The famous Rayleigh criterion describes the minimum distance …

WebThe primary variables that affect depth of field are the focal length of the lens, the aperture setting, the subject or focus distance, and a subjective factor called the circle of confusion, abbreviated as the CoC. The circle of confusion describes the image resolution needed. There are additional considerations for close up (macro) photography. WebThe inversion of Rayleigh surface waves provided a subsurface estimate for the uppermost 8 m of the lunar subsurface with the shear wave velocities varying from 40 to 50 m/s at the surface to velocities in the range of 95–145 m/s with an average of 120 m/s at …

Webcomponents, designers will expect to be guided by criteria of minimum weight, which with elementary calculations, generally leads to a thin-walled structure as an optimal solution. This consideration motivates the emphasis on thin-walled structures, but also demands that students be introduced to the limits imposed by structural instability.
