Describes an inexpensive, simple, microprocessor-based instrument which quickly and accurately measures and displays the indicated power and the pressure-volume indicator diagram of a reciprocating compressor or internal combustion engine. Hardware requirements, software considerations, and the instrument's educational value are discussed. (JN)

Presents a programing subroutine which will create a graphical plot that occupies any number of columns specified by user and will run with versions of BASIC programming language. Illustrations of the subroutine's ability to operate successfully for three possibilities (negative values, positive values, and both positive and negative values) are…

Outlines a sequence used to prepare and to administer examinations by computer. The sequence, based on programs described in an earlier issue of "The Physiologist," is presented under four headings: preliminary steps; taking the quiz; grading the quiz; and flexible options. Information on obtaining the programs is included. (JN)

A computer program for office layout design written for an Apple computer is discussed. Through its application, the user is freed from the tedious tasks of template manipulation and manual drawing and can therefore concentrate on the creative part of the design process. (Author/JN)

Describes an interactive, screen-oriented, BASIC computer program for an IBM PC microcomputer with graphics capability. The program (which uses about 34K RAM and utilizes a menu format) represents a general method for calculating thermodynamic properties of chemical reactions from thermal data for reactants and products. (JN)

Courses for a computer technology program are listed. Hardware purchases necessary to use a mainframe computer in a single-user environment in a computer organization course is described, and sample runs from three programs are included. (MNS)

Explains how a microcomputer and a word processor can be utilized to keep teachers' records and presents a brief BASIC word processing program called SCRIPSIT to show how grades can be calculated from those records. Possible program modifications and how to construct the SCRIPSIT file are discussed. (MBR)

Describes microcomputer-based automation for library applications, noting use of inexpensive (sometimes free) existing programs and software such as dBase II to write or modify programs to meet specific needs. Programs written for the IBM PC-XT to produce serials lists and analyze serials collections are included. Five references are listed. (EJS)

Suggestions are provided on diskette care, software worth seeing, teaching that computers can't do everything, and a debugging activity. (MNS)

A Commodore-64 microcomputer was used to develop a system which is useful for a variety of teaching laboratory and real time control applications. Hardware and software requirements and examples of experimental work with the system are provided. (JN)

Discusses how the Minnesota Cooperative Extension Service has developed computer programs and used computer technology to improve and expand its educational efforts in food and nutrition. Difficulties encountered in program development are indicated. (BC)

Discusses the development of an instrument to assist educators in evaluating software and to aid them in developing useful software for nutrition education and nutrient analysis purposes. The complete survey instrument is included. (JN)

Provides a step-by-step approach for administrators to follow when becoming aquainted with their first computer. (MD)

A one-month graduate course on time series analysis is offered in the department of chemical engineering at the University of Queensland (Australia). Describes the course, which is based on an interactive graphics time series identification and modelling computer package (TSIM). Also describes time-series analysis procedure and the TSIM package.…

Discusses the hardware and software necessary to generate charts and graphs to illustrate numeric data using a microcomputer. The manufacturer, price, operating system, memory requirements, and types of graphs they can produce are given for nine graphics software packages and seven inexpensive plotters. (MBR)
