A Prototype IEEE 1451.4 Smart Transducer Interface for Sensors and Actuators

August 19, 2011
Author(s)
Yuyin Song, David M. Westbrook, Kang B. Lee
Analog transducers (sensors or actuators) are widely used in industry. The Institute of Electrical and Electronics Engineers (IEEE) 1451.4 standard defines a mixed-mode communication protocol and the Transducer Electronic Data Sheet (TEDS) formats for

CMSD: A Model Supporting Manufacturing and Simulation Application Integration

September 20, 2010
Author(s)
Frank H. Riddick, Yung-Tsun T. Lee
Standard representations for key manufacturing entities could help reduce the costs associated with simulation model construction and data exchange between simulation and other software applications. This change would make the use of simulation technology

Optical Properties of Rod-like Metallic Nanostructures: Insight from Theory and Experiment

September 3, 2009
Author(s)
Jinsong Duan, Kyoungweon Park, Robert I. MacCuspie, Richard A. Vaia, Ruth Pachter
In this work, we combined synthesis of metal Au and Au-Ag core-shell NRs, of high-purity and for a broad range of NR aspect ratios, with theoretical prediction, in order to gain an understanding of the optical response. Self-assembled NRs were also

Restrictions on Transversal Encoded Quantum Gate Sets

March 18, 2009
Author(s)
Bryan K. Eastin, Emanuel H. Knill
Transversal gates play an important role in the theory of fault-tolerant quantum computation due to their simplicity and robustness to noise. By definition, transversal operators do not couple physical subsystems within the same code block. Consequently

Standardization of Auxiliary Equipment for Next Generation CNC Machining

October 17, 2008
Author(s)
David Odendahl, Sid Venkatesh, John L. Michaloski, Frederick M. Proctor
This paper presents the recent work of the Open Modular Architecture Control (OMAC) Machine Tool Working Group to support STEP-NC, which is a new standard for the exchange of comprehensive Computer Numerical Control (CNC) manufacturing data. Because of the

Assessment of Access Control Systems

September 29, 2006
Author(s)
Chung Tong Hu, David F. Ferraiolo, David R. Kuhn
Access control is perhaps the most basic aspect of computer security. Nearly all applications that deal with financial, privacy, safety, or defense include some form of access control. In many systems access control takes the form of a simple password

Securing Voice Over Internet Protocol (IP) Networks

October 1, 2004
Author(s)
Thomas J. Walsh, David R. Kuhn
Voice over IP - the transmission of voice over traditional packet-switched IP networks - is one of the hottest trends in telecommunications. As with any new technology, VOIP introduces both opportunities and problems. Lower cost and greater flexibility are

Shape Analysis of a Reference Cement

October 1, 2004
Author(s)
Edward J. Garboczi, Jeffrey W. Bullard
Recently, techniques for acquiring, analyzing, and using 3-D shape information for aggregates (sand, gravel) have been developed and demonstrated. These mathematical techniques, based on spherical harmonic coefficient analysis, have been applied to x-ray

Analysis of Switching in Uniformly Magnetized Bodies

September 1, 2002
Author(s)
Michael J. Donahue, Donald G. Porter
A full analysis of magnetization reversal of a uniformly magnetized particle by coherent rotation is presented.The magnetization energy of the particle in the presence of an applied field H is modeled as E = ( 0/2)MT DM - 0HTM.This model includes shape

Overview of Communication Standards relating to Motion Control Systems

December 31, 2001
Author(s)
Frederick M. Proctor, John L. Michaloski
This report surveys the international communications standards that affect the application and development of motion control technology. The scope of motion control covered includes applications as diverse as robotics, packaging machinery, discrete parts

The Role of Standards in Innovation

July 1, 2000
Author(s)
Robert Allen, Ram D. Sriram
We review and explore the role of standards in innovation, with particular emphasis on the design and manufacturing processes. We begin by defining and classifying standards and by exploring their role and infrastructure in society. This is followed by a

Contribution of Evanescent Waves to the Far-Field: the Atomic Point of View

April 1, 2000
Author(s)
A Rahmani, Garnett W. Bryant
Evanescent modes of the electromagnetic field are seldom invoked in conventional far-field optics, as their contribution far from the source (say a few wavelengths) is negligible. Contradicting this fact, in recent theoretical works, based on a particular

Digital Library Support for Engineering Design and Manufacturing

September 1, 1999
Author(s)
William Regli
This paper describes our initial efforts to deploy a digital library to support engineering design and manufacturing. This experimental testbed, The Engineeting Design Repository, is an effort to collect and archive public domain engineering data for use
