On The Analysis Of The Timoshenko Beam Theory With And Without Internal Damping, Chinubhai Doshi

Theses

The Timoshenko beam equation in terms of variable 'wB' is derived where 'wB’ is the deflection due to the bending of a beam. The equation is used to analyze an infinite beam loaded with (i) a concentrated transverse load and (ii) an impulse. It is also shown that the rotatory damping in the equation eliminates the increasing amplitude in the propagation of the bending moment when an impulse is applied to an infinite beam. Also the general procedure for the anlysis of a non-homogeneous equation is explained.

Art Therapy For Emotionally Disturbed Children: Clay And Media Dimension Variables, Wendy Wirth

Theses

This thesis investigates the application of art therapy for the evaluation and treatment of emotionally disturbed children, with a specific focus on the use of clay and Media Dimension Variables (MDV). The author posits that clay is an exemplary medium for therapeutic intervention due to its plasticity, three-dimensional nature, and capacity to range from resistive to fluid states. The study adopts Kagan’s (1969) MDV system to structure therapeutic interventions, categorizing art activities by three distinct variables:

• Structure: The extent of guidelines or controls (High vs. Low). 

• Media Quality: The inherent properties of the material (Resistive vs. Fluid). 

• Task Complexity …

A Study Of The Mechanism Of The Sabattier Effect, Steven Oshry

Theses

Conditions for producing the Sabattier effect in Eastman fine grain release positive 5302 film were established. Modifications of the second developer to develop more internal latent image by the addition of potassium iodide or to increase solution ~ physical development by the addition of sodium thiocyanate and sodium sulfite were performed. These modifications made no significant change in the Sabattier effect. When chemical fog (from sodium borohydride) was substituted for the exposure during development, no reversal corresponding to the Sabattier effect was obtained.

Readability Determination Using Superimposed Random Noise Patterns, Michael Dennison

Theses

A readability gauge was constructed which objectively gauges the readability of printed matter. In the past such gauges have been produced using photographically created noise. In this study a gauge was constructed using noise generated by a computer. This gauge was evaluated and compared with a gauge produced using the photographic technique of noise generation. The computer generated gauge proved to be as good as the photographic gauge at detecting differences in legibility of printed type. It was also found that the only two causes of variability in the legibility samples used were letter size and letter contrast. Using only …

Modifications Of A Herrnfeld Sensitometer For Interimage Studies, Charles Tobin

Theses

An available Herrnfeld Sensitometer has been rebuilt and modified to include a six position filter wheel, three narrow band interference filters, a separate D.C. power supply, and a central control panel. The modified sensitometer expedites the single layer exposure of color film. The system accomplishes this by using interference filters whose band-width peaks are matched to the peak spectral sensitivity of each emulsion layer to be exposed. A D.C. power supply has been included to eliminate lamp ripple caused by the oscillations that occur in the A.C. line. In depth experimentation (approximately 20 rolls of film) produced exposures closely approximating …

Evaluation Of Turbine Blade Root Damping, Curtis Beck

Theses

A test program has been conducted to measure the vibration damping of three designs of steam turbine blades. These blades were tested in their root attachments, sectioned from retired rotors. Blade loading was accomplished in a new type of blade damping test rig and damping was evaluated in the lowest tangential and axial blade modes. The test environment was room temperature air. The damping rig concept and development is presented in detail as well as results of an intensive test program. The blade designs are designated as Types A, B, and C, where Types A and B were of a …

Concur: A High-Level Language For Concurrent Programming, Karen Anderson

Theses

A language CONCUR is defined which permits the definition and initiation of asynchronous processes. The language was inspired by Modula, a language proposed by Wirth for realtime programming. CONCUR removes Modula's restrictions on the placement of process declarations and invocations in order to study the implications of process support more fully- Most of the other sophisticated features of Modula, such as modules, structure types, and procedures, have also been removed to focus attention on processes and their particular requirements. A general methodology is suggested for concurrent programming, and several sample programs are presented which demonstrate concurrent programming with CONCUR. Finally, …

An Exploratory Examination Of Age, Attitudes Toward Death, Experience With Death, And The Christian Religion, Barbara L. Sanders

Theses

This exploratory study by Barbara L. Sanders investigates the complex relationships between age, personal experiences with death, attitudes toward mortality, and Christian religious beliefs. Motivated by personal and professional encounters with individuals across the lifespan, the author seeks to understand how these variables interrelate and challenge commonly held assumptions—such as the belief that Christians are more accepting of death or that children fear death more due to inexperience.

The research was conducted through a questionnaire distributed among 60 participants across three distinct age groups: adolescents (10–15), adults in their early middle years (36–49), and older adults (65+). The questionnaire assessed …

Second Stage Autoradiographic Amplification Of Developed Underexposed Tri X Emulsion Images, David Dempster

Theses

A series of del iberately underexposed Kodak Film Type Tri-X negatives were first, conventionally developed, the image silver made radioactive with sulfur-35 thiourea, and by using an autoradiographic technique, the image recovered on X-ray film. The resolution and characteristic curve parameters of the final image compared to those of the original donor image were determined by varying the secondary exposure time (contact time between radioactivated film and x-ray emulsion), type of x-ray films and exposure levels. The Tri-X Pan emulsion donor image was amplified using Kodak "NMC", "MA" and "RP" X-ray films as receivers. "NMC" was slightly preferable to "MA", …

An Experimental Comparison Of Emulsions Of The Same Type Of Different Iodide Levels, Seilay Wong

Theses

Single run neutral type iodobromide emulsions of 1, 5 and 10 mole % were made similarly. On development to 0.7 gamma with Kodak developers D23 and DK50, it was found that the 10% iodide emulsion had faster speed than the 1% iodide emulsion but yet its granularity was no greater than the 1% iodide emulsion. There is no evidence that the performance in D23 as compared to DK50 was improved with increasing iodide percentage.

Effect Of Concentration And Ph On Parametric Pumping Separations, Tsu-Kun S. Hsieh

Theses

The technique of parametric pumping represents a new and valuable development in the separation science of proteins. Many conventional protein separation are often processed batchwise. However, parametric pumping offers the possibility of continuous processing; the continuous process provides both the advantages of decreasing the processing time and of minimizing degradation.

Preliminary step testing experiments were conducted to study the equilibrium of protein between the stationary and mobile phase of the sephadex ion exchanger.

It was the purpose of this research to study the feasibility of operating a semi-continuous parametric pump with a sephadex ion exchanger for the separation of a …

Optical Line Width Measurement Using Spatial Filtering, Suzanne Weaver

Theses

The measurement of line widths optically allows fast, easy non-contact measurements and finds application in both research and development areas, as well as the production environments There exists presently a. need to increase the measurement accuracy of the width of small lines in the under 10 to 20 micrometer region. As accuracy may be achieved by calibration, there is interest in reducing the measurement variability. One technique of reducing variability, that of using a coherent microscope system that allows spatial filtering of the image of the line being measured, was breadboarded using high contrast etched chromium on glass lines, and …

Elements Of Visual Perception, Dudley Killam

Theses

The roles of scale, contrast and spectral difference in visual detection and recognition was investigated. Geometrical target arrays were produced and projected using a rear projection apparatus. Scale was varied using combined photographic reduction and slide projection. Contrast levels were adjusted in projection of lithographic target arrays using neutral density filtration arrangements in the projection apparatus. Experimentally obtained cumulative probability of detection and combined detection and recognition was examined relative to established combinations of target scale, contrast and spectral difference. A method for the characterization of target pair differences was offered and analyzed. The relation of scale, contrast and perceptual …
