The<br />hybrid models are composed of the shearlet filter and the adaptive Wiener filter in different forms.<br />The optimization of various models is accomplished by the genetic algorithm. Next, regarding the<br />significant relationship between Optimal models and input images, changing the structure of Optimal<br />models for image denoising is modelled by the ANFIS. The eight hundred digital images are used<br />as train images. For eight hundred training images, Sixty seven models are found. For integrated<br />evaluation, the amounts of image attributes such as Peak Signal to Noise Ratio, Signal to Noise Ratio,<br />Structural Similarity Index, Mean Absolute Error and Image Quality Assessment are evaluated by<br />the Fuzzy deduction system. Finally, for the features of a sample noisy image as test data, the<br />proposed denoising model of ANFIS is compared with wavelet filter in 2 and 4 level , Fast bilateral<br />filter, TV-L1, Median, shearlet filter and the adaptive Wiener filter. In addition, run time of proposed<br />method are evaluated. Experiments show that the proposed method has better performance than<br />others.https://ijnaa.semnan.ac.ir/article_4651_7f3f4a9bf38ac5c9f2273a207a4f41db.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682212120210201A numerical solution of variable order diusion and wave equations2736465210.22075/ijnaa.2021.4652ENNematollahKadkhodaDepartment of Mathematics, Faculty of Basic Sciences, Bozorgmehr University of Qaenat, Qaenat, Iran.HosseinJafariDepartment of Mathematics, University of Mazandaran, Babolsar, Iran.

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 meta-heuristic 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.https://ijnaa.semnan.ac.ir/article_4657_3814331aca46a0fed014e98d5b27c04f.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682212120210201Linkage factors optimization of Multi-outputs of compliant mechanism using Response Surface5974465810.22075/ijnaa.2021.4658ENRamiAlfattaniDepartment of Mechanical Engineering, College of Engineering and Islamic Architecture, Umm Al-Qura University,

Makkah, Kingdom of Saudi Arabia.Journal Article20201028This paper presents a linkage factors synthesis and multi-level optimization technique for bi-stable compliant mechanism. The linkage synthesis problem is modeled as multiple level factors and responses optimization problem with constraints. The bi-stable compliant mechanism is modeled as a crank slider mechanism using pseudo-rigid-body model (PRBM). The model exerts the large deflection of flexible element which explains compliant mechanism’s bi-stable 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 (Theta-cap 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 Box-Behnken design of RSM is applied with a desirability function approach to determine the optimum set of parameters for minimizing Fmax and maximizing the Theta-cap (Θ1). Thus, this technique shown flexibility based on the product application could be tested and established.https://ijnaa.semnan.ac.ir/article_4658_362234389ac000b2d052af105a7e4781.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682212120210201Excellence of Financial Reporting Information and Investment Productivity7586465910.22075/ijnaa.2021.4659ENYidanZhuSchool of Housing, Building and Planning, Universiti Sains Malaysia (USM), Malaysia.ErnawatiMustafa KamalSchool of Housing, Building and Planning, Universiti Sains Malaysia (USM), Malaysia.GuoshengGaoSchool of Physics, Universiti Sains Malaysia (USM), MalaysiaAlim AlAyub AhmedSchool of Accounting, Jiujiang University, Jiujiang, Jiangxi, China.A B MAsadullahKulliyyah of Economics and Management Sciences, International Islamic University Malaysia (IIUM),Malaysia.Praveen KumarDonepudiEnterprise Architect, Information Technology, UST-Global, Inc.,Ohio, USA.Journal Article20201028Objective –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 firm-years and are made up of 257 subsamples of underinvestment and 411 sub-samples 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 sub-samples) has a positive association with investment performance. Although the evidence is not consistent across sub-samples, 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.https://ijnaa.semnan.ac.ir/article_4659_9ccd71f1f578ef006929956697b6d16a.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682212120210201Automatic QoS-aware Web Services Composition based on Set-Cover Problem87109466410.22075/ijnaa.2021.4664ENMortezaKhani DehnoiDepartment of Computer Engineering, Faculty of Engineering, Ferdowsi University of Mashhad, Mashhad, Iran.SaeedArabanDepartment of Computer Engineering, Faculty of Engineering, Ferdowsi University of Mashhad, Mashhad, IranJournal Article20201104By definition, web-services composition works on developing merely optimum coordination among a number of available web-services to provide a new composed web-service intended to satisfy some users requirements for which a single web service is not (good) enough. In this article, the formulation of the automatic web-services composition is proposed as several set-cover problems and an approximation algorithm has been exploited to solve them. In proposed method, the web-service composition has been carried out within two main phases, the top-down expansion of the composition tree, and the production of composed service by bottom-up 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 post-conditions of the requested service towards its input or pre-conditions. 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 non-leaf node of the tree, a set-cover problem is produced and solved using a greedy approximation algorithm. If the production and solving of the set-cover 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 near-optimal and QoS-aware composed services.https://ijnaa.semnan.ac.ir/article_4664_9768c09f62e15bf392531522635c1cf0.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682212120210201A method for analyzing the problem of determining the maximum common fragments of temporal directed tree, that do not change with time111118467110.22075/ijnaa.2021.4671ENAli RashidIbrahimDepartment of Applied Mathematics, College of Science University of Anbar Ramadi, IraqJournal Article20201108In this study two actual types of problems are considered and solved: 1) determining the maximum common connected fragment of the T-tree (T-directed tree) which does not change with time; 2) determining all maximum common connected fragments of the T-tree (T-directed tree) which do not change with time.

