Mapping the risks : assessing the homeland security implications of publicly available geospatial information
Assesses the homeland security implications of publicly available geospatial data and information. Following the attacks of September 11, 2001, many agencies within the federal government began restricting some of their publicly available geospatial data and information from such sources as the World Wide Web. As time passes, however, decisionmakers have begun to ask whether and how such information specifically helps potential attackers, including terrorists, to select U.S. homeland sites and prepare for better attacks. The research detailed in this book aims to assist decisionmakers tasked with the responsibility of choosing which geospatial information to make available and which to restrict.
Demographic Ring Study Reports with GIS Technology
Market analysis that is performed in support of commercial real estate decisions has long included demographic ring study reports. Recent advancements in Geographic Information Systems (GIS) technology has spilled over to ring-study reporting. Contemporary ring studies have detailed breakdowns of populations by subgroup, include expenditure projections by product category, and are available for purchase for use on desktop computers at under $300. Two ring-study products are contrasted here: Site Reporter from CACI and CensusCD+Maps from GeoLytics.
An Optimization Approach to Occupant Safety and Fuel Economy in Vehicle Design
1. Abstract A major challenge in automotive design is the creation of safe vehicles with minimal environmental impact. This study presents a modeling framework for evaluating and optimizing body designs for improved occupant safety and fuel efficiency. Vehicle body mass is considered as the main link between safety and sustainability. The modeling framework includes frontal crash energy absorption, restraint system design and fuel economy. Preliminary results indicate a Pareto-optimal curve between safety and sustainability may exist when other factors are not taken into account. A more complete modeling framework that includes more sophisticated sustainability and safety metrics, cost and other market considerations, is suggested in order to support better design and regulatory decisions. 2.
