An Information Model for Building Automation Systems

March 1, 2007
Author(s)
J Schein
An information model of a building automation system (BAS) was created. It encapsulates several views of the system: the device list, network topology, points list, and sequences of operation. The model allows a single persistent representation of a BAS to

Application of Carbon Nanotube Probes in a Critical Dimension Atomic Force Microscope

March 1, 2007
Author(s)
B C. Park, J Choi, S J. Ahn, D H. Kim, L Joon, Ronald G. Dixson, Ndubuisi George Orji, Joseph Fu, Theodore V. Vorburger
The ever decreasing size of semiconductor features demands the advancement of critical dimension atomic force microscope (CD-AFM) technology, for which the fabrication and use of more ideal probes like carbon nanotubes (CNT) is of considerable interest

ASHRAE Standard 62.1: Problems, Perceptions and Panaceas?

March 1, 2007
Author(s)
Andrew K. Persily, Dennis Stanke, Gordon Holness, Richard Hermans
ASHRAE Standard 62 was first published in 1973, with the title Standards for Natural and Mechanical Ventilation [REF]. The most recent version (designated as 62.1 and titled Ventilation for Acceptable Indoor Air Quality) was published in 2004, with some

Building Retrofits for Increased Protection Against Airborne Chemical and Biological Releases

March 1, 2007
Author(s)
Andrew K. Persily, Robert E. Chapman, Steven J. Emmerich, William S. Dols, Heather Davis, Priya D. Lavappa, Amy S. Rushing
Due to concerns about potential airborne chemical and biological (chembio) releases in or near buildings, building owners and managers and other decision makers are considering retrofitting buildings to provide some degree of protection against such events

Characterization of an Optical Time Domain Reflectometer Calibrator

March 1, 2007
Author(s)
Donald R. Larson, Nicholas G. Paulter Jr., Kenneth C. Blaney
We report the results of an investigation into the signal characteristics and behavior of an instrument used to calibrate Optical Time Domain Reflectometers. This instrument implements the Telecommunications Industry Association standard TIA/EIA-455-226

Development of an Experimental Database and Kinetic Models for Surrogate Jet Fuels

March 1, 2007
Author(s)
M Colket, T Edwards, S Williams, N Cernansky, D L. Miller, Fokion N. Egolfopoulos, P Linstedt, Ram Seshadri, F L. Dryer, C K. Law, Daniel G. Friend, David Lenhert, Heinz Pitsch, A Sarofim, M Smooke, Wing Tsang
The engineering and scientific community ha been searching for the identification of surrogate fuels that can reasonably represent the performance and emissions behavior of jet fuels (e.g. Jet A and JP-8) in engines. Many proposals exist in the literature

Guide for the Selection of Chemical, Biological, Radiological, and Nuclear Decontamination Equipment for First Responders

March 1, 2007
Author(s)
Alim A. Fatah, Richard Arcilesi, Adam Judd, Laurel O'Connor, Charlotte H. Lattin, Corrie Y. Wells
The primary purpose of the Guide for the Selection of Chemical, Biological, Radiological, and Nuclear (CBRN) Decontamination Equipment for Emergency First Responders is to provide emergency first responders with information to aid them in the selection of

Multiscale Model of Germanium Quantum Dots in Silicon

March 1, 2007
Author(s)
David T. Read, Vinod Tewary
Atomic displacements, strains and strain energies in the neighborhood of near-spherical, coherent germanium ¿quantum dots¿ (QD) in crystalline silicon and near a 001} Si surface have been predicted by multiscale modeling, using a combination of classical

Nonparametric Inference for Balanced Randomization Designs

March 1, 2007
Author(s)
Andrew L. Rukhin
The properties of two balanced randomization schemes which allocate the known number of subjects among several treatments are compared. According to the first procedure, the so-called truncated multinomial randomization design, the allocation process
