13. Uma Contribuicão à coordenação na computação pervasiva com aplicações na área médica / A CONTRIBUTION TO COORDINATION IN PERVASIVE COMPUTING WITH APPLICATIONS IN MEDICAL AREA
Pervasive Computing is a new paradigm that states that the computational environment must be available to the user at any time and location. In this scenario, the applications are widely distributed, mobile and hosted on inherently open and dynamic environments. Moreover, the systems must have mechanisms that enhance the cooperation among users as well as am

14. Model checking underwater vehicles control architectures: a formal specification based approach. / Checagem de arquiteturas de controle de veículos submarinos: uma abordagem baseada em especificações formais.
The development of control architectures for Underwater Vehicles is a complex task. These control architectures might be chracterised by the following attributes: real-time, multitasking, concurrency, and distributed over communication networks. In this scenario, we have multiple processes running in parallel, possibly distributed, and engaging in communicat

16. Barramento de serviÃos federados para integraÃÃo federativa de sistemas distribuÃdos / Barramento de serviÃos federados para integraÃÃo federativa de sistemas distribuÃdos Federated service bus to federative integration of distributed systems
Esta dissertaÃÃo apresenta uma proposta de middleware de comunicaÃÃo baseado em Enterprise Service Bus (ESB) para sistemas federados, isto Ã, formados por sistemas de diferentes organizaÃÃes. Este trabalho nÃo aborda o problema clÃssico de sistemas federados, cujo enfoque principal à autenticaÃÃo e a seguranÃa, mas sim uma necessidade crescente

17. A prototype implementation of a distributed satisfiability modulo theories solver in the ToolBus framework
An increasing number of verification tools (e.g., software model-checkers) require the use of Satisfiability Modulo Theories (SMT) solvers to implement the back-ends for the automatic analysis of specifications and properties. The most prominent approach to build SMT solvers consists in integrating an efficient Boolean solver with decision procedures capable

18. RUP extension for development of distributed systems.
The increasing number of distributed systems results from the progress of computing and communication technology. This progress contributed to the expansion of Internet, increasing both availability and decentralization of the storage and processing. Nowadays the development of mature software for those systems is accomplished through the use of good practic

19. Uma arquitetura distribuída de hardware e software para controle de um robô móvel autônomo
In this work, we present a hardware-software architecture for controlling the autonomous mobile robot Kapeck. The hardware of the robot is composed of a set of sensors and actuators organized in a CAN bus. Two embedded computers and eigth microcontroller based boards are used in the system. One of the computers hosts the vision system, due to the signiᤙ

20. Um modelo de arquitetura de matching entre perfis de usuários e serviços / A model of architecture of matching of profiles of users and services
In the era of ubiquitous computing, a new kind of application has been gaining increased attention from the academic community, the socalled Context-aware mobile applications. Context-aware computing requires context information representation mechanisms that facilitate this type of information processing within appropriate software infrastructures. One poss

21. A methodology for development augmented reality applications using mobile phones and sensors devices. / Uma metodologia para o desenvolvimento de aplicações de realidade aumentada em telefones celulares utilizando dispositivos sensores.
Handheld Augmented Reality or Handheld AR is the implementation of Augmented Reality (AR) systems into handheld devices. Handheld AR applications use the handheld devices camera to recognize markers (inserted into the environment). This process enables data entry into AR system. The response generated for these applications are presented as virtual images (3

22. âA Context-based Name Resolution Approach for Semantic Schema Integrationâ
The Semantic Web envisages providing a broad range of services from various application domains on the Web. These services often work in a collaborative way and are based on decision-making tasks, which are performed better if they are able to take into account all the relevant information available. This scenario has given rise to technical developments in

23. Celine: um modelo para utilização e adaptação de conteúdo scorm em ambientes inteligentes de aprendizagem
The effort to maintain contents in ILE (Intelligent Learning Environments) was the inspiration behind the development of this work. It was observed that the contents to be taught are heavily reliant on these environments, which makes their sharing with other systems difficult. In addition, these materials are created with internal tools, which offer few reso

24. Control algorithms for an autonomous mobile robot for soda can collection. / Controle de robô móvel autônomo para coletar lixo.
This work presents the control system for an autonomous mobile robot for soda can collection. The navigation system is implemented using a reactive architecture called "Motor-Schema". This architecture provides a methodology to design primitive behaviors that can act in a distributed and parallel manner to yield intelligent robotic actions in response to env
