13. Mathematical Modeling and Numeriacal Methods for Simulation of the Heat Conduction in Liquid Helium / Modelagem Matemática e Métodos Numéricos para Simulação da Condução do Calor no Hélio Líquido
The element helium, found mainly in natural gas reserves, condenses at temperature of 4.2K, and is the unique known substance that remains in liquid to absolute zero. In the liquid phase, the helium presents still another phase change in 2.19K, where passes of common liquid to superfluous liquid, with almost zero viscosity. These properties give the helium i

14. Considerações sobre o desenvolvimento de linguagens adaptativas de programação. / Considerations about the development of adaptive programming languages.
Adaptive devices comprehend a subjacent (usually non-adaptive) device, e.g. an automaton, a grammar, etc., to which an adaptive mechanism is added which performs the self-modification operations usual in adaptive devices. Adaptive languages are special adaptive devices whose subjacent formalism is a programming language. This work defines adaptive programmin

15. Grapheme-phoneme translation for portuguese based on adaptive automata. / Tradução grafema-fonema para a língua portuguesa baseada em autômatos adaptativos.
This work presents a study on the use of adaptive devices for text-to-speech translation. The work focuses on the development of a grapheme-phoneme translation method for Portuguese based on Adaptive Automata and the use of this method in a text-to-speech translation software. The presented method resembles human behavior when handling syllable separation ru

16. Proposta de um gerador de ambientes para a modelagem de aplicações usando tecnologia adaptativa. / A proposal for an environment generator for modeling application using adaptive technology.
This research aims at proposing an environment generator (meta-environment) which makes it possible the automatic environment generation for the project of adaptive applications. This generator establishes its concepts in Adaptive Technology and allows the definition of rule-driven adaptive devices. When developing the present study, we considered the genera

17. Objetos adaptativos: aplicação da tecnologia adaptativa à orientação a objetos. / Adaptive objects: application technology to the object-oriented.
This study addresses the issue of implementing object-oriented software with adaptive characteristics, having as primary purpose simplify the implementing process. The key theoretical basis consisted in adaptive technology and its application in various formalisms. Adaptive Object Model has been taken as comparison basis to solutions to implement adaptive sy

18. Adapta: um arcabouço para o desenvolvimento de aplicações distribuídas adaptativas / Adapt: a framework for the development of applications Distributed adaptive
Modern computing environments are characterized by a high degree of dynamism that, along with the heterogeneity of computational devices and communication infrastructure, demand the development of a new range of applications that must be able to self-adapt dynamically and transparently according to changes in its execution environment. A computational grid i

19. A development environment based on adaptive decision tables. / Um ambiente de desenvolvimento baseado em tabelas de decisão adaptativas.
This work presents an application of adaptive technology to the decision making process applied in the business management and Decision Support Systems. To accomplish this goal, a development environment based on adaptive decision tables is proposed. This way, a user who is not familiar to the computing concepts, but that does know the decision making proces

20. Framework for computational interfacing and management of data acquistion systems / Framework para interface e gerenciamento computacional de sistemas de aquisiÃÃo de dados
Most of the data acquisition systems are based on dedicated hardware and software. Such strategy leads to major dificultes when one needs to expand or update certain features of the hardware, as this generally leads to substantial changes in the software and vice-versa. This work proposes the development of a framework for interfacing and management of data

22. Intelligent system to control voltage regulator relays / Sistema inteligente para controle de relés reguladores de tensão
This work presents an approach to voltage control in power distribution systems with load tap changers. Intelligent approaches are studied and applied in voltage regulator relay in order to improve the voltage profiles of the system. The proposal of this work is the addition of fuzzy modules in the conventional voltage regulator relays, which allows the expl

23. Alguns aspectos de tratamento de dependências de contexto em linguagem natural empregando tecnologia adaptativa. / Some aspects on natural language context dependencies handling using adaptive technology.
Since low-complexity language formalisms are too weak to handle NL, stronger formalisms are required, most of them resource demanding, hard to use or unpractical. Structured pushdown automata are excellent to represent regular and context-free aspects on NLs by allowing them to be split into regular layer (implemented as finite-state machines) and a context-

24. Development and application of shunt active filters for three-phase four-wire systems / Estudo e aplicação de filtros ativos paralelos para sistemas trifasicos com quatro fios
Electricity power quality has gained increased importance in the past few years. The growing number of power electronicsbased loads has created a preoccupation about harrnonic distortion in electric systems. Electricity power quality is an important issue both for energy utilities and consumers. Harrnonic poIlution may cause severe problems to electricity ut
