The objective of this work is to investigate the effectiveness of various agents in suppressing flame ignition. Experiments were conducted to determine the
On February 26, 1993, shortly after noon, a bomb exploded in a subterranean garage below the World Trade Center plaza in New York City. The explosions and
A model was developed previously for calculating combined buoyancy- and pressure-driven (i.e., forced) flow through a shallow, circular, horizontal vent where
Fire propagation is driven by the coupling of heat and mass transfer processes between the gaseous and the condensed phases. A significant portion of the heat
Halogenated hydrocarbons are effective and widely used as fire suppressants. Because of their suspected destruction of stratospheric ozone, however, the
Over the last twenty years there has been much debate concerning the interaction of sprinklers and draft curtains in large storage facilities. At issue is

An extensive series of over 140 natural gas fires in a 2/5ths-scale model of a standard room has been previously reported. This work extends the earlier reduced
Virtual reality is a technology which is often regarded as a natural extension to 3D computer graphics with advanced input and output devices. This technology
The possibility of implementing Feynman''s proposal for achieving ultraminiaturization by an iterative process of three-dimensional machines making ever-smaller
Microelectromechanical systems (MEMS) are integrally-fabricated hybrids of micromechanical and microelectronic elements which serve together as sensors
The commercialization and integration of emerging technologies for custom, therapeutic footwear (CTF) manufacturing will provide economic and health-care
The first NIST-traceable SEM magnification calibration standard designed to meet the particular needs of the micromanufacturing industry has been fabricated and
Manufacturing engineering data validation is a critical engineering activity in the product realization process. This paper identifies a set of manufacturing
Textured laps can be created by slumping uniform thin films of appropriate materials over textured substrates that have been generated to the required figure
This paper describes a software design for implementing compensation of errors detected by process-intermittent gauging. This is the function of one control
There is a pressing need in the semiconductor industry to determine the dimensions of lithographically produced features on wafers and masks down to the l0?nm
