What Customers Want from Kindle Books

January 1, 2010
Author(s)
Nancy Allmang, Stacy M. Bruss
This article summarizes the process that the National Institute of Standards and Technology Research Library followed to gauge customer preference for Kindle book reading devices and content. Features of the Kindle book devices that were used are

Comparison of the NIST and PTB Standards for Air Kerma and Low-Energy X-rays

December 31, 2009
Author(s)
C M. O'Brien, L. Buermann
A comparison has been made of the air-kerma standards for low-energy x-rays at the National Institute of Standards and Technology (NIST) and the Physikalisch-Technische Bundesanstalt (PTB). The comparison involved a series of measurements at the PTB and

Diffusivity and Mobility Data

December 31, 2009
Author(s)
Carelyn E. Campbell
Diffusion is the process by which molecules, atoms, ions, point defects, or other particle types migrate from a region of higher concentration to one of lower concentration. The diffusivity of an atom or diffusion coefficient is the rate at which a

Feature-based Process Planning Based on STEP

December 31, 2009
Author(s)
Thomas R. Kramer, Frederick M. Proctor
This chapter begins by describing characteristics a process planning language should have. Then it discusses the extent to which four process planning languages have these characteristics. The first two of these are STEP standard process planning languages

Performance Evaluation and Metrics for Perception in Intelligent Manufacturing

December 31, 2009
Author(s)
Roger D. Eastman, Tsai H. Hong, Jane Shi, Tobias Hanning, Bala Muralikrishnan, S. S. Young, Tommy Chang
Real-time three-dimensional vision has been rapidly advancing over the past twenty years, leading to a number of successful laboratory demonstrations, including real-time visual servoing, autonomous vehicle navigation , and real-time people and vehicle

Radiochromic Film

December 31, 2009
Author(s)
Christopher G. Soares, Sameul Trichter, Slobodan Devic
Media that turns color upon being irradiated (coloration detectors) were some of the earliest available detectors for ionizing radiation. Besides conventional silver halide photographic media, which aided in the discovery of x-rays by Rontgen, barium

Author(s)
Winnie K. Wong-Ng
The 2009 Materials Research Society (MRS) Spring Meeting took place in San Francisco Moscone Center from April 13 through 17. This large-scale meeting included forty-one technical symposia, nine symposium tutorials, three poster sessions, a popular

Effects of High Flux Neutron Beams on He-3 cells Polarized In-situ with Spin-exchange Optical Pumping

December 30, 2009
Author(s)
E Babcock, Stephen Boag, Maria Becker, W.C. Chen, T E. Chupp, Thomas R. Gentile, G L. Jones, A K. Petukhov, Torsten Soldner, T G. Walker
Polarized 3He produced by spin-exchange optical pumping (SEOP) has potential as a neutron spin filter for polarization and polarization analysis in many neutron scattering and neutron particle physics applications. The advantage of the SEOP method is its

Traceability: The Key to Nanomanufacturing

December 30, 2009
Author(s)
Ndubuisi George Orji, Ronald G. Dixson, Bryan Barnes, Richard M. Silver
Over the last few years key advances have been made in the area of nanomanufacturing and nanofabrication. Several researchers have produced nanostructures using either top-down or bottom-up techniques, while other groups have functionalized such structures

Temperature Fundamentals

December 29, 2009
Author(s)
Benjamin K. Tsai, Graham Machin
In this chapter the basic principles of temperature, its definition and measurement are given. Beginning with a brief outline of the fundamental principles, the reader is introduced to the concept of thermodynamic temperature and some of the primary means

Nanofiber Supported Phospholipid Bilayers

December 27, 2009
Author(s)
Feng Yi, Jian Xu, David A. LaVan
This work reports on the creation and characterization of nanofiber supported bilayers to mimic the hydrodynamic, chemical and mechanical environment provided by the actin network which supports natural lipid bilayers within a cell. Lipid bilayers were
