Behavior Of Square And L-Shaped Slender Reinforced Concrete Columns Under Combined Biaxial Bending And Axial Compression, Wen Hu Tsao

Dissertations

A numerical analysis was developed to evaluate the complete load-deflection and moment-curvature relationships for square and L-shaped slender reinforced concrete columns subjected to biaxial bending and axial load. This computer model can be used for any cross section geometry and material properties of normal concrete. The analysis was based on a deformation control and both the ascending and descending branches of curves can be studied. The finite difference method was introduced to calculate the deflections which satisfy the compatibility equations. Six square slender columns and eight L-shaped slender columns were tested to compare their experimental load-deformation results with the analytical …

A Generalized, Parametric Pr-Qmf/Wavelet Transform Design Approach For Multiresolution Signal Decomposition, Hakan Caglar

Dissertations

This dissertation aims to emphasize the interrelations and the linkages of the theories of discrete-time filter banks and wavelet transforms. It is shown that the Binomial-QMF banks are identical to the interscale coefficients or filters of the compactly supported orthonormal wavelet transform bases proposed by Daubechies.

A generalized, parametric, smooth 2-band PR-QMF design approach based on Bernstein polynomial approximation is developed. It is found that the most regular compact support orthonormal wavelet filters, coiflet filters are only the special cases of the proposed filter bank design technique.

A new objective performance measure called Non-aliasing Energy Ratio(NER) is developed. Its merits …

The Influence Of Junior First Grade On Academic Ability And Self-Concept Of Academic Ability, Mary Ann Boettger

Dissertations

The educational practice of retaining students in junior first grade for a year between kindergarten and first grade was the focus of this study.

Four groups of 1983-1984 students were compared in 1990-1991: (1) those recommended for first and placed in first grade (F-F), (2) those recommended for junior first and placed in junior first grade (JF-JF), (3) those recommended for junior first and placed in first grade (JF-F), and (4) those borderline between junior first and kindergarten, but placed in first grade (B-F).

The groups were compared on gender, birth month, retention, absences, and lunch status, as well as …

Rank Procedures For The Logistic Model, Hung-Ir Li

Dissertations

Dose response assessment using quantal bioassay is a useful statistical procedure, especially in pharmaceutical science. The problem can be written in terms of a generalized linear model. The response of a subject is often dichotomous; that is, either the response or the absence of a response is recorded. The probability of response is related to the dose through a link function. A frequently used link function is the logistic. Statistical problems include fitting the model, confirming the existence of a dose response, and estimation of the ED50, the value of the dose at which the probability of response is 50%. …

Teacher Retention And Teacher Satisfaction In Lutheran Secondary Schools, Cary L. Stelmachowicz

Dissertations

The purpose of this study was to identify the relationship between teacher retention and the nine subscales of the National Association of Secondary School Principals (NASSP) Teacher Satisfaction Survey (Schmitt & Loher, 1986) for teachers in Lutheran secondary schools. Both former and current Lutheran secondary teachers (262) were surveyed to identify sources of satisfaction levels that may induce teachers to leave Lutheran secondary education.

The survey instrument used was the Teacher Satisfaction Survey developed by the NASSP. The survey includes nine subscales of satisfaction: administration, compensation, opportunities for advancement, student responsibility and discipline, curriculum and job tasks, coworkers, parents and …

A Study Of The Effects On Second-Grade Students Of A Leadership Curriculum, Michael Frazee

Dissertations

Investigators of leadership behavior have largely overlooked the period during early childhood when adjustment to the group is initially acquired and practiced. This study was designed to determine whether leadership skills could be taught to second-grade students. The purpose of the research was to determine the effectiveness of the Leadership Is Vital to Education (L.I.V.E.) (Lockett, 1982) leadership curriculum.

A major assumption in this study was that leadership development could be an appropriate outcome of the elementary school curriculum and could be facilitated by introducing a specific leadership-training component into the existing curriculum. The objective was to determine whether the …

Administrative And Faculty Development: A Study Of Academic Chairpersons, Mary Ann Bowman

Dissertations

The professional development of academic chairpersons has been neglected both by higher education institutions and as a field of study. This study focused on assessing both the perceptions of chairpersons toward administrative and faculty development and their degree of participation in development activities and roles.

A survey instrument was designed to make this assessment and was mailed to 311 chairpersons at eight midwestern public universities classified as Doctorate-Granting Universities I. The response rate was 75%, with 234 questionnaires returned .

The results of the survey showed that although chairpersons view both administrative development and faculty development as important, faculty development …

Integrated Anaerobic-Aerobic System For The Biodegradation Of Highly Chlorinated Aromatic Compounds, Cheng-Ming Kung

Dissertations

A two-step process was developed for the complete mineralization of hazardous chlorinated aromatic compounds. The system consisted of an anaerobic reactor, in which reductive dehalogenation took place, coupled with an aerobic reactor in which the complete mineralization of the products of the anaerobic dehalogenation occurred.

