In command and control, it is necessary to provide clean data to the system for better decision-making in the battle scene. In this regard, artificial aperture radar is an imaging radar with high resolution, which needs to improve the quality and classification of these images to recognize the details of the scene. The presence of speckle noise is the most important factor in image quality degradation, and it is necessary to reduce the effect of speckle noise in the pre-processing stage. Also, one of the important methods in interpreting SAR radar images is the classification of images, which is very useful in examining the changes in ground targets, because the observation and monitoring of targets in command and control is considered a good tool. Determining a classification method with appropriate accuracy for SAR radar images with high spatial resolution is a goal in this article, as the old algorithms in this field such as Kmeans, Perceptron, SVM, and MLP have poor detection power and inappropriate speed. As a result, in this article, the aim is to present a powerful algorithm for optimizing the classification of SAR radar ground targets with the help of the proposed method of combining convolutional network and genetic algorithm, which can be obtained through airplanes, spacecraft or satellites to observe ground targets. has been In this article, in the pre-processing stage, after reducing the effect of speckle noise on SAR radar images with the help of the Lee filter, the optimization of the classification of SAR radar ground targets with the proposed method has been obtained, and acceptable results have been obtained. The proposed network has performed 99.33% better than other methods in terms of classification accuracy of denoised MSTAR images.

This research is applied in terms of purpose and qualitative in terms of research method and its main purpose is to explain the model of command and control human capital training with a research-oriented approach. The present research was carried out by thematic analysis method with a summarizing approach and using library studies and semi-structured in-depth (comprehensive) interviews with experts and led to the design of the model. The interview was conducted in a semi-structured individual and focal way (in two stages). The statistical population of this research includes the experts of A military education and training center, who are familiar with the basics of command and control and research-oriented trainings, using the purposeful selective sampling method, initially 12 people as a sample of experts. The beginning of the research was determined and then the necessary data was collected; During the interview, new experts were identified, and a total of 17 people were interviewed and theoretical saturation was achieved. To determine validity, triangulation (triangulation) of data sources was used, i.e. from the three sources of professors/faculty members, experts and assistants. The purpose of triangulation is to overcome the inherent biases that result from using a source, a method, an observer or a theory in studies. To determine the reliability, the agreement between two coders (evaluator) or intra-subject agreement was used, and the reliability rate was calculated using the formula, 79%, which is higher than 60%; So the reliability of coding was confirmed. Based on the summation of the opinions of academic experts and after implementing the concepts obtained from the library studies and the text of the interviews, thematic analysis was carried out, and in the first stage, 80 basic themes were counted; Then, in the next stage, by merging similar themes and removing duplicate themes, the basic themes reached the number of 36 themes, which were classified into 4 organizing themes. The results of this research showed that the command and control human capital training model with a research-oriented approach is based on 4 organizing themes, including educational factors with 10, support factors with 5, administrative and executive factors with 14 and cultural factors with 7 themes. The foundation is established.

The results of the analysis of the recent wars show the fact that all the military theorists refer to asymmetry as the main and most important characteristic of the environment of future wars and believe that in such environment, the attacking countries in the first wave of attack, by using a large amount of modern and accurate weapons and facilities, aim to destroy the country's defense equipment as much as possible so that by gaining and maintaining air superiority, other attacking forces can in an atmosphere free from threats, Pursue your goals and achieve victory. On the other hand, due to the superior geopolitical, geostrategic, geoeconomic, etc. position c. A. Iran has witnessed continuous threats against J. A. We are Iran and after the victory of the Iranian Islamic Revolution, this country has always been at the forefront of threats. In such a situation, it is necessary to pay with a codified and specific method to improve the capability of successful defense against unequal enemies. The present type of research is applied-developmental and its approach is mixed with descriptive-analytical method. The data was collected by two library and field methods (interviews and questionnaires), and qualitative information obtained by content analysis method and quantitative information obtained by using quantitative data analysis software were analyzed. have taken The validity of the questionnaire was calculated through content validity and reliability with Cronbach's alpha. Finally, from the findings of the research, the strategic model with two dimensions of non-war time (including 11 components) and war time (including 8 components) has been calculated and presented.

