In this paper, a realtime denoising filter based on modelling of stable hybrid models is presented. The hybrid models are composed of the shearlet filter and the adaptive Wiener filter in different forms. The optimization of various models is accomplished by the genetic algorithm. Next, regarding the significant relationship between Optimal models and input images, changing the structure of Optimal models for image denoising is modelled by the ANFIS. The eight hundred digital images are used as train images. For eight hundred training images, Sixty seven models are found. For integrated evaluation, the amounts of image attributes such as Peak Signal to Noise Ratio, Signal to Noise Ratio, Structural Similarity Index, Mean Absolute Error and Image Quality Assessment are evaluated by the Fuzzy deduction system. Finally, for the features of a sample noisy image as test data, the proposed denoising model of ANFIS is compared with wavelet filter in 2 and 4 level , Fast bilateral filter, TVL1, Median, shearlet filter and the adaptive Wiener filter. In addition, run time of proposed method are evaluated. Experiments show that the proposed method has better performance than others.

In this work, we consider variable order difusion and wave equations. The derivative is described in the Caputo sence of variable order. We use the Genocchi polynomials as basic functions and obtain operational matrices via these polynomials. These matrices and collocation method help us to convert variable order diffusion and wave equations to an algebraic system. Some examples are given to show the validity of the presented method.

A new technique of reduce differential transform method to solve local fractional PDEs in mathematical physics
https://ijnaa.semnan.ac.ir/article_4653.html
10.22075/ijnaa.2021.4653

In this manuscript, we investigate solutions of the partial differential equations (PDEs) arising in mathematical physics with local fractional derivative operators (LFDOs). To get approximate solutions of these equations, we utilize the reduce differential transform method (RDTM) which is based upon the LFDOs. Illustrative examples are given to show the accuracy and reliable results. The obtained solutions show that the present method is an efficient and simple tool for solving the linear and nonlinear PDEs within the LFDOs.

A metaheuristic clustering method to reduce energy consumption in Internet of things
https://ijnaa.semnan.ac.ir/article_4657.html
10.22075/ijnaa.2021.4657
1
The Internet of Things (IoT) is an emerging phenomenon in the field of communication, in which smart objects communicate with each other and respond to user requests. The IoT provides an integrated framework providing interoperability across various platforms. One of the most essential and necessary components of IoT is wireless sensor networks. Sensor networks play a vital role in the lowest level of IoT. Sensors in sensor networks use batteries which are not replaceable, and hence, energy consumption becomes of great importance. For this reason, many algorithms have been recently proposed to reduce energy consumption. In this paper, a metaheuristic method called whale optimization algorithm(WOA) is used to clustering and select the optimal cluster head in the network. Factors such as residual energy, shorter distance, and collision reduction have been considered to determine the optimal cluster head. To prove the optimal performance of the proposed method, it is simulated and compared with three other methods in the same conditions. It outperforms the other methods in terms of energy consumption and the number of dead nodes.

Linkage factors optimization of multioutputs of compliant mechanism using response surface
https://ijnaa.semnan.ac.ir/article_4658.html
10.22075/ijnaa.2021.4658
1
This paper presents a linkage factors synthesis and multilevel optimization technique for bistable compliant mechanism. The linkage synthesis problem is modeled as multiple level factors and responses optimization problem with constraints. The bistable compliant mechanism is modeled as a crank slider mechanism using pseudorigidbody model (PRBM). The model exerts the large deflection of flexible element which explains compliant mechanism’s bistable performance. The design concept is applied on variable input parameters subsets. Though the effect of compliant mechanism process factors on Fmax and PRBM deflection angle (Thetacap Θ1) are contradictory when studied individually as no response gives best process quality. The relationship model between input factors and responses characteristics were generated by ANOVA and optimized by response surface methodology (RSM). ANOVA shown more significant factors are the initial angle of link1 (θ1) and material thickness (t). The BoxBehnken design of RSM is applied with a desirability function approach to determine the optimum set of parameters for minimizing Fmax and maximizing the Thetacap (Θ1). Thus, this technique shown flexibility based on the product application could be tested and established.

Excellence of financial reporting information and investment productivity
https://ijnaa.semnan.ac.ir/article_4659.html
10.22075/ijnaa.2021.4659
1
Objective –This study intends to examine the relationship between investment efficiency and financial information excellence. The study is also examining the moderating impact of sustainability on the relation between excellence in financial information and investment productivity. Methodology –The cumulative measurements are 668 firmyears and are made up of 257 subsamples of underinvestment and 411 subsamples of overinvestment. This study may find no proof on the moderating effect of diversification on the relation between excellence in financial information and efficiency in investment. In the years 2016 to 2019, our samples are companies listed on the Dhaka Stock Exchange. Findings – The results indicate that financial information reporting quality (both for overinvestment and underinvestment subsamples) has a positive association with investment performance. Although the evidence is not consistent across subsamples, the test findings on the relationship between diversification and efficiency of investment appear to indicate a negative and substantial relationship between diversification and efficiency of investment. Research limitations/implications – The study finds no research investigating financial information quality and the productivity of investments. Moreover, it also discusses the regulating consequence for diversification on the correlation concerning financial knowledge and productivity of investment, which has not been examined in current studies as well. Originality/value – This research fills a void in the literature by providing understandings into performs followed by Bangladeshi companies in diversification effects in investment productivity.This study also has major consequences in providing additional proof of the connection between financial information and productivity of investment.

