© 2015, Pleiades Publishing, Ltd. The propagation of acoustic waves in multifractional mixtures of a liquid with vapor-gas and gas bubbles of different sizes and different compositions with phase transitions is investigated. ...

© Published under licence by IOP Publishing Ltd. According to the classical Zipfs law, the word frequency is a power function of the word rank with an exponent -1. The objective of this work is to find multiplicative ...

© 2015 Springer Science+Business Media New York. We present a new mathematical model for oil displacement by water from formations using polymer-dispersed systems. It is based on the classical two-phase filtration model: ...

© Published under licence by IOP Publishing Ltd. The dynamics of acoustic waves in a liquid containing multilayer barrier is studied. Using the subroutine of the fast Fourier transform the calculation of the distortion of ...

The propagation of weak waves in multifractional mixtures of liquid with vapor-gas and gas bubbles of different sizes and different compositions with phase transitions is studied. The dispersed phase consists of N+M fractions ...
