1. Uma contribuiÃÃo ao problema de seleÃÃo de modelos neurais usando o princÃpio de mÃxima correlaÃÃo dos erros / A contribution to the problem of selection of neural models using the beginning of maximum correlation of the errors
PropÃe-se nesta tese um mÃtodo de poda de pesos para redes Perceptron Multicamadas (MLP). TÃcnicas clÃssicas de poda convencionais, tais como Optimal Brain Surgeon(OBS) e Optimal Brain Damage(OBD), baseiam-se na anÃlise de sensibilidade de cada peso da rede, o que requer a determinaÃÃo da inversa da matriz Hessiana da funÃÃo-custo. A inversÃo da ma

2. Crown dynamics and growth on eucalypt clones stands submitted to artificial pruning in an agroforestry system / Dinâmica de copa e crescimento de clones de eucalipto submetidos a desrama em sistema agroflorestal
The crown dynamic, growth and time spent to prune were evaluated in two eucalypt clones stands, in an agroforestry system, in a 9.5 x 4.0 m spacing, in Vazante, MG (1736 S, 4642 W and altitude of 550m). Pruning treatments included control and removal of one third or one fourth of the plant live crown height, with or without removal of some thick branches abo

3. Extensões e aplicações de redes neuro-imunológicas / Extensions and applications of neuro-immune network
This thesis considers the extension and development of immune-inspired tools. The developed tools are devoted to the resolution of clustering and classification problems with binary or real-valued data attributes. Inspired by ideas of the immune system, the considered algorithms have produced robust and parsimonious solutions. A common feature in the develop

4. Canopy structure and growth after thinning in a stand of eucalypt clone submitted to artificial pruning / Estrutura do dossel e crescimento após desbaste em povoamento de clone de eucalipto desramado
A estrutura do dossel e o crescimento de plantas de clone de Eucalyptus grandis W. Hill ex Maiden, submetidas a diferentes intensidades e freqüência de desrama, iniciando aos 16, 20 e 28 meses de idade, e ao desbaste (0 e 35% do número total de mudas plantadas), aos 55 meses de idade, foram avaliados entre 55 e 93 meses de idade, na região de cerrado. O

5. Growth and wood quality evaluation of Eucalyptus grandis [HILL EX MAIDEN] submitted to artificial pruning / Crescimento e qualidade da madeira para serraria em clone de Eucalyptus grandis [HILL EX MAIDEN] submetido à desrama artificial
O presente estudo teve como objetivo avaliar a influência de desrama da copa viva de plantas de clone de Eucalyptus grandis sobre o crescimento e a qualidade da madeira para serraria. O experimento foi desenvolvido em povoamento estabelecido em novembro de 1998, no espaçamento 3 x 3 m, com o clone 24504 de Eucalyptus grandis [HILL EX MAIDEN], na Companhia

6. RHeSumaRST: um sumarizador automático de estruturas RST.
This work presents an automatic summarization model based on both the Rhetorical Structure Theory RST and the Veins Theory VT. RST allows inter-relating discourse units by means of rhetorical relations. These, in turn, mirror meaning relations between those units. Adding to RST, VT delimits the domain of referential accessibility of each discourse unit of an

7. Production of Niagara Rosada grape under defoliation after harvest. / Produção da videira Niagara Rosada em função da desfolha após a colheita.
The foliage presence, on the grape plant, after harvest is very important, because it is in this period that carbohydrate will be accumulated to be used in the next season by the plant. The objective of this work was to study the influence of the defoliation after the harvest. It was established the following artificial defoliation levels: 25% and 50%, with

8. Growth, crown dynamic and wood quality for sawmill of Eucalyptus grandis [HILL EX MAIDEN] clone submitted to artificial pruning / Crescimento, dinâmica de copa e qualidade da madeira para serraria de clone de Eucalyptus grandis [HILL EX MAIDEN] submetido à desrama artificial
Plants of the clone 24504 of Eucalyptus grandis [HILL ex-MAIDEN] established at 3.0 x 3.0 m spacing, in Southeastern Brazil, were submitted to different artificial pruning intensities starting at two seasons: dry season, with the first pruning intervention occurring in July 2000 in plants aged 20 months and, wet season, with the first pruning intervention oc
