Abstract:

Rapid development in nanofabrication has led to the design of new materials with very unusual properties. The exhibition of negative and zero indices of refraction are among the most striking properties of these materials, which have become the focus of intensive research worldwide. The potential for applications that is possible due to the new light manipulation capabilities of these materials has been the driving force behind this research. Most of the research in this field has primarily been experimental while the theoretical studies have mainly been limited to computer modeling, which

Abstract:

High cycle fatigue tests were carried out on a medium strength continuous casting AA 5754 Al alloy, and new generation high strength AA 2026 and AA 2099 Al alloys. The effect of texture on fatigue properties and short crack behavior were studied. The strengthening mechanisms were also thoroughly investigated for the two high strength alloys.Texture played an important role in the anisotropy of fatigue strength for the AA 5754 Al alloy. Being a solution strengthened alloy, it had a fatigue strength of 120% σy. High strength Al alloys had a strong tendency for planar slip due to the high density

Abstract:

En raison du grand nombre de graphes de connaissances et, surtout, de leurs interconnexions encore plus nombreuses à l'aide de la propriété owl:sameas, il est devenu de plus en plus évident que cette propriété est souvent mal utilisée. En effet, les entités liées par la propriété owl:sameas doivent être identiques dans tous les contextes possibles et imaginables. Dans les faits, ceci n'est pas toujours le cas et induit une détérioration de la qualité des données. L'identité doit être considérée comme étant dépendante d'un contexte. Nous avons donc proposé une étude à large échelle sur la prése

Abstract:

This research consists of two main parts: development of a rock expert system (RES) as an easy-to-use and effective tool for evaluating rock properties, and modification and utilization of the three-dimensional Particle Flow Code (PFC3D) to analyze rock behavior. Because of different reasons, it is often difficult to obtain the rock property values directly. As an alternative, typical values and empirical correlations are often used to evaluate the rock property values. However, the typical values and empirical correlations come in various forms and are scattered in different sources. It is of

Abstract:

Increasing societal demand for automation has led to considerable efforts to control large-scale complex systems, especially in the area of autonomous intelligent control methods. The control system of a large-scale complex system needs to satisfy four system level requirements: robustness, flexibility, reusability, and scalability. Corresponding to the four system level requirements, there arise four major challenges. First, it is difficult to get accurate and complete information. Second, the system may be physically highly distributed. Third, the system evolves very quickly. Fourth, emergen

Abstract:

La quantification et la propagation des incertitudes dans les modèles physiques apparaissent comme des voies essentielles vers l'amélioration de la prédiction de leur réponse. Le développement d'outils de modélisation des incertitudes et d'estimation de leur impact sur la réponse d'un modèle a constitué un axe de recherche privilégié dans de nombreux domaines scientifiques. Cette dernière décennie, un intérêt croissant a été porté à des méthodes numériques basées sur une vision fonctionnelle des incertitudes. Ces méthodes, couramment baptisées ``méthodes spectrales stochastiques'', sont issues

Abstract:

This Thesis is devoted to the study of two different aspects of electron behavior in two-dimensional materials, namely hydrodynamic electron transport and plasmon propagation. The Thesis is structured as follows. In Chapter 1 the main experimental facts that motivated our work on electron hydrodynamics and plasmonics are presented and critically discussed. Chapter 2 contains our main results on hydrodynamic electron transport. After deriving the basic equations of the electron hydrodynamics and discussing their limit of applicability, we use them to quantify the impact of two different tr

Abstract:

Tissue healing is in general a complex process, which involves both local and systemic responses, and bone regeneration in particular is much slower than repair in any other human tissue. Thus, it exhibits a great challenge in clinical practice and in the field of research. Bone regeneration is comprised of a series of biological events, involving a number of cell types and intracellular and extracellular molecular- signaling pathways, with a definable temporal and spatial sequence, in an effort to optimize the skeletal repair and restore its functionality.

But in the case of loopy graph, it would cause some problem if we use the belief propagation to evaluate beliefs. There are some results for correcting those problems in the case of single loop, and those results were made by Weiss in [11]. In this paper, we use those results in [11] to solve another case, which has two single loops connected by a singly connected sub-graph. In the end, we attempt to apply Loopy

Abstract:

Inverse problems are very challenging as these problems involve, finding the cause by analyzing the effects. In structural dynamics problems, the effects are normally measured in terms of dynamic responses in structures. These responses which are used to find the cause generally have partial data, embedded with measurement noise, and are truncated. Due to these problems, inverse problems are generally ill-posed in most cases as against forward problems. In this dissertation, we solve five different types of inverse problems involving high-frequency transient loads. All these problems are sol

Abstract:

The specialized myocytes of the ventricular conduction system (VCS) coordinate ventricular contraction and are critical for efficient pumping by the heart. Impaired VCS conduction is characteristic of inherited forms of cardiac conduction disorders. Here we show that the Iroquois homeobox 3 (Irx3) transcription factor is preferentially expressed in the developing and mature VCS. Loss of Irx3 in mice results in slowed VCS conduction and prolonged QRS duration with right bundle branch block, caused by reduction (42%) in VCS-specific connexin 40 (Cx40) expression and VCS fiber hypoplasia, absent
