A syntax methodology provides a descriptive mechanism to enable machine readable storage and retrieval of numeric data contained in bibliographic documents. The body of this paper treats the nature of "the syntax,""the data element," and the language by which this syntax is expressed. A discussion of the methodology illustrates…

Presents a new image compression algorithm that employs some of the most successful approaches to adaptive lossless compression to perform adaptive online (single pass) vector quantization with variable size codebook entries. Results of tests of the algorithm's effectiveness on standard test images are given. (12 references) (KRN)

Evaluates the performance of different methods of data compression coding in several situations. Huffman's code, arithmetic coding, fixed codes, fast approximations to arithmetic coding, and splay coding are discussed in terms of their speed, memory requirements, and proximity to optimal performance. Recommendations for the best methods of…

Presents an inference algorithm that produces a weighted finite automata (WFA), in particular, the grayness functions of graytone images. Image-data compression results based on the new inference algorithm produces a WFA with a relatively small number of edges. Image-data compression results alone and in combination with wavelets are discussed.…

The Computer Assisted Reference Locator (CARL) is a computer-based information retrieval system which uses coordinate indexing. Objectives established in designing the system are: (1) simplicity of reference query and retrieval; (2) ease of system maintenance; and (3) adaptability for alternative computer systems. The source documents input into…

Computers have been used in a variety of applications for athletics since the late 1950's. These have ranged from computer-controlled electric scoreboards to computer-designed pole vaulting poles. Described in this paper are a computer-based athletic injury reporting system and a computer-assisted football scouting system. The injury reporting…

The School District of Philadelphia has had a continuously maintained computerized data system for its 270,000 pupils since 1967. This paper outlines: the general procedures and descriptions of the file; the need for establishing a pupil data-base file; the systems products and services; its value to research and evaluation as well as to the…

This paper describes a computer support system that eliminated many of the problems associated with the usual methods of transcribing and analyzing questionnaire data. The system was created to support the course evaluation system at Athabasca University, a distance education university in Canada. The courses evaluated were all home study courses,…

A description of a retrospective document retrieval system is given in which equifrequent fragments are used as language elements for compression coding and retrieval. The critical parameters governing the system are identified, and restrictions imposed by the parameters on the selection of fragments are outlined. Changes necessary in the…

The preparation of a data tape and users guide is reported. The tape contains about 700 cases with nearly two thousand variables collected over a three-year period as part of a curriculum evaluation study. The student group is the eleven- to fourteen-year-old population that participated in the field test of the BSCS Human Sciences Program.…

The importance of information systems management to institutional research efforts of colleges and universities is discussed. The goal of information system management is to make an institution's information system more consistent, efficient, and informative. Each of the different functions of the university, such as admissions and registration,…

Discusses geoprocessing, a computer mapping technique used by the Portland (Oregon) School District in which geographic analysis and data processing are combined. Several applications for administrative decision-making are discussed, including bus routing and redistricting. (JJD)

This report describes the development in 1986 of a management information system by the Sacramento City (California) Unified School District for use in high schools. A nine-page attachment, which comprises two-thirds of the report, offers profiles of selected schools drawn from the databases. Data sets of 200 information items, collected from all…

The unparalleled residue of unsifted primary materials relating to the nineteenth century London theater present tremendous opportunities and challenges for theater historians. The histories of individual London theaters may be studied for insights into changes that distinguished nineteenth century theater from that of the eighteenth century; and…

The process of planning the role of the microcomputer in higher education administration is investigated through a survey of a sample of universities and colleges in California engaged in such efforts, and through a review of literature in education as well as computing. A major objective of the study was to systematically investigate the…
