M.; Galkin, S. A.; Nikolaev, I. M.; Kolesnik, V. I.Approaches to a choice of the most informative combinations of signal features are considered. The procedure for a choice of the operating feature dictionary is proposed. Probabilities of true recognition and are estimated.Item A two channels I/Q-demodulator(Видавництво Львівської політехніки, 2012) Slyusar, V. І.; Serduk, P. E.In this article are analyzed one-cascade and multicascade I/Q-demodulators with two channels.Item A сombined LIFO-priority algorithm for overload control of SIP server(Видавництво Львівської політехніки, 2012) Kuzminykh, IevgeniiaIn this paper a simulation model of message service procedure in SIP server in the normal conditions and in the congestion state is represented. The paper proposes local overload control for SIP server applied FIFO discipline in normal state and LIFO discipline with priority service model during overload.Item Absolute cross-section of turbojet aviation engine calculation(Видавництво Львівської політехніки, 2012) Ryabokon, EvgenThe calculation method of three-dimensional model of turbojet aviation engine is offered, thus the form of turbine vanes with spiralling is described like parametric surface. The method allows make the calculation of absolute cross-section (ACS) of turbojet aviation engines with different geometrical parameters. The calculation results of ACS of aviation engine are presented.Item Accelerating the parametric identification of the monod system using explicit and implicit schemas(Видавництво Львівської політехніки, 2012) Pasichnyk, Roman; Pigovsky, Yuriy; Gunderych, OrysiaCurrent study is a research of different schemas identifying the Monod nonlinear stiff ODE. The schemas provide better performance and accuracy in comparison with the classic implicit ODE solvers.Item Action of irradiation on elements of the light-wave communication(Видавництво Львівської політехніки, 2012) Vikulin, Ivan; Kurmashev, Shamil; Panfilov, IvanIn this paper is shown the influence of irradiation on the elements of light-wave communication appear mainly in decreasing of intensity of light which irradiated by a light-emitting diode, and in decreasing of sensitivity of photodetectors.Item Active autonomous repeater for synchronous networks broadcasting standard DVB - T(Видавництво Львівської політехніки, 2012) Gorbylov, YuriyThe work describes the approaches to creating a national network of digital terrestrial television broadcasting standard DVB-T stand-alone repeater with an output power 25 watts.Item Active tunable filters based on C-negatrons(Видавництво Львівської політехніки, 2012) Lazarev, Alexander; Koval, Kostyantyn; Prykmeta, Andriy; Bondaryuk, DenysDesign and research results of active filters on Cnegatron are shown in the paper.
