Cette thèse a pour l'étude des principes d'incertitude et des problèmes d'approximation en analyse de Fourier. Elle se compose de deux parties. La première partie se concentre sur les principes d'incertitude dans l'analyse de Fourier. En utilisant une technique récemment inventée par Avi Wigderson et Yuval Wigderson, nous donnons une nouvelle preuve du principe d'incertitude de Heisenberg, répondant ainsi positivement à plusieurs questions posées par Wigderson & Wigderson. Nous obtenons également des nouvelles généralisations du principe d'incertitude, qui illustre la puissance de la nouve

Abstract:

In this thesis we investigate some global desiderata for probabilistic knowledge merging given several possibly jointly inconsistent, but individually consistent knowledge bases. We show that the most naive methods of merging, which combine applications of a single expert inference process with the application of a pooling operator, fail to satisfy certain basic consistency principles. We therefore adopt a different approach. Following recent developments in machine learning where Bregman divergences appear to be powerful, we define several probabilistic merging operators which minimise the jo

Abstract:

The engineering design community recognizes that an essential part of the design process is decision making. Because decisions are generally made under uncertainty, engineers need appropriate methods for modeling and managing uncertainty. Two important characteristics of uncertainty in the context of engineering design are imprecision and irreducible uncertainty. In order to model both of these characteristics, it is valuable to use probabilities that are most generally imprecise and subjective. These imprecise probabilities generalize traditional, precise probabilities; when the available

Abstract:

Wireless sensor networks are attractive largely because they need no wired infrastructure. But precisely this feature makes them energy constrained, and the consequences of this hard energy constraint are the overall topic of this thesis. We are in particular concerned with principles for energy efficient wireless communication and the energy-wise trade-off between sensing and radio communication. Radio transmission between sensors incurs both a fixed energy cost from radio circuit processing, and a variable energy cost related to the level of radiated energy. We here find that transmission te

Abstract:

When we observe or use something, its property seems to change because of the way we establish relationships with it. Inspired by the Uncertainty Principle – a physical theory published by Heisenberg in the year of 1927 – I take both people and objects as something always in an uncertain status. We cannot fully define objects, but only try to understand and live with it in a complex and constantly changing context.Three pieces of furniture are created to visualize the idea about how the relationships between people and objects could be from this viewpoint, exploring how far away people could a

We investigate principles of rationality based on symmetry in Polyadic Pure Inductive Logic.

This thesis centres on principles arising from instances of symmetry for sentences of first-order polyadic languages. We begin with the recently introduced Permutation Invariance Principle (PIP), and find that it is determined by a finite number of permutations on a finite set of formulae.

The robustness issue is a direct result of the uncertain measurements and the lack of experimental control that axe characteristic of HVAC systems. This thesis investigates the uncertainties

We propose and investigate several new principles of rational reasoning within the framework of Pure Inductive Logic, PIL, where probability functions defined on the sentences of a first-order language are used to model an agent's beliefs. The Elephant Principle is concerned with how learning, modelled by conditioning, may be uniquely `remembered'. The Perspective Principle requires that, from a given prior, conditioning on statistically similar experiences should result in similar assignments, and is found to be a necessary condition for Reichenbach's Axiom to hold.

Abstract:

Typically, design is approached as a sequence of decisions in which designers select what they believe to be the best alternative in each decision. While this approach can be used to arrive at a final solution quickly, it is unlikely to result in the most-preferred solution. The reason for this is that all the decisions in the design process are coupled. To determine the most preferred alternative in the current decision, the designer would need to know the outcomes of all future decisions, information that is currently unavailable or indeterminate. Since the designer cannot select a single a

Abstract:

Les problèmes de quantification d'incertitudes des modèles numériques nécessitent de nombreuses simulations, souvent très coûteuses (en temps de calcul et/ou en mémoire). C'est pourquoi il est essentiel de construire des modèles approchés qui sont moins coûteux à évaluer. En pratique, si la réponse d'un modèle numérique est représentée par une fonction, on cherche à en construire une approximation.L'objectif de cette thèse est de construire l'approximation d'une fonction qui soit contrôlée tout en utilisant le moins d'évaluations possible de la fonction.Dans un premier temps, nous proposons un

Abstract:

Kemikalier utgör en grundläggande beståndsdel av det senindustriella samhället, och en omfattande produktion av kemikalier brukar allmänt anses som en nödvändig förutsättning för teknisk utveckling och ekonomisk tillväxt. I Sverige ledde miljölarmen om DDT, PCB och kvicksilver på 1960- och 1970-talet till inrättandet av ett system för kemikaliekontroll som brukar framhållas som ett av världens främsta. Avhandlingen undersöker detta kontrollsystem och dess logik. Detta görs genom textanalys av propositioner, statliga utredningar, rapporter från Naturvårdsverket och Kemikalieinspektionen, samt g

Introdução - Desde a década de 70 a sociedade contemporânea depara-se com riscos e incertezas que apresentam características únicas. Casos emblemáticos nos campos da saúde, segurança e meio ambiente são discutidos pela mídia, organizações não-governamentais, governos, empresas e sociedade civil, e sobre eles o direito é chamado a se posicionar. Para lidar com esses temas, ao longo das duas últimas décadas o direito (internacional e do ambiente) construiu o princípio da precaução. Objetivo - A pesquisa tem por objeto discernir o que o princípio da precaução tem sido, do que ele não é, e o que e

Abstract:

We apply the Segal process of group simplification to the linear harmonic oscillator. The result is a finite quantum theory with three quantum constants instead of the usual one. We compare the classical (CLHO), quantum (QLHO), and finite (FLHO) linear harmonic oscillators and their canonical or unitary groups. The FLHO is isomorphic to a dipole rotator with N=l(l+1) states where l is very large for physically interesting case. The position and momentum variables are quantized with uniform finite spectra. For fixed quantum constants and large N there are three broad classes of FLHO: soft, med

Abstract:

This thesis aims to discuss some of the relationships between oscillation theory for linear ordinary differential equations on the real line (shortly, ODE) and the geometry of complete Riemannian manifolds. In this respect, we prove new results in both directions. For instance, we improve on classical oscillation and nonoscillation criteria for ODE's, and we find sharp spectral estimates for a number of geometric differential operator on Riemannian manifolds. We apply these results to achieve topological and geometric properties. In the first part of the thesis, we collect some material which
