1. Stress Distribution in Graded Cellular Materials Under Dynamic Compression
Abstract Dynamic compression behaviors of density-homogeneous and density-graded irregular honeycombs are investigated using cell-based finite element models under a constant-velocity impact scenario. A method based on the cross-sectional engineering stress is developed to obtain the one-dimensional stress distribution along the loading direction in a cellul

2. A estrutura argumental da língua karitiana: desafios descritivos e teóricos / Argument structure in Karitiana: theoretical and descriptive challenges
This masters thesis aims to describe the argument structure in Karitiana (Tupi branch, Arikém family, about 400 speakers) both in a theoretical and in a descriptive perspective. In this work, the challenge is to describe the verb classes identified in Karitiana in the formal theory of argument structure proposed by Hale and Keyser (2002). The work is divide

3. Person hierarchy in Avá Guarani : a study of distributed morphology / Hierarquia de pessoa em Avá Guarani : considerações a partir da morfologia distribuída
This master thesis describes and analyses morphological and syntactic processes related to person hierarchy in the Ava-Guaraní language (Tupi-Guaraní language family / Tupi stock). The work employs a general Generative framework, guided in particular by the principles of Distributed Morphology (HALLE; MARANTZ, 1993; HALLE, 1997; MARANTZ, 1997). Person hier

4. Composición de masas corporales de bailarinas de ballet y atletas de elite de deportes estéticos de Cuba
The level of scenic beauty of the ballet dancer figurine is determined by a set of morphofunctional characteristics that are exclusively valid for this modality. Female ballet dancers and aesthetic sport athletes share the characteristic of being slim and of efficiently executing the complex movements of their technical activities. The objective of this stud

5. Sub-actions for Anosov flows
Let (M, {Øt }) be a smooth (not necessarily transitive) Anosov flow without fixed points generated by a vector field X(x) = (d/dt)|t=0Øt (x) on a compact manifold M. Let A : M → R be a globally Holder function defined on M. Assume that ∫0T 0 A ◦ Øt (x) dt ≥ 0 for any periodic orbit {Øt (x)}t=T t=0 of period T . Then there exists a H¨older functi

6. On the aubry-mather theory for symbolic dynamics
We propose a new model of ergodic optimization for expanding dynamical systems: the holonomic setting. In fact, we introduce an extension of the standard model used in this theory. The formulation we consider here is quite natural if one wants a meaning for possible variations of a real trajectory under the forward shift. In other contexts (for twist maps, f

7. Clases de tropos como universales Ersatz
This work considers the program of reduction of universals by classes of resembling tropes. Several questions appear concerning the relation of resemblance: (1) Does not the "respects" for resemblance presuppose a universal? (2) Does not the fact that the relation of resemblance is a relation induce a vicious regress? (3) If there are different respects of c

8. About 3-manifolds supporting some actions of R POT. 2and a Morses conjecture / Sobre 3-variedades suportando certas ações de R POT. 2e uma Conjectura de Morse
First we consider a family of C POT. 2actions of R POT. 2on a closed 3-manifold. One of the conditions of this family is that it admits only a finite number of singular orbits, which are all diffeomorphic to circle. For this family we will give a description of the structure of the orbits as well the 3-manifolds supporting this actions. This generalizes resu

9. Dimensão de Hausdorff de ferraduras
Let f be a Cr diffeomorphism r ≥ 2 of a surface M2, and let ∆ a horseshoe of f (i.e, a transitive and isolated hiperbolic set). It is a classical result that exists a neighborhood U of such that for every diffeomorphism close to f in Cr topology the set ∆ g = ∩ gn (∪) is a horseshoe for g. We will prove a result of Mañé [3] th

10. Controles por seleção e rejeição em discriminações condicionais em humanos e pombos / Select control and reject control in conditional discriminations in humans and pigeons
O estudo do responder controlado por relações de seleção ou rejeição insere-se no âmbito de investigações sobre as condições necessárias e suficientes para a formação de classes de estímulos equivalentes. O presente projeto pretendeu investigar aspectos relacionados ao tema em experimentos conduzidos com humanos e pombos. O primeiro experiment

11. Implementação e análise de algoritmos BSP/CGM em um Beowulf e no InteGrade
As the science and technology advanced in all diverse areas, problems which require more and more computer power to be solved were risen. In the beginning, these problems were solved by high performance parallel computers which were huge and very expensive. After that, though, making clusters with PCs which worked together to offer a higher processing capaci

12. A não-atribuição de causalidade na Crônica Geral da Espanha de 1344 / The non- attribution of causality in Crônica Geral de Espanha de 1344
This work aims to characterize formally, semantically and pragmatically the passive, middle and impersonal constructions, in order to elucidate the nature of relation between these constructions in a archaic Portuguese, a relation observed in researches, such as those of Camacho (2002, 2003, 2006), in modern Portuguese. The present research, thus, claims tha