Box: 11155-4563, Tehran, Iran0000-0002-6757-926XJournal Article20181103A Location-Arc Routing Problem (LARP) is a practical problem, while a few mathematical programming models have been considered for this problem. In this paper, a mixed non-linear programming model is presented for a multi-period 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 node-based with close nods and can be transformed into arc-based. 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.https://ijnaa.semnan.ac.ir/article_4752_80655ce3cb462e923fb5c55f2c35578f.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682212120210201A Credible Threat against Oil Sanctions for Iran175178461410.22075/ijnaa.2020.19232.2068ENAbbasJavadianFaculty of Physics, Semnan University,

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.

Using Thomas algorithm, we develop an algorithm with order of complexity $O(m)$ which can extremely speed up the computations.https://ijnaa.semnan.ac.ir/article_4782_29d13b4a8016fe2587deba487d223462.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682212120210201On certain properties for new subclass of meromorphic starlike functions273285478310.22075/ijnaa.2021.4783ENSirousMoradiDepartment of Mathematics, Faculty of science, Lorestan University, 68151-4-4316, Khorramabad, IranMohammadTaatiDepartment of Mathematics, Faculty of science, Payame Noor University, P.O.Box 19395-3697, Tehran, IranJournal Article20200616In this paper we studying some properties of starlike function of order $lambda$ which satisfy in the condition<br /> $$Re(frac{zf^{'}(z)}{f(z)}+alphafrac{z^{2}f^{''}(z)}{f(z)})<1-lambda+alpha$$<br /> \for all $zin U={z:|z|<1}$, where $f(z)=1+sum_{k=1}^infty a_{k}z^{k}$ is analytic in $U$, $0leqslantalpha<2$ and $0leqslantlambda<1$.

For this aim, we present a new scheme to construct the self-accelerating parameters and obtain a family of Steffensen-type iterative methods with memory. The self-accelerating 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.https://ijnaa.semnan.ac.ir/article_4799_2486d12e3e7c80f0885a4c92cac99308.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682212120210201Positive Solutions for Fractional-order Nonlinear Boundary Value Problems on Infinite Interval317335480010.22075/ijnaa.2021.4800ENIlkayYaslan KaracaDepartment of Mathematics, Faculty of Science, Ege University, 35100 Bornova, Izmir, TurkeyDonduOzDepartment of Mathematics, Faculty of Science, Ege University, 35100 Bornova, Izmir, TurkeyJournal Article20180626In this paper, Avery-Henderson (Double) fixed point theorem and Ren fixed point theorem are used to investigate the existence of positive solutions for fractional-order nonlinear boundary value problems on infinite interval.

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.<br /> 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 <br /><br /> 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.<br /> 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.https://ijnaa.semnan.ac.ir/article_4815_a02900205779e71570df4a951fc5a3e4.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682212120210201Stochastic approach for noise analysis and parameter estimation for RC and RLC electrical circuits433444482010.22075/ijnaa.2021.4820ENParisaNabatiFaculty of Science, Urmia University of Technology, Urmia, IranRahmanFarnooshFaculty of Mathematics, Iran University of Science and Technology, Tehran, IranJournal Article20210131The 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.https://ijnaa.semnan.ac.ir/article_4820_471c1a66b3a88830befae95949607263.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682212120210201A modified optimization method for optimal control problems of continuous stirred tank reactor445459482310.22075/ijnaa.2021.4823ENMitraSalimiDepartment of Mathematics, Payame Noor University, Tehran, P.O.

