Analyzes computer terminal memory performance in terms of overflow probability and average queueing delay, and presents new method to derive a closed expression for data arrivals with Erlangly distributed interarrival times and an approach to derive steady state probability expressions of the terminal memory content process. Twenty references are…

Presents a system model for transmission of input data that is coming from terminals of users in a limited user resource-sharing environment. Performance of a mini/microcomputer receiving mixture of picture-phone terminal data is analyzed with constant service times, synchronous transmission, and single-server interruptions through first-order…

Describes InfoStation, an information system which integrates a microcomputer with a videotape recorder and facsimile machine, to provide backup storage and selective retrieval of both analog and digital information. The features and applications of the system are described in detail and compared with other computer storage methods. (CLB)

Improvements in the technology associated with the information sciences will have their primary potential impact on the distribution of costs, information flow level, information availability, and use among information channels. This improvement implied not only a capability to perform a given function, but a lower cost. For example, the trend…

Digital materials are vulnerable to a number of different kinds of failures, including decay of the digital media, loss due to hackers and viruses, accidental deletions, natural disasters, and bankruptcy of the institution holding the collection. Digital archives can best survive failures if they have made several copies of their collections at…

After discussing the nature of timeliness and its importance to the user of information systems, this document examines the factors which affect timeliness in three subsystems of the scientific communication system. The first subsystem moves a document from the existence of new knowledge to the point of entry into an information system; the second…

This research proposes a conceptual structure for an Environmental Information System. An Eco-Systems approach is employed maintaining whole units of analysis allowing for collection and storage of information of use to regional environmental planning and design. The suggested system design incorporates some of the basic concepts of the two…

Fifteen experts in the fields of medical education and biomedical communications identified 95 events and conditions that might occur during the next 20 years in the area of biocommunications, health care delivery, and medical education; this document contains the verbatim comments provided as responses to these conditions by the study…

This study is an outgrowth of recommendations made in a report issued by the Council on Library and Information Resources (CLIR) in 2001 (Nichols and Smith 2001). The report made three broad recommendations for addressing print preservation: (1) Establish regional repositories to house and provide proper treatment of low-use print matter drawn…

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…

A true library network is the interfacing of more than one kind of system (i.e., public and academic) rather than cooperation between libraries of the same type. Networks may take many forms, such as: cooperative development of resources, with assignment of subject areas to separate facilities; a cooperative storage system, with the libraries…

Summarizes the historical trend of distributing computer power within universities, and describes a model for an information technology environment for higher education. Based on a broad distribution of information and computing power, this model allows users to share information using micro- and minicomputers. (CLB)

This document represents the first of five components of a project conducted to design a comprehensive information system (termed SYSTEM) for identifying, selecting, and disseminating relevant military curriculum materials to civilian vocational and technical education programs. This particular report identifies, reviews, and analyzes existing…

Describes software selection criteria considered for use with the bibliographic database of the Development Information Network for South Asia (DEVINSA), which is located in Sri Lanka. Highlights include ease of database creation, database size, input, editing, data validation, inverted files, searching, storing searches, vocabulary control, user…

This document represents the fifth of five components of a project conducted to design a comprehensive information system (termed SYSTEM) for identifying, selecting, and disseminating relevant military curriculum materials to civilian vocational and technical education programs. This particular document suggests the design, operating procedures,…
