13. Automatic knee flexion in lower limb orthoses
Lower limb orthoses are often plagued by a high rejection rate, due both to the excessive effort demanded from their users and to the lack of aesthetics of the resulting gait. These factors are caused, to a great extent, by the fact that orthoses force the whole gait to be performed with the knee articulation in full extension. This work presents a light and

14. Thermodynamic properties of the field electromagnetic field in the CPT-odd standard extended / Propriedades termodinâmicas do campo eletromagnético no setor CPT-ımpar do modelo padrão estendido
In this work we study the effects of the spontaneous breaking of Lorentz symmetry on black body radiation phenomenon in the context of the Maxwell-Caroll-Field-Jackiw (MCFJ) model. The MCFJ model is the electromagnetic CPT-odd sector of the standard model extension and, it presents for a purely space-like background a positive-definite hamiltonian. Firstly,

15. Multi-SincronizaÃÃo em menssage sequence charts
Message Sequence Charts (MSC) is a visual trace language, extensively used in academy and industry, to describe the communication behavior of system components and their environment. The MSC syntax and semantics are now a standard defined by the International Telecommunication Union (ITU). The motivation for this work has originated from an eort to model sce

16. Proposta de um modelo de confiança para o protocolo OLSR
This work presents a new computational trust model, developed to improve the packets forwarding in MANET using OLSR protocol. Mobile Ad hoc Networks (MANET) are composed of mobile devices that communicate directly without the need of any prior infrastructure. The nodes in these networks operate as routers. The Optimized Link State Routing Protocol (OLSR) is

17. Um modelo de arquitetura de matching entre perfis de usuários e serviços / A model of architecture of matching of profiles of users and services
In the era of ubiquitous computing, a new kind of application has been gaining increased attention from the academic community, the socalled Context-aware mobile applications. Context-aware computing requires context information representation mechanisms that facilitate this type of information processing within appropriate software infrastructures. One poss

18. 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

19. Estudo da consistência e soluções clássicas da eletrodinâmica de Maxwell-Carroll-Field- Jackiw-Proca / Study of the consistency and classic solutions of the electrodynamics of Maxwell-Carroll-Field- Jackiw-Proca
Neste trabalho, objetiva-se investigar signi cativos aspectos da eletrodinâmica de Maxwell-Carroll-Field-Jackiw-Proca (MCFJP). Esta eletrodinâmica é construída via a implementação de campos de fundo (backgrounds), responsáveis pela violação da invar- iância de Lorentz, no setor de gauge puro do Modelo Padrão usual. Primeiramente, averigua-se

20. Incorporação de qualidade de serviço no modelo de serviços web / Inclusion of quality of service into the web service model
Although the Web service technology allows the development and execution of distributed applications, it still lacks facilities to deal with Quality of Service (QoS). Consumers may require services with particular non-functional characteristics and expect quality level guarantees. The goal of this thesis is to propose an extended Web service architecture sup

21. Reavaliação do trem-tipo à luz das cargas reais nas rodovias brasileiras. / Re-assessment of bridge load model based on traffic data of Brazilian highways.
This work presents a model to verify the design traffic load model of the Brazilian code, based on real traffic at road bridges. First, it compares Brazilian load model with Eurocode 1 and AASHTO Standard and LRFD Specifications. Then, recent development and research on bridge traffic load models are presented, in Brazil and other countries. A verification m

22. Uma abordagem para manipulação de informações geográficas utilizando Scalable Vectors Graphics
In this work, we propose a Geographical Information System that can be used as a tool for the treatment and study of problems related with environmental and city management issues. It is based on the Scalable Vector Graphics (SVG) standard for Web development of graphics. The project uses the concept of remate and real-time mar creation by database access th

23. Identificação de sistemas "on-line", otimização e controle avançado com o filtro de Kalman estendido / On line system identification, advanced control and optimization with the (Extended) Kalman filter
In the continuing competition between it will be more and more necessary to optimize current chemical processes in real time. To be able to optimize a plant in real time, there have to be various aspects to be fulfilled, such as measurement, reliability of the measurement and prediction of the process behaviour. In this work some of the aspects of such an ad

24. Propostas de metodologias para identificação e controle inteligentes
This thesis presents proposals of methodologies for intelligent identification and control. A methodology tor nonlinear dynamic discrete time systems identification, based on the instrumental variable method and Takagi-Sugeno fuzzy model, is presented. In this methodology, which is an extension of the standard instrumental variable method, the chosen instrum
