https://ijnaa.semnan.ac.ir/article_8531.html
In this study, at first a new polynomial rank transmutation is proposed. Then, a new cubic rank transmutation is introduced by simplifying the set of transmutation parameters in order to improve its usefulness in statistical modeling. The probability density function, moment generating function, survival and hazard rate functions of cubic rank transmuted distribution are examined. Moreover, existence of stochastic, hazard rate and likelihood ratio orderings are investigated with respect to the baseline distribution. The processes of estimating of the parameters with maximum likelihood and EM algorithm are mentioned. The modeling performance of the distribution is showed by considering real data sets obtained from different areas.A new subclass of analytic functions and some results related to Booth lemniscate

https://ijnaa.semnan.ac.ir/article_8838.html
One of the most important financial decisions is the way of financing economic enterprises, which plays a significant role in the continuation and growth of their profitability. The ability of companies to obtain financial resources inside and outside the company in order to invest and implement development plans is one of the main factors in the growth of profitability of companies. Active commercial companies also need financial resources to develop the market, modernize technology, increase product quality, produce new products, and grow their profitability. Also, investors in economic projects will need capital and money to implement their plans. One of the most important financial decisions is the way of financing economic enterprises, which plays a significant role in the continuation and growth of their profitability. The ability of companies to obtain financial resources inside and outside the company in order to invest and implement development plans is considered one of the main factors in the growth of profitability of companies. Companies often when they need new financial resources, take advantage of the company's internal resources, including accumulated profits and reserves, or through receiving loans and credits from banks and financial and credit institutions or issuing shares and other types of debt securities. capital, they meet their needs. Therefore, this research deals with the design of the financing model for small and medium knowledge-based businesses and examines and discusses the theories of experts.Examining the impact of information technology and IT on independent auditing in Iran
https://ijnaa.semnan.ac.ir/article_8841.html
The statistical population in this research includes financial managers, audit managers, audit supervisors, book authors, university faculty members, doctoral students and researchers of the research group of the audit organization in Garmsar Industrial Town, who are researching the topic (the impact of information technology on the qualitative characteristics of accounting information). The results of the regression analysis of the final stage of the path analysis process show that the coefficient of variable effects of investment in information technology is equal to 0.702 and its significance level is equal to 0.000, which indicates the positive and significant effects of information technology on the lack of focus in the decision-making process. It is at the 99% confidence level. The value of the F statistic of the model is 37.8 and its significance level is 0.000, indicating the reliability of the model at the 99% confidence level. The coefficient of determination of the model is also equal to 0.493 and it states that 49.3 percent of the changes in the variable of lack of concentration in decision-making are explained by transitory capital in information technology. In a changing world, reaching such a level of skill is not a dream; Rather, it is a duty. In addition to auditing, the auditor&rsquo;s job includes predicting changes in the direction of information technology and the impact that these changes and their consequences may have on business goals.Qualifications and stationarity for nonsmooth multiobjective problems with switching constraints

https://ijnaa.semnan.ac.ir/article_8784.html
Social responsibility is a commitment causing managers of private sector business organizations to consider the whole community's well-being in their profit-making decisions. Organizations' performance evaluation criteria have evolved, and social and environmental responsibilities have become necessary for the long-term activities of organizations. This research uses Delphi forecasting methods, AHP ranking, questionnaires, and PLS through a comprehensive framework to analyze the effect of social responsibility disclosure components on company value creation. A content analysis was performed on the board reports of Iranian companies to examine the current status and the social dimension disclosure level in Iranian companies. To this purpose, a sample of active and large companies of the Tehran Stock Exchange, including about 106 cases from the energy, refining, and petrochemical industries, have been used. The results obtained from the path analysis and the desired indicators of the structural model fit supported the significance, explanation, and proper justification of corporate responsibility's social dimension disclosure components. In addition, a significant relationship was found between social responsibility disclosure and value creation.Designing an information asymmetry model with emphasis on the role of financial and managerial criteria
https://ijnaa.semnan.ac.ir/article_8840.html
