Nanofriction: The Observation of Elastic Plowing

Author(s)
Z C. Ying, Stephen M. Hsu
Accurate friction measurement at nanoscale is critical in reliable device design. Literature papers have reported different friction values for the same...

The Effect of Plowing on Nanofriction

Author(s)
Stephen M. Hsu, Z C. Ying
Development of low friction surfaces has become an important issue for the development of reliable devices with moving components. The common way to measure...

Assessment of a 3D-Printed Aluminum Corrugated Feed Horn at 118.7503 GHz

Author(s)
Josh Gordon, David R. Novotny, Ronald C. Wittmann, Michael H. Francis, Jeffrey R. Guerrieri, Periasamy Lavanya, Albin Gasiewski
All-metal 3D printing is investigated as a viable option for millimeter wave applications. 3D printing is finding applications across many areas and may be a...

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...

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...

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...

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...
