1. Programação Genética Aplicada à Programação de Controladores Lógico Programáveis / Genetic Programming Applied to Scheduling Programmable Logic Controllers
This research proposes the application of an artificial intelligence technique called genetic programming (GP) to make easier the programming of programmable logical devices (PLC) by the automatic generation of Ladder and Instruction List programs. The system data input can be done by not-specialized people using scenarios composed by time lines. These time

2. Ambiente computacional paradesenvolvimento de aplicações de controladores lógicos programáveis baseado em linguagens SFC e ST
This work proposes an environment for programming programmable logic controllers applied to oil wells with BCP type method of artificially lifting. The environment will have an editor based in the diagram of sequential functions for programming of PLCs. This language was chosen due to the fact of being high-level and accepted by the international standard IE

3. Desenvolvimento de metodologia de aplicação de redes de Petri para automação de sistemas industriais com controladores lógicos programáveis (CLP). / Development of methodology of application of Petri Net for automation of industrial systems with programmable logic controllers.
Due to the needs of the modern world, the systems of automation have increased their complexity, forcing the development of ever more powerful engineering tolls to shape and analyse them. In systems of industrial automation, the Programmable Logic Controllers (PLCs), have been widely applies. The PLCs are generally programmed through the use of the Ladder pr

6. Integração de processos em tempo real para monitoramento e controle : aplicação para planta de PET
This work deals with the implementation of a soft-sensor for a PET (Polyethylene terephtalate) industrial process based on neural networks. The soft-sensor acts as redundant measure current for the polymer viscosity in the liquid phase; and, in case of mechanical faults, it is able to diagnoses the faults on the viscometer and can replace it.The viscosity co

7. Sistemas de automação e supervisão do laboratório de avaliação dos processos de medição de vazão e BSW
During a petroleum well production process, It is common the slmultaneous oil and water production, in proportion that can vary from 0% up to values close to 100% of water. Moreover, the production flows can vary a lot, depending on the charaeteristies of eaeh reservoir. Thus being, the meters used in field for the flow and BSW (water in the oil) measurement
