Abstract:
Integration of material composition, microstructure, and mechanical properties with geometry information enables many product development activities, including design, analysis, and manufacturing. To address such needs, models of material composition have been integrated into CAD systems, creating systems called heterogeneous CAD modeling. In order to support the heterogeneous CAD system, extensive process-structure-property relationships have to be captured and integrated into current CAD system. A new method for reverse engineering of materials will be presented such that microstructure mode

La funzione valore è un nodo centrale del controllo ottimo. `E noto che la funzione valore può essere irregolare anche per sistemi molto regolari. Pertanto l’analisi non liscia diviene un importante strumento per studiarne le proprietà, anche grazie alle numerose connessioni con la semiconcavità. Sotto opportune ipotesi, la funzione valore è localmente semiconcava. Questa proprietà è connessa anche con la proprietà di sfera interna dei suoi insiemi di livello e dei loro perimetri. In questa tesi introduciamo l’analisi non-liscia e le sue connessioni con funzioni semiconcave ed insiemi di perim

Abstract:
In this thesis, structural optimization study is performed by using three different methods. In the first method, optimization is performed using MSC.NASTRAN Optimization Module, a commercial structural analysis program. In the second method, optimization is performed using the optimization code prepared in MATLAB and MSC.NASTRAN as the solver. As the third method, optimization is performed by using the optimization code prepared in MATLAB and analytical equations as the solver. All three methods provide certain advantages in the solution of optimization problems. Therefore, within the context

Abstract:
For repeated transient solutions of geometrically nonlinear structures the numerical effort often poses a major obstacle. Thus, the introduction of a reduced order model, which takes the nonlinear effects into account and accelerates the calculations considerably, is often necessary.This work yields a method that allows for rapid, accurate and parameterisable solutions by means of a reduced model of the original structure. The structure is discretised and its dynamic equilibrium described by a matrix equation. The projection on a reduced basis is introduced to obtain the reduced model. A compr

Abstract:
This thesis is concerned with the inverse problem of determining a unitary connection $A$ on a Hermitian vector bundle $E$ of rank $m$ over a compact Riemannian manifold $(M, g)$ from the Dirichlet-to-Neumann (DN) map $\Lambda_A$ of the associated connection Laplacian $d_A^*d_A$. The connection is to be determined up to a unitary gauge equivalence equal to the identity at the boundary. In our first approach to the problem, we restrict our attention to conformally transversally anisotropic (cylindrical) manifolds $M \Subset \mathbb{R}\times M_0$. Our strategy can be described as follows: we con

Cette thèse a pour objet l'étude des espaces classifiants pour les actions propres d'un groupe discret. La dimension géométrique propre est la plus petite dimension possible pour un tel espace (qui existe toujours). Nous montrons tout d'abord que pour un réseau dans le groupe d'isométries d'un espace symétrique de type non-compact sans facteur euclidien, la dimension géométrique propre est égale à la dimension cohomologique virtuelle. La preuve utilise le fait que si le rang réel de l'espace est supérieur ou égal à 2 et le réseau est irréductible, alors il est arithmétique. Dans ce cas, nous p

Abstract:
Space-time does an excellent job of describing a "when" and "where" of an event; however it fails to describe "what" was involved. Normally this is achieved by including quantum fields with their own labels and associated properties. Conservation of these properties is then achieved according to what experiment dictates. We propose to add additional coordinates to space-time that describe the "what" which is missing. We choose these coordinates to be complex anti-commuting Lorentz scalars and attach various quantum numbers to them as indicated by experimental observation. With 5 such coo

In this thesis we study certain geometric properties of Müntz spa- ces as subspaces of continuous functions. In the first chapter we present some of the most important examples of the Müntz type theorems. Namely, we present the classic Müntz theorem and the Full Müntz theorem in the setting of the space of continuous functions on the interval [0, 1]. We also mention several extensions of these theorems to the case of continuous functions on the general interval [a, b] as well as an analogy of the Full Müntz theorem for the Lp ([0, 1]) spaces.

Osteoporosis is a disease characterized by reduced bone mass and reduced bone quality. This deterioration manifests itself in osteoporotic fractures at skeletal sites containing large proportions of cancellous bone (ie. forearm, hip, spine). Given the costs associated with these fractures, improvements in our ability to model and predict the behaviour of cancellous bone would be of great financial and social benefit to society.
