Computational study of permeability in cardboard coating layers
Abstract We develop a virtual material structure model based on a combination of tessellations and Gaussian random fields for a coating layer of paperboard used for packaging and designed to facilitate printing on the surface. To fit the model to tomographic image data acquired using combined focused ion beam and scanning electron microscopy (FIB‐SEM),

Behavior of Bessel functions in neuron with multi-dendrites
This study investigates the integration of Bessel functions as activation functions within multi-dendritic neurons, aiming to address the limitations of traditional activation functions, such as sigmoid and ReLU.

Generating Functions for Bessel Functions [PDF]
On replacing the parameter n in Bessel's differential equation1.1by the operator y(∂/∂y), the partial differential equation Lu = 0 is constructed, where1.2This operator annuls u(x, y) = v(x)yn if, and only if, v(x) satisfies (1.1) and hence is a cylindrical function of order n.

The Schrödinger Equation for a Free Particle: Generalized Bessel Solutions
We demonstrate the time evolution of a free particle in a three-dimensional space given that the initial condition is any arbitrary radial function f(r).

Relation of Some Known Functions in terms of Generalized Meijer G-Functions
The aim of this paper is to prove some identities in the form of generalized Meijer G-function. We prove the relation of some known functions such as exponential functions, sine and cosine functions, product of exponential and trigonometric functions ...
