[Purpose] The present study sought to investigate the influence on static and dynamic lumbar stability of bridge exercise accompanied by an abdominal drawing-in maneuver (ADIM) performed on an uneven support surface. [Subjects] A total of 30 participants were divided into an experimental group (15 participants) and a control group (15 participants). [Methods] The experimental group performed br...

This work studies the asymptotic tracking control problem of a vertical take-off and landing (VTOL) aircraft with unknown dynamics external disturbances. The nonlinear VTOL are approximated via introduction radial basis function neural networks. Then, weight update laws designed. Furthermore, parameter presented to deal errors generated during approximation process disturbances system. Moreover...
