Wind Effects on Flame Spread and Ember Spotting Near a Structure

Author(s)
Kathryn M. Butler, Erik L. Johnsson, Marco G. Fernandez, Mariusz Zarzecki, Glenn P. Forney, Eric Auth
In wildland-urban interface (WUI) fires, combustible materials pose a potential threat to contiguous or nearby structures. Flame spread and firebrand spotting

Full Disk Encryption: Bridging Theory and Practice

Author(s)
Louiza Khati, Nicky Mouha, Damien Vergnaud
We revisit the problem of Full Disk Encryption (FDE), which refers to the encryption of each sector of a disk volume. In the context of FDE, it is assumed that

Long-term instability in UTC time links

Author(s)
Victor S. Zhang, Demetrios Matsakis, Zhiheng Jiang
Calibration and link stability are the key issues for the UTC time transfer. This study is made in the framework of a joint task group of the CCTF Working Group

Local Distribution and Calibration of Timing Signals at NIST

Author(s)
Joshua J. Savory, Liz C. Forero, Kristopher Maurer, Stefania Romisch
The National Institute of Standards and Technology (NIST) timescale produces a real-time realization of UTC(NIST) in the form of a pulse-per-second (PPS) time

Accurate TWSTFT time transfer with indirect links

Author(s)
Victor S. Zhang, Zhiheng Jiang, Thomas E. Parker, Jian Yao, Yi-Jiun Huang, Shinn-Yan Lin
The conventional wisdom suggests a direct Two-Way Satellite Time and Frequency Transfer (TWSTFT or TW) time link should result in a smaller uncertainty than

A Clock Ensemble Using Only Active Hydrogen Masers

Author(s)
Thomas E. Parker, Stefania Romisch
The current real-time timescale at NIST, AT1, as well as the post-processed scale TP162, both contain hydrogen masers and commercial cesium frequency standards

Trapped-ion optical atomic clocks at the quantum limits

Author(s)
David R. Leibrandt, Samuel M. Brewer, Jwo-Sy Chen, Aaron M. Hankin, David B. Hume, David J. Wineland, Chin-Wen Chou
Frequency and its inverse, time, are the most accurately measured quantities. Historically, improvements in the accuracy of clocks have enabled advances in

2015 Location-Based Services R&D Summit Report

Author(s)
Harris Feldman, Adam H. Danielson
The Public Safety Communications Research Program (PSCR) convened over 80 stakeholders at the National Institute of Standards and Technology (NIST) Boulder, CO
