One of the most challenging problems in managing large networked systems is the complexity of security administration. This is particularly true for organizations that AWeb (WWW) servers. Today, security administration is costly and prone to error because
Federal Implementation Guideline for Electronic Data Interchange ASC X12 003040 Transaction Set 822 Customer Account Analysis
The ASC X12 003040 Transaction Set 822 Customer Account Analysis, Implementation Convention defines the Federal Government's interpretation of the use of ASC X12 003040 standards. This implementation convention provides the information necessary for the
Characterization of Coplanar Waveguide on Epitaxial Layers
We examine the effect of thin AlInAs/GaInAs epitaxial layers on the propagation of electrical signals in coplanar waveguide transmission lines fabricated on semi-insulating indium phosphide substrates. We show that argon isolation implants effectively
Noise-Temperature Measurement System for the WR-28 Band
The NIST Noise Project has constructed and tested a radiometer for the measurement of noise sources in the WR-28 waveguide band (26.5 GHz to 40 GHz). It is a total-power radiometer which incorporates a six-port reflectometer for the measurement of relevant

Embedded multiconductor transmission line characterization
This paper presents a measurement method that characterizes lossy printed multiconductor transmission lies embedded in transitions, connectors, or packages with significant electrical parasitics. We test the method on a pair of lossy coupled asymmetric
This paper presents a measurement method that completely characterizes lossy printed multiconductor transmission lines. It determines not only the matrices of impedances and admittances per unit length describing the transmission line in the conductor
A recently developed electrothermal network simulation methodoogy is used to analyze the behavior of a full-bridge, pulse-width modulated (PWM), voltage-source inverter, which uses insulated gate bipolar transistors (IGBT's) as the switching devices. The
