Assessment of Machining Models: Progress Report

January 1, 2000
Author(s)
Robert W. Ivester, Michael Kennedy, Matthew A. Davies, R Stevenson, J Thiele, R Furness, S M. Athavale
Machining involves extremely localized and nonlinear physical phenomena that occur over a wide range of temperatures, pressures, and strains. This has hindered progress in predictive modeling of machining processes. Many different types of models ranging

Assignment of Enzyme Substrate Specificity by Principal Component Analysis of Aligned Protein Sequences: An Experimental Test Using DNA Glycosylase Homologues

January 1, 2000
Author(s)
A Gogos, D Jantz, K. J. Tuerk, D Richardson, M. Dizdaroglu, N D. Clarke
We have studied the relationship between amino acid sequence and substrate specificity in a DNA glycosylase family by characterizing experimentally the specificity of four new members of the family. We show that principal component analysis (PCA) of the

Automatic Language Model Adapation for Spoken Document Retrieval

January 1, 2000
Author(s)
C G. Auzanne, John S. Garofolo, Jonathan G. Fiscus, W M. Fisher
This paper describes experiments implemented at NIST in adapting language models over time to improve recognition of broadcast news recorded over many months. These experiments were designed specifically to improve the utility of automatically generated

Blends of Fatty-Acid-Modified Dendrimers With Polyolefins

January 1, 2000
Author(s)
Barry J. Bauer, A Ramzi, D W. Liu, R L. Scherrenberg, P Froehling, J Joosten
Blends were made by solution and melt mixing fatty acid modified dendrimers with various polyolefins. Small angle neutron scattering (SANS) was used to determine the miscibility of the blends. Poly propylene imine (PPI) dendrimers G1, G3, and G5 (DAB-dendr
