1. USE OF CONTINUED ITERATION ON THE REDUCTION OF ITERATIONS OF THE INTERIOR POINT METHOD
ABSTRACT Interior point methods have been widely used to determine the solution of large-scale linear programming problems. The predictor-corrector method stands out among all variations of interior point methods due to its efficiency and fast convergence. In each iteration it is necessary to solve two linear systems to determine the predictor-corrector dire

2. Static and dynamic analysis of reinforced concrete shells
The objective of this work is to provide a reliable numerical model using the finite element method (FEM) for the static and dynamic analysis of reinforced concrete (RC) shells. For this purpose two independently computer programs based on plasticity and viscoplasticity theories are developed. The well known degenerated shell element is used for the static a

3. Iteração continuada aplicada ao método de pontos interiores / Continued iteration applied to interior points method
Interior point methods have been widely used in the solution of large linear programming problems. The predictor corrector method, among ali interior point variants, is one of mostly used due to its efficiency and convergence properties. This method needs the solution of two linear systems to determine the predictor corrector direction, in each iteration. So

4. Um novo metodo preditor-corretor para fluxo de potencia otimo / A new predictor-corrector method for optimal power flow
Um método de pontos interiores preditor-eorretor é desenvolvido para o problema de fluxo de potência ótimo ativo-reativo. As tensões são representadas em coordenadas cartesianas ao invés de coordenadas polares, pois estas, sendo quadráticas, permitem correções não lineares nas condições de factibilidade primai e dual e não apenas nas de complem

5. Estrategias de segunda ordem para problemas de complementaridade / Second order strategies for complementarity problems
In this work we reformulate the generalized nonlinear complementarity problem (GNCP) in polyhedral cones as a nonlinear system with nonnegativity in some variables and propose the resolution of such reformulation through interior-point methods. In particular we define two algorithms and prove the local convergence of these algorithms under standard assumptio

6. Minimum-time anti-swing control of gantry cranes using linear programming. / Controle anti-oscilatório de tempo mínimo para guindaste usando a programação linear.
The problem of minimum-time anti-swing transfer of a load in a ship-to-pier gantry crane is investigated in this work. The load is assumed to be initially at rest at the vertical position at the loading point above the ship and equally at rest at the unloading point above the hopper. The trolley is also assumed to be at rest at both points. A complete model

"Métodos de pontos interiores aplicados ao pré-despacho de um sistema hidroelétrico usando o princípio de mínimo esforço - comparação com o modelo de fluxo em redes" / Interior point methods applied to the predispatch of a hydroelectric system using the minimum effort principle - comparison with the network flow model
Neste trabalho, os métodos de pontos interiores primal-dual e preditor corretor são estudados e desenvolvidos para o problema de minimização de custos na geração e perdas na transmissão do pré-despacho DC (fluxo de carga em corrente contínua) de um sistema de potência hidroelétrico, com base no modelo de fluxo em redes e no princípio do mínimo e

9. Numerical model for the simulation of fixed wings aeroelastic response
A numerical model for the simulation of fixed wings aeroelastic response is presented. The methodology used in the work is to treat the aerodynamics and the structural dynamics separately and then couple them in the equations of motion. The dynamic characterization of the wing structure is done by the finite element method and the equations of motion are wri

A numerical model for the simulation of the aeroelastic response of fixed wings is proposed. The methodology used in the work is to treat the aerodynamic and the structural dynamics separately and then couple them in the equation of motion. The dynamic characterization of a prototype wing is done by the finite element method and the equation of motion is wri

11. Escolha adiada do parametro de penalização e do tamanho de passo em algoritmos de pontos interiores
We study, in the context of interior-point methods for linear programming, some possible advantages of postponing the choice of the per. ",lty parameter and the step length, which happens both when we apply Newton s method to the Karush-Kuhn-Thcker system and when we apply a predictor-corrector scheme. We show that for a Newton or a strictly predictor step t

12. Numerical simulation of incompressible viscous flow in deforming domains
We present a second-order accurate finite difference method for numerical solution of the incompressible Navier-Stokes equations in deforming domains. Our approach is a generalization of the Bell-Colella-Glaz predictor–corrector method for incompressible flow. In order to treat the time-dependence and inhomogeneities in the incompressibility constraint int
