1. Analytical solution for nonlinear dynamic behavior of viscoelastic nano-plates modeled by consistent couple stress theory
Abstract This paper analyses the non-stationary free vibration and nonlinear dynamic behavior of the viscoelastic nano-plates. For this purpose, a size-dependent theory is developed in the framework of the consistent couple stress theory for viscoelastic materials. The previously presented modified couple stress theory was based on some consideration making

2. Evaluation of radiances generated by solving the radiative-transfer equation with different approaches
Radiative transfer is the main phenomenon in the basis of several relevant problems of scientific and technological interest. Examples of application of the mathematical and computational modeling of such phenomenon can be found in astronomy, environmental sciences, engineering and medicine among many different areas. The integro-differential equation known

3. A comparative study of the application of differential evolution and simulated annealing in radiative transfer problems
The radiative transfer phenomenon is modeled by an integro-differential equation known as Boltzmann equation. This equation describes mathematically the interaction of the radiation with the participating medium, i.e., a medium that may absorb, scatter and emit radiation. In this sense, this work presents a study regarding the estimation of radiative propert

4. Solução numérica de equações integro-diferenciais singulares / Numerical solution of singular integro-differential equation
A Teoria das equações integrais, desde a segunda metade do século XX, tem assumido um papel cada vez maior no âmbito de problemas aplicados. Com isso, surge a necessidade do desenvolvimento de métodos numéricos cada vez mais eficazes para a resolução deste tipo de equação. Isso tem como consequência a possibilidade de resolução de uma gama cada

5. A stability result via Carleman estimates for an inverse source problem related to a hyperbolic integro-differential equation
First we prove a Carleman estimate for a hyperbolic integro-differential equation. Next we apply such a result to identify a spatially dependent function in a source term by an (additional) single measurement on the boundary.

6. Inexistencia de blow-up hiperbolico simples para a equação quasi-geostrofica
Nonexistence of simple hyperbolic blow-up for the quasigeostrophic equation. This master dissertation deals with the quasigeostrophic equations, a system of integro-differential equations that has been proposed as a model for the process of large-scale front formation in the atmosphere. These equations have a structure that resembles the system of two dimens

7. Simulação da cinetica do crescimento de pontos quanticos semicondutores em vidros
The growth kinetics of pontos quânticos (QD) in a vitreous matrix is important because its linear and non linear optical properties depends on their sizes and dispersion. QD s are fabricated by melting the semiconductors elements together with the vitreous matrix. After melting, the glass is submitted to a thermal treatment to lower temperatures, (500- 600�

8. Modelo termodinamico para o aquecimento não-linear, a laser, e suas aplicações ao processamento de materiais
The subject of the computer modeling of the laser processing of materials continues to be highly topical in Materials Science. Basic to such an achievement was to have an well posed proposition to determine the time evolution of the temperature anywhere in the laser heated sample. Though models of such a kind abound in the literature, they are either rather
