Gas Turbine Engines (GTE) have the highest power-to-weight ratio among Internal Combustion Engines (ICE). Its modularity and ability to utilize various types of fuel make it highly recommended in power plants, naval transportation, and, of course, the most equipped in aviation. The lack of GTEs' real data is increasing a recognized need for…

Discusses the use of optical character recognition (OCR) for inputting documents in an information retrieval system and describes a study that used an OCR-generated database and its corresponding corrected version to examine query evaluation in the presence of noisy data. Scanning technology, recognition technology, and retrieval technology are…

Information gathered from faculty members about nontextbook educational materials is reviewed by the Association of American Medical Colleges before cataloging, indexing, and abstracting at the National Library of Medicine for listing in AVLINE, a computer information service available through the MEDLARS system. (JT)

Appendix A is concerned with the characteristics of the user communities and of the information service centers as important factors in the representation of an information service system. The basic characteristics of both centers and communities include their number, size, geographic distribution, and scope of interest. These characteristics are…

The transfer of information through space and time in communication systems is often accompanied by significant delays which give rise to meaningful storage problems. Mathematical models have been developed for the study of these kinds of problems which are applicable to the design of manual, library-type, or mechanized information storage and…

This is one of a series of reports based on an ongoing reality test of systemic evaluation for instructional decision making. This feasibility study is being carried out by the Center for the Study of Evaluation with the Laboratory in School and Community Relations at a suburban Los Angeles high school (called Site A). Viewing a school as a…

The ERIC network conversion to an OCR (Optical Character Recognition) mode of data entry was studied to analyze the potential effectiveness of OCR data entry for future EPC/s (Editorial Processing Centers). Study results are also applicable to any other system involving decentralized bibliographic data capture and conversion functions. The report…

One of a series of manuals developed by the Home and Community-Based Career Education Project, the publication presents the activities of the project's research and evaluation component, which continually informs the staff about project development and describes client characteristics, needs, decisions, and plans. Generic issues which must be…

The feasibility of using a centralized data processing facility to sever a large group of secondary schools and the capabilities of two alternative systems were investigated. The population to be served included 100,000 students in grades 9-14 attending 50 schools in an area having a hundred mile radius. Service requirements were defined to…

Measures, tools, and techniques applicable to the performance measurement of computer communication networks are described for technicians who procure computer services from a remote access network. Cost considerations are discussed as a major component of evaluation, and measurement and evaluation methodologies are surveyed. External measurement…

A comparison of costs for computer-based searching of Psychological Abstracts and Educational Resources Information Center (ERIC) systems by the New York State Library at Albany was produced by combining data available from search request forms and from bills from the contract subscription service, the State University of New…

Two regional educational data processing centers, operating in the field of school planning and services, are described in detail and used as examples to aid in establishing similar information systems. Instructions for creating a center are offered in general: developing an event chart and defining objectives, scope, staff characteristics,…

This monograph contains four position papers and two conference papers from the Systemic Evaluation Project (fiscal year, 1984) on the methodological issues associated with applying a comprehensive information system in a secondary school setting. These papers represent work in progress at a suburban Los Angeles high school field test of systemic…
