The Uniform Hanging Cable As A Translational Vibration Absorber., Charles W. Springfield Jr Jan 1977

The Uniform Hanging Cable As A Translational Vibration Absorber., Charles W. Springfield Jr

All ETDs from UAB

The small, lateral vibrations of a system consisting of a uniform cable suspended from a mass in a gravitational field and having a lower end mass are considered in this thesis. The frequencies and modal configurations for free vibration were determined. Secondly, a harmonically varying forcing function was applied to the upper mass for the purpose of studying the forced motion of the system. Finally, it was shown that by proper selection of the cable length, the cable-lower mass system can serve as a dynamic vibration absorber for the forced upper mass.

The past fifteen years in this country have seen the perinatal period of human existence become the subject of increasing research. Perinatal mortality rates in the United States remain high by comparison with those observed in other developed countries of the world. This difference may be partially explained by the poor distribution of medical care and by less than optimum clinical implementation of available knowledge about pregnancy and parturition. However, in many instances the etiology and mechanisms of death before, during and immediately after birth are not well understood.

Solution Properties Of Some Iron And Copper Macrocycles., Danny Gene Miles Jr Jan 1977

Solution Properties Of Some Iron And Copper Macrocycles., Danny Gene Miles Jr

All ETDs from UAB

Solution studies were conducted on iron(ll) phthalocyanine (FePc) and three copper macrocycle complexes. Concentrations of saturated solutions of FePc in pyridine, 2-methylpyridine, 3-methy1 - pyridine, and 4-methyl pyridine were determined from visible spectral data, and in dimethyl sulfoxide (DMSO) were obtained from atomic absorption analysis. Kinetic data for the dissociation of FePc in pyridine is reported. Magnetic susceptibilities of FePc in pyridine, 2-methylpyridine, 3-methylpyridine, and 4-methylpyridine indicate the formation of a d5 low-spin radical. In DMSO, FePc is diamagnetic. However, a paramagnetism plausibly explained by a d5 high-spin radical occurs with heating in the presence of methylene chloride.The macrocycle compounds …

Determining Whether Position Specification Of The Relevant Component Within A Cue Is Necessary For Cue Effectiveness., Camilia Gailani Cline Jan 1977

Determining Whether Position Specification Of The Relevant Component Within A Cue Is Necessary For Cue Effectiveness., Camilia Gailani Cline

All ETDs from UAB

The study of audition has in recent years shifted from the investigation of noise bursts, clicks, and simple tones to that of more complex multicomponent tones and their interrelationships. Early research in auditory processes assumed the simplest form, wherein such parameters as frequency, amplitude, and duration of a simple stimulus were investigated. Although sound sources in the environment rarely generate simple waveforms, the research was relevant in establishing the foundation on which current auditory research of complex tones is based. The auditory system functions in a natural environment where a variety of noises, speech sounds, and music comprises the source …

Effect Of Hand Dominance On Rate Of Learning And Bilateral Transfer., Memory Hammond Gleason Jan 1977

Effect Of Hand Dominance On Rate Of Learning And Bilateral Transfer., Memory Hammond Gleason

All ETDs from UAB

People generally have a dominant and a nondominant hand. Dominance refers to the ability to perform a task better with a particular hand [Hand preference does not necessarily mean hand dominance] (Rigal, 1974). For example, a child may show tendencies to be left hand dominant; however, his parents may insist that he use his right hand. As he grows older, he will use his right hand as his preferred hand, but in fact his left hand will be dominant. It would be advantageous to determine true dominance in order to provide more optimal learning conditions.It has been well established (Cook, …

The Optimum Design Of A Step Voltage Regulator., Kenneth M. Mcwilliams Jan 1977

The Optimum Design Of A Step Voltage Regulator., Kenneth M. Mcwilliams

All ETDs from UAB

Optimum designs of voltage regulating transformers can be achieved only when the designer knows the characteristics of the different design parameters and how they affect the total design. The criteria controlling the design of most voltage regulating transformers are not readily available since this information is usually found in company files or the files of individual design engineers. The criteria used are often based on the experience of these engineers and in many cases have never been verified. This thesis presents some of the common design parameters for voltage regulating transformers and computer generated data showing how the total design …