The main problem of the current research is the absence of a suitable measure to measure the information asymmetry between managers who forecast profits and statistical analysts who forecast profits through statistical methods. The lack of a suitable criterion for measuring information asymmetry between managers who forecast earnings and statistical analysts who forecast earnings through statistical methods is the main problem of the present study. The present study aims to provide a model of information asymmetry with emphasis on the role of financial and managerial criteria; The present research is a qualitative and quantitative research (mixed method) which is based on the purpose of applied research. In order to prepare and formulate theoretical bases for reviewing research records, the library method is used, and also for collecting information in order to measure and identify indicators and modeling, the field method is used. To analyze the data, first after identifying the dimensions and variables of financial and managerial criteria of information symmetry, to eliminate irrelevant factors and classify them with the help of factor analysis, this work was done and 5 main dimensions were identified, which are: Corporate profit forecast is 2- corporate governance, 3- capital market, 4- return on capital, 5- managerial characteristics of the company.Global asymptotic stability of a networked fractional SIR model
https://ijnaa.semnan.ac.ir/article_8648.html
In this paper, we consider a networked fractional SIR model. After proving the existence and uniqueness of the solution, we obtain the basic reproduction number, the disease-free equilibrium point and the endemic equilibrium point. By constructing the Lyapunov function, we show that the endemic equilibrium is globally asymptotically stable when the basic reproduction number is greater than 1, and the disease-free equilibrium is globally asymptotically stable when the basic reproduction number is less than 1. Finally, numerical simulations are carried out to verify these theoretical results. Thus, the stability theory of Laplacian diffusion is extended to the graph Laplacian model.The constructional model of the effects of pricing strategies on the exporting petrochemical products in Iran
https://ijnaa.semnan.ac.ir/article_8849.html
This study presents a constructional model that explores the effects of pricing strategies on exporting petrochemical products in Iran. The model is based on a comprehensive review of existing literature and case studies and input from industry experts and stakeholders. The constructional model identifies the main pricing strategies that petrochemical companies in Iran use, such as maximizing profits, increasing market share, and maintaining a certain level of quality. The model also considers the impact of external factors such as demand elasticity, market competition, and regulatory constraints on pricing decisions. Using the constructional model, this paper analyzes the advantages and disadvantages of different pricing strategies in the Iranian petrochemical industry. The model also simulates the impact of different pricing strategies on various stakeholders, including producers, consumers, and the Iranian government. The results of the constructional model suggest that while pricing to maximize profits may lead to short-term gains, it can limit a company's ability to compete in the global market. On the other hand, pricing to increase market share can lead to long-term growth but may require significant investment in research and development. The model also highlights the importance of considering external factors such as demand elasticity and regulatory constraints when making pricing decisions. For example, demand for petrochemical products in Iran may be highly elastic, meaning that small price changes can lead to large changes in demand. Additionally, regulatory constraints such as trade agreements and environmental regulations can significantly impact pricing decisions in the Iranian petrochemical industry. Overall, this paper provides a useful constructional model for analyzing the effects of pricing strategies on exporting petrochemical products in Iran. The findings of this paper can help petrochemical companies in Iran make strategic pricing decisions that take into account both internal and external factors, to ensure their long-term success in the global market. The variables of the study are restrictions of entry into the export market, penetration strategy, market development strategy, and opportunity creation, all of which have effects on product export. Here, the following features are described, penetration strategy (importance coefficient: 0.95), market development strategy (importance coefficient: 0.94 opportunity creation (importance coefficient: 0.9), and the restrictions of entry into the export market (importance coefficient: 0.8). The Alpha Cronbach of the two questionnaires are 0.817, 0.814, in turn, that indicates the appropriate validity.Hyers-Ulam stability of a quadratic-additive functional equation in non-Archimedean fuzzy $\varphi$-2-normed spaces
https://ijnaa.semnan.ac.ir/article_8658.html
In this &nbsp;work, we &nbsp;introduce the following &nbsp;quadratic-additive functional equation\begin{align*}&amp;\psi\left(\sum_{a=1}^{n} &nbsp;v_{a}\right)+\sum_{a=1}^{n}\psi\left(-v_{a}+\sum_{b=1;a\neq b}^{n} v_{b}\right)\nonumber \\= &amp;\left(n-3\right) \sum_{1\leq a&lt;b\leq n}\psi\left( v_{a}+ &nbsp;v_{b}\right)-\left(n^{2}-5n+2\right)\sum_{a=1}^{n} \left[ \frac{\psi(v_{a})+\phi(-v_{a})}{2}\right] -\left(n^{2}-5n+4\right)\sum_{a=1}^{n} &nbsp;\left[\frac{\psi(v_{a})-\phi(-v_{a})}{2}\right]\end{align*}where $n$ is a nonnegative integer in $\mathbb{N}-\{0,1,2\}$, and we prove the &nbsp;Hyers-Ulam stability of the quadratic-additive functional equation in non-Archimedean fuzzy $\varphi$-2-normed space by utilizing two different techniques.The investigation of variant vaccination models in Iran
