https://ijnaa.semnan.ac.ir/article_4373_483.html
In this article, a new approach for the efficient design of quantum-dot cellular automata (QCA) circuits is introduced. The main advantages of the proposed idea are the reduced number of QCA cells as well as increased speed, reduced power dissipation and improved cell area. In many cases, one needs to double the effect of a particular inter median signal. State-of-the-art designs utilize a kind of fan out to achieve these resulting in increased number of cells, dissipating more power and decreasing the overall speed of the circuits. In this paper, we have presented cell alignment to multiply the effect of a certain signal by two, three or even more. This can be considered as a new vision to design any arbitrary circuit needing this property. Furthermore, a new coplanar crossover approach has been introduced which is able to make the coplanar crossover in two consecutive clocks with one rotated cell in the worst case. In order to prove the efficiency of the proposed ideas, a new Full Adder cell and a new Carry Ripple Adder (4-bit) have been designed which provides less QCA cell count as well as less power dissipation and cost.Thu, 30 Apr 2020 19:30:00 +0100A common fixed point theorem via measure of noncompactness

https://ijnaa.semnan.ac.ir/article_4375_483.html
Careful decision-making to select contractors to manage a project is one of the most important factors in the success and efficiency of a project. It is such that extracting a decision function from the set of factors influencing the selection of contractors can play an important role in improving project performance; therefore, providing a decision function is the main goal of this research. In this paper, the decision model is estimated in the form of linear and exponential equations using the Particle Swarm Optimization Algorithm (PSO) technique. The superior function is selected through the selection of the best estimation model based on the selection criteria of the competing function. Then, it is attempted to predict the values of the decision function. In this paper, for the optimal decision making function, a function of contractors' technical capability, contractors' behavioral capability, company capacity and facilities and project outsourcing goals are considered. The research results show that the linear function explains the efficient selection of a contractor with higher accuracy. The optimal decision-making function shows that MAPNA managers place more emphasis on MAPNA's resources, facilities, and capabilities to efficiently select a contractor. It can also be predicted that in future selections, managers will focus on the ability of MAPNA to cooperate with the contractor, and based on this, MAPNA group subsidiaries will be given priority in the selection.Thu, 30 Apr 2020 19:30:00 +0100Measuring the Efficiency of Banks' Performance Based on Economic Policies Using Data ...
https://ijnaa.semnan.ac.ir/article_4380_483.html
Due to long-term and all-compassing sanctions and the instability of political engagements with the other countries, Iran's economy more than ever should adjust its governance system to minimize economic Problems. As the most important financial institution, banks play an important role in the national economy. Considering the present and future economic conditions, the banks management always tries to improve banking services, marketing, innovation in service delivery, competition with other banks, considering the current and future economic conditions. Therefore, one of the goals of banks is to increase economic efficiency. Data envelopment analysis is a mathematical model to evaluate the relative efficiency of decision-making units. In this study, the efficiency of 83 first-class branches of Mellat Bank was analyzed using data envelopment analysis during 2016 and 2017 with an input-based approach and assuming a variable return to scale. In order to achieve efficiency, three inputs of effective deposits, loan, delayed debts, and an input of profit and loss were used. Finally, the efficiency of the branches was calculated using the Malmquist index. The research data were collected through the bank's annual report and analyzed using Lingo and Eviwes software. The present study is aimed to obtain the effectiveness of the bank's management using a three-stage data envelopment analysis. According to the results obtained after adjusting the environmental factors and statistical disturbance and comparing with the efficiency obtained before adjusting the inputs, it was found that environmental variables have a significant effect on the effectiveness of bank branches. According to the results of this research, it can be concluded that in many cases, the ineffectiveness of managers can be related to environmental and uncontrollable factors of managers, rather than to the manager's qualification.Thu, 30 Apr 2020 19:30:00 +0100To Do or Not to Do: Game Theory and Literature
https://ijnaa.semnan.ac.ir/article_4382_483.html
Game theory, a method of applied mathematics, has been used to study a wide range of topics. Literature is also a fertile ground for the application of Game theory. If one models literary texts as a series of decisions in which each character's decision or choice is dependent on the previous ones of others, it looks like a game, according to the formal game-theory definition. Thus irrational decisions or actions are rational in the context of a game. The current study aims to revisit Shakespeare's tragedies, Hamlet, Othello, and Antony and Cleopatra, in light of the game theory and model them in trees and matrices. These tragedies are nonzero-sum Games and there are no winners at the end. Moreover the characters' dominant strategies are associated with Nash Equilibrium.Thu, 30 Apr 2020 19:30:00 +0100The Spatial Modeling and Analysis of Ancient Sites of Khonj County Using Hybrid AND-GIS Analysis
https://ijnaa.semnan.ac.ir/article_4383_483.html
In the new thinking of the scientific and academic community of Iran, applying science and guiding it to meet the fundamental needs of human society is one of the most important tasks. The identification of these phenomena with the help of GIS theoretical spatial sciences leads to the identification of how each of the human phenomena has been established in the past. Spatial modeling for spatial analysis and scattering of archeological sites in Khonj County is the main purpose of the present research. In terms of purpose and terms of methodology, this research is applied and descriptive-analytical, based on the library, model, and spatial studies. The selected indicators were collected in two stages by studying the records (research projects, statistics, books), using the viewpoints of the experts (taking advantage of Delphi's method and extracting the opinions of academic theorists and managers of related organizations), and they were integrated using the Delphi method. In this section, 14 indicators were identified, and then the ANP-Dematle hybrid analytical model was used to identify the effect of indicators and criteria on each other and ranking. Finally, they were overlapped by GIS software using fuzzy analysis. Research results show: the latitude variable (a3) has the highest impressment (0.120) and then variables of the gradient (c3) and height (b1) with impressment of 0.118 and 0.117 are in the next ranks, respectively. The results of the analysis of fourteener indicators in the ArcGis software environment, which are effective in determining the spatial scattering of 93 archaeological sites show that distance and proximity to water, good soil, and high altitude are some of the reasons for the formation of settlements in this county. The most important reasons that influence the settlement patterns of this region are dependence on three important characteristics: water, good soil for agriculture as well as suitable height.Thu, 30 Apr 2020 19:30:00 +0100An Intelligent Model to Predict the Development Time and Budget of Software Projects
https://ijnaa.semnan.ac.ir/article_4384_483.html
Today, software projects are a major part of information and business technology. Estimating the cost and delivery time of a project is one of the most important aspects of its development process. The results of this estimate are directly related to the failure or success of the whole project. Project anomalies, high diversity, intangibility, and poor standards are obstacles that have hampered various current forecasting models. In this regard, the aim of this paper is to provide an intelligent hybrid model that is able to weigh the project features properly. The main idea of the proposed model is based on mathematical methods, soft computing and using previous estimation methods. After the complete introduction of the new model, its efficiency is evaluated using Desharnais and ISBSG databases. The results indicate higher accuracy and greater flexibility of the proposed model. Improvement rate shows in the various metrics such as MdMRE, Pred(0.25) and MMRE separately, but the average improvement rate is 31%.Thu, 30 Apr 2020 19:30:00 +0100Analysis of the Causal Relationships Between Measures of Financial and Customer Aspects in ...
https://ijnaa.semnan.ac.ir/article_4389_483.html
As is well known, the strategy dictates how an organization creates value for the stakeholders, customers and citizens. In fact, the strategy is the very factor that guides the organization in its journey towards realizing its vision. In this regard, four perspectives of Balanced Scorecard (BSC) articulate the strategic goals of organization in all respects. The cause-and-effect relationships, outlined in the form of a strategy map, are deemed as the formula for the organization's achievement. Causal relationships map the precise route for the strategy realization. Without such relationships, the organization has only to a set of individual financial and non-financial measures. For the first time in the banking industry of Iran, introduced key indicators of the banking industry and has been investigated the cause and effect relationship between to them. In addition, in the research the author's experiences in the banking industry have been considered so based on this research key variables were extracted from the system and converted to quantitative indicators. Finally, to ensure the validity of the data, the cause and effect relationship has been studied using granger causality method.Thu, 30 Apr 2020 19:30:00 +0100Present a Management Information System Deployment Model for Improving Food Security in ...

