FORMULACÃO UNIFICADA PARA MODELOS CIN�ETICOS DERIVADOS DA EQUAÇÃO DE BOLTZMANN COM CONDIÇÕES DE CONTORNO GENERALIZADAS
(Universidade Federal de Santa Maria, 2012-02-28)
In this paper, we present numerical results obtained from the FORTRAN language for physical quantities of interest such as velocity profile, pro�le, heat ow rate, particle ow rate,heat ux and pressure tensor component. The ...
A FILTRAÇÃO STANDARD DE UMA ÁLGEBRA DE HOPF
(Universidade Federal de Santa Maria, 2014-03-25)
In this work we present the lifting method [AS2], which is used to classify certain class of Hopf algebras. Since this method is based on the coradical filtration, it can be used just for those Hopf algebras satisfying the ...
PARES ADMISSÍVEIS, SISTEMAS ADMISSÍVEIS E BIÁLGEBRAS NA CATEGORIA DOS MÓDULOS DE YETTER-DRINFELD
(Universidade Federal de Santa Maria, 2014-03-19)
The purpose of this work is to study the relationships between admissible pairs, systems admissible and bialgebras in the category of Yetter-Drinfeld modules, as well as some properties of the Hopf algebra associated (via ...
ESTUDO DO PRODUTO MATRICIAL POR MEIO DO MÉTODO DOS MÍNIMOS QUADRADOS: UMA ABORDAGEM DESTINADA AO ENSINO MÉDIO
(Universidade Federal de Santa Maria, 2014-04-22)
It has always been a challenge for math teachers to motivate students nowadays, with access to new technologies, this becomes and even greater challenge. One of the strategies that can be utilized in trying to increase the ...
UM MODELO DE REDES DE MAPAS ACOPLADOS PARA UM SISTEMA PRAGA-PREDADOR-INSETICIDA
(Universidade Federal de Santa Maria, 2016-08-24)
This research is inserted in the Biomathematics Research Group of the Programa de Pós-Graduação em Matemática of the Universidade Federal de Santa Maria-RS. It consists in the study of a discrete model for a prey-predato ...
O problema de Dirichlet para a equação da hipersuperfícies mínimas em domínios limitados
(Universidade Federal de Santa Maria, 2014-07-22)
In this work we study the classical results of existence and non-existence of solutions for the Dirichlet problem for the minimal hypersurfaces equation in bounded domains of Rn due to Jenkins-Serrin .
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 ...
ESTUDO DA DIN AMICA DE UM G´AS CONFINADO EM PLACAS PARALELAS HETEROG ENEAS UTILIZANDO O MODELO S
(Universidade Federal de Santa Maria, 2011-05-18)
In this work, an analytical version of the method of discrete ordinates (ADO) is used in developing solutions to problems of rarefied gases confined by two infinite parallel plates with different chemical constitutions, ...
Gráficos de curvatura média constante com bordo prescrito satisfazendo a condição de declividade limitada
(Universidade Federal de Santa Maria, 2011-04-08)
We study problems of existence and uniqueness of constant mean curvature surfaces with prescribed boundary satisfying the bounded slope condition. The surfaces are given as Euclidean graphs in R3 and as parabolic graphs ...
Superfícies duplamente conexas de curvatura média constante com bordo prescrito em planos paralelos
(Universidade Federal de Santa Maria, 2008-12-12)
In this work we presented some existence results about constant mean curvature surfaces in R³ with prescribed boundary in parallel planes, topologically an annulus, that are obtained by solving Dirichlet s problems for ...
