In technical systems, there is a common situation when transformation input-output is described by the integral equation of convolution type. This situation accurses if the object signal is recovered by the results of remote measurements. For example, in spectrometric tasks, for an image deblurring, etc. Matrices of the discrete representation for the output signal and the kernel of convolution are known. We need to find a matrix of the discrete representation of a signal of the object. The well known approach for solving this problem includes the next steps. First, the kernel matrix has to be represented as the Kroneker product. Second, the input-output transformation has to be presented with the usage of Kroneker product matrices. Third, the matrix of the discrete representation of the object has to be found. The object signal matrix estimation obtained with the help of pseudo inverting of Kroneker decomposition matrices is unstable. The instability of the object signal estimation in the case of usage of Kroneker decomposition matrices is caused by their discrete ill posed matrix properties (condition number is big and the series of the singular numbers smoothly decrease to zero). To find solutions of discrete ill-posed problems we developed methods based on the random projection and the random projection with an averaging by the random matrices. These methods provide a stable solutions with a small computational complexity. We consider the problem of object signals recovering in the systems where an input-output transformation is described by the integral equation of a convolution. To find a solution for these problems we need to build a generalization for two-dimensional signals case of the random projection method. Purpose. To develop a stable method of the recovery of object signal for the case in which an input-output transformation is described by the integral equation of a convolution. Results and conclusions. We developed the method of a stable recovery of object signal for the case in which an input-output transformation is described by the integral equation of a convolution. The stable estimation of the object signal is provided by Kroneker decomposition of the kernel matrix of convolution, computation of random projections for Kroneker factorization matrices, and a selection of the optimal dimension of a projector matrix. The method is illustrated by its application in technical problems.","PeriodicalId":33554,"journal":{"name":"Control Systems and Computers","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44366374","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}

The development of effective digital medicine tools is an intensive and complex process that requires the interdisciplinary efforts of a wide range of experts, from scientists and engineers to ethics experts and lawyers. Digital medicine products have great potential for improving medical measurement, diagnosis and treatment. One of the main challenges for the healthcare sector is to address the issue of fast, convenient and secure exchange of information about patients’ health. Service-oriented architectures of such products may accomplish many of the challenges facing healthcare systems. The purpose of the paper is to develop an information and software module ExchangeDMD to ensure the accumulation, storage and exchange of diagnostic medical data in accordance with modern medical information standards to maintain the interoperability function as one of the leading principles of digital medicine. Results. A special adaptive architecture of digital medicine infrastructure has been developed, which enables an integrated solution of data exchange between participants of providing medical services, which is carried out with the help of web services. The specifics of different types of medical information are analyzed and taken into account in accordance with the access regime for its processing. The module structure has been developed and implemented in software, which has three main levels: central virtual storage (virtual data center to implement certain functions), remote administration segment (technical support and administration network) and user segment (mobile devices and user-patient applications). Conclusions. The ExchangeDMD information and software module is designed to ensure the accumulation of patient data, integration between the various units within the system, as well as to ensure the management of this data by health care personnel. The ExchangeDMD module is built using the international standard HL7 CDA, which enables formalizing electronic medical records using RIM (information model links) to attract the necessary directories and classifiers when creating medical records and documents.","PeriodicalId":33554,"journal":{"name":"Control Systems and Computers","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43802648","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}

