Linear stability of electron-flow hydrodynamics in ungated semiconductors.
(2009)
Semiconductors play an important role in modern electronic technology. They are present in most sensing and transduction applifations, satisfying requirements such as compactnes, tuanbility and portability. It is known ...
Multiarea optimal power flow using multiobjective evolutionary algorithm
(2009-12-17)
In this work the multiarea optimal power flow (OPF) problem is decoupled into areas creating a set of regional OPF subproblems. The objective is to solve the optimal dispatch of active and reactive power for a determined ...
Development of comparative electronic circuit for reduced flow valve control

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 ...

Rapid determination of zinc in foods by flow injection analysis with flame AAS using gradient calibration method
(2004-09-01)
A calibration method was developed using flow injection analysis (FI) with a Gradient Calibration Method (GCM). The method allows the rapid determination of zinc In foods (approximately 30 min) after treatment with ...
A high frequency electronic transducer for multiphase flow measurements

Development and application of wire-mesh sensors for high-speed multiphase flow imaging
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Elétrica e Informática Industrial, 2015-08-14)
Multiphase flows are present not only in nature but also are very common in industrial activities such as in exploration, production and transport of oil and gas. In oil production, the mixture of gas, oil and water is ...
