Abstract:
Cette thèse présente une famille de schémas explicites pour la résolution d'un problème couplé d'interaction entre un fluide visqueux incompressible et une structure élastique (avec possiblement un comportement visco-élastique et/ou non linéaire). La principale propriété de ces schémas est une condition de Robin consistante à l'interface, qui représente une caractéristique fondamentale du problème continu dans le cas où la structure est mince. Si le couplage s'effectue avec une structure épaisse, une condition de Robin généralisée peut être formulée pour le problème semi-discret en espace, à l

Abstract:
Soil-pile-structure interaction analysis is the simultaneous consideration of the structural frame, pile foundations, and the soil forming the founding material. Failure to consider soil-pile-structure interaction in design will lead to a poor prediction of load distribution within the structure. A poor prediction of load distribution will cause the structure to deform under loads that have not been calculated for. This may result in the structure cracking or the overstressing of columns. If the actual load distribution significantly differs from that designed for, the factor of safety on stru

Abstract:
Offshore structures are required to survive in extreme wave environments. Historically, the design of these offshore structures and vessels has relied on wave-tank experiments and linear theory. Today, with advances in computing power, it is becoming feasible to supplement these methods of analysis with fully nonlinear numerical simulation. This thesis is concerned with the development of an efficient method to perform this numerical modelling, in the context of potential flow theory.

Abstract:
Numerical algorithms for efficiently solving optimal control problems are important for commonly used advanced control strategies, such as model predictive control (MPC), but can also be useful for advanced estimation techniques, such as moving horizon estimation (MHE). In MPC, the control input is computed by solving a constrained finite-time optimal control (CFTOC) problem on-line, and in MHE the estimated states are obtained by solving an optimization problem that often can be formulated as a CFTOC problem. Common types of optimization methods for solving CFTOC problems are interior-point (

Modelling galaxy formation in a cosmological context is challenging due to many physical processes and a wide range of scales involved. It is then convenient to address the problem by means of numerical techniques.

The treatment of the interstellar medium, with multiple gas phases co-existing at very different densities and temperatures, needs to be included in simulations in the form of sub-resolution effective models.

The associations between numerical cognition and memory processes in relation to the working memory model of Baddeley (1986) were investigated. The first study used the factor analytic method to elucidate the factor structure of the processes that underlie numerical cognition, and to investigate the various components of the working memory model in relation to arithmetic.

Current dynamic testing methods can prove unrealistic due to the scale at which test components are modelled, the rate at which they are loaded or the boundary conditions to which they are subjected. A new test method, termed "Real-Time Sub-Structure Testing" seeks to provide a more realistic testing environment for energy dissipative components. The method tests structural components at full or large scale and in real-time. The physical test interacts with a computer model of the structure surrounding the test component. In this way, the in-situ behaviour of the test component is evaluated in

Abstract Liquid containing tanks (LCTs) are used in water distribution systems and in the industry for storing water, toxic and flammable liquids and are expected to be functional after severe earthquakes. The failure of a large tank during seismic excitation has implications far beyond the economic value of the tanks and their contents. Then seismic design becomes a high necessity for this type of structure. However, tanks differ from buildings in two ways: first, during seismic excitation, the liquid inside the tank exerts a hydrodynamic force on tank walls, base, and roof in addition to the

One of the most common advanced control strategies used in industry today is Model Predictive Control (MPC), and some reasons for its success are that it can handle multivariable systems and constraints on states and control inputs in a structured way.

Thesis (Ph.D.)--Wichita State University, College of Engineering, Dept. of Aerospace Engineering<br>Cardiovascular disease (CVD) is the number one cause of death in the United States and worldwide. Among the various CVDs, coronary artery disease (CAD) is the leading cause of death among both men and women. Of the various forms of CADs, atherosclerosis is the primary cause. To investigate these arterial diseases, numerical simulations of blood flow in the arteries using fluid-structure interactions (FSI) with the finite element method were performed. First, simulations were performed assuming t

Abstract:
L'imagerie par résonance magnétique de diffusion (IRM de diffusion) est une modalité d'imagerie non invasive couramment utilisée pour mesurer les propriétés micro-structurales des tissus biologiques au dessous de la résolution spatiale, en mesurant indirectement le déplacement de diffusion des molécules d'eau. En raison de la complexité géométrique du cerveau et du mécanisme complexe de l'IRM de diffusion, il est difficile de relier directement les signaux reçus à des paramètres biophysiques significatifs, tels que le diamètre des axones ou la densité. Ces dernières années, plusieurs modèles b

Abstract:
The growth of the nuclear power industry has provided a considerable stimulus for investigations into fluid-structure interaction problems. The safety case for nuclear reactors requires an understanding of the impact response of structures enclosing or surrounded by fluids. In many cases the structural response is in excess of that which can be predicted by elastic analyses and both material and geometrical non-linearities must be considered. The understanding of the interaction between the structure and the contained fluid poses additional problems which, in the extreme loading conditions env

Abstract:
A numerical case study of a multistage compressor with relative supersonic rotors is presented. The purpose of the investigation was to determine the flow instability mechanism of the UEET compressor and its relation to the rotor shock structure in the relative velocity reference frame. The computational study was conducted with the NASA code ADPAC , utilizing the mixing-plane assumption for the boundary condition between adjacent, relatively-rotating blade rows. A steady, five-blade-row, numerical simulation using the Baldwin-Lomax turbulence model was performed, creating several constant spe
