New Standard Provides Framework for Smart Grid Testing and Certification

July 31, 2016
Author(s)
Cuong T. Nguyen, Khaled Masri
In May 2016, the National Electrical Manufacturers Association (NEMA) published a new standard, Smart Grid Interoperability Process Reference Manual, ANSI/NEMA SG-IPRM 1-2016 (IPRM). The standard codifies a 40-page publication, the Interoperability Process

Color Quality Metrics Recent Progress and Future Perspective

July 30, 2016
Author(s)
Yoshihiro Ohno
The color quality of light sources for lighting includes the effects of white light chromaticity, as well as color rendition characteristics, including color fidelity and the aspects related to color preference and perception. In this paper, the current

Cryogenic Etching of High Aspect Ratio 400 nm Pitch Silicon Gratings

July 29, 2016
Author(s)
Houxun Miao, Lei Chen, Mona Mirzaeimoghri, Richard Kasica, Han Wen
The cryogenic process and Bosch process are two widely used processes for reactive ion etching of high aspect ratio silicon structures. This paper focuses on the cryogenic deep etching of 400.0 nm pitch silicon gratings. By creating a metal hard mask on

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

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

Sisyphus Thermalization of Photons in a Double Quantum Dot

July 29, 2016
Author(s)
Michael Gullans, J. Stehlik, Y.-Y. Liu, Christopher Eichler, Jason Petta, Jacob M. Taylor
A strongly driven quantum system coupled to a thermalizing bath generically evolves into a highly non-thermal state as the external drive competes with the equilibrating force of the bath. We demonstrate a notable exception to this picture for a microwave

User's Guide to Telework and Bring Your Own Device (BYOD) Security

July 29, 2016
Author(s)
Murugiah P. Souppaya, Karen Scarfone
Many people telework, and they use a variety of devices, such as desktop and laptop computers, smartphones, and tablets, to read and send email, access websites, review and edit documents, and perform many other tasks. Each telework device is controlled by

Dynamic Metrology and ASTM E57.02 Dynamic Measurement Standard

July 28, 2016
Author(s)
Roger V. Bostelman, Tsai H. Hong, Mili Shah, Steven Legowik
Optical tracking systems are used in a wide range of fields. The market for optical tracking systems has dramatically increased over the past several years to $1.2B revenue in 2014. This paper describes the new ASTM E3064 Standard test method procedures

Networks of 'Things'

July 28, 2016
Author(s)
Jeffrey M. Voas
System primitives allow formalisms, reasoning, simulations, and reliability and security risk-tradeoffs to be formulated and argued. In this work, five core primitives belonging to most distributed systems are presented. These primitives apply well to

Quasiparticle Lifetime Broadening in Resonant X-ray Scattering of Ammonium Nitrate

July 28, 2016
Author(s)
John Vinson, Terrence J. Jach, Matthias Mueller, Rainer Unterumsberger, Burkhard Beckhoff
It has been previously shown that two effects cause dramatic changes in the x-ray absorption and emission spectrra from the N K edge of the insulating crystal ammonium nitate. First, vibrational disorder causes major changes in the absorption spectrum

Self-terminated Electrodeposition of Ni, Co and Fe Ultrathin Films

July 28, 2016
Author(s)
Thomas P. Moffat
Self-terminated iron group metal electrodeposition occurs at potentials negative of the onset of water reduction due to formation of a monolayer thick hydroxide layer. Quenching of metal deposition is accompanied by an increase in dissipative energy loss

Cure temperature influences electrical properties via carbon nanotube-rich domain formation

July 27, 2016
Author(s)
Chelsea S. Davis, Nathan D. Orloff, Jeremiah W. Woodcock, Christian J. Long, Kevin A. Twedt, Bharath NMN Natarajan, Jonathan E. Seppala, Jabez J. McClelland, Jan Obrzut, James A. Liddle, Jeffrey W. Gilman
Carbon nanotube (CNT) nanocomposites are enticing materials that enable engineers to tailor structural and electrical properties for applications in the automotive and aerospace industries. CNT mass fraction and the matrix cure temperature are two ways to

Direct Measurements of 3D Structure, Chemistry, and Mass Density During the Induction Period of C3S Hydration

July 27, 2016
Author(s)
Qinang Hu, Mohammed Aboustait, Taehwan Kim, Tyler Ley, Jeffrey W. Bullard, Jay C. Hanan, Volker Rose, Robert Winarski
The reasons for the start and end of the induction period remain a mystery in cement hydration. One long-standing hypothesis is the importance of early hydration products on the surface of cement particles. However, because this material is not widely
