Utilização de índices de estabilidade transitória para a avaliação de segurança dinâmica
(2003-12-01)
Indices that report how much a contingency is stable or unstable in an electrical power system have been the object of several studies in the last decades. In some approaches, indices are obtained from time-domain simulation; ...
Leis de escala e transientes no mapa logistic-like perturbado
(Universidade Estadual Paulista (Unesp), 2020-07-29)
Nesta dissertação consideramos o mapa logistic-like com parâmetro de controle perturbado por uma pequena função periódica. Fazendo uma escolha apropriada de alguns parâmetros podemos recuperar mapeamentos diferentes ...
Leak detection by inverse transient analysis in an experimental PVC pipe system
(IWA PUBLISHING, 2011)
Leakage reduction in water supply systems and distribution networks has been an increasingly important issue in the water industry since leaks and ruptures result in major physical and economic losses. Hydraulic transient ...
Transient effectiveness factor in porous catalyst particles. Application to kinetic studies with batch reactors
(Institution of Chemical Engineers, 2017-02)
The actual transient characteristics of the effectiveness factor for reactions in porous catalyst particles were considered in a model for kinetic studies in gradientless batch reactors. The transient effectiveness factor ...
