24-Pulse active front end rectifier with low switching frequency
(2004)
High-power medium voltage converters face the issues of the network interaction, reliability and efficiency. In addition, 4-quadrant operation is needed for FACTS, distributed generation and regenerative drive systems. ...
Influence of nonsphericity of planetary satellites and perturbation of the third-body on the artificial satellites motion
(2011-12-01)
Some orbital characteristics of lunar artificial satellites is presented taking into account the perturbation of the third-body in elliptical orbit and the non-uniform distribution of mass of the Moon. We consider the ...

Harmonic response of a class of finite extensibility nonlinear oscillators
(IOP Publishing, 2011-06)
Finite extensibility oscillators are widely used to simulate those systems which can not be extended to infinity. For example, they are used when modelling the bonds between molecules in a polymer or DNA molecule or when ...
