A.; Karpovich, S. E. In the work, a solution to a problem of oscillatory flow of viscous incompressible liquid in a rectilinear pipe of circular section, completely filled with the liquid was presented. The way of solving flow generated by pressure pulsation and the pipe oscillation to the flow direction was also-discussed. The behaviour of the liquid for the selected spectrum of its frequency and viscosity-was further analysed. 2007-01-01T00:00:00Z https://rep.bntu.by/handle/data/73049 Сенсорные микросистемы с RFID идентификацией Колешко, В. М.; Полынкова, Е. В.; Паутино, А. А. Radio frequency identification systems (RFID systems) have already being widely used for a long time in different spheres from access control systems to goods and transport tracking systems. Combining surface acoustic wave (SAW) sensor with radio frequency identification system can result in wireless SAW sensor microsystem or in other words in wireless sensor. This research e.xamines basic constructions of wireless SAW sensor microsystem, formulates its mathematical model and with the help of “RFID SAW Sensor” program computes operational parameters of wireless sensor. 2007-01-01T00:00:00Z https://rep.bntu.by/handle/data/73050 Об устойчивости положения равновесия вводимого протеза при реконструкции среднего уха Михасев, Г. И.; Ермоченко, С. А. The reconstructed middle ear consisting of a thin annular plate made from cartilage, the intact stapes, and a T-type prosthesis replacing the malleus-incus chain is considered. The first problem is to calculate the initial pretension that can be generated by prosthesis longer than the distance between the stapes head and the eardrum. The second one is to investigate possible stable and unstable positions of the prosthesis after its inserting. 2007-01-01T00:00:00Z https://rep.bntu.by/handle/data/73047 Модели взаимодействия колеса с опорной поверхностью в продольной плоскости Широков, Б. Н.; Альгин, В. Б.; Иванов, В. Г. The paper discusses the widespread state-of-the-art statical and dynamic models of contact tyre/surface interaction for friction coefficient determination and simulation. Developing the existing procedures, the fuzzy and neuro-fuzzy models of friction coefficient recognition are proposed. The simulation results are given for models under discussion with a subsequent analysis. 2007-01-01T00:00:00Z