Automatic QoSaware web services composition based on setcover problem
https://ijnaa.semnan.ac.ir/article_4664.html
10.22075/ijnaa.2021.4664
1
By definition, webservices composition works on developing merely optimum coordination among a number of available webservices to provide a new composed webservice intended to satisfy some users requirements for which a single web service is not (good) enough. In this article, the formulation of the automatic webservices composition is proposed as several setcover problems and an approximation algorithm has been exploited to solve them. In proposed method, the webservice composition has been carried out within two main phases, the topdown expansion of the composition tree, and the production of composed service by bottomup traversal of composition tree. In the first phase, the production of a composition tree (similar to the production of tree in problemsolving by searching) is proposed by starting from the output or postconditions of the requested service towards its input or preconditions. Each node or state of the tree is a set of inputs and/or outputs or conditions, and services as tree edges illustrate the transition from one node to another. In the second phase, finding the path from the leaves of the produced composition tree to the root is considered equal to reaching the output of requested service, and this path specifies the involved services and the composition plan. The requested service input set determines the available leaves of the composition tree. To achieve each nonleaf node of the tree, a setcover problem is produced and solved using a greedy approximation algorithm. If the production and solving of the setcover problems continues hierarchically until it reaches the root node, the composition plan and cost of the required composition service will be specified. The main focus of this research is the joint sequential and parallel composition with the aim of producing nearoptimal and QoSaware composed services.

In this study two actual types of problems are considered and solved: 1) determining the maximum common connected fragment of the Ttree (Tdirected tree) which does not change with time; 2) determining all nonisomorphic maximum common connected fragments of the Ttree (Tdirected tree) which do not change with time. The choice of the primary study of temporal directed trees and trees is justified by the wide range of their practical applications. Effective methods for their solution are proposed. Examples of the solution of the problem for temporal trees and temporal directed trees are given. It is shown that the experimental estimates of the computational complexity of the solution for problems of the temporal directed trees and the temporal trees.

Numerical solution of second order IVP by fuzzy transform method
https://ijnaa.semnan.ac.ir/article_4748.html
10.22075/ijnaa.2020.21716.2289
1
In this paper, we employed fuzzy transforms to present a new method for solving the problem through secondorder fuzzy initial value. The advantage of the fuzzy transform method is that, unlike other methods (e.g. highorder fuzzy Taylor series), it does not require any higherorder derivative calculation, thus reducing computational cost. In two examples, the results of the newly proposed method were examined against several conventional methods, indicating the more desirable performance of the new method.

A robust optimization approach for a multiperiod locationarc routing problem with time windows: A case study of a bank
https://ijnaa.semnan.ac.ir/article_4752.html
10.22075/ijnaa.2019.16392.1868
1
A LocationArc Routing Problem (LARP) is a practical problem, while a few mathematical programming models have been considered for this problem. In this paper, a mixed nonlinear programming model is presented for a multiperiod LARP with the time windows under demand uncertainty. The time windows modeling in the arc routing problem is rarely. To the best our knowledge, it is the first time that the robust LARP model is verified and an optimal solution is presented for it. For this purpose, the CPLEX solver is used for solving the treasury location problems of a bank as a case study. These problems are nodebased with close nods and can be transformed into arcbased. Therefore, the method LRP and LARP models can be used to solve these problems. The comparing results of the LRP and LARP models prove that the LARP has a better performance regarding timing and optimal solution. Furthermore, comparing the results of deterministic and robust LARP models for this case study shows the validity of the robust optimization approach.

Deep inference: A convolutional neural networks method for parameter recovery of the fractional dynamics
https://ijnaa.semnan.ac.ir/article_4757.html
10.22075/ijnaa.2021.4757
1
Parameter recovery of dynamical systems has attracted much attention in recent years. The proposed methods for this purpose can not be used in realtime applications. Besides, little works have been done on the parameter recovery of the fractional dynamics. Therefore, in this paper, a convolutional neural network is proposed for parameter recovery of the fractional dynamics. The presented network can also estimate the uncertainty of the parameter estimation and has perfect robustness for realtime applications.

On the dynamics of a nonautonomous rational difference equation
https://ijnaa.semnan.ac.ir/article_4760.html
10.22075/ijnaa.2020.4760
1
In this paper, we study the following nonautonomous rational difference equation [ y_{n+1}=frac{alpha_n+y_n}{alpha_n+y_{nk}},quad n=0,1,..., ] where $left{alpha_nright}_{ngeq0}$ is a bounded sequence of positive numbers, $k$ is a positive integer and the initial values $y_{k},...,y_0$ are positive real numbers. We give sufficient conditions under which the unique equilibrium $bar{y}=1$ is globally asymptotically stable. Furthermore, we establish an oscillation result for positive solutions about the equilibrium point. Our work generalizes and improves earlier results in the literature.

