1. A QoS-Based approach for dynamic web service composition.
Web services have become a de facto standard for integration of systems in distributed environments by providing means for exchanging data in a standardized way over the Internet. In fact, this allows computer-computer interaction regardless the programming languages, platform and operating systems used. However, the way services are defined is not enough fo

2. Sins : um editor Xchart na forma de plugin para o ambiente eclipse / Sins : an Xchart editor as a plugin for the eclipse environment
: Sistemas reativos têm grande importância em muitas áreas da engenharia e da computação, mas a qualidade e maturidade das metodologias e ferramentas de apoio ao desenvolvimento deixam a desejar em relação às voltadas a sistemas transformacionais. Uma das metodologias de destaque é a Arquitetura Orientada a Modelos, onde os sistemas reativos são de

3. Um middleware para execução de processos estruturados em grades computacionais / A middleware for execution of structured processes in computer grids
O conceito de grade surgiu com a necessidade crescente de se aproveitar recursos computacionais disponíveis em uma ou mais organizações para resolver problemas que exigem compartilhamento de dados e um grande poder de processamento. Uma grade computacional tem como objetivo principal permitir a execução distribuída e paralela de tarefas em recursos com

4. COMPUTATIONAL ASPECTS OF MARKET EVALUATION OF THE DYNAMIC SECURITY ON POWER ELECTRICAL SYSTEMS / ASPECTOS COMPUTACIONAIS E DE MERCADO DA AVALIAÇÃO DA SEGURANÇA DINÂMICA DE SISTEMAS ELÉTRICOS DE POTÊNCIA
In this work, different methodologies for the dynamic security assessment of electric energy systems, the calculation of preventive control measures and the quantification of the economic impact of the generation rescheduling, are used. For the dynamic security assessment the following modules have been adopted: initial data processing and generation of the

5. Clock synchronization in computer networks with quality of service
The Network Time Protocol (NTP), a protocol that synchronizes clocks from networked computers, has nearly two decades of existence and is continuously evolving. Due to its robust treatment of phase and frequency, an algorithm that disciplines the local machine clock, implementations available for a great deal of platforms and operating systems, it became a �

6. Camada de redirecionamento : um novo paradigma para a analise de sistemas distribuidos
A multicomputer system has some characteristics which, when well explored, allow us to get real throughtput and funcionality that aren t found in other systems, or even in each individual computer. In order to explore these characteristics it is necessary to integrate, in an adequate manner, all the single resources in only one resource, now representing the

7. Improved programs for DNA and protein sequence analysis on the IBM personal computer and other standard computer systems.
We have previously described programs for a variety of types of sequence analysis (1-4). These programs have now been integrated into a single package. They are written in the standard C programming language and run on virtually any computer system with a C compiler, such as the IBM/PC and other computers running under the MS/DOS and UNIX operating systems.

8. The portable UNIX programming system (PUPS) and CANTOR: a computational environment for dynamical representation and analysis of complex neurobiological data.
Many problems in analytical biology, such as the classification of organisms, the modelling of macromolecules, or the structural analysis of metabolic or neural networks, involve complex relational data. Here, we describe a software environment, the portable UNIX programming system (PUPS), which has been developed to allow efficient computational representat
