Is (Independent) Subordination Relevant in Equity Derivatives?
Applied Stochastic Models in Business and Industry, EarlyView.ABSTRACT Monroe (1978) demonstrates that any local semimartingale can be represented as a time‐changed Brownian Motion (BM). A natural question arises: does this representation theorem hold when the BM and the time‐change are independent? We prove that a local semimartingale is not equivalent to a BM with a time‐change that is independent from the BM ...

A Laplace Transform Method for the Image In-Painting
Journal of Algorithms & Computational Technology, 2015 There are many image processing techniques based on partial differential equations that perform well, but they consume much computational time. It's vital that rapid and efficient ways of solving these equations are developed.

Batteries &Supercaps, EarlyView.Commercial cells made of four different cathode materials are studied for two modes of degradation and subsequently characterized with three different diagnostic techniques during and after aging, leading to a total of more than 200 cells analyzed for this study. Thus, this study reveals aging effects for lithium–ion batteries beyond state of health of

Investigation of continuous-time quantum walks via spectral analysis and Laplace transform [PDF]
arXiv, 2007 Continuous-time quantum walk (CTQW) on a given graph is investigated by using the techniques of the spectral analysis and inverse Laplace transform of the Stieltjes function (Stieltjes transform of the spectral distribution) associated with the graph.

Regularization of the inverse Laplace transform by mollification
Inverse ProblemsAbstract In this paper we study the inverse Laplace transform. We first derive a new global logarithmic stability estimate that shows that the inversion is severely ill-posed. Then we propose a regularization method to compute the inverse Laplace transform using the concept of mollification.

Bending of a Viscoelastic Timoshenko Cracked Beam Based on Equivalent Viscoelastic Spring Models
Advances in Civil Engineering, 2021 Considering the transverse crack as a massless viscoelastic rotational spring, the equivalent stiffness of the viscoelastic cracked beam is derived by Laplace transform and the generalized Dirac delta function.