Four step hybrid block method for the direct solution of fourth order ordinary differential equations
https://ijnaa.semnan.ac.ir/article_4762.html
10.22075/ijnaa.2021.4762
1
This paper proposes a direct fourstep implicit hybrid block method for directly solving general fourthorder initial value problems of ordinary differential equations. In deriving this method, the approximate solution in the form of power series is interpolated at four points, i.e $ x_n,,, x_{n+1},,x_{n+2},,x_{n+3} $ while its forth derivative is collocated at all grid points, i.e $ x_n, ,,x_{n+frac{1}{4}},,, x_{n+1} , ,,x_{n+2}, ,,x_{n+frac{5}{2}}, ,,x_{n+3}, ,,x_{n+frac{7}{2}} $ and $ x_{n+4} $ to produce the main continuous schemes. In order to verify the applicability of the new method, the properties of the new method such as local truncation error, zero stability, order and convergence are also established. The performance of the newly developed method is then compared with the existing methods in terms of error by solving the same test problems. The numerical results reveal that the proposed method produces better accuracy than several existing methods when solving the same initial value problems (IVPs) of second order ODEs.

In this paper, we prove some fixed points properties and demiclosedness principle for mean nonexpansive mapping in uniformly convex hyperbolic spaces. We further propose an iterative scheme for approximating a common fixed point of two mean nonexpansive mappings and establish some strong and $bigtriangleup$convergence theorems for these mappings in uniformly convex hyperbolic spaces. The results obtained in this paper extend and generalize corresponding results in uniformly convex Banach spaces, CAT(0) spaces and other related results in literature.

An effective algorithm to solve option pricing problems
https://ijnaa.semnan.ac.ir/article_4782.html
10.22075/ijnaa.2021.4782

We are aimed to develop a fast and direct algorithm to solve linear complementarity problems (LCP's) arising from option pricing problems. We discretize the free boundary problem of American options in temporal direction and obtain a sequence of linear complementarity problems (LCP's) in the finite dimensional Euclidian space $mathbb{R}^m$. We develop a fast and direct algorithm based on the active set strategy to solve the LCP's. The active set strategy in general needs $O(2^m m^3)$ operations to solve $m$ dimensional LCP's. Using Thomas algorithm, we develop an algorithm with order of complexity $O(m)$ which can extremely speed up the computations.

A generalization of Darbo's theorem with application to the solvability of systems of integraldifferential equations in Sobolev spaces
https://ijnaa.semnan.ac.ir/article_4784.html
10.22075/ijnaa.2021.4784

In this article, we introduce the notion of $(alpha,beta)$generalized MeirKeeler condensing operator in a Banach space, a characterization using strictly Lfunctions and provide an extension of Darbo's fixed point theorem associated with measures of noncompactness. Then, we establish some results on the existence of coupled fixed points for a class of condensing operators in Banach spaces. As an application, we study the problem of existence of entire solutions for a general system of nonlinear integraldifferential equations in a Sobolev space. Further, an example is presented to verify the effectiveness and applicability of our main results.

On the efficient of adaptive methods to solve nonlinear equations
https://ijnaa.semnan.ac.ir/article_4799.html
10.22075/ijnaa.2021.4799
1
The main goal of this work, obtaining a family of Steffensentype iterative methods adaptive with memory for solving nonlinear equations, which uses three selfaccelerating parameters. For this aim, we present a new scheme to construct the selfaccelerating parameters and obtain a family of Steffensentype iterative methods with memory. The selfaccelerating parameters have the properties of simple structure and easy calculation, which do not increase the computational cost of the iterative methods. The convergence order of the new iterative methods has increased from 4 to 8. Also, these methods possess very high computational efficiency. Another advantage of the new method is that they remove the severe condition $f'(x)$ in a neighborhood of the required root imposed on Newton's method. Numerical comparisons have made to show the performance of the proposed methods, as shown in the illustrative examples.

In this paper the implementation of parallel algorithm of alternating direction implicit (ADI) method has been considered. ADI parallel algorithm is used to solve a multiphase multicomponent fluid flow problem in porous media. There are various technologies for implementing parallel algorithms on the CPU and GPU for solving hydrodynamic problems. In this paper GPUbased (graphic processor unit) algorithm was used. To implement the GPUbased parallel ADI method, CUDA and OpenCL were used. ADI is an iterative method used to solve matrix equations. To solve the tridiagonal system of equations in ADI method, the parallel version of cyclic reduction (CR) method was implemented. The cyclic reduction is a method for solving linear equations by repeatedly splitting a problem as a Thomas method. To implement of a sequential algorithm for solving the oil recovery problem, the implicit Thomas method was used. Thomas method or tridiagonal matrix algorithm is used to solve tridiagonal systems of equations. To test parallel algorithms personal computer installed Nvidia RTX 2080 graphic card with 8 GB of video memory was used. The computing results of parallel algorithms using CUDA and OpenCL were compared and analyzed. The main purpose of this research work is a comparative analysis of the parallel algorithm computing results on different technologies, in order to show the advantages and disadvantages each of CUDA and OpenCL for solving oil recovery problems.

