We focus our attention on using backstepping and control Lypunov Function(CLE)techniques to design and adaptive controller of full state feedback for certain cascade nonlinear systems achieving ainput-to-state stability with respect to unknown bounded disturbance.

This study was conducted to investigate how goal orientation and progress feedback affect excellent and poor writers writing achievement.

In this paper, a new method of eightdirection searching is used to continuously produce such circular arcs,and with the constraint of step direction,the angular points can be avoided.

Theory and structure design of two-ways step running complete fluidic sprinkler of PXSB type;

A specific synchronization of chaotic system Chen is found based on driving parameters, and the reason of positive-synchronization and anti-synchronization has been caught hold of via comparing with Lorenz system and Lü system.
