In educational technology and learning sciences, there are multiple uses for a predictive model of whether a student will perform a task correctly or not. For example, an intelligent tutoring system may use such a model to estimate whether or not a student has mastered a skill. We analyze the significance of data recency in making such…

Hamilton, Jr.); (2) Semantic Annotation of Stock Photography for CBIR Using MPEG-7 standards (R. Balasubramani and V. Kannan); (3) An Experimental Study…

An analysis to ascertain which electronic data processing (EDP) systems are most flexible in processing wide ranges of volumes efficiently. A simulation model of the job environment of three common EDP systems provides information on the shape of their cost functions in the neighborhood of optimality. (Author/LS)

SNAP/SHOT (System Network Analysis Program-Simulated Host Overview Technique) is a discrete simulation of a network and/or host model available through IBM at the Raleigh System Center. The simulator provides an analysis of a total IBM Communications System. Input data must be obtained from RMF, SMF, and the CICS Analyzer to determine the existing…

Comprehensive Analytical Methods for Planning in University Systems (CAMPUS) and Computerized Analysis Adapting the Techniques of Simulation to Colleges of Applied Arts and Technology (CAATS)-2 are combined to represent a computer based information and planning system. This system is designed to help the community colleges of Ontario gain the…

The design of a database interface, the different types of decisions supported, the nature and applications of the system outputs, and continuing work on extending the system are described. The system was designed to forecast the enrollment for Guilford College. (Author/MLW)

Beginning January 1, 1969, Systems Research Group (SRG) undertook a project to develop operational cost simulation models of three of the colleges of applied arts and technology in Ontario. These models, and the data needed to feed them, have been developed and are now operating. SRG describes their progress to date and identifies the remaining…

A scheme which classifies the instructional applications of computers is designed to overcome the confusion created by the imprecision and equivocation associated with computer terminology. The classification is restricted to instructional applications, allows that some applications could apply to more than one category, and reflects a continuum…

The community college president's role in facilitating institutional computer utilization is explored, and recommendations are made for his/her behavior and priorities in connection with educational concerns, institutional concerns, and statewide concerns. Typical institutional organizational arrangements regarding campus computers, research,…

This study sought to develop a predictive model for use by educational decision makers in establishing junior colleges, as more needs and costs become known and more precise bases for judgment are needed. Decision-making models were considered suitable for this study. Correspondence with officials produced a valid list of criteria and identified…

Computer-based information systems have evolved from emphasizing data processing to providing full and flexible support for management. They have moved from providing mere data to providing a medium for representing knowledge wherein managers can analyze data, formulate ideas, structure arguments, and building models. (Author/MLW)

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…

PLANTRAN II is a system of computer software designed to assist educational administrators in their planning and analysis activities. The unique feature of PLANTRAN II is that it requires no computer programing experience or expertise. Users with technical background have found PLANTRAN II helpful in their analyses without reducing the complexity…

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…
