Mathematical modeling problems encountered in many disciplines are discussed in terms of the modeling process and applications of models. The models are classified according to three types of abstraction: continuous-space-continuous-time, discrete-space-continuous-time, and discrete-space-discrete-time. Limitations in different kinds of modeling…

Administrators at small colleges are devising innovative policies to compete with recruiters from corporations and large universities to attract computer-science professors and hold on to them. Williams College offers higher salaries, while Middlebury College pays computer-science instructors as administrators on 11-month contracts. (MLW)

The controversy over whether or not machines can think has attracted the attention of philosophers, psychologists, neurologists, computer scientists, and writers of science fiction. Various topics and issues related to this controversy are discussed, including turing machines and the relationship between computer history and mathematical…

Presents a summary of nine research reports from a National Educational Computing Conference research workshop whose purpose was to bring together researchers who have been conducting gender-related research in computer science education. Three subgroups discussed the issues of exposure, attraction, and retention of women to computer science. (MDH)

Presents two examples which illustrate the usefulness of ideas from cellular automata. First, Lee's algorithm is recalled and its cellular nature shown. Then a problem from digraphs, which has arisen from analyzing predecessing configurations in the famous Conway's "game of life," is considered. (Author/JN)

In an attempt to specify in some canonical terms what many heuristic programs known as "expert systems" do, an analysis was made of ten rule-based systems. It was found that these programs proceed through easily identifiable phases of data abstraction, heuristic mapping onto a hierarchy of pre-enumerated solutions, and refinement within this…

Scientists feel that progress in artificial intelligence and the availability of thousands of experimental results make this the right time to build and test theories on how people think and learn, using the computer to model minds. (MSE)

Examines high school and small college applications of computer bulletin-board service. Considers administrative problems. Suggests further applications. (JM)

Built-in data structures are the registers and memory words where binary values are stored; hard-wired algorithms are the fixed rules, embodied in electronic logic circuits, by which stored data are interpreted as instructions to be executed. Various topics related to these two basic elements of every computer program are discussed. (JN)

Discusses four types of computer programs that can manipulate linguistic symbols with great facility. These programs deal with: (1) machine translation; (2) word processing; (3) question answering; and (4) adjuncts to electronic mail known as coordination systems. Also considers the future of computer software dealing with language. (JN)

Interactive computer graphics is fast becoming the standard medium of communication between computers and all kinds of users. Reasons for this trend, the technology of interactive graphics displays, software considerations, applications (including classroom and laboratory applications), and future developments are discussed. (JN)

Discusses ultrafast phenomena that may influence device performance and describes new experimental methods utilizing short optical pulses to investigate materials and device structures. (JN)

Discusses the nature of programing languages, considering the features of BASIC, LOGO, PASCAL, COBOL, FORTH, APL, and LISP. Also discusses machine/assembly codes, the operation of a compiler, and trends in the evolution of programing languages (including interest in notational systems called object-oriented languages). (JN)

A computer operating system spans multiple layers of complexity, from commands entered at a keyboard to the details of electronic switching. In addition, the system is organized as a hierarchy of abstractions. Various parts of such a system and system dynamics (using the Unix operating system as an example) are described. (JN)

This brief describes graduate enrollment increases in the science and engineering fields, especially in engineering and computer sciences. Graduate student enrollment is summarized by enrollment status, citizenship, race/ethnicity, and fields. (KHR)
