About solving stochastic It^{o}Volterra integral equations using the spectral collocation method
https://ijnaa.semnan.ac.ir/article_5007.html
10.22075/ijnaa.2019.13154.1680
1
The purpose of this paper is to propose the spectral collocation method to solve linear and nonlinear stochastic It^oVolterra integral equations (SVIEs). The proposed approach is different from other numerical techniques as we consider the Legendre Gauss type quadrature for estimating It^o integrals. The main characteristic of the presented method is that it reduces SVIEs into a system of algebraic equations. Thus, we can solve the problem by Newton's method. Furthermore, the convergence analysis of the approach is established. The method is computationally attractive, and to reveal the accuracy, validity, and efficiency of the proposed method, some numerical examples and convergence analysis are included.

Estimate survival function of the ToppLeone exponential distribution with application
https://ijnaa.semnan.ac.ir/article_5014.html
10.22075/ijnaa.2021.5014
1
This is a new lifetime Exponential "distribution using the ToppLeone generated family of distributions proposed by Rezaei et al. The new distribution is called the ToppLeone Exponential (TLE) distribution". What is done in this paper is an estimation of the "unlabeled two parameters for ToppLeone Exponential distribution model by using the maximum likelihood estimator method to get the derivation of the point estimators for all unlabeled parameters according to iterative techniques as Newton $$ Raphson method, then to derive Ordinary least squares estimator method". "Applying all two methods to estimate related probability functions; death density function, cumulative distribution function, survival function and hazard function (rate function)". When examining the numerical results for probability survival function by employing mean squares error measure and mean absolute percentage measure, this may lead to work on the best method in modeling a set of real data.

New subclasses of meromorphic biunivalent functions by associated with subordinate
https://ijnaa.semnan.ac.ir/article_5017.html
10.22075/ijnaa.2020.17405.1933

In the present paper, we define two subclasses $Sigma(lambda, alpha, beta)$, $Sigma_{mathcal C}(alpha, beta)$ of meromorphic univalent functions and subclass $Sigma_{{mathcal B},{mathcal C}}(alpha, beta, lambda)$ of meromorphic biunivalent functions. Furthermore, we obtain estimates on the general coefficients $b_n~(n ge1)$ for functions in the subclasses $Sigma(lambda, alpha, beta)$, $Sigma_{mathcal C}(alpha, beta)$ and estimates for the early coefficients of functions in subclass $Sigma_{{mathcal B},{mathcal C}}(alpha, beta, lambda)$ by associated subordination. The results obtained in this paper would generalize and improve those in related works of several earlier authors.

With the rapid development of technology, this development led to the emergence of microarray technology. It has the effect of studying the levels of gene expression in a way that makes it easier for researchers to observe the expression levels of millions of genes at the same time in a single experiment. Development also helped in the emergence of powerful tools to identify interactions between target genes and regulatory factors. The main aim of this study is to build models to predicate the relationship (Interaction) between Transcription Factors (TFs) proteins and target genes by selecting the subset of important genes (Relevant genes) from original dataset. The proposed methodology comprises into three major stages: the genes selection, merge datasets and the prediction stage. The process of reducing the computational space of gene data has been accomplished by using proposed mutual information method for genes selection based on the data of gene expression. In the prediction, the proposed prediction regression techniques are utilized to predict with binding rate between single TFtarget gene. It has been compared the efficiency of two different proposed regression techniques including: Linear Regression and Random Forest Regression. Two available data sets have been utilized to achieve the objectives of this study: Gene’s expression data of Yeast Cell Cycle dataset and Transcription Factors dataset. The evaluation of predictions performance has been performed depending on two performance prediction measures (Root Mean Square Error (RMSE) and Mean Absolute Error (MAE) with (10) FoldsCross Validation.

Dhage iteration principle for IVPs of nonlinear first order impulsive differential equations
https://ijnaa.semnan.ac.ir/article_5031.html
10.22075/ijnaa.2019.17188.1913

In this paper we prove the existence and approximation theorems for the initial value problems of first order nonlinear impulsive differential equations under certain mixed partial Lipschitz and partial compactness type conditions. Our results are based on the Dhage monotone iteration principle embodied in a hybrid fixed point theorem of Dhage involving the sum of two monotone order preserving operators in a partially ordered Banach space. The novelty of the present approach lies the fact that we obtain an algorithm for the solution. Our abstract main result is also illustrated by indicating a numerical example.

Sufficient conditions for convergence of the numerical method are given and their applicability is illustrated with some examples.In numerical examples we give two benchmark sample problems and compare the proposed method by the famous RungeKutta fourthorder method. These sample problems practically show some advantages of the NewtonTaylor polynomial solutions method.

Optimal pricing policy for stock dependent demand with effective investment in preservation technology
https://ijnaa.semnan.ac.ir/article_5033.html
10.22075/ijnaa.2020.17515.1943
1
In this paper, we suggested an optimal pricing policy for deteriorating items. To reduce the rate of deterioration, we apply a preservation technology and calculate the optimal preservation technology investment. The demand function is dependent on time, stock and selling price. Shortages are allowed in our consideration, and two cases are studied, first complete backordering and the second one is partially backordering. Our main objective is to find the optimal cycle length, ordering frequency the optimal preservation technology investment and the optimal selling price that maximizes the total profit. This model proves that the total profit is a concave function of the selling price, ordering frequency, preservation technology investment and time cycle. Numerical examples are provided to illustrate the features and advances of the model. A sensitivity analysis is performed in order to assess the stability of the proposed model.

Stability of (1,2)total pitchfork domination
https://ijnaa.semnan.ac.ir/article_5035.html
10.22075/ijnaa.2021.5035
1
Let $G=(V, E)$ be a finite, simple, and undirected graph without isolated vertex. We define a dominating $D$ of $V(G)$ as a total pitchfork dominating set, if $1leqN(t)cap VDleq2$ for every $t in D$ such that $G[D]$ has no isolated vertex. In this paper, the effects of adding or removing an edge and removing a vertex from a graph are studied on the order of minimum total pitchfork dominating set $gamma_{pf}^{t} (G)$ and the order of minimum inverse total pitchfork dominating set $gamma_{pf}^{t} (G)$. Where $gamma_{pf}^{t} (G)$ is proved here to be increasing by adding an edge and decreasing by removing an edge, which are impossible cases in the ordinary total domination number.

In this article, we discuss the piecewise polynomial based Galerkin method to approximate the solutions of second kind VolterraHammerstein integral equations. We discuss the convergence of the approximate solutions to the exact solutions and obtain the orders of convergence $mathcal O(h^{r})$ and $mathcal O(h^{2r}),$ respectively, for Galerkin and its iterated Galerkin methods in uniform norm, where $h, ~r$ denotes the norm of the partition and smoothness of the kernel, respectively. We also obtain the superconvergence results for multiGalerkin and iterated multiGalerkin methods. We show that iterated multiGalerkin method has the order of convergence $mathcal O(h^{3r})$ in the uniform norm. Numerical results are provided to demonstrate the theoretical results.

In this article, we are going to study the stability and bifurcation of a twodimensional discrete time vocal fold model. The existence and local stability of the unique fixed point of the model is investigated. It is shown that a NeimarkSacker bifurcation occurs and an invariant circle will appear. We give sufficient conditions for this system to be chaotic in the sense of Marotto. Numerically it is shown that our model has positive Lyapunov exponent and is sensitive dependence on initial conditions. Some numerical simulations are presented to illustrate our theoretical results.

Convergence theorems of a new multiparametric family of Newtonlike method in Banach space
https://ijnaa.semnan.ac.ir/article_5046.html
10.22075/ijnaa.2020.17555.1948
1
In this work, we have considered a new multiparametric family of modified Newtonlike methods(MNL) of order three to approximate a zero of a nonlinear operator in $mathbb{B}$space (Banach space). Here, we studied the semilocal convergence analysis of this family of methods by using a new type of majorant condition. Note that this majorant condition generalizes the earlier majorant conditions used for studying convergence analysis of third order methods. Moreover, by using secondorder directional derivative of the majorizing function we obtained an error estimate. We also established relations between our majorant condition and assumption based on Kantorovich, Smaletype and NesterovNemirovskiitype, that will show our result generalize these earlier convergence results.

In this manuscript, we initiate an almost $alpha$$F$contraction and an almost $alpha$$F$ weak contraction in the setting of partial metric spaces and establish adequate conditions for the presence of fixed points. The obtained results generalize the classical and recent results of the literature, which are validated by suitable examples. As applications of these established results, we solve a nonlinear fractional differential equation and a boundary value problem.

A Robust Encryption Technique Using Enhanced Vigenre Cipher
https://ijnaa.semnan.ac.ir/article_5071.html
10.22075/ijnaa.2021.5071
1
A lot of data in this world are very important and no matter how simple it can be. Hence the number of data conveyed through the internet still increasing due to the rapid development of computer technology. In order to save the data over the internet, cryptography is a technique for conveying information securely between two parties without interference from outside elements. The Vigenre cipher is a technique of encrypting alphabetic text via using a sequence of different Caesar ciphers depend on the letters of a keyword. It is a simple form of polyalphabetic replacement. In this paper, the traditional way for the Vigenre method is enhanced by using two keys for text encryption. The first key is used to format the table of the alphabet (26 characters) and second keys are used to encrypt the plain text like the original Vigenre cipher. The result shows the proposed method is efficient and stronger against the kasiski and Friedman attack to find the length of the key.

