HIERtalker: A default hierarchy of high order neural networks that learns to read English aloud

Description: A new learning algorithm based on a default hierarchy of high order neural networks has been developed that is able to generalize as well as handle exceptions. It learns the ''building blocks'' or clusters of symbols in a stream that appear repeatedly and convey certain messages. The default hierarchy prevents a combinatoric explosion of rules. A simulator of such a hierarchy, HIERtalker, has been applied to the conversion of English words to phonemes. Achieved accuracy is 99% for trained words and ranges from 76% to 96% for sets of new words. 8 refs., 4 figs., 1 tab.

SAFT-UT utilities: Reference manual

Description: This manual is intended to give the user a complete command and operation reference for using the SAFT-UT utilities in the VMS environment. It augments two additional documents, the Guide to SAFT-UT Principles and Conventions and the Interface and Installation Guide. An understanding of the contents of the Guide to SAFT-UT Principles and Conventions is a recommended prerequisite to the use of the SAFT-UT utility programs.

Hanford Meteorological Station computer codes: Volume 3, The TANK computer code

Description: At the end of each graveyard shift the Hanford Meteorological Station (HMS), operated by Pacific Northwest Laboratory, issues a forecast of eight hourly average wind speeds and wind gusts for the 50-ft level. The Hanford Waste Management crew uses this forecast, called the tank farm forecast, to schedule daily work loads. The forecast covers an 8-hour period (0800 to 1600 during Pacific Standard Time (PST) or 0700 to 1500 during Pacific Daylight Time (PDT)) and the day-shift forecaster may modify the tank farm forecast to reflect changing wind conditions. The TANK computer code is used to archive these forecasts and apply quality assurance checks to the forecast data. The code accesses an input file, which contains the date of the previous forecast, and an output file, which contains tank farm forecasts for the current month. The program includes a data entry form consisting of 12 fields that must be filled in by the user. The information entered on the form is appended to the monthly forecast file, which provides an archive for the tank farm forecasts. This volume describes the implementation and operation of the TANK computer code at the HMS.

Hanford Meteorological Station computer codes: Volume 4, The SUM computer code

Description: At the end of each swing shift, the Hanford Meteorological Station (HMS), operated by Pacific Northwest Laboratory, archives a set of daily weather observations. These weather observations are a summary of the maximum and minimum temperature, total precipitation, maximum and minimum relative humidity, total snowfall, total snow depth at 1200 Greenwich Mean Time (GMT), and maximum wind speed plus the direction from which the wind occurred and the time it occurred. This summary also indicates the occurrence of rain, snow, and other weather phenomena. The SUM computer code is used to archive the summary and apply quality assurance checks to the data. This code accesses an input file that contains the date of the previous archive and an output file that contains a daily weather summary for the current month. As part of the program, a data entry form consisting of 21 fields must be filled in by the user. The information on the form is appended to the monthly file, which provides an archive for the daily weather summary. This volume describes the implementation and operation of the SUM computer code at the HMS.
