Program Evaluation And Review Technique, Anthony Immaculate Agresta Jun 1962

Program Evaluation And Review Technique, Anthony Immaculate Agresta

Theses

The problem of planning, controling and evaluating complex projects both engineering and non-engineering has existed as long as the projects themselves. In the past the approach of management to this problem has been one which was based heavily on the use of historical information. There have been very few attempts to predict and control the occurrence of the objective event of these projects.

This thesis deals with a review of this problem and a new approach to the planning, control, and evaluation of these complex projects. This new approach is the Program Evaluation and Review Technique (PERT) which was developed …


Zirconium-Hafnium Equilibria, Edwin Otto Eisen Jun 1962

Zirconium-Hafnium Equilibria, Edwin Otto Eisen

Theses

Equilibria in the thiocyanate-methyl isobutyl ketone process for the separation of zirconium and hafnium were studied. The effects of average thiocyanate concentration, feed acidity, and feed zirconium concentration on the separation factor of hafnium and the distribution coefficients of zirconium and hafnium were investigated. The hafnium separation factor was significantly dependent on the feed acidity but only slightly affected by the average thiocyanate concentration. No conclusion was reached about the effect of the feed zirconium conoentration on the hafnium separation factor. The polymerization of thiocyanic acid was found to be strongly dependent on the average thiocyanate concentration.


An Evaluation Of Oxide Films Of Lead And Tellurium Prepared By Reactive Sputtering, Frank Groom Peters Jun 1962

An Evaluation Of Oxide Films Of Lead And Tellurium Prepared By Reactive Sputtering, Frank Groom Peters

Theses

Oxide films of lead, tellurium, and their alloys were deposited by reactive sputtering onto substrates and analyzed by X-ray emission spectrography. The sputtering process involved the bombardment of a metallic cathode with positive ions in an atmosphere containing oxygen. The preparation and analysis of these films are described. The unstrained, homogeneous films have good adherence to the substrate and may be prepared to arbitrary thicknesses. Over a range of lead-tellurium oxide compositions these films are transparent and are glassy, rather than crystalline or amorphous solids.

From the analyses of the films by X-ray emission spectrography and known cathode compositions, it …


Concepts Of Form And Content In Painting, Reuben Aldridge Hale Jr. Jan 1961

Concepts Of Form And Content In Painting, Reuben Aldridge Hale Jr.

Theses

This thesis is presented in conjunction with an exhibition of non-objective paintings. The exhibition, held in the Allen Gallery from July 15 to August 4, 1961, was a selection of paintings from those produced during graduate study at Southern Illinois University. It is the purpose of this thesis to illuminate, in some respects, the paintings of the artist.
To gain insight into the totality of the work of any particular artist, it is helpful to look into the influences and concepts behind the paintings. In the case of autonomous painting, the conscious ideas of an artist cannot completely explain the …


Power Requirements For Agitation In Fully Baffled Vertical Cylinders, Leo Francis Ryan Jun 1960

Power Requirements For Agitation In Fully Baffled Vertical Cylinders, Leo Francis Ryan

Theses

The decrease in power number with increasing Reynolds number sought in this thesis was observed. However, the majority of the data is not an indication of this phenomenon. Only with a relatively high ratio of turbine diameter to vessel diameter could a power number fall-off be obtained. The power number fall-off thus appears to be dependent upon this ratio of turbine diameter to vessel diameter. When the power number fall-off was evidenced, a deep vortex existed despite the presence of full baffling, and large quantities of air were entrained by the liquid.

Even after applying pseudo corrections for both entrained …


Behavior Change Through Training, Robert Walter Messerschmidt May 1960

Behavior Change Through Training, Robert Walter Messerschmidt

Theses

This thesis represents an investigation of attitude and behavior change as a result of human relations training, The elements of heredity and environment are proffered as a basis for attitude and behavior formation. It is denoted that these elements are also instrumental in subsequent development of adult behavior.

As noted in the literature, the term "individual differences" embodies the effect of virtually unique heredity and environmental conditions to which each person is exposed. These differences are also partly determined by the growth in developmental trends, which varies from individual to individual and from time to time.

