The theory of finite state machines has been proposed as the tooling that the task of segregating unit loads on board formalization requires. The main advantage of this tooling is a visual presentation of the unified logic of technological process control. As a result, the main elements of a formalized language for the segregation of dangerous goods have been determined, a finite state machine transition graph for reasonable dangerous goods disposition on / under deck has been drawn, and its applicability to two randomly chosen dangerous goods classes' compatibility plan has been substantiated. The model of a deterministic state machine proposed herein is universal, since the scope of its applicability can be expanded, for example, it can be used to automate the control of compliance with the rules for storing dangerous goods in a warehouse area of river and sea ports terminals.","PeriodicalId":267775,"journal":{"name":"2021 Wave Electronics and its Application in Information and Telecommunication Systems (WECONF)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134523951","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 most optimal and fastest way is to deliver by air using an unmanned aerial vehicle. Using a quadrocopter to carry out such a delivery will be the most optimal, since it has a number of important differences from the common aircraft-type drones - this is the possibility of vertical takeoff and landing and the ability to maneuver at low speeds. These differences are very important for the implementation of unmanned air delivery in the city, because it may be necessary to maneuver in narrow openings between buildings. The article briefly discusses the possibilities of using quadrocopters for the delivery of various goods, provides an example of a company engaged in development in this area, and shows the principle of operation of unmanned air delivery. For the practical implementation of cargo delivery, a portable autonomous module was implemented, capable of maintaining a set temperature for a certain time. In existing cooling containers, dry ice is most often used as a cooling element. The use of dry ice creates the following problems - the release of a large amount of carbon dioxide and the possibility of supercooling the cargo, since the temperature is not regulated in any way. Therefore, it is most optimal to use the Peltier element for cooling, since it is quite compact and its operation can be regulated.","PeriodicalId":267775,"journal":{"name":"2021 Wave Electronics and its Application in Information and Telecommunication Systems (WECONF)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115185602","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, the problem of forming high-stable frequency spectrum is urgent during the development of many radio systems. Such advantages of DDS as technological effectiveness, reliability, resistance to destabilizers, extremely small time of frequency switching during frequency tuning, phase discontinuity of formed oscillations, the capability of forming complex broadband signals, the possibility of complete microminiaturization, good repeatability of parameters during the replication allow improving the engineering-and-economical performance of many radio engineering systems considerably. The purpose of the work is to extend functional capabilities of direct digital synthesizers and digital frequency synthesizers, increase their operation speed, improve the «spectral purity» of formed signals and decrease the level of amplitude and phase noises. Research methods. While solving the set tasks, the methods of the signal theory, number theory, probability theory and mathematical statistics as well as mathematical modeling, computer simulation and experimental research were used in the work. Results. In the direct digital synthesizer of frequency-modulated signals, the signal with V-shaped frequency modulation is formed. It is used in radiolocation for the Doppler frequency measurement. The direct digital synthesizer of phase-modulated signals can be used when designing transmitter modulators with digital control of frequency and phase of synthesized oscillations.","PeriodicalId":267775,"journal":{"name":"2021 Wave Electronics and its Application in Information and Telecommunication Systems (WECONF)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116887935","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}

Situations are considered, when, together with the signals reflected from the targets, the array antenna receives signals from independent sources of pulse interference distributed in space. The phase fronts of radio waves are assumed to be flat. Targets and sources of interference are considered to be point like in angular, which allows the signals coming from them to be considered completely spatially correlated. It is assumed that the conditions of space - time narrowband signals are met. Optimization of spatial processing is formulated as the problem of finding the weight vector corresponding to the maximum of the SNR. Under conditions of a priori uncertainty about the number and characteristics of interfering signals, the estimation of the inverse covariance matrix (or its statistical equivalent) is used to form the weight vectors for the sum and the difference channels. Depending on the method for compilation of covariance matrix, a large variety of adaptive algorithms is possible. Interpretation of spatial suppression methods is the formation of compensation beams in the directions to the sources of interference and subsequent weight summation of the signals of the main and compensation beams. This assumes knowledge (or determination) of the number and angular coordinates of the jammers. This problem can be solved with the help of the interference situation analyzer included in the radar structure. Advantage of the method of spatial adaptation with formation of multiple compensating beams is shown.","PeriodicalId":267775,"journal":{"name":"2021 Wave Electronics and its Application in Information and Telecommunication Systems (WECONF)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125979069","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}

Under conditions of aerodynamic heating, the electrical characteristics of thermal protection change significantly, and a melt layer appears on the outer surface [1]–[4]. The electromagnetic energy emitted by the onboard antenna, under conditions of change in the electrical characteristics of thermal protection and taking into account the effect of plasma formation, decreases so much due to losses due to absorption in these media and to reflection from the interfaces of these media that radio communication between the spacecraft and the earth is interrupted. To ensure continuous radio communication on the descent trajectory of the spacecraft, numerous studies are carried out in order to reduce the above-mentioned type of losses [5]–[7] However, when radiation through dielectric thermal protection, part of the radiated energy can be converted into side waves that do not participate in maintaining radio communication. Determination of the lateral wave structure and the power removed by them will make it possible to estimate the losses caused by the action of the lateral waves. In this work, relations are obtained to take into account the effect of side waves on the radiation pattern of a circular waveguide through a flat uniform radio-transparent heat shield.","PeriodicalId":267775,"journal":{"name":"2021 Wave Electronics and its Application in Information and Telecommunication Systems (WECONF)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114388468","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}
