Directing artillery fire as well as guiding missiles or carrying out target designation (illumination of targets) for high-precision weapons, automatic determination of target coordinates and their prompt transmission to the appropriate ground stations is essential. This article provides a mathematical solution to the issue of determining the motion parameters of a target spotted during surveillance of an area by a reconnaissance drone (UAV). The subject of the study in the article is UAV- rocket-artillery systems. The purpose of the work is to develop a mathematical model for determining the parameters of the target's movement using a UAV. The following tasks are solved in the article: to develop target positioning diagram; to develop a mathematical model for determining the parameters of the target's movement.  The methods used in the article are the methods of mathematical modelling. The following results were obtained: а target positioning scheme has been compiled to determine the coordinates and movement parameters; a mathematical dependence has been developed to determine the coordinates of a fixed target; a mathematical model has been developed to determine the parameters of the target's movement. Conclusions: by calculating the current coordinates of a moving target using the method proposed in this paper, it is possible to determine the coordinates of the target and parameters of the target's movement, including the direction of movement and the trajectory.","PeriodicalId":34701,"journal":{"name":"Suchasni informatsiini sistemi","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42383566","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 purpose of the study is to improve the standard methodology for controlled parameters information value assessing. The proposed method is based on the controlled parameters value probabilities analysis falling into the subintervals of the interval of possible values for different states of the system. When the value of the controlled parameter falls into the left or right boundary subintervals of the compatibility interval for any state of the object, the conclusion about its state is made taking into account possible errors of the first or second kind in this case. When the controlled parameter value enters the central subinterval, useful information appears if the corresponding probabilities for the states H1 and H2 are differ significantly.

Consideration of the system of learning and implementation of the experience of training and application of the Armed Forces from the point of view of the main provisions of the theory of information will allow to increase the effectiveness of the procedure, to determine the ways of improving the indicators of the quality of information. To improve the quality of incoming primary information in the learning and implementing the Armed Forces of Ukraine experience system, it is considered appropriate to develop tools for its collection in the form of detailed questionnaires.

The paper considers the solution of the scientific and practical problem of determining the influence of external factors on the result of non-contact thermal control of biological objects. Object of study. A human was chosen as a biological object. Research progress. Establishing the correlation dependence was carried out in the two most opposite seasons in terms of climate parameters – winter and summer. One person was taken for the study, whose temperature was measured using a FLIR Vue Pro R 640 thermal imager mounted on a Cheerson CX-20 quadcopter at one-hour intervals throughout the day. The data were obtained in the summer period on August 10, 2022. In the winter period, measurements were carried out on January 20, 2022. Research results. Conclusions were made about the absence of a linear correlation between humidity, air temperature and body temperature of BO in the summer period. On the contrary, a high correlation was established between all the indicated parameters in the winter period. Conclusions were made about the need to develop a mathematical model of the factor influence on the thermal control result of the BO in order to obtain analytical ratios for evaluating the quantitative information on each of the temperature control indicators under the factor influence on the conversion function of these indicators. It is noted that such a model will make it possible to rank the indicators of temperature control according to the decrease in their sensitivity to changes in the levels of the temperature control parameter. Usage suggestions. It is proposed to calculate the correcting coefficients to determine the exact value of the body temperature, because it was experimentally established that the values of the body temperature in the winter period differ from the actual values precisely due to the influence of the temperature of the external environment.","PeriodicalId":34701,"journal":{"name":"Suchasni informatsiini sistemi","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135957295","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 main goal is the analysis of text augmentation algorithms, which are significant elements of the developed machine translation system at the stage of improvement of new dictionaries created on the basis of already existing dictionaries. In the course of the work was developed a model of the machine translation system, created dictionaries based on texts and based on already existing dictionaries using augmentation methods such as back translation and crossover; improved dictionary based on algorithms of n-grams, Knuth-Morris-Pratt and word search in the text (such as binary search, tree search, sqrt decomposition). In addition, the work implements the possibility of using the prepared dictionary for translation. Obtained results can improve existing systems of machine translation of the text of artificial languages. Practical significance of this work is the analysis and improvement of text augmentation algorithms by changing the prefix tree type. Compared to the conventional algorithm, the improved algorithm reduced the memory usage by almost 13 times, which allows it to be used on much larger test data. This was achieved by changing the internal system of the node of the prefix tree from constant references to an expandable list.","PeriodicalId":34701,"journal":{"name":"Suchasni informatsiini sistemi","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43878936","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 application of intelligent data analysis allows to reveal the hidden relationship between services. Based on this, a new principle of combining services was formulated.
