The Design And Implementation Of A Time-Shared Computer Based Construction Cost Estimating System For An Electric Utility, Thomas Arnold Westphal

Theses

The work of the distribution department of an elec tric utility involves a great deal of medium to heavy construction. This work is vital to serve the energy needs of the public. An electric utility constantly builds, reinforces, and repairs electric distribution facilities. The material and labor used to accomplish this construction is expensive. Money in sufficient amounts is seldom, if ever, available to finance all proposed construction projects. Therefore, the cost of proposed projects must be estimated in advance, so that management may decide on an economic basis which projects will be authorized.

The need for accurate construction cost …

Absorption Of Methoxyflurane By Conductive Rubber And Polyethylene Anesthetic Hose, Edward A. Kippel

Theses

This thesis presents the results of an investigation into the absorption of methoxyflurane by conductive rubber and polyethylene anesthetic hose. Previous studies are reviewed and theoretical considerations governing the diffusion process are discussed.

Diffusion coefficients are calculated for commercially available hose materials using different anesthetic concentrations and oxygen flow rates.

Data obtained is compared with the results of previous investigations (primarily concerned with sorption into rubber hose) and similar results are presented for polyethylene hose.

Graphical data is used to demonstrate the effect of hose material on inspired anesthetic concentration.

The advantage of disposable conductive polyethylene hose over reusable rubber …

Densities Of Polar And Non-Polar Compounds And Their Mixtures, Peter Norman Notwick

Theses

Two principal studies were conducted as part of this thesis: evaluation of existing correlations for predicting densities of polar and non-polar liquids and their mixtures and experimentally measuring the densities of certain liquid systems.

Utilizing a modification of the simple picnometer experimental method, data were obtained for both pure compounds and liquid mixtures. Comparison of the pure compound data with available literature sources established the reliability of the technique.

The results of the correlation comparison indicate that the Riedel equation, is the most generally reliable for predicting the densities of pure "normal" compounds. Lydersen, et al., prepared tables for the …

Steady State And Dynamic Performance Of Anisotropic Reluctance Motor, S. Chandrasekhara Rao

Theses

The paper deals with a special type of reluctance motor called Anisotropic rotor reluctance motor. As the name implies, advantage is taken of the internal anisotropy of the rotor magnetic structure. Axially laminated grain oriented silicon steel is used in the rotor. This unconventional configuration of assembly of rotor laminations results in a high ratio of direct axis to quadrature axis reluctance. Compared to the conventional reluctance motor, pull out torque of more than three times and a power factor as high as in an induction motor is obtained. Several motors of ratings up to 60 HP. were built and …

Solvent Recovery From A Complex Process Solvent Stream, John Budavari

Theses

This work deals with the recovery of solvents from a complex process waste stream containing methylene chloride chloroform, n-propyl alcohol, isopropyl alcohol, heptane and butyl acetate. In addition to the above-mentioned solvents, the mixture is saturated with water (ca. 1%), hydrochloric acid, and contains organic and inorganic process impurities. The objective was to develop the simplest economical recovery process utilizing vapor-liquid equilibrium data, distillation and extraction procedures. Considerable effort was expended to develop precise and reliable assay methods. A process which met the necessary requirements of maximum solvent recovery with minimum waste disposal, was developed.

An Evaluation Of The Applicability Of A.N.S.I. Standard Ph-2.9 To Contemporary Medical X-Ray Films Designated For Automated Processing, David Binko

Theses

Three medium speed screen-type medical x-ray films were exposed and manually processed in accordance with the procedures outlined in A.N.S.I. Standard PH-2.9, "Sensitometry of Medical X-Ray Films". Subsequent to processing, all samples were evaluated upon the response variables of base plus fog density, maximum density, A.N.S.I. speed, and A.N.S.I. contrast. A second set of film samples, exposed identically to the manually processed samples, were processed in a ninety-second cycle automated system. After sensitometric evaluation of the automated samples, a statistical comparison of the results obtained by both processing procedures was executed. In the second phase of the investigation, a factorial …

Effect Of Organic And Inorganic Silver Complexing Agents On Image Quality, Stephen Scharfstein

Theses

Image Quality of plus-x film processed in a monobath solution containing an inorganic silver complexing agent ( sodium thiosulfate ), was compared to plus-x film processed in an organic silver complexing agent ( mercaptoacetic acid ). A control run using DK-50 was also made. The image quality of the film was best with DK-50 and worst with mercaptoacetic acid. Image quality was determined by the results of the following tests: 1 ) Resolving Power 2 ) Acutance 3 ) MFT 4 ) Granularity

Image Spread In The Infectious Development Of Graphic Arts Film, William Colgan

Theses

The problem of this experiment is to determine which of three factors; sulfite level, bromine level, and development time, affect the image spreading during the infectious development of a graphic arts film. Three different levels of each factor will be studied. The method used consists of measuring the distance between two fine edges on a test target. This test target is then contact printed onto the graphic arts film. The distance between the two fine edges on the graphic arts film is then measured. Any difference between the two distances will be the result of image spreading. It is these …

The Usability Of Tungsten Halogen Lamps As Secondary Standards Of Luminous Intensity, James Buchek

Theses

Tungsten halogen lamps are widely used as sources of radiant intensity because of their compactness and long life. Little is known, however, about their usefulness as secondary standards of radiant intensity. What is unknown is the polar distribution of the emitted light. If it is irregular in space, it may be possible to use a frosting as a means of providing for a more uniform distribution. In addition, use of a black sleeve over the lamp may be used to control emitted light, and also control the temperature of the lamp. To perform the experiment, a lampholder was designed and …

A Comparison Of Phenidone Determinations In Photographic P.Q. Developers, Ernest Dankert Jr

Theses

Five methods for determining Phenidone in Phenidone-hydroquinone were investigated with aspect to accuracy, precision, and time required to perform the analysis. The methods include ultraviolet spectroscopy, colorimetric estimation, and cerimetric titrations. A cerimetric analysis was found to have the greatest precision, a 7% error at the 95% confidence level. All analyses required approximately the same time to complete. Each analysis allowed the accuracy to be adjusted, i0 compensate for operator techniques

Rate Of Reduction Of Silver Ions And Silver Complexes In Solution With Developers, Richard Shadrach

Theses

The change in rate of reduction of silver from solutions of varying silver ion and silver sulfite complex by hydroquinone and metol was studied. The silver ion concentration was varied and the silver complex concentration was held constant. The rate was found proportional to the square root of the silver ion concentration for development by hydroquinone. The silver complex concentration was varied and the silver ion concentration was held constant. The rate of reduction increased as the complex concentration increased for both hydroquinone and metol developing agents, showing that the complex was being reduced. The rate appeared to be proportional …

A Study Of Latent Image Fading In So-343, Mitchell Glasser

Theses

Experimental evidence indicates that a high intensity, short duration exposure produces surface image exclusively in this emulsion. The ensuing fading was shown not to be caused by internal migration of the latent image. The high intensity exposure produced a massive amount of sub image nuclei which could subsequently be rendered developable by a low intensity post exposure. This latensification failed to achieve an improvement in image stability, in that the amount of fading was shown to be solely a function of the density of the fresh exposure. It was hypothesized that although this treatment did raise some grains from an …
