Jackknifed Liutype estimator in the ConwayMaxwell Poisson regression model
(Semnan University, 20220101)Modelling of count data has been of extreme interest to researchers. However, in practice, count data is often identified with overdispersion or underdispersion. The Conway Maxwell Poisson regression model (CMPRE) has been ...

Jackknifed Liutype estimator in the negative binomial regression model
(Semnan University, 20220101)The Liu estimator has been consistently demonstrated to be an attractive shrinkage method to reduce the effects of Intercorrelated (multicollinearity). The negative binomial regression model is a wellknown model in the ...

Julia sets are Cantor circles and Sierpinski carpets for rational maps
(Semnan University, 20220101)In this work, we study the family of complex rational maps which is given by$$Q_{\beta }\left(z\right)=2{\beta }^{1d}z^d\frac{z^d(z^{2d}{\beta }^{d+1})}{z^{2d}{\beta }^{3d1}},$$where $d$ greater than or equal to 2 ...

LaguerreChebyshev PetrovGalerkin method for solving integral equations
(Semnan University, 20220101)This project aims to solve the second kind of Volterra, Fredholm integrodifferential equations, and mixed integral equations (VIDE, FIDEs and MIEs respectively) will be solved using the LaguerreChebyshev PetrovGalerkin ...

A landscape view of deepfake techniques and detection methods
(Semnan University, 20220101)Deep fakes is the process of changing the information of the image or video with different techniquesand methods that start with humor and fun and sometimes reach economic, political and social goalssuch as counterfeiting, ...

The largest size of the arc of degree three in a projective plane of order sixteen
(Semnan University, 20220101)An $(n;3)$arc $ K $ in projective plane $ PG(2,q) $ of size n and degree three is a set of $ n $ points satisfies that every line meets it in less than or equal three points, also it is complete if it is not contained in ...

Legendre Kantorovich methods for Uryshon integral equations
(Semnan University, 20220101)In this paper, the Kantorovich method for the numerical solution of nonlinear emph{Uryshon} equations with a smooth kernel is considered. The approximating operator is chosen to be either the orthogonal projection or an ...

A lightweight intrusion detection system based on RSSI for sybil attack detection in wireless sensor networks
(Semnan University, 20220101)As the prevalence of Wireless Sensor Networks (WSNs) grows in the many missioncritical applications such as military and civil domains, the need for network security has become a critical concern. The inherently vulnerable ...

Linear operator of various types and its basic properties
(Semnan University, 20220101)We are starting to construct a new theory of linear operators of various types defined on fuzzy normed space inspired by the theory of linear operators of various types defined on ordinary normed space. The first goal in ...

LiuType estimator in gamma regression model based on (r(kd)) class estimator
(Semnan University, 20220101)It is known that when the multicollinearity exists in the gamma regression model, the variance of maximum likelihood estimator is unstable and high. In this article, a new Liutype estimator based on (r(kd)) class estimator ...

A local densitybased outlier detection method for high dimension data
(Semnan University, 20220101)The researchers faced challenges in the outlier detection process, mainly when deals with the high dimensional dataset; to handle this problem, we use The principal component analysis. Outlier detection or anomaly detection, ...

Mathematical analysis wavelets characteristics and their applications
(Semnan University, 20220101)Wavelets are now perceived as a groundbreaking new mathematical apparatus in signal and picture handling, time arrangement analysis, geophysics, guess hypothesis, and numerous various zones. Wavelet analysis has been an ...
