1. Estudo de um formalismo para discretizar eficientemente as equações integrais do Método da Coordenada Geradora Hartree-Fock / The study of a formalism to discretize efficiently the integral equations of the generator coordinate Hartree-Fock method
The search for high quality basis set is made by several groups since the quality of the basis sets is a very important factor to obtain accurate results for atomic and molecular properties. The basis sets used in this work are designed by using the polynomial Generate Coordinate Method and were constructed with the aim to improve the flexibility of a basis

2. A mathematical formulation of the boundary integral equations for a compressible stokes flow
A general boundary integral formulation for compressible Stokes flows is theoretically described within the framework of hydrodynamic potentials. The integral equation is implemented numerically to the study of drop expansion in compressible viscous flows. Marker point positions on the drop interface are involved by using the boundary integral method for cal

3. ANÁLISE DE DESEMPENHO DA TÉCNICA DE MULTIGRID EM PROBLEMAS DE FENÔMENOS DE TRANSPORTE / ANÁLISIS DEL DESEMPEÑO DE LA TÉCNICA MULTIGRID EN PROBLEMAS DE FENÓMENOS DE TRANSPORTE / PERFORMANCE ANALYSIS OF THE MULTIGRID TECHNIQUE FOR TRANSPORT PHENOMENA PROBLEMS
The numerical solution of fluid flows problems with heat transfer requires the solution of a set of coupled non- linear partial differencial equations. The major computational effort in solving these equations is due to the solution of the algebraic systems resultant from the discretization of the conservation equations. The convergence rate of iterative met

4. Solução de problemas poroelasticos atraves do metodo dos elementos de contorno
The Biot s theory af poroelasticity is revisited making it more easily applicable to practical problems. The parameters used by Biot are redefined as functions of other ones with an easier and simpler physical interpretation. This helps their determination and the understanding of poroelastic phenomena. The equations that govern the theory of quasi-static li

5. Desenvolvimento de funções de base GTO : aplicação de metodo da coordenada geradora atraves da tecnica de discretização integral otimizada
A systematic approach to obtaining GTO basis sets from atomic calculations at the Hartree-Fock leveI, employing the principIes of the Generator Coordinate Method (GCM) and the Optimized Integral Discretization technique (OID) is proposed. The discussion is centered on the formulation of a finite discretized space of GTO functions. Special attention is paid t
