Ocean surface duct propagation. II. A simple accurate model for surface duct propagation loss [PDF]
The Journal of the Acoustical Society of America, 1978 A simple accurate model has been devised for ocean surface duct propagation. The model assumes the following form for the propagation loss: P.L. = 60 + 10 logrT + 10 logr − “gain,” where the transition range from spherical to cylindrical spreading, rT, is computed from the limiting ray for the duct, and the “gain” term is computed using the normal ...

The Stable Trajectory Tracking Control of a Skid-Steered Mobile Platform with Dynamic Uncertainties
International Journal of Advanced Robotic Systems, 2015 In order to clean the surfaces of air ducts in underground facilities, recent research has been conducted on driving the control and development of an autonomous mobile duct-cleaning platform. The duct-cleaning robots removes contaminants that are inside
