2. PDE models associated to fuzzy logic ans statistical methods in the treatment of uncertainties : an application on food-and-mooth disease / Modelos de EDP integrados a logica Fuzzy e metodos probabilisticos no tratamento de incertezas : uma aplicação a febre aftosa em bovinos
The foot-and-mouth disease is a viral, infectum contagious pathology, characterized for a scene full of inherent uncertainties, resultants of the influence of social, economic and environmental factors related to the transmission process, that can occur for direct and indirect means. In Epidemiology, great part of the uncertainties are treated either by the

3. Modelling and evaluation of industrial plants useful life extension / Modelagem e avaliação da extensão da vida útil de plantas industriais
During the useful life of an industrial plant, the failure occurrence follows an exponential distribution. However, the aging process in an industrial plant generates an increase of the failure number. The failure probability is a rating for the maintenance stopping process. In this paper, an statistical method for the assessment of the failure probability a
