14. NavCon : uma arquitetura para navegação conceitual em ambientes de gestão do conhecimento / NavCon: Uma Arquitetura para Navegação Conceitual em Ambientes de Gestão do Conhecimento
Intranets provide access to corporate information, systems and tools for cooperative work. In corporate environments, intranets have been important resource for knowledge management. Intranets are heavily Web-based environments, where the demand for an item is generally performed by a search engine followed by manual navigation. Most users have difficulty in

16. Biologia e sucesso reprodutivo de mimus saturninus (aves: mimidae) no cerrado
The Chalk-browed Mockingbird, Mimus saturninus (Mimidae) is a very common bird in cerrados, grasslands, and pasturelands with scattered trees or shrubs, also occurring in urban environments. Here I studied aspects of its breeding biology and success in a natural cerrado. Data was collected at Estação Ecológica de Águas Emendadas (ESECAE) from 2003 to 200

17. Cooperative object manipulation in collaborative virtual environments
Cooperative manipulation refers to the simultaneous manipulation of a virtual object by multiple users in an immersive virtual environment (VE). In this work, we present techniques for cooperative manipulation based on existing single-user techniques. We discuss methods of combining simultaneous user actions, based on the separation of degrees of freedom bet

18. Ambientes de comunicação alternativos com base na realidade aumentada para crianças com paralisia cerebral: uma proposta de currículo em ação
Children with cerebral palsy may be unable to perform oral or written communication and manipulate traditional computer data input devices (mouse and keyboard) due to motor problems. People with special needs must have an alternative environment with a simple autonomous interface. Augmented Reality environments can offer interactivity and multimedia informat

19. MODEL-DRIVEN RESOURCE MANAGEMENT: ADAPTABILITY AND INTEROPERABILITY ON END-TO-END QOS SUPPORT / GERENCIAMENTO DE RECURSOS DIRIGIDO POR MODELOS: ADAPTABILIDADE E INTEROPERABILIDADE NO SUPORTE A QOS FIM-A-FIM
The evolution of codification techniques for continuous media is making distributed multimedia applications even more popular. This kind of application has performance requirements that must be met in an end-to-end fashion, which can be achieved only if quality-of-service (QoS) provisioning mechanisms are applied on each participant subsystem. These mechanis

20. Aspectos do cuidado cooperativo em dois grupos de Callithrix jacchus selvagens
The Callitrichidae family presents cooperative breeding, where breeders and non breeders take care of the offspring. The aspects of care analyzed in this study were infant carrying, supervision, proximity and food transfer. Three sets of infants from two wild groups of Callithrix jacchus were studied in the environments of Caatinga (Assu group) and Atlantic

22. Separating crosscutting concerns in agent oriented detailed design: the social patterns case
Although agent-oriented software engineering is quite recent, this new paradigm has been successfully used in industrial applications, such as telecommunications and e-commerce. Among the several issues required for the consolidation of this new paradigm, we highlight the need for suitable methodologies, notations and tools to support agentoriented software

23. Alloying in GeSi:Si (001) epitaxial nanocrystals / Formação de ligas em nanocristais epitaxiais de GeSi:Si (001)
The structural and electronic properties of nanoscale materials strongly depend on the chemical composition, as well as their size and shape. A big variety of morphologies can be achieved by controlling the experimental conditions during the epitaxial growth of Ge on a Si(001) substrate. In particular, three-dimensional islands with well defined size and sha

24. ALGORITMOS GENÉTICOS NA FORMAÇÃO DE GRUPOS PARA APRENDIZAGEM COOPERATIVA APOIADA POR COMPUTADOR / GENETIC ALGORITHMS IN THE FORMATION OF GROUPS STOP COOPERATIVE LEARNING SUPPORTED BY COMPUTER
This work presents a boarding based on genetic algorithms for the resolution of the groups formation problem for the computer supported cooperative learning. In this boarding the problem is defined as a optimization task in which if it intends to optimize the quality of the groups formed for the application of the cooperative model of teach-learning used in
