1. Entre mecánica cuántica y estructuras químicas: ¿a qué refiere la química cuántica?
The aim of this article is to address the question of the ontology of quantum chemistry. To this end we will focus on the concept of chemical bond, from the perspective of the two approaches by means of which the Schrödinger equation is applied to molecular chemical systems: the Theory of Valence Bond (VB) and the Theory of Molecular Orbital (MO). On the ba

2. A categoria computável dos espaços coerentes gerados por conjuntos básicos com aplicação em análise real / The computable category of the coherence spaces generated by basic sets with an application in real analysis
Neste trabalho desenvolve-se um estudo sobre os Espaços Coerentes Gerados por Conjuntos Básicos, dotados de uma estrutura adicional. Por estrutura adicional entende-se uma estrutura algébrica, de ordem pontual, de medidas, topológica e lógica. Estes espaços, denotados por , constituem uma subcategoria dos Espaços Coerentes, cujos objetos, ordenados pe

3. Simulador de meios porosos saturados elastoplasticos / Numerical simulator of saturated elastoplastic porous media
The exploration of mineral resources is growing in importance in the Brazilian economy. Since the environments in which these resources are found are becoming increasingly more complex and challenging for the production phase, currently unavailable knowledge and technologies are required to produce these reserves. In the particular well drilling and completi

4. Soluções analíticas da equação de Burgers aplicada à formação de estruturas no Universo
The Burgers equation has been applied to several fields of scientific knowledge, and particularly to the study of formation of structures in Universe. His relevancestillincreases, duetothewealthofobservationaldatainmodernliterature. His most general form is the generalized Burgers equation with noise as proposed for Ribeiro and Peixoto de Faria [24]. The kno

5. Uma investigação sobre paradigmas tecnológicos e abordagens pedagógicas dos tutores inteligentes nos sistemas de ensino-aprendizagem
This research work has as its starting point the conjecture posed by Oliveira regarding a possible technicist reflux yielded by the dissemination of new information and communication technologies (ICTs) over varying extents (political, economical, scientific etc.), highlighting its incidence on the implementation of its resources in the domain of the methods

6. Infra-estrutura de componentes paralelos para aplicaÃÃes de computaÃÃo de alto desempenho / Infrastructure of parallel components for applications of computation of high performance
The development of new High Performance Computing (HPC) application has demanded a set of tools for reconciling high level of a abstraction with software integration. In particular, we are interested in component-based solutions presented by the scientific community in the last years. Components have been applied to meet new requirements of high performance

8. Implementation of a plant-associated bacteria proteome database:ProBacter / Implementação de um banco de dados de proteomas de bactérias associadas a plantas: ProBacter
This dissertation offers a computation approach to comparative analysis between cmpletely sequenced genomes of plant-associated bacteria. The created system was denominated ProBacter and it is composed of a relational database and computational tools for sequence analysis. The database was created from a diverse data source, including information from GenBan

9. Fluid animation by cellular automata and particles systems / Animação de fluidos via autômatos celulares e sistemas de partículas
The past two decades showed a rapid growing of physically-based modeling of fluids for computer graphics applications. Techniques in the field of Computational Fluid Dynamics (CFD) have been applied for realistic fluid animation for virtual surgery simulators, computer games and visual effects. In this approach, since the equation is solved numerically the n

10. Development of particle method representing floating bodies with highly non-linearwaves. / Desenvolvimento do método de partículas na representação de corpos flutuantes em ondas altamente não-lineares.
O método numérico para fluidos incompressíveis desenvolvido no presente estudo é o Moving Particle Semi-Implicit Method (MPS) que enxerga o domínio discretizado em partículas, é baseado em representação lagrangeana e não tem a necessidade de utilização de malhas. O método MPS tem como equações governantes uma forma particular da equação de N

12. Técnicas de orientação ao objeto para computação científica paralela / Object orinted techniques for parallel scientific computing
Neste trabalho apresentamos a metodologia de orientação ao objeto no desenvolvimentos de uma biblioteca de classes para facilitar o processo de programação numérica paralela. Na implementação dos métodos das classes utilizamos as rotinas do pacote ScaLAPACK, sendo que essas classes oferecem métodos para manipulações matriciais básicas e para a di
