The National Institute of Standards and Technology (NIST) has been conducting research in crane automation since the mid 1980 s. A robotic crane (RoboCrane) based on an inverted, cable actuated Stewart-Gough platform principle was invented at NIST at that
This year, the National Institute of Standards and Technology (NIST), formerly the National Bureau of Standards (NBS), turned 100 years old. During that century, NBS/NIST measurement technology has done much to enable the business of fire safety. Today
This paper presents an improved method to design buildings to resist high wind. The method consists of using databases of pressures measured in wind tunnel tests and applying these pressures in nonlinear structural analyses, hence the name nonlinear
The earliest work in the United States on the development of portland cement standards was conducted by the American Society of Civil Engineers in the late 1800s. ASTM and the Federal government joined the effort in the early 1900s and ASTM C9 American

Fire spread through suspended vegetation, such as tree crowns, is a basic component of wildland fires. Most models of fire spread do not resolve the burning of individual trees. Instead, fire spread through a forest canopy, representing a collection tree
Brancusi s Endless Column (T rgu-Jiu, Romania) is an interesting case study in bluff body aeroelasticity. It has been referred to as aeroelastically indifferent owing to its remarkable aeroelastic stability with respect to galloping. The column s behavior
Brancusi s Endless Column (T rgu-Jiu, Romania) has been referred to as aeroelastically indifferent owing to its remarkable aeroelastic stability. The column s behavior has been attributed to its unconventional shape. However, calculations presented here
Experimental measurements of laser-induced ionization were performed for ethene/air premixed flames operated near the soot inception point. Soot was ionized using a pulsed laser operated at 532 nm. The ionization signal was collected with a tungsten
The paper presents a brief overview of the National of Institute of Standards and Technology's (NIST) efforts towards standardizing methods for the performance evaluation of 3D imaging systems. 3D imaging systems are used to rapidly capture (thousands of

The NIST Construction Metrology and Automation Group (CMAG), in cooperation with the NIST Intelligent Systems Division (ISD), is developing performance metrics and standard tests for the evaluation of 3D imaging systems used in autonomous mobility
In designing a building that will perform reliably over a specified time, a designer needs a vast amount of information about the performance of the available materials and components (hereafter referred to, collectively, as maerials) in the likely service
This document specifies the ISO 10303 application protocol (AP) Edition 2 for the exchange of spatial configuration information of process plants, plant systems and ship systems. This includes shape characteristics, spatial arrangement characteristics, and

The performance of polyurethane (PU) composites reinforced by isocyanate-functionalized multi-walled carbon nanotubes (NCO-fMWCNT) and isocyanate-functionalized carbon nanofibers (NCO-fCNF) has been investigated. NCO-fCNTs and NCO-fCNF were prepared using
A successful simulation of compartment fires using computational fluid dynamics (CFD) must be able to adequately model three significant phenomena: the combustion of fuel, the mixing caused by the buoyancy of hot gasses, and the removal of heat from the

As a result of the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer and the 1990 U.S. Clean Air Act, there began a movement toward phaseout of the use of the halon fire suppressants. The HOTWC was initiated as a forum for such contributory
A recently developed capability allows the routine creation, from National Weather Service Automated Surface Observing System (ASOS) records, of separate sets of extreme non-thunderstorm and thunderstorm wind speeds. Using such records it is possible to
The Building and Fire Research Laboratory of the National Institute of Standards and Technology, in cooperation with the American Institute of Steel Construction, sponsored a workshop on automated steel construction on June 6-7, 2002, at the NIST
This document provides an overview of a new ISO standard, ISO/CD 10303-231, for exchanging process engineering information among process design and process simulation software tools and presents three views of this standard. First, it attempts to forecast
complishments and current standards development activities of the American Society for Testing and Materials (ASTM) Subcommittee E06.23, Lead Hazards Associated with Buildings, are summarized. Since the inception, the subcommittee has developed 24
The events of September 11 have generated renewed interest in the use of protected elevators for egress and access. U.S. building codes contain requirements for accessible elevators for assisted evacuation of people with disabilities. Firefighter lifts
A dual burner apparatus has been developed for the purpose of assessing the flammability of a mattress/foundation combination in a manner that correlates with its real world fire behavior. This document sets out the detailed procedure for employing this
This paper presents a critical analysis of the economic impacts of past, ongoing, and planned collaborative research for developing and deploying cybernetic building systems (CBSs) in office buildings. NIST is participating in a public-private partnership
Field inspection (including sampling) and laboratory testing of concrete and concrete-making materials are key activities ensuring that constructed facilities are durable and long lasting. Standards which promote the quality of testing are prepared by ASTM
