Water is ubiquitous in the atmosphere. Unfortunately, adhesive bonding is susceptible to the environmental attack of water leading to significant depreciation in joint strength and subsequently to premature failures [1-6]. This susceptibility of bonding to
The CYCLE_D package simulates vapor compression refrigeration cycles that use pure refrigerants or mixtures of refrigerants. The model can simulate a basic subcritical or transcritical refrigeration cycle, both with or without a liquid-line/suction-line
The National Institute of Standards and Technology (NIST) has a Reduced Risk of Fire Spread in Wildland-Urban Interface (WUI) Communities research program. The program objective is to develop, by the end of FY2013 first generation tools for improved risk

In 2007, the latest year for which construction data are available, the value of construction put in place was $1.1 trillion. Statistics on the total cost of fire in the U.S. are published by the National Fire Protection Association (NFPA). Of particular
Wind loads for use in structural design are based in part on extreme value analysis of historical wind data, and limitations on the quantity and spatial resolution of wind data pose a significant challenge in such analyses. A promising source of additional
This paper presents Version 4.0 of the CYCLE_D: NIST Vapor Compression Cycle Design Program. The model can simulate a basic subcritical or transcritical refrigeration cycle, both with or without a liquid-line/suction-line heat exchanger. In addition, the
A series of 14 experiments was conducted in 7-story building to evaluate the ability of positive pressure ventilation fans, wind control devices and floor below nozzles to mitigate the hazards of a wind driven fire in a structure. Each experiment started
This paper discusses the breakthroughs in science and engineering that have brought fire testing technology to its current state of maturity and provides insight into the possibilities for future fire test development by highlighting some areas where

Carbon nanotubes (CNTs) are increasingly incorporated in polymers to enhance their mechanical and electrical properties. However, organic polymers are prone to degrade when exposed to UV radiation. Therefore, CNTs in a polymer nanocomposite could
The current work explored how choice of surfactant, fire temperature and processing pressure affect the assembly process for particles in the barrier layer. The underlying assumption was that the nano-structure of the ceramic portion of the barrier layer
Polymer backbone scission reactions were studied computationally using polyethylene macromolecules as prototypes. Classical RRKM modeling, molecular dynamics, transition state theory, and molecular mechanics were used as research tools. The results

Computer simulation models to accurately predict the electrical performance of photovoltaic modules are essential. Without such models, potential purchasers of photovoltaic systems have insufficient information to judge the relative merits and cost
This document reports on the test results of an evaluation of the image quality of thermal imaging cameras used by the fire service. The test methods used were consistent with the image quality test methods included in Draft National Fire Protection
Probabilistic models are developed for directional wind speeds in hurricane, thunderstorm, and synoptic wind storms. The models, calibrated to data, are used to generate synthetic directional wind speeds over periods of arbitrary length and to assess the
Microgravity experiments and computations have been conducted to elucidate stabilization and extinguishment mechanisms of methane diffusion flames, in the cup-burner configuration, with CO 2 added gradually to a coflowing air or oxygen-enriched stream. The
This report documents the changes that have been made to the previous structure of the HR_DAD software, thereby developing the program HR_DAD_1.1 capable of calculating efficiently the response of large scale real world tall buildings made up of many
Pool fires are buoyancy-driven diffusion flames fed by the vaporization of a horizontally aligned, condensed-phase fuel. Volatile liquids and solids can serve as fuels for pool fires. The characteristic length of a pool fire is the pool diameter, d. This
An assessment of uncertainties for the National Institute of Standards and Technology (NIST) 1016 mm Guarded-Hot-Plate apparatus is presented. The uncertainties are reported in a format consistent with current NIST policy on the expression of measurement
Errata to the NIST Reports of the Federal Building and Fire Investigation of the World Trade Center Disaster,NCSTAR 1A, NIST NCSTAR 1-9, and NIST NCSTAR 1-9A. (January 2009, April 2012 and June 2012) These changes do not alter the findings, conclusions, or
