Abstract

DOE contracted with Sandia to install a radar acquisition system (RAMS) to gather aircraft flight data near the Pantex Plant in Amarillo, TX. To support this effort, data reduction tools were needed to help analyze the radar data. Plot-flight is one of several data reduction tools that comprise the Sandia Airspace Recording System (SARS). The radar data is needed to support the Pantex Environmental Impact Study. Plot-flight is a DOS-based plot program that allows analysts to replay pre-recorded air traffic over Albuquerque and Amarillo. The program is flexible enough to permit replay of daily flights either sequentially, by range, or by Beacon ID. In addition to replay, the program is setup for data entry. Analysts can correlate electronic aircraft flight data to the green strip flights logs obtained from the local air traffic control center. The green strips are used by air traffic controllers to record each scheduled flight. The green strips have information not available electronically such as aircraft type and aircraft ID. This type of information is necessary to accommodate the current models used in aircraft crash analysis. Plot-flight correlates the hand-written information from the green strips to the recorded aircraft flight. Document type: Report

Abstract

A study was made of the flow of data and the simultaneous processing needed to reduce the 10/sup 7/ to 10/sup 8/ triggers per second expected at ISABELLE to a number of events on the order of 10 to 100 per second which would be written on magnetic tape. It was assumed that within 100 ns of the event a fast pretrigger would have reduced the data rate to at most 10/sup 7/ per second. At that point, data from all sense elements in the experiment would be fed into a 1-..mu..s-long pipeline. Within the first 1 ..mu..s (while the data are in the first pipeline) another level of triggering would reduce the trigger rate to at most 10/sup 6/ per second. The data would then be fed into a second pipeline which is 50 ..mu..s long. During the 50 ..mu..s the data are in the second pipeline, a more sophisticated level of triggering (slow trigger) would reduce the trigger rate to a level that can be handled by standard data processing techniques (microprocessors or larger machines), i.e., 10/sup 2/ to 10/sup 3/ per second. The pipelines and the buffer between them, a sequential address memory, are described first, andmore » then several alternative schemes for the pretrigger and slow trigger are presented. 10 figures.« le Document type: Report

Abstract

This report covers the design and fabrication of a conformable eddy current array useful for the mapping and measurement of external corrosion on a transmission pipeline. The feasibility of the basic measuring approach was demonstrated and the general guidelines for sensor design were disclosed in a previous project. This project was concerned with design of a practical array, development of interface electronics, and design of the operation and analysis software. A prototype system was constructed, checked out, and demonstrated on natural corrosion in a field environment. Document type: Report

Abstract

This report documents work performed in the first quarter of the project entitled: ''Technologies to Enhance Operation of the Existing Natural Gas Compression Infrastructure''. The project objective is to develop and substantiate methods for operating integral engine/compressors in gas pipeline service, which reduce fuel consumption, increase capacity, and enhance mechanical integrity. The report describes the following work: preparation and submission of the Research Management Plan; preparation and submission of the Technology Status Assessment; attendance at the Project Kick-Off meeting at DOE-NETL; formation of the Industry Advisory Committee (IAC) for the project; preparation of the Test Plan; acquisition and assembly of the data acquisition system (DAS).
