Optimization of the GDP Equation

Economics are now using Engineering Mechanics to solve Economic problems. In this paper, we use Astrotheology Mathematics to optimize the GDP equation. This Econphyscis can be used to program a computer to create a real-time computer program to solve unknown variable, such as consumption, in the broad economy.

The development of the ERRC food process simulator

A simulator was developed for food processing. The simulator links mathematical models for the variouis unit operations encountered in a food process. The models are based on theoretical considerations or in many cases are semi-empirical and developed using laboratory and pilot plant data. The program was written in Fortran using potato processing as a prototype. Models for such critical unit operations as hot water blanching, water cooling, steam cooking, drum drying, and deep fat frying were developed. The models were also adapted for use in real-time computer programs to control processed potato color and degree of cook of potatoes. This paper documents the integration and validation of the models developed.

Computer analysis of EEG, EOG, and NPT activity during sleep

Enhancements to DELREM, a real-time computer program which concurrently analyzes EEG and EOG activity, are presented. These include the program's ability to monitor nocturnal penile turnescence (NPT) during a sleep recording, and the use of a standard calibration signal for time synchronization and adjustment to differences in tape recorder amplification and speed settings is used. Some of the advantages of using DELREM are discussed.

On-Line Monitoring of MWD in a Batch Polymerization Reactor by Size Exclusion Chromatography

Abstract A novel highly automated SEC system has been developed for online measurement of MWD in a batch solution polymerization reactor. The system includes a liquid exclusion chromatograph, an automatic sampling system, a programmable microprocessor based sequence timer and a process computer. Two main real-time computer programs have been developed to supervise the automatic collection (SEC-Data Acquisition Program) and interprepation (SEC-Data Interprepation Program) of SEC data. Experimental results show that the new system can provide reliable on-line measurements of number average and weight average molecular weights of a sample during the course of polymerization.

Core resource management for large real-time computer program development

Large-scale real-time computer programs designed to drive major military systems regularly invoke astronomical requirements for core memory in their embedded computers. On the other hand, space and weight constraints in ships, aircraft, and land-based mobile units exert a strong counterforce to restrict the number and size of the computers. These contrasting demands underscore the critical need for aggressive control of core resources throughout the computer program development cycle for major weapon systems. This paper describes a n approach to core resource management that has been applied successfully on a typical major system, the Navy's AEGIS Ship Combat System. The core management process begins in the system definition stage with estimates of computer program size based on system performance requirements, program architecture, and computer capability, plus knowledge of program requirements of similar operational systems. The estimating process iterates throughout development, and includes a budget of core reserves for anticipated growth. Stringent monitoring and control, invoked during the design and test stages, include both formal milestone reviews and frequent internal status reviews. Because the cost of program development invariably becomes a critical issue, a special algorithm was developed as a means of predicting and controlling development costs.

A Real-Time Line Reclosing Analysis Technique Analysis Using Distribution Factors

This paper describes a recently developed real-time computer program at the control center of the Pennsylvania-New Jersey-Maryland Inter- connection (PJM) designed to determine the impact of returning a transmission facility to service. The method is unique in that it incorporates the use of only megawatt flows and distribution factors. The paper discusses the solution algorithm and the applicability of its use in present and future system monitoring analyses.

An Integrated Real-Time Control Scheme For HVdc Multiterminal Systems

A real-time computer program for operation and control of multiterminal HVdc transmission systems is presented. The program is validated by tests using a dc system simulator connected to a minicomputer.

Theoretical and Practical Comparison between Two Minute Doppler and Short Doppler Satellite Position Fix Accuracy

This paper provides data to aid the user or prospective user of the Navy Navigation Satellite System to better understand what results can be expected from either a two-minute doppler position fix program or a short doppler position fix program. Brief summaries of satellite theory and the mathematical and mechanizational differences between two minute and short doppler computations are presented. A description of a computer program capable of computing both two-minute doppler and short doppler position fixes is given. Data is presented which has been computed using the actual real-time computer program. Position fix results from the two different doppler methods, obtained from the same satellite passes, are shown. Conclusions are drawn from these results as to the inherent accuracies of the two methods and in what circumstances one method or the other is more advantageous.

GPC calibration for polymers of unknown composition and structure using a real‐time computer

AbstractA computer technique ultimately yielding, from GPC data, both differential and integral molecular weight distributions of macromolecular products with unknown composition and structure has been worked out, based on a “universal” calibration method previously proposed by other authors to calculate average molecular weights. The technique involves as sole assumption the validity of the “universal” calibration for the kind of sample under investigation. The GPC output data are handled through a realtime computer program and punched on paper tape. Together with two experimental parameters of the polymer (average molecular weights, limiting flow number) and the “universal” calibration of the columns set, the tape is used as input for the off‐line programming. Examples are presented, showing the accuracy which can be expected.
