Perseguição e Fuga em Modelos Presa-Predador
(Universidade Federal de Santa Maria, 2010-03-04)
The main purpose of this dissertation is to propose and analyze the effects of pursuit and evasion on predator-prey spatiotemporal dynamics. We use a Coupled Map Lattices formulation in which a system of difference equations ...
Pontos Helicoidais e Vértices de Darboux de Curvas no Espaço Euclidiano
(Universidade Federal de Santa Maria, 2010-03-11)
The main aim of this work is a study about twistings points and Darboux vertices of n-space curves. We define the concept of twisting of a n-space curve as flattening point of its tangent indicatrix and show that is ...
MÚLTIPLAS ESCALAS EM INTERAÇÕES PRESA-PREDADOR
(Universidade Federal de Santa Maria, 2010-03-05)
The main purpose of this dissertation was to analyze the occurrence of two time scales in predator-prey systems. Initially, we proposed two discrete models without spatial structure. The first model considers fast vital ...
O TEOREMA DE CAUCHY NA MECÂNICA DOS FLUIDOS
(Universidade Federal de Santa Maria, 2010-12-21)
The present work shows Cauchy's Theorem on its classical form, and it has the objective of weakening their statements, and provides aplications in continuum mechanics. The metodology used here is the axiomatic, that is, a ...
