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

Timmermans, Raymond (author)This paper combines the concepts of noise and stability in the iterated prisoner's dilemma. The purpose is to find strategies that score well (have a high cooperation percentage) in a homogeneous noisy environment, but are also robust to invasions. Generally, strategies that perform best under noise are maximally forgiving, however,...bachelor thesis 2021

Koren, G.B. (author)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...bachelor thesis 2010

Bloem, Hugo (author)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...bachelor thesis 2017

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

Woldeyohannes, S.Y. (author)Roads support our daily life, and play crucial role in supporting the infrastructure for economic activities. However, road disaster can be caused by different natural conditions of slope failures such as rainfall, steep topography, brittle geology, etc. Road disaster occurrences do not only cause the primary disaster from the infrastructure...master thesis 2010

Frens, A.B. (author)The main objective of this research was to assess the impact of different placement methods, with different packing densities, on the stability of double layered Antifer-block armour layers. This was done by experimental research in the wave-flume of the Fluid mechanics laboratory of the Faculty of Civil Engineering and Geosciences at Delft...master thesis 2007

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

Klop, Wouter (author)A humanoid robot is being developed, intended to operate robustly in a typical day-to-day human environment. Its ability to react quickly to stochastic disturbances, especially its ability to avoid falling, termed stability in this context, is of prime importance. The choosing of a suitable actuator that affords such stability is seen as a...master thesis 2017

Beekx, R.H.P.A. (author)South Korea is reclaiming land by constructing dams and polders. The large tidal differences along the Korean coast make building these dams a challenging job. One of the solutions in South Korea to cope with the high flow velocities in closure projects is to apply sack gabions. These are steel nets with rocks inside them that weigh up to 3 tons...master thesis 2006

Purgat, P. (author)The flexible power transfer network is a conceptual transfer network for residential areas. The main advantage of the proposed concept is the increased safety and flexibility compared to currently used AC network. The core idea is to incorporate wireless power transfer into the network which leads to inherently safer and more flexible network...master thesis 2016

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

Symes, Patrick (author)This thesis aims to provide insight into the conceptual design phase of Tetrahedron B.V. with regards to buckling stability. Currently, Tetrahedron B.V. assumes an effective length factor of one for determining the cross-section profiles of the Tetrahedron Crane. In this thesis, Euler-Bernoulli beams are used to model every member of this crane,...master thesis 2020

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

Mola Jimenez, Jorge (author)This master thesis analyses different ways to perform assessment in frequency and transient (rotor-angle) stability when high penetration of renewables exists in the grid, based on researches done in the academic world and in industries. The goal of this research focuses on assess the distance to frequency and transient instability in power...master thesis 2017

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

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
