Item Ecology of Open Star Clusters(2012-06-13) Lehman, Clarence; Lehman, Fred; Barnes, Richard"Ecology of star clusters" examines the interactions of stars, and what can be gleaned from those interactions about the evolution and ultimate fate of star clusters large and small. Questions like: 1) What is the force that causes small star clusters to expand? 2) Why do the ancient globular clusters have many binary stars? 3) Why are close triple stars so rare?Item Efficient Algorithms for Geographic Watershed Analysis(2012-07-03) Barnes, Richard; Lehman, Clarence; Mulla, David; Galzki, Jacob; Wan, Haibo; Nelson, JoelThis project is to analyze where wetlands and other vegetated buffers can be placed on the landscape to intercept drain waters and help purify them before they reach the natural watershed. The computational problem comes because new LIDAR images have expanded the resolution of geographic digital elevation models (DEMs) up to a thousandfold or more. This in turn has taxed the ability of existing algorithms to process the expanded datasets. Here we explain the project and present new efficient algorithms for parallel and scalar processing that reduce run-times from days on ordinary computers to minutes or second using the new algorithms in a parallel supercomputing environment.Item New Rules for Simulation and Analysis in Ecology, Epidemiology, and Elsewhere(2012-06-13) Lehman, Clarence; Keen, AdrienneAn invisible "phase change" has recently re-shaped computation, in only a few years. Vast memories allow new modeling methods–still being invented and deployed. We apply such methods to epidemiology and ecology, outlined here.
