821. Abstract (Invited)
... Enhancement of the Conversion and Concentration of Energy in a Multibubble Cavitation Zone . ... Following methods have been studied: pulsed modulation of an acoustic field, liquid degassing and cooling, increasing of the static pressure, using different gases for liquid saturation, stimulation of the cavitation by the low frequency field pulses. ... Most of the methods studied cause the increase of the cavitation thresholds and increase of the acoustic and optic transparencies of the cavitation...

822. Abstract (Invited)
... Entropy, Acoustic, and Vorticity Mode Decomposition as an Initial Step in Nonlinear Acoustics Formulations . ... The idea that fluid dynamic disturbances can be decomposed into three fields goes back to Kirchhoff and to Chu and Kovasznay. The labeling of the three fields ensues from that, in the linear limit, the equations governing these fields correspond to thermal (entropy) diffusion, sound propagation, and vorticity diffusion. ...

823. Abstract
... Equations of Nonlinear Acoustics and Weak Shock Propagation . ... The Nonlinear Progressive Wave Equation (NPE) was developed in the 1980's and 1990's as a time domain model for long range shock propagation [McDonald and Kuperman, J. Acoust. ... Its form is quite different from the KZK equation [Zabolotskaya and Khokhlov, Sov. Phys.-Acoust. ... We demonstrate that the NPE and the KZK equation are equivalent within their respective approximations. ...

824. Abstract
... Equivalence Classes and Symmetries of the Variable Coefficient Kadomtsev-Petviashvili Equation . ... We classify variable coefficient Kadomtsev-Petviashvili (VCKP) equation into equivalence classes under the group of local point transformations. We make use of the equivalence group to do this classification and list representatives of equations in each class. We obtain the Lie algebra of the symmetry group of the VCKP equation and discuss several issues concerning symmetries. ...

825. Abstract
... Equivalence Transformations of Maxwell Equations in Rigid Bodies . ... The groups of equivalence transformations for a family of first order equations of the general balance form are investigated. Since the general balance equations involve arbitrary number of independent and dependent variables, their results can be easily applied to all first order partial differential equations. ...

834. Abstract
... The 3rd-order nonlinear piezoelectric constants of relaxor-type perovskites ceramics, 50PNN-35PT-15PZ and 64PNN-36PT, were estimated by dynamic measuring of velocity variation under alternating electric field. ... We have succeed in the generation of acoustic phase conjugate waves through the nonlinear properties of PZT ceramics and obtained the efficiency over 100%, the efficiency being defined as the intensity ratio of the phase conjugate wave to the incident wave. ...

835. Abstract
... Evaluation of the Number of Cavitation Bubbles with Light Scattering . ... It is shown that at moderate amplitude of sound pressure the averaged level of a waveform of scattered light from the bubbles at an antinode of sound pressure increases as content of dissolved oxygen (DO) in distilled water increases, and then it decreases after the maximum appears. At higher amplitude of sound pressure, the maximum of the averaged level shifts towards the lower side of DO content. ...