Kalman filter and ridge regression backpropagation algorithms

The Kalman filter (KF) compare with the ridge regression backpropagation algorithm (RRBp) by conducting a numerical simulation study that relied on generating random data applicable to the KF and the RRBp in different sample sizes to determine the performance and behavior of the two methods. After implementing the simulation, the mean square error (MSE) value was calculated, which is considered a performance measure, to find out which two methods are better in making an estimation for random data. After obtaining the results, we find that the Kalman filter has better performance, the higher the randomness and noise in generating the data, while the other algorithm is suitable for small sample sizes and where the noise ratios are lower.

Let M be a unitary left Rsemimodule where R is a commutative semiring with identity. The small intersection graph G(M) of a semimodule M is an undirected simple graph with all non small proper subsemimodules of M as vertices and two distinct vertices N and L are adjacent if and only if N ∩ L is not small in M. In this paper, we investigate the fundamental properties of these graphs to relate the combinatorial properties of G(M) to the algebraic properties of the Rsemimodule M. Determine the diameter and the girth of G(M). Moreover, we study cut vertex, clique number, domination number and independence number of the graph G(M). It is shown that the independence number of small graph is equal to the number of its maximal subsemimodules.

Strong convergence theorems for minimization, variational inequality and fixed point problems for quasinonexpansive mappings using modified proximal point algorithms in real Hilbert spaces

In this paper, we investigate the problem of finding a common element of the solution set of convex minimization problem, the solution set of variational inequality problem and the solution set of fixed point problem with an infinite family of quasinonexpansive mappings in real Hilbert spaces. Based on the wellknown proximal point algorithm and viscosity approximation method, we propose and analyze a new iterative algorithm for computing a common element. Under very mild assumptions, we obtain a strong convergence theorem for the sequence generated by the proposed method. Application to convex minimization and variational inequality problems coupled with inclusion problem is provided to support our main results.,Our proposed method is quite general and includes the iterative methods considered in the earlier and recent literature as special cases.

The Sumudu homotopy perturbation method (SHPM) is applied to solve fractional order nonlinear differential equations in this paper.The current technique incorporates two notable strategies in particular Sumudu transform (ST) and homotopy perturbation method (HPM). The proposed method’s hybrid property decreases the number of the quantity of computations and materials needed. In this method, illustration examples evaluate the accuracy and applicability of the mentioned procedure. The outcomes got by FSHPM are in acceptable concurrence with the specific arrangement of the problem.

In this article a mathematical model with twin objectives is presented. The objectives are considered as:Minimization of the maximum tardiness of tasks completion time and the total early tasks penalties. Since tasks timing is a tardy and indefinite factor in cloud computing; therefore problem solving model is used as the combined Metaheuristic innovative algorithm of multi objective swarm of particles based Parto archive has been used. The suggested algorithm with genetic operators as well as the directed and repeated counterpart structures in the format of multi operators are taken to assess the algorithm application. The results will be sorted based on quality, distraction, integrated, the number of nondefeated solutions and the gap from the ideal one is compared with the evolutionary algorithm results titled genetic algorithm. The final results of solved model indicate that firstly, this algorithm is stronger than NSGAII algorithm but is weaker in timing, norms and scales. In other words, the suggested algorithm, is more capable to discover solutions, accordingly.

Nonlinear instability analysis of a vertical cylindrical magnetic sheet
https://ijnaa.semnan.ac.ir/article_5111.html
10.22075/ijnaa.2020.19429.2078
1
This paper concerns with the nonlinear instability analysis of double interfaces separated three perfect, incompressible cylindrical magnetic fluids. The cylindrical sheet is acted upon by an axial uniform magnetic field. The current nonlinear approach depends mainly on solving the linear governing equations of motion and subjected to the appropriate nonlinear boundary conditions. This procedure resulted in two nonlinear characteristic equations governed the behavior of the interfaces deflection. By means of the Taylor expansion, together with the multiple time scales, technique, the stability analysis of linear as well as the nonlinear is achieved. The linear stability analysis reveals a quadratic dispersion equation in the square of growth rate frequency of the surface wave. On the other hand, the nonlinear analysis is accomplished by a coupled nonlinear Schrödinger equation of the evolution amplitudes of the surface waves. The stability criteria resulted in a polynomial of the eleventh degree in the square of the magnetic field strength, together with resonance transition curves. Several special cases are reported upon appropriate data choices. The stability criteria are numerically discussed, at which regions of stability and instability are identified. In the stability profile, the magnetic field intensity is plotted versus the wave number. The influences of the parameters on the stability are addressed. The nonlinear stability approach divides the phase plane into several parts of stability/instability. The nonlinear stability shows an in contrast mechanism of the role of the sheet thickness.

In this paper, we have studied the degree of approximation of certain bivariate functions by double factorable matrix means of a double Fourier series. Four theorems are proved using single rest bounded variation sequences, single head bounded variation sequences, double rest bounded variation sequences, and two nonnegative mediate functions. These results expressed in terms of two functions of modulus type and two nonnegative mediate functions, imply many particular results as shown at last section of this paper.

Using the infimum form of auxiliary functions to study the common coupled coincidence points in fuzzy semimetric spaces
https://ijnaa.semnan.ac.ir/article_5118.html
10.22075/ijnaa.2020.13960.1728

The common coupled coincidence points and common coupled fixed points in fuzzy semimetric spaces are investigated in this paper. In fuzzy semimetric space, the symmetric condition is not necessarily assumed to be satisfied. In this case, regarding the nonsymmetry of metric, there are four kinds of triangle inequalities that can be considered. In order to investigate the common coupled coincidence points and common coupled fixed points, the fuzzy semimetric space is further assumed to satisfy the socalled canonical condition that is inspired from the intuitive observations. The sufficient conditions for guaranteeing the common coupled coincidence points and common coupled fixed points will be different for the four different kinds of triangle inequalities.

Dynamical analysis, stability and discretization of fractionalorder predatorprey model with negative feedback on two species
https://ijnaa.semnan.ac.ir/article_5124.html
10.22075/ijnaa.2020.19764.2099

The LotkaVolterra model is an important model being employed in biological phenomena to investigate the nonlinear interaction among existing species. In this work, we first consider an integer order predatorprey model with negative feedback on both prey and predator. Then by introducing a fractional model into the existing one, we give them a specified memory. We also obtain its discretized counterpart. Finally, along with giving the biological interpretation of the system, the stability and dynamical analysis of the proposed model are investigated and the results are illustrated as well.

Hybrid medical image compression using the IKL transform with an efficient encoder
https://ijnaa.semnan.ac.ir/article_5126.html
10.22075/ijnaa.2021.5126
1
Medical images are generated in a huge number in the research centers and hospitals every day. Working with the medical images and maintain the storage needs an efficient fund and huge storage space. Retaining the quality of the medical image is also very essential. Image compression without losing its quality is the only term to achieve the desired task. Achieving the desired task using the integer Karhunen Loeve transform attains a quality output and also with less storage space. JPEG and JPEG 2000 are also challenging to the integer transform based compression. Resulting the compression quality in terms of peak signal noise ratio, compression ratio is attained. Proposed method of compression is compared with the other efficient algorithms. Thus this proposed method can be used efficiently for the medical image in order to store and retrieve in healthcare industry.

In this paper, we investigate a shrinking algorithm for finding a solution of split monotone variational inclusion problem which is also a common fixed point problem of relatively nonexpansive mapping in uniformly convex real Banach spaces which are also uniformly smooth. The iterative algorithm employed in this paper is design in such a way that it does not require prior knowledge of operator norm. We prove a strong convergence result for approximating the solutions of the aforementioned problems and give applications of our main result to split convex minimization problem. The result present in this paper extends and complements many related results in literature.

A new method of linear support vector regression with interval data
https://ijnaa.semnan.ac.ir/article_5144.html
10.22075/ijnaa.2020.19163.2067
1
In this paper, the linear support vector regression approach is proposed for solving the regression problem with interval data, which is called interval support vector regression(ISVR). The ISVR approach is equivalent to solving a linear constrained quadratic programming problem (QPP) with an interval cost coefficient in which the value of the objective function is in an interval. Instead of solving an interval QPP, we solve two QPPs and prove that the cost values of these two problems are the lower bound and the upper bound of the target value of the interval QPP. We show these two mentioned QPPs are equivalent to two support vector regression problems which the first problem applies the lower bound of data and the second problem considers the upper bound of the data. to obtain the regression function. Some experiments are made to demonstrate the performance of our method compared with the known algorithms on several artificial, benchmark and real practical datasets.

With the growing number of cyber security threats affecting the business environment of many organizations, especially the IT environment. With the growing number of cyber security threats affecting the business environment of many organizations, especially the IT environment. Managed protection systems, including SOC, are highly sought after. Managed protection systems, including SOC, are highly sought after. The problem with SOC is that when building up their own SOC or hiring a thirdparty to provide SOC, organizations are not able to apply adequate criteria or standard frameworks. The aim of the study is to lay the foundations for developing a modern system of systematic operation centers for the next generation (NGSOC) for IIoT climate. This paper contains thorough, qualitative literature survey on the implementation of a Security Operation Centre (SOC). A comparative study is carried out using a variety of previous research sources and a literature review. The findings from the report show that previous research is not adequately guided, especially in the safety and technical aspects of the building block of the SOC. It is hoped that by proposing the framework, cybersecurity threat prevention and identification would be strengthened even further. The success of the NGSOC will ultimately be determined by the integration of individuals, procedure, and technology.

