The HPLWR (High Performance Light Water Reactor) is the European version of the SCWR (Supercritical Water Reactor) and is one of the Generation IV concepts that have enhanced safety, improved efficiency and less nuclear waste compared to current nuclear reactors. A possible way to enhance the safety is by using natural convection as the driving...

In this paper the stability properties of the vibrations of a singular degree of freedom oscillator with a periodically and multi-stepwise time-varying mass are studied. The free vibrations and the vibrations due to two types of forcing are investigated.

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.

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...

In the Westerwald area clay quarries are in production. In order to assess the stability of the slopes the geotechnical characterisation of these quarries needs to be improved. This report provides the justification for a working plan for a thorough but quick assessment of existing slopes in clay mines. Literature is consulted for the...

In Nederland wordt het steeds moeilijker om bouwdokken, voor het vervaardigen van afzinkelementen van een afzinktunnel, aan te leggen. Daarom wordt uitgeweken naar reeds bestaande bouwdokken, en worden de tunnelelementen over langere afstanden en ook over zee vervoerd. De krachten en momenten die door de golfbelasting, tijdens transport over zee...

Usually, concrete bridges contain a ‘thick’ bridge deck. For various reasons, bridges are constructed with railings. This thesis discusses the stability problem of concrete bridges, which are designed with integrated railings into the carrying construction. The most important advantage, using load bearing railings, is a thinner bridge deck. This...

Hybrid laminar flow control (HLFC) reduces skin friction drag, by combining boundary layer suction with pressure gradient tailoring to delay boundary layer transition. This research addresses two key developments required to perform the aerodynamic design of suction-type HLFC components. First, an existing numerical transition prediction tool...

De Heij, J. (author)
The first one who studied the problem of armour layer stability was Iribarren (1938). Iribarren derived stability criteria that were based on the acting physical processes on the slope of a structure. In the stability criteria of Iribarren only the influence of a few structural and hydraulic parameters were taken into account. In 1988 Van der...

In this report an analysis of data from a series of tests is presented on the stability of the toe structure of rubble mound breakwaters. The existing knowledge on toe stability and the influence of all governing parameters in the existing knowledge is reviewed. The tests which were performed for the present research are treated extensively. The...

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...

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...

In this thesis the equilibrium cross-sectional areas of a tidal inlet are investigated. The most common used methods to study cross-sectional stability are the Escoffier method (Escoffier, 1940) and the Modified Escoffier method (Van de Kreeke, 2004). The Escoffier methods are mainly empirical and lack physical justification. Therefore, in this...

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...

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...

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...

In this MSc thesis it is investigated how the first version of concrete armour unit Xbloc+, Xbloc+ v1, acquires its stability. The stability mechanisms are investigated by conducting two type of physical model tests. First, 23 dry pull-out tests are done to obtain insights into the aspects and mechanisms that influence the...

Block mattresses are widely used bed protection elements under non-uniform flows. Previous studies show that the turbulence of the flow plays a key role on the instability of the mattress. However, in the available design equations, the turbulence intensity is included as a magnification factor roughly and qualitatively defined. Consequently,...

After consulting the "Department of Environment" in Australia it was suggested that an extensive generic study about Tidal Inlets on Littoral drift shores gives them an insight in the processes at work and also the possibilities to improve the stability in order to make tidal inlets suitable for safe navigation. This report describes the most...
