A Simulator For The Motorola M6800 Microprocessor, Carolyn Elizabeth Jordan

Retrospective Theses and Dissertations

The Motorola Company has developed a microprocessor called the M6800 Microprocessor. While the microprocessor is being configured, it is general practice to develop the software at the same time. This is where simulation of the proposed hardware operation can become very important to the success of the design effort. The simulator duplicates the microprocessor execution of machine language instructions on another computer. The simulator discussed in this paper is denoted the SIM6800. The purpose of this paper is to describe the structure, coding, and execution of the SIM6800 simulator. A User's Guide and sample program have been included.

Mass Loadings Of Selected Water Quality Parameters For The State Of Florida, Charles D. Miller

Retrospective Theses and Dissertations

The mass loadings of pollutants common in surface waters result from the discharges of many different sources. In the last few years it has been noted that nonpoint sources contribute more pollutants than point sources. This is because in many cases the point source discharges have been, by law, reduced drastically. In the State of Florida many water quality parameters were examined to estimate the mass loadings in streams related to, drainage area, average flow, land use, soil type and management practices. A total of sixteen streams were examined. The information was first calculated for mass loadings as a function …

Multicoupled Bandpass Filter Design Using A Multiple Feedback Configuration, Robert J. Martin

Retrospective Theses and Dissertations

In this paper, two methods for the design of active analog feedback bandpass filter pairs are examined. A third method is presented that does not use extra amplifiers for summation nor multicoupling. This third method uses identical bandpass amplifies and employs resistor summing to provide multicoupling. The name of this configuration is the "Dual Amplifier Bandpass Filter Employing Resistor Summing" (DABFERS). This configuration is economically attractive, has low sensitivity and better phase lag characteristics. In addition, third order prototypes are examined and a solution method for higher order prototypes is suggested.

A Computer Simulation Of A Weapons Fire Simulator Modeled By Sceptre As An Optical Communication Channel, John James Cormack

Retrospective Theses and Dissertations

This paper presents a method of simulating various noise sources in a Weapons Fire Simulator System which has been modeled as an Optical Communication Channel. This Weapons Fire Simulator System is composed of laser transmitters mounted on weapons that fire blank cartridges, and laser receivers mounted on targets. The laser transmitter sends out 'kill' beam pulses to the target whenever blank cartridges are fired. Detection of these pulses at the target signifies a 'hit'. The entire system along with the optical communication channel is simulated in a general purpose computer program called SCEPTRE. This analysis package is an efficient means …

Analytical And Experimental Investigation Of Thermosyphon Solar Hot Water Systems, William E. Clark

Retrospective Theses and Dissertations

A computer simulation of a thermosyphon system allowing load drawoff and non-ideal weather conditions has been developed. The model is restricted to the more common single cover, flat plate collector system. Using an analysis based on the present literature, this model calculates the energy absorbed by the collector, the temperature distribution through the system, and the corresponding flow rate. Experimental data for a non-ideal day is compared to the computer simulation. Results of this comparison indicate that the desired parameters, flow rate, collector inlet and outlet temperatures, and the mean tank temperature can be predicted by this model to within …

Torque-Speed Linearization Of A D.C. Servo System, Nicholas A. Mantello

Retrospective Theses and Dissertations

In early 1973 Professor Fred O. Simons Jr., of Florida Technological University, suggested the topic for this research report. During control engineering discussions, it was proposed that a D.C. Shunt Motor could be constrained to perform in an idealized sense for the static case. The purpose of this report is to provide a reasonably comprehensive examination of a control which linearizes the torque-speed relationship of a dc servo system. The fundamental goal is to determine a control which linearizes the torque-speed output relation of a system, in which a dc shunt motor is under basic armature control. Consequently, the emphasis …

A Comparative Study Of Forecasting Techniques For The Us Air Force Medical Material Management System, Phillip John Van Ess

Retrospective Theses and Dissertations

A computer simulation experiment was conducted to evaluate and compare five individual forecasting models across nine different demand patterns. The models were based on the Medical Materiel Management System used by the US Air Force hospitals. Results indicated the best model varied depending on the demand pattern, the safety stock level, the noise level of the demand pattern, and the measure of forecast error. Across all demand patterns, exponential smoothing and 12-month moving average were best for the short term forecast used by the system, regardless of noise level in the demand patterns. Analysis of models within a single demand …

An Industrial Wastewater Treatment Review For The Textile And Pulp And Paper Industries Of Srilanka, Kolonne A. Wijeratne

Retrospective Theses and Dissertations

A legislative authority empowered to protect Srilanka's environment, operating similarly to the Environmental Protection Agency of the U.S., is needed, along with wastewater treatment. Wastewater parameters of importance in treatment are BOD, COD, total suspended solids, settleable solids, pH, colour, turbidity, ammonia or nitrate nitrogen, heavy metals, sulfides, phosphates, and phenols. Methods of industrial waste treatment vary depending on the climatic conditions, the industry, raw materials, and process adopted. Textile and pulp and paper industries exist in Srilanka and have very high pollution potential. Methods of treatment to finally generate reasonably good quality effluent are available. Processing of effluents from …

Sample Design For Electricity Pricing Experiments: Anticipated Precision For A Time-Of-Day Pricing Experiment, Dennis J. Aigner

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The primary goal of a pricing experiment is basically the same as that for an experiment in direct load control: To discover the effects of time-of-day pricing on the shape of the daily load curve for a particular customer or class of customers. For the pricing experiment, it is also of interest to know how those effects are related to the pricing structure itself.

In this paper, we consider two alternative models of kwh consumption for residential customers as the basis for calculating an optimal experimental design, and compare them in terms of the levels of precision of estimation (for …

Carbon Removal Of Organohalides In Drinking Water, William Ray Mccurley

Retrospective Theses and Dissertations

Drinking water samples provided by Orlando Utilities from various locations and from Florida Technological University were analyzed for organohalides. Compounds tentatively identified were 0.0024 mg/l DDT, 0.003 mg/l phosdrin, 0.00036 mg/l BHC, and 0.000095 mg/l endosulfan. These concentrations are well below recommended limits for drinking water. Two water samples were mixed with 10 mg/l of 20-40 mesh granular activated carbon, agitated for 2 minutes and then allowed to settle in the flask for 45 minutes. A reduction in the organohalide concentration varied from 25 to 98 percent of the original concentration. Also, a solution of seven common pesticides of 0.1 …

Dynamic And Stability Characteristics Of An Articulated Frame Railway Passenger Truck, David Kenneth Platner

Retrospective Theses and Dissertations

Mass transit vehicles in formal rail service frequently attain speeds which can excited carbody oscillations (primary hunting), as well as sustained lateral oscillations of the trucks (secondary hunting). The carbody motions have been shown to generate passenger discomfort and sustained truck hunting can lead to derailment. This thesis developed approximate equations which predict the carbody hunting frequencies, as well as the hunting speed of an articulated frame truck. The linear equations of motion are derived from a simplified model of a railway vehicle. A comparison indicates the results obtained using the approximate truck hunting equation presented here are within ten …