An inverse triple effect domination in graphs
https://ijnaa.semnan.ac.ir/article_5147.html
10.22075/ijnaa.2021.5147
1
In this paper, an inverse triple effect domination is introduced for any finite graph $G=(V, E)$ simple and undirected without isolated vertices. A subset $D^{1}$ of $VD$ is an inverse triple effect dominating set if every $v in D^{1}$ dominates exactly three vertices of $VD^{1}$. The inverse triple effect domination number $gamma_{t e}^{1}(G)$ is the minimum cardinality over all inverse triple effect dominating sets in $G$. Some results and properties on $gamma_{t e}^{1}(G)$ are given and proved. Under any conditions the graph satisfies $gamma_{t e}(G)+gamma_{t e}^{1}(G)=n$ is studied. Lower and upper bounds for the size of a graph that has $gamma_{t e}^{1}(G)$ are putted in two cases when $D^{1}=VD$ and when $D^{1} neq VD .$ Which properties of a vertex to be belongs to $D^{1}$ or out of it are discussed. Then, $gamma_{t e}^{1}(G)$ is evaluated and proved for several graphs.

In late 2019, a virus appeared suddenly he claims Covid19, which started in China and began to spread very widely around the world. And because of its effects, which are not limited to human life only, but rather in economic and social aspects, and because of the increase in daily injuries and significantly with the limited hospitals that cannot accommodate these large numbers, it is necessary to find an automatic and rapid detection method that limits the spread of the disease and its detection at an early stage in order to be treated more quickly. In this paper, deep learning was relied upon to create a CNN model to detect COVID19 infected lungs using chest Xray images. The base consists of a set of images taken of lungs infected with Covid19 disease and normal lungs, as the CNN structure gave accuracy, Precision, Recall and FMeasure 100%

The early school dropout is very significant portents that controls the future of societies and determine the nature of its elements. Therefore, studying this phenomenon and find explanations of it is a necessary matter, by finding or developing appropriate models to predict it in the future. The variables that affect the early school dropout Iraq takes a large size and multiple sources and types due the political and economic situation , which attributes it as a sort of Big Data that must be explored by using new statistical approaches. The research aims at using one Covariate at a Time Multiple Testing OCMT Method to analyze the data from surveys collected by the Central Statistical Organization IRAQ, which contains many indicators related to school dropout and meaningfully affect the life of the Iraqi persons. The Ridge Regression Method as well as the OCMT method were chosen to analyze data and the Mean Square Errors MSE was used to compare the two methods and From the results we find that OCMT estimator is better than Ridge estimator with Big Data conditions.

Effects of static magnetic field on dye extracted from AnchusaItalica through optimization the optoelectronic properties
https://ijnaa.semnan.ac.ir/article_5158.html
10.22075/ijnaa.2021.5158
1
The dye extracted from the plant is already well used in optoelectronic applications for its easy and safe handling. This study is to demonstrate the effect of magnetized distilled water on dye extracted from AnchusaItalica flowers. The results of its optoelectronic behavior reveal that the use of magnetized water in the extraction process results in different and better properties than processes in which ordinary water was used. The structural analysis of AnchusaItalica dye thinfilm was performed using the Fouriertransform infrared technique (FTIR). The optical responses, such as the absorption coefficient, absorption spectra, both standard and refractive indices, and electronic properties (optical energy gap) were studied using UltravioletVisible transmittance spectra range 300–900 nm. The calculated energy band gap of the dye extracted using magnetized water was decreased from 3.23 to 2.35 eV and turned into the preferred direct band gap to make a useful contribution to optical sources. The optical absorption spectra of the dye extracted using magnetized water appear to have a better efficiency compared to that extracted with ordinary water. A significant evolution in the absorption coefficient was obtained by employing magnetized water to extract the dye. The magnetized extraction process also modified the electronic transmission values (indirect to direct). The effect of magnetized water on the resonance mode and transparent indication was deduced by studying the complex refractive index. An increase appeared in the spectrum of the absorption index at a wavelength of 570 nm, whereas a small attenuation coefficient was observed as well. The important effects of magnetized dye extraction will highly benefit the field of optoelectronic applications.

Bayes estimators of a multivariate generalized hyperbolic partial regression model
https://ijnaa.semnan.ac.ir/article_5166.html
10.22075/ijnaa.2021.5166

The matrixvariate generalized hyperbolic distribution belongs to the family of heavytailed mixed
probability distributions and is considered to be one of the continuous skewed probability distributions. This distribution has wide applications in the field of economics, especially in stock modeling.
This paper includes estimation the parameters of the multivariate semiparametric regression
model represented by the multivariate partial linear regression model when the random error follows the matrixvariate generalized hyperbolic distribution, using the Bayesian method when noninformative prior information is available and under the assumption that the shape parameters and
the skewness matrix are known. In addition, the bandwidth parameter is estimated by a suggested
way based on the normal distribution rule and the proposed kernel function based on the mixed
Gaussian kernel function and studying the findings on the generated data in a way suggested for
the model, comparing the estimators depending on the criterion of the mean sum of squares error.
The two researchers concluded that the proposed kernel function is better than the Gaussian kernel
function in estimate the parameters.

A new approach of classical Hill Cipher in public key cryptography
https://ijnaa.semnan.ac.ir/article_5176.html
10.22075/ijnaa.2021.5176
1
Secure message transformation promote the creation of various cryptography systems to enable receivers to interpret the transformed information. In the present age of information technology, the secure transfer of information is the main study of most agencies. In this study, a particular symmetric cryptography system, Hill Cipher method, is enhanced with the help of encryption and decryption algorithms of the asymmetric RSA cryptography system to avoid certain problems. Previous results show that the original Hill algorithms are still insufficient because of their weakness to known plaintext attack, and a modification of the Hill Cipher cryptography system is therefore presented to increase its invulnerability. The enhancement focuses on implementing the RSA algorithms over the Hill Cipher to increase its security efficiency. The suggested method relies on the security of the RSA and Hill Cipher cryptosystems to find the private decryption keys, and thus is much more secure and powerful than both methods applied separately. Also secure and dynamic generation of the Hill Cipher matrix instead of using static matrix are proposed. This new approach is composed of a public key cryptosystem that has a shared secret key (between participants only), public key (announced to all), and two private keys (for each person). Therefore, this new modification can increase the invulnerability of the Hill Cipher against future attacks during transmission of information between agencies in this age of information technology

Face recognition via weighted nonnegative sparse representation
https://ijnaa.semnan.ac.ir/article_5187.html
10.22075/ijnaa.2021.5187
1
Face recognition is one of the most important tools of identification in biometrics. Face recognition has attracted great attention in the last decades and numerous algorithms have been proposed. Different researches have shown that face recognition with Sparse Representation based Classification (SRC) has great classification performance. In some applications such as face recognition, it is appropriate to limit the search space of sparse solver because of local minima problem. In this paper, we apply this limitation via two methods. In the first, we apply the nonnegative constraint of sparse coefficients. As finding the sparse representation is a problem with very local minima, at first we use a simple classifier such as nearest subspace and then add the obtained information of this classifier to the sparse representation problem with some weights. Based on this view, we propose Weighted Nonnegative Sparse Representation WNNSR for the face recognition problem. A quick and effective way to identify faces based on the sparse representation (SR) is smoothed $L_0$norm $(SL_0)$ approach. In this paper, we solve the WNNSR problem based on the $SL_0$ idea. This approach is called Weighted NonNegative Smoothed $L_0$ norm $(WNNSL_0)$. The simulation results on the Extended Yale B database demonstrate that the proposed method has high accuracy in face recognition better than the ultramodern sparse solvers approach.

Multiobjective optimization with modified Taguchi approach to specify optimal robot spray painting process parameters
https://ijnaa.semnan.ac.ir/article_5193.html
10.22075/ijnaa.2021.5193
1
Robot spray painting process can improve the quality, productivity and provide clean environment in addition to minimize the labour and cost. This process is being used in automobiles, home appliances, etc. There is a need to specify optimal spray painting process parameters to improve the quality of paint coating considering the performance indicators as thickness variation, surface roughness and film adhesion. Compared to the Taguchi orthogonal array and gray rational analysis, a simple modified Taguchi approach is adopted here to identify optimal spray painting process parameters (such as distance, pressure and speed) and obtain minimum thickness variation, minimum surface roughness and maximum film adhesion. Empirical relation for thickness variation, surface roughness and film adhesion are presented. Test data are closeto/within the estimated range.

In this paper, the study detects the nutritional deficiencies from these leaves using Internet of Thing (IoT) based image acquisition and nutrition analyser devices. The former captures the color of the leaf and the latter helps in finding the nutrients in each zone based on the image captured by the device. The study uses an improved convolutional neural network to detect automatically the nutrients present in a leaf. The type of leaf is considered from the plants including coriander, tomato, pepper, chili, etc. The Convolutional Neural Network (CNN) is used to extract the patterns of leaf images from the data capturing IoT devices and nutrition analyser device. The system stores and process the data in cloud, where the CNN integrated in Virtual Machines enables the process of input data and process it and sends the report to the authority. A total of 3000 images are collected out of various disorders in five different plants. A 5 fold crossvalidation is conducted on training and testing dataset. The system is tested in terms of accuracy, sensitivity, specificity, fmeasure, geometric mean and percentage error. The comparison made with existing models shows an improved detection accuracy by CNN than other deep learning models.