Because of the nonlinear nature and limits of the control input, solving this problem is very difficult. To achieve a sub-optimal control policy for chemical processes, we focused on a new construction model. Then, a two-phase 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.https://ijnaa.semnan.ac.ir/article_4823_7d627c9fd5e0da83d23591968bf53ad7.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682212120210201E-Bayesian Estimation of Parameters of Inverse Weibull Distribution based on a Unified Hybrid Censoring Scheme461472482510.22075/ijnaa.2021.4825ENShahramYaghoubzadeh ShahrestaniDepartment of Statistics, Payame Noor University, P.

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.

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 functional-integral equations.https://ijnaa.semnan.ac.ir/article_4847_3ef2e986f8037f28dfd9791dcb68dbd1.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682212120210201Ciric Type multi-valued $alpha _{ast }$-$eta _{ast }$-$theta $-Contractions on b-meric spaces with Applications597614486510.22075/ijnaa.2021.4865ENEskandarAmeerDepartment of Mathematics, Taiz University, Taiz, YemenHassenAydiUniversity of Dammam, Department of Mathematics.

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.https://ijnaa.semnan.ac.ir/article_4866_ad5d2a21a89586ae81e2b41701e58659.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682212120210201Investigating the dynamics of Lotka$-$Volterra model with disease in the prey and predator species633648486710.22075/ijnaa.2021.4867ENAtenaGhasemabadiEsfarayen University of Technology, Esfarayen, North Khorasan, IranMohammad HossienRahmani DoustDepartment of Mathematics, University of Neyshabur, Adib BLVD, Neyshabur, IranJournal Article20210215In 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 transcritical 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 occured. 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 althought 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. https://ijnaa.semnan.ac.ir/article_4867_07d51ef29b1b531eb1a1bbb60e086c0d.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682212120210201Construction of Generating Functions of the Products of Vieta Polynomials with Gaussian Numbers and Polynomials649668486810.22075/ijnaa.2021.4868ENSouhilaBoughabaLMAM Laboratory and Department of Mathematics, Mohamed Seddik Ben Yahia University, Jijel, AlgeriaNabihaSabaLMAM Laboratory and Department of Mathematics, Mohamed Seddik Ben Yahia University, Jijel, AlgeriaAliBoussayoudLMAM Laboratory and Department of Mathematics, Mohamed Seddik Ben Yahia University, Jijel, Algeria.Journal Article20210215In the present paper, we introduce the recurrence relations of Vieta Fibonacci, Vieta Lucas, Vieta Pell and Vieta Pell Lucas polynomials.

In this paper, we investigate the semi-obnoxious 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 semi-obnoxious minisum circle location problem with Euclidean norm are discussed. Then a cuckoo optimization algorithm is presented for finding the solution of this problem.https://ijnaa.semnan.ac.ir/article_4869_42ebf726b5dc93e5d0a99ef7b8525b66.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682212120210201An Existence Result of Three Solutions for a $mathbf{2n}$-th-Order Boundary-Value Problem679691487010.22075/ijnaa.2021.4870ENOsmanHalakooDepartment of Mathematics, Science and Research Branch, Islamic Azad University, Tehran, IranMahdiAzhiniDepartment of Mathematics, Faculty of Mathematical Sciences, University of Mazandaran, Babolsar, IranGhasemAfrouziDepartment of Mathematics, Science and Research Branch, Islamic Azad University, Tehran, IranJournal Article20210216In this paper, we establish the existence of at least three weak solutions for some one-dimensional $2n$-th-order equations in a bounded domain.

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 well-known type of convolutional neural networks (CNNs) called VGG-Net. To combine the VGG-Nets, 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 VGG-Nets and other competing methods.https://ijnaa.semnan.ac.ir/article_4876_84b5959108e6a83053f86305d7229b63.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682212120210201Outlier Detection in Test Samples and Supervised Training Set Selection701712487810.22075/ijnaa.2021.4878ENNavidMohseniDepartment of Computer Engineering, Babol Branch, Islamic Azad University, Babol, IranHosseinNematzadehDepartment of Computer Engineering, Sari Branch, Islamic Azad University, Sari, IranEbrahimAkbariDepartment of Computer Engineering, Sari Branch, Islamic Azad University, Sari, IranJournal Article20210226Outlier 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 two-stage classification. The accuracy of classifiers are increased after outlier deletion. The majority voting function is used for further improvement of classifiers.https://ijnaa.semnan.ac.ir/article_4878_5894efa0a77479f846519520fb0752e2.pdf
