Monotonicity and Inequalities for Ratio of the Generalized Logarithmic Means [PDF]

open access: yes, 2003
Let c > b > a > 0 be real numbers. Then the function f(r) = Lr(a,b)/Lr(a,c) is strictly decreasing on (−∞,∞), where Lr(a, b) denotes the generalized (extended) logarithmic mean of two positive numbers a and ...

Logarithmic Convexity of the One-Parameter Mean Values [PDF]

open access: yes, 2004
In this article, the logarithmic convexity of the one-parameter mean values J(r) and the monotonicity of the product J(r)J(−r) with r Є R are presented. Some more general results are established.

Blow-up for logarithmic viscoelastic equations with delay and acoustic boundary conditions

open access: yesAdvances in Nonlinear Analysis, 2023
In the present work, we establish a blow-up criterion for viscoelastic wave equations with nonlinear damping, logarithmic source, delay in the velocity, and acoustic boundary conditions.

Bias Correction in Logarithmic Regression and Comparison with Weighted Regression for Nonlinear Models [PDF]

open access: yes, 2011
Non-linear models with heteroscedasticity are commonly used in ecological and forestry modeling, and logarithmic regression and weighted regression are usually employed to estimate the parameters. Using the single-tree biomass data of three large samples,

Towards a generalised artificial neural network for sub-grid filtered density function closure in turbulent combustion

open access: yesApplications in Energy and Combustion Science, 2023
An artificial neural network (ANN) is trained on moderate or intense low-oxygen dilution (MILD) combustion to predict the sub-grid filtered density function (FDF) in large eddy simulation (LES).

Holographic correlation functions in Critical Gravity

open access: yesJournal of High Energy Physics, 2017
We compute the holographic stress tensor and the logarithmic energy-momentum tensor of Einstein-Weyl gravity at the critical point. This computation is carried out performing a holographic expansion in a bulk action supplemented by the Gauss-Bonnet term ...

General stability and exponential growth of nonlinear variable coefficient wave equation with logarithmic source and memory term [PDF]

open access: yesMathematical Methods in the Applied Sciences, 2021
This paper is concerned with the asymptotic stability and instability of solutions to a variable coefficient logarithmic wave equation with nonlinear damping and memory term. Such model describes wave traveling through nonhomogeneous viscoelastic materials.