The community's rise, public opinion network's popularity, and emergency personnel's advancement have changed drastically. Individuals can now go online from any place and through communications systems to share their opinions and attitudes more efficiently and more often. As illustrated by the preceeding network approach, public sentiment on neural networks and IoT is critical for the public sector, the public interest, and a special event in an emergency (IoT). In terms of data security and anonymity, the proposed program is not safe and has environmental problems. Network public opinion's approach is based on FPGAs and machine education. FPGAs (Field Programmable Gate Array) Instant perspectives, possible future themes, knowledge exchange, excellent content and Team variance are used to build machine learning. In this popular sentiment network, several disasters have seriously threatened the security of our community. Public views on disaster networks in all type of internet media, such as internet news, blogs and webpages, are inextricably connected with society. This plays into unprecedented stress the ability of the government to deal with crises and their consequences.

A new modification of Kalman filter algorithm
https://ijnaa.semnan.ac.ir/article_5221.html
10.22075/ijnaa.2021.5221
1
This study is concerned with estimating random data and in the presence of noise, as we used the Kalman filter estimation method through the backpropagation algorithm to estimate these data. This is because modern estimation methods have become more important as they were in the past years due to the expansion of the field of science and technology and the increasing data Therefore, the interest became in estimation methods that solve the noise problems that occur in the data. The Kalman filter has become one of the most popular and most reliable estimators in case of data noise. This study tests the use of the Kalman filter and Back Propagation algorithm to estimate the data containing noise and compare the results with the proposed method on the same data. The data is generated randomly in the simulation study. The results showed that Kalman is more efficient in filtering noise from the data and giving a lower mean square error compared to the backpropagation algorithm, but the results of the proposed method outperformed the results of the Kalman filter and the backpropagation with the least possible error.

Modelling covid19 data using double geometric stochastic process
https://ijnaa.semnan.ac.ir/article_5224.html
10.22075/ijnaa.2021.5224
1
Some properties of the geometric stochastic process (GSP) are studied along with those of a related process which we propose to call the Double geometric stochastic process (DGSP), under certain conditions. This process also has the same advantages of tractability as the geometric stochastic process; it exhibits some properties which may make it a useful complement to the multiple Trends geometric stochastic process. Also, it may be fit to observed data as easily as the geometric stochastic process. As a first attempt, the proposed model was applied to model the data and the Coronavirus epidemic in Iraq to reach the best model that represents the data under study. A chicken swarm optimization algorithm is proposed to choose the best model representing the data, in addition to estimating the parameters a, b, (mu), and (sigma^{2}) of the double geometric stochastic process, where (mu) and (sigma^{2}) are the mean and variance of (X_{1}), respectively.

Financial fraud is a serious problem in banking system. Credit card fraud is growing with increasing Internet usage, as it becomes very simple to collect user data and do fraud transaction. Fortunately, all records including fraud and legit transactions are present in the financial record. Improved data mining techniques are now capable to find solutions for such outlier detections. Financial data is freely available in many sources, but this data has some challenges like,1) the profile of legit and fraudulent behavior changes constantly, 2) there is a class imbalance problem in dataset, because less than 3% transaction are fraud, 3) transaction verification latency is also one more problem. All this data issues are handled using preprocessing techniques like cleaning and reduction. Main aim of this research is to find out, output attribute "is Fraud", with better time complexity. To this end, Kmeans, Random Forest and J48 algorithm is used, and its accuracy rates are compared to find best fit preprocessing and machine learning algorithm. It is observed that accuracy rate of Random Forest is 93.8% when both global and local dataset is used.

In this paper, we introduce a condition on mappings and show that the class of these mappings is broader than both the class of mappings satisfying condition (C) and the class of fundamentally nonexpansive mappings, and it is incomparable with the class of quasinonexpansive mappings and the class of mappings satisfying condition (L). Furthermore, we present some convergence theorems and fixed point theorems for mappings satisfying the condition in the setting of Banach spaces. Finally, an example is given to support the usefulness of our results.

A secure ECG signal transmission for heart disease diagnosis
https://ijnaa.semnan.ac.ir/article_5235.html
10.22075/ijnaa.2021.5235
1
Due to the high sampling rate, the recorded Electrocardiograms (ECG) data are huge. For storing and transmitting ECG data, wide spaces and more bandwidth are therefore needed. The ECG data are also very important to preprocessing and compress so that it is distributed and processed with less bandwidth and less space effectively. This manuscript is aimed at creating an effective ECG compression method. The reported ECG data are processed first in the preprocessing unit (ProUnit) in this method. In this unit, ECG data have been standardized and segmented. The resulting ECG data would then be sent to the Compression Unit (CompUnit). The unit consists of an algorithm for lossy compression (LosyComp), with a lossless algorithm for compression (LossComp). The randomness ECG data is transformed into high randomness data by the failure compression algorithm. The data's high redundancy is then used with the LosyComp algorithm to reach a high compression ratio (CR) with no degradation. The LossComp algorithms recommended in this manuscript are the Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT). LossComp algorithms such as Arithmetic Encoding (Arithm) and Run Length Encoding (RLE) are also suggested. To evaluate the proposed method, we measure the Compression Time (CompTime), and Reconstruction Time (RecTime) (T), RMSE and CR. Simulation results suggest the highest output in compression ratio and in complexity by adding RLE after the DCT algorithm. The simulation findings indicate that the inclusion of RLE following the DCT algorithm increases performance in terms of CR and complexity. With CR = 55% with RMSE = 0:14 and above 94% with RMSE = 0:2, DCT as a LossComp algorithm was utilized initially, followed by RLE as a LossComp algorithm.

Explaining the role of financial leverage speed of adjustment (SOA) during the firm life cycle
https://ijnaa.semnan.ac.ir/article_5266.html
10.22075/ijnaa.2021.23393.2528

This paper analyzes differences in speed of adjustment (SOA) across three life cycle stages of European listed firms: introduction, growth, maturity, decline, and fall. Dickenson's model based on cash flow has been used to divide different periods. For this purpose, the role of four determinants of profitability and intangible assets, growth opportunities, and size on SOA was investigated using the GMM (generalized torque) method. For this purpose, 153 firms listed firms on the Tehran Stock Exchange in the ten years 20092019 were selected, and data were analyzed by Stata and Eviews software. The results do not support by tradeoff theory (TOT) and pecking order theory (POT) because according to these theories, the SOA of financial leverage is not completed during different stages of the life cycle. Higher speed in the introduction stage provides a different analysis than the growth stage. In addition, results show a lower increase in costs for firms that change from growth to maturity than for firms that change from introduction to growth.

Improving air pollution detection accuracy and status monitoring based on supervised learning systems and Internet of Things
https://ijnaa.semnan.ac.ir/article_5278.html
10.22075/ijnaa.2021.5278
1
In recent decades air pollution and its associated health risks are in growing numbers. Detecting air pollution in the environment and alarming the people may accomplish various advantages among health monitoring, telemedicine, and industrial sectors. A novel method of detecting air pollution using supervised learning models and an alert system using IoT is proposed. The main aim of the research is manifold: a) Air pollution data is preprocessed using the feature scaling method, b) The feature selection and feature extraction process done followed by performing a Recurrent Neural Network and c) The predicted data is stored in the cloud server, and it provides the endusers with an alert when the threshold pollution index exceeds. The proposed RNN reports enhanced performance when tested against traditional machine learning models such as Convolutional Neural Networks (CNN), Deep Neural Networks(DNN), and Artificial Neural Networks(ANN) for parameters such as accuracy, specificity, and sensitivity.

Electronic Health Record (EHR) holds immensely sensitive information and consisting of crucial data related to the patients. Storing and organizing such data is highly arduous task. Researches still going on to improve the Quality of Service (QOS) of such data. Existing study focused only on improving the system throughput, privacy and latency issues. But they did not tend to scrutinize the scalability and privacy of such data records. In this paper, we propose a novel deep learning framework to improve the Quality of Service using block chain technology. Initially the data is classified into high priority and low priority based on its nature by using Recurrent Neural Network (RNN). Then, the classified high priority data is further allowed to each block of a block chain and the low priority data is stored and maintained as log file. Finally, the results are compared based on the evaluation metrics which demonstrates our proposed novel deep learning framework achieves better accuracy.

Using alignmentfree methods as preprocessing stage to classification whole genomes

In bioinformatics systems, the study of genetics is a popular research discipline. These systems depend on the amount of similarity between the biological data. These data are based on DNA sequences or raw sequencing reads. In the preprocessing stage, there are several methods for measuring similarity between sequences. The most popular of these methods is the alignment method and alignmentfree method, which are applied to determine the amount of functional matching between sequences of nucleotides DNA, ribosome RNA, or proteins. Alignmentbased methods pose a great challenge in terms of computational complexity, In addition to delaying the time to search for a match, especially if the data is heterogeneous and its size is huge, and thus the classification accuracy decreases in the postprocessing stage. Alignmentfree methods have overcome the challenges of alignmentbased methods for measuring the distance between sequences, The size of the data used is 1000 genomes uploaded from National Center for Biotechnology Information (NCBI), after eliminating the missing and irrelevant values, it becomes 860 genomes, ready to be segmented into words by the kmer analysis, after which the frequency of each word is counted for each query. The size of a word depends on a value of k. In this paper we used a value of k =3 ….8, for each iteration will count times of frequencies words.

In this paper, an efficient GV1CG is developed to optimizing the modified conjugate gradient algorithm by using a new conjugate property. This is to increase the speed of the convergence and retain the characteristic mass convergence using the conjugate property. This used property is proposed to public functions as it is not necessary to be a quadratic and convex function. The descent sharp property and comprehensive convergence for the proposed improved algorithm have been proved. Numerical results on some test function indicate that the new CGmethod outperforms many of the similar methods in this field.

