This study examines the energy consumption of automatic ice makers installed in domestic refrigerators. The purpose of this research is to determine a method of
A series of experiments are described in which helium was released at constant rates into a 1.5 m 1.5 m 0.75 m enclosure designed as a -scale model of a two car
It is desirable to replace Halon 1301, CF3Br, as the fire suppressant used in cargo bay fire suppression. Unfortunately, some candidate agents for replacing

This report presents an experimental and computational study of two steel beam-column assemblies, each comprising three columns and two beams. The two beam
When an emergency occurs, it is not always sufficient to simply initiate alarm bells. Individuals may not know what the alarm bell means and, in turn, may
High-temperature metallic seal performance tests were performed. All the tests were conducted at either 800 °C or 427 °C for 9 hours in a electrical furnace. In

We report on measured peer-to-peer (ground-based) wireless channel characteristics for an urban environment in two public safety frequency bands. Results are
Strategies are developed that make use of signals from smoke and heat alarms to deduce conditions in a room for both flaming and smoldering fires. The issue

This document is intended to provide practicing engineers and building code officials with a technical resource that contains the current best practice for fire
The computer model CONTAM was used to simulate the spread of smoke in a house with a working furnace during smoldering fires. Three smoldering experiments from
The transformation of chemical analyses to phase estimates via the Bogue calculations has been successfully used by industry for the past 70 years. Since its
Aerodynamic measurements of wind-induced pressures on structures are required for the codifi-cation of design wind loads. However, the reliable measurement of
Experiments conducted in a Toledo Ohio school are used to examine the use of signals from simulated heat detectors by incident command. Two approaches are

The time that it takes an occupant population to reach safety when descending a stairwell during building evacuations is typically described by measureable
The research presented here is the first report of fabricating mulitwalled carbon nanotube (MWCNT) based thin coatings on polyurethane foam (PUF) using Layer-by
This is the first reported use of Layer-by-Layer (LBL) assembly to fabricate thin film coatings on polyurethane foam, of incorporating carbon nanofibers (CNF)
Although previous studies have shown that shade trees can reduce summertime electricity use, none have compared these reductions to other common energy
Atmospheric boundary layer winds experience two types of effects due to friction at the ground surface. One effect is the increase of the wind speeds with

An inexpensive green laser pointer was found to emit 20 mW of infrared radiation during normal use. This is potentially a serious hazard that would not be
Here we report on the testing and measurements of the ad hoc array concept in buildings. The overall concept is to use randomly located or placed wireless
The purpose of this study was to evaluate measurement uncertainties introduced into time delay calibrations of multimode fiber reference spools. While the
Time-domain analyses of wind effects on high-rise structures have been made possible in recent years by advances in wind pressure measurement and computer
The U.S. National Institute of Standards and Technology (NIST) conducted a study for CDC to examine the impact of distance of gasoline-powered portable electric
