Best Practices and Standards for Taxonomy Development at Sandia National Laboratories

Miller, Jennifer L.; Moser, Elizabeth C.; Wishard, Lisa

Sandia National Laboratories currently lacks a systematic approach to creating and managing its corporate information; e.g., content management to include metadata standards, taxonomy best practices and style guides. Within this environment, Sandia’s knowledge workers often create and recreate information structures without coordination or collaboration. This document puts forth best practices and standards for taxonomy development at Sandia National Laboratories. It is based on best practices gathered from industry, published industry standards, and the lessons learned from taxonomy projects at Sandia. The document is a direct response to a recommendation made in an FY07 milestone Evaluating the Value of Enterprise Taxonomy at Sandia National Laboratories that “…best practices and standards be developed by the Technical Library staff” (Miller, et. al. 2006).

Ultrasensitive directional microphone arrays for military operations in urban terrain

Okandan, Murat; Parker, Eric P.; Peterson, Kenneth A.; Resnick, Paul; Serkland, Darwin K.

Acoustic sensing systems are critical elements in detection of sniper events. The microphones developed in this project enable unique sensing systems that benefit significantly from the enhanced sensitivity and extremely compact foot-print. Surface and bulk micromachining technologies developed at Sandia have allowed the design, fabrication and characterization of these unique sensors. We have demonstrated sensitivity that is only available in 1/2 inch to 1 inch studio reference microphones--with our devices that have only 1 to 2mm diameter membranes in a volume less than 1cm{sup 3}.
