Modelling line edge roughness in periodic line-space structures by Fourier optics to improve scatterometry [PDF]

Journal of the European Optical Society-Rapid Publications, 2014
In the present paper, we propose a 2D-Fourier transform method as a simple and efficient algorithm for stochastical and numerical studies to investigate the systematic impacts of line edge roughness on light diffraction pattern of periodic line-space ...

On Local Unique Solvability for a Class of Nonlinear Identification Problems

Axioms, 2023
Nonlinear identification problems for evolution differential equations, solved with respect to the highest-order Dzhrbashyan–Nersesyan fractional derivative, are studied.

Disentangling the Information in Species Interaction Networks

Entropy, 2021
Shannon’s entropy measure is a popular means for quantifying ecological diversity. We explore how one can use information-theoretic measures (that are often called indices in ecology) on joint ensembles to study the diversity of species interaction ...

Analytic Resolving Families for Equations with the Dzhrbashyan–Nersesyan Fractional Derivative

Fractal and Fractional, 2022
In this paper, a criterion for generating an analytic family of operators, which resolves a linear equation solved with respect to the Dzhrbashyan–Nersesyan fractional derivative, via a linear closed operator is obtained.

On Local Time for Telegraph Processes

Mathematics, 2023
The article consists of an introduction into the theory of passage times associated with telegraph processes. Local time for the telegraph process is defined and analysed. We provide some limited results for telegraphic local times.

Modelling car-following dynamics with stochastic input-state-output port-Hamiltonian systems [PDF]

EPJ Web of Conferences
In this contribution, we introduce a general class of car-following models with an input-state-output port-Hamiltonian structure. We derive stability conditions and long-term behavior of the finite system with periodic boundaries and quadratic ...
