Also, based on the standardized root mean square residual index (SRMR), which has recently become more preferred, the acceptable fit of this model has been confirmed. The findings showed that firstly, there is a significant correlation between the constructs of the health action process approach model and micro-savings behavior among the study participants. Secondly, the constructs of action self-efficacy, outcome expectations and risk awareness were able to predict 62% of the variance of behavioral intention, and also, the intention with the mediation of planning together with maintenance self-efficacy and recovery self-efficacy, 59% of the behavior variance. They predicted small savings. Conclusion: In this study, we found that intention, action self-efficacy, planning and self-efficacy play a role as the most important determining factors in the adherence to savings in the target community. It was found that HAPA is useful in determining the predictors of adherence to savings among people. It is promising to design intervention programs to improve the level of adherence to savings by considering these factors. Macro policymakers and market leaders, especially financial businesses, should focus on the self-efficacy and planning of people in designing such interventions so that they can change the financial behavior of customers for the benefit of savings for themselves and their customers. https://ijnaa.semnan.ac.ir/article_8538_065578d5dbd2ba982e3d70bad2c66c4f.pdf

The presented control is comprised of two parts, an adaptive fuzzy control part that performs the main control action and a quantum-fuzzy control part that is implemented when the existence and uniqueness of the solution are not established. Thereby, the adjusted laws of the control parameters and the quantum-fuzzy rules are designed via the Lyapunov-based technique such that the stability of the system is guaranteed. One theorem for facilitating the Fuzzy controller design algorithm is presented and proved. The proposed control method enhances the applicability of the quantum stochastic control theory for many practical control problems such as portfolio management. Therefore, theoretical results are illustrated by simulating the pairs trading problem. According to simulation results, the performance of the pairs trading strategy is improved as an increasing return portfolio that is controlled by the proposed method. https://ijnaa.semnan.ac.ir/article_8481_5fa31574b6c2cf7b0ab4b18017da239b.pdf

These layers may easily be dissolved due to contact with groundwater flow, causing some cavities in the soil and settlement of the structure which in severe conditions may highly damage or ultimately lead to failure of the structure. Since nearly all studies carried out on soluble layers so far, have been concentrated on different factors influencing the solubility of the layers under free field conditions, the effect of overburden which roots from the weight of the structure may have an important and influential role in the phenomenon in many engineering projects. Therefore, to fill the gap in past studies on this topic, investigating the effect of overburden on the rate and types of solubility of the susceptible layers is of great necessity and importance. In the present study, the effect of overburden pressures on solubility and erosion of soluble layers has been assessed and investigated. The circulation tests on cubical gypsum samples taken from a mine in Semnan province, west of Tehran, have been carried out. At the same time, they were subjected to different overburden pressures in a new apparatus developed for this study. Cylindrical holes of different initial diameters from 6.5 to 14.75 mm. were cut in the center of samples for the flow passing through and the final diameters of the holes were measured after the electrical conductivity of the flow getting stable during the circulation test. Different flow rates, different overburden pressures and different diameters of holes have been examined and the electrical conductivity was monitored during circulation continuously. Based on the testing results, for relatively large initial hole diameters (eg: 9 & 12.5 mm.), the electrical conductivity decreases as the overburden increases. For greater hole diameters the rate of decreasing the electrical conductivity decreases and nearly becomes constant by increasing the overburden. Nevertheless, the variations of electrical conductivity get an unspecific trend by increasing the initial hole diameter and the overburden pressure. https://ijnaa.semnan.ac.ir/article_8523_6d5a6e20fab6caf98d478bacd7d5a619.pdf

Correlation between variables shows that changing the value of one variable leads to changing another variable in a certain direction. It is also possible to use the value of one variable to predict the value of another. In statistics, the correlation coefficient measures the direction and strength of the tendency to change. In machine learning, the correlation coefficient is known as a measure of classification quality. In fact, as a starting step for classification, the correlation between different samples should be estimated using a specific method. There are various methods to estimate the correlation of different data types, which have disadvantages such as low accuracy or high computational time. One of the methods that can overcome these problems, due to its high capability in modeling correlation between samples is graphical modeling. In this research, a new covariance model based on graph theory and graph neural network for estimating the correlation between samples is presented. The results show the improvement of the proposed model in accuracy, sensitivity, precision, F-Micro, F-Macro and statistical tests compared to Pearson and cosine methods. https://ijnaa.semnan.ac.ir/article_8438_6a7502f0cb62d3f941f9b589efad571d.pdf

