These distribution laws are in demand in queuing theory as it provides a big range of changes in the variation coefficient which plays an important role in the average queue delay calculating. There is no data on such generators neither in scientific literature, no in the GPSS WORLD library. Software generator quality evaluation, regardless of the programming language, is usually made according to statistical tests. In this case, chi-squared and Kolmogorov-Smirnov’s tests are used. In addition, the comparison between theoretical and statistical aspects of the corresponding order is provided. Unlike simple distribution laws, for which the use of the above mentioned statistical tests is provided for in well-known software products and does not cause any difficulties, in our case automatic testing is impossible. The well-known packages STATISTICA, STATGAPHICS, Matlab/Simulink, etc. do not provide for the use of the hyper-Erlang and hyper-exponential distribution laws we consider. Therefore, the Pearson statistical test is calculated and checked manually. The presented results should be useful for professionals of discrete event modeling in the GPSS WORLD environment.","PeriodicalId":245247,"journal":{"name":"Infokommunikacionnye tehnologii","volume":"160 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138987200","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 article is devoted to a brief analysis of the available information about the radio lines of unmanned aerial vehicles, solutions in the field of antennas for the equipment of command control radio lines and payload and the study of perspective antennas for the repeaters placed on unmanned aerial vehicles. The review of the general types of antennas that may be installed on unmanned aerial vehicles, including pin, microstrip and spiral ones, as well as antenna arrays based on them, made it possible to substantiate the prospects of using low-profile and spiral antennas for repeaters installed on unmanned aerial vehicles. The studies conducted on the frequency and spatial characteristics of low-profile and spiral antennas have confirmed their sufficient effectiveness. Proposed solutions can be used as a basis for development of perspective antennas for repeaters installed on unmanned aerial vehicles.","PeriodicalId":245247,"journal":{"name":"Infokommunikacionnye tehnologii","volume":"67 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138988249","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}

Definitions of various learning types are given: in-person, distance, interactive, collaborative. Various options of students' work are determined, such as taking notes, questioning, Case method, testing, laboratory and calculation-graphic works. Performance and evaluation criteria are defined for each of the methods. A scale for assessing the complexity of each type of work has been developed. The average integral and complex integral assessments for all criteria have been derived. As a result of comparing the average integral and complex integral assessments, it is shown that interactive learning is the most preferable among the other types of learning considered in this article. Interactive learning contributes to improving the quality of education through the possibility of interaction between participants in the learning process. The possibility of active joint search for information, its discussion, comprehension and application make the interactive learning option more productive in terms of motivation of students.","PeriodicalId":245247,"journal":{"name":"Infokommunikacionnye tehnologii","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122640252","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}

Given the complexity of the system under study, a mathematic simulation was applied. Study purpose: To increase the efficiency of the resuscitation and intensive care unit through possible planning, based on studying the features of the functioning of this type units. Methods: A method of statistical simulation is proposed as a particular method of mathematical modeling for studying the functioning of the resuscitation and intensive care unit, which was not previously used in this direction. Results: During the work, the intensive care unit no. 2 of the Samara Regional Clinical Hospital named after V.D. Seredavin and the business process of the department’s functioning were studied, an averaged process was selected, a statistical study of the business process was carried out, and the distribution laws were identified and evaluated. Some simulation algorithms were developed based on a random number generator for individual random variables, and some statistical indicators were determined, which were calculated during implementation of all these algorithms. Using the specialized AnyLogic tool, we managed to develop a model of resuscitation and intensive care unit work, the number of runs was determined and considered in the program for the possibility of conducting experiments and comparing the data received. An experiment was performed on a model with changing various input data. The data obtained were analyzed, including using specialized software, and some consistent patterns were identified. Practical significance: Directions for optimizing the work of the department were proposed, and mathematical formulas were suggested for predicting and monitoring the operation of an intensive care unit.","PeriodicalId":245247,"journal":{"name":"Infokommunikacionnye tehnologii","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133662539","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}

Therefore, developing algorithms of parametrical synthesis of amplitude-phase modulators with the use of resistive matching four-pole networks is an actual task. In this work, matching provides the set dependence of a relation of modules and a difference of transfer function phases from frequency in two conditions of a nonlinear element defined by two levels of a control signal. The nonlinear part represents a three-pole nonlinear element with a feedback. The interrelations between elements of the classical matrix of transferring in four-pole networks are established, and the formulas for defining resistances of their two-pole units that are optimum by the criterion of amplitude-phase modulation of an outputt signal are determined. The theory of four-pole networks, as well as the methods of matrix algebra, parametrical synthesis of UHF control devices, decomposition and circuit analysis of radio devices are used. The comparative analysis of theoretical results (AFC and PFC of modulators in two states) received by mathematical modelling in the «MathCad» system and of experimental results received by circuit simulation in the «OrCad» and «MicroCap» systems shows their satisfactory coincidence.","PeriodicalId":245247,"journal":{"name":"Infokommunikacionnye tehnologii","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116592545","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}
