13. Generation of a family of software products with components based architecture / Geração de famílias de produtos de software com arquitetura baseada em componentes.
Adaptation of a specific software product line process is described. The adapted process aims to be agile, minimising rework for feature design and development activities and facilitating applications engineering. The domain engineering phase is iterative and incremental, using a component-based architecture. Applications are generated by an application gene

14. MODEL-DRIVEN RESOURCE MANAGEMENT: ADAPTABILITY AND INTEROPERABILITY ON END-TO-END QOS SUPPORT / GERENCIAMENTO DE RECURSOS DIRIGIDO POR MODELOS: ADAPTABILIDADE E INTEROPERABILIDADE NO SUPORTE A QOS FIM-A-FIM
The evolution of codification techniques for continuous media is making distributed multimedia applications even more popular. This kind of application has performance requirements that must be met in an end-to-end fashion, which can be achieved only if quality-of-service (QoS) provisioning mechanisms are applied on each participant subsystem. These mechanis

15. Optimization in design parameters of mechanical systems using multi-objective genetic algorithm / Otimização de parametros de projeto de sistemas mecanicos atraves de algoritmo genetico multi-objetivos
The mechanical systems are designed to be applied to any specific situations, and in this waytheir features should be measured to guarantee confidence to the systems. Their development and analysis expose the designer to a series of unknown parameters from several sources such as material properties, environmental and operational conditions. In terms of math

16. Estimativa de consumo de energia de cÃdigo ANSI-C para sis- temas embarcados: uma abordagem baseada em simulaÃÃo estocÃstica
Embedded Systems are present in most daily activities with many different purposes. Generally, embedded systems have several design constraints, such as memory size, power source, CPU speed, and so on. Over the last years, power consumption has been receiving particular attention from scientific community since several embedded devices rely on battery as pow

17. Alocação dinâmica de recursos computacionais para experimentos científicos com replanejamento automatizado a bordo de satélites / Dybanic allocation of computational resources for scientific experiments with autonomous replanning aboards satellites
The experiments aboard the Brazilian scientific satellites are currently thought to execute its tasks in a repetitive way, collecting, storing and sending data in a cycle that does not suffer great alterations. This way of dealing with the experiments operation fits perfectly to long-term scientific observation. There are, however, short-duration scientific

18. SHDM.NET: UM FRAMEWORK E AMBIENTE DE DESENVOLVIMENTO DIRIGIDO POR ONTOLOGIAS PARA APLICAÇÕES HIPERMÍDIA / SHDM.NET: A FRAMEWORK AND DEVELOPMENT ENVIRONMENT DRIVEN BY ONTOLOGIES FOR HYPERMEDIA APPLICATIONS
This dissertation presents how a model driven development architecture and environment framework to support Web application development are being developed using SHDM/OOHDM as development methods. The models are described through graphical diagrams that are processed by the environment. The application interface is also produced using models, and the interfa

19. Estudo da radiação eletromagnetica na cabeça humana considerando efeitos quirais / Study of the electromagnetic radiation on the human head considering chiral effects
This work shows a numerical model based on the finite-difference time-domain method, with the aim of analysing the characteristics of the Specific Absorption Rate, SAR, in a human-head, through a quiral modeling of Mawell?s equations. The formulation is expressed in terms of the electric and magnetic wave-fields, allowing to investigate possible changes in S

20. INFERÊNCIAS SEMÂNTICAS NA RECUPERAÇÃO DE INFORMAÇÕES PARA APLICAÇÕES HIPERMÍDIA / SEMANTIC INFERENCES IN INFORMATION RETRIEVAL FOR HYPERMEDIA APPLICATIONS
The information overload problem is one of the most challenging problems being faced today. In order to solve this problem, different areas such as Knowledge Management, Semantic Web and Hypermedia Applications Modeling have used similar solutions that consist basically of semantically structuring the information so it can be better accessed. This dissertati

21. Treatment of geophysical data as a non-stationary process
The Kalman-Bucy method is here analized and applied to the solution of a specific filtering problem to increase the signal message/noise ratio. The method is a time domain treatment of a geophysical process classified as stochastic non-stationary. The derivation of the estimator is based on the relationship between the Kalman-Bucy and Wiener approaches for l

22. Trypanosoma cruzi interaction with the extra-cellular matrix: modeling the TC85-11 protein and mapping the laminin-binding site / Trypanosoma cruzi e a interação com a matriz extracelular: modelagem da proteína Tc85-11 e determinação do sítio de ligação a laminina
Trypanosoma cruzi expresses the Tc85 proteins, a set of surface glycoproteins belonging to the gp85/trans-sialidase supergene family. In this report we show a structure model for Tc85-11 a member of this family, which has adhesive properties to laminin and to the host cell surfaces. That structure consists in an N-terminus β-propeller and a C-terminus &

23. Um modelo de hipertexto para apoio ao ensino mediado pela Web / A hypertext model to support Web-mediated teaching
There is an increasing demand for hypermedia applications based on the WWW (World Wide Web), known as Web Information Systems (WIS). These applications present specific requirements in addition to those of traditional software systems, thus fostering the need for investigating suitable models to support their development. In particular, systems for Distance

24. Modeling and Construction of a Tool of Authorship for a Tutorial System Intelligent / Modelagem e Construção de uma ferramenta de autoria para um Sistema Tutorial Inteligente
One of the difficullties when building an Intelligent Tutoring System (ITS) is the domain model definition. This must be the result of knowledge acquisition from an experts, usually a teacher. This thesis presents the definition, modelling and implementation of an authoring tool. This tool, named authoring, provides cognitive evaluations to organize a knowle