Stable numerical solution of an inverse coefficient problem for a time fractional reactiondiffusion equation
https://ijnaa.semnan.ac.ir/article_4810.html
10.22075/ijnaa.2021.4810
1
In this paper, an inverse problem of determining an unknown reaction coefficient in a onedimensional timefractional reactiondiffusion equation is considered. This inverse problem is generally illposed. For this reason, the mollification regularization technique with the generalized crossvalidation criteria will be employed to find an equivalent stable problem. Afterward, a finite difference marching scheme is introduced to solve this regularized problem. The stability and convergence of the numerical solution are investigated. In the end, some numerical examples are presented to verify the ability and effectiveness of the proposed algorithm.

The effect of changes in sealing wall and horizontal drainage of Golfaraj dam on the values of lifting pressure parameters and maximum outlet gradient
https://ijnaa.semnan.ac.ir/article_4815.html
10.22075/ijnaa.2021.4815
1
Dams are always considered as infrastructure structures and have vital value. An earthen dam is a body consisting of discontinuous soil particles of various sizes that need to be placed in front of a stream of water to store it. As water is stored behind the dam and its surface area increases, the potential energy of the water particles increases and due to its porous nature, it begins to move in it. Today, the main problem that has attracted the attention of engineers is the issue of seepage. So that the presence of seepage in earthen dams is inevitable. The aim of the present study was to investigate the different positions of the sealing wall and to select the best angle, length, number and distance, as well as to select the appropriate length for horizontal drainage Due to the geotechnical conditions, it is against the phenomenon of rug and lifting force. GeoStudio software is a collection of soil mechanics software based on finite element method through which various modellings and analyzes can be examined. This software includes various models such as SEEP / W which is used for flow analysis and seepage. In the present study, the SEEP / W model of this software package has been used. The SEEP / W model is based on the Darcy relation, which expresses the passage of water flow through the soil in both saturated and unsaturated states. The results showed that for the sealing wall located above the core, an angle of 20 degrees and for the sealing wall located downstream of the core, an angle of 100 degrees are suitable. Also, the optimal length of the sealing wall is 24 meters and its optimal number is 2. Increasing the distance between the two vertical sealing walls has increased the lifting pressure and reduced the maximum outlet gradient. Increasing the horizontal drainage length reduced the maximum output gradient, while having little effect on the uplift pressure.

Stochastic approach for noise analysis and parameter estimation for RC and RLC electrical circuits
https://ijnaa.semnan.ac.ir/article_4820.html
10.22075/ijnaa.2021.4820
1
The main focus of this paper is to examine the effects of Gaussian white noise and Gaussian colored noise perturbations on the voltage of RC and RLC electrical circuits. For this purpose, the input voltage is assumed to be corrupted by the white noise and the charge is observed at discrete time points. The deterministic models will be transferred to stochastic differential equations and these models will be solved analytically using Ito's lemma. Random colored noise excitations, more close to real environmental excitations, so Gaussian colored noise is considered in these electrical circuits. Scince there is not always a closed form analytical solution for stochastic differential equations, then these models will be solved numerically based on the Euler maruyama scheme. The parameter estimation for these stochastic models is investigated using the least square estimator when the parameters are missing data that it is a concern in electrical engeineering. Finally, some numerical simulations via Matlab programming are carried out in order to show the efficiency and accuracy of the present work.

A modified optimization method for optimal control problems of continuous stirred tank reactor
https://ijnaa.semnan.ac.ir/article_4823.html
10.22075/ijnaa.2021.4823
1
Continuous stirred tank reactor (CSTR) is an important and constructive part in various chemical and process industries and therefore it is necessary to control the process in optimal temperature and concentration conditions. Because of the nonlinear nature and limits of the control input, solving this problem is very difficult. To achieve a suboptimal control policy for chemical processes, we focused on a new construction model. Then, a twophase algorithm, denoted as modified sequential general variable neighborhood search (MSGVNS) algorithm based on three local searches that use efficient neighborhood interchange has been employed to solve CSTR problems numerically. The results of the proposed method show that its convergence to the exact solution is achieved by the accuracy comparable to other numerical algorithms in few times.

The arrow domination in graphs
https://ijnaa.semnan.ac.ir/article_4826.html
10.22075/ijnaa.2021.4826

The arrow domination is introduced in this paper with its inverse as a new type of domination. Let $G$ be a finite graph, undirected, simple and has no isolated vertex, a set $D$ of $V(G)$ is said an arrow dominating set if $N(w)cap (VD)=i$ and $N(w)cap Dgeq j$ for every $w in D$ such that $i$ and $j$ are two nonequal positive integers. The arrow domination number $gamma_{ar}(G)$ is the minimum cardinality over all arrow dominating sets in $G$. Essential properties and bounds of arrow domination and its inverse when $i=1$ and $j=2$ are proved. Then, arrow domination number is discussed for several standard graphs and other graphs that formed by join and corona operations.

