Ultra-Low Cost Full Adder Cell Using the nonlinear effect in Four-Input Quantum Dot Cellular Automata Majority Gate
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.

Providing Optimal Decision-Making Function for Efficient Selection of A Contractor Using PSO Algorithm in MAPNA
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.

Measuring the Efficiency of Banks' Performance Based on Economic Policies Using Data Envelopment Analysis
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.

To Do or Not to Do: Game Theory and Literature
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.

The Spatial Modeling and Analysis of Ancient Sites of Khonj County Using Hybrid AND-GIS Analysis
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.

An Intelligent Model to Predict the Development Time and Budget of Software Projects
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%.

Analysis of the Causal Relationships Between Measures of Financial and Customer Aspects in Balanced Scorecard
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.

2-D Modeling of Bulk Heterojunction Solar Cells With a Gaussian Shape in Donor-Acceptor Interface as Morphology
In this work, we presented numerical modeling for the bulk heterojunction polymer solar cells (BHJ) based on the finite difference method to obtaining the BHJ characteristics. Our model for the BHJ, where the electron donor and acceptor materials are mixed in a solution, is two separate domains with gaussian shape interface. In this model we consider a two-dimensional geometry of thickness L on y-axis and periodic along x-axis. We assume that the rate of exciton generation to be homogenous throughout device. Some of obtained characteristics are the density of electrons and the density of the holes, current density, open circuit voltage and short circuit current density.

Scalable frames in Tensor Product Of Hilbert Spaces
Tight frames are very similar to orthonormal bases and can be used as a good alternative to them. Scaling frames are introduced as a method to transform a general frame to a tight one. This paper investigates in under what conditions the tensor product of two frames is a scalable frame. We expand some results concerning frame operations of eigenvalues to tensor product of Hilbert spaces. Finally, we will show that if one of the frames is scalable, better conditions are obtained for the approximation of tensor product of frames that is not scalable.

Analysis of Weak Performance Hypothesis, Multi-Fractality Feature and long-Term Memory of Stock Price in Tehran Stock Exchange
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.

Comparing Empirical Models with ANN in Estimation of Vibrations Resulted from Blasting, Dareh-Baq Dam
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.

Proposing a Novel Method for Increasing Security in the Network Communication
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.

Multi-stability in a Dynamic Model of Language Development
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.

Character amenability of real Banach algebras
Let $ (A,\| \cdot \|) $ be a real Banach algebra. In this paper we first introduce left and right $\varphi$-amenability of $A$ and discuss the relation between left (right, respectively) $\varphi$-menability and $\overline{\varphi}$-amenability of $A$ for $\varphi\in\triangle(A)\cup\{0\}$ where $\overline{\varphi}\in\triangle(A)$ is the conjugate of $\varphi$. Next we show that $A$ is left (right, respectively) $\varphi$-amenable if and only if $A_{\mathbb{C}}$ is left (right, respectively) $\varphi_{\mathbb{C}}$-amenable, where $A_{\mathbb{C}}$ is a suitable complexification of $ A $ and $\varphi_{\mathbb{C}}\in\triangle(A_{\mathbb{C}})$ is the induced character by $\varphi$ on $A_{\mathbb{C}}$. In continue, we give a hereditary property for 0-amenability of $A$. We also study relations between the injectivity of Banach left $A$-modules and right $\varphi$-amenability of $A$. Finally, we characterize the left character amenability of certain real Banach algebras.

Inertial approximation method for split variational inclusion problem in Banach spaces
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.

A series of refinements on the Young and reverse Young inequalities through a recursive algorithm
In this article, we present a recursive algorithm to obtain a series of refinements of the classical Young inequality. These inequalities approach to equalities when the number of the iteration in the recursive algorithm tends to infinity. Also these refinements applied to establish some improved reverse Young and matrix Young inequalities with Hilbert- Schmidt norm.

Korovkin type Approximation of Abel transforms of q-Meyer-König and Zeller operators
In this paper we investigate some Korovkin type approximation properties of the $q$-Meyer-König and Zeller operators and Durrmeyer variant of the $q$-Meyer-König and Zeller operators via Abel summability method which is a sequence-to-function transformation and which extends the ordinary convergence. We show that the approximation results obtained in this paper are more general than some previous results. We also obtain the rate of Abel convergence for the corresponding operators. Finally, we conclude our results with some graphical analysis.

Endpoint results for weakly contractive mappings in $\mathcal{F}$-metric spaces with application
Many researchers have provided certain interesting results for endpoints of some contractive multivalued mappings in metric spaces. In this paper, we introduce $\alpha$-$\zeta$-contractive multivalued mappings in $\mathcal{F}$-metric spaces and establish some endpoint results in this framework. An illustrative example is given to elaborate the usability of our main result. In the sequel, we give some endpoint theorems for Suzuki-type contractive multivalued mappings and provide an application to integral equations.

