Limiting The Impact of Stealthy Attacks on Industrial Control Systems

October 28, 2016
Author(s)
David Urbina, Alvaro Cardenas, Niles O. Tippenhauer, Junia Valente, Mustafa Faisal, Justin Ruths, Rick Candell, Heinrik Sandberg
While attacks on information systems have for most practical purposes binary outcomes information was manipulated/eavesdropped, or not), attacks manipulating the sensor or control signals of Industrial Control Systems (ICS) can be tuned by the attacker to

Modulus--Pressure Equation for Confined Fluids

October 28, 2016
Author(s)
Daniel W. Siderius, Gennady Y. Gor, Vincent K. Shen, Noam Bernstein
Ultrasonic experiments allow one to measure the elastic modulus of bulk solid or fluid samples. Recently such experiments have been carried out on fluid-saturated nanoporous glass to probe the modulus of a confined fluid. In our previous work (J. Chem

Video Analytics at the Edge

October 28, 2016
Author(s)
John S. Garofolo
This is a slide for an invited panel talk at the First IEEE/ACM Symposium on Edge Computing on the need for research in edge computing and future standards related to video analytics in safety and security video network domains such as public safety.

Revised and extended analysis of the eighth spectrum of platinum (Pt VIII)

October 27, 2016
Author(s)
Vladimir I. Azarov, R R. Gayasov
The spectrum of platinum was observed in the (300-2100) Å wavelength region. Grazing and normal incidence VUV spectrographs have been used to record the spectrum. The (5d3 + 5d26s) - 5d26p transition array of seven times ionized platinum, Pt VIII, has been

Thermodynamic Properties at Saturation Derived from Experimental Two-Phase Isochoric Heat Capacity of 1-Hexyl-3-methylimidazolium bis[trifluoromethyl)sulfonyl]imide

October 27, 2016
Author(s)
Joe W. Magee, N. G. Polikhronidi, Rabiyat G. Batyrova, I M. Abdulagatov, J. Wu
New measurements are reported for the isochoric heat capacity of the ionic liquid substance 1- hexyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide ([C6mim][NTf2]). These measurements extend the ranges of our earlier study [N.G. Polikhronidi et al

Comprehensive Assessment of Composition and Thermochemical Variability of Three Prototype Gas Turbine Fuels by GC/QToF-MS and the Advanced Distillation-Curve Method as a Basis of Comparison for Novel Fuel Development

October 26, 2016
Author(s)
Tara Lovestead, Jessica L. Burger, Nico Schneider, Thomas J. Bruno
Commercial and military aviation is faced with challenges that include high fuel costs, emissions, and supply chain security that result from the reliance on petroleum-based feedstocks. The development of alternative gas turbine fuels from renewable

Secure and usable enterprise authentication: Lessons from the Field

October 26, 2016
Author(s)
Mary F. Theofanos, Simson L. Garfinkel, Yee-Yin Choong
There are now more than 5.4 million Personal Identity Verification (PIV) and Common Access Card (CAC) identity cards deployed to US government employees and contractors. These cards are widely used to gain physical access to federal facilities, but their

Gas Uptake of 3-D Printed Acrylonitrile Butadiene Styrene (ABS) Using a Vacuum Apparatus Designed for Absorption and Desorption Studies

October 25, 2016
Author(s)
Makfir Sefa, Zeeshan Ahmed, James A. Fedchak, Nikolai Klimov, Julia Scherschligt
We describe a vacuum apparatus for determining the outgassing rate into vacuum, the diffusion coefficient, and the amount of gas absorbed for various materials. The diffusion coefficient is determined from a model applied to time-dependent desorption data

Validating In-Air Remote Sensing Reflectance Measurements During Cruises Using Reflectance Targets

October 25, 2016
Author(s)
Bettye C. Johnson, Catherine C. Cooksey, Ahmed El-Habashi, David English, Georgi T. Georgiev, Sherwin Ladner, Veronica P. Lance, Michael Ondrusek, Ryan Vandermeulen
Annual dedicated ocean color validation cruises off the East Coast of the USA were started in November 2014 with support from the NOAA office of Marine and Air Operations with primary focus on VIIRS/SNPP and upcoming JPSS missions. A portion of the

Making Email Trustworthy

October 24, 2016
Author(s)
Scott W. Rose, Larry Feldman, Gregory A. Witte
This bulletin summarizes the information presented in NIST SP 800-177: Trustworthy Email. This publication gives recommendations and guidelines for enhancing trust in email. This guideline applies to federal IT systems and will also be useful for any small

Measuring Temperature in Emission Testing Micro-chambers

October 24, 2016
Author(s)
Dustin G. Poppendieck, Edwin Guillermo, Havishk Tripathi
ASTM subcommittee D22.05 on Indoor Air is working to finalize WK40293: Standard Test Method for Estimating Chemical Emissions from Spray Polyurethane Foam (SPF) Insulation Using Micro-Scale Environmental Test Chambers. One issue in WK40293 is determining

Nanoscale Pillar-enhanced Tribological Surfaces as Antifouling Membranes

October 24, 2016
Author(s)
Edwin P. Chan, Wansuk Choi, Won-Gi Ahn, Jong-Hyun Park, Hyun W. Jung, Seungkwan Hong, Ji-Young Han, Sangpil Park, Doo-Hyun Ko, Jung-Hyun Lee
We present a nonconventional membrane surface modification approach that utilizes surface topography to manipulate the tribology of foulant accumulation on water desalination membranes via imprinting of submicron titanium dioxide (TiO2) pillar patterns

A Few Selected Contributions to electron and photon collisions with H_2+ and H_2

October 23, 2016
Author(s)
Barry I. Schneider, Lee A. Collins, klaus Bartschat, Xiaoxu Guan, Suxing Hu
We discuss a number of aspects regarding the physics of H_2+ nd H_2. This includes low-energy electron scattering processes and the interaction of both weak (perturbative) and strong (ultrafast/intense) electromagnetic radiation with those systems.

The Role of Measurement Uncertainty in Achieving First-Pass Design Success

October 22, 2016
Author(s)
Dylan Williams, Richard Chamberlin, Wei Zhao, Jerome Cheron, Urteaga Miguel
We investigate the role of measurement uncertainty in achieving first-pass design success at microwave frequencies. We develop a model for state-of-the-art 250 nm heterojunction bipolar transistors, and demonstrate the propagation of correlated measurement
