Ba0.6Sr0.4TiO3 (BST) and Ba0.6Sr0.4TiO3/Ba(Zr0.2Ti0.8)O3/Ba0.6Sr0.4TiO3 (BST/BZT/BST) multilayer (ML) films were prepared by pulsed laser deposition on the LaNiO3-coated LaAlO3 substrate. X-ray diffraction analysis revealed that the two kinds of films could be epitaxially grown in pure...

The use of reparameterization in the maximization of the likelihood function of the MA(q) model is discussed. A general method for testing for the presence of a parameter estimate on the boundary of an MA(q) model is presented. This test is illustrated with a brief simulation experiment for the...

A new version of the partial autocorrelation plot and a new family of subset autoregressive models are introduced. A comprehensive approach to model identification, estimation and diagnostic checking is developed for these models. These models are better suited to efficient model building of...

A symbolic method which can be used to obtain the asymptotic bias and variance coefficients to order O(1/n) for estimators in stationary time series is discussed. Using this method, the large-sample bias of the Burg estimator in the AR(p) for p = 1, 2, 3 is shown to be equal to that of the least...

The YinNan Irrigation District in NingXia, China diverts each year about 1.6 - 109 m3 water from the Yellow River for irrigation use. More than half of that water is discharged back to the downstream channel or some low-lying depressions as a result of agricultural drainage. Several studies...

In this paper, a roadway controller is designed, analyzed and simulated for a single automated highway lane that achieves desired traffic densities along the lane. A macroscopic traffic flow model that is modified for AHS (Automated Highway Systems) operation is used for control design and...
