N.This paper presents multilayered wideband filter (WBF) 10 GHz based on technology Low Temperature Co-Fired Ceramic (LTCC). WBF uses threedimensionally (3D) coupled helical inductors. WBF exhibits 3-dB bandwidth 9,3…10,6 GHz (1,3 GHz). The size of WBF is 2,31,60,8 mm. The results of modelling were got in electrodynamics package CST MicroWave Studio 2009.Item Automation of radio controling systems in Ukraine(Видавництво Львівської політехніки, 2010) Tararai, Annain this paper is reviewed the role, significance and trends in automation of systems of radio monitoring.Item Quasiinvariant automatic control digital systems of inertia objects(Видавництво Львівської політехніки, 2010) Lvov, Volodymyr; Andrieiev, AnatoliyThe two-connected automatic control digital system (ACDS) and system of ACDS with combined control are examined. The two-connected and combined system of ACDS with work in the mode of tracking and stabilizing are analyzed. The discrete transfer function of two-connected and combined systems are obtained.Item Proposals of using chameleon-signature in Ukrainian prototype of combined PKI(Видавництво Львівської політехніки, 2010) Dolgov, Viktor; Ishchenko, IuliiaIn this thesis imparts a proposition to introduce a chameleon-signature in the prototype of Ukrainian combined PKI.Item Three-and five-level architectures of internet based information systems(Видавництво Львівської політехніки, 2010) Globa, Larysa; Kot, TetianaCharacteristic of Internet based information system (IBIS) is represented it’s the main points of its functioning and design are discussed. The requirements to IBIS information-computation processes [1] are specified and IBIS architecture for requirements satisfaction is suggested.Item Interference filters for the IR-spectrum region(Видавництво Львівської політехніки, 2010) Yaremchuk, I.; Fitio, V.; Bobitski, Ya.The fife-layer structure of dielectric interference filter for the infra-red region of spectrum was researched. The refractive indices optimal and thicknesses of individual layers are obtained for thin-film filter with interference mirror.Item Adaptation time-series analysis to number of calls on the modern telecommunication network(Видавництво Львівської політехніки, 2010) Gannitskiy, IlliyaThis article describes a study the structure of calls on a modern telecommunication networks; such parameter as number of calls is described in detail.Item About the time measurement of radio-waves propagation in atmosphere at nanoseconds accuracy(Видавництво Львівської політехніки, 2010) Antipov, Ivan; Bondar’, Eugenia; Kostyrja, AlexandrMethods for measuring time of radio-waves propagation in troposphere are presented in article. The estimate of measurements is 1-10 nanoseconds for purpose of high-precision synchronization.Item Classification of DCT-based filtered multichannel images(Видавництво Львівської політехніки, 2010) Fevralev, Dmitriy; Lukin, Vladimir; Krivenko, Sergey; Ponomarenko, Nikolay; Kurekin, AndriyMultichannel remote sensing (MRS) data can be passed to customers in different forms: original (raw), pre-filtered, compressed, classified. In this paper, we analyze how pre-filtering of original images can influence classification accuracy of three-channel images using three channels of real life Landsat TM data with simulated noise.Item Research of efficiency of the data transmission telecommunication systems with limited by the frequency stripe and power(Видавництво Львівської політехніки, 2010) Gorbatyy, IvanThe efficiency of the data transmission telecommunication systems with limited by frequency stripe of telecommunication channel and signal power in channel with the use of modern kinds of signal modulation was explored. The results of efficiency of the systems at the concrete kinds of modulation were got. Recommendations in relation to application of definite kinds of modulation in the data transmission telecommunication systems were given.Item Methods of measuring of loading and indexes of quality of service(Видавництво Львівської політехніки, 2010) Tkachenko, Olga; Eremeev, YuriyMeasuring of loading and indexes of quality of service can take place with a purpose: technical exploitation, prognostication of loading; study of streams of loading and quality, accumulation of statistical information. Measuring methods, measurings devices and measured indexes, get out depending on a purpose. The article is presented devoted the methods of measuring of loading and indexes of quality of service, their analysis and comparison.Item Some results of radar signal detections by the use of compressive receiver(Видавництво Львівської політехніки, 2010) Kawalec, Adam; Pieniezny, AndrzejThe paper presents some results of weak, pulsed and continuous radar signals detection by the use of compressive receiver.Item Luciferase-based biobarcode amplification assay(Видавництво Львівської політехніки, 2010) Belobrov, Peter I.; Denisov, Ivan A.; Tumanyan, Artur G.; Esimbekova, Elena; Meshajkina, Ludmila V.; Yakimov, Anton S.; Kratasyuk, Valentina A.The new biotechnical approach to ecological monitoring and medical devices design using biosensor systems based on luciferase enzyme is described.
