The scattering problem is treated in the classically rigorous formulation on the base of the integral equation technique. A FPFISG consists of impedance strips located within a plane according to segments which form a certain stage of a self similar fractal’s creation. The main attention is focussed on mathematical model of electromagnetic wave scattering by sparsely FPFISG, which have an explicit solution.","PeriodicalId":211302,"journal":{"name":"2019 IEEE 2nd Ukraine Conference on Electrical and Computer Engineering (UKRCON)","volume":"45 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126118514","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}

Morozov","doi":"10.1109/UKRCON.2019.8879909","DOIUrl":"https://doi.org/10.1109/UKRCON.2019.8879909","url":null,"abstract":"The main information and communication systems (ICS) effectiveness parameters are: reliability, resiliency, network bandwidth, service quality, profitability and cost, malware protection, information security, etc. Most modern ICS refers to multiuser systems, which implement the most promising method of distributing subscribers (users), namely, the code distribution, at which, subscribers are provided with appropriate forms of discrete sequences (signatures). Since in multiuser systems, channels code division is based on signal difference, then the ICS construction and systems performance indicators are determined by the chosen signals properties. Distributed spectrum technology is the promising direction of information security for telecommunication systems. Currently used data generation and processing methods, as well as the broadband signal classes used as a physical data carrier, are not enough for the necessary level of information security (information secrecy, imitation resistance) as well as noise immunity (impedance reception, structural secrecy) of the necessary (for some ICS applications). In this case, discrete sequences (DS) that are based on nonlinear construction rules and have improved correlation, ensemble and structural properties should be used as DS that extend the spectrum (manipulate carrier frequency). In particular, with the use of such signals as the physical carrier of information or synchronization signals, the time expenditures on the disclosure of the signal structure used are increasing and the setting of \"optima\", in terms of the counteracting station, obstacles becomes problematic. Complex signals obtained on such sequences basis have structural properties, similar to random (pseudorandom) sequences, as well as necessary correlation and ensemble properties. For designing signals for applications applied for measuring delay time, signal detecting, synchronizing stations and etc, side-lobe levels of autocorrelation function (ACF) minimization is essential. In this paper, the problem of optimizing the synthesis of nonlinear discrete sequences, which have improved ensemble, structural and autocorrelation properties, is formulated and solved. The use of nonlinear discrete signals, which are formed on the basis of such sequences, will provide necessary values for impedance protection, structural and information secrecy of ICS operation. Increased requirements for ICS information security, formation and performance data in terms of internal and external threats (influences), determine objectively existing technical and scientific controversy to be solved is goal of this work.The paper presents the results of solving the actual problem of performance indicators improvements for information and communication systems, in particular secrecy, information security and noise immunity with interfering influences, based on the nonlinear discrete cryptographic signals (CS) new classes synthesis with the necessary properties.","PeriodicalId":211302,"journal":{"name":"2019 IEEE 2nd Ukraine Conference on Electrical and Computer Engineering (UKRCON)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126638829","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 model provides the possibility to control the indoor climate according to the predefined set point to keep the appropriate temperature. In addition, to evaluate the energy consumption. The current model is designed to provide the ability to take into account the thermal parameters of the particular building, like heat transfer coefficients and heat accumulation rates. The model consists of two main parts one part is used to simulate the thermal behavior of the building and the second part is a centrifugal pump itself. The designed model can be useful for control enhancement of the centrifugal pumping plants operation in heating applications. One of the advantages of the model is the ability to handle changing thermal conditions and compensate it effectively as much as possible. It can help to maintain the preferred indoor temperature despite the change of outdoor weather conditions.","PeriodicalId":211302,"journal":{"name":"2019 IEEE 2nd Ukraine Conference on Electrical and Computer Engineering (UKRCON)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116549895","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 calculation of the objective function vector and constraints are algorithmic and reduces to modeling of the system with nonlinear robust controllers for various modes of the system operation with different input signals and for various values of the plant parameters.

The existing data acquisition (DAQ) system was initially combined with spreadsheet based data processing that did not satisfy the data analysis needs. A modular MATLAB-based data processing and cleaning solution was developed in order to manage the requirements. The prototype solution was developed even further, as it was optimised for speed. As a result, more than 70% program execution speed-up was achieved compared to the prototype program.