Ayatollahi Department of Electrical Engineering, Iran University of Science and Technology, Narmak, Tehran 16846-13114, Iran Journal Article 2023 12 10 A common technique for navigation and positioning applications is the Global Positioning System (GPS)/Inertial Navigation System (INS) integration, which combines the strengths of GPS and INS to offer accurate and reliable information. As a standalone system, the performance of the INS deteriorates as time is passed. Kalman Filter (KF) is used for GPS/INS integration, and its performance is excellent for simple data. However, in a complex and natural set environment, its performance degrades when the system performs relatively long; therefore, resolving the long-time problem for the GPS/INS system is challenging. The novelty of this paper is GPS/INS integration with the Faded Kalman Filter (FKF). In the FKF, the measurement updates are weighted differently to adapt to changes in the system. This approach allows the filter to adapt to changes or uncertainties in the system dynamics. GPS/INS integration performance is significantly improved using this algorithm rather than a simple KF. An average of 45% reduces the positioning errors compared to traditional KF. https://ijnaa.semnan.ac.ir/article_8576_478e17ebbea22267affc378afd24ccb6.pdf

These variables include; The independence of the board of directors, the size of the board of directors, the size of the audit committee, the independence of the audit committee, the financial expertise of the audit committee, the number of meetings of the audit committee, and the duality of the CEO. To achieve the goal of the above research, the approach of Lipsey and Wilson (2001) was used and also, and the implementation of Cochran and Egeer's Q tests including 9 domestic articles and 19 foreign studies during the years 2010 to 2023 was investigated. The results showed that there is no significant relationship between the size of the board of directors and the size of the audit committee, the independence of the audit committee, the number of meetings of the audit committee, and the duality of the CEO with the ARL. However, there is a significant negative relationship between the board of director's independence and the audit committee's financial expertise. The activity of expert auditors in the audit committee can speed up the audit process of companies and ensure that financial statements reach users on time. In addition, shareholders can take the main step toward timely financial statements by electing an independent board of directors. https://ijnaa.semnan.ac.ir/article_8595_2215d58a4d225926b2738cafcef995cc.pdf

In other words, this paper seeks to answer “whether financial constraints can lead to the decline of stock price crash risk or not”. The study method is descriptive correlation based on published information from listed firms on the Tehran Stock Exchange from 2012 to 2019, with a selected sample that includes 119 firms (952 observations). The method used for hypothesis testing is linear regression using the integrated data. The obtained results from hypothesis testing show a positive and significant relationship between financial constraints and stock price crash risk, which means the more financial constraints in Iranian business firms, the higher the risk of stock price crash. Since this paper is carried out in an emergent financial market, like Iran, that is highly competitive with severe economic sanctions and high inflation, it can provide helpful information in this area for the readers and contribute to the development of science and knowledge. https://ijnaa.semnan.ac.ir/article_8597_127345403a2719d54b0a4ff916945c50.pdf

One of the necessities of every business is to know the preferences and understand the customer experience. Understanding the customer experience is often done through questionnaires and surveys, which has limitations that have caused the answers to be inaccurate, as well as the orientation of the questions based on the researcher's mind. With the emergence of social networks, users present their opinions regarding the experience they had with products and services. This causes the production of valuable big data. Online reviews are one such source of data, created from customers' self-reports of their experiences. Considering that the hotel industry in Iran needs to develop and increase the share of the international market, the online reviews of five-star hotels in Iran were analyzed on the world-renowned platform. In this study, the approach of frequency analysis and semantic network analysis was used to extract topics in the perceived experience of customers, then using factor analysis, hidden factors were discovered. Finally, to model the relationship between the factors and its effect on satisfaction, a linear regression model was performed. This research obtained valuable findings from the opinions of customers that in addition to the major role of staff behavior, room facilities in satisfaction, the different role of food service in different meals, the effect of the beauty of the city and the purpose of the trip can be mentioned. https://ijnaa.semnan.ac.ir/article_9404_3cb34983b19bb8b342969c256f1b49c6.pdf

