<p>The objective of this work has been to study equilibrium and non equilibrium situations during high pressure gas processing operations with emphasis on utilization of the high reservoir pressure. The well stream pressures of some of the condensate and gas fields in the North Sea are well above 200 bar. Currently the gas is expanded to a specified processing condition, typically 40-70 bar, before it is recompressed to the transportation conditions. It would be a considerable environmental and economic advantage to be able to process the natural gas at the well stream pressure. Knowledge of t

Abstract:
This thesis is a study of non-equilibrium phenomena in quantum systems. Emphasis is given to the recently derived non-equilibrium fluctuation theorems, which relate the non-equilibrium response of a system to its equilibrium thermodynamic properties. We investigate the validity and importance of these theorems, from both a theoretical and experimental perspective, in systems ranging from a single atom to an ensemble of interacting particles. We also investigate the potential role of quantum dynamics in biological processes.

Abstract:
A consistent theory of non-equilibrium thermodynamics for Markovian open quantum systems has been developed in the late seventies in analogy with Classical Irreversible Thermodynamics. The time-evolution of these open systems is usually described by means of effective master equations in Lindblad form, that turn out to be reliable when there is a separation of time-scales between system and environment, such that memory effects are negligible and the so-called Markovian approximation is justified. In this framework, the variations of energy and entropy in the system are consistently described,

In this thesis we have thermodynamically characterized finite time processes performed on a colloidal particle, kept in contact with thermal reservoir(s). Thermodynamic processes are implemented on the colloidal particle by systematically changing the confining potential in a time dependent way, according to an external driving protocol or by controlling the environmental conditions over a finite duration. First, we study two externally driven systems: one in which the driving is deterministic, and another where the driving is stochastic. These models have appeared in the literature as the bui

Quantum information and quantum computing (QIQC) systems, relying on the phenomena of superposition and entanglement, offer the potential for vast improvements in certain computations. A practical QC realization requires maintaining the stored information for time-scales long enough to implement algorithms. One primary cause of information loss is decoherence, i.e., the loss of coherence between two energy levels in a quantum system. This work attributes decoherence to dissipation occurring as the system evolves and uses steepest-entropy-ascent quantum thermodynamics (SEAQT) to predict the evo

Toutefois, lorsqu'un défaut survient sur le réseau, il faut pouvoir couper le courant électrique. À cette fin, on utilise des appareils spécifiques comme les disjoncteurs haute-tension qui doivent être capables de couper l'arc électrique qui se forme lors de l'ouverture des contacts électriques. Afin de concevoir et d'améliorer les disjoncteurs, les industriels recourent de plus en plus aux modélisations numériques simulant le comportant de l'arc électrique e

Abstract:
Knowledge of free-energy differences for states of a system provides an essential component in understanding many processes, including solubility, reaction rates, and phase changes. Therefore, the development of efficient, accurate free-energy calculation routines has long been of interest within the field of molecular modelling. Until recently, thermodynamic integration, free-energy perturbation and slow-change techniques were the only approaches available for the calculation of free-energy differences between two states of a system. However, with the discovery of non-equilibrium free-energ

Abstract:
Le basi delle Leggi della Termodinamica stanno al centro della costruzione intellettuale della Fisica sin dalla loro prima formulazione alla fine del XIX secolo. A causa della loro centrale rilevanza, questi concetti suscitano ancora dibattiti molto accesi e alimentano feconde discussioni. Dato che questo è vero nel regno della fisica statistica dell'equilibrio - un corpus consolidato di concetti coerenti - la situazione è più instabile nella fisica statistica del non equilibrio, dove i dibattiti fondazionali sono ancora in corso. Questo stato di cose motiva lo studio dei fondamenti teorici e

Ziel der vorliegenden Arbeit ist es, das Preisach-Modell bezüglich stochastischer äußerer Felder und temperaturbezogener Aspekte zu untersuchen. Das phänomenologische Preisach-Modell wird oft erfolgreich angewendet, um Systeme mit Hysterese zu beschreiben. Im ersten Teil der Arbeit wird die Antwort des Preisach-Modells auf stochastische äußere Felder untersucht. Hier liegt das Augenmerk hauptsächlich auf der Autokorrelation; sie dient dazu den Einfluss des hysteretischen Gedächtnisses zu quantifizieren. Mit analytischen Methoden wird gezeigt, dass sich ein Langzeitgedächtnis, sichtbar in der A

Abstract:
La modélisation d'un disjoncteur haute tension par un modèle MHD nécessite des banques de données de propriétés du plasma afin de simuler le comportement de l'arc électrique. L'hypothèse d'équilibre thermodynamique local est souvent utilisée afin de calculer ces propriétés. Cependant les conditions d'équilibre ne sont pas remplies près des parois ou des électrodes, ou lors du passage par zéro du courant. Les écarts à l'équilibre (thermique notamment) modifient alors considérablement la chimie et les propriétés du plasma. L'étude de ces propriétés dans ces conditions nécessite alors de supposer

Un modèle constitutif complètement couplé est présenté pour l'analyse rigoureuse de la déformation, de l'écoulement de fluides et de transfert de chaleur dans les milieux poreux saturés à double porosité soumis à des chargements thermo-hydro-mécaniques, y compris ceux induisant un non-équilibre thermique local. La phase solide contient deux cavités distinctes: le bloc poreux et le réseau des fissures. Les équations de champs sont obtenues à partir des équations de conservation de la masse, du mouvement et de l'énergie et sont résolues par une approche par élément finis. Le modèle est utilisé p
