Incremental Analysis Of Programs, Vida Ghodssi

Retrospective Theses and Dissertations

Algorithms used to determine the control and data flow properties of computer programs are generally designed for one-time analysis of an entire new input. Application of such algorithms when the input is only slightly modified results in an inefficient system. In this theses a set of incremental update algorithms are presented for data flow analysis. These algorithms update the solution from a previous analysis to reflect changes in the program. Thus, extensive reanalysis to reflect changes in the program. Thus, extensive reanalysis of programs after each program modification can be avoided. The incremental update algorithms presented for global flow analysis …

The Influence Of Induced Self-Awareness On Sex-Typed Behavior, Kevin J. Lopyan

Retrospective Theses and Dissertations

The purpose of the experiment was to contrast a person's adherence to private and public standards of conduct under varying situational settings. Prior to the experimental session female undergraduate students filled out a questionnaire that asked about their own attitudes towards exercising. Two types of subjects were brought into the laboratory: those who privately favored exercise but believed that others would not approve of their exercise (henceforth referred to as "positive discrepancy" subjects), and those who privately did not favor exercise, but anticipated approval for it (henceforth referred to as "negative discrepancy" subjects). The laboratory setting involved pedaling a stationary …

Mathematical Model For Estimating Transient Pressure Surges In Cryogenic Liquid-Vapor Systems, Philippe Pfister

Retrospective Theses and Dissertations

Numerical treatments have become the most accurate methods for transient liquid flows analysis. Based on a computer code provided by NASA/KSC, this paper presents two simulations of cryogenic transfer systems. Experimental data originated from the Space Shuttle Liquid Oxygen Servicing were obtained during drain flows. Two sets of data (pressure at various locations versus time) corresponding to a drain stop and a drain initiation were used for a comparison with the predicted pressures. The first test case was a single-phase flow whereas the second one was associated with liquid-column separation and vapor cavity collapse. Major modifications were made to the …

The Simulation And Water Quality Characterization Of A Coal Slurry Involving Eastern Coal, Michael R. Todd

Retrospective Theses and Dissertations

The water quality characteristics of a coal slurry were found to vary widely, depending upon the coal used and the use of a corrosion inhibitor. The coal-water interactions were evaluated in a pilot-plant closed-loop coal slurry pipeline. Pulverized coal from eastern Kentucky and tap water were slurred and pumped through a 40 foot (12.2 m) pipe loop for ten days. Slurry samples were collected at 3 hours, 7 hours, 1 day, 2 days, 4 days, 7 days and 10 days from the start of a run. The samples were filtered and analyzed for 29 water quality parameters, including 15 metals. …

Diode Terminators For Reducing Line Mismatch And Crosstalk Transients On Pulsed Lines, Kieway Hwang

Retrospective Theses and Dissertations

Microprocessor techniques are always developed with the purpose of achieving greater data capacity per unit time. There are many different types of cables on the market which can be used in connecting the digital processing system. No matter what kind of material the cable is made of, the characteristic impedance mismatch and crosstalk from the neighboring lines could generate the noise to the line itself. Therefore, it is necessary to reduce the noise, especially for the high frequency data transmission bus. This report presents a simulation of two long distance transmission buses and reducing the noise by diode terminators.

Low Cost Neutron Detector, Sebastian K. Namukolo

Retrospective Theses and Dissertations

Neutron bombardment of bipolar transistors creates cluster defects in semiconductor material. The clusters are small volumes of semiconductor material containing several hundred atoms displaced from their proper lattice sites owing to collision processes. They act as recombination centers in transistor bases, reducing minority carrier lifetime and consequently reducing transistor current gain. The damage is permanent to the semiconductor device and can only be corrected by thermally annealing the transistor. Copious test data available on bipolar transistors d.c. gain (h_FE) response to incident fast neutron fluences confirm their mathematically derivable functional relationships. This report develops a neutron fluence detector …

Modal Analysis By State Space Approach In Frequency Domain, Feliciano Feijo

Retrospective Theses and Dissertations

This report tests a new procedure to identify the eigenvalue problem matrix "A" by utilizing the frequency response of a system in state-space for a given sinusoidal forcing input. Two sample identification tests are performed and a detailed explanation of both cases is presented. The method proved to be correct and the results obtained were accurate in both cases. A random error was then added to both sample tests in order to simulate real measuring conditions. Results indicate that it is more difficult to identify the "A" matrix of an undamped system. The error in the system must be very …

The Technical And Economic Feasibility Of Producing Methane From Biomass Using A Leaching-Bed/Packed-Bed Conversion Process, Steven W. Hinton

Retrospective Theses and Dissertations

The economic feasibility and energy effectiveness of producing pipeline quality methane gas from biomass was assessed for a new and totally unproven process. The biomass feedstock considered was the common aquatic weed water hyacinth and a novel active boom-winch harvesting system is proposed for its collection. The conversion process analyzed is a two stage biological process which utilizes a leaching-bed for the production of volatile acids and a packed-bed for the production of methane gas. In order to determine the feasibility of the proposed process equipment requirements, capital costs and operating/maintenance costs were developed for three system sizes. This data …

Digital Communications System Evaluation: Design Developments In Pseudorandom Sequence Usage, Signal Conditioning And Timing Regeneration, Barry Lane

Retrospective Theses and Dissertations

The aim of this paper is to develop a series of designs which allow evaluation of several digital communication system design concepts. Circuits were developed and tested which deal with three central areas of concern in digital communication networks. They include random signal generation and detection, signal conditioning, and digital timing extraction. A pseudorandom sequence generator and correlator design form the basic digital channel. Bi-phase transmission coding and digital timing regeneration were later added to the initial channel. System performance was confirmed by inserting errors and measuring error rate.

Spacially Sampled Multi-Aperture Optical System For Robot Vision, Ali R. Baradar

Retrospective Theses and Dissertations

One of the solutions to the world's industrial and economic recovery and survivability is "Flexible Automation," wherein vision is the key to its cost-effective flexibility. Vision gives the robot a measure of environmental intelligence. The majority of present vision systems are patterned after the human eye, but this is not a requirement. It has been shown that the multi-aperture insect eye cannot image an object. The physiology of an insect eye is fundamentally different than that of the human eye in that it is not binocular by multioccular in nature. In order to study multi-aperture optics and indirectly the functioning …
