Experiences with Point Cloud Registration

September 1, 2002
Author(s)
Christoph J. Witzgall, Geraldine Cheok
The development of LADAR (laser distance and ranging) technology to acquire 3D spatial data made it possible to create 3D models of complex objects. Because an unobstructed line-of-sight is required to capture a point on an object, an individual LADAR scan

Mobile 3D Visualization for Construction

September 1, 2002
Author(s)
Robert R. Lipman
Until recently, visualization of 3D models required computational resources available only on desktop computers in office environments. With the advance of technology, it is now possible to visualize substantial 3D models on mobile handheld computers in

Optical Reflectance of Metallic Coatings: Effect of Aluminum Flake Orientation

September 1, 2002
Author(s)
Li Piin Sung, Maria E. Nadal, M E. McKnight, Egon Marx, B Laurenti
The orientation of platelet-like pigments in coatings is affected by the processing conditions resulting in appearance variations of the final product. A set of aluminum-flake pigmented coatings having different flake orientations was pre-pared using

Prediction of Cement Physical Properties by Virtual Testing

September 1, 2002
Author(s)
Dale P. Bentz, C Haecker, X Feng, Paul E. Stutzman
Assuring the quality of the massive quantities of cement produced worldwide each year is a daunting task. Currently, the cement industry performs extensive physical testing to assess the quality of their product, resulting in large costs for both materials

Prototype Implementation of an Automated Structural Steel Tracking System

September 1, 2002
Author(s)
K M. Furlani, D T. Latimer, David E. Gilsinn, Alan M. Lytle
This paper discusses the prototype implementation of a system developed by researchers at the National Institute of Standards and Technology (NIST) for the transfer of real-time on-site metrology and metrology-based data for tracking steel frame

Report of the NIST Workshop on Automated Steel Construction

September 1, 2002
Author(s)
Alan M. Lytle, Kamel S. Saidi, William C. Stone, John L. Gross
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. The purpose of the workshop was to

Thermal and Flammability Properties of Polypropylene-Carbon Nanotube Composites

September 1, 2002
Author(s)
Takashi Kashiwagi, E A. Grulke, J N. Hilding, Richard H. Harris Jr., W H. Awad, Jack F. Douglas
Nanocomposites based on polypropylene and carbon nanotubes (up to 2 vol.-%) were melt blended, yielding good dispersion of the nanotubes without using any organic treatment or additional additives. Carbon nanotubes enhance the thermal stability of

Towards the Ultimate Construction Site Sensor

September 1, 2002
Author(s)
William C. Stone, Maris Juberts
The NIST Construction Metrology and Automation Group (CMAG), in cooperation with the NIST Intelligent Systems Division (ISD), is developing performance metrics and researching issues related to the design and development of a Next Generation LADAR sensor

Wind and Seismic Effects: Proceedings of the 34th Joint Meeting

September 1, 2002
Author(s)
Stephen A. Cauffman
This publication is the proceedings of the 34th Joint Meeting of the US-Japan Panel on Wind and Seismic Effects. The meeting was held at the National Institute of Standards and Technology, Gaithersburg, Maryland, during 13-15 May 2002. The proceedings

Modeling Ion Transport Mechanisms in Unsaturated Porous Media

August 27, 2002
Author(s)
J Marchand, E Samson, Kenneth A. Snyder, J J. Beaudoin
The transport of ions in colloids, granular and consolidated porous media is important to a wide variety of environmental and engineering problems. Typical examples are the transport of contaminants in marine sediments, the containment of hazardous waste
