Relationship Between Quantitative Dispersion and Physical Properties of PMMA/SWNT Nanocomposites

February 19, 2017
Author(s)
Takashi Kashiwagi, Jeffrey Fagan, Keith Yamamoto, A N. Heckert, Stefan D. Leigh, Jan Obrzut, F Du, Sheng Lin-Gibson, Minfang Mu, K Winey, R Haggenmueller, Jack F. Douglas
Six PMMA/SWNT(0.5 wt%) nanocomposite samples intended to have different dispersion levels were prepared by the coagulation method using six different concentrations of SWNTs in DMF from 0.05 mg/ml to 1.2 mg/ml. The morphology of the samples was determined

Report of the NIST Workshop on Data Exchange Standards at the Construction Job Site

February 19, 2017
Author(s)
Kamel S. Saidi, Alan M. Lytle, William C. Stone
The Building and Fire Research Laboratory of the National Institute of Standards and Technology, in cooperation with the Fully Integrated and Automated Technology (FIATECH) consortium, sponsored a workshop on data exchange standards at the construction job

Research & Development Program for the Safety of Threatened Buildings

February 19, 2017
Author(s)
William L. Grosshandler
A series of tragic events in the United States over the past decade, punctuated by the collapse of the World Trade Center on September 11, 2001, has exposed the vulnerability of public buildings to uncontrolled fires, explosions, and biological attack

Results of Shear Resistance Tests of Manufactures House Walls

February 19, 2017
Author(s)
Michael A. Riley, R E. Vega
The tests reported herein were intended to gain information on how manufactured home shear walls perform under extreme loads. The specimens tested represent sections from a typical manufactured home. The test results will be used for analytical modeling

Simulating Enclosure Fire Dynamics

February 19, 2017
Author(s)
Howard R. Baum
At least three different physics based approaches to fire dynamics simulations have evolved over the years; lumped parameter or ''zone models'', computational fluid dynamics models based on classical trubulence modeling techniques, and large eddy

Simulating Enclosure Fire Dynamics and Suppression

Author(s)
Howard R. Baum, Kevin B. McGrattan
At least three different physics based approaches to fire dynamicssimulations have evolved over the years; lumped parameter or ''zone models'',computational fluid dynamics models based on classical turbulence modelingtechniques, and large eddy simulations

Simulating Fire Dynamics and Thermal Response of Structural Elements

February 19, 2017
Author(s)
Kuldeep Prasad, Howard R. Baum
Simulation of the effects of severe fires on the structural integrity of builings requires a close coupling between the gas phase energy release andtransport phenomena and the stress analysis in the load bearing materials. The connection between the two is

Smoke Toxicity Data for Fire Hazard and Risk Assessment of Cable Products

February 19, 2017
Author(s)
Richard Gann, Richard D. Peacock, Jason D. Averill, Marc R. Nyden
This report presents the methodology for and results from a series of room-scale fire tests to produce data on the yields of toxic products in both pre-flashover and post-flashover fires. Trays of common household electric cable burned in a room with a

Standardized Cost Structure for the Environmental Industry

February 19, 2017
Author(s)
Harold E. Marshall, Bryan Skokan, Dan Melamed, Karen Guevara, George Bierman
The underlying key to developing successful estimates, tracking projects costs, and utilizing historical project cost information is the development of standardized and well defined hierarchical listing of cost categories. Committees within OECD/NEA and

Structural Analysis of a High-Rise Composite Frame Exposed to Fire

February 19, 2017
Author(s)
Dat Duthinh, Kuldeep Prasad
This paper presents a simplified, planar analysis of World Trade Center Tower 1 (WTC1), starting from a computer simulation of the fire using computational fluid dynamics, and progressing through a thermal and a structural analysis of the damaged structure

Surface and Interface Properties of Crosslinked Amine-Cured Epoxies

February 19, 2017
Author(s)
Tinh Nguyen, G Xiaohong, M Giraud, Mark R. VanLandingham, Jonathan W. Martin
The surface and film/substrate interface properties of a coating system have a strong influence on its adhesion and durability. However, both the surface and interface chemical composition and microstructure of a crosslinked coating applied to a substrate

Survey of the State-of-the-Art for Ocean Wave Energy Conversion Systems

February 19, 2017
Author(s)
Kathryn Butler, Marc R. Nyden, William G. Rippey
It is possible to generate electrical energy from the motion of water due to ocean tides and waves. Oceans are a much more ubiquitous source of flowing water than river gorges, and the ability to efficiently harness this energy could potentially solve many
