A Study On The Stabilization Of A Floating Platform, Waldo Lizcano

Dissertations and Theses

A new technique for controlling the pitching motion of a floating platform is proposed in this study.

The floating platform is assumed to be a simplified model of the columnar type rectangular platform supported by buoyant force from four cylindrical legs. The control arrangement consists of water jet streams immerging horizontally from two points located some distance apart on each leg to form a restoring couple. The water jet streams can be shifted t0 opposite horizontal positions or to the vertical downward ,positions according to control requirements. They are governed by angle control criterion as well as velocity control criterion. …

Male Client Expectations Of Female Therapists, Phyllis Whitman Heims, Susan Annette Ofstad

Dissertations and Theses

This practicum intends to explore the existence and nature of male client expectations of female therapists. The underlying assumptions of this study include: (1) clients have expectations; (2) sex roles exist in society; and (3) the sex of either the therapist or the client is a variable in the therapeutic situation.

To carry out this study it is necessary to pursue the following tasks. The first step will be to define possible client expectations of therapists. Using this information, a questionnaire will be developed to verify the existence of these expectations. In addition, the questionnaire will hopefully indicate whether these …

The Analysis Of The Deflection And Containment Of A Hot Plume By Side Draft Exhaust Hooding, Douglas H. Macgowan

Dissertations and Theses

A common industrial ventilation and pollution problem results when a thermally buoyant polluted plume of air must be exhausted away from a work area to allow achievement of air pollution standards. Generally, a close fitting canopy hood is one of the most effective means of exhaust containment; however, physical restrictions or the operation itself often prevent such an arrangement, and a hood located to the side of the operation is required. This arrangement requires the exhaust to bend and contain the vertically rising plume with a horizontal sweep of exhaust air across the surface of the operation.

Bayesian Inquiry: An Approach To The Use Of Experts, King G. Yee

Dissertations and Theses

Subjective information is a valuable resource; however, decisionmakers often ignore it because of difficulties in eliciting it from assessors. This thesis is on Bayesian inquiry and it presents an approach to eliciting subjective information from assessors. Based on the concepts of cascaded inference and Bayesian statistics, the approach is designed to reveal to the decision-maker the way in which the assessor considers his options and the reasons he has for selecting particular alternatives. Unlike previous works on cascaded inferences, the approach here focuses on incoherency. Specifically, it employs the use of additional information to revise and check the estimates. The …

The Design Of An Automatic Electronic Preanodizer, Armen C. Grossenbacher

Dissertations and Theses

The topic of this thesis is the design of an automatic preanodizer to be used to preadjust precision tantalum resistors by anodizing their surfaces. The purpose of the preanodizer is to generate a controllable voltage ramp to be applied to a set of tantalum resistors which are immersed in a suitable electrolyte. The slope and maximum value of the voltage ramp are set to produce the current required for proper anodization of the resistors. The rate of anodization determines the rate of change of the resistor value. This thesis covers the design of an electronic device to meet a set …

The Chemistry Of Chromium (Vi) And Chromium (V) Oxide Fluorides, Patrick Jay Green

Dissertations and Theses

New preparative routes to chromyl fluoride were sought. It was found that chlorine monofluoride reacts with chromium trioxide and chromyl chloride to produce chromyl fluoride. Attempts were made to define a mechanism for the reaction of ClF and Cr0₃ in light of by-products observed and previous investigations. Carbonyl fluoride and chromium trioxide react to form chromyl fluoride and carbon dioxide. A mechanism was also proposed for this reaction. Chromium trioxide with MoF₆ or WF₆ reacts to produce chromyl fluoride and the respective oxide tetrafluoride.

A Survey Of Myths Concerning The Crime Of Rape, Marilyn Hammon, Joyce Jerabek, Michèle Mairesse

Dissertations and Theses

In view of the proliferation of recent publicity on the topic of rape via the news media and popular publications, the researchers decided that a study concerning rape would be timely and informative. An examination of the literature resulted in the discovery that there were only two principal studies published. These were by John MacDonald, Rape Offenders and Their Victims, 1971, and Menachem Amir, Patterns in Forcible Rape, 1971. Other sources invariably used the results of these studies as a basis for their comments and conclusions. The recurring emphasis on the commonly held myths (as described later in this study) …

Local Government And Manpower Programs For The Disadvantaged: An Evaluation Of The Portland Concentrated Employment Program, Lois Farrer Copperman

Dissertations and Theses

Manpower programs for the disadvantaged have been operated in the United States for approximately fifteen years. The programs - introduced under the authority of the Manpower Development and Training Act of 1961, the Economic Opportunity Act of 1964, the 1967 amendments to the Social Security Act, and the Comprehensive Training and Employment Act of 1973 - were all concerned with the employment and earning of certain groups. This body of legislation was intended to intervene in particular sectors of the labor market having a deferentially high unemployment rate, not offset by higher wages and other benefits. The intent was to …

Symbol And Artifact: Jungian Dynamics At Mcluhan's Technological Interface, Mike Amana Glick

Dissertations and Theses

Our goal was to establish some form of interpretation between the analytical work of Carl Jung in depth psychology and the views of Marshall McLuhan regarding the impact of media. It was hoped that such a correlation of contrasting viewpoints would yield additional insight in the study of mass reactions to media.

In accomplishing this purpose a “universe” based upon analytical psychology was juxtaposed with an expressly “McLuhanesque” analysis of media and technological effects. After establishing correlations between the major dynamics of the two systems, several functional conclusions were reached. These are: (1) that media have an inescapable influence, (2) …

The Pci Resurgent: 1943-1945, Karen Adele Tosi

Dissertations and Theses

The Italian Communist Party (PCI) emerged from the chaos of the Italian defeat in 1943 as a powerful and cohesive movement. Based upon organizational development throughout the years of Fascist rule in Italy, plus a combination of vigorous partisan activities and a willingness to compromise politically in exchange for governmental participation, the PCI showed promise for achieving economic and social change in Italy. Conservative countermeasures and Allied pressures, however, diminished the Communist advantage until, by 1947, the Party was no longer represented in the postwar government. The success apparent in the economic arena due to the Christian Democrat's program initiated …

Social Problems And Collaborative Planning: Toward A Theory And Model Of Social Planning, Marjorie M. Ille

Dissertations and Theses

The concern of this dissertation is planning theory and practice; its purpose is to make planning more responsive to the problems of the city. The premise that the study is built on is that social planning must be in harmony with the nature of its subject matter, and that social problems is its subject matter. The supposition is that if we grasp the nature of social problems and build planning theory and practice on these insights, planning efforts will be more relevant and more effective.

The approach is a theoretical one; social problems are the starting point. After urban problems--and …

Threshold Characteristics Of Multimode Laser Oscillators, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

The oscillation characteristics of a multimode laser are considered in detail, and for the first time saturation by all of the cavity modes is included. Analytical expressions are obtained for the mode amplitudes, linewidths, and over‐all spectral characteristics of lasers operating above and below threshold. It is found that with increasing excitation the spontaneous emission spectrum is gradually resolved into a set of narrow discrete modes. Slightly above threshold the number of modes reduces in a homogeneoulsy broadened laser until only a single mode is oscillating strongly. The theoretical results are in agreement with experimental data that have been reported …