Ultrasonic Attenuation In As-Deposited Inconel 182 Weld Metal And Recommended Techniques For Discontinuity Evaluation., Richard Lamar Lawrence Jan 1976

Ultrasonic Attenuation In As-Deposited Inconel 182 Weld Metal And Recommended Techniques For Discontinuity Evaluation., Richard Lamar Lawrence

All ETDs from UAB

This thesis reports on a study of the problems associated with the ultrasonic evaluation of full penetration welds in pressure retaining bi-metallic and tri-metallic joints involving as-deposited austenitic weld material. The weld joint design was one simulating a component on a nuclear reactor known as a safe-end-to-nozzle. Because the joint is part of a nuclear reactor, explicit design requirements are set forth by the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Section III. Furthermore, ultrasonic examination guidelines are prescribed in ASME Sections III and XI.

Curvature Contingent Color Aftereffects., John Fred Whirley Jan 1976

Curvature Contingent Color Aftereffects., John Fred Whirley

All ETDs from UAB

This paper will deal with curvature contingent color aftereffects (AE), a development from the pattern contingent aftereffects reported by Celeste McCollough (1965). After McCollough’s findings are described briefly, the relative importance of spatial frequency characteristics in inducing AE will be discussed. Then attention will be given to AE contingent on direction of curvature of curved line patterns (Riggs, 1973). Riggs’ explanation will be contrasted with those of other authors who attempt to explain his curvature AE in terms of orientation contingency reported in the earlier studies. The lack of attention given to possible frequency interaction in curvature studies is discussed, …

Locus Of Control Differences In The Acquisition Of Electromyographic Biofeedback Training And In Self-Reported Relaxation Under True And False Feedback Conditions., David S. Siegel Jan 1976

Locus Of Control Differences In The Acquisition Of Electromyographic Biofeedback Training And In Self-Reported Relaxation Under True And False Feedback Conditions., David S. Siegel

All ETDs from UAB

The present experiment was designed to investigate a proposed relationship between the construct of locus of control (Rotter, 1966) and the ability to learn to relax via Electromyographic (EMG) biofeedback training. The main purpose was to explore the notion, reviewed by Lefcourt (1972), that certain cognitive properties are associated with locus of control. The proposal was that these cognitive properties are important to learning to relax utilizing EMG feedback. Thus, one aim was to demonstrate locus of control differences in learned relaxation via EMG feedback training. Another aim was to demonstrate locus of control differences in the utilization of false …

Gravity Induced Stresses In A Shrink-Fit Disk., Imogene L. Baswell Jan 1976

Gravity Induced Stresses In A Shrink-Fit Disk., Imogene L. Baswell

All ETDs from UAB

Elasticity methods offer many opportunities to investigate the stresses in a system. However, only a very small percentage of design or analysis problems can be treated by application of analytical elasticity techniques. This, of course, is due to mathematical difficulties associated with the solution of the governing equations subject to prescribed boundary conditions. Several techniques of an approximate nature have been developed for the treatment of more complex problems, among them being finite difference techniques and finite element approaches.

An Investigation Of The Friedel-Crafts Condensation With Homoterpenyl Methyl Ketone., Ashok Ramchandra Bapat

All ETDs from UAB

In recent years many naturally occurring substances have acquired a great deal of attention, due primarily to their biological or synthetic values. -Pinene is the well known naturally occurring substance which is the main component in longleaf or slash pine tree oleoresin. a-Pinene and some of its derivatives have been used as starting materials in industrially applied synthetic organic schemes. Such applications span the gamut from the polymer field to the flavor industry. One such derivative, homoterpenyl methyl ketone, is a readily available keto-y-lactone.
