Extracting STEP Geometry and Topology from a Solid Modeler: Parasolid-to-STEP

June 1, 1991

Author(s)

Thomas R. Kramer

Parasolid is a commercial solid modeling software system. It uses a manifold boundary representation. STEP (STandard for the Exchange of Product model data) is an emerging international standard. Included in STEP are proposed standards for Topology and

High resolution spectroscopy using fiber lasers

June 1, 1991

Author(s)

Sarah L. Gilbert

Fiber lasers show potential for use in high resolution laser spectroscopy. Tunable, single-longitudinal-mode operation has been achieved with fre.e-running laser linewidths of about 1 MHz. It would be straightforward to obtain much narrower linewidths

National PDES Testbed Implementation Plan: Management and Technical Support Activities

June 1, 1991

Author(s)

Charles R. McLean

The National PDES Testbed is just one small, but critical, component of a larger international effort to develop product data exchange capabilities. As such, Testbed efforts must be coordinated with other organizations. The Management and Technical Support

Performance of 1/3-Scale Model Precast Concrete Beam-Column Connections Subjected to Cyclic Inelastic Loads. Report No. 2

June 1, 1991

Author(s)

Geraldine S. Cheok, Hai S. Lew

Results are presented from the experimental test program on precast concrete beam-column connections subjected to inelastic cyclic loads being conducted at the National Institute of Standards and Technology. This report is the second in a series and covers
