1. Teste de robustez de uma infraestrutura confiável para arquiteturas baseadas em serviços Web / Robustness testing of a reliable infrastructure for web service-based architectures
Os sistemas baseados em serviços Web estão suscetíveis a diversos tipos de falhas, entre elas, as causadas pelo ambiente em que operam, a Internet, que está sujeita a sofrer com problemas como, atrasos de entrega de mensagem, queda de conexão, mensagens inválidas entre outros. Para que estas falhas não causem um problema maior para quem está interagi

2. Arquitetura modular de processador multicore, flexível, segura e tolerante a falhas, para sistemas embarcados ciberfísicos. / Modular multicore processor architecture, flexible, securi and fault tolerant, to embedded cyber-physical systems.
Cyber-physical Systems (CPS) are systems where there is an union between computing and physics. The CPS will be used in several areas, forming a new era of systems or devices and could be anywhere, being used by anyone and anything. Applications for CPS include highly reliable medical systems and devices, traffic control and security, advanced automotive, pr

3. Uma abordagem arquitetural para o desenvolvimento rigoroso de sistemas confiáveis baseados em componentes / A rigorous architectural approach to development component-based software systems
The incorporation of fault tolerance into systems normally increases their complexity, which consequently makes their analysis more difficult. Moreover, the use of exception handling mechanisms to develop robust software systems in a non-systematic manner can be a source of many design faults. This thesis presents a rigorous and architecture-centric developm

4. Proposal of two solutions to cope with the faulty behavior of circuits in future technologies
A diminuição no tamanho dos dispositivos nas tecnologias do futuro traz consigo um grande aumento na taxa de erros dos circuitos, na lógica combinacional e seqüencial. Apesar de algumas potenciais soluções começarem a ser investigadas pela comunidade, a busca por circuitos tolerantes a erros induzidos por radiação, sem penalidades no desempenho, ár

5. Um modelo hÃbrido e adaptativo para sistemas distribuÃdos tolerantes a falhas
A distributed system can be defined as a set of processes that communicate via communication channels. Models for such systems characterize its aspects, mainly in the temporal and reliability domains. Partially synchronous models have been successfully developed to circumvent the impossibility of achieving fault tolerant consensus in pure, time free, asynchr

6. PROCESS CONTROL SYSTEMS : DEPENDABILITY AND PERFORMANCE MODELING
Today, a wide variety of computer systems are required to react automatically to various events generated by external processes and/or human operators. An important class of these process control systems, called hard real-time systems, need to respond to events under severe timing constraints expressed in terms of deadlines and earliest starting times. In ge

7. SOFTWARE ARCHITECTURES FOR FAULT-TOLERANT REPLICATIONS AND MULTITHREADED DECOMPOSITIONS : EXPERIMENTS WITH PRACTICAL PARALLEL SIMULATION
This thesis is concerned with the experimental development of parallel simulation tools that not only exploit diverse multiprocessor environments, but also allow parallel simulations to be built with reasonable effort. We work on two fronts: model replication and model decomposition. We describe the design of EcliPSe, a parallel simulation system for replica