The existence of individual …

This investigation was directed toward the extension of data on the kinetics of monovalent - trivalent cation exchange and to establish data on the relationship between temperature and total capacity of an ion exchange resin. In order to compare the present study to a previous investigation by Klosowski (2), the capacity of the resin used for ferric and chromic ions was also measured.

In the kinetic study, the ferric ion-hydrogen ion exchange using Dowex 50 X-8 resin was studied in an agitated vessel. A two-bladed marine type propellor was used and the agitator speed was varied from 400 to 800 …


A Study Of A Production Control System In A Job Order Die Casting Plant, Robert Gordon Woodnorth May 1958

A Study Of A Production Control System In A Job Order Die Casting Plant, Robert Gordon Woodnorth

Theses

This thesis examines the production planning and control system in a job-order die casting plant. After comparing to the criteria for an ideal system the following changes were recommended.

1. Central work storage and dispatching. This would reduce work in process and workload fluctuations through closer planning. It would also provide a perpetual inventory system and a central control point which would be constantly informed of production progress.

2. Operator trucking. By having operators do their own trucking material handling costs and production delays would be reduced.

3. Simplified job cost accounting. The use of standard costs for finishing and …


Rigid, Unplasticized, Polyvinyl Chloride Piping : An Engineering Material Study, James Patrick Kelleher Jun 1957

Rigid, Unplasticized, Polyvinyl Chloride Piping : An Engineering Material Study, James Patrick Kelleher

Theses

Rigid, unplasticized, polyvinyl chloride is one of several thermoplastic materials which can be made available on a reasonable, commercial basis in the form of pipe, as well as in other forms necessary for the assembly of a complete piping system.

These materials offer resistance to widely varying conditions of environment, light weight, relatively low cost, ease and economy of installation, self-insulating characteristics, minimum solid-deposit tendency, and low frictional losses. On the other hand, these materials have lower mechanical properties than most metals, and these properties are subject to wider variations as a function of temperature.

Of the thermoplastic piping materials …


Zone Refining Of Anthracene, Charles Poultney Perot Jun 1957

Zone Refining Of Anthracene, Charles Poultney Perot

Theses

The process of zone refining involves the passage of a molten zone along a rod of solid. As the zone progresses, composition of the material freezing out generally differs from that melting, so solutes are redistributed. Enrichment of the major component occurs toward one end of the rod. (Usually the end of frozen.)

In the present work, impure anthracene was subjected to zone refining. Feed first run was C.P. anthracene with a known impurity of 2.0% phenanthrene. After two passes no phenanthren was detectable in the first layer frozen. (Analysis was by ultra-violet spectrophotometry.) Although the zones melted out were …

Electrodeposition Of Cellulose And Carboxy-Methylcellulose, Charles Edward Driesens Jr. Jun 1956

Electrodeposition Of Cellulose And Carboxy-Methylcellulose, Charles Edward Driesens Jr.

Theses

The previous work done by Frank Cozzarelli on the eleotrodeposition of cellulose from a sodium zincate-urea-cellulose system has been verified, except that zinc was found to deposit on the cathode at all voltages and current densities within the range of the optimum conditions for deposition. The optimum conditions are: voltage - 1.10 to 1.28 volts; current density 0.13 to 1.10 amperes/square foot; electrode material - copper. Current efficiencies range from 0.80 to 5.53%.

A chelate-like complex formed from the sodium zincate and urea which couples with the cellulose has been proposed as a possible explaination of the mechanism governing the …

The Preparation Of 2-Aminophenol-4-Sulfonic Acid From Sulfanilic Acid, Edward Jacob Mach Jun 1954

The Preparation Of 2-Aminophenol-4-Sulfonic Acid From Sulfanilic Acid, Edward Jacob Mach

Theses

Sulfanilic acid (I) was examined for purity and character. Sodium and potassium salts were acetylated and their isolation and yields were investigated.

The salts were nitrated with mixed acids and the reaction mixtures were treated in various ways to ascertain a good method for isolating the desired 2-nitro-sulfanilic acid (II). An attempt was made to characterize the reaction products, and to devise quantitative methods to estimate the yield of 2-nitrosulfanilic acid. A previously unreported by-product of the nitration, 2,4,6-tri-nitroaniline (He), was isolated. Several new salts of 2-nitrosulfanilic acid were prepared, and a possible new derivative was observed from the reaction …
