Exploitation of system does not provide for maintenance and therefore the using procedures of reconfiguration of the core of structure of “K of N” are examined. Possibilities of models researching two variants of realization of the procedure reconfiguration of the core of structure of “K of N” are demonstrated.Item Line codes generator for learning purposes(Видавництво Львівської політехніки, 2012) Bench, Andriy; Murak, Volodymyr; Velhan, Andriy; Zhelyak, Romanline codes generator used for learning of students of radio and communication engineering majors was described in this article.Item Principles of construction and application of modern microwave wireless energy transmission systems(Видавництво Львівської політехніки, 2012) Gomozov, A. V.; Shokalo, V. M.; Gretskih, D. V.; Аl - Sammarraie, Sh. F. А.; Lukavenko, O. S.results of investigations of construction principles of the modern wireless energy transmission (WET) microwave systems on the basis of the multi-position system of emitters (MSE) with focusing of single-stage discrete V-shape multifrequency signals and double-layer microstrip rectenna with circumpolarization in KHNURE are shown. Two variants of such systems are considered: for the power supply of ground objects in remote areas, and for low-orbit small (LOS) space vehicles (SV).Item Simple E1 software synchronization algorithm based on the windows PIPE concept(Видавництво Львівської політехніки, 2012) Dorozhovets, Yuriy; Klymash, MykhailoThis work demonstrate algorithm invented for software realization at Windows PC, and demonstrate principles of E1 stream synchronization handling particular for fractional E1 to.Item Mathematical description of TCP-sessions using AQM-algorithms for nonlinear packet drop model(Видавництво Львівської політехніки, 2012) Starkova, Olena; Andrushko, DmytroIn this paper a mathematical description of TCPsessions using AQM-algorithms for nonlinear packet drop model is proposed. The novelty of the model is that it makes it possible to describe the dynamics of multiflow data exchange based on AQM/TCP-algorithms.Item Research of rise of coherentness of treatment of signals at active radiolocation on the basis of algorithms of adaptive filtration(Видавництво Львівської політехніки, 2012) Babiy, Juliya; Karpova, Lesya; Kolesnik, MaksimThe method of forming of radiolocation portraits of aims (RLPA) is examined on the basis of algorithms of adaptive signals processing, utilizing of what gives an opportunity to implement radar identification of aims and realize coherent processing of signals at application of non- coherence sources of sounding signals.Item High-voltage power supply based on piezoelectric transformer(Видавництво Львівської політехніки, 2012) Kryvoshei, Dmytro; Paerand, YuriyHigh-voltage power supply based on piezoelectric transformer instead of traditional electromagnetic transformer is offered in the paper.
