From minimal gravity to open intersection theory [PDF]

open access: yes, 2019
We investigated the relation between the two-dimensional minimal gravity (Lee-Yang series) with boundaries and open intersection theory. It is noted that the minimal gravity with boundaries is defined in terms of boundary cosmological constant $\mu_B ...

Frequency Response Analysis of Buck-Boost Inverter

open access: yesMìkrosistemi, Elektronìka ta Akustika, 2019
The paper deals with processes analysis in inverter circuits. These processes are described by differential equations with periodical coefficients. Since control signals and voltages operating in an inverter circuit are independent theirs frequencies are

Memory-Dependent-Derivatives (MDD) for magneto-thermal-plasma semiconductor medium induced by laser pulses with hyperbolic two temperature theory

open access: yesAlexandria Engineering Journal, 2022
A theoretical novel model of generalized photo-thermoelasticity and hyperbolic two-temperature theory is studied in this paper. The elastic medium is excited by an external magnetic field and pulsed laser based. The model is established in the context of

Coupling iterated Kolmogorov diffusions [PDF]

open access: yes, 2004
The Kolmogorov (1934) diffusion is the two-dimensional diffusion generated by real Brownian motion B and its time integral integral B d t. In this paper we construct successful co-adapted couplings for iterated Kolmogorov diffusions defined by adding ...

Combination of Laplace transform and residual power series techniques to solve autonomous n-dimensional fractional nonlinear systems

open access: yesNonlinear Engineering, 2021
In this work, a new iterative algorithm is presented to solve autonomous n-dimensional fractional nonlinear systems analytically. The suggested scheme is combination of two methods; the Laplace transform and the residual power series.

Different Numerical Inversion Algorithms of the Laplace Transform for the Solution of the Advection-Diffusion Equation with Non-local Closure in Air Pollution Modeling

open access: yesTrends in Computational and Applied Mathematics, 2018
In this paper, a three-dimensional solution of the steady-state advection-diffusion equation is obtained applying the Generalized Integral Advection Diffusion Multilayer Technique (GIADMT), considering non-local closure for turbulent flow. Two different

A modal approach for the solution of the non-linear induction problem in ferromagnetic media

open access: yes, 2016
The non-linear induction problem in ferromagnetic media is solved using the fixed-point iteration method, where the linearized problem at each iteration is treated by means of a modal approach.

On algebraic damping close to inhomogeneous Vlasov equilibria in multi-dimensional spaces [PDF]

open access: yes, 2012
We investigate the asymptotic damping of a perturbation around inhomogeneous stable stationary states of the Vlasov equation in spatially multi-dimensional systems.

Photo-Thermo-Mechanical-Elastic interactions due to Hall current in functionally graded (FG) semiconductor excited medium with hyperbolic Two-Temperature

open access: yesAlexandria Engineering Journal, 2022
A theoretical novel model in the context of the photo-thermoelasticity theory is examined. The novel mode is studied under the impact of the external magnetic field with strong intensity.

On the One dimensional Poisson Random Geometric Graph [PDF]

open access: yes, 2010
Given a Poisson process on a bounded interval, its random geometric graph is the graph whose vertices are the points of the Poisson process and edges exist between two points if and only if their distance is less than a fixed given threshold.
