1. PARALLEL TOPOLOGICAL SUPPORT FOR FINITE ELEMENT MESHES IN DYNAMIC FRACTURE AND FRAGMENTATION ANALYSES / SUPORTE TOPOLÓGICO EM PARALELO PARA MALHAS DE ELEMENTOS FINITOS EM ANÁLISES DINÂMICAS DE FRATURA E FRAGMENTAÇÃO
Fracture propagation and fragmentation phenomena in solids can be described by Cohesive Zone Models and simulated with the Finite Element Method. Among the computational approaches of recent interest for fracture representation in finite element meshes are those based on cohesive elements. In those approaches, fracture behavior is represented by cohesive ele

2. 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

3. M3DS: a dynamic model of distributed development of software. / M3DS: um modelo de dinâmica de desenvolvimento distribuído de software.
This work presents a dynamic model of distributed development of software, whose objective is to represent the reality and the aspects of DDS environments, in order to turn them qualitatively and quantitatively observable. A preliminary model was elaborated from the bibliographical revision and an experimentation case developed by LErario et al (2004). The c

4. Using semantics to enhance query reformulation in dynamic distributed environments
Query answering has been addressed as a key issue in dynamic distributed environments. An important step in this process is reformulating a query posed at a peer into a new query expressed in terms of a target peer, considering existing correspondences between them. Traditional approaches usually aim at reformulating queries by means of equivalence correspon

5. 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

6. A contribuição de zonas antropogênicas na dinâmica de uso e consumo de recursos vegetais na caatinga
Anthropogenic areas constitute an important source for plants obtainment in tropical regions, cause in them several plants are found for different purposes, such as medicinal, food and wood. The aim of this work is identify the role of the anthropogenic areas in the dynamic of use of vegetable resources, as well as assess the recognition of the found species

7. Ecologia e modelagem da distribuição dos sítios de nidificação do jacaré-açu (Melanosuchus niger) em uma área de várzea da Amazônia Central, Brasil
The black caiman, Melanosuchus niger, is primarily an Amazonian species, its largest populations are associated mainly with interior várzea areas, but its nesting ecology related with these hydrologic dynamic environments is still poorly understood. The objectives of this study were related to the generation of information on the nesting ecology of this spe

8. ANÁLISE ESPACIAL DOS FRAGMENTOS FLORESTAIS NA ÁREA DO PARQUE NACIONAL DOS CAMPOS GERAIS, PARANÁ
The fragmentation of habitats figures into the most serious threats to the conservation of ecosystems nowadays. As a direct result of the human action, the fragmentation of the natural environment produces different environments that modify the dynamic of ecological relations among fauna, flora and the abiotic system. The rupture of a landscape unit generate

9. 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

10. Serviços de transação abertos para ambientes dinamicos / Open transaction services for dynamic environments
Tecnicas de processamento de transações tem sido de grande importancia no que diz respeito a preservação da correção em diversas areas da computação. Devido a funções como, garantir a consistencia de dados, a recuperação de falhas e o controle de concorrencia, transações são consideradas blocos de construção apropriados para a estruturação

11. UM ARCABOUCO PARA APLICAÇÕES DE ACESSO A SERVIÇOS DE MONITORAMENTO MULTI-DOMÍNIO / A FRAMEWORK FOR ACCESS APPLICATIONS TO MULTI-DOMAIN MONITORING SERVICES
Network performance measurements that cross different administrative domains are difficult to be obtained, due to use policy issues, security, etc. For these reasons, some national networks started efforts to allow the access to these types of measures, among them the Internet2, Géant2 and RNP. Given these efforts, it was created a document that defined and

12. Adapta: um arcabouço para o desenvolvimento de aplicações distribuídas adaptativas / Adapt: a framework for the development of applications Distributed adaptive
Modern computing environments are characterized by a high degree of dynamism that, along with the heterogeneity of computational devices and communication infrastructure, demand the development of a new range of applications that must be able to self-adapt dynamically and transparently according to changes in its execution environment. A computational grid i
