(Semnan University, 20220101)Due to the nature of activities and processes, the petrochemical industry causes the production of industrial effluents, emissions and wastes that have adverse effects on the environment. The purpose of this study is to ...

A hybrid ARFIMAfuzzy time series (FTS) model for forecasting daily cases of Covid19 in Iraq
(Semnan University, 20220101)Most time series are characterized in practice that they consist of two components, linear and nonlinear, and when making predictions, the single models are not sufficient to model these series. Recently several linear, ...

Solving multiobjectives function problem using branch and bound and local search methods
(Semnan University, 20220101)In this paper we consider $1//\sum^n_{j=1}{(E_j+T_j+C_j+U_j+V_j)}$ problem, the discussed problem is called a Multi objectives Function (MOF) problem, As objective is to find a sequence that minimizes the multiple objective ...

Dynamic modeling and microgrid frequency control connecting to the power grid in different modes
(Semnan University, 20220101)In this paper, using the potential of microgrid surface batteries, the frequency support of the power system in different operating modes was discussed. The study suggested that the process could be supported by a set of ...

Comparison between two new censored regression models extended from BurrXII system with application
(Semnan University, 20220101)This article presents a comparison between two new censored regression models which are extended from some continuous distribution with the BurrXII system. The two models are the LogBXII Weibull model(LBXIIW) and the ...

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 ...

Developing and explaining a comprehensive competency model of financial managers in a professional and forwardlooking manner with grounded theory method
(Semnan University, 20220101)Financial development in the country requires competent financial managers and optimal financial management. In this regard, developing a comprehensive perspective model to identify the competencies of financial managers ...

Finger vein recognition based on PCA and fusion convolutional neural network
(Semnan University, 20220101)Finger vein recognition and user identification is a relatively recent biometric recognition technology with a broad variety of applications, and biometric authentication is extensively employed in the information age. As ...

Improving completion time and execution time using FSMPIA: A case study
(Semnan University, 20220101)Cloud computing (CC) has facilitated the use, access, and storage of resources via sharing them with customers of different organizations. To shorten the completion time and execution time, we introduced the fuzzy kmeans ...

Boundedness of a new kind of Toeplitz operator on $2\pi$periodic holomorphic functions on the upper halfplane
