The Effects Of Altered Traffic Signs Upon Vehicular Driving Modes And Consequent Fuel Conservation And Environmental Benefits, As Measured By Vehicular Noise-Imprints, Mark Daniel Pfarrer
The Effects Of Altered Traffic Signs Upon Vehicular Driving Modes And Consequent Fuel Conservation And Environmental Benefits, As Measured By Vehicular Noise-Imprints, Mark Daniel Pfarrer
Retrospective Theses and Dissertations
The hypothesis is that the recorded noise-imprints of a vehicle at an intersection can be used to identify and accurately time the driving modes of deceleration, idle, slow cruise, and acceleration. This is proven by analyzing and comparing noise-imprints of vehicles at an uncontrolled intersection marked first with a "stop" sign, and then by a "yield" and an experimental "dead slow" sign. By relating the duration of each driving mode to known relations, the overall efficiency of an intersection can be characterized. A new technique for studying various types of traffic conditions at intersections is the result. Initial noise-imprint analysis …

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

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