An alternative theoretical approach to describe planetary systems through a Schr€odinger-type diffusion equation
(Elsevier, 2004)
In the present work we show that planetary mean distances can be calculated with the help of a Schr€odinger-type diffusion equation. The obtained results are shown to agree with the observed orbits of all the planets and ...

Cogeneration design problem Computational complexity analysis and solution through an expert system
(Emerald Group Publishing Limited, 2014-01-01)
Purpose - The purpose of this paper is twofold: to analyze the computational complexity of the cogeneration design problem; to present an expert system to solve the proposed problem, comparing such an approach with the ...
Impactos econômicos e desempenho energético de alternativas construtivas em um projeto padrão de creche pública no clima de Natal/RN
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ARQUITETURA E URBANISMO, 2018-03-27)
It is estimated that the energy saving potential in new buildings can reach 50%
(PROCEL, 2015). Several studies carried out for the Natal-RN climate reinforce this
trend and have demonstrated a vast potential for reducing ...
Pseudoinvariance and the extra degree of freedom in f (T) gravity
(American Physical Society, 2020-04)
Nonlinear generalizations of teleparallel gravity entail the modification of a Lagrangian that is pseudoinvariant under local Lorentz transformations of the tetrad field. This procedure consequently leads to the loss of ...
High frequency solutions for the singularly-perturbed one-dimensional nonlinear Schrodinger equation
(SPRINGER, 2006-10)
This article is devoted to the nonlinear Schrodinger equation
epsilon(2)u'' - V(x)u + vertical bar u vertical bar(p-1)u = 0,
when the parameter epsilon approaches zero. All possible asymptotic behaviors of bounded ...
BIOSORPTION STUDY OF Ni2+ AND Cr3+ BY Sargassum filipendula: KINETICS AND EQUILIBRIUM
(Brazilian Soc Chemical EngSao PauloBrasil, 2014)
Some nonlinear mechanical problems solved with analytical solutions
(Planta Piloto de Ingeniería Química, 2004-04)
In this paper the analytical solution of nonlinear ordinary differential systems is addressed. Some of the problems are classical in the related literature and exhibit chaotic behavior in certain ranges of the involved ...
Kinematic and spermatic recovery after selection by centrifugation in colloid solutions of ovine cryopreserved semen
(2016-01-01)
Frozen and thawed ovine semen undergo morphological and functional changes that prevent or decrease the efficiency of fertilization. Sperm selection methods seek to improve the quality and viability of the fertilizing ...
