Over the past several years, computational scientists have observed a frustrating trend of stagnating application performance despite dramatic increases in peak performance of high performance computers. In and IBM proposed a new process to reverse this situation [1]. This strategy is based on new types of development partnerships with computer vendors(More)
We examine the combustion of mixed H2-CH4-air fuels using two-dimensional simulations that incorporate detailed kinetics and a mixture-averaged model for differential species transport. The mixtures range from lean H2-air at φ=0.37 to lean CH4-air at φ=0.7. For each mixture, we compute the quasi-steady propagation of a flame into flow with superimposed(More)
This paper is the first in a series that presents a combined computational and experimental study to investigate and characterize the structure of premixed turbulent low swirl laboratory flames. The simulations discussed here are based on an adaptive solution of the low Mach number equations for turbulent reacting flow, and incorporate detailed models for(More)
Bethesda, MD – FASEB's MARC (Minority Access to Research Careers) Program has announced the travel award recipients for the Experimental Biology 2007 meeting in Washington, DC, April 28-May 2, 2007. These awards are meant to promote the entry of underrepresented minority students, postdoctorates and scientists into the mainstream of the basic science(More)
1. Diplopia may require a simple change in the patient's glasses, various types of surgical correction, or even treatment for a life-threatening condition. Your job is to determine the urgent nature of the problem and have the patient scheduled in your office, clinic, or hospital appropriately. 2. When questions of diplopia arise, establish whether the(More)
