Four journal papers have been selected from the candidate's published research output, to represent his work in developing analytical methods for use in geotechnical engineering design and analysis. Two of the papers contribute to significant advances in the understanding of the behaviour of dry-stone retaining walls, which will lead to greater confidence in the assessment of existing walls and the design of new walls. The other two papers develop optimisation and analysis routines with the aim of supporting the assessment of slope stability, and the design of new cut and built slopes and stab

Resumen

Limit equilibrium methods are widely and routinely used in practice. In several codes, limit equilibrium methods are recommended to evaluate the stability of a lateral support systems, such as soil-nails and anchors, to an acceptable defined factor of safety. For decades, limit equilibrium methods have been used successfully in providing an acceptable margin of safety against failure (movements, which can be significantly more complex, is not considered). However, due to the advances in computational power offered by personal computers, finite element modelling has become increasingly ac

Resumen

In this research, extensive use has been made of limit equilibrium methods of analysis for studying the stability of slopes. For the determination of the factor of safety (FOS) of slopes, the usual two-step process has been adopted; (a) assuming a slip surface for the soil mass, and (b) using the appropriate limit equilibrium equation(s). Eight wellknown limit equilibrium methods have been programmed to calculate different FOS values. The comparative performance of the various analyses has been carried out successfully using case studies. The innovative use of Gauss quadrature to calculate the

Resumen

The slope instability occurred in Pos Selim since 1997. Several cut back of the slope had been carried out, however, the instability of the slope was still occurred. In 2006, the head of the slope was moved for 2m. This raises the concern on the failure mechanism of the slope. In this study, slope stability analysis with Limit Equilibrium Method (LEM) was carried out. In view of the interslice shear could play an important role to the overall slope stability, SARMA’s method was adopted in the study.

Resumen

Two-dimensional limit equilibrium types of analysis have been used in engineering practice for decades and are the most commonly adopted analysis technique for assessing the stability of slopes. These methods compute a factor of safety based on a comparison of available to required shear strength along a prescribed failure surface. Forces and static equilibrium conditions are only considered in the plane of movement. However, in reality, all slope failures occur in three-dimensions. Every sliding mass has a finite length and shear forces acting at the lateral extents of the mass contribute to

Resumen

An den Handelsbörsen der Welt, hat der Anteil unsichtbarer Luidität in den letzten Jahren dramatisch zugenommen. Obwohl dieser Trend zunehmend in den Fokus regulatorischer Debatten und akademischer Dikussionen rückt, sind sich Forscher und die Aufsichtsbehörden über die Implikationen und entsprechende regulatorische Maßnahmen uneins. In der vorliegenden Arbeit, werden die damit verbundenen Fragestellungen in drei separaten Kapiteln theoretisch und empirisch untersucht. Mit Hilfe eines speziellen NASDAQ Datensatzes, werden in Kapitel 1 die Marktfaktoren, die unsichtbaren Liquidität begünsti

Resumen

La stabilité des exploitations à ciel ouvert (mines ou carrières) excavées dans des massifs rocheux dépend de leur géométrie, des caractéristiques géométriques de la fracturation (orientation et espacement) du massif et des caractéristiques mécaniques du massif et des discontinuités. L'évaluation du risque d'instabilité rocheuse dépend de la quantité et la qualité des informations disponibles sur le massif rocheux et des méthodes d'analyse mises en œuvre pour évaluer le comportement mécanique de l'assemblage de blocs rocheux. Différents sites de talus naturels, d'excavation routière et de carr

Resumen

L'obiettivo di questa tesi è quello di applicare alcune nozioni tipiche dei sistemi dinamici discreti a una situazione economica. Si considerano vari casi di oligopolio, secondo il modello di Cournot, e si osserva che un sistema di n competitori inizia a essere instabile con l'aumentare di n. Si approfondisce poi il caso di un duopolio simmetrico in cui i competitori hanno limitate capacità produttive. Se ne studiano i punti di equilibrio e la loro stabilità e, considerando la funzione di reazione, si osserva che le variazioni degli attrattori prodotte da cambiamenti dei parametri nella funzio

Resumen

Mean field games represent limit models for symmetric non-zero sum dynamic games when the number N of players tends to infinity. In this thesis, we study mean field games and corresponding N- player games in continuous time over a finite time horizon where the position of each agent belongs to a finite state space. As opposed to previous works on finite statemean field games, we use a probabilistic representation of the system dynamics in terms of stochastic differential equations driven by Poisson random measures. Firstly, under mild assumptions, we prove existence of solutions to the mean fi

Resumen

Doutoramento em Economia<br>Modelos de equilíbrio geral são largamente usados na academia e em instituições internacionais. Aqui, questões relacionadas com reformas estruturais, o limite inferior das taxas de juro e sua relação com opções de política são analisadas com um modelo de larga escala. Os principais resultados são: reformas estruturais unilaterais são benéficas e coordenação nacional tem vantagens; com as taxas de juro no limite inferior, políticas orçamentais e estruturais podem aliviar uma recessão e reduzir o tempo em que esse limite é activo. Mas a eficácia depende do instrumento

Resumen

Il lavoro esamina il comportamento sismico delle opere di sostegno rigide attraverso un approccio multi-blocco. Dopo un'ampia revisione dello stato dell'arte una prima parte del lavoro descrive alcune soluzioni in forma chiusa determinate per la valutazione del coefficiente sismico critico e del coefficiente di spinta attiva per schemi muro-terreno caratterizzati da differenti condizioni di carico e al contorno. La seconda parte del lavoro riguarda l'analisi agli spostamenti effettuata attraverso un approccio multi-blocco che tiene conto del possibile cambio di geometria del sistema con il pro

Resumen

Nous nous intéressons dans cette thèse à la théorie cinétique et aux systèmes de particules dans le cadre des équations de Boltzmann et Landau. Premièrement, nous étudions la dérivation des équations cinétiques comme des limites de champ moyen des systèmes de particules, en utilisant le concept de propagation du chaos. Plus précisément, nous étudions les probabilités chaotiques sur l'espace de phase de ces systèmes de particules : la sphère de Boltzmann, qui correspond à l'espace de phase d'un système de particules qui évolue conservant le moment et l'énergie ; et la sphère de Kac, corresponda

Resumen

Les simulations numériques directes (DNS) des couches limites supersoniques adiabatiques et isothermes (chauffées et refroidies) sont effectuées. Deux différents scénarios de transition, à savoir la décomposition de type oblique et la transition de type 'by-pass', sont présentés en détail. Pour le scénario de transition de type oblique, les résultats montrent que les modes contrôles avec un nombre d'onde quatre à cinq fois supérieur au nombre fondamental se révèlent être bénéfiques pour contrôler la transition. Dans la première région après le forçage du mode de contrôle, la distorsion de flux
