Conservation laws for non-potential operators
(Revista Brasileira de Ciencias Mecanicas/Journal of the Brazilian Society of Mechanical Sciences, 1999-12-01) [Artigo]
A study was developed in order to build a function M invariant in time, by means of Hamiltonian's formulation, taking into account the equation associated to the problem, showing that starting from this function the equation ...
Synchronous machines parameters identification using load rejection test data
(IEEE International Electric Machines and Drives Conference Record, IEMDC, 1997-01-01) [Trabalho apresentado em evento]
This work shows a computational methodology for the determination of synchronous machines parameters using load rejection test data. The quadrature axis parameters are obtained with a rejection under an arbitrary reference, ...
Joint economic design of X̄ and R control charts for processes subject to two independent assignable causes
(IIE Transactions (Institute of Industrial Engineers), 1993-11-01) [Artigo]
A model for the joint economic design of X̄ and R control charts is developed. This model assumes that the process is subject to two assignable causes. One assignable cause shifts the process mean; the other shifts the ...
Thermal diffusivity measurements in C2H2-plasma polymerized films using photoacoustic techniques
(Journal of Materials Science Letters, 1996-04-01) [Artigo]
Tensoes Residuais na Soldagem, Aspectos Basicos
(Revista Brasileira de Ciencias Mecanicas/Journal of the Brazilian Society of Mechanical Sciences, 1995-12-01) [Artigo]
The purpose of this paper is to analyze the basic aspects of the residual stresses in welding. Concepts about macro and micro residual stresses in metals are considered in welding. In a simple welding model is shown how ...
Towards an intelligent graphical interface for linear programming modelling
(Journal of Intelligent Systems, 1996-12-01) [Artigo]
The increase of computing power of the microcomputers has stimulated the building of direct manipulation interfaces that allow graphical representation of Linear Programming (LP) models. This work discusses the components ...