An overview of Bayesian prediction of future record statistics using upper record ranked set sampling scheme
https://ijnaa.semnan.ac.ir/article_4828.html
10.22075/ijnaa.2021.4828
1
Two sample prediction is considered for a oneparameter exponential distribution. In practical experiments using sampling methods based on different schemes is crucial. This paper addresses the problem of Bayesian prediction of record values from a future sequence, based on an upper record ranked set sampling scheme. First, under an upper record ranked set sample (RRSS) and different values of hyperparameters, point predictions have been studied with respect to both symmetric and asymmetric loss functions. These predictors are compared in the sense of their mean squared prediction errors. Next, we have derived two prediction intervals for future record values. Prediction intervals are compared in terms of coverage probability and expected length. Finally, a simulation study is performed to compare the performances of the predictors. The real data set is also analyzed for an illustration of the findings.

Existence of solutions of system of functionalintegral equations using measure of noncompactness
https://ijnaa.semnan.ac.ir/article_4847.html
10.22075/ijnaa.2021.4847
1
We propose to investigate the solutions of system of functionalintegral equations in the setting of measure of noncompactness on realvalued bounded and continuous Banach space. To achieve this, we first establish some new Darbo type fixed and coupled fixed point results for $mu$set $(omega,vartheta)$contraction operator using arbitrary measure of noncompactness in Banach spaces. An example is given in support for the solutions of a pair of system of functionalintegral equations.

On generalized $Phi$strongly monotone mappings and algorithms for the solution of equations of Hammerstein type
https://ijnaa.semnan.ac.ir/article_4866.html
10.22075/ijnaa.2021.4866
1
In this paper, we consider the class of generalized $Phi$strongly monotone mappings and the methods of approximating a solution of equations of Hammerstein type. Auxiliary mapping is defined for nonlinear integral equations of Hammerstein type. The auxiliary mapping is the composition of bounded generalized $Phi$strongly monotone mappings which satisfy the range condition. Suitable conditions are imposed to obtain the boundedness and to show that the auxiliary mapping is a generalized $Phi$strongly which satisfies the range condition. A sequence is constructed and it is shown that it converges strongly to a solution of equations of Hammerstein type. The results in this paper improve and extend some recent corresponding results on the approximation of a solution of equations of Hammerstein type.

Investigating the dynamics of Lotka$$Volterra model with disease in the prey and predator species
https://ijnaa.semnan.ac.ir/article_4867.html
10.22075/ijnaa.2021.4867
1
In this paper, a predator$$prey model with logistic growth rate in the prey population was proposed. It included an SIS infection in the prey and predator population. The stability of the positive equilibrium point, the existence of Hopf and transcortical bifurcation with parameter $a$ were investigated, where $a$ was regarded as predation rate. It was found that when the parameter $a$ passed through a critical value, stability changed and Hopf bifurcation occurred. Biologically, the population is positive and bounded. In the present article, it was also shown that the model was bounded and that it had the positive solution. Moreover, the current researchers came to the conclusion that although the disease was present in the system, none of the species would be extinct. In other words, the system was persistent. Important thresholds, $R_{0}, R_{1}$ and $R_{2}$, were identified in the study. This theoretical study indicated that under certain conditions of $R_{0}, R_{1}$ and $R_{2}$, the disease remained in the system or disappeared.

The semiobnoxious minisum circle location problem with Euclidean norm
https://ijnaa.semnan.ac.ir/article_4869.html
10.22075/ijnaa.2021.4869
1
The objective of the classical version of the minisum circle location problem is finding a circle $C$ in the plane such that the sum of the weighted distances from the circumference of $C$ to a set of given points is minimized, where every point has a positive weight. In this paper, we investigate the semiobnoxious case, where every existing facility has either a positive or negative weight. The distances are measured by the Euclidean norm. Therefore, the problem has a nonlinear objective function and global nonlinear optimization methods are required to solve this problem. Some properties of the semiobnoxious minisum circle location problem with Euclidean norm are discussed. Then a cuckoo optimization algorithm is presented for finding the solution of this problem.

Cystoscopic image classification by an ensemble of VGGnets
https://ijnaa.semnan.ac.ir/article_4876.html
10.22075/ijnaa.2021.4876
1
Over the last three decades, artificial intelligence has attracted lots of attentions in medical diagnosis tasks. However, few studies have been presented to assist urologists to diagnose bladder cancer in spite of its high prevalence worldwide. In this paper, a new computer aided diagnosis system is proposed to classify four types of cystoscopic images including malignant masses, benign masses, blood in urine, and normal. The proposed classifier is an ensemble of a wellknown type of convolutional neural networks (CNNs) called VGGNet. To combine the VGGNets, bootstrap aggregating approach is used. The proposed ensemble classifier was evaluated on a dataset of 720 images. Based on the experiments, the presented method achieved an accuracy of 63% which outperforms base VGGNets and other competing methods.

