We use asymptotic analysis to describe in amore systematic way the behavior at the infinity of functions in the convex and quasiconvex case. Starting from the formulae for the firstand second-order asymptotic function in the convex case, we introduce similar notions suitable for dealing with quasiconvex functions. Afterward, by using such notions, a class of quasiconvex vector mappings under wh...

In this paper it is described a method to compute the distance between sets, that implies the formation of distance functions different from Hausdorff metric. Two functions with metric properties, which describe quantitatively distances between sets, are formed. First function can be used for sets arbitrary situated from each other. Second distance is more suited for sets clustered by rank link...

This article reports an initial validation of an instrument that measures basic interviewing skills and compares its psychometric results with another instrument that has been used more frequently to measure similar skills. Four field supervisors rated 30 students’ videotaped interviews (N=120) using two instruments, the validation, and a comparison instrument. The current validation instrument...

Mathematical data-mining techniques to generate a representative set of protein fragments are described. Protein fragments are used as search models within the macromolecular phasing method of molecular replacement to attempt to phase protein data without a homologous model correctly. Preliminary investigations using these fragments indicate that molecular replacement with AMoRe is not sensitiv...

Nem sempre uma boa ideia pode ser um bom negócio! Essa é a frase chave que permeia este caso para ensino. Onde empresário muda de ramo atividade apostando em inovadora, mas investe no negócio desconhecendo parcialmente o mercado irá atuar devido à falta diagnóstico e planejamento, ocasiona infortúnios poderiam ter sido identificados antes mesmo sua concepção assim evitados.