Resilience in semantic networks: A new approach for studying language impairment in Alzheimer's disease
https://ijnaa.semnan.ac.ir/article_5284.html
10.22075/ijnaa.2021.22221.2339

Language Impairment in Alzheimer's disease can occur because of deficits in semantic levels of language processing. It can be studied using computational models of language such as complex semantic networks which are strongly related to semantic memory. We hypothesize that the concept of resilience in scalefree semantic networks can truly model and predict semantic language deficit in Alzheimer's disease. We suggest that increasing the variety of words in the lexicon of patients with Alzheimer's disease, improves the resilience of their semantic networks through breakdowns. Moreover, enlarging the size of the semantic networks of patients with Alzheimer's disease can make these networks more resilient.

The phased array antenna is one of the most significant applications in fifthgeneration mobile networks. It is one of the most important applications in fifthgeneration networks. An electric power source that powers the whole application, including the antenna's root, is required. Even with the most outstanding design, if the programme does not have a sound power supply system with minimal packet loss and can't Path find performance, it will be rendered ineffective. When seen from the perspective of the multiplex information, Machine Learning comprises a communication network based on the Internet that transmits information to the control centre via the objects (IOT). To put it another way, the proposed communication infrastructure, via the provision of, and the chance microgrid state to collect, analyze, and twoway communication link control information, offers the chance to resolve the voltage regulation issues. This cuttingedge communication infrastructure, as well as a suggested state estimation filter focused on improving speed and performance in renewable energy production, are both examples of creative communication infrastructure. Current research is focused on analyzing and enumerating a range of energy abundances in the context of smart grids, which are now in their fifth generation. Rather than concentrating on the future development plan, which should be a problem of illusion, it should concentrate on the composition of the future potential of smart grid communications framework. An indepth investigation to give evidence to the Machine learning will help intelligent networks in the future conduct a thorough evaluation.

In this article, we extended an efficient computational method based on Walsh operational matrix to find an approximate solution of nonlinear fractional order Volterra integrodifferential equation, First, we present the fractional Walsh operational matrix of integration and differentiation. Then by applying this method, the nonlinear fractional Volterra integrodifferential equation is reduced into a system of algebraic equation. The benefits of this method are the lowcost of setting up the equations without applying any projection method such as collocation, Galerkin, etc. The results show that the method is very accuracy and efficiency.

A secure biomedical data sharing framework based on mCloud
https://ijnaa.semnan.ac.ir/article_5295.html
10.22075/ijnaa.2021.5295

Medical Clouds (mCloud) utilized various wearable devices and sensors for better care for patients by encouraging the perspective of the clouds. It gives a more versatile way to centrally and in realtime compare the patients’ profiles in the conventional healthoffline system. However, due to the lack of appropriate security measures in lowpower computers, there are obstacles to data protection. The limitation made the data vulnerable to hacking and tamper when it transfers from one device to another. In available solutions, the devices send unencrypted data to a central server where it encrypts and forwards, ondemand, to requesting devices. There are two primary challenges in the approach: first, the data link is still vulnerable between the source device and central server; second, the response time of the server gets slower with an increasing number of devices. This manuscript proposes a secure and fasterdistributed method, which shares a patient’s data by various devices connected to the mCloud with health caregivers without the need for the centralized server. The research harnesses the power of other locally available mCloud and related devices that have more computational capability. Our experimental results demonstrate that with the number increasing of mCloud devices on the network, the percentage of encrypted data transmissions also increase since there are more chances to find a nearby secure device. Results further shows a decrease in the total response time from 0.6ms to 0.4ms utilizing the proposed distributed vs centralized system.

This research uses a statistical method to assess the efficiency and performance of Islamic and conventional banks. The Iraqi banks have been chosen as a case study in the period from 2006 to 2011. The data collected from, banks' financial reports, IMF database, the cost function and Seemingly Unrelated Regression were used to analyse the Iraqi bank's elasticity of substitution between inputs. It has been shown that the conventional banks in Iraq have better substitution than Islamic banks. In conclusion, the Islamic and conventional banks are exposed to a similar degree of risks, but different in nature; and the Islamic banks have less security than conventional banks to financial shocks. Since the Islamic banks cannot charge a fixed, predetermined return, and can't borrow from the financial market, so the Islamic banks could face more risk and volatile returns on their assets. The implication of that an excessive management modernization of Islamic banks is necessary to achieve a higher level of efficiency. This will give privilege for Islamic banks over the conventional bank. For conventional banks, they have to invent similar techniques to reduce cost and keep their position in the market.

To achieve real competition in the global market requires the manufacturers to have the ability to meet the needs and demands of their customers, which comes from the optimal planning of the supply chain. In this paper, consideration is given to the supply chain with multiproviders of raw materials, multimanufacturing locations, multi centres of selling products to customers in multiple, with instability (fuzzy) of customer demands, holding costs, costs of appointment, retire and training of workforce After building a mathematical model for the supply chain that aims to maximize the net profit and reduce all costs that include production costs, labour, raw materials, storage, transportation, and the cost shortage, the model was improved through a proposal that the decisionmaker has a desire to prefer one manufacturing location over another, as the proposal relied on developing a pairwise comparison in the Analytic Hierarchy Process (AHP) when the degree of comparison between factory locations is a fuzzy nature. The results of the proposed model were applied to actual data taken from an industrial organization.

This paper introduces a combination of three methods including a modified RSA cryptography, hidden text using steganography, and selection of random pixel from image to improve the general security level of the system. In this regard, the image is a carrier of the information transmitted through the media, and the fluid motion image is used to hide the information after it was encoded using modify RSA technique that before hiding it in a random way, because the image of fluid motion possesses the sinusoidal waves and turbulent motion. In this paper, a combination of three techniques is utilized in order to prevent the intruders and attackers from detecting the information and sharing it with others. LSB technique is used for hiding the message in imagebased steganography. In addition, pseudo number to choose the random number of pixel when hiding the message after encryption. Four measures including Peak Signal to Noise Ratio (PSNR), Mean Squared Error (MSE), Structural Similarity Index Measure (SSIM), and histogram are used to compare the original image and stegoimage. The results demonstrated the outperformance of the proposed method so that neither the attacker nor the intruder could discover the information contained within the image, due to the large value of the PSNR, very small value of the MSE, stability of the SSIM, and matching the histograms.

For any two entire functions $f$, $g$ defined on finite complex plane $mathbb{C}$, the ratios $frac{M_{fcirc g}(r)}{M_{f}(r)}$ and $frac{M_{fcirc g}(r)}{M_{g}(r)}$ as $rrightarrow infty $ are called the growth of composite entire function $fcirc g$ with respect to $f$ and $g$ respectively in terms of their maximum moduli. Several authors have worked about growth properties of functions in different directions. In this paper, we have discussed about the comparative growth properties of $fcirc g$, $f$ and $g,$ and derived some results relating to the generalized order $(alpha ,beta )$ after revised the original definition introduced by Sheremeta, where $alpha ,$ $beta $ are slowly increasing continuous functions defined on $(infty,+infty )$. Under different conditions, we have found the limiting values of the ratios formed from the left and right factors on the basis of their generalized order $(alpha ,beta )$ and generalized lower order $(alpha,beta ),$ and also established some inequalities in this regard.

A hybrid semisupervised boosting to sentiment analysis
https://ijnaa.semnan.ac.ir/article_5315.html
10.22075/ijnaa.2021.23334.2522
1
In this article, we propose a hybrid semisupervised boosting algorithm to sentiment analysis. Semisupervised learning is a learning task from a limited amount of labeled data and plenty of unlabeled data which is the case in our used dataset. The proposed approach employs the classifier predictions along with the similarity information to assign label to unlabeled examples. We propose a hybrid model based on the agreement among different constructed classification model based on the boosting framework to assign a final label to unlabeled data. The proposed approach employs several different similarity measurements in its loss function to show the role of the similarity function. We further address the main preprocessing steps in the used dataset. Our experimental results on realworld microblog data from a commercial website show that the proposed approach can effectively exploit information from the unlabeled data and significantly improves the classification performance.

Implementation of hybrid cryptographic schemes in a cloud environment for enhanced medical data security
https://ijnaa.semnan.ac.ir/article_5316.html
10.22075/ijnaa.2021.5316

Nowadays, several security architectures in cloud computing were employed in several applications, but they failed to secure the cloud data entirely. The current approaches use the ensemble algorithm for the decryption and encryption purpose to enhance the security technique. The input medical dataset is usually raw and might contain redundant packets and missing values. Initially, the data is preprocessed by means of the normalization technique. By using Enhanced Principal Component Analysis (EPCA) method, various attributes of the data can be obtained. After the extraction process, the classification mechanism is carried out for recognizing the attacks. The attack is predicted and is classified by means of the Adaptive AlexNet CNN classifier algorithm. A hybrid cryptographic technique in a cloud environment for improving the security rate and providing privacy preservation of the medical data in the cloud environment is presented. The proposed work mainly concentrates mostly on implementing hybrid cryptographic schemes which include AES algorithm, enhanced honeypot algorithm, SHA3 hashing and OTP in the cloud environment. It enhances the security of the data to a great extent. Thus, the presented technique is secured effectively that makes the intruders difficult to access the system as they need to attain control over servers.

We will add new types of modules over a ring $mathfrak{R}$ called $mathit{g}$ small completely stable module and $mathit{g}$ small duo module, assuming $mathfrak{R}$ is a ring with identity and $mathcal{M}$ is a unitary left $mathfrak{R}$module. We also present the $mathit{g}$ small dual stable module, which is a duality. We show that our new ideas have characterization and a few properties.