Outlier detection in test samples and supervised training set selection
https://ijnaa.semnan.ac.ir/article_4878.html
10.22075/ijnaa.2021.4878
1
Outlier detection is a technique for recognizing samples out of the main population within a data set. Outliers have negative impacts on classification. The recognized outliers are deleted to improve the classification power generally. This paper proposes a method for outlier detection in test samples besides a supervised training set selection. Training set selection is done based on the intersection of three well known similarity measures namely, jacquard, cosine, and dice. Each test sample is evaluated against the selected training set for possible outlier detection. The selected training set is used for a twostage classification. The accuracy of classifiers are increased after outlier deletion. The majority voting function is used for further improvement of classifiers.

he aim of this research is to initiate a new concept of domination in fuzzy graphs which is called a fuzzy coeven domination number denoted by $gamma_{f c o}(G) .$ We will touch only a few aspects of the theory to of this definition. Some properties and boundaries of this definition are introduced. The fuzzy coeven domination number of fuzzy certain graphs as fuzzy complete, fuzzy complete bipartite, fuzzy star, fuzzy cycle, fuzzy null, fuzzy path, and fuzzy star are determined. Additionally, this number is computed for the complement of mentioned above fuzzy certain graphs. Finally, this number is also determined for the join to mentioned above fuzzy certain graphs with itself.

A simple, efficient and accurate new Liegroup shooting method for solving nonlinear boundary value problems
https://ijnaa.semnan.ac.ir/article_4935.html
10.22075/ijnaa.2019.1543.1403
1
The present paper provides a new method for numerical solution of nonlinear boundary value problems. This method is a combination of group preserving scheme (GPS) and a shootinglike technique which takes advantage of two powerful methods for solving nonlinear boundary value problems. This method is very effective to search unknown initial conditions. To demonstrate the computational efficiency, the mentioned method is implemented for some nonlinear exactly solvable differential equations including strongly nonlinear Bratu equation, nonlinear reactiondiffusion equation and one singular nonlinear boundary value problem. It is also applied successfully on two nonlinear threepoint boundary value problems and a thirdorder nonlinear boundary value problem which the exact solutions of this problems are unknown. The examples show the power of method to search for unique solution or multiple solutions of nonlinear boundary value problems with high computational speed and high accuracy. In the test problem 5 a new branch of solutions is found which shows the power of the method to search for multiple solutions and indicates that the method is successful in cases where purely analytic methods are not.

Characterizations of the set containment with starshaped constraints
https://ijnaa.semnan.ac.ir/article_3533.html
10.22075/ijnaa.2018.13932.1727

In this paper, we first give a separation theorem for a closed starshaped set at the origin and a point outside it in terms of separation by an upper semicontinuous and superlinear function, and also, we introduce a $nu$starshapedconjugation. By using this facts, we present characterizations of the set containment with infinite starshaped constraints defined by weak inequalities. Next, we give characterizations of the set containment with infinite evenly radiant constraints defined by strict or weak inequalities. Finally, we give a characterization of the set containment with an upper semicontinuous and radiant constraint, in a reverse starshaped set, defined by a costarshaped constraint. These results have many applications in Mathematical Economics, in particular, in Utility Theory.

New formula to calculate the number of designs in RADG cryptosystem
https://ijnaa.semnan.ac.ir/article_4937.html
10.22075/ijnaa.2021.4937

Reaction automata direct graph (RADG) is a new technique that uses the automata direct graph method to represent a certain design for encryption and decryption. Jump states are available in the RADG design that enables the encipher to generate different ciphertexts each time from the same plaintext and wherein not a single ciphertext is related to a certain plaintext. This study created a matrix representation for RADG designs that allows the calculation of the number of cases ($F_{Q}$)mathematically possible for any design of the set $Q$. $F_{Q}$ is an important part of the function $mathrm{F}(mathrm{n}, mathrm{m}, lambda)$ that calculates the total number of cases of a certain design for the values $Q, R, sum, psi, J$ and $T$. This paper produces a mathematical equation to calculate $F_{Q}$.

This paper introduces a new proposed algorithm of numerical integration evaluation regarded as optimization problem solution. The new method is characterized to have superiority features such as attractive, accurate and rapid. An improvement of polynomial regression has been done by selecting nearest neighbors points being searched around of the values of regression coefficients which calculated by using least squares method. Furthermore, Trapezoidal and Simpson methods were considered as traditional methods in numerical integration. In this regard, comparison has been done among all four methods used in simulation application via MATLAB program that have been performed to achieve the desired numerical results for the four methods. As conclusion, the proposed algorithm approved its superiority.

We present a model of the fluid flow between elastic walls simulating arteries actively interacting with the blood. The lubrication theory for the flow is coupled with the pressure and shear stress from the walls. The resulting nonlinear partial differential equation describes the displacement of the walls as a function of the distance along the flow and time.