A mixed anaerobic culture from a municipal sewage treatment plant was enriched and then immobilized on silica-based porous beads to treat 2,4,6-trichlorophenol (TCP), which is the model target compound in this work. In the anaerobic reactor, TCP was degraded to 2,4-dichlorophenol which was, in turn, reduced to 4-chlorophenol (4-CP). Stoichiometric amounts of 4-CP were recovered …

A Comparison Of Science And Mathematics Achievement, Attitudes, Curricular Experiences, And Career Interest Resulting From Magnet And Traditional High School Programs, Rozana Abdul Razak

Dissertations

The growth of specialized schools that emphasize science and mathematics has raised questions about their efficacy in improving performance in various parameters in mathematics and science. In this study, four different components were compared. A science and mathematics experiences questionnaire determined the type and extent of student experiences in science and mathematics during high school, and student interest in science and mathematics careers. The American College Testing Program (ACT) (ACT Registration) sub-scores assessed scholastic achievement, while the determination of student attitudes towards science used the Scientific Attitude Inventory (SAI) (Moore & Sutman, 1970).

Subjects in the study consisted of three …

A Representation Of Chemical Reactions By Labeled Graphs, Héctor Hevia

Dissertations

Graphs can be used to represent the atomic structure of chemical compounds where the vertices of the graph represent the individual atoms and the edges of the graph represent the valence bonds between a pair of atoms. M. A. Johnson (1991) introduced a graph-theoretic way to represent structural changes in chemical compounds. Thus, certain labelings of graphs called transitional labelings can be thought as representing chemical equations. Associated with these labelings, we introduce a new invariant of a graph G called the transitional value of G. The transitional value of a graph G gives an indication of how dramatic a …

Developing Language Through A Musical Program And Its Effect On The Reading Achievement Of Spanish Speaking Migrant Children, Dora Dominguez

Dissertations

The purpose of this study was to investigate the effects of a language development program that uses music as a medium of instruction on the reading achievement of Spanish speaking migrant children. Fifty-one preschool aged subjects from a Title I (Michigan Department of Education, 1987) Summer Migrant Education Program participated in the study.

The subjects were randomly divided into 2 groups. They were provided oral language instruction to help them acquire the language of the basal readers. In other words, the vocabulary and language patterns found in a basal reading program were built into the daily language lessons. In the …

Transformations Of Graphs And Digraphs, Elzbieta B. Jarrett

Dissertations

Some distances defined on graphs depend on transforming one graph into another. Two of these transformations are edge rotation and edge slide. In this dissertation, extensions and generalizations of these transformations are investigated.

Chapter I begins with some preliminary definitions and known results. Then two types of digraph transformations are introduced and their properties are studied.

Some measures of distance between graphs and distance between digraphs are defined in Chapter II. Also distance graphs and digraphs associated with these measures are introduced. Several known results concerning this topic are generalized and new results are presented.

Chapter III is devoted to …

Surgical Techniques For Constructing Minimal Orientable Imbeddings Of Joins And Compositions Of Graphs, David L. Craft

Dissertations

The various cases within the proof of the Heawood Map-Coloring Theorem, which established the genus of the complete graphs, utilized various techniques--some for the first time. This activity spurred interest in determining the genus of various other classes of graphs. However, very few generally applicable techniques have been developed, beyond those used in the proof of this famous theorem. Finding genera of arbitrary graphs remains a very difficult problem.

In this dissertation, we describe two surgical techniques for imbedding graphs. The first construction, called a graphical surface,views an orientable surface as a fattened graph, i.e., vertices become spheres and edges …

Mathematical Modeling Of Mass Transfer In Microvascular Wall And Interstitial Space, Daekyung Kim

Dissertations

The dynamics of macromolecular transport across the microvascular wall and into the adjoining interstitial space was studied in the hamster cheek pouch using intravital fluorescence microscopy in combination with digital image processing. Fluorescein isothiocyanate-labe led dextrans (FITC-Dx) of 70,000 and 150,000 daltons were used as tracers. In each experiment, the time-dependent extravasation of FITC-Dx from a leakage site in a blood vessel was videotaped for about 2 hours. The macromolecular transport from individual microvessels was quantified by digital video-image processing. Histograms of the light intensity distributions for selected fields at various times were obtained and then converted to the interstitial …

The Theory Of Bootstrapped Algorithms And Their Applications To Cross Polarization Interference Cancelation, Abdulkadir Dinc

Dissertations

Dual-polarized transmission has become an important method for frequency re-use, particularly in satellite and microwave radio communication. Nevertheless, cross-polarization interference, which is inherent to this method, may cause degradation in system performance.

