Decentralized control of region for nonlinear composite systems with input saturation is studied by using Lyapunov's theory and matrix norm properties.

Using comparison theorem and some properties of the matrix norm and the matrix measure, the paper provides several stability conditions for single and symmetric composite uncertain delay systems.

Fuel tube for the CA488 gasoline engine has been developed according to the norm of Volks Wagon Automotive Company, Germany for flexible fuel hose made of composite rubber.
