13. Modelagem e analise de digestores Kraft descontinuo
Global1y, the Kraft pulping process is beginning to get use of the benefits of the recent developments in the modeling area and process control. Advanced techniques of simulation and control offer tools that allow the analysis and efficient design of multivariable non-linear process, involving the optimization and the advanced control of the process. The pul

14. Analise do processo de extrusão na industria de "PET-FOOD" para a aplicação de tecnicas de controle avançado / Review of the extrusion industry in the "PET-FOOD" for the application of advanced techniques of control
The present study informs about the main features of extrusion control processes, based on product-wet density and moisture. To comprehend the study, some background of the classic control theory is provided. The process complexity, provided by formation of a bio-polymer from carbohydrate-lipid-protein raw materials, requires analysis using statistical conce

15. Identificação e controle de processos não lineares utilizando redes neurais artificiais
Considering that most of the industrial processes of interest to Chemical Engineering present a certain degree of inherent non-linearity or one introduced by systems of automatic control, an important necessity of inquiring about the performance the new techniques derived from artificial intelligence, whose interest here is in the artificial neural networks,

16. GRAPH THEORY IN OPERATIONS OF THE HYDROTHERMAL SYSTEMS / TEORIA DE GRAFOS NA OPERAÇÃO DE SISTEMAS HIDROTÉRMICOS
The search for more efficiency in the production of eletrical energy, has led several countries to re- structure their eletric sectors, traditionally under control of federal, or state governments like in England, in /spain, in New Zeland, in argentina, in Chile, in Peru (object of this work), and now in Brasil. In this new structure the profit of the privat

17. Uma contribuição ao estudo de não-linearidades na modelagem e controle de manipuladores
This work analyses the theory and simulation of Non-Linearitys found in the equations and robots control with one and two degrees of freedom. Simultaneously it is presented a detailed work on non linear system involving the development of Non Linear Controls for Industrial Manipulators. This process is moré advantageous than the classical linear controls. E

18. ARTIFICIAL NEURAL NETWORKS IN TIME SERIES FORECASTING / REDES NEURAIS ARTIFICIAIS NA PREVISÃO DE SÉRIES TEMPORAIS
This dissertation investigates the use of Artificial Neural Nerworks (ANNs) in time series forecastig, especially financial time series, which are typically noisy and with no apparent periodicity. The dissertation covers four major parts: the study of Artificial Neural Networks and time series; the desing of ANNs applied to time series forecasting; the devel

19. Dinamica e controle de colunas de destilação : aplicação a sistemas de elevada pureza
The main objective of the present study is the mathematical modelling, simulation and control of distillation columns processing high-purity overhead products. The phenomenological aspects of the dynamic behavior of columns are analysed at first to obtain a model which takes into account the main variables, beeing also flexible, reliable and practical. The n
