Existência e unicidade de solução global para um modelo termoelástico com domínio ilimitado
(Universidade Federal de Santa Maria, 2023-08-30)
The main objective of this dissertation is to demonstrate the existence of a global solution
for a system of partial differential equations of the hyperbolic type. The equation studied
is a formulation of the heat equation ...
A solução fundamental no cálculo da resposta forçada de uma viga Euler-Bernoulli sobre fundação elástica e com condições de contorno não-clássicas
(Universidade Federal de Santa Maria, 2023-10-26)
In this work we consider an Euler-Bernoulli beam on elastic foundation. The solution to
problems with and without external force was obtained through modal analysis and the fundamental
solution was used to write the ...
Um modelo SIS com taxas de recuperação e infecção variáveis
(Universidade Federal de Santa Maria, 2023-10-31)
In this dissertation we present a qualitative theoretical study of modifications to the SIS
epidemiological model for infectious diseases that do not confer immunity. We first study the
classic SIS model, which considers ...
Um modelo SIR com duas cepas circulantes
(Universidade Federal de Santa Maria, 2023-10-27)
To understand the evolution of many diseases such as influenza and COVID-19, for
example, it is necessary to consider the presence of multiple strains of the pathogen.
Models with multiple strains of the disease-causing ...
