A Comparative Limnological Study Of Three East Central Illinois Farm Ponds, Charles W. Furrey

Masters Theses

A comparative limnological study was conducted at three east central Illinois farm ponds between March 15 and September 18, 1970, to determine the incidence of nitrogen and phosphorus in the ponds resulting from agricultural sources. All ponds had corn, soybean, winter wheat cropping systems on their watersheds. Corn accounted for the greatest fertilizer application. One pond had significant numbers of livestock on its watershed that contributed high amounts of nitrogen and phosphorus to its waters. Limnological parameters measured at the surface, mid depth, and bottom of a ten foot water column in each pond were water temperature, dissolved oxygen, carbon …

The Integrated Planning Method Of Project Planning, Development And Implementation, Joseph Frank Lynch

Masters Theses

"Present comprehensive planning endeavors lack a consistent methodology which will produce realistic, useable results. The validity of this statement should be obvious after one has read Miller's "Evaluation of City and Region Planning Techniques." This paper contains a methodology, "The Integrated Planning Method," which will go a long way toward correcting this gross inadequacy that planners presently encounter in directing planning efforts. Two government developed planning and analysis procedures that, up until this time have been applied almost exclusively to hardware systems, have been combined into one integrated planning methodology that will provide not only meaningful and rigorous definition and …

Intrinsic Viscosities Of Linear Polyethylene, Joseph Shing Chiang

Masters Theses

"Intrinsic viscosity measurements were performed on linear polyethylene (Marlex 6009) in decalin at 135ºC and in diphenyl ether at 163.9ºC. Molecular weights ranging from 3x10³ to 35x10⁴ were studied. It was found that for linear polyethylene of molecular weight up to 35x10⁴, the tedious intrinsic viscosity measurement could be replaced by inherent viscosity measurement at a concentration of 0.1 grams per deciliter. The effect of shear on viscosities measured in decalin increased as the molecular weight of the sample increased. The shear rate effects on intrinsic viscosities were negligible. On the other hand, the shear rate effect on the Huggins' …

An Investigation Of Stress In The Monowall Construction System Subjected To Racking Loads, Louis Alex Kuhlmann

Masters Theses

"Several methods of analysis were employed to investigate the stress conditions of concrete block built in the MONOWALL Construction System, when subjected to racking loads. MONOWALL is a technique of assembling blocks with adhesive rather than conventional portland cement mortar. The analyses used in this study included strain gages on full-scale walls, photoelastic models, and a mathematical solution. Each method of analysis is reported separately in detail and the results compared to each other"--Abstract, page ii.

A Digital Computer Simulation Of A Rural Two-Lane Highway, D. Jay Frankenfield

Masters Theses

"The traffic flow model developed in this study is a digital computer simulation utilizing the technique of periodic scanning to move the vehicles through a series of unit blocks. The model simulates traffic flow on a rural two-lane highway by assuming a straight and level road and incorporating sight distance restrictions and no-passing zones to simulate the effect of limited sight distance. By utilizing various "passing rules" to initiate the passing maneuver, three general topics were investigated. This study investigated the use of 1000 ADT as a criterion for yellow line striping no-passing by using the computer simulation to determine …

An Investigation Of A Bistable Oscillator Used In A Phase Modulated Control Circuit, Yu-Fang Yen

Masters Theses

"A primary component in the investigation of phase modulated control systems is bistable oscillator which converts a constant oscillation signal to control the system. The oscillator is feedback type that utilizes a feedback capacitance and resistance in each feedback path to change its frequency. The theoretical behavior of bistable oscillator was investigated and the non-dimensional results were set for convenience in determining the oscillation period. The control circuit which based on the oscillator was also presented a form of suitable circuit for direct application to practical control problems"--Abstract, page ii.

Distribution, Petrology, And Environment Of The St. Louis-Ste. Genevieve Transition Zone In Missouri, Donald Howerton Fielding

Masters Theses

"In eastern Missouri, southeastern Iowa, and western Illinois - a transition zone, a body of rock consisting of several lithosomes which has a geographic extent measured in scores to hundreds of miles and which lies between a single overlying formation and a single underlying formation and which has lithologic and/or paleontologic properties common to both the overlying and the underlying formations, was found to exist between the St. Louis and the Ste. Genevieve formations. This transition zone is called the St. Louis-Ste. Genevieve Transition Zone, and is shown to possibly be due to continuous deposition between these two times and …

A Driver-Assisting Control System, Roger Allen Hayes

Masters Theses

"The material presented here explains the electronics of a magnetic guidance control system. The system is based on magnets embedded in the center of the roadway. If a vehicle passes near a magnet, fluxgate magnetometers sense the presence of the magnets and guidance pulses are developed and processed. The end result is a visual output which indicates the direction the driver must steer the vehicle for proper positioning on the roadway. The paper presents a solution to the detection problem caused by the sensor output being a function of the earth's field as well as the field of the guidance …

Anodic Oxidation Of Ethylenediaminetetraacetic Acid On Pt In Acid Sulfate Solutions, Howard Ho-Wei Jiang

Masters Theses

"The anodic oxidation of EDTA was studied in acid sulfate solutions on platinized-Pt at 25ºC. Polarization relationships were obtained for the EDTA concentration range 3. 42 x 10⁻⁵ to 3. 42 x 10⁻³ M and pH range 0. 35 to 3. 80. Numerous reaction products were identified that indicated a sequential removal of acetate groups from the EDTA, each by an initial decarboxylation followed by a reverse Schiff-type reaction, that produced formaldehyde and the corresponding amine. A reaction sequence which correlated the experimental data involved Frumkin-type adsorption of the EDTA species through an unionized acetate group followed by a rate-determining …

An Energy Solution For Vibration Characteristics Of Free Thin Cylinders, Dale Elmer Leanhardt

Masters Theses

"In this report the flexural vibrations of the walls of free, thin, circular cylinders are considered. Theoretical expressions are developed for the natural frequencies by extending the approximate energy method of Arnold and Warburton to the free-free case. Furthermore, the developed expressions are shown to apply, as special cases, to the fixed-fixed and simply-supported cylinders analyzed by Arnold and Warburton. The energy solution for free-free cylinders is checked both experimentally using a 3500 pound-force, 5 to 2000 hertz, vibration exciter and numerically using the well documented SABOR IV-DYNAL finite element program. While the derived energy method accounts for any prescribed …

Calculation Of Eddy Current Loss Of A Disc, Kou Quen Chang

Masters Theses

"A method is presented to calculate the eddy current losses of a uniform disc with an opening in the center and excited by a circular current loopage First, the disc is subdivided into smaller concentric rings, then the self-inductances, the mutual inductances between these smaller rings, the mutual inductances between the excitation coil and the smaller rings, and the resistance of the rings are calculated. Next, the eddy current flowing in each ring is obtained by solving a complex matrix equation of the form [X] [I] = [V] where X is the impedance matrix, I is the eddy current matrix, …

Frequency Division Using Cascaded Phase-Locked Loops, Curtis B. Abshier

Masters Theses

"In many practical communication systems it is necessary to generate phase coherent subharmonics of an input tone. A useful system for accomplishing this task is a system of phase-locked loops in cascade. It is shown that when the feed-forward function is matched, the phase error of the second loop is zero. Analytical analysis and computer simulation prove that the minimum time to achieve phase-lock is obtained when the feed-forward function is matched. Under this condition, necessary design parameters are determined with ease"--Abstract, page i.
