A Report on Control of Access to Stored Information in a Computer Utility

Description: Time-sharing computer systems permit large numbers of users to operate on common sets of data and programs. Since certain parts of these computer resources may be sensitive or proprietary, there exists the risks that information belonging to one user, may, contrary to his intent, become available to other users, and there is the additional risk that outside agencies may infiltrate the system and obtain information. The question naturally arises of protecting one user's stored program and data a… more

A Method for Applying Scientific Subroutine Package in Microprocessor

Description: The scientific subroutine package is one of the most important parts of the software for the scientific industry. By now, most big computers have scientific packages, but applying such a software package in microprocessors requires consideration of the microprocessor's facilities, such as limited main memory, slow execution time, and only a few small registers. In any scientific package, the trigonometric functions are the ones more widely used. This paper discusses a method for implementing se… more

Computer Analysis of Amino Acid Chromatography

Description: The problem with which this research was done was that of applying the IBM360 computer to the analysis of waveforms from a Beckman model 120C liquid chromatograph. Software to interpret these waveforms was written in the PLl language. For a control run, input to the computer consisted of a digital tape containing the raw results of the chromatograph run. Output consisted of several graphs and charts giving the results of the analysis. In addition, punched output was provided which gave the name… more

A Top-Down Structured Programming Technique for Mini-Computers

Description: This paper reviews numerous theoretical results on control structures and demonstrates their practical examples. This study deals with the design of run-time support routines by using top-down structured programming technique. A number of examples are given as illustration of this method. In conclusion, structured programming has proved to be an important methodology for systematic program design and development.

Initial Research for the Development or Purchase of a Computerized Synthesizer For Use as a Composer's Aid

Description: The author's primary goal is to begin research leading ot the attainment of a low cost computer/music system which will allow the composer to write polyphonic music of up to eight voices into a computer through a terminal, and have the music played back by means of computer synthesized sound or by means of a conventional synthesizer controlled by a computer via digital-to-analog converters. The goal system will allow the composer to retreat and hear his product objectively as the painter steps … more