https://ijnaa.semnan.ac.ir/article_4412_483.html
The behavior of the financial market indices shows the randomness of the regions and the certainty of the public. Financial markets can be considered as non-linear dynamic systems that consider the interactions between factors in the process of immediate information analysis. The fractal market hypothesis assesses the stability and ability of financial markets to absorb shocks, in addition to testing efficiency. Numerous studies have tested the fractal market hypothesis in international financial markets, but a few studies has been denoted to the Tehran stock market. In this paper, the stock price of Tehran Stock Exchange companies has been evaluated during the period of 1393-1397 and in monthly intervals to determine whether these variables have multi-fractal characteristics in their behavior or not. An estimate of the modified R/S model has been employed to achieve the goal. The results of the above tests indicate that the stock price has a multi-fractal property and has a long-term memory in the period under review, which also implicates in the weak performance hypothesis. In fact, the random walk theory in stock prices has not been validated, and the past information can provide significant correlation with future stock price information.Thu, 30 Apr 2020 19:30:00 +0100Comparing Empirical Models with ANN in Estimation of Vibrations Resulted from Blasting, ...
https://ijnaa.semnan.ac.ir/article_4413_483.html
Blast hole drilling and blasting are from among cost effective and economic methods of crushing the rock in civil projects, tunneling, as well as surface and underground mining. Ground vibration is the most important undesirable effect of blasting and if not controlled, it can lead to many damages. The paper is aimed at studying and prediction of effects of vibrations resulted from blasting on structure of dam on Dareh-Baq River. For this purpose, four empirical equations along with Artificial Neural Network (ANN) have been used to the aim of achieving a highly accurate model to predict vibrations of ground. Also, level of vibrations created would be compared through existing standards. According to the above goals, 73 blasting cases in Dareh-Baq River Dam area have been studied and required parameters as for prediction have been measured. From 73% of information related to blasting has been used to obtain empirical equation and also provide appropriate model in ANN; and, the remaining 27% of information have been used to specify performance and evaluate accuracy level of various models, in comparison to real values. After evaluation of the results, it became clear that ANN is of highest accuracy for prediction of vibrations resulted from blast. Also, in consideration of recorded vibrations and their comparison to existing standards, as well as distance of dam on Dareh-Baq River from location of blasting, energy from vibrations created will be dissipated and no undesirable effect would be imposed on dam structure.Thu, 30 Apr 2020 19:30:00 +0100Stability and Periodic Nature of a System of Difference Equations