https://ijnaa.semnan.ac.ir/article_8526.html
Kermack-McKendrick-type epidemic models are commonly used for modeling epidemic diseases. In this study, we have proposed a Kermack-McKendrick-based model to elucidate the impact of COVID-19 vaccination on the spread of the virus in Iran. This model serves as an endemic assessment tool, tailored to fit reported data in Iran, for gauging the potential population-level effects of the COVID-19 vaccine. It's important to note that COVID-19 vaccines do not guarantee complete protection against the disease. A vaccinated person may still become infected, highlighting the necessity of continuous vaccination while an individual is in the system. To address this, we considered two models&mdash;one with only one strain and the other containing two strains. We hypothesize that the vaccine results in complete immunization against one strain while conferring partial immunization against the other. To explore this, we consider two scenarios. In the first scenario, we assume that the vaccine does not provide complete immunity, and individuals may become infected again after vaccination. In the second scenario, a dual-strain model is considered, positing that individuals, when vaccinated, remain immune to the strain present in the vaccine, but are susceptible to another strain for which the vaccine provides partial protection. However, this other strain may still lead to infection in individuals. The analysis of the proposed models revealed that where the prevalence rate, or the basic reproduction number (R0) - an index measuring the spreading potential of a pathogenic agent and the average number of individuals each infected person can potentially transmit the infectious agent to susceptible individuals - has a direct correlation with vaccination. Therefore, to assess the extent of vaccine efficacy, this indicator is employed, with a lower prevalence rate being the targeted outcome.A newly proposed super-twisting backstepping sliding mode controller
https://ijnaa.semnan.ac.ir/article_8661.html
The chattering phenomenon has been one of the most important controlling challenges in recent years, and efforts have been made to eliminate or control this phenomenon effectively, with various control strategies. In this article, a new super-twisting back-stepping sliding mode controller is proposed and to validate the performance of this controller, the outcomes of some well-known techniques are compared, in two aspects reducing tracking error and removing the chattering phenomenon. Also, a comparative analysis between control methods such as sliding mode, &nbsp;feedback linearization and back-stepping control has been done in the sense of stability and convergence. The model discussed in this article is a non-linear, highly unstable system of the inverted pendulum. The results of applying the proposed controller on an inverted pendulum are compared in terms of the tracking speed, convergence time, error and chattering reduction. In addition, the stability analysis of the closed-loop system is presented according to the Lyapunov theorem. The results clearly show the efficiency of the proposed method not only in terms of stability and convergence improvement but also in reducing unwanted chattering.Presenting a model for improving the interaction between the auditor and the client based on grounded theory
https://ijnaa.semnan.ac.ir/article_8772.html
The purpose of the current research is to provide a model for improving the interaction between the auditor and the client based on the grounded theory. In this regard, the factors of interaction between the auditor and the client were explained and the main components identified in order to improve the interaction between the auditor and the client were presented. Finally, the identified factors were ranked using the Friedman test. In order to extract effective factors for improving the interaction between the auditor and the employer, the foundation's data approach was used. Also, due to the lack of a coherent model in the literature related to improving the interaction between the auditor and the client in Iran, a semi-structured interview with experts was also used to cover the weak points of the existing theoretical foundations and to reach the stage of persuasion. The results of the foundation's data approach showed that the research model based on improving the interaction between the auditor and the client can be classified into 6 main categories, causal conditions, background conditions, strategies, intervention conditions and consequences. The results of Friedman's test indicated that the variables 1. the timeliness of providing information by company managers to auditors; 2. Acquaintance of auditors with the software used in preparing financial reports; 3. Internal audit; 4. activity history of auditors; 5. Reducing the anxiety of the audit staff, respectively, has a higher priority as an effective factor in improving the interaction of auditors with business owners. Also, it was found that the variables 1. tenure of auditors; 2. The size of the employer's company; 3. The presence of more non-commissioned directors in the structure of the board of directors of companies; 4. Mandatory rotation of auditors; 5. The acquaintance of the audit team members with updated and used software was less important from the point of view of the respondents. The findings of this research can help solve the complexities of the interaction between the auditor and the employer. The current research is based on the idea that there are factors that can improve this interaction and some factors cannot affect this interaction.Nonexistence of sub-elliptic critical problems with Hardy-type potentials on Carnot group

