This note was prepared for a minisymposium on traffic flow at the SIAM Annual Meeting, July 10, 2001. It contains a brief discussion of two traffic flow models that illustrate some interesting aspects of the theory of nonlinear hyperbolic conservation laws. The first is a model of night-time driving that gives a nonconvex flux function in the classical LWR model, but for which the standard Olei...

The microstructure and nanomechanical properties of pure Cr coatings deposited on SiC with various physical vapor deposition (PVD) methods have been investigated for the mitigation hydrothermal corrosion SiC-SiCf (SiC fiber-reinforced matrix) composite fuel cladding in light water reactors (LWR). (4–7 ?m thick) were unbiased substrates using six variants magnetron sputtering processes: (i) stan...

Neon flying squid Ommastrephes bartramii and jumbo Dosidicus gigas are two important commercial ommastrephid species in the Pacific Ocean. As short-lived marine species, squids highly susceptible to changes climate environments. According samples collected from northwest southeast Ocean different years, we explored growth characteristics of these terms their mantle length (ML) distribution rela...
