2016 PSCR Analytics Summit Report

January 30, 2017
Author(s)
Jeremy E. Benson, Harris Feldman
PSCR hosted over 80 stakeholders from industry, academia, public safety, and government to the NIST Boulder campus in August 2016. The August summit was a follow-up to the Public Safety Analytics R&D Roadmap, published earlier in 2016. This document

Foreword

Author(s)
Sokwoo Rhee
For IoT to be broadly adopted, it is important to apply the concept to many applications at scale in our everyday life. Using these advanced technologies, our communities and cities can be more intelligent, secure, and resilient. The Hardware and

Trapping States of Mixed-Isomer Organic Semiconductors within Organic Field-Effect Transistors

December 14, 2016
Author(s)
Peter Diemer, Jacori Hayes, Evan Welchman, Rawad Hallani, Sujitra Pookpanratana, Christina Hacker, Curt A. Richter, Timo Thonhauser, Oana Jurchescu
Organic field effect transistor (OFET) performance is dictated by the composition and geometry of the device, as well as the quality of the organic semiconductor (OSC) film, which strongly depends on the purity and structural defects. When present, these

BLER Performance Evaluation of LTE Device-to-Device Communications

November 9, 2016
Author(s)
Jian Wang, Richard A. Rouil
Long-Term Evolution (LTE) supporting Device-to-Device (D2D) communication is a feature introduced in 3rd Generation Partnership Project (3GPP) release 12. D2D communication is critical in public safety applications, which enables communication among first

Calibration of Time-interleaved Errors in Real-time Digital Oscilloscopes

November 1, 2016
Author(s)
Jeffrey A. Jargon, Chihyun Cho, Joo-Gwang Lee, Paul D. Hale, Peter J. Jeavons, John B. Schlager, Andrew M. Dienstfrey
A novel method is proposed for the calibration of channel mismatch in a time-interleaved real- time digital oscilloscope (RTDO). A simple simultaneous equation is derived from the Fourier transform of the time-interleaved signals requiring only a transfer

Model Verification with Measurement Uncertainty

November 1, 2016
Author(s)
Dylan F. Williams, Richard A. Chamberlin, Jerome G. Cheron, Wei Zhao, Urteaga Miguel
We verify a model for state-of-the-art 250 nm heterojunction bipolar transistors with large-signal measurements. We demonstrate the propagation of correlated measurement uncertainties through the model-extraction and verification process, and use them to

Giant surface conductivity enhancement in a carbon nanotube composite by ultraviolet light exposure

July 29, 2016
Author(s)
Christian J. Long, Nathan D. Orloff, Kevin A. Twedt, Thomas F. Lam, Luis Fernando Vargas Lara, Minhua Zhao, Bharath NMN Natarajan, Keana C. Scott, Eric Marksz, Tinh Nguyen, Jack F. Douglas, Jabez J. McClelland, Edward J. Garboczi, Jan Obrzut, James A. Liddle
Carbon nanotube composites are lightweight, multifunctional materials with readily adjustable mechanical and electrical properties—relevant to the aerospace, automotive, and sporting goods industries as high-performance building materials. Here, we combine

Insulator-quantum Hall transition in monolayer epitaxial graphene

July 22, 2016
Author(s)
Lung-I Huang, Yanfei Yang, Randolph Elmquist, Shun-Tsung Lo, Fan-Hung H. Liu, Chi-Te Laing
We report on magneto-transport measurements on low-density, large-area monolayer epitaxial graphene devices grown on SiC. We observe temperature (T)-independent crossing points in the longitudinal resistivity (rho)sub(xx), which are signatures of the
