Over the past 50 years, the National Institute of Standards and Technology (NIST) has effectively fulfilled its responsibilities under the Federal Fire Prevention and Control Act of 1974. For 70 years prior to that, the National Bureau of Standards (NBS)
The thermodynamic superheat limits of five solvents commonly used in Li-ion batteries are calculated using the Peng-Robinson equation of state. The superheat limit of a two-component solvent mixture is also estimated using the generalized corresponding

The proposed research aims to leverage machine learning to detect thermal operating classes and improve the tenability of firefighters in a commercial building. A total of 3000 simulations are run with FDS to collect temperature from heat detectors. The
A multi-input and multi-output (MIMO) machine learning model is developed to simultaneously detect firefighter's thermal risks across a commercial building structure. A total of 2000 numerical experiments with a wide range of fire and ventilation scenarios
Deep learning model has been a viable approach to forecast critical events in fire development. However, prior to its implementation in real-life firefighting, it is imperative to further understand the black box and assess its rationale. In this paper, an

This report documents an experimental program designed to collect data and information to evaluate the performance of models developed to estimate the electrical high energy arcing fault (HEAF) hazard. This report covers full-scale laboratory experiments
A novel approach for estimating transient heat release rate from fire images and video using deep learning techniques is presented. The heat release rate (HRR) is the most critical parameter in characterizing the fire hazard and thermal effects of a
Bi-directional probes are utilized throughout fire research and testing to measure fire induced flows due to their ability to measure flow which changes direction, and to withstand hostile environments. However, they are not available commercially and
Total absorptivity of glass in the presence of a N2/CO2/H2O is determined numerically using the glass spectral optical properties and the spectroscopic data from RADCAL. Results show that mixture properties (surface temperature, mixture temperature, and

The dissemination of soot particles onto surfaces in a compartment fire is affected by local radiation and temperature gradients. Subsequently, any deposition model must account for the influence of photopheresis and thermophoresis on the deposition

The lack of information on the fire ground has always been the leading factor in making wrong decisions . Wrong decisions can be made by individual firefighters, their local chiefs, and/or the incident commander. Any wrong decision at any level (scale)
