Some Characteristic Quantities Associated with Homogeneous P-Type and M-Type Functions [PDF]

Journal of Inequalities and Applications, 2007
Several characteristic quantities associated with homogeneous P-type and M-type functions are introduced and studied in this paper. Further, the concepts of P-property and M-property for a couple of functions are introduced and some quantities for a pair

A study of effects of H–H quartic auto catalytic reaction with equal diffusivity in the swirling flow exterior to a rotating cylinder

International Journal of Thermofluids, 2023
In this study, we investigate the influence of quartic auto catalysis with equal diffusivity in the flow past a rotating cylinder. The flow-thermal fields are modeled using partial differential equations (PDEs), assuming a homogeneous–heterogeneous ...

Altered regional homogeneity and its association with cognitive function in adolescents with borderline personality disorder

Journal of Psychiatry and Neuroscience, 2023
Background: Adolescents with borderline personality disorder often have cognitive impairment, but the underlying mechanism for this is not clear. This study was aimed at assessing alterations in regional homogeneity using resting-state functional MRI (fMRI) in adolescents with borderline personality disorder, and evaluating the associations between ...

A Boundary Shape Function Method for Computing Eigenvalues and Eigenfunctions of Sturm–Liouville Problems

Mathematics, 2022
In the paper, we transform the general Sturm–Liouville problem (SLP) into two canonical forms: one with the homogeneous Dirichlet boundary conditions and another with the homogeneous Neumann boundary conditions.

Stability of Heterogeneous Beams with Three Supports—Solutions Using Integral Equations

Applied Mechanics, 2023
It is our main objective to find the critical load for three beams with cross sectional heterogeneity. Each beam has three supports, of which the intermediate one is a spring support.