Today , economic centers such as refineries, political centers such as parliament, government, judiciary and military centers such as barracks can be attacked by spy or suicide Mini-drones. Various systems and methods have been proposed to detect and identify this threat. Since this issue is a competition between two groups of defenders and attackers, several factors are effective in the decision-making of these two groups, their operational approach and the optimal selection of equipment. In this research, by using the game theory based on the graph model, we have been able to, in the first step, by considering the two parameters of cost and budget in equipping the electronic warfare , as well as the operational range of the systems in two independent scenarios, considering the equipment of the parties and the preferences of the actors. Predict the battle scene and the equilibrium situations based on game theory.In the second step, by combining these two components and simultaneously applying the influence of the decision parameters in a cost function, we predict the final state of detection and identification of the Mini drone and, taking into account the real conditions, we model the correct decision-making process for the commanders of the battlefield of electronic warfare. The results show that the simultaneous effect of two parameters, cost and operating range, have completely opposite results with one-dimensional decisions. Also, the cost function can be effective in changing the results

Today, mobile phones have become a global phenomenon and have created a virtual community with hundreds of millions of users. Facilities such as the ability to make voice and video calls, send text and multimedia messages, use different programs, etc., have caused the desire to use these devices more than before, on the other hand, crimes related to this field have also increased, therefore, in order to be able to use digital evidence extracted from mobile phones to discover the traces of crimes, requirements are raised that cause the standardization of the evidence extraction procedure. Presenting strategies in the mobile digital evidence requires knowing as much as possible the features related to the citation of the mobile digital evidence and then prioritizing them. The purpose of this research is to provide a model for these requirements which able to identify, explain and prioritize these requirements in the first place and then provide solutions for these requirements. In order to achieve these requirements, interviews were conducted with a number of experts of scientific and executive centers with at least bachelor's education and several years of activity related to this field. The research method is quantitative and qualitative way, and the data of this research is from studies of previous works, the work experience of the authors, and also through in-depth interviews with 12 of the main experts in the qualitative stage and 20 of the intermediate experts in the quantitative stage. By collecting information to identify the citation requirements of extractive evidence, was addressed the main question of the research, which was to provide a conceptual model for these requirements. Indicators related to the examination of malware, phone access permissions, program-based challenges,  hardware problems, how to extract evidence, content of evidence extraction and training expert which present with 66 components, that the most important requirement is phone access permissions with 88.60%. Finally according to the current situation of the responsible organizations in the field of mobile digital forensic to achieve requirements can be considered some suggestions in paper.

Certainly, crisis management is the main factor of strategic management of the organization. So that before pursuing any lofty goals, crisis management is necessary to ensure the stability and continuous success of an organization. Basically, for organizations that are exposed to crisis, more preparedness against crisis is very important. Effective crisis management requires a systematic and orderly approach that must be based on vigilance, managerial sensitivity and a good understanding of the importance of detailed planning and organizational preparation. The purpose of this research is to design the model of organizational culture in crisis management with a mixed approach, in other words, this research is the answer to the question, what is the model of organizational culture in crisis management? is.
 This research was compiled with a practical approach and a survey method in a mixed (quantitative, qualitative) way. In this research, after collecting the required information, the data obtained from the review of books and scientific publications in the field of the research subject, firstly classified and processed and finally judged by the researcher.
The statistical population of this research includes managers who are familiar with organizational culture and crisis management in particular (managers working in human resources, inspection, crisis management, occupational safety and health units). The sample size was determined by random sampling and 150 people. The results of the research show that the adhocracy culture and the family culture, respectively, have the greatest impact on crisis management in the industry.