At the current level of development of research in the field of artificial intelligence, it is defined as a set of technological solutions that allow simulating cognitive functions, obtaining results comparable to the results of human intellectual activity. In this regard, the problem arises of creating a technology that imitates the cognitive functions of analyzing the state of objects when the conditions of their functioning change. Analysis of the status of objects in the different problems of environmental, technical, social, political and other nature is carried out most often on information models. The peculiarity of their solution lies in the fact that it is necessary, as a rule, to restore indefinite, sometimes not amenable to quantitative analysis, dependencies and patterns. Since full-scale experiments in these subject areas are often impossible, and sometimes very expensive and even dangerous, the only research method in this case is a thought experiment using the method of experimental perturbations of the state of an object. Purpose. The purpose of the article is to create a method of cognitive modelling based on a thought experiment for the problem of assessing the state of an object from incomplete and fuzzy data. Methods. To implement the method of cognitive modelling based on a thought experiment, the method of a mental complete factor experiment (MСFE) is applied using the method of experimental perturbations. Results. To implement the method of cognitive modelling based on a mental experiment, a procedure has been created that evaluates the state (behaviour) of an object in a present or anticipated future situation based on the method of a mental complete factor experiment (MСFE) using the method of experimental perturbations. The developed procedure makes it possible to obtain solutions to the problem of predicting the state of a certain object in the future using incomplete and fuzzy data and using an expert “built in” to evaluate the forecasting results. Conclusion. The results of the research presented in this article, which are conceptual in nature, show the possibility of creating elements of technology that imitate the cognitive functions of analyzing the state of objects when changing the conditions of their functioning using a thought experiment. The developed method can be used to solve the problems of assessing the state of various objects when creating intelligent information analysis systems in order to obtain new knowledge about the object.","PeriodicalId":33554,"journal":{"name":"Control Systems and Computers","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48376694","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}

Hierarchical control in complex multilevel systems has been studied since the period of classical cybernetics. At that time, basic definitions and concepts were introduced. It is time to start remembering those achievements because those decisions can already be implemented. However, the situation is constantly changing (evolving), so those tasks are perceived differently today. And the question arises as to how these old developments will progress, whether they will be used? Purpose. The purpose of this work is an attempt to predict the development of hierarchical multilevel control systems in the future and how it depends on the latest technologies that determine their software-hardware complex (SHC). Result. The analysis of the essence of the multilevel hierarchical management system, its features and additional requirements for the software-hardware complex, the current state of hierarchical management systems, the impact of advances in IT technologies and theories on the features of hierarchical management are carried out. The current state is studied on the example of NATO hierarchical systems. Based on the forecasts of the development trend of IT technologies, the forecast of trends in changes in hierarchical multilevel control systems is proposed. Conclusions. As a result of the analysis of the essence of hierarchical multi-level management systems, the current state, and forecast of the development of IT technologies, the authors made the following conclusions: – the hierarchical structure of a complex multi-level system will be in demand in the near future; – Hierarchical systems will consist of standard components with elements of artificial intelligence that controls the components; – the process of creating a hierarchical system will be simplified, so it will be possible to use ready-made solutions.","PeriodicalId":33554,"journal":{"name":"Control Systems and Computers","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49505466","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 recent years, military conflicts are moving to a fundamentally new level of development, which is associated with the widespread use of geographically distributed large groups of remotely controlled robotic systems, the rapid growth of information volumes, a significant increase in the speed of its processing, instant messaging to increase situational awareness, management, rapid response, etc. Purpose. The article is devoted to solving an urgent scientific problem — the development of an algorithm for state identification of military objects and personnel. The problems of using modern cryptographic algorithms for state identification, which use data obtained by other stations of the air defense system and radio intelligence, combined in a special network, are considered. Results. A new encryption key exchange protocol and a rationale for choosing a cryptographic algorithm that can be used in real-time systems with low computational performance are proposed. To ensure the stability of the use of electronic warfare tools, it is proposed to use software-defined radio stations based on programmable logic matrices as a hardware basis, since they allow changing the type of signal-code structures, which also applies frequency ranges without replacing radio engineering blocks. Conclusions. With the increase in the number of remotely controlled military equipment objects on the battlefield, the problem of positioning military personnel and equipping them with network communication means requires a review of the methods and algorithms used for state recognition. The paper proposes a new algorithm for state identification of objects and identification of military personnel using symmetric cryptographic algorithms and the use of a secure Protocol for exchanging information received from the network of the Armed Forces of Ukraine.
