Mesoscale air quality under stagnant synoptic cold season conditions in the Lake Powell area is characterized through climatological, topographical and numerical studies. Using a synoptic climatological classification scheme, it is found that during the winter this region is dominated by stagnant conditions associated with slow-moving high pressure systems. Using topographic analyses, the Lake ...

On February 14, 2005, the University of Colorado School of Law welcomed then-Federal Communications Commission Chairman Michael Powell to present a keynote address at the Silicon Flatirons Telecommunications Program Symposium, ‘‘The Digital Migration: Rewriting the ‘96 Telecom Act.’’ After being introduced by thenColorado Secretary of Innovation and Technology Leroy Williams, Chairman Powell wa...

In the present analysis, the Dufour and Soret effects on unsteady heat-mass transfer of a viscous incompressible Powell-Eyring fluids flow past an expanding/shrinking permeable sheet are reported. The fluid boundary layer develops over the variable sheet with suction/injection to the non-uniform free stream velocity. Under the symmetry group of transformations, the governing equations along wit...

In this communication, we expand upon previous work (S. K. Powell, N. Goldsman, J. M. McGarrity, J. Bernstein, C. J. Scozzie, A. Lelis, J. Appl. Phys. 92, 4053 (2002)), by applying the device model to 6H SiC MOSFETs operating at high temperatures. We compare the model predictions with the device measurements from room temperature to 200C and find agreement.

The Beale-Powell restart algorithm is highly useful for large-scale unconstrained optimization. In this paper, we use an example to show that the algorithm may fail to converge. The global convergence of a slightly modiied algorithm is proved.
