Calibration and Characterization of UV Sensors for Water Disinfection

January 2, 2006
Author(s)
Thomas C. Larason, Yoshihiro Ohno
Ultraviolet radiation (UV) effectively inactivates common pathogens found in ground and surface waters such as Cryptosporidium, Giardia, and most bacterial pathogens (e. g., E. coli). Water treatment facilities recently started using ultraviolet radiation

Field Dependence of the Barrier to Magnetization Reversal of a Stoner-Wohlfarth Particle

January 2, 2006
Author(s)
Edward Della Torre, Lawrence H. Bennett, G Kahler, Roland deWit, R E. Watson
The energy barrier for magnetization reversal, E(sub B), varies quadratically with magnetic field, as is well known. Nonetheless, the energy (enthalpy) required to reverse the magnetization involves E(sub B) plus the work associated with the magnetic field

Microwave Spectrum and Structure of Methyl Phosphonic Difluoride

January 2, 2006
Author(s)
R D. Suenram, Francis J. Lovas, David F. Plusquellic, M W. Elizy, J M. Lochner, J O. Jensen, A C. Samuels
The rotational spectrum of methyl phosphonic difluoride has been reinvestigated using a pulsed-molecular-beam Fabry-Perot cavity microwave spectrometer. The enhanced resolution of the Fourier transform microwave (FTMW) spectrometer (compared to the

Phase-Field Modeling of Solidification Under Stress

January 2, 2006
Author(s)
Julia Slutsker, K Thornton, Alexander Roytburd, James A. Warren, Geoffrey B. McFadden, P W. Voorhees
A phase-field model that includes the stress field during non-isothermal phase transformation of a single-vomponent system has been developed. The model has been applied to the solidification and melting of confined spherical volumes, where sharp interface

Standard Measurement Methods for Materials Properties: Plasticity

January 2, 2006
Author(s)
Richard J. Fields, Sheldon M. Wiederhorn
Plasticity, or permanent deformation, is one of the most useful mechanical properties of materials. It permits forming of parts, and provides a significant degree of safety in use. The ability to specify plastic properties measured by the standard methods

A Flexible System Framework for a Nanoassembly Cell Using Optical Tweezers

January 1, 2006
Author(s)
Arvind K. Balijepalli, Thomas W. LeBrun, Satyandra K. Gupta
The optical tweezers instrument is a unique tool for directed assembly of nanocomponents. In order to function as a viable nanomanufacturing tool, a software architecture is needed to run the optical tweezers hardware, provide an effective user interface

A Measurement-Based Multisine Design Procedure

January 1, 2006
Author(s)
M. Myslinski, Kate Remley, Michael McKinley, Dominique Schreurs, Bart Nauwelaers
This work presents a procedure to design a multisine with probability density function (PDF) similar to that of a measured realistic digitally modulated signal. We discuss important practical issues crucial to the successful multisine construction and
