1. A Full Rank Condition for Continuous-Time Optimization Problems with Equality and Inequality Constraints
RESUMO Condições necessárias do tipo Karush-Kuhn-Tucker de primeira e segunda ordens são estabelecidas para problemas de otimização com tempo contínuo com restrições de igualdade e desigualdade. Uma condição de regularidade tipo posto completo juntamente com um teorema da função implícita uniforme são usados com a finalidade de se alcançar ta

2. OPTIMALITY AND PARAMETRIC DUALITY FOR NONSMOOTH MINIMAX FRACTIONAL PROGRAMMING PROBLEMS INVOLVING L-INVEX-INFINE FUNCTIONS
ABSTRACT The Karush-Kuhn-Tucker type necessary optimality conditions are given for the nonsmooth minimax fractional programming problem with inequality and equality constraints. Subsequently, based on the idea of L-invex-infine functions defined in terms of the limiting/Mordukhovich subdifferential of locally Lipschitz functions, we obtain sufficient optimal

3. Bézier control points method to solve constrained quadratic optimal control of time varying linear systems
A computational method based on Bézier control points is presented to solve optimal control problems governed by time varying linear dynamical systems subject to terminal state equality constraints and state inequality constraints. The method approximates each of the system state variables and each of the control variables by a Bézier curve of unknown cont

4. The inequality curse: constraints and political discretion
We live in an unjust world characterized by economic inequality. No liberal theory of justice is able to justify it. Inequality is not “solved” with equality of opportunity or meritocracy. Nor by the socialist and republican critique. The poor will have to count with them and with democracy to make social progress reality. In their political struggle, th

5. Mecanical and numerical models to unidimensional flexible structures / Modelos mecânicos e numéricos para estruturas flexíveis unidimensionais
Apresentamos um modelo matemático geral, baseado na teoria de Cosserat para estruturas flexíveis unidimensionais, em regime de deslocamentos finitos e sujeitas a restrições unilaterais. Ao modelo geral agregamos a hipótese de inextensibilidade e, desprezando os efeitos do cisalhamento e das forças inerciais, formulamos o problema variacionalmente tanto

6. Contact with friction using the augmented Lagrangian Method: a conditional constrained minimization problem
This work presents a formulation of the contact with friction between elastic bodies. This is a non linear problem due to unilateral constraints (inter-penetration of bodies) and friction. The solution of this problem can be found using optimization concepts, modelling the problem as a constrained minimization problem. The Finite Element Method is used to co

7. Fluxo de potencia otimo parametrico
The aim of this work is to present a parametric method for the resolution of the Optimal Power Flow (OPF) problem applied to large scale power systems. This research work on parametric optimization applied to OPF was developed at UNICAMP and at McGiII University, in Montreal, Canada. The parametric approach consists of relaxing the original problem (OPF) by

8. Metodos de solução do fluxo de potencia otimo reativo e tratamento das restrições de desigualdade
The Reactive Optimal Power Flow (ROPF) is a computational optimization tool that dispatches all reactive power sources of an electrical power system. It is extremely important in power system planning, operation and voltage collapse simulation. Its mathematical modeling involves nonlinear nonconvex equality constraints and linear and nonlinear nonconvex ineq

9. Restrições funcionais de desigualdade no FPO Newton tratadas pelo metodo da continuação
One of the best algorithms to solve the Optimal Power Flow (OPF) problem is Newton s method applied to calculate the stationary point of a quadratic approximation to the Lagrangian function, which represents the Kunh- Tucker s first order conditions. Equality constraints are included through Lagrange multipliers, while inequality constraints on variables are

10. Otimização de malhas de elementos finitos pelo metodo da recolocação dos nos na elasticidade linear
An r-method (nodal relocation method) to optimize finite element meshes in linear elasticity problems is presented in this work. The r-method consists in obtaining an adjusted position of the mesh nodes, in order to find better results related to the discretization errors. The method is viewed here as a resolution scheme of an optimization problem, where the
