1. Uma abordagem complementar à tradução de endereços para conectividade transparente
Traditional NAT is an extremely common technique, employed on routers in order to share on single Internet connection among many computers of a local network. This technique has been responsible for the survival of IPv4 with its limited address space, and is virtually transparent to many of the Internet application: those that uses the classic client-server

2. Integrating mixed-reality remote experiments into virtual learning environments using interchangeable components
This paper presents a proposal to integrate mixedreality remote experiments into virtual learning environments (VLEs) using the concept of interchangeable components, which can represent either real or virtual devices or software in industrial automation systems. Combinations of real and virtual technical plants and automation systems are used in different l

3. Análise de desempenho de plataformas de educação a distância com arquitetura cliente-servidor utilizando teoria de filas / Performance analysis of a distance education platform with client-server architecture using queuing theory
Neste trabalho, propõe-se um modelo de análise para prever o desempenho de um sistema cliente-servidor referente a uma plataforma de Educação a Distância. Esta abordagem é baseada na teoria de filas e pode descrever adequadamente o desempenho de uma plataforma de Educação a Distância e seus parâmetros, como por exemplo, o tempo médio de resposta d

4. Environnement d'exécution parallèle : conception et architecture
L'objectif de cette thèse est l'étude d'un environnement d'exécution pour machines parallèles sans mémoire commune. Elle comprend la définition d'un modèle de programme parallèle, basé sur l'échange de message offrant une forme restreinte de mémoire partagée. La communication est indirecte, via des portes; les processus utilisent les barrières p

6. A progressive vector map browser for the web
With the increasing popularity of web-based map browsers, remotely obtaining a high quality depiction of cartographic information has become commonplace. Most web mapping systems, however, rely on high-capacity servers transmitting pre-rendered tiled maps in raster format. That approach is capable of producing good quality renderings on the client side while

7. Reconfigurable hardware platform for research and distance learning on remote laboratories for digital systems / Plataforma em hardware reconfiguravel para o ensino e pesquisa em laboratorio de sistemas digitais a distancia
This thesis presents a reconfigurable hardware platform called REDLART (REconfigurable Digital Laboratory for Advanced Research and Teaching), designed to enable laboratory applications in distance learning and collaborative work in digital systems. The platform is based on FPGA devices (Field Programmable Gate Array) to develop digital circuit applications

8. CONTEXT-BASED CONTENT ADAPTATION FOR PUBLISH/SUBSCRIBE SYSTEMS / SUPORTE À ADAPTAÇÃO DE CONTEÚDO SENSÍVEL A CONTEXTO PARA DISPOSITIVOS MÓVEIS EM SISTEMAS PUBLISH/SUBSCRIBE
Services for information dissemination (push services) are being widely used, in particular for applications involving mobile users. These services generally serve devices with diferent resources and with distinct execution contexts (wireless connectivity, energy source, etc.), making it necessary to adapt disseminated content individual and dynamically for

9. CONCURRENCY AND SANDBOXES MODELS APPLIED TO LUA HTTP SERVERS / MODELOS DE CONCORRÊNCIA E SANDBOXES APLICADOS A SERVIDORES HTTP EM LUA
Client-server developers constantly have to deal with questions concerning performance and scalability, since the number of simultaneous clients can grow significantly. Moreover, if these systems can execute third-party code, there is also the concern of secure execution of these pieces of code. This work goal is to benchmark several combinations of concurre

10. Desenvolvimento de um WebLab para experimentos remotos em fotônica integrado a um ambiente virtual de ensino-aprendizagem
The association of Web Technology with instrument automation and control by computer has made possible the development of the so called Remote Laboratories or WebLabs distributed environments that allow to access and control experiments remotely through the Internet. In this work, a WebLab was developed for the remote measurement of the attenuation coefficie

11. SimRP - simulador de redes de petri flexível com geração de código VHDL
The objective of this dissertation is to implement a description and simulation CAD tool for Petri Nets (PNs) based on open source, called SimRP. This CAD tool will be able to describe and simulate several PNs namely Ordinary, Temporal, Temporized and Interpreted types. Besides this, SimRP provides an option to generate VHDL code (a hardware description lang

12. A SERVICE FOR MATCHMAKING OF LOCATION-DEPENDENT INTERESTS / UM SERVIÇO DE MATCHMAKING DE INTERESSES DEPENDENTES DE LOCALIZAÇÃO
This work presents a matchmaking service (MMS) to enable meetings among co-localized people sharing similar interests. To make possible meetings and collaborations, the MMS analyses profiles of co- localized users using mobile devices, and indicates which users have a high degree of similarity among their profiles. The profiles are described using ontologies
