13. VXDL: A LANGUAGE FOR INTERCONNECTION AND RESOURCES SPECIFICATION IN VIRTUAL GRIDS / VXDL: UMA LINGUAGEM PARA DESCRIÇÃO DE INTERCONEXÕES E RECURSOS EM GRADES VIRTUAIS
Grid computing has been defined as an infrastructure integrator of distributed resources. Although it is already used on a large scale in many areas, this type of computational infrastructure is still an area of active research, with many open questions. Today, new research works investigate the application of resources virtualization techniques to perform t

14. Ajax : an adaptive join algorithm for extreme restrictions
Resumo: Uma Comunidade de Bancos de Dados Móveis (MDBC) representa uma coleção de bancos de dados móveis e autônomos. Em tal contexto, cada usuário de um sistema de banco de dados participante da comunidade pode acessar os outros bancos de dados através de uma infra-estrutura de comunicação sem fio. A utilização de técnicas tradicionais para proc

15. Application of mathematical analysis in IP number backtracking to use in TCP/IP networks under denial-of-servicfe attack. / AplicaÃÃo da anÃlise matemÃtica no rastreamento reverso do nÃmero IP para o uso em redes TCP/IP sob ataque de negaÃÃo-de-serviÃo
The denial-of-service attack was unveiled in the year of 1988 and became a serious threat to the computer networks to carry on properly, around the world. When this kind of attack is going on the victim suffers so high increment in demanding computational resources, that they may become unavailable to the true users. Despite the fact that there exist other k

16. MODELOS E ALGORITMOS PARA ANÁLISE DE CONGESTIONAMENTO E DETERMINAÇÃO DE PARADAS NA LOGÍSTICA FERROVIÁRIA / MODELS AND ALGORITHMS FOR CONGESTION ANALYSIS AND YARD USE DETERMINATION IN RAILWAY LOGISTICS
Planning in Railway Logistic is an activity with growing importance. This is due to the high costs of investment to increase the railway capacity. Nevertheless, planning in this context is a cumbersome task, since a precise representation is necessary to consider most relevant points in this activity. Mathematical programming is becoming one of the best ways

17. Uncertainty-based key agreement protocol.
This work introduces a new encryption algorithm. The main motivation to the suggested algorithm is to attempt to open new ways and alternative visions that may be eventually integrated into well established cryptography algorithms being used today. When RSA, DES, and several other algorithms are compared, at least a common and central point can be identified

18. A system for active analysis of firewall behavior. / Um sistema para análise ativa de comportamento de firewall.
Due to the importance of the firewalls for protection of network computers, a lot of studies has been done in order of the improvement of the protection techniques and in the development of new techniques to be used in the analysis of them. With focus in this theme, this thesis considers the viability of the technique of injection of packages and observation

19. Instrumentação inteligente via web services. / Intelligent instrumentation through web services.
In this work is presented the integration of an established system of intelligent instrumentation with the Web Service?s architecture, in accordance with the IEEE 1451.1 standard. It is suggested the association of a data-communication protocol with the concept of Transducer Electronic Data Sheet (TEDS) to a Web Service for making possible the remote configu

20. Estudo sobre a variação dos parâmetros do Tree Load Balancing Algorithm / Study about the variation of the Tree Load Balancing Algorithm parameters
In locally distributed systems, when plenty of tasks are randomically submitted to network computers where certain computers may be heavily loaded, while others lightly loaded, load balancing algorithms may be used on to homogenize and optimize the resources allocation, and hence improve the computer performance. Later on, the distributed systems evolution m

22. Storage networks architectures / Arquiteturas de redes de armazenamento de dados
Storage Networks offer shared access to data storage devices, increasing the efficiency and the availability of storage data. They allow data storage devices, from different suppliers, using different access protocols, to be logically available for access. They also allow management of data, backup and recovery, data replication, disaster recovery environmen

23. Gereciamento SNMP com autenticaÃÃo remota: aplicaÃÃo em UPSs / Management SNMP with remote authentication:applications in UPSs
The reliability of a computer system is based not only on the computer itself, but also on its related power system. For that reason, more and more critical systems are counting on UPSs (Uninterruptible Power Supplies) to account for a continuous supply of power. Although the task of managing an UPS for a standalone system be quite straightforward, when it c

24. "Computational simulations biologically plausible of neurons of the primary somatosensory cortex" / "Simulações computacionais biologicamente plausíveis de neurônios do córtex somestésico primário"
Since its appearance, the computer has been used to model phenomena in all areas of knowledge. In neuroscience, computer modeling is used to describe, reproduce and predict behaviors of different components of the nervous system. As well as in other areas of sciences, this procedure has been shown to be efficient in the study and improvement of theories on b