Using the Pohozaev-type arguments, we prove the nonexistence results for sub-elliptic problems with critical Sobolev-Hardy exponents and Hardy-type potentials on the Carnot group.Financial timeseries prediction by a hybrid model of chaos theory, multi-layer perceptron and metaheuristic algorithm
https://ijnaa.semnan.ac.ir/article_8796.html
Many researchers proved that hybrid models have better results in comparison with independent models. A combination of different methods could enhance the accuracy of time series prediction. Hence, this research used the hybrid of three methods of chaos theory, multi-layer perceptron and metaheuristic algorithm to increase the power of the model forecasting. Artificial neural networks have properly considered complex nonlinear relations and are good comprehensive approximators. Multi-objective evolutionary algorithms such as multi-objective particle swarm optimization are good at solving multi-objective optimization issues. This algorithm organized the combination of parent and children populations by elitist strategy, decreased the messy comparing factors to improve the solution variety and avoided to use of niche factors. Chaos theory controls the complexities of stochastic systems. So, this research offers Tehran Stock Exchange Index (TSEI) prediction by a hybrid model of chaos theory, multi-layer perceptron and metaheuristic algorithm. The results show that in perceptron-based mode, RMSE measures are gradually increased in all intervals. The continuous decrease of RMSE shows that the perceptron-based model could show consistency with the whole data flow. This matter could offer a better learning and consistency process by perceptron-based models to predict stock prices, as this type of learning could apply more experiences for forecasting future behaviour in order to change the system content.The multi-decision-making problem in the recruitment process using penta-partitioned neutrosophic distance measure
https://ijnaa.semnan.ac.ir/article_8680.html
In this article, we introduce some different distance measures on penta-partitioned neutrosophic sets and some distance measures satisfy axioms of metric. We also formulate a new methodological approach to solve the multi-criteria decision-making problems, in which the suitable decision is by ranking the average of the proposed penta partitioned neutrosophic distance measure for the alternatives to the criteria under certain conditional criteria. Further, we apply these distance measures to a multi-criteria decision-making problem (MCDM) for the best employee selection to recruit for a post. The comparison is finally made between the proposed distance measures and the final decisions are the same in all penta-partitioned neutrosophic distance measures.Analysis of student's understanding of the concept of derivative with a discrete approach
https://ijnaa.semnan.ac.ir/article_8541.html
This paper studies the engineering students' understanding of derivatives with a discrete approach using sequences introduced by Weigand (2014). This approach proposes a step-by-step method of difference sequence for functions defined on Z and Q. This concept was taught as part of a mathematics course in an engineering college at an Iranian university. HomeWorks with questions based on derivatives with a discrete approach were constructed and performed for the participants. Their written answers, which were used to explore the students' mental structures of these mentioned concepts, were analyzed using APOS (Action-Process-Object-Schema) theory. We performed interviews so that the students could explain their written answers. The results show that students tend to adopt an algorithmic approach when solving derivative problems and students' understanding of the meaning of derivative with a discrete approach was mainly procedural. Also according to the observed mental structures, a suggested genetic decomposition for the derivative with a discrete approach is presented.On fuzzy C*-algebras

https://ijnaa.semnan.ac.ir/article_8850.html
The process of social evolution and progress and the speed of this evolution depend on many variables, one of which is technology. Some believe that technological advances are changing many aspects of daily life. At present, in many developing countries, including our country, Iran, organisations are showing a great desire to use and use these information technologies. Given that in the future, no factor such as information technology will be able to change the design of organisations. Research in this field will be necessary, so the purpose of this research is to investigate the impact of technology introduction on administrative bureaucracies. The statistical population in a small stage includes all employees of the Ministry of Culture and Islamic Guidance, whose number is 800 people. The sampling method in this study is available. 260 people are using Cochran's formula. Also, to evaluate the variables and measure them in the field, a researcher-made questionnaire has been used. 48.866 and a path coefficient of 0.91 have a significant effect. The introduction of technology has had a significant effect on research strategies in the staff of the Ministry of Culture and Islamic Guidance with test statistics of 2.933 and path coefficient of 0.408 and research intervention factors on research strategies in employees of Ministry of Culture and Islamic Guidance with test statistics of 3.596 The path coefficient has a significant effect of 0.470 and the research factors have a significant effect on research strategies in the staff of the Ministry of Culture and Islamic Guidance with Azman statistics of 4.253 and the path coefficient of 0.556. Finally, the introduction of technology to administrative bureaucracy and the path coefficient of 0.843 has a significant effect.Stability of (1,2)-total pitchfork domination
