The ability to efficiently optimize or re-optimize an algorithm for high performance on a particular processor architecture is crucial in a wide spectrum of engineering and scientific applications. To help bridge the gap between fully automated optimization, which does not reliably produce optimal code, and fully manual optimization, which is…

This paper focuses on graphics and how they can be created, in real time, from information stored in a database, and the application of this technique to computer-assisted instruction (CAI). It is noted that this is a special case of the general trend towards endowing instructional systems with a degree of decision-making or design expertise, as…

Presents an information systems navigation approach using a combination of functionalities encountered in classification processes, Hypertext systems, and information retrieval systems. The first version of the SYRIUS system is described, with emphasis on the user's graphic interface which integrates these functionalities. (26 references) (EA)

Describes a graphic modeling, natural language processing system, VerbalImage, which mimics features of human shape reasoning. Subjects read the same text description and were able to recognize the image generated by the computer from among a series of other computer-generated images. Performance on task was as good as for a control group…

This examination of the effectiveness of various methods of cuing users to their location in a videotex information system used five different versions of an electronic edition of a college catalog: "simple" (no cues), "headers" (textual cues), "color" (color cues), "icons" (graphic cues), and…

Describes the Book House, an interactive, multimedia online public access catalog (OPAC) developed in Denmark that uses icons, text, and animation. An alternative design model that addresses problems in OPACs is described; and database design, system navigation, use for fiction retrieval, and evaluation are discussed. (20 references) (MES)

Discusses ways that supercomputers are being used in the manufacturing industry, including the design and production of airplanes and automobiles. Describes problems that need to be solved in the next few years for supercomputers to assume a major role in industry. (TW)
