The rise of new dc technologies is pushing the development of highly efficient dc-dc converters, especially at high voltage and high step ratio. Modular multilevel converters (MMCs) are an attractive alternative because ...

Neste trabaho realizamos um estudo detalhado do posicionamento dos zeros de Yang- Lee do modelo de Blume-Emery-Griffiths unidimensional atraves de metodos analiticos e numericos. Em particular, analisamos o efeito de uma ...

In [Molaie et al., 2013] the authors provided the expressions of 23 quadratic differential systems in R3 with the unusual feature of having chaotic dynamics coexisting with one stable equilibrium point. In this paper, we ...

The standard way of evaluating residues and some real integrals through the residue theorem (Cauchy's theorem) is well-known and widely applied in many branches of Physics. Herein we present an alternative technique based ...
