It is proposed to organize the collection of raw materials on the basis of the concept of the IoT, which combines technical solutions for obtaining information and strategies for its processing. Innovation in maximizing profits is the use of raw materials for biogas reactors of grain crops, the further cultivation of which is economically inappropriate. The predicted low quality of cereals is primarily due to a shortage of nitrogen feed, the assessment of which is proposed to be carried out with the help of UAV. The questions were concerning the metrological support of the sensory equipment with the use of cameras with standard and infra-red lenses are considered. A laboratory evaluation of spectral channels was performed on an example of a camera GoPro HERO4. Prospective indexes for cultivating crops are presented, for example, corn and continuous seeding on wheat. The expediency of using in the construction of stress indices for UAV integral indexes that takes into account both spectral and dimensional parameters of plantations of grain crops is proved. Separate consideration is given to the choice of the optimal routes for combines for harvesting plantings in fields based on electronic maps obtained with the use of UAVs. The technique of determination of the amount of transport equipment for providing a harvesting campaign is proposed.","PeriodicalId":6764,"journal":{"name":"2019 IEEE International Scientific-Practical Conference Problems of Infocommunications, Science and Technology (PIC S&T)","volume":"34 1","pages":"561-566"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82733617","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}

Mathematical models of the design problems reducible to covering of a circle object by circles are built. They are based on extracting a combinatorial structure of a new type connected with multipermutatons, on exploiting new geometric properties of objects involved, as well as on applying a continuous functional representation theory for modeling of the multipermutation set. Also, a Method of Artifical Space Dilation was used for constructing one of the mathematical models in extended space. This model is a global optimization one, which is the most promising in terms of obtaining a local optimum close to a global one. The models presented are generalized directly onto problems of covering a circular object by smaller circular objects that allows to cover a much wider class of the design problems regarding their mathematical modeling and solving by continuous and discrete optimization methods.","PeriodicalId":6764,"journal":{"name":"2019 IEEE International Scientific-Practical Conference Problems of Infocommunications, Science and Technology (PIC S&T)","volume":"80 1","pages":"300-304"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87361069","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}

Pastushenko","doi":"10.1109/PICST47496.2019.9061260","DOIUrl":"https://doi.org/10.1109/PICST47496.2019.9061260","url":null,"abstract":"The issues of improving the reliability of storing various resources, access to which is carried out using telecommunication networks, are considered. In this case, the first barrier in ensuring access reliability is the user authentication system. Lately, access systems based on biometric features of a user have been used. Initially, static biometric features of a user (facial image, finger papillary pattern and iris) were preferable, which did not meet the expectations of developers and users due to the simplicity of their falsification. Recently, the preference has been given to the dynamic (behavioral) biometric features of a user, namely voice authentication systems became more widely used. As it is known, voice authentication systems have several advantages, such as: simplicity, convenience, compactness, low cost, and a number of others. In addition, the passphrase can be quickly changed and expanded during the authentication process. However, the quality indicators of all biometric access systems do not meet the increasing requirements. The object of the study is the process of digital processing of voice signal during user authentication in access systems.In the process of voice authentication, the analysis of the amplitude-frequency spectrum of recording materials is performed. At the same time, the main research focuses on the use of estimates of formants, cepstral coefficients, mel-frequency cepstral coefficients, linear prediction coefficients, etc. as a user’s template. On the basis of user’s established patterns, admission decisions are made using Gaussian Mixture Models, Support Vector Machines, Hidden Markov Models or artificial neural networks.In the report, it is proposed to change the paradigm of digital processing of user voice signals and supplement the analysis of the amplitude-frequency spectrum with studies of phase data, which are traditionally ignored during the authentication. According to the authors, the latter is caused by the lack of effective procedures for the formation of phase data, the requirement of additional computational resources, which were not always available to researchers, and some features using the signal phase.","PeriodicalId":6764,"journal":{"name":"2019 IEEE International Scientific-Practical Conference Problems of Infocommunications, Science and Technology (PIC S&T)","volume":"11 1","pages":"621-624"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83621270","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}

First, expressions for memory consumption are introduced. The second part is devoted to analysis of the system throughput. Different architectures for memory organization have been considered in the paper as well as all stages of the cipher pipeline. The architectures are characterized by the different level of parallelism on the level of message processing that results in variations in throughput value. The work presents generalized expression for throughput estimation for all the considered cipher architectures.
