1. Fuzzy control applied to an electrical power generation system mounted on tractors for driving of agricultural implements
ABSTRACT The demand of the agricultural sector for more operationally efficient machines and implements motivated the development of alternatives for driving of this equipment. Aiming an electrical supply to apply in agricultural implements, this study proposes a system that uses the tractor power take off to activate a synchronous generator, using a fuzzy l

2. A timestamp-based two phase commit protocol for web services
Service Oriented Architecture (SOA) allows the development of software with requirements of interoperability and loose coupling. New services can be offered through the composition of existing services in order to address new business requirements. Business-to-business collaborative web applications demand a loosely coupled, coarse-grained interaction model.

3. Proposta de um procedimento para a modelagem de sistemas de controle de edifícios inteligentes utilizando a rede de Petri colorida. / A procedure for modelling the control system in intelligent buildings based on colored Petri nets.
Technological advances in recent decades have motivated the development of intelligent buildings, aimed at creating environments more productive for the occupants, economically advantageous for the owners and environmentally correct. New ways of interaction between users and the buildings systems are emerging from these kinds of systems, which are not adequa

4. EFEITO DOS ESPECTROS DE GOTA ASSOCIADOS A DIFERENTES ARQUITETURAS DE CULTIVARES DE SOJA NO CONTROLE DA FERRUGEM. / EFFECT OF DROP SPECTRA ASSOCIATED WITH DIFFERENT ARCHITECTURES OF SOYBEAN CULTIVARS IN CONTROL OF THE RUST.
A eficiência de um fungicida é o resultado da associação de uma série de fatores como: momento da aplicação, condições ambientais, condição fisiológica da planta e tecnologia de aplicação utilizada. Já para esta última a adequada deposição e distribuição do ingrediente ativo no alvo é determinante para eficiência do processo. O objetivo

5. SCAE: uma abordagem baseada em agentes inteligentes para gerenciamento e controle de campos de petróleo / SCAE: an approach based on intelligent agents for management and control of oil fields / SCAE: uma abordagem baseada em agentes inteligentes para gerenciamento e controle de campos de petróleo / SCAE: an approach based on intelligent agents for management and control of oil fields
Several existing systems, whether in nature, whether in companies human exhibit the characteristic of being formed by individuals or subsystems that cooperate to carry out their tasks, and thus achieve a global goal. Examples these systems range from a society of bees to an organization financial, community animal to a manufacturing system, among many others

6. Heuristic solutions related to challenges of optical burst switching paradigm
Several optical network switching paradigms have been under intensive research to support rapidly increasing bandwidth requirements. Of all these paradigms, optical burst switching (OBS) is a promising switching paradigm for the next-generation Internet infrastructure. Despite the significant contributions of OBS to high speed networks such as dynamic connec

8. Um modelo de memória transacional para arquiteturas heterogêneas baseado em software Cache / A transactional memory model for heterogeneous architectures based in Software Cache
The adoption of multi-core processors by the industry has pushed towards the development of new techniques to simplify programming parallel software. The technique called transactional memories is one of the most promising. This technique is able to execute multiple tasks concurrently in an optimistic way to achieve a better performance. Another advantage is

9. Uma arquitetura de controle de qualidade de serviço aplicada a redes heterogêneas e serviços convergentes. / An architecture for QoS control applied to heterogeneous networks and convergent services.
One of the targets of the next generation communication systems is to provide access to any service, to any user, anytime, anywhere, regardless the access network technology or type of user device (mobile phone, PDA, personal computer, and so on). This scenario is called convergence of services by heterogeneous networks, and in such scenario quality of servi

10. Arquitetura modular de processador multicore, flexível, segura e tolerante a falhas, para sistemas embarcados ciberfísicos. / Modular multicore processor architecture, flexible, securi and fault tolerant, to embedded cyber-physical systems.
Cyber-physical Systems (CPS) are systems where there is an union between computing and physics. The CPS will be used in several areas, forming a new era of systems or devices and could be anywhere, being used by anyone and anything. Applications for CPS include highly reliable medical systems and devices, traffic control and security, advanced automotive, pr

11. Validation of consumers in services oriented architecture (SOA): a framework to validate legitimacy of service consumers and their access means. / Atestamento em arquitetura aberta de serviços (SOA): um arcabouço para validação de legitimidade dos consumidores de serviços e seus dispositivos de acesso.
In Service Oriented Architectures (SOA) the concern with security has received important focus on solution design as a consequence of intrinsic vulnerabilities at the basis of this new paradigm. This work proposes a framework to secure development of SOA applications, with a special attention to security matters regarding validation of service consumers and

12. 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
