Computational Metrology

September 1, 1993
Author(s)
Ted Hopp
Coordinate measuring systems (CMSs) assess length-based characteristics of mechanical parts by measuring points on the surface and analyzing the point data. Data analysis software can contribute significantly to the total measurement error of a CMS

Development and Test Results for a Vision-Based Approach to AVCS

September 1, 1993
Author(s)
Maris Juberts, Karl Murphy, M Nashman, H Scheiderman, Harry A. Scott, Sandor S. Szabo
To improve ground transportation, the United States began a program called the Intelligent Vehicle / Highway Systems (IVHS), sometimes called Smart Cars / Smart Roads. One of five IVHS components, the Advanced Vehicle Control Systems (AVCS), envisions

Simple, Compact, High-Purity Cr Evaporator for UHV

September 1, 1993
Author(s)
Jabez J. McClelland, John Unguris, R E. Scholten, Daniel T. Pierce
A simple, compact Cr evaporator is constructed by electroplating Cr metal onto the tip of a W hairpin filament. At 5 cm from the evaporator, deposition rates up to 10 nm min -1 (flux {asymp} 10 19 atoms m -2s -1) have been obtained, with total deposition

Security Issues in the Database Language SQL

Author(s)
William T. Polk, Lawrence E. Bassham
The Database Language SQL (SQL) is a standard interface for accessing and manipulating relational databases. An SQL-compliant database management system (DBMS) will include a minimum level of functionality in a variety of areas. However, many additional

Accurate Transmission Line Characterization

August 1, 1993
Author(s)
Dylan F. Williams, Roger Marks
This letter introduces a new method for the characterization of transmission lines fabricated on lossy or dispersive dielectrics. The method, which is more accurate than conventional techniques, is used to examine the resistance, inductance, capacitance
