Rabi Oscillations in a Large Josephson Junction Qubit

September 9, 2002
Author(s)
John M. Martinis, Sae Woo Nam, Joe Aumentado, C Urbina
We have designed and operated a circuit based on a large-area current-biased Josephson junction whose two lower energy quantum levels could be used to implement a solid-state qubit. The circuit allows measurement of the qubit states with a fidelity of 85%

Interface-Driven Model-Based Generation of Java Test Drivers

September 3, 2002
Author(s)
Mark Blackburn, Robert Busser, Aaron Nauman, Ramaswamy Chandramouli
This paper extends prior work in model-based verification and describes interface-driven analysis that combines with a requirement model to support automated generation of Java test scripts. It describes concepts of models and test driver mappings using

Test Procedures for Electric Motors Test Under 10 CFR Part 431

September 3, 2002
Author(s)
Ken L. Stricklett, M Vangel
The procedures for electric motor efficiency testing promulgated by Part 431 of Chapter II of Title 10, Code of Federal Regulations are discussed. The operating characteristics of the sampling plans for certification and enforcement testing are presented

A New Classification of Information: A Step on the Road to Interpretability

September 1, 2002
Author(s)
Larry H. Reeker, Albert W. Jones
Complex systems, such as manufacturing supply chains, are often modeled as a collection of interacting components with information flows between them. These components are frequently responsible for making a wide range of decisions that are implemented

Accuracy of AlGaAs Rates and Composition Determination Using RHEED Oscillations

September 1, 2002
Author(s)
Todd E. Harvey, Kristine A. Bertness, Chih-Ming Wang, Jolene Splett
Reflection high-energy electron diffraction (RHEED) oscillations are widely used in molecular beam epitaxy (MBE) as a technique to calibrate material growth rates. The growth rates are used to predict the composition of the following growth run. For many

Acoustic Spectroscopy of Lithium Niobate: Elastic and Piezoelectric Coefficient

September 1, 2002
Author(s)
H Ogi, Y Kawashima, M Hirao, H M. Ledbetter
We report the first Simultaneous measurement of a crystal's complete elastic and piezoelectric coefficients: C if, e ijk. The studied crystal was lithium niobate (LiNbO 3) with trigonal crystal symmetry (3 m point group), thus six independent C ijk, four e

Adaptive Control of a Construction Manipulator

September 1, 2002
Author(s)
V Gradetsky, M Rachkov, M Pushkin
The paper describes an advanced control technique that uses a self-adjusting controller. The technique allows changing control parameters of the manipulator according to different technological forces and disturbances acting to the end-effector of the

Algal Rhodopsins: Phototaxis Receptors Found at Last

September 1, 2002
Author(s)
K D. Ridge
The discovery of two distinct Chlamydomonas sensory receptors responsible for phototaxis reveals additional diversity among the microbial rhodopsins. Sequence and architecture comparisons among this growing family highlight key components for light

An Improved Nonlinear Optical Pulse Propagation Equation

September 1, 2002
Author(s)
M Trippenbach, W Wasilewski, P Kruk, Garnett W. Bryant, G Fibich, Y B. Band
A new equation for self-focusing of extremely focused short-duration intense pulses is derived. This method can yield results to all orders of diffraction and dispersion with nonlinearity present, including the self-consistent derivation of nonlinear

Analysis of Kaolinite/Chrysotile Mixtures by Ashing and X-Ray Diffraction

September 1, 2002
Author(s)
Jennifer R. Verkouteren, Eric S. Windsor, Joseph M. Conny, R L. Perkins, J T. Ennis
A simple ashing procedure is described that converts kaolinite to amorphous metakaolinite while retaining the diffraction intensity of chrysotile. This ashing procedure removes the XRD pattern overlap between kaolinite and chrysotile that can interfere

Analysis of Switching in Uniformly Magnetized Bodies

September 1, 2002
Author(s)
Michael J. Donahue, Donald G. Porter
A full analysis of magnetization reversal of a uniformly magnetized particle by coherent rotation is presented.The magnetization energy of the particle in the presence of an applied field H is modeled as E = ( 0/2)MT DM - 0HTM.This model includes shape

Anomalously Large Intermixing in Aluminium-Transition Metal Bilayers

September 1, 2002
Author(s)
J D. Buchanan, T P. Hase, B K. Tanner, P J. Chen, L Gan, Cedric J. Powell, William F. Egelhoff Jr.
The interdiffusion lengths in thin film samples of the form X/Al and Al/X, where X is a metal from rows 4,5 and 6 of the Periodic Table, have been measured by Grazing Incidence X-ray Scattering. Scans of the specular reflectivity have been fitted to

Architecture and Implementation of a Design Repository System

September 1, 2002
Author(s)
Simon Szykman
This paper describes the design and development of a design repository software system. This system is a prototype implementation intended to demonstrate the role of design repositories as part of a vision for the next generation of product development