Ardabil province is part of the Western Alborz tectonic unit-Azerbaijan. Azerbaijan region is considered one of the~tectonically active regions. The main activity of this region is the result of the movement of the Arabian block, which affects the north-western corner of Iran, the Caucasus Mountains and eastern Turkey by 3 cm per year. This research was conducted to determine the seismic hazard of Ardabil province using a probabilistic method. After determining the characteristics of seismic sources, the seismicity or time distribution of the earthquake event was investigated and a regression relationship was used to determine the seismicity of each seismic zone. Determining the ground motion resulting from an earthquake event of any possible magnitude in the site, which may occur at any possible point of each source area, was done using attenuation relationships. Finally, the uncertainty in the location of the earthquake and its magnitude were combined in determining the ground motion parameters to determine the probability in which the ground motion parameter occurs in a certain period. The calculations were performed using the R-CRISIS software utilizing the Gutenberg-Richter seismicity model. This study revealed that the north and southwest faults of Ardabil province are the most active source in terms of seismic hazard. The maximum value of the magnitude of the earthquake for Ardabil province for the return period of 475 years was obtained at 8.2-8.8. https://ijnaa.semnan.ac.ir/article_8774_a451ff088a46712e860c4819f4223e95.pdf

In the current situation, the appearance of the auditor's choice is based on legal criteria, and this choice is often made by the managers who are responsible for the company's performance. Although the commercial law leaves the selection of the auditor to the general assembly and the charter of the audit committee of the Securities and Exchange Organization entrusts the task of examining and recommending the auditor to the audit committee, but the selection is made by the board of directors, the managing director, the director of the affairs of assemblies and companies and sometimes it is done in lower organizational levels, such as financial managers, which brings many problems. Therefore, our goal is to provide the optimal model for the selection of audit institutions by an independent institution and authority, with an emphasis on independence. For this purpose, we used the fuzzy Delphi method to collect the opinions of experts in this regard. The selection of the audit institute and the assignment of work to the audit institutes by an independent and reference body will increase the independence of the audit institutes. The results of this study show that we can increase and maintain the independence of the audit institutes and not the auditor in this way. Choosing audit institutions with this approach can have many positive effects, including proper distribution of work between audit institutions, increasing the quality of audit institutions' reports, increasing investors' trust and as a result increasing investment, preparing a reliable and independent report without the influence of the manager and the company, for the institutions to carry the executive and supervision of the country. https://ijnaa.semnan.ac.ir/article_8685_6efd39ac37fddb012888bad7dd4d819e.pdf

It is an approximation that, ironically, the literal meaning of the word "argument" also refers to the clarification of something by the same thing (function input or armagon). Now the basic question is that while the educated mind of man has considered logic as equivalent to the mechanism of definite perceptions and accurate results for more than a thousand years, how can we talk about the invention of a logical method that is based on uncertainty? This question is doubly important from the aspect that our approximate arguments in the context of our lived life are more than our exact, definite and unambiguous arguments, that is, the same arguments that classical logic, whether in its old or new language, He leaves it aside and does not pay attention to them, and of course he is forced to do this because he does not have the tools to analyze these arguments. This is where we unknowingly remind ourselves of Bacon's angry regret, who considers Aristotelian logic to be a fantasy that causes waste and diversion of great talents over many centuries, a continuous and constant effort without helping a person to improve the quality of his life; A bunch of delusional nonsense, the result of which, perhaps in the most optimistic state, is Scott's adversary and the victory of futility in verbal disputes, of course, if we do not say only pointless boasting and scrutiny based on rhetoric, the fruit of which is the explanation of rational axioms. If Mr. Bacon knew about fuzzy logic, he would have corrected his view of logic, and to be more precise, he would have separated Aristotle from logic, not logic from science. One of the most important advantages of fuzzy logic is that it can introduce a way to enter the knowledge and experiences of experts into intelligent systems that are based on sensitive and practical decisions and choices and develop the previous absolute correct and incorrect logic. The basis of the analysis in the present research is to examine the components of two types of logic, i.e. classical logic and fuzzy logic, and clarify the understanding of the logical concepts and philosophical foundations of classical logic, as well as comparing it with the concepts of fuzzy logic. The research results indicate: these two types of logic have fundamental differences from an epistemological point of view; Aristotle's epistemological foundation is based on the certainty-oriented duality of "either this/or that", while the fuzzy epistemological foundation is based on a multi-valued system and that both logics are a contradictory understanding of what the mind and the external world are and the connection between They both give hands. https://ijnaa.semnan.ac.ir/article_8836_4cd4db2344517ba2f1fa587bfd1a07d5.pdf

We proved some convergence results for such classes of mappings using the properties of $G$-metric space and found the fixed point results for such contractive mappings. To elaborate on the results we provided some examples, which show that our results hold in the setting of $G-$metric spaces. https://ijnaa.semnan.ac.ir/article_8837_06af0c198a905b917f699f1df7f89c36.pdf
