Describes the requirements, data elements, functions and systems design for an online search log which maintains records of search services provided. (CWM)

Examines the present and future capabilities of microcomputers for personal use, and discusses the requirements for such individualized systems, including software and hardware considerations. A glossary is provided, and 31 references are cited. (FM)

This annual directory includes names, addresses, and telephone numbers of major firms involved in the optical information field. Four major product groupings are represented: (1) interactive video; (2) WORM and erasable optical disks; (3) CD-ROM technologies; and (4) optical memory cards. An overview of the past year's developments in this field…

Discusses the wide variety of installation standards currently maintained by publishers of CD-ROM databases and the problems this can cause for users. Hardware and software requirements of various CD-ROM databases intended for use on IBM personal computers and compatibles are described. (five references) (CLB)

Offers suggestions for avoiding common errors in online microcomputer use. Areas discussed include learning the basics; hardware protection; backup options; hard disk organization; software selection; file security; and the use of dedicated communications lines. (CLB)

Presents an improved inverted region quadtree variation called Dynamic Inverted Quadtree that is able to support and index a pictorial database. Pattern-searching algorithms are described, and the space needs of Fully Inverted and Dynamic Inverted Quadtrees are analytically compared based on a model of image randomness expressed as a branching…

Discusses problems in using ASCII for data communications and computers and provides a historical perspective on the development of Unicode, a new universal encoding scheme. The future of Unicode is considered, implications for libraries are discussed, and a sidebar explains how computers store textual data. (LRW)

Describes a study that was conducted to investigate and describe the way in which people organize documents in their offices. Results from the investigation of eight faculty members are discussed and analyzed, the process used to make classification decisions is described, and implications for conventional systems of classification are suggested.…

Reviews the literature relating to the development and application of modern imaging technology between 1987 and 1993. Highlights include image representation, including image data, compression, and image formats; and image access, including indexing and modeling, user interface design, and distributed access. (143 references) (LRW)

Describes a detailed algorithm for fast text compression. Related to the PPM (prediction by partial matching) method, it simplifies the modeling phase by eliminating the escape mechanism and speeds up coding by using a combination of quasi-arithmetic coding and Rice coding. Details of the use of quasi-arithmetic code tables are given, and their…

Describes the design of optimal tree-structured vector quantizers that minimize the expected distortion subject to cost functions related to storage cost, encoding rate, or quantization time. Since the optimal design problem is intractable in most cases, the performance of a general design heuristic based on successive partitioning is analyzed.…

Discusses information retrieval and the use of binary trees as a fast access method for search strategies such as hashing. Proposes new methods based on compact binary trees that provide faster access and more compact storage, explains the theoretical basis, and confirms the validity of the methods through empirical observations. (LRW)

Describes the Accomplishment-Based Curriculum Development model, which provide a cohesive framework for the processes of human performance technology and instructional design. Topics include front-end analysis; behavior characteristics; information storage and retrieval; materials development; and the contributions of Joe Harless to the field.…

Explains the four critical factors needed in designing music suites for middle schools that can help achieve the music program's education goals while accommodating the specialized activities and equipment needs of the suite. Factors examined are the acoustics, floor plan, storage, and equipment needs. (GR)

Examines the intersection of conservation and digital imaging based on guidelines at the Cornell University (Ithaca, NY) library. Discusses the digitization of artifacts; assessing the condition prior to scanning; scanning considerations, including temperature and humidity, lighting, and security; stable storage of artifacts after scanning; and…
