The inviscid fluxes are calculated using the fifth-order weighted essentially nonoscillatory (WENO) scheme, while the central differencing technique is applied to the viscous fluxes.
A solution {[y.sub.n]} of (1) is said to be oscillatory if, for every positive integer [n.sub.0] > 0, there exists n [greater than or equal to] [n.sub.0] such that [y.sub.n][y.sub.n+1] [less than or equal to] 0; otherwise {[y.sub.n]} is said to be nonoscillatory. In the sequel, unless otherwise specified, when we write a functional inequality, it will be assumed to hold for all n sufficiently large.
As usual a solution of (1) is said to be oscillatory if it is neither eventually positive nor eventually negative; else it is nonoscillatory.
Section 2 discussed the oscillatory and nonoscillatory properties of the third-order linear differential equation.
In this paper, an optimized fifth-order symmetric WENO (weighted essentially nonoscillatory) method (WENO-SYM3) based on the three templates is proposed [8-11].
This difference can be explained by the fact that oscillatory shear measurements are limited to small strains where the matrix is still disoriented, whereas in the (nonoscillatory) extension mode the chains can get oriented aided by the adhesion to nanofibers.

In particular, (1) with [lambda]c(t) instead of c(t) is said to be conditionally oscillatory if there exists a constant [[lambda].sub.0] such that this equation is oscillatory for [lambda] > [[lambda].sub.0] and nonoscillatory for [lambda] < [[lambda].sub.0].
For the purposes of this work, two linear PI controllers have been implemented to guarantee a fast and nonoscillatory response of the DC motors.