https://ijnaa.semnan.ac.ir/article_8684.html
Let $G=(V, E)$ be a finite, simple, and undirected graph without an isolated vertex. We define a dominating &nbsp;$D$ of $V(G)$ as a total pitchfork dominating set if $1\leq|N(t)\cap V-D|\leq2$ for every $t \in D$ such that $G[D]$ has no isolated vertex. In this paper, the effects of adding or removing an edge and removing a vertex from a graph are studied on the order of minimum total pitchfork dominating set $\gamma_{pf}^{t} (G)$ and the order of minimum inverse total pitchfork dominating set $\gamma_{pf}^{-t} (G)$. Where $\gamma_{pf}^{t} (G)$ is proved here to be increasing by adding an edge and decreasing by removing an edge, which are impossible cases in the ordinary total domination number.New representations of the generalized uniform fuzzy partitions: Generalized normal case
https://ijnaa.semnan.ac.ir/article_8539.html
In this research, new representations of basic functions are proposed based on the new types of fuzzy partition and a subnormal generating function. The generalized uniform fuzzy partitions in subnormal case, i.e. in case a generating function K is not normal (generalized normal case), and simpler form of fuzzy transform (FzT) components based on these new representations of the generalized uniform fuzzy partitions are indicated. The main properties of a new uniform fuzzy partition are suggested. New theorems and lemmas are proved.An application of mixed monotone operator on a fractional differntial equation on an unbounded domain
https://ijnaa.semnan.ac.ir/article_8687.html
This paper provides sufficient conditions that guarantee the existence of positive solutions to a boundary value problem of a nonlinear fractional differential equation on the half line. Our analysis takes advantage of a theory on cones and mixed monotone operators combined with the diagonalization method. The paper also contains some examples that are numerically solved by the Adomian Decomposition Method.Explaining the role of banks' market power (competition) on liquidity creation in the condition of oil price shock
https://ijnaa.semnan.ac.ir/article_8848.html
The current paper aims to explain the role of banks' market power in creating liquidity during an oil price shock. The sample population of this study includes Iran's commercial and specialized banks whose information is available from 2011 to 2021. To test the research hypotheses based on the multiple regression method, the data were analyzed using Eviews 10 software after checking the data's validity and the regression analysis assumptions. The Lerner index was used to measure the bank market power variable as the research's independent variable. The inverted index of stable funding net ratio based on Basel 3 liquidity requirements was used to measure the study's dependent variable, liquidity creation. Furthermore, the negative changes in oil prices were considered oil price shocks, which is the moderating variable of the present study. The results showed that bank market power has a positive and significant effect on the creation of bank liquidity at the confidence level of 90%, which means that with a high market power, banks tolerate more liquidity risk. Besides, the results indicate that the oil price shock has a negative and significant effect on bank liquidity creation at the level of 90\%; Oil price shock does not influence the relationship between bank market power and liquidity creation. Therefore, banks with high market power tolerate more liquidity risk, and market power can significantly impact economic growth through its effect on creating liquidity.Incomplete inverse problems for the Sturm-Liouville type differential equation with the spectral boundary condition
https://ijnaa.semnan.ac.ir/article_8689.html
In this study, we examine the inverse problem for the differential equation of the Sturm-Liouville type with the spectral boundary condition in the finite interval. Using Lieberman-Hochstadt's method, we show that if $p(x)$ is prescribed on the half interval &nbsp;$\left(\frac{\pi}{2},\pi\right)$ &nbsp;then a single spectrum suffices to determine $p(x)$ on $(0,\pi)$. Moreover, applying Gesztesy-Simon's method, we demonstrate that if $p(x)$ &nbsp;is assumed over the given segment $[\pi/2(1 - \theta), \pi]$ where $\theta \in (0, 1),$ a finite number of the spectrum is enough to give $p(x)$ on $(0, \pi)$.The relationship between social responsibility and public acceptance in local communities of mines, with the mediating role of environmental responsibility and the value of mines
https://ijnaa.semnan.ac.ir/article_8851.html
