On energy transfer between vibrating systems under linear and nonlinear interactions
(Springer, 2009-07-01)
The present study deals with energy transfer in a dissipative mechanical system. Numerical results are given by considering two different potentials and periodical excitation. Specifically, we show energy transfer from ...

Optimal linear control driven for piezoelectric non-linear energy harvesting on non-ideal excitation sourced
(2014-01-01)
Non-linear energy harvesting system was project to enhance interaction to ambient vibration that is wide band and low power which difficult the design for resonant solution. To improve efficiency of a non-linear design it ...
Ghost Dark Energy Model with Non-linear Interaction
(2018-07-23)
In this paper we study a dark energy model taking into account a non-linear
interaction between the dark energy and dark matter components. The non-linear
interaction term, used in this work, is proportional to the square ...
Linear and nonlinear interactions in the dark sector
(American Physical Society, 2010-02)
We investigate models of interacting dark matter and dark energy for the Universe in a spatially flat Friedmann-Robertson-Walker space-time. We find the "source equation" for the total energy density and determine the ...
Dark matter, dark energy, and dark radiation coupled with a transversal interaction
(American Physical Society, 2012-11)
We investigate a cosmological scenario with three interacting components that includes dark matter, dark energy, and radiation in the spatially flat Friedmann-Robertson-Walker universe. We introduce a 3-dimensional internal ...
Asymptotic approach for the nonlinear equatorial long wave interactions
(2011-08-30)
In the present work we use an asymptotic approach to obtain the long wave equations. The shallow water equation is put as a function of an external parameter that is a measure of both the spatial scales anisotropy and the ...

Dark matter interacts with variable vacuum energy
(Springer, 2014-08)
We investigate a spatially flat Friedmann-Robertson-Walker (FRW) scenario with two interacting components, dark matter and variable vacuum energy (VVE) densities, plus two decoupled components, one is a baryon term while ...
