The audible frequency range covers many octaves in which the wavelength changes from being large with respect to dominant features of a space comparatively much smaller. This makes numerical prediction space's acoustic response, e.g. for auralisation, extremely challenging if all frequencies are be represented accurately. Different classes algorithm give best balance accuracy computational cost...

some physical properties such as geometrical, gravimetrical, frictional and aerodynamic features of seeds of desi chickpea and its splits were studied at a moisture content of 8.2 and 9.0% w., respectively from north-western of iran. geometrical and gravimetrical properties including the average length, width, thickness, the geometric mean of diameter, sphericity, 1000-seed weight, unit weight,...