We consider the following twodimensional differential system: [ left{begin{array}{l} dot{x}=ax^{2}+bxy+cy^{2}+Phi(x,y) ,, \ dot{y}=dx^{2}+exy+fy^{2}+Psi(x,y) ,, end{array} right.] in which $lim_{(x,y)rightarrow(0,0)}frac{Phi(x,y)}{x^{2}+y^{2}} = lim_{(x,y)rightarrow(0,0)}frac{Psi(x,y)}{x^{2}+y^{2}}=0$ and $Delta=(afcd)^{2}(aebd)(bfce)neq0 $. By calculating Poincare index and using Bendixson formula we will find all the possibilities under definite conditions for classifying the system by means of kinds of sectors around the origin which is an equilibrium point of degree two.

Assume that $X$ is a subset of the finite group $G$. The A4graph is known as a simple graph denoted by $ mathcal{A}_4 (G, X) $ having $X$ as a vertex set and two vertices $ x, y in X,$ is linked by an edges if $ xneq y $ and $ {xy}^{1} = {yx}^{1} $. In this paper, we consider $ mathcal{A}_4 (G, X) $ when $G$ is either Tits group T or Mathieu group $M_{20}$ and $X$ is $G$conjugacy class of elements of order three. Valuable results reached, for example, disc structure, girth, clique number, and diameters of the A4graph.

A mathematical model for scheduling of transportation, routing, and crossdocking in the reverse logistics network of the green supply chain
https://ijnaa.semnan.ac.ir/article_5325.html
10.22075/ijnaa.2021.5325

Crossdocking refers to the practices of unloading materials from inbound vehicles and then loading them directly into outbound ones. Removing or minimizing warehousing costs, space requirements, as well as inventory utilization, crossdocking simplifies supply chains and makes them deliver goods to markets in a faster and more efficient manner. Accordingly, a mixedinteger linear programming ($MILP $) model is developed in the present study to schedule transportation routing and crossdocking in a reverse logistics network ($RLN$). Furthermore, different traffic modes are also considered to reduce fuel consumption, which reduces emissions and pollution. The proposed model is a multiproduct, multistage, and nondeterministic polynomialtime that is an NPhard problem. We use the nondominated sorting genetic algorithm II ($NSGAII$) to solve the model. A numerical example has been solved to illustrate the efficiency of the method.

In this article, we have designed a novel 4:2 QCA Compressor with a nonlinear effect. This can be considered as a new vision to design approximate Majority circuits with more than fiveinput. The main advantages of these ideas are the reduced number of QCA cells as well as power dissipation, increased speed, and improved cell area In addition, a novel hierarchy is introduced to optimize digital systems. The 4:2 Compressor circuit is selected as a benchmark. This circuit is simulated with some technologies such as CMOS, CNT, and QCA in different architectures. All results from power respective were compared. We have used QCADesigner and QCAPro for QCA Circuits, Hspice with 20nmnfet PTMMG model for CMOS circuits and Stanford CNFET 20nm model for CNT circuits as simulation tools to evaluate circuits.

https://ijnaa.semnan.ac.ir/article_5327.html
10.22075/ijnaa.2021.23400.2531

In this paper, we develop the notion of $(psi, F)$contraction mappings introduced in cite{wad1} in $b$metric spaces. To achieve this, we introduce the notion of generalized multivalued $(psi, S, F)$contraction type I mapping with respect to generalized dynamic process $D(S, T, x_0),$ generalized multivalued $(psi, S, F)$contraction type II mapping with respect to generalized dynamic process $D(S, T, x_0),$ and establish common fixed point results for these classes of mappings in complete $b$metric spaces. As an application, we obtain the existence of solutions of dynamic programming and integral equations. The results presented in this paper extends and complements some related results in the literature.

The purpose of this article is to introduce the notion of an $mathfrak{A}$meter, as an operatorvalued distance mapping on a set $X$ and investigating the theory of $mathfrak{A}$metric spaces, where $mathfrak{A}$ is a noncommutative $C^*$algebra. We demonstrate that each metric space may be seen as an $mathfrak{A}$metric space and that every $mathfrak{A}$metric space $(X,delta)$ can be regarded as a topological space $(X,tau_{delta})$.

In this paper, the time series data for the number of deaths from Coronavirus (COVID19) patients in Iraq were analyzed for the period from 4/3/2020 to 18/2/2021. ARCH, GARCH, and TGARCH models were applied due to the changing volatility of the series leading to a heteroscedastic variance. The appropriate models for the series were diagnosed and the best model was chosen and used for forecasting by the exponential smoothing methods. The comparison criterion used was the Root Mean Squared Error and the Sum of Squared Residuals. The most appropriate model for modeling and forecasting the Coronavirus deaths series in Iraq was diagnosed as TGARCH (1,1). Finally, the method of Holtwinteradditive forecasting was the best method among the

This paper deals with comparing three different estimators of fuzzy reliability estimator of one scale parameter Rayleigh distribution were first of all the one scale parameter Rayleigh is defined. Afterwards, the cumulative distribution function is derived, as well as the reliability function is also found. The parameters θ is estimated by three different methods, which are maximum likelihood, and moments, as well as the third method of estimation which is called percentile method or Least Square method, where the estimator $(hat{vartheta}_{pec})$ obtained from Minimizing the total sum of the square between given C DF, and one nonparametric estimator like $hat{F}(ti,theta)=frac{i}{n+1}$ after the estimator of $(theta)$, which $(hat{theta})$ is obtained. We work on comparing different fuzzy reliability estimators and all the results are explained besides different sets of taking four sample sizes $(n= 20, 40, 60, and 80)$.

https://ijnaa.semnan.ac.ir/article_5342.html
10.22075/ijnaa.2021.5342

The purpose of this study is to determine if it is possible to use the class of $delta_g$close sets and $delta$closed sets to find a new class of close sets, namely $iidelta_g$close sets and $iidelta$close sets. We use these new classes to arrive at the separation axiom, which is the separation axiom of $iiT_{3/4}.$ We also use the properties of $delta hat{g}$closed sets to find new class of close sets, namely $iidelta hat{g}$closed set. We use it to create a new type of separation axiom. The study found new closed sets, namely: $iidelta hat{g}$closed sets is introduced for topological space. We will also prove that category falls between the class of $iidelta$closed set and the class of $iigs$closed set. As well study the relationship between it and other closed sets, such as the closed set of type $iigs$ as well as the closed set of type $iig$, and then, through these closed sets, we will study new types of the axiom of separation, which are $ ii T_{3/4}$ space and $ ii hat{T}_{3/4}$ space, and also clarify the relationship between the axiom of separation, and some of the closed and open sets previously studied. The study also included the relationship between the axiom of separation, of type $iiT_{1/2}$ space and $ii T_{3/4}$ space as well as the axiom of separation of type $ii T_{3/4}$ space and $ ii hat{T}_{3/4}$ space. The study included some important proofs. The study also included a chart, showing the relationship between closed sets of types that were studied and can be used.

In this article, we extended an efficient computational method based on Walsh operational matrix to find an approximate solution of fractional diffusion equations, First, we present the fractional Walsh operational matrix of integration and differentiation. Then by applying this method, the Fractional diffusion equations are reduced into a system of an algebraic equation. The benefits of this method are the low cost of setting up the equations without applying any projection method such as collocation, Galerkin, etc. The results show that the method is very accurate and efficient.

Epidemiological model Involving Two Diseases in Predator Population with Holling TypeII Functional Response
https://ijnaa.semnan.ac.ir/article_5349.html
10.22075/ijnaa.2021.5349

In this paper, two types of diseases in the predator population in an ecological model are proposed and analyzed. The first (SIS infectious disease) transmitted horizontally, spread by contact between susceptible individuals and infected individuals. And the second (SI disease) is transmitted vertically from mothers to offspring with the effect of an external source (environmental effect). No transmission of the diseases can happen from predator to prey by predation or contact. Linear functional response and Holing typeII for describing the predation of the susceptible and the infected predators respectively also linear incidence for describing the transition of diseases are used. All possible equilibrium points were analyzed for this model. Locally and globally dynamics of the model have been discussed, numerical simulation is used to investigate the effect of the diseases on the system’s dynamics.

On first excess level analysis of hysteretic bilevel control queue with multiple vacations

10.22075/ijnaa.2021.5354

In this article, we consider queueing model with bilevel hysteretic control and multiple vacations. This system's mechanism depends on the queue size and the facility where the server goes to the series of vacation trips when the line is empty and returns but waiting in the system when the number of units is more than level (M). In this case, the server doesn't start a new busy period unless this size is more than another level (N > M). Furthermore, we employ Npolicy and first excess level analysis to derive the probability generating function of queue size. Additionally, we assume that the vacation times are exponentially distributed random variables, and arrival batches are type 1 geometrically distributed random variables.

Several scientific and engineering applications are usually described as integral equations. We propose a numerical approach for solving the type of Fredholm nonlinear boundary value problems in a finite domain. The paper aims to use the qhomotopy analysis method to estimate the solution to test the efficiency of the proposed method. Comparison with updated work is exacted. The obtained results show that the proposed method is very effective and convenient for nonlinear Fredholm integral equations. The interval of convergence of homotopy analysis method, if exists, is increased when using qhomotopy analysis method is more to converge. The result reveals that the q homotopy analysis method is considered a good method for solving NFIES.