The purpose of the current research was to investigate the relationship between social responsibility and general acceptability in the local communities of mines, with the mediating role of environmental responsibility and the value of mines. Therefore, in terms of the purpose of this research, except for applied research, and in terms of collecting findings, it was done with the correlation method based on structural equations. The statistical population of this research included the employees of Asfij Coal Company in 2024. Several 189 people were selected as the research sample based on the table of Karjesi and Morgan by random sampling method. The research findings were collected using social responsibility questionnaires of Mignagni and Ferrell [22], the social acceptance of Carroll [8], the environmental responsibility of Carroll [9] and the organizational values of Cameron and Quinn [7]. The validity of the questionnaires was calculated using confirmatory factor analysis and their reliability was calculated using Cronbach's alpha test. The research data were analyzed using descriptive and inferential statistics, structural equation modelling and the Sobel test in the environment of SPSS and SmartPLS software. The findings of the research showed that the effect of the variable value of mines on public acceptability ($F=0.61$), the effect of the variable of social responsibility on the value of mines ($F=0.454$), on environmental responsibility ($F=0.288$) and public acceptability ($F = 0.350$) and the impact of the environmental responsibility variable on the value of mines ($F = 0.519$) and public acceptance ($F = 0.150$) is positive and significant. In addition, Sobel's statistics showed that the indirect effect of social responsibility on public acceptability was equal to ($\beta=0.301$) due to environmental responsibility and ($\beta=0.287$) due to the value variable of mines. Therefore, it shows that these effects are positive. According to the findings of this research, it is suggested that Asfij Coal Company should always emphasize its environmental and social responsibility towards local communities to gain public acceptance and maintain the value of its mine.Qualitative study for the p-Laplacian type diffusion-convection equation with the effect of an absorption source

https://ijnaa.semnan.ac.ir/article_8856.html
Noise traders cause severe fluctuations and deviation of asset values from their intrinsic value; thus, this article designs an optimal investment model based on the parameters of predicting stock returns and noise trader risk factors. This is an applied post-event paper. In this article, first, the stock returns predicting parameters are obtained followed by the noise traders' risk factors obtained through behavioural error or the beta difference in transactions, according to the combined regression model or models, which are the results of the risk factors. Then, noise traders and stock return predictor variables were designed and tested using econometric software, including Eviews9 software and Matlab algorithmic models. The statistical population of this research includes all companies admitted to the Tehran Stock Exchange, whose shares were traded until March 19, 2020. Also, in this research, PCA, GSADF, and logit methods were used to determine the impact of noise traders in determining the incidence of the bubble used in the Tehran Stock Exchange. The research findings show that noise traders have a positive and significant effect on the occurrence of a bubble, and an increase of one unit of optimistic sentiments and optimistic sentiments with a break in the stock market increases the probability of a bubble occurrence.Existence of a solution for a strongly nonlinear elliptic perturbed problem in anisotropic Orlicz-Sobolev space

https://ijnaa.semnan.ac.ir/article_8744.html
In this article, firstly we investigate some properties of the boundary curvature of the numerical range. In the next, we define $M(T)$ as the smallest constant such that $dist(\lambda,\sigma(T))\leq M(T) R_\lambda (T),$ for all $\lambda \in \partial W(T)$, where $R_\lambda (T)$, the radius curvature at the point $\lambda$, is defined. Also, we investigate for non-convexoid $T$, $M(T)=\sup\frac{dist(\lambda,\sigma(T))}{R_{\lambda}(T)}$, where the supremum on the right-hand side is taken along all points $\lambda\in \partial W(T)$ with finite non-zero curvature. Finally, the value of $M(T)$ will be calculated for the self-inverse operators.Improved Coot optimization algorithm with Levy flight for shape and size optimization of Truss structures
https://ijnaa.semnan.ac.ir/article_8852.html
The convergence issues and getting trapped in local optimal points are two of the major concerns in the field of optimization. For this purpose, improving the standard algorithms to reach better performance in facing complex optimization problems is considered as one of the main challenges in the field of optimization. In this paper, the performance improvement of metaheuristic algorithms is considered while the applicability of the improved and standard algorithms is evaluated through the weight optimization problem of truss structures. For this purpose, the recently proposed Coot optimization algorithm is utilized as the main algorithm which is inspired by different movement types of Coot birds in the water in order to reach food supplies. Regarding the fact that the standard Coot algorithm utilizes random movement in the main search loop, a new improving methodology is utilized in this paper by replacing these random movements with Levy flight as a stochastic procedure with step length defined by levy distribution. The performance of the standard and improved Coot optimization algorithms is investigated in dealing with the problem of optimizing the shape and size of truss structures. Based on the best and statistical results, it is concluded that the improved Coot algorithm is capable of providing better results that the standard Coot algorithm while the capability of the improving methods in increasing the overall performance of the standard algorithm is demonstrated.Some properties of bicomplex holomorphic functions

https://ijnaa.semnan.ac.ir/article_8866.html
