Pixel Based Absolute Topography Test for Three Flats

January 1, 1998
Author(s)
R E. Parks, Lianzhen Shao, Christopher J. Evans
We demonstrate a new method of performing the absolute three flat test using reflection symmetries of the surfaces and an algorithm for generating the rotation of arrays of pixel data. Most of the operations involve left/right and top/bottom flips of data

Polarized Light Emission from the Metal-Metal STM Junction

January 1, 1998
Author(s)
Daniel T. Pierce, Angela Davies, Joseph A. Stroscio, Robert Celotta
The polarization of light emitted during inelastic tunneling of electrons into both Au(111) and Fe(001) using W(111) tips in an STM junction has been fully characterized by measuring the Stokes parameters. The emitted light for both Au(111) and Fe(001) is

Leslie E. Smith, B M. Fanconi
Technical activities of the Polymers Division, 854, for the 1997 fiscal year are described. The report is organized by programs: Electronic Interconnection and Assembly; Polymer Blends and Processing, Polymer Composites, Polymer Characterization, Dental

Post-Installed Anchors. A Literature Review

January 1, 1998
Author(s)
Geraldine S. Cheok, Long T. Phan
A literature review of studies on the behavior of post-installed concrete anchors is presented. The survey covers several types of anchors that are subjected to tension loads, shear loads, and to combined shear and tension loads. Brief summaries of the

Proceedings of the 1997 Knowledge-Based Systems Interoperability Workshop

January 1, 1998
Author(s)
Robert Allen
The proceedings provides the background, goals, activities, and results of a National Institute of Standards and Technology-sponsored workshop on Knowledge- Based Systems Interoperability (KBSI). Twenty-four participants shared ideas, identified issues and

Process Effects on White Layer Formation in Hard Turning

January 1, 1998
Author(s)
Y K. Chou, Christopher J. Evans
This paper discusses surface microstructural alterations in hard turned steels. A metallurgically unetchable structure, called white layer?, followed by a dark etching layer has been found on AISI 52100 steel surfaces machined in a hardened state (60 Rc)
