Some properties of solutions of the homogeneous nonlinear second order differential equations

6 years ago

Abstract In this paper we consider the following nonlinear homogeneous second order differential equations, \(F(x,y,y^{\prime},y^{\prime\prime})=0.\) We present for the solutions,…

Convergence results for contact problems with memory term

6 years ago

AbstractIn this paper, we consider two quasistatic contact problems. The material’s behavior is modelled with an elastic constitutive law for…

Conjugate free convection in a vertical channel filled with nanofluid

6 years ago

AbstractThe steady natural conjugate convection in a long vertical channel filled with a nanofluid and including internal heat generation is…

Detection of low level periodic signals through enhanced self-correlation method. The case of ER Vulpeculae

6 years ago

AbstractThe self-correlation (SC) method proposed three decades ago by Percy, Jakate and Matthews is a complementary time series analysis method…

Laguerre collocation solutions vs. analytic results for singular semilinear BVPs on the half line

6 years ago

AbstractWe make use of two Laguerre collocation techniques as a way to illustrate, deepen or extend some analytic results of…

Pseudospectral solutions to some singular nonlinear BVPs. Applications in nonlinear mechanics

7 years ago

AbstractWe solve by Laguerre collocation method two second order genuinely nonlinear singularly perturbed boundary value problems and a fourth order…

Spectral collocation for multiparameter eigenvalue problems arising from separable boundary value problems

7 years ago

AbstractIn numerous science and engineering applications a partial differential equation has to be solved on some fairly regular domain that…

Solute transport in aquifers with evolving scale heterogeneity

7 years ago

AbstractTransport processes in groundwater systems with spatially heterogeneous properties often exhibit anomalous behavior. Using first-order approximations in velocity fluctuations we…

Consistency issues in PDF methods

7 years ago

AbstractConcentrations of chemical species transported in random environments need to be statistically characterized by probability density functions (PDF). Solutions to evolution equations…

A Fokker-Planck approach for probability distributions of species concentrations transported in heterogeneous media