Childhood is the most sensitive and influential period of every person's life, because in childhood and adolescence, different physical and psychological dimensions of the child are forming and interacting. Therefore, maintaining and ensuring the growth and physical and mental health of the child is of great importance. This is despite the fact that when these children are subjected to violence, it will have negative effects on the child and the society. In the meantime, sexual violence against children by pedophiles in different ways is a serious issue for all countries that requires considerations at the national and transnational levels. Therefore, in this study, identifying the characteristics of pedophile people and underlying factors in becoming a pedophile and becoming a victim in this phenomenon is the main subject of this study. The statistical population of this study includes all experts and professionals active in the field of psychiatry and law who specialize in the topics related to sexual violence of pedophiles, and 235 of them were randomly selected. The research tool is a researcher-made questionnaire based on 47 questions, and the desired model is fitted based on PLS. The obtained results indicate that factors such as personality disorder, depression, suicide, alcohol and drug use, family problems, mental-psychological problems, and medical history are among the common characteristics of pedophiles. Educational and control measures, educational factors and criminal punishment are the proposed solutions for prevention and economic, social and cultural factors are among the underlying factors in becoming a pedophile.On some anisotropic elliptic problem with measure data

The construction of the proof of our theorem is done by using Minty's Lemma in its modified version.The effect of integrated green management program and internal and external organizational factors on green banking and social and security factors
https://ijnaa.semnan.ac.ir/article_8874.html
Today, one of the big challenges of banks is the greening of actions and, most importantly, maintaining social and security factors as one of their important tasks, which can increase public trust and reduce people's concern about the impact of their activities on the environment, which itself It requires extensive research that some researchers have done more or less. However, less research has considered these important issues from the perspective of the effects of the integrated green management program and internal and external organizational factors. Based on this, the current study investigates the impact of integrated green management programs and internal and external organizational factors on green banking and social and security factors. The current research method is a practical and descriptive survey. The statistical population, including 400 experts on the banking system, were selected as a sample using a stratified random method. The data collection tool was a questionnaire. The results of structural equation modelling using Smart PLS software showed that the integrated green management program significantly affects internal organizational factors. Also, the integrated green management program significantly impacts external organizations. In addition, internal organizational factors have a significant impact on social and security green banking. On the other hand, extra-organizational factors have a significant effect on green banking, as well as social and security factors.Jensen’s inequality for (p-q)-convex functions and related results

https://ijnaa.semnan.ac.ir/article_8557.html
In this article, the problem of pricing discrete double barrier options which only monitored at specific times is investigated. According to the Black-Scholes framework, the option price would be obtained from recursively solving the Black-Sholes partial differential equations on the monitoring intervals. In this way, the sine-cosine wavelet approach is applied in approximating the yielded analytical expression. Finally, an operational matrix form is derived which is highly comparable with other methods. According to the method of the present paper, the computational time is nearly fixed against increases in the number of monitoring dates.Biometrics based on deep learning: A survey

https://ijnaa.semnan.ac.ir/article_8773.html
Vague sets (VSs) being the most advanced form of fuzzy sets has more capacity to analyze the network state more intelligently. It is proven that VS is more useful to solve many real life problems having uncertainties. Fuzzy graphs (FGs) are efficient mathematical models for analyzing many problems of daily life. One of the most widely used types of FG is vague incidence graph (VIG). VIGs play an important role in various fields such as computer science, pcychology, medicine, and political sciences and are used to find effective people in an organization or social institution. They can be used to describe the problems which cannot be handled through FGs and VGs. So, in this paper, specific ideas analogous to vague cut vertices and vague bridges in VGs, &nbsp;vague incidence cut-vertices, and vague incidence bridges are explored. The notion of vague incidence &nbsp;gain and vague incidence less for vague incidence paths and pairs of vertices is also initiated.Fixed point theorems for weakly contractive mapping on generalized asymmetric metric spaces

https://ijnaa.semnan.ac.ir/article_8781.html
