Generalized Fourier-Laplace Transform and Differential Equations [PDF]

open access: yes, 2015
Integral transformations are very important tool for solving various problems in mathematics, physics and engineering. Fourier and Laplace transforms are powerful tools for image processing and signal processing. However we have combined these transforms

Fluids under High Pressure Insighted by Operando Neutron Imaging and Molecular Dynamics Simulations

open access: yesAdvanced Physics Research, EarlyView.
There is limited research on how fluids behave under the extreme conditions found in fuel gas systems (high pressure) and catalytic reactors (high temperature and pressure). Neutron Imaging provides experimental data on interfacial tension, and Henry's law volatility constant, apparent molar volume, and diffusion coefficient for systems from toluene ...

A modified Laplace transform for certain generalized fractional operators [PDF]

open access: yesResults in Nonlinear Analysis, 2018
It is known that Laplace transform converges for functions of exponential order. In order to extend the possibility of working in a large class of functions, we present a modified Laplace transform that we call ρ-Laplace transform, study its properties

The growth and approximation for an analytic function represented by Laplace–Stieltjes transforms with generalized order converging in the half plane

open access: yesJournal of Inequalities and Applications, 2018
By utilizing the concept of generalized order, we investigate the growth of Laplace–Stieltjes transform converging in the half plane and obtain one equivalence theorem concerning the generalized order of Laplace–Stieltjes transforms.

Finite time ruin probabilities with one Laplace inversion. [PDF]

open access: yes
In this work we present an explicit formula for the Laplace transform in time of the finite time ruin probabilities of a classical Levy model with phase-type claims. Our result generalizes the ultimate ruin probability formula of Asmussen and Rolski [IME

Advanced Mathematical Extensions of Data Field Theory: Hyperbolic Geometry, Gauge Theory, and Higher Structures

open access: yesAdvanced Physics Research, EarlyView.
This graphical abstract illustrates the unified framework of Data Field Theory (DFT), integrating hyperbolic geometry for hierarchical embedding, gauge theory for internal symmetries, renormalization group for multi‐scale dynamics, Lévy processes for heavy‐tailed fluctuations, noncommutative geometry for quantum‐inspired cognition, and higher ...

Efficient pricing options under regime switching [PDF]

open access: yes
In the paper, we propose two new efficient methods for pricing barrier option in wide classes of Lévy processes with/without regime switching. Both methods are based on the numerical Laplace transform inversion formulae and the Fast Wiener-Hopf ...

On structural controllability in complex networks with periodic switching topologies

open access: yesAsian Journal of Control, EarlyView.
Abstract This paper investigates the structural controllability of complex networks with periodic switching topologies. First, several graph transformations that preserve structural controllability are demonstrated. Based on the n‐walk theory, a criterion is derived that determines structural controllability by analyzing only the joint graph within a ...

Calculating multivariate ruin probabilities via Gaver–Stehfest inversion technique. [PDF]

open access: yes
Multivariate characteristics of risk processes are of high interest to academic actuaries. In such models, the probability of ruin is obtained not only by considering initial reserves u but also the severity of ruin y and the surplus before ruin x.

Electrospun Porous Materials for the Next‐Generation Proton Exchange Membrane Fuel Cells: Progress, Challenges, and AI‐Optimized Perspectives

open access: yesCarbon Energy, EarlyView.
Incorporating AI to optimize solution, process, and environment enables efficient prediction of structural properties and performance, allowing tailoring of GDL, CL, and PEM fabrication to guide PEMFC toward 9.0 kW L‒1 by 2040. ABSTRACT The performance and commercial viability of proton exchange membrane fuel cells (PEMFCs) are constrained by key ...
