1. A fault location method using Lamb waves and discrete wavelet transform
Non-destructive evaluation methods and signal process techniques are important steps in structural health monitoring systems to assess the structure integrity. This paper presents a method for fault location in aluminum beams based on time of flight of Lamb waves. The dynamic response signal captured from the structure was processed using the discrete wavele

2. Metodologia para implementação de controle supervisório modular local em controladores lógicos programáveis / Methodology for implementation of supervisory control local modular in programmable logic control
Currently, manufacturing automation has assumed an increasingly important role within the industry and the problems of automated control systems have become increasingly complex. Thus, the traditional use of empirical methods heavily base on the experience of the programmer can lead to inappropriate or ineffective solutions. In this case, the Supervisory Con

3. Diffuse Iris Melanoma in a Cat
Background: Diffuse iris melanoma is rare, although is the most common primary intraocular neoplasm in cats, and is an unusual variant of anterior uveal melanoma. This neoplasm is malignant with high potential methastazed. Affects olders cats without breed or sex predisposition. The diagnosis can be made with fine needle aspiration cytology of anterior segme

4. Estudo de alguns metodos determinsticos de otimização irrestrita / Study of some deterministic methods for unconstrained optimization
In this work some classical methods of linear search for unconstrained optimization are studied. The main mathematical formulations for the optimization problem are presented. Two strategies, linear search and trust region, for the algorithm to move from one iteration to another are discussed. Furthermore, the main considerations about the choice of step len

5. Amenidades locais versus oportunidades econÃmicas: estimando a propensÃo marginal a pagar pelas Amenidades para as RegiÃes Metropolitanas do Brasil
This dissertation estimates the marginal willingness to pay (MWTP) to local amenities and constructs a ranking of quality of life in Brazilian Metropolitan Regions (MRs). The theoretical approach is based in location decision model and three methods are used to calculate the amenity quality index, the Hedonic method suggested for Roback (1982); Kahn (1995) m

6. Aplicação de um procedimento usando preferência declarada para a estimativa do valor do tempo de viagem de motoristas em uma escolha entre rotas rodoviárias pedagiadas e não pedagiadas. / Application of a procedure using stated preference for value of travel time estimation in a choice context involving tolled and non-tolled routes.
This dissertation is based on the application of an empirical procedure using stated preference techniques for the estimation of the value of travel time for drivers in regional trips, in the context of a choice between tolled and non-tolled routes. It first reviews the theoretical and the empirical approaches for the valuation of travel time and then presen

7. ENHANCEMENT OF IMAGES IN THE TRANSFORM DOMAIN / REALCE DE IMAGENS NO DOMÍNIO DA TRANSFORMADA
This Dissertation is aimed at the development of new enhancement techniques applied in the transform domain. The study of the bidimensional transforms motivated the development of techniques based on these mathematical tools. The comparative analysis between the enhancement methods in the spatial domain and in the transform domain revealed the advantages of
