The paper introduces an information modeling framework to support representation of design artifacts for design databases and repositories. While most artifact representations consist primarily of geometric information, the object oriented design modeling
This paper reports recent progress in the development of a generic molecular dynamics model that accounts for the major chemical reactions involved in the thermal degradation of polymers. The strategy employed in the design of the most recent version of

"Building on Sinkholes" is written for engineers and geologists, in addition to other professionals who work together to solve sinkhole problems. The book provides the reader with a fundamental understanding of the mechanisms of sinkhole formation in
The National Advanced Manufacturing Testbed (NAMT) Framework prototype distributed manufacturing system that serves as a testbed and trial implementation for emerging industry-developed specifications. This report documents the findings of the Framework
Developing a proposed framework for a Computer Integrated Knowledge System (CIKS) for construction materials, components and systems requires a practical approach in order to be utilized by the building materials industry. The need for practicality has
Recent developments for a new spectral irradiance scale realization at the National Institute of Standards and Technology have been targeted to reduce the present relative expanded uncertainties of 0.67 % to 4.34 % (coverage factor of k =2and thus a 2
A preliminary evaluation of the compatibility, spatial resolution, and sensitivity of scanning Maxwell-stress microscopy (SMM) as an in situ diagnostic technique for SPM oxidation of silicon is presented. These results indicate that SMM will provide us
This paper proposes a method to extend the current ISO Guide to the Expression of Uncertainty in Measurement to include the case of known, but uncorrected, measurement bias. It is strongly recommended that measurement results be corrected for bias, however

The popularity of simulated annealing for engineering design applications has grown in recent years, increasing the need for new techniques that improve algoithm performance. Simulated annealing is a time-consuming, iteration-intensive development of
This report documents the presentations and discussions that were made at the NIST workshop on fire performance of high-strength concrete. The workshop was held at NIST in Gaithersburg, MD on Feb 13-14, 1997 in collaboration with the Portland Cement
A new method of describing designs by combining the paradigms of shape aglebras and predicate logic representations is presented. Representing shapes and spatial relations in logic provides a natural, intuitive mehtod of developing complete computer
In lieu of testing each split system air conditioner and heat pump combination, an empirically based calculation procedure may be used for estimating a unit's Energy Efficiency Ratio at the 35 deg C (95 deg F) rating condition, EER(95). The procedure
