Role-Based Access Control (RBAC): Features and Motivations

December 15, 1995
Author(s)
David F. Ferraiolo, Janet A. Cugini, David R. Kuhn
The central notion of Role-Based Access Control (RBAC) is that users do not have discretionary access to enterprise objects. Instead, access permissions are administratively associated with roles, and users are administratively made members of appropriate

ADACS: An Advanced Deburring and Chamfering System

December 1, 1995
Author(s)
Keith A. Stouffer, Robert Russell
This paper describes a numerically controlled finishing system, the Advanced Deburring and Chamfering System (ADACS). ADACS employs a user friendly, Graphical User Interface (GUI) to off-line program finishing and chamfering edges and prompt the operator

Implementing Role-Based Access Control Using Object Technology

December 1, 1995
Author(s)
John Barkley
With Role Based Access Control (RBAC), each role is associated with a set of operations which a user in that role may perform. The power of RBAC as an access control mechanism is the concept that an operation may theoretically be anything. This is

Line-Reflect-Match Calibrations with Nonideal Microstrip Standards

December 1, 1995
Author(s)
Dylan F. Williams, J. B. Schappacher
We apply a previously developed Line-Reflect-Match (LRM) calibration that compensates for the nonideal electrical behavior of the match standard to microstrip transmission lines and investigate impedance definitions, standard parasitics, and calibration