In this paper, a new class of nonconvex optimization problem is considered, namely &nbsp;$(h,\varphi)$-$(b,F,\rho)$-convexity is defined for $(h,\varphi)$-differentiable mathematical programming problem. The sufficiency of the so-called Karush-Kuhn-Tucker optimality conditions are established for the considered $(h,\varphi)$-differentiable mathematical programming problem under (generalized) $(h,\varphi)$-$(b,F,\rho)$-convexity hypotheses. Further, the so-called &nbsp;Mond-Weir $(h,\varphi)$-dual problem is defined for the considered $(h,\varphi)$-differentiable mathematical programming problem and several duality theorems in the sense of Mond-Weir are derived under appropriate (generalized) $(h,\varphi)$-$(b,F,\rho)$-convex assumptions.Fixed point theorems for $\theta$-$\Omega$-contraction on $ (\alpha,\eta )$-$b$-rectangular metric spaces

Some inequalities involving $(k, \psi)$-Hilfer fractional integrals are also to be proved.Pairwise compactness in bi-isotonic spaces
https://ijnaa.semnan.ac.ir/article_8787.html
In this article, we have introduced the notion of pairwise compactness in bi-isotonic spaces via finite intersection property and pairwise open cover. Moreover, we have given pairwise compactness of bi-isotonic subspaces with both reduced closure and interior functions. We have characterized pairwise compactness by the neighborhood concept; however, the axioms of bi-isotonic spaces are insufficient to prove the theorem, and we have studied this in bi-closure spaces. For similar reasons, occasionally, bi-closure spaces have been considered with additional explanations, even if some concepts related to compactness have been naturally extended to bi-isotonic spaces. Additionally, interesting results have been obtained considering the pairwise Hausdorffness and compactness relationship. It has also been observed that resembling cross-relationships exist for closed subsets of pairwise compact spaces. Finally, it has been observed that the pairwise compactness of bi-closure spaces is preserved under bi-continuity.Predicting the expected returns of cryptocurrencies using CAPM and D-CAPM approaches
https://ijnaa.semnan.ac.ir/article_8821.html
In the present study, the expected returns of cryptocurrencies were compared capital asset pricing model (CAPM) and downside capital asset pricing model (D-CAPM) approaches. For this purpose, fifty cryptocurrencies were studied as representative of risky assets in a five-year period from 2018 to 2022 with daily frequency. First, the panel was investigated using Levin-Lin-Chu, Im-Pesaran, and Shin and Dickey-Fuller's tests. Then, using paired t-statistics, the difference between the return estimates of the two models was investigated. Finally, using R2 and the generalized linear test model, the better model was selected to justify the changes in asset returns in these cryptocurrencies and portfolios. Based on the results, in almost 90% of the analyzed portfolios, the D-CAPM model was better than the CAPM model and had more justification power than the old CAPM model. In less than 1% of the models, the degree of justification and the appropriateness of the models were the same.New analytical soliton solutions to the stochastic fractional long–short wave interaction system with multiplicative noise

https://ijnaa.semnan.ac.ir/article_8896.html
In this paper, we extend the $q$-derivative operator, which plays an essential role in quantum calculus. Indeed, by using the Hadamard product and generalized Koebe function we define the following $(\alpha,\beta,\gamma)$-derivative operator\begin{equation*}&nbsp; &nbsp; {\rm d}_{\alpha,\beta,\gamma} f(z)=\frac{1}{z}\left\{f(z)*\mathfrak{L}_{\alpha,\beta,\gamma}(z)\right\},\end{equation*}where\begin{equation*}&nbsp; &nbsp; \mathfrak{L}_{\alpha,\beta,\gamma}(z)=\frac{2(1-\gamma)z}{(1-\alpha z)(1-\beta z)},\end{equation*}and $\alpha\in[-1,1]$, $\beta\in[-1,1]$, $\alpha\beta\neq \pm1$ and $\gamma\in[0,1)$. Then by subordination relation, the operator ${\rm d}_{\alpha,\beta,\gamma} f(z)$, and a special function $\phi_\delta(z)=1+\delta z/\exp(\delta z)$ ($0&lt;\delta\leq1$), we define a new particular Ma-Minda class. We investigate some properties of this class, such as, radius problem and coefficient estimate.A new generalization of the $l_p$ spaces

https://ijnaa.semnan.ac.ir/article_8909.html
This research was conducted to present a model of information technology acceptance in internal auditing using the fuzzy Delphi approach. In this study, a sample of 15 financial managers, internal auditors from companies, and audit experts was utilized, employing a non-random and judgmental sampling method. The fuzzy Delphi method was employed for screening the factors. Accordingly, the factors were initially identified as 38 factors for the experts, and through the fuzzy Delphi approach, they were reduced to 12 factors in three stages. Subsequently, a structural interpretive model was used to determine the significance and prerequisites of the validated factors. Ultimately, a four-level model of factors influencing the acceptance of information technology in internal auditing was identified. Considering that each category of factors consisted of a set of variables that were examined, the analysis of the data determined their order. The variables for the first to fourth levels are as follows: Level 1: Specialized training, management awareness, management support and encouragement, auditor's trust in technology adoption, and audit report quality. Level 2: Specialized training, management awareness, management support and encouragement, and audit report quality. Level 3: Specialized training for auditors, management support and encouragement. Level 4: Specialized training for auditors. Finally, based on the findings of the research, recommendations were provided for management and employees, as well as suggestions for other researchers.