Reducing explicit word vectors dimensions using BPSObased labeling algorithm and voting method
https://ijnaa.semnan.ac.ir/article_5363.html
10.22075/ijnaa.2021.5363

Interpretability of word vector components is very important for obtaining conceptual relations. Word vectors derived from counting models are interpretable but suffer from the highdimensionality problem. Our goal in this study is to obtain interpretable lowdimensional word vectors in such a way that the least accuracy loss occurs. To achieve this goal, we propose an approach to reduce the dimensions of word vectors using a labeling method based on the BPSO algorithm and a voting method for selecting final context words. In this approach, we define several different base models to solve the labeling problem using different data and different objective functions. Then, we train each base model and select 3 of the best solutions for each model. We create the target word vectors of the dictionary based on the context words labeled "1". Next, we use the three best solutions of each base model to build the ensemble. After creating the ensemble, we use the voting method to assign the final label to the primary context words and select N final context words. In this study, we use the corpus ukWaC to construct word vectors. We evaluate the resulting word vectors on the MEN, RG65, and SimLex999 test sets. The evaluation results show that by reducing the word vectors dimensions from 5000 to 1507, the Spearman correlation coefficient of the proposed approach has been reduced to a lesser extent compared to each base model. Therefore, the accuracy drop of the proposed approach is justified after reducing the dimensions from 5000 to 1507. It is not a large penalty because the resulting word vectors are lowdimensional and interpretable.

The Internet has become one of the most important daily social, financial and other activities. The number of customers who use the Internet to conduct their business and purchases is very large. This results in billions of dollars being transferred every day online. Such a large amount of money attracts the attention of cybercriminals to carry out their illegal activities. “Fraud” is one of the most dangerous of these methods, especially phishing, where attackers try to steal user credentials using fraudulent emails, fake websites, or both. The proposed system in this paper includes efficient data extraction from the web file through data collection and preprocessing. and web usage mining procedure to extract features that demonstrate user behavior. And featureextracting URL analysis to detect website phishing addresses. After that, the features from the above two parts are combined to make the number of features sixtythree. Finally, a classification algorithm (Random Forests) is applied to determine if website addresses are phishing or legitimate. Suggested algorithms performance is determined by using a confusion matrix that shows the robustness of the proposed system.

In this paper, an analysis is conducted on the data transmitted through the edge computing technique. The research creates a trust model that establishes direct, indirect, and mutual trust between the source and destination blocks when data is sent. That is, the study integrated blockchain as a model to transmit the data in a secured way through the blockchains, however, the intrusion in blockchains can be avoided based on trust based model. The simulation is conducted on various testbeds and with existing blockchain mechanisms. The findings reveal that the suggested trustbased paradigm is successful at safeguarding data sent over the edge.

Intrusion detection in computer networks using a cost sensitive ensemble classifier
https://ijnaa.semnan.ac.ir/article_5369.html
10.22075/ijnaa.2021.5369
1
The growing use of Internet technology and the attack on computer networks have made intrusion detection systems an essential part of computer security. Conventional intrusion control methods such as firewalls or access control systems are no longer alone able to withstand attacks. Therefore, the need to detect new attacks and anomalies is inevitable. The dataset used in this paper is called NSLKDD which includes 5 classes: one of them is normal and the other four classes are attacks. In the presented work, an ensemble classifier based on the mean probability of attacks is adopted. The true detection rate of the proposed system is $99.89%$ which is more than other competing methods. Moreover, the ensemble classifier achieved an F1measure of $92.48%$. To improve the F1 measure, we used a metaclassifier called metacost which incorporates a cost matrix to transform the original classifier into a costsensitive classifier. By this idea, we achieved an F1measure of $94.1%$ which outperforms than noncost sensitive ensemble classifier. These results show that the proposed system can be used as a suitable defence tool to detect intrusion against cyberattacks.

The impact of alternative resources and fear on the dynamics of the food chain
https://ijnaa.semnan.ac.ir/article_5370.html
10.22075/ijnaa.2021.5370
1
In this paper, a threespecies food chain model is proposed and studied. It is assumed that there are fear costs in the first twolevel due to predation risk and there exists an alternative source of food for a top predator. Holling’s disc function is adopted to describe the food transition throughout the chain. All the solution properties are discussed. The conditions of local stability and persistence of the model are established. The Lyapunov function is used to specify the basin of attraction for each equilibrium. Local bifurcation analyses are studied. The global dynamics of the model are investigated numerically. Different bifurcation diagrams and attractors are obtained. It is obtained that the system is rich in dynamics that include chaos.

This work aims to analyze a threedimensional discretetime biological system, a preypredator model with a constant harvesting amount. The stage structure lies in the predator species. This analysis is done by finding all possible equilibria and investigating their stability. In order to get an optimal harvesting strategy, we suppose that harvesting is to be a nonconstant rate. Finally, numerical simulations are given to confirm the outcome of mathematical analysis.

Forecasting enhancement using a HodrickPrescott filter

Sound forecasts are essential elements of planning, especially for dealing with seasonality, sudden changes in demand levels, strikes, large fluctuations in the economy, and pricecutting manoeuvres for competition. Forecasting can help decisionmakers to manage these problems by identifying which technologies are appropriate for their needs. The proposal forecasting model is utilized to extract the trend and cyclical component individually through developing the HodrickPrescott filter technique. Then, the fit models of these two real components are estimated to predict the future behaviour of electricity peak load. Accordingly, the optimal model obtained to fit the periodic component is estimated using spectrum analysis and the Fourier model, and the expected trend is obtained using simple linear regression models. Actual and generation data were used for the performance evaluation of the proposed model. The results of the current model, with improvement, showed higher accuracy as compared to ARIMA model performance.

Suggested methods for prediction using semiparametric regression function

Ferritin is a key organizer of protected deregulation, particularly below risky hyperferritinemia, by straight immunesuppressive and proinflammatory things. We conclude that there is a significant association between levels of ferritin and the harshness of COVID19. In this paper, we introduce a semiparametric method for prediction by making a combination of NN and regression models. So, two methodologies are adopted, Neural Network (NN) and regression model in designing the model; the data was collected from a nursing home hospital for period 11/7/2021 23/7/2021, the sample size is 100 covid positive patients with 12 females & 38 males out of 50, while 26 female & 24 male are nonCOVID out of 50. The input variables of the NN model are identified as the ferritin and a gender variable. The higher results precision is attained by the multilayer perceptron (MLP) networks when we applied the explanatory variables as the inputs with one hidden layer, which covers 3 neurons, as the planned many hidden layers are with one output of the fitting NN model which is used in stages of training and validation beside the actual data. We used a portion of the actual data to verify the behavior of the developed models, we find out that only one observation is a false predictive value. This means that the estimation model has significant parameters to forecast the type of Covid cases (Covid or no Covid).

A proposed method for cleaning data from outlier values using the robust RFCH method in structural equation modeling
https://ijnaa.semnan.ac.ir/article_5374.html
10.22075/ijnaa.2021.5374

The GLS and ML methods are the most common methods for estimating SEM but require multivariate normality. Therefore, methods robust to standard errors and quality of fit indexes to Chisquare have been proposed: MLR and they are considered superior to ML and GLS methods analyzing ordinal data. When we have a fiveway Likert scale, the data is treated as continuous by calculating the covariance matrix as inputs for ML, GLS, and MLR. However, outliers are familiar because modeling requires a large sample size, either because of the input of data or answers more than is expressed within a particular category. Their presence affects even methods with robust corrections, where the accuracy of estimating parameters, standard errors, and fit indicators may be compromised the quality of fit indexes and inappropriate solutions, where a robust algorithm is proposed to clean the data from the outlier, as this proposed algorithm calculates the robust correlation matrix robust RFCH Reweighted Fast Consistent and High Breakdown, which consists of several steps and has been modified by taking the clean data before calculating the robust RFCH correlation matrix. It was also suggested to make a comparison between the three methods before the treatment process with the presence of outlier values and note the extent of their impact on the methods and after using the robust RFCH method, and note the extent of improvement in estimations, standard errors and the overall quality of fit indexes for each of the Chisquare index, CFI, TLI, and RMSEA, SRMR and CRMR, with the robust corrections in the Chisquare index for each of the methods MLR. Through the simulation experiment, the researcher reached the power of the proposed method robust RFCH in improving the quality of parameter estimation, standard errors, and overall fit indexes quality.

The hearingimpaired community uses gestures to communicate. Gestures can also be used in interactions between man and computer. However, gestures become increasingly complicated in a comparatively complex environment. A recognition algorithm with a choice of function based on the improved genetic algorithm is proposed to improve the ability to identify gestures. The recognition process includes retailing, extraction, and feeding functions before classifying the neural network. After learning gestures, the proposed method is compared with traditional methods that use the classic genetic algorithm. The proposed method demonstrates the effect of optimization and sensitivity of the function.

