37. MODELAGEM DO MÓDULO DE YOUNG EM NANOCOMPÓSITOS ATRAVÉS DE INTELIGÊNCIA COMPUTACIONAL / MODELING YOUNGS MODULUS OF NANOCOMPOSITES THROUGH COMPUTATIONAL INTELLIGENCE
Composite materials became very popular due to its improvements on certain properties achieved from the mixture of two different components. Recently, the use of nanofillers in the manufacture of composites has been widely studied due to the improvement of properties at low concentrations of nanofillers, enabling the creation of lightweight materials. Some o

38. Análise de similaridades de modelagem no emprego de técnicas conexionistas e evolutivas da inteligência computacional visando à resolução de problemas de otimização combinatorial: estudo de caso - problema do caixeiro viajante. / Similarity analysis for conexionist and evolutionary tecniques of the computational intelligence fild focused on the resolution of combinatorial optimization problems: case study - traveling salesman problem.
An analysis between the Evolutionary Computation and the Neural Computation fields was presented in order to identify similarities and mappings between the theories. In the analysis, the identification of similarities between the models designed for combinatorial optimization problems results in a comparison between the Boltzmann Machine and the Two-Membered

40. SIMULAÇÃO E PROJETO DE CÉLULAS SOLARES COM POÇOS QUÂNTICOS DE GAAS/ALGAAS AUXILIADO POR ALGORITMOS GENÉTICOS / SIMULATION AND DESIGN OF GAAS/ALGAAS QUANTUM WELL SOLAR CELLS AIDED BY GENETIC ALGORITHM
A energia é assunto estratégico para a grande maioria dos países e indústrias no mundo. O consumo atual energético é de 138,32 TWh por ano e é previsto um aumento de 44% até o ano de 2030 o que demonstra um mercado em expansão. Porém, a sociedade atual exige soluções energéticas que causem o menor impacto ambiental possível, colocando em dúvid

43. Unsupervised methods of classifying remotely sensed imges using Kohonen self-organizing maps / Metodos de classificação não-supervisionada de imagens de sensoriamento remoto usando mapas auto-organizaveis de Kohonen
This thesis proposes new methods of unsupervised classification for remotely sensed images which particularly exploit the characteristics and properties of the Kohonen Self-Organizing Map (SOM). The key point is to execute the clustering process through a set of prototypes of SOM instead of analyzing directly the original patterns of the image. This strategy

44. Synthetic actors in serious games: an Organizational Psychology based approach / Atores sintéticos em jogos sérios: uma abordagem baseada em Psicologia Organizacional
Modeling Synthetic actors (SA) is currently one of the research areas within Artificial Intelligence. These actors are a specific kind of intelligent agents are able to perceive the environment and act on it on the basis of their reasoning capabilities and their personality (which dictates a particular way of interacting with the environment surrounding them

45. Sistema de suporte a decisão para analise e previsão de carga por barramento / Decision support system to the analysis and bus load forecasting
In a power operation system there are many variables that can Influence the execution of t ho control routines. The attendance of these variables is very important to aid the processes in the safe operation of the system. In the electric system the bus load level is an important variable in operation planning step. Accurate Information on the load level In e

46. Observadores inteligentes de estado : propostas / Intelligent state observers : proposals
The state observer problem arises from the necessity of controlling plants whose state can not be measured. Usually dynamic model based observers are used to solve this problem, for estimating unknown state. In this thesis an alternative solution for this problem is presented. Various proposals for intelligent observers are made based on mappings between sub

47. A semiotic-oriented development process for intelligence augmentation systems / Uma metodologia de desenvolvimento de sistemas de amplificação de inteligencia orientada a semiotica
Problemas não estruturados são problemas que dependem de variáveis não quantificáveis, não mensuráveis, imprecisas ou incertas, e que podem depender de fatores culturais, políticos, sociais, econômicos e ambientais. Sistemas ?Otimizantes?, onde há uma forte dependência na lógica e fraca interação homem-máquina, geralmente não são capazes de

48. Synthesis of autonomous controllers in mobile robotics through bio-inspired computing / Sintese de controladores autonomos em robotica movel por meio de computação bio-inspirada
Novel techniques for autonomous robot navigation aim at fulfilling the growing demand for mobile robots in multiple segments of society and in a plethora of tasks. The challenges involved in developing the system which controls the robot allow to say that the intelligence embedded in the current robots is found to be still incipient and limited. In this work
