Abstract:
This work studies the extension problem for subsets of finite fields. This remains an important unsolved problem in harmonic analysis, in both the Euclidean and finite field setting. We survey the partial results obtained to date, common techniques, and open conjectures. In the case of a homogeneous variety H over a d-dimensional finite field, the L² to L⁴ boundedness is proved whenever H contains no hyperplanes. This is accomplished by proving an incidence theorem for cones of this type, and applying a sufficient condition for L² to L²m obtained by Mockenhaupt and Tao in their 2004 introducto

Abstract:
Let X be a space and let S ⊂ X with a measure of set size |S| and boundary size |∂S|. Fix a set C ⊂ X called the constraining set. The constrained isoperimetric problem asks when we can find a subset S of C that maximizes the Følner ratio FR(S) = |S|/|∂S|. We consider different measures for subsets of R^2,R^3,Z^2,Z^3 and describe the properties that must be satisfied for sets S that maximize the Folner ratio. We give explicit examples.

Abstract:
The 4D low-energy limit of string compactifications is characterised by the ubiquitous presence of string moduli which are new gravitationally coupled scalar fields which develop mass via supersymmetry breaking effects. During inflation it is generically expected that these fields receive large contributions to their mass of order the Hubble constant. They are therefore shifted from their minimum and after the end of inflation start oscillating around it behaving as non-relativistic matter. Given that matter redshifts slower than radiation, the moduli quickly come to dominate the energy densit

Abstract:
This thesis is a critical examination of phenomenological nuclear mean field theories, focusing on reliable description of levels of individual particles. The approach presented here is new in the sense that it not only allows to predict the numerical values obtained with this formalism, but also yields an estimate of the probability distributions corresponding to the experimental results. We introduce the concept of 'theoretical errors' to estimate uncertainties in theoreticalmodels. We also introduce a subjective notion of 'Predictive Power' of nuclear Hamiltonians, which is analyzed in the

We show that the inclusion of the second order derivative with the Dirac delta function in the series improves the agreement of the result. Generally, at any order the agreement b

Theories with a chemical potential are difficult to treat numerically because the action is complex and therefore methods based on a probability interpretation of the weight break down. This is an issue known as the sign problem. Complex Langevin dynamics was first proposed in the early 1980s and does not rely in a probability interpretation of the weight, so it can in principle l)e applied even where there is a severe sign problem.

Agricultural producers consider utilizing multiple machines to reduce field completion times for improving effective field capacity.

However, machinery management is complicated due to logistics issues.

Derivatives of the forward operator are considered and the solution of the inverse problem via a least-squares minimization is introduced.

Abstract:
Étant donné 2n points, n ``rouge'' et n ``bleu'', dans un espace euclidien,la résolution du problème d'assignation euclidienne associé consiste à trouver la bijection entre les points rouges et bleus qui minimise une fonctionnelle des positions de points. Dans la version stochastique de ce problème, les points sont un processus de point de Poisson, et un certain intérêt a développé au fil des ans sur les propriétés typiques et moyennes de la solution dans la limite n to ∞. Cette thèse de doctorat porte sur ce problème dans un certain nombre de cas (;plusieurs résultats exacts en d=1, la dériva

Abstract:
Current research on knowledge integration offers valuable structural analyses of factors that influence knowledge integration, performance outcomes, and knowledge integration mechanisms. Less attention has been paid to how knowledge integration is carried out over time in cross-functional development projects. This thesis is based on a year-long field study of an Information Systems Development Project. The study shows how the knowledge integration process was repeatedly interrupted by different problems that could not be resolved by merely relying on integration mechanisms that were imposed b

Abstract:
In contemporary software development, an emergent understanding of the problem domain and envisioned goals forms the basis of designing, testing and development activities. Lack of a common understanding of the domain can result in costly rework or client dissatisfaction. Research shows that the development of shared understanding in this context is a complex and error-prone process and there is room for improvement. Is this because practitioners are not following suggested practice from literature? Or are the actual barriers to shared understanding not being addressed by current tools and tec

Abstract:
Dans cette thèse, nous étudions la possibilité de sonder des degrés de liberté lourds encore inconnus de la Nouvelle Physique par le biais de processus de basse énergie médiés par des courants neutres changeant la saveur. Nous les analysons dans le cadre des théories des champs effectives afin de tirer parti de la séparation des échelles d'énergie impliquées. Nous nous concentrons sur des processus du Modèle Standard qui ont déjà été observés et qui sont particulièrement sensibles aux effets de la Nouvelle Physique (b → s γ), ou sur des processus interdits dans le Modèle Standard dont l'observ
