MAGNET SYSTEMS -- MTG -- HTS-MAGNET SYSTEMS
Аннотация: Superconducting levitating and rotating systems such as a levitated superconducting ball above a permanent ring magnet, and a levitated ball magnet above a superconducting MTG ring, have been investigated. It is shown that the dependence of the levitating force versus distance between levitated ball and ring has hysteresis and several maxima. Under AC magnetic field, the levitated ball sample oscillates stably at certain conditions. Amplitude-frequency curve has several maxima. At certain frequencies of AC magnetic field, the levitated ball begins to spin. The criteria of superconducting materials that suitable for stable gyro systems are given

NONEQUILIBRIUM PHASE TRANSITIONS -- 1/f-NOISE
Аннотация: 1/f and 1/f(2) noise were observed experimentally in film boiling of water on vertically oriented platinum heater. Fluctuations with a 1/f(alpha) spectrum were observed in a wide range of controlling parameters and seen over five orders of magnitude in frequency. It was noted that the process investigated is similar to the phenomenon of self-organized criticality

SELF-ORGANIZED CRITICALITY -- 1/f FLUCTUATIONS -- POWER SPECTRA
Аннотация: Oscillatory combustion regimes were experimentally investigated under the conditions of ignitable liquid boiling-up before the reaction front. Fluctuations with a power spectral density inversely proportional to frequency (1/f-noise) were observed and the power-law character of distribution functions was found. The phenomena are connected with the intersection and interaction of nonequilibrium phase transitions. A mathematical model describing the initiation of 1/f fluctuations at the interaction of a subcritical phase transition and supercritical one in a space-distributed system was suggested

1/f-NOISE -- FLUCTUATIONS -- FLICKER NOISE
Аннотация: Thermal fluctuations under the transition from nucleate to film boiling of water on a wire heater and fluctuations of jet form during an outflow of superheated liquid from a pressure vessel were experimentally investigated. It has been found that power spectrum of the fluctuations has got a low frequency component corresponding to a 1/f law (flicker noise).??The effect given is connected with the occurrence of nonequilibrium phase transitions in the systems: a crisis of heat transfer under the transition from nucleate to film boiling and a crisis of a flow in boiling-up of superheated liquid jet??
