Effective management of movable equipment in a large institutional environment requires a readily accessible database containing accurate up-to-date information. The design and maintenance of an equipment database at the University of Illinois School of Chemical Sciences are discussed. (MLW)

The papers and discussions of the 1975 Pacific Region meeting of the Association for Computing Machinery are presented. Topics included (1) the current and emerging state of the art in data management software and hardware, (2) relational systems with particular attention to new developments in systems for relational data bases, (3) advances in…

This report describes approaches to database translation (i.e., transferring data and data definitions from a source, either a database management system (DBMS) or a batch file, to a target DBMS), and recommends a method for representing the data structures of newly-proposed network and relational data models in a form suitable for database…

This guide to programed learning materials provides teachers and industrial training personnel with information capable of immediate update by means of electronic data processing. Published twice each year, the Guide consists of four parts: appendices (methods of reporting the effectiveness of programed materials, bibliographies, periodicals,…

Organization of communication between the center of an automated system of information exchange and the subscribers to the system is described. The three requirements are: (1) those technical communication means must be chosen which will provide effective and convenient avenues for calls from the subscribers to the center, (2) the required…

Although the indispensibility of access control mechanisms in data secure systems has been recognized, there is a need for more subtle protection and refined control mechanisms. This report describes context protection mechanisms which enable the same data unit to be protected differently in different contexts, the differences being determined by…

This description of software development for the 1970 Survey of Compensatory Education analysis contract is presented in three sections: (1) specifications for data and output, (2) descriptions of the programs written, and (3) problems encountered while processing the data. The section on Specifications contains the description of the data to be…

Describes the operation and numerous capabilities of a British computerized data retrieval system named Prestel. It provides access, through the regular telephone network and a TV screen, to computer-based information supplied by many companies, agencies and commercial outlets. (GA)

The mini-computer is found to be a viable alternative to large computer bio-medical information processing. (Author/RS)

Information based on courses and seminars held at the Second International Summer School on the elaboration of linguistic and literary fundamentals, Pisa, Italy, September 1972; paper presented at the Second International Conference on Linguistics and Translation, October 4-7, 1972, Montreal, Canada.

INDEX, an interactive retrieval program developed at Pepperdine University, is described. It is easy to use and maintain, locates sources of information from a general description of the information needed, requires only a modest investment of time, and is widely applicable. (MLW)

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.…

Intended to be a central source of information on where to acquire statistics on the social and economic characteristics of various racial groups, this report includes references on printed reports, computer tapes, and special calculations. The racial categories of white, negro or black, Indian, Japanese, Chinese, Filipino, Hawaiian, Korean,…
