Timoshenko beam and plate non-stationary vibrations [PDF]

open access: yesINCAS Bulletin, 2021
The problems of Timoshenko beams and plates lateral vibrations under the influence of unsteady loads are considered. Both beam and plate is supposed to be unlimited. In case of the plate the problem has been simply studied.

On the Fractional Derivative Duality in Some Transforms

open access: yesMathematics, 2023
Duality is one of the most interesting properties of the Laplace and Fourier transforms associated with the integer-order derivative. Here, we will generalize it for fractional derivatives and extend the results to the Mellin, Z and discrete-time Fourier

Fourier/Laplace Transforms and Ruin Probabilities [PDF]

open access: yesASTIN Bulletin, 2002
AbstractIn this paper we use Fourier/Laplace transforms to evaluate numerically relevant probabilities in ruin theory as an application to insurance. The transform of a function is split in two: the real and the imaginary parts. We use an inversion formula based on the real part only, to get the original function.By using an appropriate algorithm to ...

The Fourier–Laplace Transformation and Material Law Operators [PDF]

open access: yes, 2021
AbstractIn this chapter we introduce the Fourier–Laplace transformation and use it to define operator-valued functions of ∂t,ν; the so-called material law operators. These operators will play a crucial role when we deal with partial differential equations.

The Generalized Fourier Transform: A Unified Framework for the Fourier, Laplace, Mellin and Z Transforms [PDF]

open access: yesIEEE Transactions on Signal Processing, 2021
<div>This paper introduces Generalized Fourier transform (GFT) that is an extension or the generalization of the Fourier transform (FT). The Unilateral Laplace transform (LT) is observed to be the special case of GFT. GFT, as proposed in this work, contributes significantly to the scholarly literature.

ABOUT THE EQUALITY OF THE TRANSFORM OF LAPLACE TO THE TRANSFORM OF FOURIER

open access: yesПроблемы анализа, 2016
We proved that the transform of Laplace does not have complex part on the complex axis for the wide class of functions in different situations. The main theorem is proved presenting a function as sum of two Laplace transforms.

Fractional Equations for the Scaling Limits of Lévy Walks with Position-Dependent Jump Distributions

open access: yesMathematics, 2023
Lévy walks represent important modeling tools for a variety of real-life processes. Their natural scaling limits are known to be described by the so-called material fractional derivatives.
