This report addresses the task of meshing point clouds by triangulated elevated surfaces referred to as TIN surfaces. It describes the general features of this approach, and refers to prototype TIN software employed at NIST for research into the analysis
Abstract: Technological trends are increasingly requiring dimensional metrology at size scales below a micrometer. Scanning probe microscopy has unique advantages in this size regime, but width and roughness measurements must be corrected for imaging

The precision in spectroscopy of any quantum system is fundamentally limited by the Heisenberg uncertainty relation for energy and time. For N systems, this limit requires that they be in a quantum-mechanically entangled state. We describe a scalable
This is the third in a series introducing the activity model in the Unified Modeling Language, version 2 (UML 2), and how it integrates with the action model. The previous article addressed the execution characteristics of actions in general, and
