Mosquito Noise in MPEG-compressed Video: Test Patterns and Metrics

January 1, 2000
Author(s)
Charles D. Fenimore, John M. Libert, Peter Roitman
Mosquito noise is a time dependent video compression impairment in which the high frequency spatial detail in video images having crisp edges is aliased intermittently. A new synthetic test pattern of moving spirals or circles is described which generates

Nanocomposites of Molecularly Dispersed Polyamidoamine (PAMAM) Dendrimers

January 1, 2000
Author(s)
G Kim, C L. Jackson, T J. Prosa, Da-Wei Liu, Barry J. Bauer
The preparation of PAMAM dendrimer nanocomposites in an IPN polymer matrix was investigated as a function of generation using transmission electron microscopy (TEM) and small angle X-ray scattering (SAXS). To obtain image contrast in TEM, sodium

Nanofabrication via Atom Optics

January 1, 2000
Author(s)
Jabez J. McClelland
A review is given of the field of nanofabrication via atom optics. Discussion is presented of the fundamentals of atom manipulation and atom optics, with emphasis on the aspects that are, or might be, useful for nanofabrication. The current status of

Nanoindentation of Polymers: Tip Shape Calibration and Uncertainty Issues

January 1, 2000
Author(s)
Mark R. VanLandingham, John S. Villarrubia, G Meyers
Indentation measurements made with atomic force microscopy (AFM) probes are relative measurements, largely due to the lack of information regarding the tip shape of the AFM probes. Also, current tip shape calibration procedures used in depth-sensing

Nanosecond Magnetization Reversal in High Coercivity Thin Films

January 1, 2000
Author(s)
N D. Rizzo, Thomas J. Silva, Anthony B. Kos
We used a wide-field Kerr microscope to measure magnetization reversal in high coercivity thin film media that were subjected to nanosecond field pulses. Coplanar waveguides were used as a field source. Two different samples of CoCr 10Ta 4 were measured

Networking of Welding Applications: A Tutorial - Knowing the Basics Behind Network Technology Will Help Users of Welding Equipment Identify Where Networks May Be Most Beneficial

January 1, 2000
Author(s)
William G. Rippey, James D. Gilsinn, L Flitter
This article describes the basics of network technology and how networks are being applied to commercial welding applications. The goal is to help non-computer-expert weld technology users to decide where products that use networks may be beneficial, and

New Developments in Deep Ultraviolet Laser Metrology for Photolithography

January 1, 2000
Author(s)
Marla L. Dowell, Christopher L. Cromer, Richard D. Jones, Darryl A. Keenan, Thomas Scott
Current and future laser measurement services at 157, 193, and 248 nm will be reviewed. Laser power and energy measurements at 193 nm will be presented, electrical calibration issues will be reviewed. We report an overall calibration uncertainty of laser

New Limit on the D Coefficient in Polarized Neutron Decay

January 1, 2000
Author(s)
L Lising, S R. Hwang, J M. Adams, T J. Bowles, M C. Browne, T E. Chupp, K A. Coulterpark, Maynard S. Dewey, S J. Freedman, B K. Fujikawa, A Garcia, G L. Greene, G L. Jones, Hans P. Mumm, Jeffrey S. Nico, J M. Richardson, R G. Robertson, W A. Teasdale, Alan K. Thompson, E G. Wasserman, Fred E. Wietfeldt, R C. Welsh, J F. Wilkerson
