Logarithmic barrier-augmented Lagrangian function to the optimal power flow problem
(Elsevier B.V., 2005-09-01)
This paper presents a new approach to solve the Optimal Power Flow problem. This approach considers the application of logarithmic barrier method to voltage magnitude and tap-changing transformer variables and the other ...
Primal-dual logarithmic barrier and augmented Lagrangian function to the loss minimization in power systems
(Taylor & Francis Inc, 2006-07-01)
This article presents a new approach to minimize the losses in electrical power systems. This approach considers the application of the primal-dual logarithmic barrier method to voltage magnitude and tap-changing transformer ...
A modified Primal-Dual Logarithmic-Barrier Method for solving the Optimal Power Flow problem with discrete and continuous control variables
(Elsevier B.V., 2012-11-01)
The aim of solving the Optimal Power Flow problem is to determine the optimal state of an electric power transmission system, that is, the voltage magnitude and phase angles and the tap ratios of the transformers that ...
A resolução do problema de despacho ótimo de reativos pelo método da função Lagrangiana-barreira relaxada
(2008-05-01)
This work presents the application of the relaxed barrier-Lagrangian function method to the optimal reactive dispatch problem, which is a nonlinear nonconvex and large problem. In this approach the inequality constraints ...
Um método primal-dual aplicado na resolução do problema de fluxo de potência ótimo
(Sociedade Brasileira de Pesquisa Operacional, 2004-08-01)
Este artigo apresenta uma nova abordagem para a resolução do problema de Fluxo de Potência Ótimo. Nesta abordagem as restrições canalizadas são tratadas pelo método de barreira logarítmica. Uma função Lagrangiana aumentada ...
Eletroforese em papel das proteínas do líquido cefalorraqueano e seu valor prático em clínica neurológica
(Academia Brasileira de Neurologia - ABNEURO, 1964-03-01)
This paper is based on the study of the protein profile of the cerebrospinal fluid of 300 neurological patients. This material was analysed in the same way as that one performed by Matiar and Schmidt (1958) and it was found ...
Fluxo de potência ótimo reativo via método da função lagrangiana barreira modificada
(Sociedade Brasileira de Automática, 2008-03-01)
Este artigo apresenta uma nova abordagem para a resolução do problema de Fluxo de Potência Ótimo Reativo. Nesta abordagem, as restrições de desigualdade são tratadas pela associação dos métodos de Barreira Modificada e ...
Water regulation of actinomycin-D binding to DNA: the interplay among drug affinity, DNA long-range conformation, and hydration
(Wiley-Blackwell, 2000-01-01)
Actiaomycin-D (actD) binds to natural DNA at two different classes of binding sites, weak and strong. The affinity for these sites is highly dependent on DNA se(sequence and solution conditions, and the interaction appears ...
Evaluation of oxygen absorber on antimicrobial preservation of lasagna–type fresh pasta under vacuum packed
(Ciência e Agrotecnologia, 2019)
