Rotational Spectra, Conformational Structures and Dipole Moments of Thiodiglycol by Jet-Cooled FTMW and Ab Initio Calculations

May 1, 2004
Author(s)
L H. Xu, Q Liu, R D. Suenram, Francis J. Lovas, Angela R. Hight Walker, J O. Jensen, A C. Samuels
The rotational spectra of three low-energy conformers of thiodiglycol (TDG) (HOCH2CH2SCH2CH2OH) have been measured in a molecular beam using a pulsed-nozzle Fourier-transform microwave spectrometer. To determine the likely conformational structures with ab

Serial Correlation of QC Data on the Use of Proper Control Charts

May 1, 2004
Author(s)
P Winkel, Nien F. Zhang
Biochemical quality control data have been reported to be autocorrelated. Serial correlation may increase the rate of false alarms and decrease that of true alarms if traditional control charts are used. In this paper, the times series were examined and

Structural and Dynamic Heterogeneity in a Telechelic Polymer Solution

May 1, 2004
Author(s)
D Bedrov, G D. Smith, Jack F. Douglas
We utilize molecular dynamics simulations to investigate the implications of micelle formation on structural relaxation and polymer bead displacement dynamics in a model telechelic polymer solution. The transient structural heterogeneity associated with

Temporal Range Registration for Unmanned Ground and Aerial Vehicles

May 1, 2004
Author(s)
Rajmohan (. Madhavan, Tsai H. Hong, Elena R. Messina
An iterative temporal registration algorithm is presented in this paper1 for registering 3D range images obtained from unmanned ground and aerial vehicles traversing unstructured environments. We are primarily motivated by the development of 3D

Test Environment and Procedures for Testing EnCase 3.20

May 1, 2004
Author(s)
James R. Lyle
This document describes the testing of EnCase 3.20. The test cases that were applied are described in Disk Imaging Tool Specification, Version 3.1.6.The tests were run on test systems in the Computer Forensics Tool Testing Lab at the National Institute of

Test Environment and Procedures for Testing EnCase 3.20, Version 1.0

May 1, 2004
Author(s)
James R. Lyle
Our results extending Kuhn's fault class hierarchy provide a justification for the focus of fault-based testing strategies on detecting particular faults and ignoring others. We develop a novel analytical technique that allows us to elegantly prove that

The AMIS Approach to Systems Integration: An Overview

May 1, 2004
Author(s)
Donald E. Libes, Edward J. Barkmeyer Jr., Peter O. Denno, David Flater, Michelle P. Steves, Evan K. Wallace, Allison Barnard Feeney
This paper is an overview of the AMIS (Automated Methods for Integrating Systems) project approach to systems integration. The objective of the AMIS project is to reduce the cost and time for software integration by devising methods, algorithms, and tools

The Rheology of Cementitious Materials: Chemistry, Colloids and Rocks

May 1, 2004
Author(s)
Robert J. Flatt, Nicos Martys
Knowledge of colloidal science has proven essential in the development of a new generation of dispersants for concrete. These polymer molecules induce steric repulsion between cement particles, reducing agglomeration and allow high workability to be

Thermal and Flammability Properties of Polypropylene/Carbon Nanotube Nanocomposites

May 1, 2004
Author(s)
Takashi Kashiwagi, E A. Grulke, J N. Hilding, Richard H. Harris Jr., John R. Shields, Kathryn M. Butler, K M. Groth, S B. Kharchenko, Jack F. Douglas
The thermal and flammability properties of polypropylene/multi-walled carbon nanotube, (PP/MWNT) nanocomposites were measured with the MWNT content varied from 0.5 % to 4 % by mass. Dispersion of MWNTs in these nanocomposites was characterized by SEM and

Ti ls Pre-Edge Features in Rutile: A Bethe-Salpeter Calculation

May 1, 2004
Author(s)
Eric L. Shirley
This work studies Ti K-edge excitation in rutile TiO2 by considering the x-ray absorption spectrum in a Bethe-Salpeter approach. This work compares resultes obtained by experiment and previous theoretical results obtain within the Anderson impurity model

Tuning Spectral Properties of Fullerenes by Substitutional Doping

May 1, 2004
Author(s)
Rui-Hua Xie, Garnett W. Bryant, G Sun, T Kar, Z Chen, V H. Smith, Y Araki, N Tagmatarchis, H Shinohara, O Ito
We propose a substitutional doping approach to achieve tunable optical properties from fullerenes. Taking Cd60 as an example and using time-dependent density functional theory, we compute the absorption spectra of heterofullerenes Cd60-dn-dm-NdnBdm, and
