D. research currently carried out at the Technical University of Denmark (DTU), which investigates the possibilities to design and build a shell structure from flat glass panels. The structure is a so-called plate (facetted)...master thesis 2008

Oosthoek, J. (author)Gabion mattresses consist out of a steel wire grid in which fill material is retained. The advantage of these constructions is that the individual particle stability is no longer of importance. The containing function of the grid results in the effect that the fill material starts to behave as a group. Next to that the mattresses are all...master thesis 2008

Kumar, K. (author)Weak capture in the restricted problem of three bodies refers to transitory motion between the primaries. Such behavior has interesting applications in space mission design, notably, in finding optimal transfer trajectories that surpass the performance of traditional Hohmann transfers. The Weak Stability Boundary (WSB) is a mathematical set that...master thesis 2008

Derks, G. (author), Ebert, U. (author), Meulenbroek, B. (author)Streamer ionization fronts are pulled fronts that propagate into a linearly unstable state; the spatial decay of the initial condition of a planar front selects dynamically one specific long-time attractor out of a continuous family. A stability analysis for perturbations in the transverse direction has to take these features into account. In...journal article 2008

Sveinbjornsson, P.I. (author)A major part of the breakwaters constructed in the world are the so-called conventional rouble mound breakwaters, which consist of a core, a filter layer and a heavy armour layer. An alternative to the conventional rouble mound breakwater is a berm breakwater. Berm breakwaters have mainly developed in two directions over the last couple of...master thesis 2008

(author)It was hypothesized that rheumatoid arthritis (RA) patients with a total knee prosthesis that allows axial rotation of the bearing (MB) will show more co-contraction to stabilize the knee joint during a step-up task than RA patients with a fixed bearing total knee prosthesis (FB) where this rotational freedom is absent while having the same...journal article 2008

Tenzer, R. (author), Novák, P. (author)The eigenvalue decomposition technique is used for analysis of conditionality of two alternative solutions for a determination of the geoid from local gravity data. The first solution is based on the standard two-step approach utilising the inverse of the Abel-Poisson integral equation (downward continuation) and consequently the Stokes/Hotine...journal article 2008

Dijkstra, O.P.J. (author)In coastal regions where the land is sensitive to erosion, but also for harbours and ports, numerous types of defensive structures have been developed to protect it from the effects of incident waves. More recently breakwaters have been constructed which combine the stability characteristics of a conventional two-layered uniform sloped...master thesis 2008

(author)The current research is aimed at evaluating the applicability of a numerical flow model to predict bed damage. First, an experimental study was carried out to get more inside into the relation between flow forces acting on a bed and the bed response (damage). The experiments were then used as the basis for the evaluation. Second, the flow was...conference paper 2008

Marcel, C.P. (author)The stability of natural circulation boiling water reactors is investigated with a strong emphasis on experiments. Two different facilities are used for such a task: the GENESIS facility (to which a void reactivity feedback system is artificially added) and the CIRCUS facility. In addition, numerical codes are also used in the investigation.doctoral thesis 2007

De Rover, R.A. (author)At breakwater and seawall projects at Port St Francis and Scarborough breakage of single layer interlocking armour units was observed. It is generally assumed that breakage of single layer armour units has a significant negative effect on the hydraulic stability of a rubble mound breakwater. The significant decrease of interlocking capacity and...master thesis 2007

(author)Morphodynamics of a tidal inlet system on a micro-tidal coast in a tropical monsoon influenced region is modelled and discussed. Effects of tides, waves, river flows and system configuration on the inlet morphologies are investigated with the aid of process-based state-of-the-art numerical models. Seasonal and episodic behaviour of the inlet...conference paper 2007

Wittwer, T. (author), Klees, R. (author), Seitz, K. (author), Heck, B. (author)We present software for spherical harmonic analysis (SHA) and spherical harmonic synthesis (SHS), which can be used for essentially arbitrary degrees and all co-latitudes in the interval (0°, 180°). The routines use extended-range floating-point arithmetic, in particular for the computation of the associated Legendre functions. The price to be...journal article 2007
