... The aim of the present study - to increase operation life of propellers by means of creation of hardened case of the surface and decrease the surface roughness, which to be effected without hand accurate grinding. ... For investigation of UF influence on roughness and surface strength of materials, БрА9Ж4Н4 bronze and 0Х14НДЛ stainless steel samples were taken, which are used in fabrication of propellers. ...
... Gas bubbles in living tissues, when subjected to therapeutic ultrasound (TUS), may be found in relatively large cavities such as blood vessels, in intercellular spaces and within cells. ... For greater TUS intensity, when bubble might collapse near a surface, we study bubble behavior in confined space that simulates a tiny cavity such as intercellular space. ... In some cases, the bubble divides into two symmetrical bubbles that collapse while high velocity jets are generated, aiming at the walls. ...
... There are different techniques available that may be used to achieve an effect of focusing of acoustic energy. ... Although such type of array is known, there are comparatively little available experimental data concerning the radiation of finite amplitude wave by it. The aim of the paper is to present results of examination, both experimental and numerical, of the pressure field of the arrays composed of axisymmetric areas of different structure radiating the finite amplitude wave. ...
... Focusing of Finite-Amplitude Waves at Fold Caustics . ... The focusing of acoustic waves at a fold caustic is studied experimentally for different amplitudes of the incident signals. This focusing occurs, for instance, for the sonic boom in case of aicraft manoeuvres. ... The first stage consists in determining the signals to be emitted by an array of piezoelectric antennae in order to obtain the field associated with the caustic to be synthesized, i.e. the Airy function. ...

... Forced Nonlinear Waves Governed by Inhomogeneus Burgers Equation . ... Excitation and propagation nonlinear processes governed by inhomogeneous Burgers equation with non-zero right-hand-side (r-h-s) are considered. By use of characteristics method both qualitative and quantitative properties of solutions for arbitrary forms of r-h-s are studied. ... Concequently, we observe the nonlinear "chaos-order" transformation. ...

... Free Damped Vibrations of a Nonlinear Rectangular Thin Plate under the Conditions of Internal Combined Resonance . ... Using the constructed solutions, the influence of initial conditions on the energy exchange mechanism taking place between the vertical and flexural modes is analyzed, which is intrinsic to free vibrations of nonlinear structures being under the conditions of different internal resonances. ...

... From Fundamental to Application of Ultrasound for Water Treatment . ... Since 1990 there is a growing interest of ultrasound use in processes for water treatment. Propagation of an acoustic wave in water can conduct to elimination of organic contaminants through direct thermal mineralization or induced chemical modification. ... A molecule that exhibits high vapor pressure properties will be destroyed thermally into the bubble of cavitation. ...
