A primal–dual penalty-interior-point method for solving the reactive optimal power flow problem with discrete control variables
(2022-06-01)
The Optimal Reactive Power Flow (ORPF) problem has been used as an important computational tool for power system planning and operation. Its mixed-discrete version (DORPF) is formulated as a non-convex, non-linear optimization ...
Numerical assessment of mass conservation on a MAC-type method for viscoelastic free surface flows
(2012-12-01)
A numerical study of mass conservation of MAC-type methods is presented, for viscoelastic free-surface flows. We use an implicit formulation which allows for greater time steps, and therefore time marching schemes for ...
Flammability limits temperature dependence of pure compounds in air at atmospheric pressure
(2017-01-01)
The objective of the present work is to study the temperature dependence of the flammability limits for pure compounds, and to develop a methodology to determine these limits in air at atmospheric pressure and at different ...
Interlaboratory validation of modified classical qualitative methods for detection of adulterants in milk: starch, chloride and sucrose

Comparison of GWA statistical methods for traits under different genetic structures: A simulation study
(2020-11-01)
Several methods have been used to perform genome wide association (GWA) studies, aiming to map quantitative trait loci (QTL) and candidate variants. The single-step genomic best linear unbiased prediction (ssGBLUP) method ...
Comparison between the complete Bayesian method and empirical Bayesian method for ARCH models using Brazilian financial time series
(Sociedade Brasileira de Pesquisa Operacional, 2012)
In this work we compared the estimates of the parameters of ARCH models using a complete Bayesian method and an empirical Bayesian method in which we adopted a non-informative prior distribution and informative prior ...
Numerical methods for elliptic partial differential equations with rapidly oscillating coefficients
(2003)
This paper presents two methods for the numerical solution of the classical homogenization problem of elliptic
operators with periodically oscillating coefficients. The numerical solution of such problems is difficult ...
Synthesis and characterization of lead zirconate titanate (PZT) obtained by two chemical methods
(2013-08-05)
Lead zirconate titanate (PZT) was synthesized at the ratio of Zr/Ti=52/48 using two synthesis methods: the polymeric precursor method (PPM) and the microwave-assisted hydrothermal method (MAHM). The synthesized materials ...