On some fixed point results for $(\alpha, \beta)$-Berinde-$\varphi$-Contraction mapppings with applications
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 $M:[a,b]\times [a,b]\to\mathbb{R}^+,$ $K:[a,b]\times \mathbb{R}\to \mathbb{R}$ 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}.

A Novel Method for Detection of Fraudulent Bank Transactions using Multi-Layer Neural Networks with Adaptive Learning Rate
Fraud refers to earn wealth including property, goods and services through immoral and non-legal channels. Fraud has always been in action and experiences an increasing trend worldwide. Fraud in financial transactions not only leads to losing huge financial resources, but also leads to reduction in trust of customers on using modern banking systems and hence, reduction in efficiency of the systems and optimal management of financial transactions. In recent years, by emerging new tech- nologies of banking industry, new means of fraud are discovered. Although a new information system carry advantages and benefits, new opportunities are made for fraudsters. The applications of fraud detection methods encompasses detection of frauds in an organization, analysis of frauds and also user/customer behavior analytics in order to predict future behavior and reduce the fraud risks. In recent decades, employing new technologies in management of banking transactions has risen. Banks and financial institutions inevitably migrated from traditional banking to modern online banking to provide effective services. Although, the use of online banking systems improves the management of financial processes and speeds up services to customers of institutions, but some issues would also be carried. Financial frauds is one of the issues which organizations seek to prevent and reduce effects. In this paper, a novel machine learning based model is presented to detect fraud in electronic banking transactions using profile data of bank customers. In the proposed method, transactional data from banks are leveraged and a multi-layer perceptron neural network with adaptive learning rate is trained to prove the validity of a transaction and hence, improve the fraud detection in elec- tronic banking. The proposed method shows promising results compared with logistic regression and support vector machines.

Investigating the relationship between product market competition and diversion of eﬃcient investment using linear and nonlinear models
Usually, a set or combination of investments is maintained in a company along with investors in the ﬁnancial markets often considering a reduction in the diversion of investment eﬃciency. In view of the factors aﬀecting diversion of investment eﬃciency along with the use of linear and non-linear models (linear fractional, linear plus linear fractional), the relationship between product market competition and control variables with diversion from investment eﬃciency has been investigated to help reduce diversion of the investment eﬃciency. To achieve this objective, the data of 110 companies listed in Tehran Stock Exchange during the period 2010 to 2015 was used. The results obtained revealed that the non-linear models (linear plus linear fractional) provides a more precise explanation of the impact of the product market competition on the diversion of investment eﬃciency.

New Approximation Techniques for Solving Variational Inclusions Problem via SP Iterative Algorithm with Mixed Errors for Accretive Lipschitzian Operators
Using diﬀerent convergence techniques and under the lack of parametrical restrictions, the convergence and stability results of SP iterative algorithm with mixed errors for accretive Lipschitzian operators in Banach spaces are established. We propose numerical examples to verify eﬀectiveness of new convergence techniques and to show that SP iterative algorithm with mixed errors converges more eﬀectively than the Mann, Ishikawa and Noor iterative algorithms with mixed errors. Moreover, new iterative approximation of solution for variational inclusion problem in Banach spaces is investigated by using SP iterative algorithm with mixed errors for accretive Lipschitzian operators. Our results are improvement and generalization of results of Kim[15], Gu[10], Gu and Lu[11], Chugh and Kumar[7] and many others in the literature.

Risk Assessment Strategies in Credit Process of Iranian Banking System Case study: Banks listed in Tehran Stock Exchange
Purpose and theoretical framework: This applied-descriptive research has been performed to the aim of identifying fraud risk assessment strategies in credit process of Iranian banking system. Statistical population of the research includes banks listed in Tehran Stock exchange. Design and methodology: To collect data, library and field studies have been used through distribution of questionnaire among participants i.e. university experts, as well as experts in the banking field and risk management. To analyze data, descriptive and inferential statistical tests such as factor analysis and structural equation modeling (SEM) have been used. Findings: In general, the research findings show that fraud risk assessment strategies in credit process have considerable effect on performance of operational risk management in credit process of Iranian banking system. Therefore, the results have been indicating that fraud risk assessment strategies in credit process of Iranian banking system have to be taken into consideration by economic activists, investors, government, and supervising institutions. Implications: Therefore, with consideration of the results from present research it is proposed that in credit field of banks, more attention would be paid to the issue of various types of fraud risks; and, future researchers are suggested to study the role played by internal control and corporate governance on operational risk management in credit process of banks listed in Tehran Stock Exchange, and to compare their results with those of present research for analysis. It goes without saying that, most important restrictions existing in this research and considered in interpretation of results include: low number of researches with similar subject, including those performed inside the country and out of it due to novelty of the subject.
