The covariogram and Fourier–Laplace transform in ℂⁿ [PDF]

Proceedings of the London Mathematical Society, 2016
The covariogram g K of a convex body K in R n is the function which associates to each x ∈ R n the volume of the intersection of K with K + x. Determining K from the knowledge of g K is known as the Covariogram Problem. It is equivalent to determining the characteristic function 1 K of K from the modulus of its Fourier transform 1 K in R n , a ...

New Integral Transform: Shehu Transform a Generalization of Sumudu and Laplace Transform for Solving Differential Equations

International Journal of Analysis and Applications, 2019
In this paper, we introduce a Laplace-type integral transform called the Shehu transform which is a generalization of the Laplace and the Sumudu integral transforms for solving differential equations in the time domain. The proposed integral transform is

Fourier-Laplace Transform and Isomonodromic Deformations

Funkcialaj Ekvacioj, 2016
Using the Fourier-Laplace transform, we describe the isomonodromy equations for meromorphic connections on the Riemann sphere with unramified irregular singularities as those for connections with a (possibly ramified) irregular singularity and a regular singularity. This generalizes some results of Harnad and Woodhouse.

The Fourier, Laplace Transformations and the Newton Potential [PDF]

American Journal of Applied Mathematics and Statistics, 2014
With help of a methods of Fourier`s analysis we consider the analytic continuation of Laplace transformation (with help a values on the complex axis) to the left part of plane, when the continuation is odd ore even.

Application of Generalized Fractional Thermoelasticity Theory with Two Relaxation Times to an Electromagnetothermoelastic Thick Plate

Advances in Materials Science and Engineering, 2016
The fractional mathematical model of Maxwell’s equations in an electromagnetic field and the fractional generalized thermoelastic theory associated with two relaxation times are applied to a 1D problem for a thick plate. Laplace transform is used.

Upcycling Keratin‐Based Textile Waste Into High‐Performance Hybrid Fibers Via Tuning the Interfacial Interactions

Advanced Functional Materials, EarlyView.
Keratin recovered from animal‐hair textile waste is fractionated and blended with cellulose to produce continuously spun hybrid fibers. Selecting the high‐molecular‐weight keratin fraction enables 30 wt.% keratin incorporation while maintaining high strength in dry and wet states.
