Cross-Property Correlations and Permeability Estimation in Sandstone

October 26, 2005
Author(s)
C H. Arns, M A. Knackstedt, Nicos Martys
Results from a numerical study examining the cross-property correlations linking fluid permeability to conductive properties and to a number of pore size parameters based on 3D digitized images of sedimentary rock are presented. In particular we focus on

Time Synchronized Measurements in Cluster Computing Systems

August 1, 2000
Author(s)
Alan Mink, Robert J. Carpenter, M M. Courson
We describe hardware time synchronization instrumentation that we have developed which achieves time synchronization of better than one microsecond. The purpose of this instrumentation is for Quality of Service characterization of parallel and distributed

A Versatile Technique to Enable Sub-Milli-Kelvin Instrument Stability for Precise Radial Velocity Measurements: Tests with the Habitable-Zone Planet Finder

December 16, 2016

Ryan C. Terrien, Guomundur K. Stefansson, Fred Hearty, Paul Robertson, Suvrath Mahadevan, Tyler Anderson, Chad Bender, Matthew Nelson, Andrew Monson, Basil Blank, Samuel Halverson, Chuck Henderson, Lawrence Ramsey, Arpita Roy, Christian Schwab
Insufficient instrument thermo-mechanical stability is one of the fundamental roadblocks for achieving 10 cm s −1 Doppler radial velocity (RV) precision, the precision needed to detect Earth-twins orbiting Solar-type stars. Exquisite temperature and

New Calcium Tantalate Polytypes in the System Ca 2 Ta 2 O 7 - Sm 2 Ti 2 O 7

February 1, 2000
Author(s)
I E. Grey, Robert S. Roth
New calcium tantalate polytypes, with weberite related structures have been prepared by doping Ca 2Ta 2O 7 with Sm 2Ti 2O 7. Trigonal 6-layer (6T) and monoclinic 5-layer (5M) polytypes containing approximately equal to} 6 mol % and 10 mol % respectively of
