A Reliable Message Delivery Protocol for Mobile Agents

January 1, 2000
Author(s)
Mudumbai Ranganathan, M Bednarek, Douglas C. Montgomery
The abstractions and protocol mechanisms that form the basis for inter-agent communications can significantly impact the overall design and effectiveness of Mobile Agent systems. We present the design and performance analysis of a reliable communication

A Simplified Realization for the Gaussian Filter in Surface Metrology

January 1, 2000
Author(s)
Y B. Yuan, Theodore V. Vorburger, Jun-Feng Song, Thomas B. Renegar
A simplified realization for the Gaussian filter in surface metrology is presented in this paper. The sampling function sinu/u is used for simplifying the Gaussian function. According to the central limit theorem, when n approaches infinity, the function

A Spline Algorithm for Modeling Cutting Errors on Turning Centers

January 1, 2000
Author(s)
David E. Gilsinn, Herbert T. Bandy, Alice V. Ling
The precision of manufacturing using machine tools depends on the accuracy of the relative position of the cutting tool with respect to the workpiece. Kinematic modeling of machine tools is used to describe this relative position. This motion can be

A Standards Infrastructure for the Future

January 1, 2000
Author(s)
Belinda L. Collins
This paper presents several approaches for a global standards infrastructure, from the viewpoint of the United States, and from the National Institute of Standards and Technology (NIST) in particular. The U.S. system is explained in some detail - in part

A Temporal Imaging and Microscopy of Atoms

January 1, 2000
Author(s)
Y B. Ovchinnikov
A way of temporal imaging of neutral atoms by means of pulsed gradient light potentials is considered. The possibility of producing 2D and 3D images of an atomic sample with resolution of about 4 nm and magnification up to 10 4 10 5 is shown.

A to Z of Thermodynamics

January 1, 2000
Author(s)
Robert N. Goldberg
This is a book review of A to Z of Thermodynamics, by P. Perrot.

A Welding Cell With Its Own Web Site

January 1, 2000
Author(s)
Timothy P. Quinn
Communications technology is allowing welding engineers to interact in the operation of a welding cell from a distance, as if they were physically present. The remote engineer can look at the weld, watch the robot motion, read front panel displays and

Acceptor Doping of Barium Strontium Titanate and Magnesium Oxide Composites

January 1, 2000
Author(s)
J. Synowczynski, G. Dewing, Richard G. Geyer, John H. Grosvenor Jr
The microwave dielectric properties of bulk barium strontium titanate and magnesium oxide ceramic composites are measured with cylindrical mode-filtered cavity and dielectric sleeve resonator techniques. The cylindrical wall of the mode- filtered cavity