New subclass of analytic functions defined by subordination
https://ijnaa.semnan.ac.ir/article_4940.html
10.22075/ijnaa.2018.13582.1706
1
By using the subordination relation $"prec"$, we introduce an interesting subclass of analytic functions as follows: begin{equation*} mathcal{S}^*_{alpha}:=left{fin mathcal{A}:frac{zf'(z)}{f(z)}prec frac{1}{(1z)^alpha}, z<1right}, end{equation*} where $0<alphaleq1$ and $mathcal{A}$ denotes the class of analytic and normalized functions in the unit disk $z<1$. In the present paper, by the class $mathcal{S}^*_{alpha}$ and by the Nunokawa lemma we generalize a famous result connected to starlike functions of order $1/2$. Also, coefficients inequality and logarithmic coefficients inequality for functions of the class $mathcal{S}^*_{alpha}$ are obtained.

The aim of this paper is to construct a complete metric space of fuzzy valued image functions and to define a fractal transform operator T. Contraction of T is guarantees the existence of its fixed point. A fuzzy point is considered for this purpose as a crisp point and approached through classical method on proving the completeness of the space.

Classification of problems of determining the maximum common fragments for two structures of a temporal digraph
https://ijnaa.semnan.ac.ir/article_4942.html
10.22075/ijnaa.2021.4942

A new approach is proposed for classifying the problems of determining the maximum common fragments $(M C F)$ for two connected structures included in the $T$digraph, based on the type of the maximum common fragment. A tree of classification the problems of determining the maximum common fragments $(M C F)$ for two structures $t_{i} G, t_{j} Gleft(M C Fleft(t_{i} G, t_{j} Gright)right)$ included in the $T$digraph is proposed. Examples are given for a digraph $t G$ with three types of its fragments (parts), and for five connectivity types of digraphs. The formulation of six basic problems of determining the maximum common fragments $ (MCF) $ for two connected structures included in the $T$digraph is given. A classification is proposed for an isomorphic embedding of a digraph into another.

Infinitesimal generators of Lie symmetry group of parametric ordinary differential equations
https://ijnaa.semnan.ac.ir/article_4943.html

Lie’s theory of symmetry groups plays an important role in analyzing and solving differential equations; for instance, by decreasing the order of equation. Moreover, there are some analytic methods to find the infinitesimal generators that span the Lie algebra of symmetries. In this paper, we first converted the problem of finding infinitesimal generators in to the problem of solving a system of polynomial equations in the context of computational algebraic geometry. Then, we used Gröbner basis a novel computational tool to solve this problem. As far as we know, when a differential equation contains some parameters, there is no linear algebraic algorithm up to our knowledge to deal with these parameters; so, we must apply the algorithms, which are based on Gröbner basis.

New estimates of GaussJacobi and trapezium type inequalities for strongly $(h_{1},h_{2})$preinvex mappings via general fractional integrals
https://ijnaa.semnan.ac.ir/article_4951.html
10.22075/ijnaa.2020.19718.2096
1
In this paper, authors discover two interesting identities regarding GaussJacobi and trapezium type integral inequalities. By using the first lemma as an auxiliary result, some new bounds with respect to GaussJacobi type integral inequalities for a new class of functions called strongly $(h_{1},h_{2})$preinvex of order $sigma>0$ with modulus $mu>0$ via general fractional integrals are established. Also, using the second lemma, some new estimates with respect to trapezium type integral inequalities for strongly $(h_{1},h_{2})$preinvex functions of order $sigma>0$ with modulus $mu>0$ via general fractional integrals are obtained. It is pointed out that some new special cases can be deduced from main results. Some applications to special means for different real numbers and new approximation error estimates for the trapezoidal are provided as well. These results give us the generalizations of some previous known results. The ideas and techniques of this paper may stimulate further research in the fascinating field of inequalities.

Different estimation procedures for the probability density and cumulative distribution functions of the generalized inverted Weibull distribution are discussed. For this purpose, the parametric and nonparametric estimation approaches as maximum likelihood, uniformly minimum variance unbiased, percentile, least squares and weighted least squares estimators are considered and compared. The expectations and mean square error of the maximum likelihood and uniformly minimum variance unbiased estimation are provided in the closedform whereas, for nonparametric estimation methods (percentile, least squares and weighted least squares), the expectations and mean square error are computed via the simulation data. The Monte Carlo simulations are provided to assess the performances of the proposed estimation methods. Finally, the analysis of the real data set has been presented for illustrative purposes.

