The Application Of Limit Analysis To Shell Structures Using Existing Finite Element Analysis Codes, George G. Myers Jan 1977

The Application Of Limit Analysis To Shell Structures Using Existing Finite Element Analysis Codes, George G. Myers

Retrospective Theses and Dissertations

A ramjet inlet duct structure has been designed using nonlinear structural analysis to allow local plastic deformations which result in structural weight reduction. To establish the feasibility of reduced shell thickness, the Lower-Bound Theorem of limit analysis has been applied using an existing finite element analysis computer code intended for elastic analysis. The results of the analysis were verified by structural testing. Predicted stresses and deflections showed good correlation with measured values up to the point of failure. This work was supported by the U.S. Air Force Aero Propulsion Laboratory, Wright-Patterson Air Force Base, Ohio, under Contract No. F33615-72-C-1366.

Distraction And Dissonance: A Model Of The Persuasive Process, Davis Albert Foulger Jan 1977

Distraction And Dissonance: A Model Of The Persuasive Process, Davis Albert Foulger

Retrospective Theses and Dissertations

After exploring the successes, failures, and conflicting explanations for results in two communications research traditions, distraction and counter-attitudinal advocacy, an attempt was made to explain these results in terms of a more comprehensive theory. Distractions were organized into classes defined by their strength and relevance to the message, demonstrating how these and other factors affected the persuasiveness of a message. On the basis of this theory an untested class of distractions, cognitive distractions, were hypothesized. This class of distraction, related to cognitive dissonance, was then used to integrate the conflicting research in counter-attitudinal advocacy. On the basis of this theory, …

Eye Color And Its Possible Relation To Behavior, Debra Lee Hollister Jan 1977

Eye Color And Its Possible Relation To Behavior, Debra Lee Hollister

Retrospective Theses and Dissertations

A variable that is capable of indicating one's cognitive and motor capacities has been the dream of many researchers. Until recently however, no researcher has seriously considered an independent variable that is obvious among all people regardless of race or culture. This variable is eye color. This paper is a review of the experimental literature in this field and covers many areas including sociability, perception, learning, athletic abilities, and a few medical anomalies. Several alternative hypotheses are also offered as reasons for the obtained correlations. These ideas include culture, learning, and environment. Two other hypotheses are also presented to explain …

An Organizational Communication Analysis Of A Medium-Sized Newspaper, Sara Baldwin Howze Jan 1977

An Organizational Communication Analysis Of A Medium-Sized Newspaper, Sara Baldwin Howze

Retrospective Theses and Dissertations

A medium-size newspaper in Central Florida was observed for 8 weeks in the Spring and Summer of 1976 and 58 employees interviewed to determine internal communication patterns and measure attitudes toward the communication system, organization and job related variables. A system theory of organizations provided basic theoretical assumptions. Since communication activities occur within the framework of internal organization elements such as structure, objectives, leadership style, reward system, technology, intergroup relations, and individual employee characteristics, those elements were described. Communication activities were reported in terms of message purpose, network traversed, method of diffusion and relationships. Findings indicated that the nature and …

Alcoholism In Women, Sandi Abilock Levine Jan 1977

Alcoholism In Women, Sandi Abilock Levine

Retrospective Theses and Dissertations

Alcoholism is a serious public health problem. There is strong evidence that the rate of alcoholism, especially among women is increasing. Until recently, there has been very little research on alcoholic women. The recent increase in the number of known female alcoholics may be related to the new liberation and freedoms women have gained. While the research literature does not support the notion of a typical female alcoholic personality type, certain recurrent characteristics have been noted. This paper attempts to document the problems which appear to be related to women who become alcoholics and to look at the variety of …

Antibodies To Milk Antigens In Human Coronary Heart Disease, Efstathios Spinos Jan 1977

Antibodies To Milk Antigens In Human Coronary Heart Disease, Efstathios Spinos

Retrospective Theses and Dissertations

Milk protein has been implicated as a factor in the development of atherosclerosis. Significantly higher titers of antibodies (P < 0.0002) toward milk antigens were observed in patients suffering from coronary heart disease as compared to age matched controls. These hemagglutination titers were not sex related but may have been related to age. Specificity of the antigen-antibody reaction was demonstrated by a hemagglutination inhibition test. The complement fixation test was evaluated and was less sensitive than the tanned hemaggIutination test. Treatment with 2-mercapto-ethanol resulted in reduced hemagglutination titers, indicating that significant antibody activity may be due to IgM. A special application of the Combs test detected specific antibodies on the surface of tanned and coated RBC which did not otherwise produce detectable agglutination.

Hardware And Software Considerations For Improving The Throughput Of Scientific Computation Computers, Glenn Allen Sullivan Jan 1977

Hardware And Software Considerations For Improving The Throughput Of Scientific Computation Computers, Glenn Allen Sullivan

Retrospective Theses and Dissertations

In this paper, hardware and software techniques are presented for improving the Throughput (defined as computations per dollar) of computing systems which are oriented towards high-precision floating point computations. The various improvements are referenced to a baseline of the PDP 11/20, the NOVA 1200, and the TI 960A, all 16 bit minicomputers. The most beneficial hardware improvement is the inclusion of a Floating Point Processor, which yields up to 200X Throughput increase over a software floating point package. The inclusion of a cache high speed local memory and the availability of Polish Notation format instructions are shown to provide less …
