Spectral Response Based Calibration Method of Tristimulus Colorimeters

December 1, 1998
Author(s)
George P. Eppeldauer
The accuracy of tristimulus colorimeters can be increased by using detector standards instead of traditional lamp standards for calibration. After high accuracy absolute spectral response determination of the color channels, spectral and amplitude

Spectroradiometric Detector Measurements: Part III--Infrared Detectors

December 1, 1998
Author(s)
Alan L. Migdall, George P. Eppeldauer
The National Institute of Standards and Technology (NIST) supplies calibrations of IR photodetector's spectral radiant power response from 1.8 υm to 20 υm. The spectral responsivity of a detector under test is determined by comparison to an absolute

Spectroscopy of 2-aminopurine: An MCSCF Study

December 1, 1998
Author(s)
E L. Rachofsky, J B. Ross, Morris Krauss, R Osman
2-aminopurine (2AP) is a highly fluorescent isomer of adenine that can be incorporated into DNA as a probe of structure, dynamics, and protein-DNA interactions. Interpretation of the fluorescence of 2AP in DNA requires a model of the electronic structure

Supercritical Fluids: Their Properties and Applications

December 1, 1998
Author(s)
Johanna Levelt Sengers
This introductory chapter is intended to acquaint the reader with the unusual properties of supercritical fluids, and with the ways these properties are exploited for a variety of applications in the chemical process industry. The presentation is closely

Thermal Lattice Boltzmann Models (TLBM) for Compressible Flows

December 1, 1998
Author(s)
G Vahala, P Pavlo, L Vahala, Nicos Martys
The progress and challenges in thermal lattice Boltzmann modeling are discussed. In particular, momentum and energy closures schemes are contrasted. Higher order symmetric (but no longer space filling) velocity lattices are constructed for both 2D and 3D