Energy Aware Multi Objective Algorithm for Task Scheduling on DVFSEnabled Cloud Datacenters using Fuzzy NSGAII
https://ijnaa.semnan.ac.ir/article_4666.html
10.22075/ijnaa.2020.21625.2283

Nowadays, energy consumption is curtailed in an effort to further protect the environment as well as to avoid service level agreement (SLA) breach, as critical issues in task scheduling on heterogeneous computing centers. Any reliable task scheduling algorithm should minimize energy consumption, makespan, and cost for cloud users and maximize resource utilization. However, reduction of energy consumption leads to larger makespan and decreases load balancing and customer satisfaction. Therefore, it is essential to obtain a set of nondomination solutions for these multiple, conflicting objectives, as a nonlinear, multiobjective, NPhard problem. This paper formulates the energy efficient task scheduling in green data centers as a multiobjective optimization problem so that fuzzy Nondominated Sorting Genetic Algorithm 2 (NSGAII) has been applied using the concept of Dynamic Voltage Frequency Scaling (DVFS). In this procedure, we adopted fuzzy crossover and mutation for optimal convergence of initial solutions. For this purpose, the binary variance function of gene values and the mean variance function of objective values are proposed for fuzzy control of mutation rate, increasing the variation in the optimal Pareto front as well as the correct frequency variance function of the processors engaged in scheduling to control the crossover rate. This serves to add the objective of indirect load balancing to the optimization objectives, thereby to replace the threeobjective optimization process with fourobjective optimization. In the experiments, the proposed NSGAII with fuzzy algorithm is compared against the NSGAII algorithm, involving three scheduling strategies namely Green, Time and Cost Oriented Scheduling Strategy. The simulation results illustrate that the newly method finds better solutions than others considering these objectives and with less iteration. In fact, the optimal Pareto solutions obtained from the proposed method improved the objectives of makespan, cost, energy and load balance by 4%, 17%, 1% and 13%, respectively.

This paper is primarily committed to three primary angles concerning photovoltaic based DG. The fundamental perspective being the reduction of influence changes in daylight based photovoltaic and the Reduction of influence distribution in the framework of the system. According to the unpredictable changes credited to the wide range of sun situated radiations. Further, the sizing related issues and region of an SPV based DG may cause a ton of influence concerns effecting the overall DG system operation and its efficiency. The second region of concern is the method used in the control of the DG and its feasibility to diminish framework influence issues. Another area of concern is network interconnection, through the appropriate introduction of RES into the ordinary grid for supportable and stable activity. This has been managed through an extensive contextual analysis of an operational system.

Hybrid encryption using playfair and RSA cryptosystems
https://ijnaa.semnan.ac.ir/article_5379.html
10.22075/ijnaa.2021.5379

The security is demanded to transport important data over the network. In this work a hybrid encryption depending on playfair cipher and RSA algorithm is proposed to give more confidentially and get rid of the defects of the two methods. The first cipher text is obtained by playfair cipher by using (812) expanded key matrix that is filled by decimal ASCII characters of Alphabets, numbers and common characters of ASCII table while the final cipher text is obtained by RSA cryptosystem by applying it for blocks of two characters. The proposed hybrid encryption avoids to take large numbers in RSA algorithm and performs complex operations that need a long time to do. The proposed hybrid cipher is tight security that is difficult to analyze and detect from hackers and intruders.

Automated prediction of endometriosis using deep learning
https://ijnaa.semnan.ac.ir/article_5383.html
10.22075/ijnaa.2021.5383
1
Endometriosis is the anomalous progress of cells at the outer part of the uterus. Generally, this endometrial tissue stripes the uterine cavity. The existence of endometriosis is identified through procedures known as Transvaginal Ultra Sound Scan (TVUS), Magnetic Resonance Imaging (MRI), Laparoscopic procedures, and Histopathological slides. Minimal Invasive Surgery (MIS) Laparoscopic images are recorded in a small camera. To assist the surgeon in identifying their presence of endometriosis, image quality (characteristics) was enhanced for more visual clarity. Deep learning has the ability in recognising the images for classification. The Convolutional Neural Networks (CNNs) perform classification of images on large datasets. The proposed system evaluates the performance by a novel approach that implements the transfer learning model on a wellknown architecture called ResNet50. The proposed system train the model on ResNet50 architecture and yielded a training accuracy of 91%, validation accuracy of 90%, precision of 83%, and recall of 82%, which can be applied for larger datasets with better performance. The presented system yields higher Area Under Curve (AUC) of about 0.78. The proposed method yields better performance using ResNet50 compared to other transfer learning techniques.

Nowadays, information security has become a very important and difficult matter. Security cameras are widespread in banks, ATMs, airports, universities, offices, and anywhere with a security system. The face recognition process is one of the most demanding image analysis and computer vision tasks. Faces are biometric systems that utilized a digital image of a person to identify or authenticate that person. This system is employed in the field of security. The face recognition system is required to detect and recognize the face in the image automatically. It works by extracting and then recognizing its attributes, irrespective of expression or illumination, transitions (translation, rotation and scaling of the image) and ageing, which is a difficult task. The proposed system records the facial features of the person standing in front of the camera, such as the size, position of the nose, eyes, jawbones, and cheekbones structure. This program also allows the user to evaluate and analyze the image. This system does not require long training for technicians because it is easy to use and gives quick and accurate results compared to biometric techniques the other. It is worth noting that Matlab roll was used in the design of this program.

Design and simulation of optical logic gates based on insulator  metal – insulator (IMI) plasmonic waveguides for optical communications
https://ijnaa.semnan.ac.ir/article_5392.html
10.22075/ijnaa.2021.5392

In this study, a structure has been proposed implementing the optical Plasmonic logic gates (OR, NOR, AND, NAND, NOT) using the linear Plasmonic waveguide and the double ring resonator. The results of these gates were analyzed and simulated by means of Comsol Multiphysics (5.6) using Finite Element Analysis (2FEM). These gates were implemented in the same structure depending on the characteristic of constructive and destructive optical interference between the signals propagating in the input ports and the control port, the phase and direction of those signals, as well as the positions of these ports. Hence, the performance of these gates was measured according to two criteria, first, the optical transmission ratio and the second, the contrast ratio, which is the ratio between the transmitter ON state of logic (1) and OFF for logic (0).

Strategies and challenges of implementing social responsibilities based on compliance auditing banking services to stakeholders and its effect on reducing the gap between expectations
https://ijnaa.semnan.ac.ir/article_5398.html
10.22075/ijnaa.2021.5398

This study aimed to identify strategies for implementing social responsibility in banking services to stakeholders considering the compliance auditing and determine barriers. The Grounded Theory was used to develop the model, and banking experts were interviewed using a purposive sampling method to collect qualitative data. A total of 336 certified public accountants were selected in the quantitative part using a random sampling method. A questionnaire was used for data collection, and the analysis of variance (ANOVA) and ttest and Friedman test were used to analyze the data. The essential executive strategies were to increase welfare services proportional to the inflation rate to employees, implement a meritocracy system in the banking system, accept the workforce with government testing and supervision, increase actual stock returns and distributive profits, provide transparent, timely, and reliable information with simultaneous access for all, development of electronic banking, and justice in equal services to all customers with high quality and speed. In addition, the critical barriers were the lack of prioritizing compliance with social responsibilities at the top of organizational goals and the private or public nature of banks. Considering the confirmation of the five hypotheses, the compliance with social responsibilities in customer service had the most significant effect, and the other stakeholders service had the least effect in reducing the stakeholders’ expectation gap.

Organizational entrepreneurship barriers in sport organizations (IRI. Gymnastics Federation)
https://ijnaa.semnan.ac.ir/article_5420.html
10.22075/ijnaa.2021.5420
1
This paper aimed to identify the organizational entrepreneurship barriers of the Gymnastics Federation of the Islamic Republic of Iran. The mixed method and Brown and Clark method were used in the research. The population consisted of two sections, including gymnastics experts and university professors (180 people), and the sample size was 16 people based on the theoretical saturation index and 120 people based on the Cochran formula. Three structural 14, behavioral 13, and contextual barriers with 5 indicators were identified by qualitative data analysis. The research instrument in the quantitative part was a questionnaire that was extracted from the codes of the qualitative part using LISREL and SPSS software. The results confirmed the items and factors in the first and second confirmatory factor analysis tests. Three barriers were identified, and 32 indicators were obtained as the measurement tool. The model was fitted using the structural equation method (SEM) based on path coefficient and tstatistic. The effect of three independent variables was significant (1.00, 0.90, and 0.97), indicating the model’s high estimation power. The results showed that underlying barriers had the most significant effect on the failure of organizational entrepreneurship.

Energy efficient Q learning based Kullback sparse encoder for traffic and congestion control data delivery in WSN
https://ijnaa.semnan.ac.ir/article_5440.html
10.22075/ijnaa.2021.5440
1
In dense traffic Wireless Sensor Network (WSN), traffic congestion can increase routing overhead and packet loss, which restricts the entire network performance, therefore a trafficaware and congestioncontrol data delivery is required to control the traffic. The proposed Energyefficient Qlearning and Kullback Sparse Encoder (EQKSE) method is used for trafficaware routing and congestioncontrol data delivery method for WSN. The method enforces a traffic balancing strategy using the energyefficient reward function and estimates the wireless link quality by the Energyefficient and QLearning Routing algorithm. On the basis of the estimation of each wireless link, the Energyefficient QLearning based Trafficaware Routing model makes routing decisions through energy and queue length to reduce routing overhead and time significantly. With the obtained optimal routes data aggregation are performed at the sink node, causing a proportionate amount of congestion. To handle this issue, a Kullback Leibler Sparse Auto Encoder (KLSAE) Congestioncontrol Data Delivery method is proposed. This KLSAE model with the aid of the reconstruction loss function, through divergence reduces the congestion, therefore contributing to packet loss, and packet delivery ratio. Simulation results show that EQKSE method performs trafficaware routing by minimizing both the route selection time and overhead. In high node density scenarios, it also betters the stateoftheart methods in packet delivery ratio and packet loss rate.

In this article, first we introduce six types of power graphs related to a graph (or directed graph), with the help of set theory.Then we show that these newly defined power graphs are pairwise distinct by a few examples. Finally, we discuss the relation between Eulerian being the base graph and these six power graph types. Moreover, we express the relation between pairwise Eulerian of these power graphs.
