Hardware Reconfigurável para Controladores Nebulosos.

Controle de processos é uma das muitas aplicações que aproveitam as vantagens do uso da teoria de conjuntos nebulosos. Nesse tipo de aplicação, o controlador é, geralmente, embutido no dispositivo controlado. Esta dissertação propõe uma arquitetura reconfigurável eficiente para controladores nebulosos embutidos. A arquitetura é parametrizável, de tal forma, que permite a configuração do controlador para que este possa ser usado na implementação de qualquer aplicação ou modelo nebuloso. Os parâmetros de configuração são: o número de variáveis de entrada (N); o número de variáveis de saída (M); o número de termos linguísticos (Q); e o número total de regras (P). A arquitetura proposta proporciona também a configuração das características que definem as regras e as funções de pertinência de cada variável de entrada e saída, permitindo a escalabilidade do projeto. A composição das premissas e consequentes das regras são configuráveis, de acordo com o controlador nebuloso objetivado. A arquitetura suporta funções de pertinência triangulares, mas pode ser estendida para aceitar outras formas, do tipo trapezoidal, sem grandes modificações. As características das funções de pertinência de cada termo linguístico, podem ser ajustadas de acordo com a definição do controlador nebuloso, permitindo o uso de triângulos. Virtualmente, não há limites máximos do número de regras ou de termos linguísticos empregados no modelo, bem como no número de variáveis de entrada e de saída. A macro-arquitetura do controlador proposto é composta por N blocos de fuzzificação, 1 bloco de inferência, M blocos de defuzzificação e N blocos referentes às características das funções de pertinência. Este último opera apenas durante a configuração do controlador. A função dos blocos de fuzzificação das variáveis de entrada é executada em paralelo, assim como, os cálculos realizados pelos blocos de defuzzificação das variáveis de saída. A paralelização das unidades de fuzzificação e defuzzificação permite acelerar o processo de obtenção da resposta final do controlador. Foram realizadas várias simulações para verificar o correto funcionamento do controlador, especificado em VHDL. Em um segundo momento, para avaliar o desempenho da arquitetura, o controlador foi sintetizado em FPGA e testado em seis aplicações para verificar sua reconfigurabilidade e escalabilidade. Os resultados obtidos foram comparados com os do MATLAB em cada aplicação implementada, para comprovar precisão do controlador.

Modelagem automática de sistemas fuzzy utilizando otimização por enxame de partículas.

Esta dissertaçãoo investiga a utilização de Particle Swarm Optimization (PSO) para a obtenção automática de sistemas fuzzy do tipo Mamdani, tendo como insumo apenas as definições das variáveis do problema, seus domínios e a função objetivo. Neste trabalho utilizam-se algumas técnicas conhecidas na tentativa de minimizar a obtenção de sistemas fuzzy que não sejam coerentes. As principais técnicas usadas são o método de Wang e Mendell, chamado de WM, para auxiliar na obtenção de regras, e os conceitos de clusterização para obtenção das funções de pertinência. Na função de avaliação proposta, considera-se não somente a acurácia do sistema fuzzy, através da medida do erro, mas também a sua interpretabilidade, através da medida da compacidade, que consiste da quantidade de regras e funções membro, da distinguibilidade, que permite evitar que as funções membro não se confundam, e da completude, que permite avaliar que as funções membro abranjam o máximo do domínio. O propósito deste trabalho consiste no desenvolvimento de um algoritmo baseado em PSO, cuja função de avaliação congregue todos esses objetivos. Com parâmetros bem definidos, o algoritmo pode ser utilizado em diversos tipos de problemas sem qualquer alteração, tornando totalmente automática a obtenção de sistemas fuzzy. Com este intuito, o algoritmo proposto é testado utilizando alguns problemas pré-selecionados, que foram classificados em dois grupos, com base no tipo de função: contínua ou discreta. Nos testes com funções contínuas, são utilizados sistemas tridimensionais, com duas variáveis de entrada e uma de saída, enquanto nos testes com funções discretas são utilizados problemas de classificação, sendo um com quatro variáveis e outro com seis variáveis de entrada. Os resultados gerados pelo algoritmo proposto são comparados com aqueles obtidos em outros trabalhos.

Charter and Party Boat Operators in the U.S. Gulf of Mexico: A Social Structure Perspective

To better address the charter and party boat fishery needs in the U.S. Gulf of Mexico, fishery managers must understand the linkages between the industry and other groups and organizations that affect its success. Gulf state charter and party boat operators were interviewed to ascertain the extent of their social network linkages, membership in community organizations, business community relationships, and linkages to information sources. Approximately one-third to one-half of the charter and party boat operators did not belong to local community organizations that could assist their business through tourism promotion or natural resource protection. Despite their limited integration in the community, the vast majority of operators gave and received referrals from other businesses. Of four major information sources, the National Weather Service and the County Marine Extension agents were rated highest and lowest, respectively, in mean importance to charter and party boat operators. Results suggest that business success can be enhanced by strengthening network ties between operators and local businesses, chambers of commerce, and tourism organizations. For this to occur, individual operators and charter/party boat organizations need to become more effective in representing industry interests. Informational linkages between industry and govemment agencies also need improvement.

Getting it right: incorporating social aspects into MPA planning and implementation

This brochure summarizes a series of case studies done in nine countries—Brazil, India, Indonesia, Mexico, Senegal, South Africa, Spain,Tanzania and Thailand—on the role of communities in the planning and implementation of marine protected areas (MPAs). The studies demonstrate that communities can be powerful allies in efforts for conservation and management of coastal and marine resources. They also underline the need for systematic attention, capacity building, funding and other resources for effective implementation of Programme Element 2 on governance, participation, equity, and benefit sharing of the Programme of Work on Protected Areas (PoWPA) of the Convention on Biological Diversity (CBD).

Basic steps in the production of the African catfish seed

A typical production cycle for African catfish farming begins with a selection of fingerlings or juvenile fish of good quality for brood stock development. Fish are selected from a family or grow out stock basing on records of the origin,age, strain and performance history of the parents or from the wild in this brochure, we explain the basic steps and requirements a farmer needs in order to achieve good results in the hatchery.