Additionally, we find out the invariant interval and periodic cycles of related system of difference equations.Thu, 30 Apr 2020 19:30:00 +0100Proposing a Novel Method for Increasing Security in the Network Communication
https://ijnaa.semnan.ac.ir/article_4421_483.html
Advances in quantum computer technology are threatening cryptographic systems based on mathematical complexity. As an alternative, quantum cryptography has been proposed and developed. Among the reported quantum cryptography systems, quantum key distribution (QKD) constitutes a symmetric key system that can securely distribute a secret key on a quantum channel. While there have been many studies on confidential communication using QKD, only a few of them address its application to the digital signature. In this paper, we propose a new digital signature method with public parameter and signature key through shared symmetric key from QKD. We also analyze the proposed plan from security.Thu, 30 Apr 2020 19:30:00 +0100Application of frames of subspaces in conjugate gradient method for solving operator equations

https://ijnaa.semnan.ac.ir/article_4431_483.html
Development is a serial changes within a complex dynamic system. During development, children reach and pass different stages while their dynamical development systems change their states. We hypothesize that in a developmental process, each stage can be accounted as a stable point and the system can be considered multi-stable due to different stages of development. We propose a dynamical model for language development which can explain some developmental disorders in this field, such as pragmatics impairment in autistic children.Sun, 31 May 2020 19:30:00 +0100Stability for comprehensive classes of analytic functions

https://ijnaa.semnan.ac.ir/article_3532_0.html
Let $A$ be a Banach algebra and $X$ be an arbitrary Banach $A$-module. In this paper, we study the second transpose of derivations with value in dual Banach $A$-module $X^{*}.$ Indeed, for a continuous derivation $D:Alongrightarrow X^{*}$ we obtain a necessary and sufficient condition such that the bounded linear map $Lambdacirc D^{primeprime}:A^{**}longrightarrow X^{***}$ to be a derivation, where $Lambda$ is composition of restriction and canonical injection maps. This characterization generalizes some well known results in cite{aef}.Tue, 25 Dec 2018 20:30:00 +0100Characterizations of the set containment with star-shaped constraints
https://ijnaa.semnan.ac.ir/article_3533_0.html
In this paper, we first give a separation theorem for a closed star-shaped set at the origin and a point outside it in terms of separation by an upper semi-continuous and super-linear function, and also, we introduce a $nu$-star-shaped-conjugation. By using this facts, we present characterizations of the set containment with infinite star-shaped 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 semi-continuous and radiant constraint, in a reverse star-shaped set, defined by a co-star-shaped constraint. These results have many applications in Mathematical Economics, in particular, in Utility Theory.Tue, 25 Dec 2018 20:30:00 +0100Common Fixed Point Theorems with Applications to Theoretical Computer Science

