13. Developmental genetic analysis of fruit shape traits under different environmental conditions in sponge gourd (Luffa cylindrical (L) Roem. Violales, Cucurbitaceae)
Analysis of genetic main effects and genotype × environment (GE) interaction effects for the fruit shape traits fruit length and fruit circumference in the sponge gourd (Luffa cylindrical (L) Roem. Violales, Cucurbitaceae) was conducted for diallel cross data from two planting seasons. A genetic model including fruit direct effects and maternal effects and

14. Medidas de assimetria bivariada e dependência local. / Measures of bivariate asymmetry and local dependence.
Esta tese trata de dois assuntos importantes na teoria de risco: o fenômeno da dependência local e a identificação e mensuração de assimetrias apresentadas pelos dados. A primeira parte trata de dependência local, sendo abordadas algumas medidas já analisadas na literatura. Versões locais dos coeficientes de Kendall e Spearman , baseadas na distribu

15. AnÃlise de focalizaÃÃo e sua aplicaÃÃo para o caso do Programa Bolsa FamÃlia
Given the persistence of poverty in the world social policies direct to reduce its intensity have been adopted recently. I particular, Brazil has adopted direct conditional income transference programs. These policies resulted in poverty and inequaliy reductions. But several studies showed that these policies present targeting problems, that is, the poor are

16. THE ECONOMIC VALUE OF CONSTANT AND DYNAMIC CONDITIONAL CORRELATION MODEL / O VALOR ECONÔMICO DOS MODELOS DE CORRELAÇÃO CONDICIONAL CONSTANTE E DINÂMICA
At Fleming, Kirby e Ostdiek (2001), evidences are found that volatility timming models, have signicant economic value when comparing with the simple unconditional variance matrix, in a framework of portfolio optimization. Going further, this work analyze if the more complex Constant (CCC) and Dynamic (DCC) Conditional Corrrelation models, suggested respectiv

17. Factors associated with Intra-Uterine Growth Retardation newborns in public maternity in Salvador. / Fatores associados ao retardo de crescimento intra-uterino em recém nascidos em maternidades públicas da cidade de Salvador-Bahia.
Factors associated with Intra-Uterine Growth Retardation have not been fully clarified. Small newborns for gestational age have shown different hematological parameters compared appropriate newborns for gestational and preterm newborns. There are also methodological limitations concerning accuracy to determine gestational age. Objectives: To determine factor

18. Análise de imagens na avaliação do comportamento, do bem-estar e do desempenho de pintos de corte submetidos a diferentes sistemas de aquecimento / Images analysis in the behavior evaluation, welfare and performance of the young chicken submitted to different heating systems
Currently Brazil is the country that owns the biggest number of relative information to the thermal requirement of opened buildings in summer conditions of tropical climates. However, exists the need of investigations concerning the energy expense, efficiency of the heating systems, animal welfare and contamination levels of the air for the architectural and

19. Contagio em mercados financeiros emergentes / Emerging financial markets contagion
The issue of contagion has been one of the most debated in the international finance literature in the last years. Although there is no general agreement regarding the definition of contagion, it is known that this issue is related to the fact that crisis started in one country tend to propagate to other countries. Therefore, a measure used as an indication

20. The impact of the sugar markets and American oil in the volatileness of the Brazilian sugar / O impacto dos mercados de açúcar e petróleo americano na volatilidade do açúcar brasileiro
The alcohol fuel became a real and viable alternative to the growing petroleum prices in the global economy. However the production of this kind of fuel requires a great amount of sugar cane, of which Brazil is the major world-wide producer. There are two major outcomes of sugar cane: alcohol fuel and sugar. Whereas the alcohol fuel is a clear substitute to

21. Estimativa das funções de recuperação de reservas minerais usando copulas / Estimation of recovers function of mineral reserves using copulas
The aim of this thesis was to develop the applied methodology of copulas in the problem of conditional reserves estimation. The copulas have a different approach from sequential gaussian simulation and in this thesis was used to correct the tonnage and ore quantity of a mining project. It is presented a theoretical summary that is the bases to the study of c

22. Mapeamento de áreas susceptíveis a escorregamentos no município de Caraguatatuba (SP) usando técnicas de sensoriamento remoto e SIG / Landslide susceptibility mapping in Caraguatatuba (SP) municipality using remote sensing and gis techniques
The objective of the present research was the development of a quantitative approach for landslide susceptibility mapping using remote sensing and GIS techniques. In order to determine the best products for identifying landslide scars, six imagery fusion techniques (Brovey, HSV, PCA, IHS and two Wavelets) were evaluated and many geographical inference approa

23. Evaluating factorial kriging for seismic attributes filtering: a geostatistical filter applied to reservoir characterization / Avaliação da krigagem fatorial na filtragem de atributos sismicos : um filtro geoestatistico aplicado a caracterização de reservatorios
In this dissertation the Factorial Kriging analysis for the filtering of seismic attributes applied to reservoir characterizatÍon is considered. Factorial Kriging works in the spatial domain in a similar way to the Spectral Analysis in the frequency domain. The incorporation of filtered attributes via External Drift Kriging and Collocated Cokriging in the e

24. MODELO BAYESIANO PARA ESTIMAR AS CONTRIBUIÇÕES INDIVIDUAIS DE APARELHOS ELETRODOMÉSTICOS NO CONSUMO RESIDENCIAL DE ENERGIA ELÉTRICA / A BAYESIAN PROCEDUCE TO ESTIMATE THE INDIVIDUAL CONTRIBUTION OF INDIVIDUAL END USES IN RESIDENCIAL ELECTRICAL ENERGY CONSUMPTION
The present dissertation investigates the use of multivariate regression models from a Bayesian point of view. These models were used to estimate the electric load behavior of household end uses. A conditional demand structure was used considering its application to the demand management of the residential and commercial consumers. This work is divided in th
