Author(s)
Jin Liu, Kumarasiri Konthasinghe, Marcelo I. Davanco, John Lawall, Vikas Anant, Varun Verma, Richard Mirin, Jin Dong Song, Ben Ma, Ze Sheng Chen, Hai Qiao Ni, Zhi Chuan Niu, Kartik Srinivasan
Single self-assembled InAs/GaAs quantum dots are a promising solid-state quantum technology, with vacuum Rabi splitting, single-photon-level nonlinearities, and bright, pure, and indistinguishable single-photon generation having been demonstrated. In such

Calibration of Dynamic Pressure in a Tubing System and Optimized Design of Tube Configuration: A Numerical and Experimental Study

June 12, 2018

Matthew Kovaerk, Luke Amatucci, Keith A. Gillis, Florian Potra, James Ratino, Marc L. Levitan, DongHun Yeo
Accurate prediction of aerodynamic pressures on a building is a key factor in the estimation of wind loads on the building. Since the analytical approach has limited capacity in providing pressure estimates, wind tunnel testing is widely used. The

Dimensioning Wireless Use Cases in Industrial Internet of Things

June 12, 2018
Author(s)
Yongkang Liu, Rick Candell, Mohamed Hany, Lotfi Benmohamed
Industrial wireless is becoming increasingly needed in the Industrial Internet of Things (IIoT) for carrying mission-critical data to leverage the visibility, control, and safety of industrial environments. In this paper we propose a framework that

Dynamic Production System Identification for Smart Manufacturing Systems

June 12, 2018
Author(s)
Peter O. Denno
Knowledge of process requirements, system capacities, and system reliability are the premises on which control policies are formulated. In dynamic manufacturing environments, engineering change to the product, the process, and the production equipment can

Quantum Probability Estimation for Randomness with Quantum Side Information

June 12, 2018
Author(s)
Emanuel H. Knill, yanbao zhang, Honghao Fu
We develop a quantum version of the probability estimation framework [arXiv:1709.06159] for randomness generation with quantum side information. We show that most of the properties of probability estimation hold for quantum probability estimation (QPE)

On October 17, 2017, the ODI sponsored a day-long Standard Reference Data Workshop. More than 120 NIST staff members and associates from four NIST laboratories and three offices registered for this workshop. The workshop format consisted of presentations

Correlation of Neutron-Based Strain Imaging and Mechanical Behavior of Armor Steel Welds Produced with the Hybrid Laser Arc Welding Process

June 11, 2018
Author(s)
Jeffrey W. Sowards, Daniel S. Hussey, David L. Jacobson, Stan Ream, Paul A. Williams
Bragg edge neutron transmission imaging was used to characterize the spatial distribution of thermally induced residual strains in a steel armor plate welded with a hybrid laser arc process. This residual strain distribution was compared to the spatial
