A simulation model for studying the needs for correctional institutions

A digital-computer simulation model of the incar ceration rates and characteristics of criminal offenders was developed and used to study the needs for developing new correctional institutions. The model gives insight into the snarls and pitfalls of the system and allows alternate plans to be studied prior to actual implementation. The data from an actual multicourt system are presented in detail.

A Software oriented Computer Science program

Many Computer Science programs are mainly concerned with hardware and software theory. Computer Software especially is studied with very little application. American Technological University has attempted to breach the gap in the area of qualified software computer science graduates by tailoring the courses to allow students to study or write, and/or modify operating systems. This is accomplished by selected course work and “hands on” use of the 370/145. Junior, senior and graduate level students are allowed to sign up for blocks of time between 10:00 p.m. and 6:00 a.m. Monday through Friday when available and on most week-ends. A description of courses, the philosophy of teaching, the computer facilities, and a critique of our former students is presented.

Computer science as a foreign language substitute

The world of today has a diversified opinion concerning the worth and value of the computer. For some it is a monster to be feared, while for others it is a friend to be respected. Two statements will probably best demonstrate these different points of view. Lewis Mumford has said, “Nothing that man created is outside his capacity to change, to mold, to supplant, or to destroy. His machines are not more sacred or substantial than the dreams from which they originated.”

Evaluation of efficiency in a virtual memory environment

The development of elaborate supervisory systems for the modern day computer has dictated a need for a means of evaluating the efficiency of the computing system under normal operating conditions. This paper defines a set of synthetic job streams which can be used to evaluate the performance of virtual memory computing systems under batch program conditions. An illustration of the use of these synthetic streams is presented in an empirical search for the optimum batch limit of a specific example of a virtual memory computer system. Limited tests are also presented to support the results of this study.

A computerized health and nutrition assessment for school children

A comprehensive school health and nutrition program requires an interdisciplinary (team) approach to the delivery of services. To achieve this, a management system requiring participation of project components (mental, physical, educational, and nutritional) was implemented. The project required a comprehensive effort to assess the students health status. The decisions were basically limited to set levels or values less than normal. This was accomplished by comparison of data collected with the charts shown in Tables 1 and 2 (all comparison charts are not shown in this paper). It is the intent of this health record to place emphasis on areas of weakness for individual students as well as strong areas.

The role of computer science minors in undergraduate and graduate curriculums

It has been estimated that over 200,000 computer related jobs went begging in the United States in 1974 because of lack of qualified college graduates. Both Industry and Government are concerned about the lack of practical knowledge of college graduates. A national survey estimated that 95 percent of all undergraduate business majors had to be re-educated to the tune of

8,000 each on the average before they could be considered productive workers.

Simulation of commercial job stream in a multiprogramming scheduling environment

The accelerated accumulation of knowledge in recent years has illustrated graphically the value of developing human resources to their most usable form at an early point in each persons life span. Not only is this early development important to the continued growth of the nation but to the expanded life style and earned human dignity of each individual. Traditional education techniques have fallen short in this regard. Students have graduated from two year colleges, four year colleges, and graduate programs with ill defined capabilities directed toward no specific area within the world of work. Human resource capability loss has been staggering and in some instances, irreparable harm has resulted. In recognizing the problem and its wide-spread ramifications the Federal Government as well as State Governments have developed programs of career education for junior and four year colleges. Central Texas College in Killeen, Texas, is one of these development areas and provides an excellent two year associate degree in Computer Science. The curriculum and text requirements are presented in this paper.

A Pageable Memory Dictionary Information Retrieval System

The selection of computing equipment for application to commercial uses is a giant financial step for any company. Justification may sometimes be only the salesmanship of a particular vendor. Many times this has provided a disasterous effect because the machine in reality was unable to handle a specific job stream efficiently. It is far too expensive to try all possible combinations of job stream inputs to check a computers ability to handle each. Simulation provides a feasible method for trying all combinations of job stream on a particular machine before it is purchased or leased. The purpose of this simulation model was to generate job streams consisting of programs possessing characteristics which are typical of those programs existing in a varied business type application. If specific job stream input is known then the model is able to give a “feel” for plausibility of a particular machine without running the risk of purchasing the machine in doubt.

HOMLIST: a computerized real estate information retrieval system

A Pageable Memory Dictionary Information Retrieval System (PMD) was designed and implemented using a time-sharing operating system under the virtual memory concept. The PMD system utilizes three separate data bases which may be used independently or in conjunction with each other, depending on the search parameters entered into the system. The PMD system was designed to use the ACM Computer Review Number and Category Number in addition to the normal search parameters. The test data base was formulated using information from the ACM Computing Reviews. The presentation includes the design criteria, file descriptions, retrieval techniques, examples of the retrieval process and their associated timings, and conclusions.
