Yu.; Holyaka, R. L.; Gelzynskyy, I. I.; Marusenkova, T. A.; Levenets, V. V.Design principles and microelectronic parts of sensor devices signal transducers (including thermomagneto-, photo- measuring converters) meeting requirements of up-to-date low-voltage energy-efficient apparatus driven and fed through USB port are considered. It is shown that such sensors in order to providing high technical characteristics have to have possibility of highprecision functional transductions at low-voltage unipolar supply source (5 V or less), consume small power (tens of mW or less) and be compatible with USB interface.Item Multilevel image thresholding based on histograms` peaks clustering(Видавництво Львівської політехніки, 2010) Kosarevych, Rostyslav; Kobasyar, Mykhaylo; Korniy, Valentyna; Rusyn, BohdanThis paper presents an algorithm for finding thresholds by clustering data formed thru detection in different size image parts histogram peaks.Item Progress in the analysis of the electrical generator of the heart(Видавництво Львівської політехніки, 2010) Chaikovsky, Illya; Budnyk, Mykola; Najafian, Mokhammad; Martynenko, Serhiy; Dovbysh, Anatoly; Budnyk, Vitaly; Kovalenko, OleksandrAim of study is to develop understanding of the heart electric generator based on classification of current density distribution (CDD) maps with help of information-extreme intellectual technology (IEIT). Errorfree decision rules were obtained in learning population. Decision rule for test Healthy–CAD was examined based on 203 healthy volunteers and 256 CAD pts and sensitivity and specificity equal to 93% and 87 %, respectively, have been achieved.Item The theoretical basis of bisignal formation of information flow in computer systems with open optical signals(Видавництво Львівської політехніки, 2010) Grynchyshyn, Taras; Yakymenko, Ihor; Nykolajchuk, Yaroslav; Kasyanchuk, MykhajloThe theoretical basis of bisignal formation of information flow in computer systems (CS) with open optical signal (OOS) was proclaimed. Analytic expressions of signals attenuation in computer systems OOS with compensated multiplicative noise were determined.Item Methods and facilities of construction of analog-digital coders of the special processors of the cross-correlation working of signals(Видавництво Львівської політехніки, 2010) Albanskiy, IvanTheoretical bases are expounded and systematized architecture of analog-digital coders of the cross-correlation working of signals.Item Light scattering properties of peptone solution(Видавництво Львівської політехніки, 2010) Kotsyumbas, Ihor; Bilyy, Oleksandr; Getman, Vasyl; Kotsyumbas, Halyna; Kushnir, IhorThe results of researches of light scattering properties of peptone liquid solution for the bacterial cells of Escherichia coli is described.Item Specifics of recognition of signals are on the basis of correlation neuronlike processor(Видавництво Львівської політехніки, 2010) Zavedyuk, T.
