Liquid Transmission Line Pulser Circuit For Laser Excitation, Carl Stultz

Dissertations and Theses

The subject of this thesis is the study of liquid dielectric transmission lines and their potential application as an excitation source in high speed, high-repetition rate laser designs. The design problems associated with the construction of high repetition rate (khz), short wavelength lasers have been reviewed and the major shortcomings of conventional electrical driving circuits identified. The identification of these shortcomings and a review of the available literature on electrical circuits for various types of lasers suggested that liquid dielectrics and transmission lines could potentially have significant advantages over more conventional circuitry used in high repetition rate, short wavelength lasers. …

Radio-Frequency-Excited Carbon Dioxide Metal Waveguide Laser, Jonathan Gary Grossman, Lee W. Casperson, O. M. Stafsudd

Electrical and Computer Engineering Faculty Publications and Presentations

A new type of waveguide laser is described in which a single-surface concave metal waveguide also doubles as the grounded electrode in a radio-frequency-excited gaseous discharge. The laser’s output modes and spectrum have been studied theoretically and experimentally for cw CO₂ operation of the laser. Overall operating efficiency and mode stability are comparable with those of conventional dielectric waveguide CO₂ lasers, and advantages of the metal waveguide laser include convection cooling, intracavity mode control, and partial self-alignment.

Research And Development Effects On Economic Growth: Implications For The Portland Smsa, James G. Strathman

Center for Urban Studies Publications and Reports

Promoting a high- technology economic base has been widely adopted as a regional development "policy for the 80's." To this point, however, it appears that little consideration has been paid to questions regarding the feasibility of this policy as it relates to structural and locational characteristics of the regional economy. This paper will discuss those attributes of the regional economy that typically contribute to the expansion of high- technology activities, with particular attention paid to expansion potential in the Portland SMSA. High-technology activities are defined according to product cycle theory, and the attributes of the regional economy are examined with …

Analytical And Experimental Stresses In Concrete Pavements And Unbonded Overlays, Ahmad Jaber

Dissertations and Theses

The principal objective of this study is to determine the accuracy of calculating stresses in concrete pavements and unbonded overlays under different loading conditions. The computed stresses for the single layer pavements are obtained based on Westergaard theory, the finite-element model (ILLI-SLAB), and the elastic layered model (ELSYM5). For the two-layer unbonded systems, stresses are estimated based on the finite-element theory and the Portland Cement Association design method. The experimental results for the comparison were available from a series of tests done on model scale concrete pavements and unbonded overlays. The results of present investigation show that the computed stresses …

A Study Of Single Angle Compression Members, James Robert Callaway

Dissertations and Theses

A study was undertaken to investigate the compressive capacity of a specific group of single angle members.

A review of existing literature and techniques was presented. Laboratory compression tests were performed on 22 angle members of four different sizes and two different lengths. Additional tests were performed to determine the yield strength of the material. The results, normalized with respect to the yield stress, were tabulated and discussed.

Two existing analytic models were used to attempt to predict the ultimate capacity of the test members. The first, an elastic method, was based upon the AISC combined stress equation. The second, …

External Dependence And National Urban Development Policy: A Structural Analysis Of Graduate Unemployment In Nairobi, Kenya, Fantu Cheru

Dissertations and Theses

This dissertation examines the attempts by the government of Kenya to develop and implement policies directed toward the problem of urban unemployment. Specifically, this study focuses upon two policy areas directly related to the problem of urban unemployment: education and economic growth. Central to the urban unemployment problem is a potential conflict arising out of a rapidly growing number of school graduates on the one hand, and on the other, the limited opportunities for a sufficient level of employment for this segment of the labor force. An additional element of this study is an examination of the possible consequences of …

Institutional Environments As Perceived By The Faculty And Administrators At Six Small Liberal Arts Christian Colleges, Jeffrey Thomas Fouts

Dissertations and Theses

The purpose of this study was to determine if the small liberal arts Christian colleges provide a distinctive environment apart from the traditional classifications of colleges and universities. The environments of the six sample colleges were assessed by administering the Institutional Functioning Inventory (IFI) to faculty and administrators. Statistically significant differences were found among the colleges on eight of the 11 environmental dimensions. However, it was concluded that the colleges constituted a relatively homogeneous group on all dimensions measured except Self-Study and Planning. Total sample means on the 11 scales of the IFI allowed for a generic description of 11 …

(2) A list of key variables was developed for inclusion in the support system. Data were gathered and stored for a preliminary version of the DSS. (3) …

A Descriptive Predictive Model For The Employment Of Computer-Based Management Information Systems For The Government Of A Developing Country: Case, Iran, Hossein Bidgoli

Dissertations and Theses

This study was undertaken to identify the most decisive variables in the successful employment of a Computer-Based Management Information System (CBMIS) in a developing country such as Iran. A descriptive model was designed. Using a series of predictive models, several dimensions of successful CBMIS employment were investigated. Data were collected via a questionnaire sent to 79 Iranian governmental computer installations. Questions posed by the study are: (1) Under what conditions should a developing country continue to operate manually? (2) If computerization is feasible, what should the acquisition criteria be? (3) What are the most important variables for optimum utilization of …

An Exploratory Functional-Structural Analysis Of American Urban Traditional And Alternative Secondary Public Schools, Mary Ellen Sweeney

Dissertations and Theses

This study investigates the way traditional and alternative secondary public school organizations are structured to impact youths. Some studies have found that traditional secondary schools utilize inappropriate and outdated organizational elements and arrangements. Alternative schools with different organizational arrangements have been initiated in public school districts to institute school reform measures. The three goals of this study are to: (1) collate a large share of the literature on the function, social context and organizational characteristics of conventional and alternative secondary public school organizations, (2) explicate a theoretical framework or interrelated set of propositions of organizational principles regarding modern organizations, including …

Secondary Stresses In Bowstring Timber Trusses, John F. Bradford

Dissertations and Theses

This study was undertaken in order to determine analytically the magnitude of the secondary (i.e., joint deflection induced) moments in the continuous glued-laminated chords of bowstring timber trusses. Traditionally, these moments have been assumed to be small and therefore neglected. The American Institute of Timber Construction makes no mention of these moments in their recommended design procedure.
