Parameter Selection for Constrained Solutions to III-Posed Problems

January 1, 2000
Author(s)
Bert W. Rust
Many physical measurements are modeled by linear integral equations expressing each measurement as the sum of an instrumental smearing of the desired function and a random measuring error. Discretizing the integrals gives an ill-conditioned linear

PARCS - A Primary Atomic Reference Clock in Space

January 1, 2000
Author(s)
Thomas P. Heavner, Leo W. Hollberg, Steven R. Jefferts, D Meekhof, Thomas E. Parker, William D. Phillips, S L. Rolston, Neil Ashby, W Klipstein, L Maleki, D Seidel, R W. Thompson, L Young, R Vessot, E Mattison, A Demarchi

Performance Evaluation of a Parallel Cantilever Biaxial Micropositioning Stage

January 1, 2000
Author(s)
E Amatucci, Nicholas Dagalakis, John A. Kramar, Fredric Scire
The phenomenal growth of opto-electronic manufacturing and future applications in micro and nano manufacturing has raised the need for low-cost high performance micro-positioners. The National Institutes of Standards and Technology (NIST) Advanced

Phase Radiography with Neutrons

January 1, 2000
Author(s)
B E. Allman, P J. McMahon, K A. Nugent, D Paganin, David L. Jacobson, Muhammad D. Arif, S. A. Werner

Polymer Layered Silicate Nanocomposites: Thermal Stability of Organic Cationic Treatments

January 1, 2000
Author(s)
Jeffrey W. Gilman, A B. Morgan, Richard H. Harris Jr., Paul C. Trulove, H DeLong, T E. Sutto
Nanocomposites result from the combination of materials with different properties at the nanometer scale. Some examples of these include: polymers combined with layered-silicate, polymers combined with nano-silica, hybrid materials prepared by sol-gel

Polymer Network Structure of Bonding Resin By Fluorescence Microscopy

January 1, 2000
Author(s)
K Komatsu, E S. Wu, Francis W. Wang, K Nemoto
The adhesive strength of a composite resin to dentin is generally affected by the polymer network structure of a bonding resin that is previously applied to primed dentin. This study aimed to investigate the effect of the polymer network structure of a

Polymer-Surface Interactions in Nanofilled Polymers

January 1, 2000
Author(s)
Alamgir Karim, Jack F. Douglas
An understanding of the influence of polymer-surface interactions on the interfacial properties of nanoparticle fillers in polymer matrices is critical for applications of nanoparticle filled polymer materials. The infuence of nanoparticle-surace
