A Simulation Analysis of BACnet Local Area Networks

October 15, 2003
Author(s)
W Song, S Hong, Steven T. Bushby
Cnet is a standard data communication protocol for building automation and control systems. BACnet defines an object-base model of the information that is exchanged between components of the building automation system and an application layer protocol that

EMI Characterization with Parasitic Modeling for a Permanent Magnet Motor Drive

October 12, 2003
Author(s)
Xudong Huang, Pepa Elton, Jih-Sheng Lai, Allen R. Hefner Jr., David W. Berning, Shaotang Chen, Thomas Nehl
In this paper , a permanent magnet ac motor drive is tested extensively, and the prominent frequencies are identified for their relationship with the noise sources and their propagation paths. Switching characteristics of the power MOSFETs are evaluated

Picture Password: A Visual Login Technique for Mobile Devices

July 1, 2003
Author(s)
Wayne Jansen, Serban I. Gavrila, Vladimir Korolev, Richard P. Ayers, Ryan Swanstrom
Adequate user authentication is a persistent problem, particularly with handheld devices, which tend to be highly personal and at the fringes of an organization's influence. Yet, these devices are being used increasingly in corporate settings where they

New Tools for Specifying BACnet

March 1, 2002
Author(s)
Steven T. Bushby
The BACnet communication protocol standard makes it possible to integrate a wide variety of building automation and controlproducts. Building owners and the consulting engineering community have had difficulty understanding how to write quality

Analysis of the Impedance Spectra of Short Conductive Fiber-Reinforced Composites

August 1, 2001
Author(s)
J M. Torrents, T Mason, A Peled, S Shah, Edward Garboczi
The presence of small amounts of short conductive fibers in a composite of finite matrix conductivity results in the subdivision of the one matrix impedance arc into two separate low and high frequency arcs in the complex impedance plane. These features

Building Integrated Photovoltaic Test Facility

August 1, 2001
Author(s)
Arthur H. Fanney, Brian P. Dougherty
The widespread use of building integrated photovoltaics appears likely as a result of the continuing decline in photovoltaic manufacturing costs, the relative ease in which photovoltaics can be incorporated within the building envelope, and the fact that

Sensor Networking and Interface Standardization

May 1, 2001
Author(s)
Kang B. Lee
Sensors are used in various industries, ranging from aerospace, automotive, biomedicine, building, industrial automation, manufacturing, and process control to environmental monitoring. Traditionally, sensor outputs are analog signals, which are then fed

Adaptation of Traditional Usability Testing Methods for Remote Testing

January 1, 2001
Author(s)
Jean C. Scholtz
Traditional usability testing methods are difficult to use in producing web sites and web applications mainly because of the decreased development times that companies demand for this type of software. Users of web sites have diverse platforms, computer

Parallel Genetic Programming

June 1, 2000
Author(s)
John G. Hagedorn, J E. Devaney
This project is developing a generic Genetic Programming system that is inherently parallel. Genetic Programming uses Darwinian selection and reproduction to evolve a solution to a problem, where individuals are represented by computer programs. A user

Design and Development of a Dictionary Translator

January 1, 1999
Author(s)
John V. Messina, James A. St Pierre, Michael R. McCaleb
The lack of a traceable set of terminologies to describe electronic components has long been identified by the electronic industry as a significant problem. As part of its Electronic Commerce of Component Information (ECCI) project, NIST's Electronic

Conformance Testing Object-Oriented Frameworks Using JAVA

October 1, 1998
Author(s)
Kevin G. Brady, James A. St Pierre
This paper details the assumptions, decision processes, and conclusions reached during the development and implementation of a Conformance Testing Tool using the JAVA [JAVA] programming language, and the Object Management Group's (OMG's) Common Object

Anisotropy of Interfaces in an Ordered HCP Binary Alloy

September 1, 1998
Author(s)
John W. Cahn, S C. Han, Geoffrey B. McFadden
A multiple-order parameter mean field theory of ordering on a binary hexagonal-close-packed (HCP) crystal structure is developed, and adapted to provide a continuum formulation that incorporates the underlying symmetries of the HCP crystal in both the bulk

Towards STEP-Based Data Transfer in Layered Manufacturing

September 1, 1998
Author(s)
D Dutta, Anil Kumar, Mike Pratt, Ram D. Sriram
This paper concerns the informational requirements of layered manufacturing (LM). The most common industrial use of LM today is for rapid prototyping, but we take a wider view of it as a flexible fabrication technology. Its use in building functional

Automated SIMS for Determining Isotopic Distributions in Particle Polutations

February 1, 1998
Author(s)
David S. Simons, John G. Gillen, Cynthia J. Zeissler, R H. Fleming, P J. McNitt
A System has been developed to make rapid automated measurements of isotopic ratios from many individual micrometer-sized particles dispersed on a substrate. High particle throughput is achieved by using a commercial secondary ion microscope to collect

Issues in Evaluation of Complex Fire Models

January 1, 1998
Author(s)
Richard D. Peacock, Paul A. Reneke, Glenn P. Forney, M. M. Kostreva
Several methods of evaluation of the predictive capability have been applied to fire models, but with limited utility. These range from explicit evaluation of the equations used in simple models such as ASET to pointwise evaluation of complex models from

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
