Fuzzy logic based method to estimate the risk of alarm system false detection
(Видавництво Львівської політехніки, 2012) Zhengbing, Hu; Nimko, Vitalii; Bykovyy, Pavlo
A method based on fuzzy logic to estimate the alarm system intruder detection/undetection probability was developed. It uses the assessments of different intensity noise barriers and detector’s vulnerability to them. The usage of fuzzy sets and their defuzzification allowed to consider environmental influences in estimation of the intruder detection probability. Such detection probability information is used by specialized software of the optimal alarm systems design.

Features of impulse stabilizer output smoothing filter parameters choosing
(Видавництво Львівської політехніки, 2012) Vojetsa, Olexandr; Semenystiy, Kostyantin; Snitsaruk, Leonid
Voltage ripple factor dependence at the impulse stabilizer output smoothing filter on the voltage mark-to-space ratio, which controls the key element of the stabilizer is investigated. Expressions, which allow to provide rational selection of the smoothing LC-filter elements and size up the amplitude of the ripple voltage at its output are obtained.
Ultrasound energy for biomedicine
(Видавництво Львівської політехніки, 2012) Bubulis, A.; Jurenas, V.; Minchenya, V.
For removing tissues and fragmenting stones, removing clots from blood vessels and other undesirable derivatives which can occur in a person’s body, it is possible to use the ultrasound energy. Usually the energy generated to the environment by the waveguide is transmitted in the form of intensive acoustic waves of high frequency; tissues are destroyed under their influence, under the direct mechanical effect, or because of the phenomenon of cavitation. Within cavitation, in the liquid effect by the ultrasound frequency of big power, microscopic bubbles filled by vapours or cavities occur which expand fast and explode. These explosions are accompanied by intensive local hydraulic impacts which cause destruction of tissues.
