On the Superstability of the Pexider Type Trigonometric Functional Equation

open access: yesJournal of Inequalities and Applications, 2010
We will investigate the superstability of the (hyperbolic) trigonometric functional equation from the following functional equations: f(x+y)±g(x−y)=λf(x)g(y) andf(x+y)±g(x−y)=λg(x)f(y), which can be considered ...

Ambiguity function and accuracy of the hyperbolic chirp: comparison with the linear chirp [PDF]

open access: yes, 2017
In this paper, we derive the Ambiguity Function (AF) of a narrowband and a wideband hyperbolic chirp. We calculate the second derivatives of the squared amplitude of the narrowband Complex Ambiguity Function (CAF) and use them to calculate the Fisher ...

Numerically Stable form of Green’s Function for a Free-Free Uniform Timoshenko Beam

open access: yesMathematics, 2022
Beam models are widely applied in civil engineering, transport, and industry because the beams are basic structural elements. When dealing with the high-order modes of beam in the context of applying the modal analysis method, the numerical instability ...

Reiber’s Diagram for Kappa Free Light Chains: The New Standard for Assessing Intrathecal Synthesis?

open access: yesDiagnostics, 2019
Oligoclonal bands are the gold standard for determination of an intrathecal immunoglobulin G synthesis and were recently included in the McDonald criteria of 2017 to diagnose relapsing multiple sclerosis (MS) as a substitute for dissemination in time ...

Properties of generalized univariate hypergeometric functions [PDF]

open access: yes, 2006
Based on Spiridonov's analysis of elliptic generalizations of the Gauss hypergeometric function, we develop a common framework for 7-parameter families of generalized elliptic, hyperbolic and trigonometric univariate hypergeometric functions.

On a more accurate half-discrete Hilbert-type inequality involving hyperbolic functions

open access: yesOpen Mathematics, 2022
In this work, by the introduction of a new kernel function composed of exponent functions with several parameters, and using the method of weight coefficient, Hermite-Hadamard’s inequality, and some other techniques of real analysis, a more accurate half-
