Uma demonstração do teorema fundamental da álgebra
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em Matemática (PROFMAT)Câmpus São Carlos, 2016-10-21)
In this work we explain an elegant and accessible proof of the Fundamental Theorem of Algebra using the Lagrange Multipliers method. We believe this will be a valuable resource not only to Mathematics students, but also ...
Existence and approximation for variational problems under uniform constraints on the gradient by power penalty
(SIAM Publications, 2015)
Variational problems under uniform quasi-convex constraints on the gradient are studied. Our technique consists in approximating the original problem by a one-parameter family of smooth unconstrained optimization problems. ...
Influence of the Operational Constraints in the Active Transmission Losses Allocation via Lagrange Multipliers
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
This paper presents an approach for the active transmission losses allocation between the agents of the system. The approach uses the primal and dual variable information of the Optimal Power Flow in the losses allocation ...
An analytical solution to the optimal power flow
This letter presents an approach for a geometrical solution of an optimal power flow (OPF) problem for a two-bus system (slack and PV busses). The algebraic equations for the calculation of the Lagrange multipliers and for ...
