13. A middleware for service orchestration in computacional grids / GPO : um middleware para orquestração de serviços em grades computacionais
In the collaborative environment of the Computational Grids, there are few tools used for process management and user guide services. This work presents the Grid Process Orchestration (GPO), an infrastructure for service and process orchestration in computational grids, which allows to create and manage complex workflows composed of strongcoupled jobs with n

14. Proposta de implementação de uma arquitetura para a Internet de nova geração / An implementation proposal of a next generation internet architecture
A concepção original da arquitetura da Internet foi baseada em uma rede fixa e confiável. Hoje em dia, a Internet se tornou dinâmica e vulnerável aos ataques de segurança. Também não era prevista a necessidade de integração de tecnologias heterogêneas nem de ambientes sem fio. A arquitetura atual apresenta uma série de barreiras técnicas para pr

15. Aprendizagem por reforço na adaptação a obstáculos em navegação robótica autônoma não-estruturada baseada em imagens / Reinforcement learning for obstable avoidance in image based robotic autonomous non-structured navigation
In the last decades, robotic has become an important role for society, specially in the manufacturing industry. In recent times, applications of mobile robots, from simple toys to planets explorations, has shown how promising will be the use of these tools in a close future. Though, the cost and complexity in developing mobile robots nowadays, which should b

16. Layer 1 virtual private network management / Gerencia de redes virtuais privadas de camada 1
A distributed control plane architecture as GMPLS enhances transport networks with dynamic connection control. As a result, it allows the provisioning of advanced connectivity services, like Virtual Private Networks (VPNs), on layer 1 switching networks as optical and TDM networks. Such Layer 1 VPN (L1VPN) services enable multiple customer networks to share

17. 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

18. Uma arquitetura baseada em SCTP e SIP para suporte a aplicações VoIP móveis e a especificação formal do seu módulo de controle
New versions of SCTP protocol allow the implementation of handover procedures in the transport layer, as well as the supply of a partially reliable communication service. A communication architecture is proposed herein, integrating SCTP with the session initiation protocol, SIP, besides additional protocols. This architecture is intended to handle voice appl

19. Search and sharing software components in peer-to-peer networks / Busca e compartilhamento de componentes de software em redes peer-to-peer
Peer-to-peer (P2P) architectures have become a very attractive alternative to make the Internet more accessible. This approach has been widely used, from content sharing programs through communications systems, which has provided the P2P networks with considerable improvements in the technology and methodologies related. In this context, the current work pre

20. Sistema experimental de monitoramento e controle para casas de vegetação baseado em redes de controle distribuído LonWorks. / Experimental greenhouse monitoring and control system based on LonWorks distributed control network.
Protected agriculture using greenhouses allows high quality crops and in any time of the year. The technology has a preponderant role in the control of these environments, although no always successfully. Conventional solutions, such as Programmable Logic Controllers, or systems with proprietary technology are predominant. The evolution of the communication

21. Security in grid computing / Segurança em grades computacionais
Grid computing is a concept that exploits the power of computer networks, with the specific aim of making virtual layers available that allow users to have access to highly demanding applications, as well as to adhere to large scale, highly diverse, virtual communities. Grid computing provides support for the execution of parallel applications, grouping toge

23. Estudo, Análise e Proposta de Arquitetura de Integração de Sistemas Heterogêneos em Redes de Larga Escala com Adaptação de uma Plataforma de Suporte a Agentes Móveis (FT-SALE/SMAM) / Study, analysis and proposal of an architecture of integration of heterogeneous systems in nets of wide scale with adaptation of a support platform the mobile agents (FT-Sale/Smam)
A Virtual Enterprise is a temporary alliance of enterprises that come together to share skills or core competencies and resources in order to better respond to business opportunities, and whose cooperation is supported by computer networks. In this dissertation, it is presented an integration proposal of two platforms that work in the context of Virtual Ente

24. Uma nova arquitetura para a representação das regras de negócio em modelos de objetos dinâmicos / An new architecture for representing business rules in dynamic object models
The Ground System Development Division (DSS) at INPE has always developed satellite control systems with architectures that may be used as much as possible by future satellites. The present challenge is to build an Adaptive Satellite Control System, using the technology of the Dynamic Object Model, so as to comply with later requirements without having to ma
