This report is an analysis of the potential of tunable laser diode absorption spectroscopy (TDLAS) for recording carbon monoxide (CO) concentrations in hydrogen fuel cell environments characteristic of those present during reforming of organic fuels
This chapter is aimed at illustrating contemporary Computational Fluid Dynamics (CFD) capabilities for compartment fire applications. We choose to use the Fire Dynamics Simulator (FDS) for illustration purposes. FDS is developed by the National Institute

This paper discusses three interrelated aspects of modeling scalar transport, mixing and combustion, in the context of large-eddy simulation (LES). In terms of passice scalar modeling, we find deom heated wake measurements that whereas the kinetic energy
This chapter introduces the various construction automation concepts that have been developed over the past few decades and presents examples of construction robots that are in current use (as of 2006) and/or in various stages of research and development.
The concentrations of certain gases generated during fire suppression were determined as part of the evaluation of the automatic fire extinguishing system for the Advanced Amphibious Assault Vehicle. The measurements were performed in a test facility
There is a growing awareness of the benefits that could accrue from improving the technologies used by the Nation s $995 billion/year building and construction industry. Some possibilities for improvement in the performance of construction materials
Continuous monitors were employed for one year in an occupied townhouse to measure ultrafine, fine and coarse particles, air change rates, wind speed and direction, temperature and relative humidity. A main objective was to document long-term variation in

Layered double hydroxide/polyamide 6 nanocomposites (LDH/PA6) were prepared from organo-modified LDH by melt processing. The anionic exchange capacity of LDH was varied in order to investigate its influence on the degree of exfoliation. LDH were dispersed

The National Institute of Standards and Technology (NIST) is developing a real-time control system for a robotic crane (the NIST RoboCrane) that will perform automated structural steel pick-and-place operations. The control system architecture is based on

Following Irminger s 1894 aerodynamic tests, Flachsbart s pioneering boundary-layer wind tunnel experiments in 1932, and University of Western Ontario (UWO) 1970 s tests, considerable progress has been achieved in low-rise building design for wind. Owing

Recently we have developed several new high throughput (HT) methods to quantitatively evaluate the flammability of flame retarded (FR) polymers. The most recent results are due to the efforts of the High Throughput Methods for Materials Flammability

During extrusion processing dielectric spectroscopy was conducted on polyamide-6 (PA6) and organoclay/polyamide-6 nanocomposites. Off-line curve fitting of the on-line dielectric data generated dielectric dispersion parameters that appear sensitive to
