Hayashi and the Thermal Physics of Star-Forming Clouds
This brief historical review highlights the early work of Hayashi and his
associates on the thermal physics of star-forming clouds, as summarized in the
temperature-density diagrams first presented by this group. Some of the more
recent developments in this subject, including its application to understanding
stellar masses and to understanding the formation of the first stars, are also
briefly reviewed.Comment: Presented at the meeting on "First Stars IV" in Kyoto, Japan, May
21-25, 2012, honoring Chushiro Hayash
The First Stars: Final Remarks
How did star formation begin in the universe? Some of the questions addressed
at this first meeting on "The First Stars" are summarized here from a
theoretical perspective, and some brief comments are made on what we may have
learned so far.Comment: 5 pages, text only, contains final remarks made at the ESO/MPA

A knowledge based application of the extended aircraft interrogation and display system
A family of multiple-processor ground support test equipment was used to test digital flight-control systems on high-performance research aircraft. A unit recently built for the F-18 high alpha research vehicle project is the latest model in a series called the extended aircraft interrogation and display system. The primary feature emphasized monitors the aircraft MIL-STD-1553B data buses and provides real-time engineering units displays of flight-control parameters. A customized software package was developed to provide real-time data interpretation based on rules embodied in a highly structured knowledge database. The configuration of this extended aircraft interrogation and display system is briefly described, and the evolution of the rule based package and its application to failure modes and effects testing on the F-18 high alpha research vehicle is discussed
