Tokarev Yu.N., Vasilenko V.I., Zhuk V.F., Sokolov B.G., Slipetsky D.Ya. «Acoustical estimation of the antarctic krill swarms spatial distribution and biomass» Морской экологический журнал, № 1, с. 5-14 (2005)

The method of acoustic express-evaluation of the krill (Euphausia superba Dana) population spatial structure and determination of its accumulations biomass, with 80 kHz echosounding frequencies has been worked out during the 7-th Ukrainian Antarctic expedition. The method error does not exceed 10%, which permits to recommend it for usage under the Antarctic krill fishery conditions. The principal possibility to acoustically express-evaluate chorological structure of the Antarctic krill population has been shown. Formation by krill of dense accumulations of different form, elongated for 6 miles, appeared to be an expressed feature of krill behaviour during observations. The school type in krill distribution was observed as well. Parallel to this the accumulations location depth varied in the limits of 10–70 m, and their height made from 5 to 50 m.

Viana E.B. «Wheel acoustic simulation: development of a FEM model with infinite elements» Транспорт Урала, № 2, с. 32-35 (2012)

To reduce a three-dimension finite element model of wheel we develop models based of infinite elements. These elements will be user as boundary region, and will be base of the far field calculation. It was used to calculate vibration response by using of FEM established (finite element method), and an the infinite element model is for vibration response velocity achieved from FEM on the wheel as the boundary condition. On previous research, the models were too big and calculation times were really high. With this new report the aim was to develop smaller models that will be suitable to calculate frequencies higher than 1500Hz that was a limit we established for the previous models. This study expected to lay a foundation for an analysis and design optimization of acoustic radiation for random vibration wheel.

Vikulin A.V., Dolgaya A.A., Vikulina S.A. «Geodynamic waves and gravity» Geodynamics & Tectonophysics, № 1, с. 291-303 (2014)

Gravity phenomena related to the Earth movements in the Solar System and through the Galaxy are reviewed. Such movements are manifested by geological processes on the Earth and correlate with geophysical fields of the Earth. It is concluded that geodynamic processes and the gravity phenomena (including those of cosmic nature) are related. The state of the geomedium composed of blocks is determined by stresses with force moment and by slow rotational waves that are considered as a new type of movements (Vikulin, 2008, 2010). It is shown that the geomedium has typical rheid properties (Carey, 1954), specifically an ability to flow while being in the solid state (Leonov, 2008). Within the framework of the rotational model with a symmetric stress tensor, which is developed by the authors (Vikulin, Ivanchin, 1998; Vikulin et al., 2012a, 2013), such movement of the geomedium may explain the energy-saturated state of the geomedium and a possibility of its movements in the form of vortex geological structures (Lee, 1928) The article discusses the gravity wave detection method based on the concept of interactions between gravity waves and crustal blocks (Braginsky et al., 1985). It is concluded that gravity waves can be recorded by the proposed technique that detects slow rotational waves. It is shown that geo-gravitational movements can be described by both the concept of potential with account of gravitational energy of bodies (Kondratyev, 2003) and the nonlinear physical acoustics (Gurbatov et al., 2008). Based on the combined description of geophysical and gravitational wave movements, the authors suggest a hypothesis about the nature of spin, i.e. own moment as a demonstration of the space-time ‘vortex' properties.

Peculiarities of synthesis of systems of suppression of acoustic fields from a position of his automation are considered. The basic attention is given to a technique of construction of bases of knowledge and data on structures of systems of suppression on the bests of a frame-based semantic network, that allows to carry out automated generation synthesis of systems of active suppression. The analysis of the tendencies of development of means and methods of automated designing and computer modeling of systems of active suppression of influence of vibrating and acoustic fields is resulted.
