1. Non-parametric edge detection in speckled imagery
This thesis proposes a non-parametric technique for boundary detection in speckled imagery. Synthetic Aperture Radar (SAR), sonar, B-ultrasound and laser imagery is corrupted by a signal-dependent non-additive noise called speckle. Several statistical models have been proposed to describe such a noise, thus of specialized techniques for image improvement and

2. Efeitos genotóxicos e mutagênicos da fração solúvel do óleo diesel em uma espécie de peixe Neotropical
ABSTRACT The present work shows results of the mutagenicity and genotoxicity evaluation of the comercial diesel oil fraction on freshwater fishes Prochilodus lineatus (Characiformes: Prochilodontidae), ordinarily known as curimba. The water containing the diesel oil soluble fraction was obtained through simulation of the spill in tropical environment. In the

3. Métodos atuariais aplicados à determinação da taxa de prêmio de contratos de seguro agrícola: um estudo de caso. / Actuarial methods applied to the determination of the premium rate of crop insurance contracts: a case study.
This research analyses alternative methods of pricing agricultural insurance contract based on regional yields. The premium rate is calculated using three different approaches: nonparametric method to estimate the density of the agricultural yield; parametric approach fitting the Normal and Beta distributions; and, hierarchical Bayesian models. The data gene
