Abstract:

Mes travaux théoriques concernent les potentialités du microscope STM pour induire deux types d’excitations locales, soit vibrationnelle soit électronique, sur des molécules aromatiques isolées adsorbées sur des surfaces. La spectroscopie vibrationnelle sous le microscope à effet tunnel (IETS pour «Inelastic Electron Tunneling Spectroscopy») est une technique récente qui mesure le spectre vibrationnel d’une seule molécule déposée sur une surface conductrice. A partir d’une tension seuil, on peut exciter une vibration moléculaire qui se traduit par un pic dans la dérivée de la conductance par r

Depuis sa découverte, le graphène est devenu un centre de recherche et d'intérêt important en raison de ses caractéristiques mécaniques, thermiques et électriques exceptionnelles. Néanmoins, l'absence de bande interdite dans le graphène constitue un obstacle aux applications dans les domaines de l'optique, de la nanoélectronique et de la spintronique. L'ingénierie de la bande interdite impliquant la nanostructuration du graphène a été développée au fil des ans, par exemple par confinement quantique, pour surmonter cette limitation.

Using a fault-injection gate-level simulator and the generated test vector, all the faulty states of the circuit are simulated in parallel and the simulator is thus able to find all detected faults by a particular input sequence.

Abstract:

At voestalpine Precision Strip AB, the slitting process is used frequently. Slitting is a commonly applied manufacturing technique during sheet metal processing that aims to split large coils of sheet metal into narrower widths. The coiled sheets are uncoiled and transferred to a slitter, where they pass between rotating circular knives that produce long and straight cuts, splitting the wide sheet into desired widths. However, during operation, their slitting knives are occasionally damaged. This means that the knives must be replaced, which wastes both time and money. The goal of this proje

Abstract:

Simultaneous multithreading (SMT) processors can issue multiple instructions from distinct processes or threads in the same cycle. This technique effectively increases the overall throughput by keeping the pipeline resources more occupied at the potential expense of reducing single thread performance due to resource sharing. In the software domain, an increasing number of Dynamically Linked Libraries (DLL) are used by applications and operating systems, providing better flexibility and modularity, and enabling code sharing. It is observed that a significant amount of execution time in softwar

2007/2008<br>Il lavoro di ricerca è stato orientato allo studio delle proprietà delle strutture su grande scala dell'Universo. In particolar modo si sono studiate le proprietà ottiche e fisiche di popolazioni sintetiche di galassie in ammassi di galassie in ambito cosmologico all'interno dello scenario gerarchico. Abbiamo affrontato il problema della formazione galattica seguendo due approcci complementari. Una linea di ricerca svolta è stata indirizzata allo studio della popolazione galattica in ammassi di galassie, utilizzando simulazioni idrodinamiche cosmologiche. A tale scopo si sono a

Abstract:

Le procédé SLM offre de nouvelles perspectives en termes de conception de pièces. Cependant, les phénomènes thermo-mécaniques liés au procédé sont responsables des contraintes résiduelles et de la distorsion de la pièce fabriquée. La simulation numérique est un outil intéressant pour mieux cerner les phénomènes physiques à l’œuvre et leur impact sur la qualité de la pièce. Dans cette thèse, nous proposons différentes approches qui permettent de réaliser les simulations à moindre coût, en utilisant des algorithmes de réduction de modèles. Les résultats sont comparés à ceux obtenus par la méthod

Abstract:

L'objectif de la thèse présentée ici est l'optimisation de matériaux carbonésnanoporeux au moyen de la “conception de matériaux virtuels”. En ce qui concerne cette échelle de travail (~ 10nm), la Nanotomographie FIB-SEM est la seule technique d'imagerie donnant accès à une information sur la géométrie tridimensionnelle. Cependant, pour l'optimisation du comportement, l'espace des pores doit être reconstruit à partir des données tirées des images obtenues. Jusqu'à présent ce problème n'était pas résolu. Pour pouvoir le maîtriser, on a développé une simulation d'images FIB-SEM. Les images FIB-SE

Abstract:

Using Additive manufacturing it is possible to manufacture complicated components, that cannot be manufactured using conventional methods. The typical example is the lattice structure. Fabrication of these structures is complicated, and it is different from the fabrication of bulk parts. Using numerical simulation which can reflect process parameters it is possible to analyze the thermal behaviour of vertical and inclined struts fabrication. Results show that the diameter of struts influences weld track width. This influence is caused by preheating the powder material by previous scanning path

Abstract:

The thesis is focused on SCM and information support for supply chain managers with emphasis on modelling and simulation. The first main aim of the work is to verify the method for applicability in SCM problem solution. The second main aim is to analyse supply chains by means of modelling and simulation and find the most suitable supply chains for the area of The New economics. The third main aim is to analyse behaviour of supply chains under changing factors on which the supply chains are initially modelled. The output of this work is applicable in the theory, practice and education

Abstract:

This research has successfully developed an effective methodology to detect and locate deterioration as well as estimate its severity in the presence of environmental and operational (E&O) variations and high level of measurement noise. It developed a novel data normalization procedure to diminish the E&O variations and high level of noise content; and developed thirteen time-series based deterioration indicators to detect deterioration. The proposed methods were verified utilising measured data from different numerically simulated case studies and laboratory tests, and their efficiency is dem
