This paper presents a study on the effects of various data compression methods from the viewpoint of central computer to terminal communications on a large graphics oriented timesharing system, PLATO IV. The desired goal is to increase terminal display speed without significant increase in the transmission error rates. While the major emphasis in…

Current plotting techniques offer new ways for decisionmakers to look at data via graphs, pictures, maps, and 3-D models. (Author)

This report consists of four parts. The first part is a non-technical summary of the basic problem and an attempted solution. The second part is a technical review of the literature and a description of the basic algorithm used in the solution. The third part describes the use of the Sociogram System. The fourth part describes the use of CHAIN, a…

The computer-based system for routing school buses in rural areas which is discussed minimizes both transportation costs and the average student ride time. Route generation methodology is described and a flowchart of the algorithm is included. (Author/JJD)

An effort to construct a model of the thermal properties of materials based on theoretical thermo-electromagnetic models, to construct a data base of the dense cultural hospital scene according to Defense Mapping Agency Aerospace Center (DMAAC) specifications, and to design and implement a program to evaluate the tonal model and generate imagery…

This research report is part of the Water Pollution Control Research Series which describes the results and progress in the control and abatement of pollution in our nation's waters. The River Basin Model described is a computer-assisted decision-making tool in which a number of computer programs simulate major processes related to water use that…

This study presents a review of selection factors for the seven major general-purpose programming languages: Ada, BASIC, C, COBOL, FORTRAN, PASCAL, and PL/I. The factors covered include not only the logical operations within each language, but also the advantages and disadvantages stemming from the current computing environment, e.g., software…

Recommends the use of computer graphics for making smart and quick decisions and reducing costs. Discusses the advantage of having user-friendly graphics, the importance of using a proper format, the basic steps for generating computer graphics, and the need to be aware of possible abuse or misuse of graphics.

This catalog was prepared for the Department of Vocational Career Development of Georgia State University as a supplementary manual to its recently developed catalog of courses. It is a survey of available literature on a wide variety of technical subjects formerly not included in traditional vocational or technical education in Georgia. Included…

A rationale for the use of gaming and simulation for instructional purposes is developed in the introduction to this paper. The major portion of the text is comprised of several models of computer programs for economics instruction. (SHM)

The PLATO IV computer-based educational system contains its own communications hardware and software for operating plasma-panel graphics terminals. Key echoing is performed by the central processing unit: every key pressed at a terminal passes through the entire system before anything appears on the terminal's screen. Each terminal is guaranteed…

A detailed account is given in this paper of the procedures and the equipment used in producing six computer-animated instructional movies. First, the sequence of events were described in a script, which, together with the analytical expressions that were dealt with, formed the basis of a program. Then, the program was run on a computer and the…

This information processing curriculum was developed to provide business education instructors in Illinois with a useful guide for relating important new technological advances to the vocational classroom. The competency-based learning activity guides are written to be used with computer hardware and software available at the secondary and…

This document contains a composite of learning activities for use in a secondary-level course in business computer applications. The collection is unique in that the individual learning activities constituting it have each been tailored to one or more of the diverse learning styles possessed by individual students. The activities are grouped into…

This document consists of a curriculum guide combined with separately published "Simulations" and "Test Bank" volumes designed to support instructors using the curriculum guide. The curriculum guide for "business computer applications I" provides office education instructors with detailed units of instruction…
