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,...

The goal of this thesis is to create a theoreticalmodel that captures the influence of wind on the horizontal and vertical salinity distribution in an estuary, as well as the dynamics that arise within the estuary. A secondary, numerical model, that uses fewer assumptions, will be developed and analysed. This serves to determine whether the...

This thesis research has been conducted to analyse the sediment dynamics in the Yangon Estuary, in order to define the cause for the sedimentation in Monkey Point Channel. For years, Yangon Port has been suffering from limited accessibility due to the sedimentation in the channel and currently daily dredging is required in order to let ships...

We consider adaptive network models with discrete and continuous state sets obeying dynamical rules that enable application to swarming systems. The 2-state adaptive network contains a supercritical pitchfork bifurcation in the transition between ordered and disordered stationary solutions. We derive an adaptive network model that works on a...

This thesis investigates several kinds of models of describing multi-commodity dynamical flow. Three models have been developed for a spatial logistic network, on which packages are delivered by vehicles and another<br/>model was developed to describe interactions between the customers, the stores and the deliverers, which does not explicitly...

The Wireless Power Transfer (WPT) has been introduced decades ago for low power applications, and more recently, it has been used for industrial high power applications. WPT is gaining popularity because it presents several advantages over the power transfer through cable, such as the galvanic insulation between the power source and the load,...

This master thesis focuses in the study of the application of active flow control in the transitional regime (Re ≈ 3E3) at the rear part of the roof of a 2D Ahmed body geometry. To do so, the natural bifurcations of the problem (which separate the ordered laminar behavior from the first pre-turbulent chaotic behavior) are studied, and different...

In this thesis, it is investigated how the blood flow changes in different physiological situations, using a one-dimensional model, that describes the blood flow in compliant vessels. The one-dimensional model, that describes the blood flow, is derived based on the physical laws of conservation of momentum and conservation of mass. A high...

The Three Body Problem (3BP) has been one of the main celestial mechanics problems in the past few centuries, for a long time studied by both engineers and mathematicians. Its practical purpose is to describe the motion of three particles only under their mutual gravitational interaction, thus it actually represents a ‘model’ of the real...

Self-excited vibrations in Laval rotors supported by hydrodynamic bearings, know as oil whirl, induce friction losses and noise, or may even damage the system. This transient dynamic behaviour is caused by the stable and unstable equilibria in the system. To study this phenomenon, this research uses numerical continuation. This method determines...

A hydrodynamic study shows high flow velocities at the IJsselkop bifurcation during the design discharge of 16,000 m3/s. The study, performed in 2005, concludes that these velocities might affect 1) the stability of IJssel river bed and 2) the stability of the grass cover layer of the flood plain at the bifurcation. This report provides a better...

This study is about the effect of outer-delta bottom topographies adaptations on salt water intrusion in estuaries. An increase in salt water intrusion is considered as problematic in a lot of estuaries in the world. Various solutions are developed in the past to reduce salt water intrusion. These solutions have also negative side effects. An...

Controlling the distribution of water and sediment at river bifurcations is one of the main challenges in river engineering and management. This distribution affects the stability of river bifurcations as well as the distribution of flooding risk, navigability and environmental conditions. The governing factors are the hydrodynamics of the two...

This report will study an oscillator with time-varying mass under the influence of rain-wind induced vibrations. The vibrations will satisfy an initial value problem with a nonlinear ordinary differential equation. The multiple time-scale perturbation method is used to solve the initial value problem. As the mass is set periodic in time with...

To keep up with the growing demand for oil and gas, the oil and gas industry ventures into deeper waters. For a deep water pipeline project, South Stream, a pipeline test program is developed. Part of this program is the investigation of the resistance of an externally pressurised pipeline against local buckling collapse. This is a decisive...

In this report I present the results from the mathematical analysis of a model neuronal network introduced by Ermentrout and Curtu, extended to two space dimensions. The model can be seen as a simple model of a cortical sheet that describes the firing rate activity of two populations of neurons coupled together, one excitatory that displays...

The Atrato River in Colombia should be navigable for bigger vessels when generating a corridor which should link the Atlantic Ocean with the Pacific Ocean. A likely segment of the river that forms a critical point for navigation is the point of bifurcation where the river is divided in the Montaño and Murindó branch. Both branches should be...

In 2000 the Dutch government chose a new point of view for the Dutch rivers: “Room for the River”. This viewpoint is the basis for a new approach of high water protection in the Netherlands. Instead of strengthening and raising the dikes, solutions must be based on space and spatial quality. One of the suggested measures is the addition of...

Assessment of the sodium/potassium (Na/K) pump functioning can play an important role in the early diagnosis of several polyneuropathies. However, currently no method exists that allows in vivo testing of the Na/K pump. Therefore, this study developed a test based on repetitive nerve stimulation at single motor units. In order to evaluate the Na...

The Westerschelde estuary in the South-West of the Netherlands displays two meandering flood and ebb channels separated by shoals. The system of flood, ebb channel and shoal between two channel crossings form a morphological cell. The stability of the serial cell system formed by the Westerschelde is important for the navigation route to the...
