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 ...
Comércio bilateral entre os países membros do MERCOSUL : uma visão do bloco através do modelo gravitacional
(Universidade do Vale do Rio dos Sinos, 2012-05-25)
The second wave of regionalism, occurred from the nineties, changed significantly the international trade scenario, with the creation of many Preferential Trading Arrangements (PTA). In a beginning of ...

A family of vortex rings and a variational application to potential flows around three-dimensional bodies
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2008)
A variational formulation and solution of general three-dimensional potential flows gave rise to the construction of a special family of ‘trial functions’. This family is composed by circular-sector vortex rings, here named ...
Substitution-newton-Raphson method for the solution of electric network equations
(2006-12-01)
The power flow problem, in transmission networks, has been well solved, for most cases, using Newton-Raphson method (NR) and its decoupled versions. Generally speaking, the solution of a non-linear system of equations ...
Detection of seepage paths in small earth dams using the self-potential method (SP)
(2020-07-01)
The application of geoelectric methods, such as induced polarization (IP), the electrical resistivity and the self-potential (SP), presents an important indirect study methodology in several areas of geology, such as mining, ...
Theoretical Relation Between the Tube Zeta Potential and the Background Electrolyte Composition in Capillary Electrophoresis
(Springer, 2004-08)
This work presents a theoretical analysis of the relation between the tube zeta potential and the electrolyte solution composition typically found in capillary electrophoresis. A model including the relevant physicochemical ...
Iterative solution of panel method discretizations for potential flow problems. The modal multipolar preconditioning
(John Wiley & Sons Ltd, 2000-12)
The iterative solution of linear systems arising from panel method discretization of three-dimensional (3D) exterior potential problems coming mainly from aero-hydrodynamic engineering problems, is discussed. An original ...
Roll-Waves Mathematical Model as a Risk-Assessment Tool: Case Study of Acquabona Catchment
(Asce-amer Soc Civil Engineers, 2018-12-01)
In an attempt to develop risk-assessment engineering tools, a method is presented that involves the application of a simplified model that represents periodic permanent roll waves in Herschel-Bulkley laminar fluid flows. ...
