Purpose Large optical mirror processing systems (LOMPSs) consist of multiple subrobots, and correlated disturbance terms between these robots often lead to reduced processing accuracy. This abstract introduces a novel approach, the nonlinear subsystem adaptive dispersed fuzzy compensation...

Geometrical properties of fractured basalt and sandstone surfaces are studied by measuring the length distribution of shadows appearing under grazing illumination. For self-affine surfaces, the distribution is predicted to follow a power law of the shadow length with an exponent depending only...
