A Parallel 3D Dendritic Growth Simulator using the Phase-Field Method

January 1, 2002
Author(s)
William L. George, James A. Warren
We describe an implementation of a parallel finite-difference algorithm for the simulation of alloy solidification in three dimensions using the phase-field model. We also describe the visualization of the output from this simulator. Although thistype of

A Phase Diagram for the Bose-Einstein Condensation of Magnons

January 1, 2002
Author(s)
Lawrence H. Bennett, Edward Della Torre, Philip Johnson, R E. Watson
We have recently identified evidence of the Bose-Einstein condensation (BEC) of magnons in nanostructures. This behavior occurs for nanoparticles some 10s of nms in size (having some millions of atoms in a nanoparticle). Here we explore the effect of

A Phase-Field Model of Convection with Solidification

January 1, 2002
Author(s)
D M. Anderson, Geoffrey B. McFadden, A A. Wheeler
A phase-field model for the solidification of a pure material that incorporates convection has recently been developed. This model is a two-fluid model in which the solid phase is modeled as a sufficiently viscous fluid. The model allows for the solid and

A Weekly Cycle in Atmospheric Carbon Dioxide

January 1, 2002
Author(s)
R S. Cerveny, Kevin Coakley
We present a new statistic called the Mean Symmetrized Residual (MSR) for detection and quantification of a weekly cycle in measured daily atmospheric carbon dioxide (CO 2). At the Mauna Loa Observatory in Hawaii, we conclude that CO 2 concentrations, on

Accelerated Wear Tests for the Assessment of Machining Models Calibration Data

January 1, 2002
Author(s)
Robert W. Ivester, Michael Kennedy
This paper documents the release of the accelerated wear tests for the Assessment of Machining Models (AMM) calibration data set, including a minimum of background material, a summary of previously published results, and plans for the remainder of the AMM
