On energy pumping, synchronization and beat phenomenon in a nonideal structure coupled to an essentially nonlinear oscillator
(Springer, 2009-04-01)
In this paper, we dealt with energy pumping, synchronization, and beat phenomenon in transients and steady-state vibrations (in a non-ideal structure (NIS)) having an attachment, coupled to an oscillator containing essential ...

Pumped hydro storage plants: a review
(2020-08-01)
Pumped hydro storage plants (PHSP) are considered the most mature large-scale energy storage technology. Although Brazil stands out worldwide in terms of hydroelectric power generation, the use of PHSP in the country is ...
Thermal analysis of solar‑assisted heat pumps for swimming pool heating
(Springer, 2017-06)
The present work analyzes the technical feasibility of solar-assisted heat pumps for swimming pool heating in South Brazil. The methodology is based on computer simulations for four configurations of heating systems for ...
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 ...

Dynamics of energy transfer and frequency upconversion in Tm3+ doped fluoroindate glass
(2004-09-01)
The spectroscopic properties of Tm3+-doped fluoroindate glasses (FIG) were described by single wavelength pumping in the red region. The Judd-Ofelt (J-O) theory was used to obtain the quantum efficiency of the 4f-4f ...
