Title  Cognitive Underwater Acoustic Networking Techniques 
Author(s)  Sotnik, Dimitri;Goetz, Michael;Nissen, Ivor 
Publication  Berlin, Heidelberg, Springer Berlin Heidelberg, 2020. 
Description  XI, 81 p. 25 illus. in color : online resource 
Abstract Note  This book summarizes the latest research on cognitive networklayer methods and smart adaptive physicallayer methods in underwater networks. Underwater communication requires extendable and delaytolerant underwater acoustic networks capable of supporting multiple frequency bands, data rates and transmission ranges. The book also discusses a suitable foreground communication stack for mixed mobile/static networks, a technology that requires adaptive physical layer waveforms and cognitive network strategies with underlying cooperative and noncooperative robust processes. The goal is to arrive at a universally applicable standard in the area of Underwater InternetofThings [ISO/IEC 30140, 30142, 30143].

Title  Turbulence Nature and the Inverse Problem 
Author(s)  Pyatnitsky, L. N 
Publication  Dordrecht, Springer Netherlands, 2009. 
Description  XVI, 197 p : online resource 
Abstract Note  Hydrodynamic equations well describe averaged parameters of turbulent steady flows, at least in pipes where boundary conditions can be estimated. The equations might outline the parameters fluctuations as well, if entry conditions at current boundaries were known. This raises, in addition, the more comprehensive problem of the primary perturbation nature, noted by H.A. Lorentz, which still remains unsolved. Generally, any flow steadiness should be supported by pressure waves emitted by some external source, e.g. a piston or a receiver. The wave plane front in channels quickly takes convex configuration owing to Rayleigh's law of diffraction divergence. The Schlieren technique and pressure wave registration were employed to investigate the wave interaction with boundary layer, while reflecting from the channel wall. The reflection induces boundarylayer local separation and following pressure rapid increase within the perturbation zone. It propagates as an acoustic wave packet of spherical shape, bearing oscillations of hydrodynamic parameters. Superposition of such packets forms a spatiotemporal field of oscillations fading as 1/r. This implies a mechanism of the turbulence. Vorticity existing in the boundary layer does not penetrate in itself into potential main stream. But the wave leaving the boundary layer carries away some part of fluid along with frozenin vorticity. The vorticity eddies form another field of oscillations fading as 1/r2. This implies a second mechanism of turbulence. Thereupon the oscillation spatiotemporal field and its randomization development are easy computed. Also, normal burning transition into detonation is explained, and the turbulence inverse problem is set and solved as applied to plasma channels created by laser Besselian beams

Title  Astrophysical Disks : Collective and Stochastic Phenomena 
Author(s)  Fridman, Aleksey M;Marov, Mikhail Ya;Kovalenko, Ilya G 
Publication  Dordrecht, Springer Netherlands, 2006. 
Description  XVI, 358 p : online resource 
Abstract Note  The book deals with collective and stochastic processes in astrophysical discs involving theory, observations, and the results of modelling. Among others, it examines the spiralvortex structure in galactic and accretion disks , stochastic and ordered structures in the developed turbulence. It also describes sources of turbulence in the accretion disks, internal structure of disk in the vicinity of a black hole, numerical modelling of Be envelopes in binaries, gaseous disks in spiral galaxies with shock waves formation, observation of accretion disks in a binary system and mass distribution of luminous matter in disk galaxies. The editors adaptly brought together collective and stochastic phenomena in the modern field of astrophysical discs, their formation, structure, and evolution involving the methodology to deal with, the results of observation and modelling, thereby advancing the study in this important branch of astrophysics and benefiting Professional Researchers, Lecturers, and Graduate Students
