Biologia reprodutiva e ausência de frutificação de Aloe saponaria (Aiton) Haw. (Xanthorrhoeaceae) fora do local de origem

Universidade Federal de Juiz de Fora

A universal minimal spinor set of linear differential equations describing anyons and ordinary integer and half-integer spin fields is constructed with the help of deformed Heisenberg algebra with reflection. The construction is generalized to some d = 2 + 1 supersymmetric field systems. Quadratic and linear forms of action functionals are found for the universal minimal as well as for supersym...

Medida de Correlação entre Padrões Pontuais de Origem-destino

When we use origin-destination survey data, we can be interested in verifying if the link between the two point patterns is or is not a result of randomness. In this paper we present a new measure of bivariate processes linking strength, find out its probability distribution and apply the method to data of car thefts location and its retrieving locations in Belo Horizonte. Resumo. Quando se uti...

Caracterização do comportamento de usuários e precificação de tráfego de internet de banda larga

Broadband user behavior characterization can lead to better understanding and identifying different classes of users, defined by user request patterns. This characterization could help broadband carriers capacity management and planning efforts. Different service request patterns require different service prices. Nevertheless, the main pricing scheme used by broadband ISPs (Internet Service Pro...

Desenvolvimento de um sistema de análise de imagem para quantificação do tamanho e distribuição de partículas de desgaste

This paper describes the development of an image analysis system for wear particles found in industrial equipment lubricating oil. Hence, it was utilized an image acquisition system to capture image samples of the oil held in filter membranes. An analytical methodology was also developed to classify the particles quantitatively and qualitatively, relating them to the wear mode where they had be...
