It is suggested that the damping affecting the forced radial oscillations of gas bubbles can be determined very accurately through the measurement of the subharmonic threshold for the oscillations. The advantage of the ...

The characteristics of subharmonic and ultraharmonic modes appearing in the forced, steady?state oscillations of weakly nonlinear systems are considered from the physical, rather than mathematical, viewpoint. A simple ...

A linearized theory of the forced radial oscillations of a gas bubble in a liquid is presented. Particular attention is devoted to the thermal effects. It is shown that both the effective polytropic exponent and the thermal ...

The transient behavior of small?amplitude standing waves on the plane surface of an infinitely deep viscous liquid is investigated. An integro?differential equation of motion for the free surface is derived and solved ...

The collapse of a one-dimensional cavity in a compressible, inviscid liquid is treated exactly. Results of numerical computations for some specific examples are presented.

The nonlinear oscillations of a spherical gas bubble in an incompressible, viscous liquid subject to the action of a sound field are investigated by means of an asymptotic method. Approximate analytical solutions for the ...

A classical theory of the electron, proposed by one of us several years ago and based on finite-difference equations, is discussed by considering the three possible following cases: radiating electron, absorbing electron ...

The transient nonlinear oscillations of a spherical gas bubble in an incompressible, viscous liquid subject to the action of a sound field are investigated by means of an asymptotic method. Approximate analytical solutions ...

A simplified form of the stability equation appropriate for liquids of small viscosity undergoing nearly spherically symmetric flow is derived on the basis of earlier results. This equation is then applied to the analysis ...
