A Class of Extremal Functions and Trigonometric Polynomials

, 1997
In this paper we present two classes of extremal approximating functions. These functions have the property that they are entire, have finite exponential type, and provide excellent approximations along the real line for a specific set of functions.

A Random Forest–Based Global Gridded Model for Vertical Correction of Precipitable Water Vapor Accounting for Nonlinear Vertical Variation

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Vertical correction of precipitable water vapor (PWV) is a critical step in PWV fusion and atmospheric research. To address the limited accuracy of traditional global‐scale PWV vertical correction models that do not explicitly account for nonlinear vertical variations, we developed RF‐PWV, a global 1° × 1° PWV vertical correction model based ...

Mixed collocation methods for y” = f(x , y) [PDF]

, 1999
The second-order initial value problem y" = f(x,y), y(x(_0)) = y(_0), y'(x(_0)) = z(_0) which does not contain the first derivative explicitly and where the solution is oscillatory has been of great interest for many years.

Refinements of some classical inequalities involving sinc and hyperbolic sinc functions [PDF]

, 2022
Several bounds of trigonometric-exponential and hyperbolic-exponential type for sinc and hyperbolic sinc functions are presented. In an attempt to generalize the results, some known inequalities are sharpened and extended.

Some New Simple Inequalities Involving Exponential, Trigonometric and Hyperbolic Functions

, 2018
The prime goal of this paper is to establish sharp lower and upper bounds for useful functions such as the exponential functions, with a focus on exp(−x^2), the trigonometric functions (cosine and sine) and the hyperbolic functions (cosine and sine). The

Exact traveling wave solutions to the (3+1)-dimensional mKdV–ZK and the (2+1)-dimensional Burgers equations via exp(−Φ(η))-expansion method

Alexandria Engineering Journal, 2015
In this work, the exact traveling wave solutions to the (3+1)-dimensional mKdV–ZK equation and the (2+1)-dimensional Burgers equation are studied using the exp(-Φ(η))-expansion method.
