The space of n-sided polygons embedded in euclidean three-space consists of a smoothmanifold in which points correspond to piecewise linear or “geometric” knots, while pathscorrespond to isotopies which preserve the geometric ...

In this article we introduce a concept based on the differential constraints methodto examine the closure procedure in Turbulence Models. We show how this conceptmay be applied to study the problem of interaction and mixing ...

The May population model consider a satiate parameter over the predators andhas an unstable equilibrium state surrounded by a limit cycle. This work gives acontrol strategy driven to disturb the model in such way that the ...

We present in this work a natural Interacting Particle System (IPS) approach formodeling and studying the asymptotic behavior of Genetic Algorithms (GAs). In thismodel, a population is seen as a distribution (or measure) ...

 We present some known properties of bk(n, p) the kth inverse moment of a positive binomial variate. Additional properties of this function and new bounds are derived. Keywords:  Probability, statistics, life contingencies, ...
