Atmospheric acoustic remote sensing.9780849335884 Atmospheric acoustic remote sensing Deriving digital models of an area on the earth. Using special cameras from airplanes or satellites, either the sun's reflections or the earth's temperature is turned into digital maps of the area. . Bradley, Stuart. CRC (Cyclical Redundancy Checking) An error checking technique used to ensure the accuracy of transmitting digital data. The transmitted messages are divided into predetermined lengths which, used as dividends, are divided by a fixed divisor. / Taylor & Francis 2008 271 pages $119.95 Hardcover QC871 Used to determine wind speed, wind direction and turbulence in the atmosphere, sonic detection and ranging (SODAR SODAR Sound Detection and Ranging SODAR Sonic Detection And Ranging SODAR Sound, Distance and Ranging SODAR Sum of Double Bonds and Rings (chemistry) SODAR Simultaneous Opposite Direction Aerial Refueling (US DoD) ) systems and radio acoustic sounding systems (RASS RASS ROSAT All-Sky Survey RASS Radio Acoustic Sounding System RASS Richmond Agitation Sedation Scale RASS Resource Allocation Selection System (US Army) RASS Relief Association of Southern Sudan ) apply sound waves as a methods of measurement. Devices with these features are increasingly popular in environmental applications as well to determine such measurements as ground-level pollution. Bradley (physics, U. of Auckland) reviews the basic science behind these systems first, then describes the working environment, which is atmosphere near the ground and sound in the atmosphere, and examines sound transmission and reception, SODAR systems and signal quality, SODA signal analysis, RASS systems, and applications in environmental and boundary layer boundary layer In fluid mechanics, a thin layer of flowing gas or liquid in contact with a surface (e.g., of an airplane wing or the inside of a pipe). The fluid in the boundary layer is subjected to shear forces. research and measurements of wind power and loading, complex terrain and sound speed. For students and nonspecialist professions he gives the requisite mathematical background and also gives sample data sets and MatLab codes. Especially handy is an appendix on the installation of SODAR or RASS. ([c]20082005 Book News, Inc., Portland, OR) |
