Robotization plays a pivotal role in addressing the hazardous and labor-intensive nature of demining operations. The purpose of this paper is to review prominent computer vision tech-niques, particularly object detection, and analyze their applications in the specialized domain of explosive ordnance detection. An extensive review of the literature was conducted to explore the utilization of computer vision in the field of explosive ordnance detection. The study in-volved a comparative analysis of diverse imaging sensors employed for data capture. Special at-tention was given to reviewing sources that elaborate on different methods for detecting objects within the field of computer vision. Various approaches to object detection were thoroughly examined and compared. The research extensively examined the metrics and datasets used to evaluate different approaches for object detection. Possibilities of applying computer vision methods to detect explosive ordnance under the limitations of mobile platforms were studied. Directions of future research are formulated.","PeriodicalId":474184,"journal":{"name":"Èlektronnoe modelirovanie","volume":"73 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140459305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to im-prove the decision-making process, a number of probabilistic models are considered, which are based on the calculation of subjective probability estimates regarding the occurrence of danger-ous events and forecasting the corresponding risks. Factors of various nature are considered during modeling: external influences, concentrations of harmful substances, greenhouse gas emissions, indicators of the state of safety of man-made productions, efficiency of equipment, accounting of violations, and other indicators. Also, the knowledge system provides for calcu-lating the risks of dangerous events, the probability of which increases under the interaction of two or a number of hazardous factors. On the basis of the conducted research, an algorithm for building and the structure of a probabilistic model of knowledge focused on software implementation in the decision-making support system for managing the safety of man-made enterprises that pose threats to the popula-tion and the natural environment has been developed.","PeriodicalId":474184,"journal":{"name":"Èlektronnoe modelirovanie","volume":"65 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140459081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A primary broadcast system for multimedia video streaming applications that broad¬casts data to primary users and an auxiliary cooperative relay secondary cognitive ra-dio system are considered. The secondary cooperative overlay system can use multiple error control coding methods for point-to-point data retransmission, such as channel coding, network coding, and combi¬ned coding methods to improve system performance under variable link con-ditions. A new technique of adaptive coding of AC2NC combined channel network for data re-transmission is proposed. The new AC2NC first analyzes the channel feedback information and then selects the best retransmission coding technique based on the target bandwidth or trans-mission time optimization. This is instead of using a single static channel or a network coding technique with dynamic channel conditions. The proposed AC2NC improves system through-put, reduces retransmission time, and provides more spectrum access opportunities for the sec-ondary sys¬tem's own data transmissions. AC2NC's relative throughput and time saving capabil-ities for cognitive radio users have been shown to exceed ninety percent, under certain channel conditions, compared to some static coding methods.","PeriodicalId":474184,"journal":{"name":"Èlektronnoe modelirovanie","volume":"54 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140459395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been proven that the development of computer network technologies is gradually accelerating, as today vulnerability is considered a potential threat to information security. The main prob-lems of computer information leakage and computer software encryption technology to prevent computer information leakage are analyzed. Classification of the information leak has been car-ried out. The consequences of information leakage, which have an impact on the economic ben-efits of enterprises or individuals, have been studied. Data leakage prevention methods have been proposed and are currently relevant, including technical tools and product solutions such as traditional DSM (Data Encryption Management) and DSA (Data Security Isolation), as well as DLP (Data Leak Prevention) based. The protection technology to contain the leakage of computer information was analyzed. It is justified that due to the fact that electrostatic shielding is used to prevent electrostatic communication interference, it is advisable to use grounding conductors. It is determined that electromagnetic shielding uses the principle of reflection and absorption of electromagnetic waves on the surface of the conductor and inside the conductor to protect against high voltage interference.","PeriodicalId":474184,"journal":{"name":"Èlektronnoe modelirovanie","volume":"105 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138982935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is proposed to use a tuple of M-η pairwise distinct elements of the set of integers of the segment [0; M 1] as a syncword. The elements of this set are encoded with a fixed-length binary code and the minimum binary Hamming distance between the syncword and all its circular shifts is the maximum. The paper established that the maximum value of the minimum Hamming distance for tuples of 15 pairwise distinct elements of the set of integers for M = 16 is equal to 30. A comparative assessment of the frame synchronization effectiveness was performed based on tuples of 15 elements, as well as on permutations of length 16 and 8. A computer simulation model of the frame synchronization system in a binary symmetric communication channel was built. Synchronization indicators were determined with parameters calculated for bit error probability 0,4 and 0,495, as well as requirements for a min-imum probability of correct synchronization of 0,9997 and a maximum probability of false synchronization of 3E-4. The effectiveness of using tuples of pairwise distinct elements in frame synchronization systems has been confirmed. The efficiency indicator depends on com-munication channel bit error probability.","PeriodicalId":474184,"journal":{"name":"Èlektronnoe modelirovanie","volume":"461 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138983040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
