A Novel Peak Detection Algorithm for Use in the Study of Machining Chip Segmentation

November 7, 2007
Author(s)
Eric P. Whitenton, Robert W. Ivester, Jarred C. Heigel
The study of how metal deforms and flows as parts are machined yields important insights into the metal cutting process. Improvements in high-speed digital imaging and image processing software promise to improve our understanding of the tool-workpiece

Content-Based Assembly Search: A Step Towards Assembly Reuse

November 7, 2007
Author(s)
Ram D. Sriram, A S. Deshmukh, A G. Banerjee, Satyandra K. Gupta
The increased use of CAD systems by product development organizations has resulted in the creation of large databases of assemblies. This explosion of assembly data is likely to continue in the future. In many situations, text-based search alone may not be

Advanced Technology for Fire Suppression in Aircraft

November 6, 2007
Author(s)
Richard G. Gann
In its decade of systematic research (1997-2006), the NGP revitalized the field of fire suppression science. The NGP arose as a result of a discovery that garnered the Nobel Prize for two accomplished chemists and legislation that turned science into

Influence of the Colloidal Environment on the Magnetic Behavior of Cobalt Nanoparticles

November 6, 2007
Author(s)
Guangjun Cheng, Cindi L. Dennis, Robert D. Shull, Angela R. Hight Walker
The magnetic properties of 10 nm cobalt (Co) nanoparticles in 1,2-dicholorbenenze (DCB) are investigated via a series of magnetization (M) vs. temperature (T) measurements. A rapid rise in magnetization around 250 K during warming and a sudden drop at 240

Planning User-Centered Evaluations for Interactive Information Visualizations

November 2, 2007
Author(s)
Yee-Yin Choong, Theresa O'Connell
This paper describes a user-centered methodology to evaluate innovative, complex interactive visualizations (IVs) developed for information analysis. Our research goal is to develop innovative evaluation methods and sensitive metrics to understand how

A Quantum Algorithm Detecting Concentrated Maps

November 1, 2007
Author(s)
Isabel M. Beichl, Stephen Bullock, David Song
We consider an arbitrary mapping for , some number of quantum bits. Using calls to a classical oracle evaluating and an classical bit data store, it is possible to determine whether is one-to-one. For some radian angle , we say is -concentrated iff for

BACnet at Georgia Tech

November 1, 2007
Author(s)
Donald Alexander, Cornelius Ejimofor, David Holmberg
The Van Leer building at Georgia Tech was selected for a pilot project to study the feasibility of using an RTP-based temperature setback approach to energy savings for the campus. Georgia Tech saved approximately 7000 kWh of power and $1000 using the RTP

BACnet Measures Up

November 1, 2007
Author(s)
Steven T. Bushby
BACnet was developed to enable integration of building automation and control products from multiple vendors and to allow building owners the freedom to by products based on price and performance, rather than compatibility with currently installed building

BACnetRG at Georgia Tech.

November 1, 2007
Author(s)
David G. Holmberg, D P. Alexander, C Ejimofor
Large facility owners generally negotiate yearly or multiyear electric service agreements and often are given lower base rates in exchange for sharing the risk of price fluctuations. This agreement may take the form of a capped rate, or may go as far as a

BACnetRG Measures Up.

November 1, 2007
Author(s)
Steven T. Bushby
The National Institute of Standards and Technology (NIST) has two campus facilities, the main one in Gaithersburg, MD, near Washington, D.C., and a smaller facility in Boulder, Colo. The Gaithersburg facility is 234 hectares (578 acres) and has more than

Characterization and Correction of Stray Light in Optical Instruments

November 1, 2007
Author(s)
Yuqin Zong, Steven W. Brown, G Meister, R Barnes, Keith R. Lykke
Improperly imaged, or scattered, optical radiation within an instrument is difficult to properly characterize and is often the dominant residual source of measurement error. Scattered light can originate from the spectral components of a point source and

Combinatorial Polymer Scaffold Libraries

November 1, 2007
Author(s)
Carl G. Simon Jr., J S. Stephens, Matthew Becker
We have developed a method for fabricating combinatorial libraries of porous, three-dimensional, salt-leached, polymer scaffolds that can be used for screening the effect of scaffold properties on cell response. Syringe pumps, tubing and a static mixer are

Comparison between NIST and AF laser energy standards using high power lasers

November 1, 2007
Author(s)
Xiaoyu X. Li, Thomas Scott, Christopher L. Cromer, David Cooper, Steven Comisford
We report the results of a high-energy laser calorimeter comparison conducted by the National Institute of Standards and Technology (NIST), Boulder, Colorado and the U.S. Air Force Primary Standard Laboratory (AFPSL), Heath, Ohio. A laser power meter, used

Consecutive Neutral Losses of H 2 O and C 2 H 4 O From N-Terminal Thr-Thr and Thr-Ser in Collision-Induced Dissociation of Protonated Peptides. Position Dependent Water Loss From Single Thr or Ser.

November 1, 2007
Author(s)
Pedatsur Neta, Quan-Long Pu, Xiaoyu Yang, Stephen E. Stein
A two-step neutral loss from tryptic peptides containing Thr-Thr or Thr-Ser at their N-terminus is studied. This process also requires a mobile proton (i.e., the number of charges on the peptide is greater than the number of basic amino acids) and leads to

Delivery of Fluorescent Probes Using Iron Oxide Particles as Carriers Enables In Vivo Labeling of Migrating Neural Precursors for MRI and Optical Imaging

November 1, 2007
Author(s)
James P. Sumner, Richard Conroy, Eric Shapiro, John M. Moreland, Alan P. Koretsky
Iron oxide particles are becoming an important contrast agent for magnetic resonance imaging (MRI) cell tracking studies. Simultaneous delivery of fluorescence indicators with the particles to individual cells offers the possibility of correlating optical