A new Robust algorithm for penalized regression splines based on modeestimation
https://ijnaa.semnan.ac.ir/article_4971.html
10.22075/ijnaa.2021.23023.2458
1
The main purpose of present article is proposed an effective method for robust fitting penalized regression splines models. According to such a context a comparative analysis with two common robust techniques, Mtype estimator, Stype estimator, and nonrobust least squares (LS) for penalized regression splines (PRS) has been implemented. Because the penalized regression splines are recently a common approach to smoothing noisy data for its simplicity, efficiency, and significantly reducing disturbance of outliers and its flexibility in monitoring nonlinear data trends. In many cases, it is difficult to determine the most suitable form and a way of designing a data is needed when faced with many smoothing problems. The executing aspects of fitting precision and robustness of the four estimators have a thorough evaluation of their performance on R codes. A comparative analysis demonstrates that the proposed method can resist the noise effect in both simulated and real data examples compared to other robust estimators with different combinations of contamination. These findings are used as guidance for finding a specific method to pulsing smoothing noisy data

Analysis and control of a 4D hyperchaotic system with passive control
https://ijnaa.semnan.ac.ir/article_4974.html
10.22075/ijnaa.2020.21594.2278

In this study, the dynamical behavior of the fourdimensional (4D) hyperchaotic system is analyzed. Its chaotic dynamical behaviors and basic dynamical properties are presented by Lyapunov exponents, stability analysis, and KaplanYorke dimension. Then, the control of 4D hyperchaotic system is implemented by using passive control. The global asymptotic stability of the system is guaranteed by using Lyapunov function. Simulation results are shown to validate all theoretical analysis and demonstrate the effectiveness of the proposed control method. By applying the passive controllers, the system under chaotic behavior converges to the equilibrium point at origin asymptotically.

We generalize the notion of the antiDaugavet property (aDP) to the antiNorder polynomial Daugavet property (aNPDP) for Banach spaces by identifying a good spectrum of a polynomial and prove that locally uniformly alternatively convex or smooth Banach spaces have the amDP for rank1 polynomials. We then prove that locally uniformly convex Banach spaces have the aNPDP for compact polynomials if and only if their norms are eigenvalues, and uniformly convex Banach spaces have the aNPDP for continuous polynomials if and only if their norms belong to the approximate spectra.

Integrated three layer supply chain inventory model for price sensitive and time dependent demand with suggested retail price by manufacturer
https://ijnaa.semnan.ac.ir/article_4979.html
10.22075/ijnaa.2018.14334.1749

This paper presents an integrated three layer supply chain policy for multichannel and multiechelon consisting manufacturer, distributors and retailers as supply chain members. The demand of retailers end is considered as linear function of time and retail price. The average net profit function per unit time is derived for each supply chain member which are based on demand of retailer's end. Since holding cost of goods/inventory is expensive in developed areas, we have introduced a new concept to share holding cost among distributors and retailers. We have optimized lot size, retailing price and replenishment time interval for retailers. We have also optimized initial inventory level and wholesale price for distributors and manufacturer respectively. This study is performed in two different categories one is decentralized and other is centralized scenario. The profit function of each supply chain members has been derived and shown as a concave function with respect to decision variables. More over propositions and results are made to illustrate the proposed model and we have sensitive analyzed it with numerical example.

We show in this paper that a mapping $f$ satisfiesthe following functional equationbegin{eqnarray*}biguplus_{x_2,cdots,x_{d+1}}^{d}f(x_1) = 2^{d} sum_{i=1}^{d+1}f(x_i),end{eqnarray*}if and only if it is quadratic. In addition, we investigate generalized HyersUlam stability problem for the equation, and thus obtain an asymptotic property of quadratic mappings as applications.

We consider the initial value problem for a class of nonlinear fractional neutral functional differential equations with infinite delay involving the standard fractional derivative in the sense of Caputo. By using a variety of tools of fractional calculus including the Banach contraction principle and the Schaefer fixed point theorem, the existence, uniqueness and continuous dependence results are obtained in the space of continuous functions.

Accelerated failure time model sometimes symbolized as AFT model, is an important regression model in survival analysis. In this article, we applied AFT model to the data of lung cancer patient in order to identify the must important factors affecting the patient's survival time. The results showed a well performance for this model, as based on some statistical criteria, the factors that are consistent with the opinion of specialists in in uencing survival time were identified, as the factors (smoking, treatment, proliferation, location of residence) of the main factors aecting the life of a person with this disease.

This study aims to design a multiperiod credit portfolio optimization model with a nonlinear multiobjective fuzzy mathematical modeling approach. In terms of data collection, this study is a descriptivesurvey research and in terms of the nature and purpose of the research, it is an applied one. The statistical population of the research includes all facility files of the last 10 years as well as the statements of financial position of Ansar Bank branches affiliated with Sepah Bank, selected by census method. The risk criteria used in the models include Average Value at Risk (AVaR), Conditional Value at Risk (CVAR) and SemiEntropy. First, having reviewed the research literature, the objectives and indices of the portfolio optimization issue were investigated based on the practical character of this issue and the main indices were selected. Then, each of the objectives and constraints were specified in a state of uncertainty and ambiguity, based on the principles of fuzzy credibility theory, for a state in which the expected rate of stock return is a triangular fuzzy number. Finally, three multiobjective fuzzy models were designed based on the selected criteria. Research models were implemented using MOPSO algorithm. The software used in conducting the research was MATLAB software. The results indicated that the CVAR model performed better than the other two models, i.e. AVAR and SemiEntropy, in evaluating optimal portfolios.
