Monte Carlo Tool

Data provided by  National Institute of Standards and Technology

This tool is used to implement Monte Carlo analysis, which uses probabilistic sensitivity analysis to account for uncertainty. This tool is developed to follow the simulation segment of ASTM E1369. This technique involves a method of model sampling. Specification involves defining which variables are to be simulated, the distribution of each of these variables, and the number of iterations performed. The software then randomly samples from the probabilities for each input variable of interest. Three common distributions that are used include triangular, normal, and uniform.

Manufacturing Cost Guide

Data provided by  National Institute of Standards and Technology

The Manufacturing Cost Guide is a tool that estimates the costs that US manufacturers face and can be used to help gauge the potential returns on manufacturing industry research projects through cost reductions. These costs are grouped into various standardized categories such as the North American Industry Classification System (NAICS) and the Standard Occupational Classification (SOC) system along with other non-standardized costs.

The tool can be used to answer questions such as:

Data from Influence of Fire on the Lateral Resistance of Cold-Formed Steel Shear Walls - Phase 2

Data provided by  National Institute of Standards and Technology

Twenty-two 2.7 m by 3.7 m shear wall specimens consisting of 150 mm wide CFS framing were tested. All walls were designed to achieve a 1-hour fire-resistance rating per American Society for Testing and Materials (ASTM) standard E119. Heating was applied to the side of the wall opposite to the side where the shear-resisting elements are located; it is assumed that the shear-resisting elements line an egress corridor and the fire occurs in a room adjacent to the corridor.

Analysis and Optical Modeling of Individual Heterogeneous Asian Dust Particles Collected at Mauna Loa Observatory

Data provided by  National Institute of Standards and Technology

This project involved the analysis and optical modeling of atmospheric dust particles collected at Mauna Loa Observatory in Hawaii. Dust from the Asian mainland was identified in filter samples with computer-controlled scanning electron microscopy (CC-SEM). Individual Asian dust and marine background air particles were further examined using focused ion-beam (FIB) SEM and energy dispersive x-ray spectroscopy (EDX). The particles were heterogeneous in that they had multiple mineral phases, including an iron-containing phase which was compositionally minor but optically important.
