Modeling of moment connections for structural fire analyses

January 5, 2016
Author(s)
Mina S. Seif, Therese P. McAllister, Joseph A. Main, William E. Luecke
Performance-based methodologies to evaluate the fire performance of structures are needed to move beyond the prescriptive procedures presently in use, which cannot be used to determine actual structural performance in fire. Analytical methods are needed

Spectrum and Energy Levels of Five-Times Ionized Zirconium (Zr VI)

January 5, 2016
Author(s)
Joseph Reader, Mark D. Lindsay
The spectrum of five-times-ionized zirconium Zr VI was observed from 160 Å to 2000 Å with sliding spark discharges on 10.7-m normal- and grazing-incidence spectrographs. The existing analysis of this spectrum [Khan Z. A. et al. 1985 Phys. Scr. 31 837] was

Spectrum Sensing with WLAN Access Points

January 5, 2016
Author(s)
Jason Coder, Ryan T. Jacobs, Vivian Musser
With wireless communication becoming more and more common in simple everyday devices, the available spectrum is quickly filling up and the risk of interference is increasing. This interference could be a slight nuisance to or it could be a more significant

Testing Spectrum Sensing Networks by UAV

January 5, 2016
Author(s)
Dan Kuester, Ryan T. Jacobs, Yao Ma, Jason Coder
We consider here the use of hovering unmanned aerial vehicles (UAVs) to test spectrum sensing capabilities of Citizen's Broadband Radio Service (CBRS) systems at 3.5 GHz. Aircraft transmit synthesized LTE or pulsed radar modulation to excite spectrum

Flexible Lines with Setups: Analysis, Improvement, and Application

January 4, 2016
Author(s)
Cong Zhao, Jingshan Li, Ningjian Huang, John A. Horst
Setup times commonly exist in many flexible manufacturing lines to adjust tools and carry out safety and quality checks during product changeovers. In this paper, a Markov chain model is introduced to study flexible manufacturing lines with setups. An

Advances in Thermometry

January 1, 2016
Author(s)
Michael R. Moldover, Weston L. Tew, Howard W. Yoon
The last 25 years have seen tremendous progress in thermometry in the moderate temperature range (1 K to 1235 K). Various primary thermometers — based on different physics —have uncovered errors in the International Temperature Scale of 1990 and set the

An Effective Video Synopsis Approach with Seam Carving

January 1, 2016
Author(s)
Hamid Gharavi
With a growth of surveillance cameras, the amount of captured videos expands. Manually analyzing and retrieving surveillance video is labor intensive and expensive. It would be much more convenient to generate a video digest, with which we can view the

ASTM Workshop on Standards & Measurements for Tissue Engineering Scaffolds

January 1, 2016
Author(s)
Carl G. Simon Jr., John Test, Michael Yaszemski, Reto Luginbuehl, Anthony Ratcliffe, Paul Tomlins
A “Workshop on Standards & Measurements for Tissue Engineering Scaffolds” was held on May 21, 2013 and was sponsored by the American Society of Testing and Materials International (ASTM International) in Indianapolis, IN. The purpose of the workshop was to

Chapter 154. Choline | Properties and Determination

January 1, 2016
Author(s)
Melissa M. Phillips
Choline is an essential nutrient that is required for normal cell function, with involvement in numerous cellular processes. Choline can be produced via de novo biosynthesis, but must be complimented with dietary intake to support optimum health. Foods

Cyber-Physical Social Systems: Getting People into the Loop

January 1, 2016
Author(s)
Sulayman Sowe, Eric D. Simmon, Koji Zettsu, Frederic J. de Vaulx, Irena Bojanova
This paper outlines the need to effectively integrate people into the design of a new generation of Cyber-Physical Social Systems (CPSS) and proposes a Human Service Capability Description Model to do it.

Density measurements of compressed-liquid dimethyl ether + pentane mixtures

January 1, 2016
Author(s)
Stephanie L. Outcalt, Eric W. Lemmon
Compressed-liquid densities of three compositions of the binary mixture dimethyl ether (CAS No. 115-10-6) + pentane (CAS No. 109-66-0) have been measured with a vibrating U-tube densimeter. Measurements were made at temperatures from 270 K to 390 K with

Design of a breast phantom for quantitative MRI

January 1, 2016
Author(s)
Kathryn E. Keenan, Sheye O. Aliu, Lisa J. Wilmes, David C. Newitt, Ella F. Jones, Wen Li, Michael A. Boss, Nola M. Hylton
Purpose: We present a breast phantom designed to enable quantitative assessment of measurements of T 1 relaxation time, apparent diffusion coefficient (ADC), and other attributes of breast tissue, with long-term support from a national metrology institute

Growth of one-dimensional nanomaterials in the ETEM

January 1, 2016
Author(s)
Jonathan P. Winterstein, Renu Sharma
One-dimensional nanomaterials (nanowires and nanotubes) have a number of unique and interesting properties that have made them the subject of significant research for a wide range of applications. Electron microscopy is generally necessary for their
