Bayesian inference of fractional brownian motion of multivariate stochastic differential equations
(Semnan University, 20220101)There have been much interest in analysis of stochastic differential equation with long memory, represented by fractional diffusion process, this property have been proved itself in financial mathematic as intrinsic ...

Bayesian parameter estimation in addiction model
(Semnan University, 20220101)In this paper, we investigated the performance of Bayesian Computational methods for estimating the parameters of the multinomial Logistic regression model. We discussed two of the most common Bayesian computational ...

Bifurcation analysis and chaos control of the population model with harvest
(Semnan University, 20220101)In this article, we investigated the dynamic behavior of a discretetime population model with the harvest. We give numerical simulation and chaos control by using the linear feedback control method.

The bifurcation analysis of an ecotoxicant model with antipredator behavior
(Semnan University, 20220101)In this study, the mathematical model of four differential equations for organisms that describe the effect of antipredation behavior, age stage and toxicity have been analyzed. Local bifurcation and Hopf bifurcation have ...

The bifurcation analysis of an ecological model involving SIS disease with a prey refuge
(Semnan University, 20220101)This paper deals with an epidemiological system with stagestructured, harvesting and refuge for only prey, the disease of type (SIS) is just in the immature of the prey. The sufficient conditions guaranteeing the occurrence ...

The bifurcation analysis of an epidemiological model involving two diseases in predator
(Semnan University, 20220101)In this paper, the local bifurcation conditions that occur near each of the equilibrium points of the ecoepidemiological system of one prey population apparition with two diseases in the same population of predator have ...

The bifurcation diagram of an elliptic $P$Kirchhofftype problem with respect to the stiffness of the material
(Semnan University, 20220101)We study a superlinear and subcritical $p$Kirchhofftype problem which is variational and depends upon a real parameter $\lambda$. The nonlocal term forces some of the fiber maps associated with the energy functional to ...

Blow up of solutions for a r(x)Laplacian Lam'{e} equation with variableexponent nonlinearities and arbitrary initial energy level

Boundedness of a new kind of Toeplitz operator on $2\pi$periodic holomorphic functions on the upper halfplane
(Semnan University, 20220101)In the present paper, We introduce a new kind of Toeplitz operators on the spaces of $2\pi$ periodic holomorphic functions on the upper halfplane equipped with an integral norm similar to the norm of $L^{p}$ spaces. We ...

A call reservation scheme for channel allocation using predication approach (CAPA) in wireless networks
(Semnan University, 20220101)The uncommitted bandwidth of the spectrum must be expeditiously employed by the mobile users, since nowadays the mobile users are rising step by step. The major aim of the channel reservation process is to minimize the ...

Caputo definition for finding fractional moments of power law distribution functions
(Semnan University, 20220101)In this paper, we propose a modern technique to derive fractional moment by using Caputo definition of fractional derivative. Such technique represents a modification of fractional moments on a certain type of function ...

CFD Analysis of piston bowls geometry for CI direct injection engine using finite element analysis
(Semnan University, 20220101)Both NOx and soot emissions are major concerns in compression ignition (CI) engine with diesel fuel and the enhancement of variety of fuel and air can increase the performance of combustion engine. There are several methods ...

Change of measure in fractional stochastic differential equation
(Semnan University, 20220101)Change of measure is a very well known common criterion in both the probability rules and applications. The change of measure is a transformation from actual measure to equivalent measure. We will employ the change of ...
