Buffer Management and Priority Scheduling for ATM Traffic Shaping

December 20, 1999
Author(s)
F Duran, T Lizambri, S A. Wakid
The impact of buffer management and priority scheduling is examined in worst case scenarios when the aggregate incoming traffic is higher than the output link capacity of an ATM traffic shaper. To simultaneously reduce cell loss and extreme delay behavior

Ordering/Displacive Phase Transformations in Ca 4 Nb 2 O 9

December 17, 1999
Author(s)
Igor Levin, Leonid A. Bendersky, Robert S. Roth, Terrell A. Vanderah
Four Ca 4Nb 2O 9=Ca(Ca1/3Nb 2/3)O 3 polymorphs based on ABO 3 perovskite-like structure were identified. These polymorphs feature three different arrangements of Ca/Nb cations on B-sites of perovskite. In three of the polymorphs, cation ordering is

A Resource Access Decision Service for CORBA-Based Distributed Systems

December 9, 1999
Author(s)
Konstantin Beznosov, Yi Deng, Bob Blakley, Carol Burt, John Barkley
Decoupling authorization logic from application logic allows applications with fine-grain access control requirements to be independent from a particular access control policy and from factors that are used in authorization decisions as well as access

Using XML in a Software Diagnostic Tool

December 6, 1999
Author(s)
Alden A. Dima
Many development tools such as execution tracing tools generate a large amount of text output. The large quantity of text make it hard for the user to sort through and make sense of the output. In addition, the output is often formatted in a manner that

Differentiated Services Over Cable Networks

December 5, 1999
Author(s)
Nada T. Golmie, F Mouveaux, David H. Su
The current Medium Access Control interface specifications of the Multimedia Cable Network System (MCNS) project describe a best effort access service over cable networks. In this paper, we show that even though these specifications are mainly intended to

Causality and Characteristic Impedance

December 2, 1999
Author(s)
Dylan F. Williams, Bradley K. Alpert
A new causal power-normalized waveguide equivalent-circuit theory fixes both the magnitude and phase of the characteristic impedance of a waveguide.

Modeling Wear of Ceramics Based on Wear Maps

December 2, 1999
Author(s)
Stephen M. Hsu, M C. Shen
Ceramics are increasingly being considered for wear resistant applications. The design and prediction of ceramics wear, however are lacking behind metals. This paper addresses the ability to predict wear of ceramics by examining a large data base of four

A Model of Cerificate Revocation

December 1, 1999
Author(s)
David A. Cooper
This paper presents a model for the distribution of revocation information using certificate revocation lists (CRLs). This model is used to highlight inefficiencies in the traditional method of distribution certificate status information using CRLs. Two

A Modular Architecture for STEP

December 1, 1999
Author(s)
Allison Barnard Feeney, David M. Price
This paper presents the current direction in the architecture of STEP (STandard for the Exchange of Product model data, ISO 10303). STEP is an international standard designed to enable the exchange of product data between heterogeneous computer systems

A New Method to Measure the Distance Between Graduation Lines on Graduated Scales

December 1, 1999
Author(s)
William B. Penzes, Robert Allen, Michael W. Cresswell, L Linholm, E C. Teague
Line scales are used throughout industry for a variety of applications. The most common is the stage micrometer, a small graduated glass scale for the calibration of optical instruments such as microscopes. However, stage micrometers are generally not