https://ijnaa.semnan.ac.ir/article_3946_0.html
In the last decades, nonlinear methods have been applied, in a large number of studies from the computational neuroscience field, to describe neuronal implementations of superior brain functions. Superior brain functions, called cognitive functions, control our behavior. Therefore, they should be assessed through evaluating individual performances in the experiments, using standard tasks, which represent the condition that cognitive functions are required. The mathematical models of cognitive functions, in neuronal implementation level, are based on real condition of standard cognitive tasks. However, it is not validated whether applied task conditions are appropriate to represent neuronal implementation of a cognitive function. Hence, as a case-study, we used a developed Bayesian Model to assess whether GoNoGo task is valid to be applied for neural measurement and modeling neural implementation of Inhibitory Control (IC). As GoNoGo is the most common task used for neural measurement of impaired cognitive function (IC) in ADHD, we fit the model to behavioral data of two groups of children/adolescents with and without ADHD. The results demonstrated that the model could simulated the behavioral data; and also the model parameters could differentiate the groups significantly. However, neural implementation of IC may not be represented through the rewarded condition of GoNoGo task. We concluded that before modeling neural implementation of cognitive functions, it is essential to apply nonlinear methods to validate current behavioral experiments computationally; or to design new model-based experiments for using in neural measurementsSat, 13 Jul 2019 19:30:00 +0100Investigating the dynamics of Lotka-Volterra model with disease in the prey and predator species
https://ijnaa.semnan.ac.ir/article_3947_0.html
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 transcritical bifurcation with parameter $a$ were investigated, where $a$ was regarded as predation rate. It wasfound 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.Sat, 13 Jul 2019 19:30:00 +0100ON THE SYSTEM OF DOUBLE EQUATIONS WITH THREE UNKNOWNS d+ay+bx+cx^2 =z^2 and y+z=x^2

https://ijnaa.semnan.ac.ir/article_3958_0.html
Here, we propose a practical method for solving nonsmooth convex problems by using conjugate gradient type methods. We present a modified HS conjugate gradient method, as one of the most remarkable methods to solve smooth and large-scale optimization problems. In the case that we have a nonsmooth convex problem, by way of the Moreau-Yosida regularization, we convert the nonsmooth objective function to a smooth function and then we use our method, by making use of a nonmonotone line search, for solving a nonsmooth convex optimization problem. We prove that our algorithm converges to an optimal solution under standard condition. Our algorithm inherits the performance of HS conjugate gradient method.Tue, 30 Jul 2019 19:30:00 +0100Character amenability of real Banach algebras

https://ijnaa.semnan.ac.ir/article_4473_483.html
In this paper, we introduce a new iterative algorithm of inertial form for approximating the solution of Split Variational Inclusion Problem (SVIP) involving accrective operators in Banach space. Motivated by the inertial technique, we incorporate the inertial term to accelerate the convergence of the proposed method. Under standard and mild assumption of monotonicity of the SVIP associated mappings, we establish the weak convergence of the sequence generated by our algorithm. Some applications and numerical example are presented to illustrate the performance of our method as well as comparing it with the non-inertial version.Thu, 30 Apr 2020 19:30:00 +0100Approximate Quartic Lie ∗-Derivations with perturbing terms

The aim of this paper is to introduce a new class of mappings called $(alpha, beta)$-Berinde-$varphi$-contraction mappings and to establish some fixed point results for this class of mappings in the frame work of metric spaces. Furthermore, we applied our results to the existence of solution of second order differential equations and the existence of a solution for the following nonlinear integral equation: begin{align*} x(t)=g(t)+int_a^bM(t,s)K(t,x(s))ds, end{align*} where $M:[a,b]times [a,b]tomathbb{R}^+,$ $K:[a,b]times mathbb{R}to mathbb{R}$ and $ g:[a,b]to mathbb{R}$ are continuous functions. Our results improve, extend and generalize some known results in the literature. In particular, our main result is a generalization of the fixed point result of Pant cite{ran}.Tue, 30 Jun 2020 19:30:00 +0100An extension and refinement of Hermite-Hadamard inequality and related results
https://ijnaa.semnan.ac.ir/article_4492_483.html
In this paper we establish an extension of Hermite-Hadamard inequality and as a result we obtain the Hermite-Hadamard inequality for fractional integral and logarithmic integral. Also we get a new refinement of it. Some examples are given.Thu, 30 Apr 2020 19:30:00 +0100Dynamics of a second-order system of nonlinear difference equations
https://ijnaa.semnan.ac.ir/article_4493_483.html
In this paper, we investigate the equilibrium points, stability of two equilibrium points, convergences of negative equilibrium point, periodic solutions, and existence of bounded or unbounded solutions of a system of nonlinear difference equations x_{n+1}=x_{n-1}y_{n}-1,y_{n+1}=y_{n-1}x_{n}-1 n=0,1,..., where the initial values are real numbers. Additionally we present some numerical examples to verify our theoretical results.Thu, 30 Apr 2020 19:30:00 +0100Coincidence point results for graph preserving hybrid pair of mappings
https://ijnaa.semnan.ac.ir/article_4495_483.html
We analyze the existence of coincidence points for hybrid pair of mappings defined on b-metric spaces endowed with a digraph G. Our main result is an extension of the well-known Nadler's fixed point theorem. Finally, we present a coincidence point theorem for mappings satisfying a general contractive condition of integral type. We include some examples to examine the validity of our results.Thu, 30 Apr 2020 19:30:00 +0100
