## What is/are Projection Adaptive?

Projection Adaptive - Then, the projection adaptive control law is developed by combining adaptive backstepping and dynamic surface control techniques, which is expected to make the sideslip angle and the yaw rate approaching the ideal ones as closely as possible.^{[1]}The 200- and 600-projection adaptive 4DCBCT acquisition corresponded to 85% and 55% reduction in imaging dose, shorter and similar scan times of approximately 90 s and 236 s respectively, compared to conventional 4DCBCT acquisition.

^{[2]}In this study, a modification to the affine projection adaptive filtering algorithm is proposed which is based on a three-level clipping of the input signal as applied to the weight update process.
