Testo completoNumerical simulations in the field of energetics often present sharp gradients or discontinuities, as well as strong disparity of spatial and temporal scales. This is typical of simulations runned with Cedre software, developed by ONERA’s Multi-physics department for energetics. All these features involve the development of accurate, robust and efficient numerical methods. In this framework, variable reconstruction is one of the key aspects of the resolution of hyperbolic conservation laws in finite volume methods. These reconstructions improve the accuracy of the numerical fluxes, which has a direct impact on the spatial accuracy of the scheme. Moreover, it is well known that a linear reconstruction is not sufficient to ensure the scheme stability. Thus, non-linear reconstructions are required. While scalar variables reconstructions have been intensively studied during the last decades, very few studies have been conducted on vectorial variable reconstructions. In industrial codes like Cedre, each component of vectorial variables is usually treated independently as a scalar variable. However, such an approach reveals to be frame-dependent : the solution is dependent on the frame, leading to conservation and accuracy problems on periodical meshes. This thesis therefore focuses on two aspects. Firstly, it aims to study theoretically the accuracy and stability of vectorial reconstructions, and secondly to develop a vectorial reconstruction method designed for the multislope MUSCL scheme, being efficient, accurate and robust. To do so, we introduce limited κ-schemes, allowing to obtain a second-order accurate frame-invariant reconstruction, easily adaptable to any monotone condition chosen. We also introduce fictitious reconstructions, allowing to get a formulation of the scheme highlighting its stability properties. We deduce from it two monotonicity definitions suitable for vectors, that we then run on different numerical test-cases. Lastly, we present a third approach, based on the direct extension of the scalar monotonicity condition to the vectorial case. Even if no stability proof has been written, this approach presents the best compromise between stability and accuracy

Resumo: Para percebermos como a noção de referencial é importante, considere a seguinte questão: qual seria a física de uma partícula num universo vazio? Qual seria sua velocidade, carga, temperatura, ou função de onda? Como seria sua evolução temporal? Embora seja um dos elementos mais básicos e fundamentais de uma teoria física, a não de referencial quase nunca é rigorosamente definida. Muitas vezes confunde-se com a noção de sistemas de coordenadas, uma entidade matemática abstrata e desprovida de substancia física. Um físico experimental, no entanto, tem a firme tendência de desaprovar esta noção. Por conseguinte, no final do século 20 e em anos recentes, alguns trabalhos investigaram a física descrita da perspectiva de referenciais físicos, de massa finita e interagentes. Entretanto, o conhecimento acumulado até o momento sobre este tópico, especialmente nas áreas de Relatividade Especial e Mecânica Quântica, é incipiente. Neste trabalho pretendemos contribuir para este contexto através de dois estudos preliminares em modelos simples da Física Moderna. Na primeira parte desta dissertação, revisitamos o problema da dilatação do tempo, onde atribuímos ao laboratório uma massa arbitrária de modo a participar das leis de conservação, pois este 'e capaz de "sentir" a emissão de um fóton; esta consideração acentua a fórmula usual por um fator adimensional envolvendo a constante de Planck. Na segunda parte, abordamos uma questão fundamental, qual seja: é a quanticidade total de recursos quânticos - coerências e correlações - invariante sob troca de referenciais quânticos? Nosso estudo 'e realizado em sistemas de poucas partículas onde, primeiramente, construímos e tratamos um modelo clássico "análogo" ao caso quântico para então tratarmos este 'ultimo; consideramos estados de posição e de spin descritos por referenciais distintos e avaliamos como os recursos comportam-se em cada referencial. Apesar da simplicidade dos modelos considerados, acreditamos que nossos resultados já sejam capazes de revelar aspectos sutis e importantes, merecendo então uma investigação mais aprofundada. Palavras-chave: relatividade especial, contração do tempo, referenciais leves, referenciais quânticos, correlações quânticas e coerência, spin relativo.
Abstract: In order to realize how the notion of reference frame is important, consider the following question: what would be the physics of a particle in an empty universe? What would its velocity, charge, temperature, or wave function be? What about its time evolution? Although it is one of the most basic and fundamental elements of a physical theory, the notion of reference frame is almost never rigorously defined. It is frequently confused with the notion of a coordinate system, an abstract mathematical entity devoid of physical significance. An experimental physicist, however, has the strong tendency to disapprove this notion. Therefore, at the end of the 20th century and in recent years, some works have investigated the physics described from the perspective of physical reference frames, of finitemass and interacting ones. However, the accumulated knowledge hitherto about this topic, specially in Special Relativity and Quantum Mechanics, is incipient. In this work we intend to contribute to this context through two preliminary studies regarding simple models from Modern Physics. In the first part of this dissertation, we revisit the time dilation problem, where we attribute to the laboratory an arbitrary mass so as to participate in the conservation laws, for it is able to "feel" the emission of a photon; this consideration accentuates the usual formula by a dimensionless factor involving the Planck constant. In the second part, we approach a fundamental question, which is: is the total quantumness of quantum resources - coherences and correlations - invariant under change of quantum reference frames? Our study is realized in systems composed of few particles where, firstly, we construct and treat a classical model which is "analog" to the quantum case and only then we attend to the latter; we consider position and spin states described by distinct reference frames and evaluate how the resources behave in each frame. Despite of the simplicity of the approached models, we believe that our results are already able to reveal subtle and important aspects, deserving then a more profound investigation. Keywords: special relativity, time contraction, lightweight reference frames, quantum reference frames, quantum correlations and coherence, relative spin.

Testo completoIn the field of software verification, the frame problem refers to establishing the boundaries within which program elements operate. It has notoriously tedious consequences on the specification of frame properties, which indicate the parts of the program state that an operation is allowed to modify, as well as on their verification, i.e. proving that operations modify only what is specified by their frame properties. In the context of interactive formal verification of complex systems, such as operating systems, much effort is spent addressing these consequences and proving the preservation of the systems' invariants. However, most operations have a localized effect on the system and impact only a limited number of invariants at the same time. In this thesis we address the issue of identifying those invariants that are unaffected by an operation and we present a solution for automatically inferring their preservation. Our solution is meant to ease the proof burden for the programmer. It is based on static analysis and does not require any additional frame annotations. Our strategy consists in combining a dependency analysis and a correlation analysis. We have designed and implemented both static analyses for a strongly-typed, functional language that handles structures, variants and arrays. The dependency analysis computes a conservative approximation of the input fragments on which functional properties and operations depend. The correlation analysis computes a safe approximation of the parts of an input state to a function that are copied to the output state. It summarizes not only what is modified but also how it is modified and to what extent. By employing these two static analyses and by subsequently reasoning based on their combined results, an interactive theorem prover can automate the discharching of proof obligations for unmodified parts of the state. We have applied both of our static analyses to a functional specification of a micro-kernel and the obtained results demonstrate both their precision and their scalability
