Using the method of wavelet extrapolation based on Haar-wavelet, the results of prediction of self-similar traffic are obtained. We compared the results of traffic prediction based on the Haar-wavelet and the cubic spline function using wavelet and spline extrapolation. This will allow you to choose one or another extrapolation method to improve the accuracy of the prediction, while ensuring scalability and the ability to use it for various IoT applications to prevent network overloads.","PeriodicalId":6754,"journal":{"name":"2019 International Conference on Information and Telecommunication Technologies and Radio Electronics (UkrMiCo)","volume":"14 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72860529","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}

Our scanning electron microscopy based studies suggest the formation of pores with a diameter of up to several micrometers that promotes penetration into the porous layer of macromolecules of the toxic gases. Electrical properties of the obtained structures in the modes of direct and alternating currents are investigated using current-voltage characteristics and impedance spectroscopy. Significant dependence of electrical parameters of the sensory elements on the presence in the atmosphere of molecules of morpholide of pelargonic acid is registered. The adsorption sensitivity of the obtained structures is calculated to estimate their sensory properties. It is found that maximum sensitivity of the sensory elements to the molecules of morpholide of pelargonic acid is realized in the range of their concentrations of about 0.4–0.5 %.","PeriodicalId":6754,"journal":{"name":"2019 International Conference on Information and Telecommunication Technologies and Radio Electronics (UkrMiCo)","volume":"14 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82301841","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}

This principle consists in arranging second-order BPFs at different levels, which lids in multilevel coupling structure. This placement of second-order BPFs minimizes the parasitic interaction between non-adjacent resonators in microstrip filters, which reduces distortion of frequency responses. This placement principle is used to create of two microstrip fourth-order BPFs, obtained by cascading two second-order BPFs with stepped-impedance resonators (SIRs) and mixed couplings. Two mixed couplings lead to two transmission zeros fz1, fz2. The possibility of moving fz1, fz2 with respect to centre frequency f0 and the problem of obtaining the minimum interval between fz1, fz2 and f0 are studied. The measured and simulated responses of microstrip fourth-order BPFs are presented.","PeriodicalId":6754,"journal":{"name":"2019 International Conference on Information and Telecommunication Technologies and Radio Electronics (UkrMiCo)","volume":"29 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83872665","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 analysis of subjective and objective estimation methods is presented. The justification for choosing an objective method of measuring is presented. A list of existing goals and objectives, which face the current progress of the implementation of promising systems for broadcasting and improvement of existing ones are reported. The latter include the absence of normative documents and recommendations for optical specimens for testing tables, etc. Research related to the choice of optical samples from existing sets of colors from a number of international documents and recommendations are presented. Deficiency of these sets is substantiated, as some of the colors necessary for evaluation of telecommunication paths cannot be provided with no color of sets. Provides recommendations and refinements about which colors from existing sets should be used and what constraints exist when used and how to solve. It is shown, that saturated colors of green and red colors are not provided with spectral from the existing sets, therefore, it is proposed to expand the traditional understanding of metrological means by using atlases of colors. Satin colors in contrast to existing ones have a number of advantages and can be used for evaluation in advanced conditions, rather than in the studio that is rigidly defined by the regulations. It is noted that for different brightness values there are a different number of testing points. The number of testing points directly depends on the evaluation criteria and is driven by several possible sets of colors for evaluation. Recommendations for other evaluation conditions are provided. Satin colors are used to construct testing tables.","PeriodicalId":6754,"journal":{"name":"2019 International Conference on Information and Telecommunication Technologies and Radio Electronics (UkrMiCo)","volume":"40 2","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91555080","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}
