3. Gerenciamento de anotações semanticas de dados na Web para aplicações agricolas / Management of semantic annotations of data on the Web for agricultural applications
Geographic information systems (GIS) are increasingly using geospatial data from the Web to produce geographic information. One big challenge is to find the relevant data, which often is based on keywords or even file names. However, these approaches lack semantics. Thus, it is necessary to provide mechanisms to prepare data to help retrieval of semantically

4. TEMPORAL SYNCHRONISM CONTROL OF HYPERMEDIA APPLICATIONS / CONTROLE DO SINCRONISMO TEMPORAL DE APLICAÇÕES HIPERMÍDIA
Synchronization control in hypermedia applications is one of the most important requirements in the presentation of these applications. To assure highquality presentations, it is necessary to know when events, produced during an application execution, occur in time. By means of this information, it is possible to predict undesirable delays and to forestall a

5. AlocaÃÃo de recursos com justiÃa: uma aplicaÃÃo de jogos cooperativos em redes de computadores
This work presents a methology for applying cooperative game theory concepts for solving the bandwidth allocation problem within differentiated traffic profiles for Internet applications. The multi-service networks scenario is explored as an operational network example for fair bandwidth sharing mechanisms. This operational network uses mechanisms based on s

6. Proposed Threshold-Based Connection Admission Control (CAC) Algorithm for IEEE 802.16 Networks / Proposta de algoritmo de controle de admissão de conexões baseado em Threshold para as Redes IEEE 802.16
IEEE 802.16 standard, also called WiMAX (Worldwide Interoperability for Microwave Access), is one of the most promising technologies for BWA (Broadband Wireless Access) networks. The IEEE 802.16 standard provides specification of MAC and physical layer. The standard adds to the BWA networks some advantages over other technologies, such as wide area of covera

7. Segurança para o sistema brasileiro de televisão digital: contribuições à proteção de direitos autorais e à autenticação de aplicativos. / Security on brazilian digital television system: contributions to the digital rights protection and to applications authentication.
In Brazil, the television system is considered an important source of communication and entertainment. The Brazilian digital transmissions started on December 2007 and first offered functionalities were the high definition, mobility and portability. In a later moment other functionalities will be added: multiprogramming (more than one service per channel) an

9. 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
