  • In this paper, we describe our concept for overcoming the data barriers of building credible synthetic populations to assist the transformation between social theories and mathematical models. We specifically developed a 31-million-agent model of Afghanistan s population to demonstrate the ability to computationally control and analytically manipulate a system with the large number of agents (i.e., 108) necessary to model regions at the individual level using the LandScan Global population database. Afghanistan was selected for this case study because gathering data for Afghanistan was thought to be especially challenging. The LandScan Global population database is used by a majority ofmore » key U.S. and foreign agencies as their database system for worldwide geospatial distribution of populations. Assigning attributes to disaggregated population was achieved by fusing appropriate indicator databases using two forms of aggregation techniques geographical and categorical. A new approach of matching attributes to theoretical constructs was illustrated. The other data sources used include data on military and peacekeeper forces loyalties, readiness, and deployment collected through a combination of UN and classified force projections; economic data collected at the national level and disaggregated using data fusion techniques; data on social attitudes, beliefs, and social cleavages through anthropological studies, worldwide polling, and classified sources; and data on infrastructure and information systems and networks.« less
  • Collaborative work between Brookhaven and Los Alamos National Laboratories is developing a new type of linear accelerator that uses a high-power, picosecond pulse CO/sub 2/ laser to irradiate a specialized form of grating with a pitch of 10.6 microns. The electromagnetic field that results can be used to accelerate electrons at field gradients of several GeV/m with potential efficiencies much better than current accelerators. The grating must be conductive to minimize resistive losses, be able to withstand high fields without damage, and requires dimensional tolerances in the sub-micron range. These requirements focus attention on grating material selection, microfabrication methods, andmore » metrological methods used for quality control. At present, several types of gratings have been manufactured by reactive ion etching of fused silica in CHF/sub 3//Ar or etching silicon with KOH/H/sub 2/O or ethylenediamine-pyrocatechol solutions. Metrological analysis of the gratings has begun with a Tracor Northern 5700 digital image analyzer.« less
