FAB LABs: Estímulo à Inovação, Usando a Fabricação Digital

FAB LABs: Estímulo à Inovação, Usando a Fabricação Digital: The analyzis of several collaborative manufacture spaces – Maker Spaces – like Fab Labs, Hackerspaces, and Techshops, and its social and economic impact in the environments where they are inserted will be fulfilled. The advantages of these spaces in the insertion of individuals in the world of technique, without discrimination of gender, qualifications, training, race or religion will also be analyzed. The insertion of women in these spaces, and the training of adults and youngsters who did not follow studies at the university will be highlighted. The goal of this work is to study the creation of collaborative spaces for innovation in the exploration of the creative capacities of their communities, focused on spaces of digital manufacturing like Fab Labs. The results leading to innovation created in these spaces, as well as its various stakeholders will be described. Collaborative learning and building a community enhance the sharing of experience and knowledge that leverage the creation of new inventions with innovation potential. The utilization of digital manufacturing technologies, available in these spaces, together with the knowledge available and shared in the network where they belong, make possible to quickly verify the acceptance of the solutions conceived and measure the public interest as well as its critiques and suggestions of improvement. Some examples of advantages and solutions promoted by these spaces will be presented. In only one year, Ford Motors impro...

Federated Persistent Data Repository Approach for FIBRE multi-CMF Testbed

Federated Persistent Data Repository Approach for FIBRE multi-CMF Testbed: A Network for Experimentation (NfExp) is typically a regional, national, or specialized international testbed like GENI, PlanetLab, and OFELIA that are developed to support the experimentation of new protocols, services and applications mostly in the context of Future Internet (FI). In effect, a Network for Experimentation allows an experimenter to configure, instantiate, run, and collect measurements of distributed experiments on top of a real testbed managed by a Control and Monitoring Framework (CMF). Currently available CMFs developments are directly or indirectly service-oriented architectures focused, as an example, on wired or wireless networks research domains. A new approach for the Network for Experimentation considered in this paper is the FIBRE multi-CMF testbed. In FIBRE, various existing CMFs are integrated to achieve a broader set of supported applications and service domains. Among the technical challenges involved in the multi-CMF approach, this paper describes the approach adopted for the persistent data repository necessary to store the monitored and collected experimental data.  An iRODS-based federated monitoring persistent data repository proposal is presented for the FIBRE multi-CMF testbed. The solution adopts a standardized monitoring data format and representation whenever possible. It is a transparent data storage facility among multiple native DBMS, with persistent monitoring data access and retrieval, and a high-level monitoring data integration.

Network Self-Management Pseudo-Predictability based on Case-Based Reasoning

Network Self-Management Pseudo-Predictability based on Case-Based Reasoning: Network self-management, among other objectives, looks for solutions (systems, frameworks and/or strategies) in which the human intervention is drastically reduced in the analysis and planning of new network states, which in turn, is based on a set of SLAs (Service Level Agreement) definitions and traffic profile. The self-management system/framework has to find a solution meeting SLA and traffic requirements within a reasonable computational time (execution time) in order to achieve a near real time operation. In general, it is necessary to adopt approaches based on reasoning and learning in self-management systems in order to avoid and/or reduce human intervention [1]. As such, self-management systems/frameworks do require the storage of network states. In this context, it is important to identify critical states and, if possible, to predict when they will occur in order to facilitate the self-management process. In this paper, a proposal for pseudo-predictability based on Case-Based Reasoning (CBR) is presented. The pseudo-predictability CBR method considers previous network states to infer future network state scenario. It was developed for the self-management framework defined in [2] and, in general, further promotes the scalability of self-managed systems.

Avaliação de Protocolos Multicast

Avaliação de Protocolos Multicast: With the development of new computer network applications based on TCP/IP protocols we need to improve the performance of these protocols to match the new application demands. In order to provide these enhancements, research and developments on TCP/IP is under way for new mechanisms to reduce the use of bandwidth as much as possible. Accordingly, a new concept called multicast traffic has been developed to transmit data from one location to many others. This paper evaluates some multicast protocols that are being developed currently with respect to the routing mechanism focusing on the average delay time, the behavior of the routing tables, the use and overloading of the links. This allows to choose the most adequate protocol given the requirements of each topology of the network and the resources available.

Uma Proposta de Arquitetura de Suporte para a Qualidade de Serviço Orientada para Aplicações de Telemedicina

Uma Proposta de Arquitetura de Suporte para a Qualidade de Serviço Orientada para Aplicações de Telemedicina: Essa dissertação propõe e avalia uma arquitetura de suporte de Qualidade de Serviço para aplicações de Telemedicina, com suporte ao uso concorrente de Vídeo sob Demanda e Videoconferência sobre uma infraestrutura de rede IP. A arquitetura de Qualidade de Serviço (QoS - Quality of Service) considerada é o DiffServ (Differentiated Services) proposta pelo IETF (Internet Engineering Task Force). Em particular, este estudo propõe a utilização de um elemento gerenciador de políticas de QoS – o Bandwidth Broker – que recebe solicitações de alocação dinâmica de recursos das aplicações de Vídeo sob Demanda e Videoconferência, valida as solicitações contra contratos de níveis de serviço (SLAs - Service Level Agreements) acordados, e aloca recursos através de distribuição de configuração de mecanismos DiffServ em dispositivos de roteamento na rede. Esse trabalho especifica uma solução de integração da rede de vídeo digital a um elemento gerenciador de políticas ao nível de plano de controle – o Bandwidth Broker, de forma a permitir o gerenciamento dinâmico de recursos baseado em políticas. Especifica e prototipa, ainda, uma infraestrutura de suporte para configurações, fazendo uso de plataformas Linux, e valida resultados de implementação de mecanismos de Qualidade de Serviço DiffServ. Para este fim são considerados...