Different canceler [sic] structures have been proposed to mitigate the effect of cross-polarization. Among these are the diagonalizer, the least mean square (LMS) canceler [sic] and the bootstrapped cancelers [sic]. Bootstrapped canceler [sic] schemes have been proposed and implemented in different applications, such as satellites, tactical communications, and quadrature amplitude madulation [sic] (QAM) dual polarized microwave radio. Nevertheless, no attempt was made in the past to quantify the …

Mathematical Modeling Of Chemical Vapor Deposition Processes And Its Application To Thin Film Technology, Norman W. Loney

Dissertations

A number of workers in the field of Chemical vapor deposition (CVD) have presented mathematical models in the literature. Some workers were able to produce analytical expressions for the interwafer concentration profile. These analytical expressions were based entirely on zero or first order chemical reaction rates. Until now, it appears that a chemical reaction rate expression that is not zero or first order directly, must be handled by a numerical scheme.

Presented herein is a mathematical model with an analytical interwafer concentration profile. This concentration profile is neither zero nor first order but shifts from zero to first order as …

Investigation Of Stagnation Flow Heat Transfer For A Heated Horizontal Round Plate, Ching-Hua Wei

Dissertations

The heat transfer characteristics in stagnation flow are investigated through three cases in this study. The first is forced convection by an array of air jets; the second is free convection of a downward-facing heated round plate; the third is free convection of an upward-facing heated round plate.

The first case is investigated by systematic experiments which examine the heat transfer characteristics mainly by five air jets impinging normally to a flat plate, with varying nozzle diameters, and Reynolds numbers, at different distances between the nozzles and the plate. The empirical formulas of heat transfer around the stagnation point and …

Managing Patient Care: A Substantive Theory Of Clinical Decision Making In Home Health Care Nursing, Felicitas A. Dela Cruz Dnsc, Ma, Rn

Dissertations

This study investigates the phenomenon of clinical decision making, deriving a grounded substantive theory to explain how home health care nurses make patient care decisions. Despite the continuing shift of health care from acute care settings to the patient's home, little is known about home health care nurses' clinical decision making processes and the factors influencing them. The study employs a field research design using grounded theory based on symbolic interactionism. Data collection at two Visiting Nurse Associations includes participant observation and open-ended interviews of 21 nurses, and document analysis of patients' records and home care nursing practice policies. The …

Using Technology To Improve Equity Of Curriculum Access For Students In Michigan's Upper Peninsula, Herbert L. Harroun

Dissertations

In this study, the curriculum offerings available to students attending 50 of the 54 high schools in Michigan's Upper Peninsula (U .P .) that responded to the survey were compared to the offerings identified as requisites of a modern comprehensive Michigan high school, particularly in the areas of English and communications skills , social studies, mathematics, science, and foreign languages. Upper Peninsula student enrollment levels in those core curriculum areas in 1989-90 were analyzed to determine the impact the adoption of the course study recommendations in the Michigan K-12 Program Standards of Quality (Michigan State Board of Education, 1987) throughout …

Thermodynamics Of Strong Electrolyte Solutions : Prediction Of Osmotic Coefficients By Pair Correlation Function Method, One Kwon Rim

Dissertations

Thermodynamic properties (osmotic coefficients) of strong electrolyte solutions have been studied by the method of statistical mechanics. First the charged soft sphere potential is developed based on the Pauling type model. Next the charged soft sphere potential is converted to the thermodynamically corresponding charged hard sphere potential by way of the perturbation method developed by Verlet and Weis. Simultaneously, the radial distribution function is developed by modification of the Exponential theory through introduction of the Stillinger-Lovett moment condition. The effective hard sphere diameter values calculated by the perturbation method are combined with the modified Exponential theory, and these quantities are …

On Local Stresses And Spring Constants Of A Sphere-Nozzle Connection, Ban-Li Lyow

Dissertations

This dissertation studies the local stresses and spring constants of a spherical shell with a nozzle attachment when it is under various loadings, namely radial force, overturning moment, horizontal shear force, and torsional moment. Because of the mathematical difficulty in modeling the nozzle-sphere configuration, particularly with nozzle opening, the finite element method (ANSYS package) is utilized in this study. The model used in this study is a quadrilateral thin shell element model when the γ_s (spherical radius/thickness) value is larger than 10. Otherwise the isoparametric solid element is used. The resulting stresses are basically biaxial state of stresses. It …

The Leadership Process And Its Effects On Self-Managed Work Groups In American Manufacturing Companies, Stephen R. Wirkus Edd

Dissertations

Over the past 75 years, leadership has become a widely studied phenomenon, with many theories and models offered to assist the layman to become an effective leader. Most of these theories have been based on management models, that is, models that adapt management behaviors and goals into what the authors call leadership. These theories fall into several categories: great man, trait, contingency and situational among others. While these theories have provided practitioners some valid ideas on how to improve their managerial effectiveness, they have done little in the way of expanding the knowledge of the process of leadership. This study …

An Exploration Of The Determinants Of Attitude Toward Computers In Middle School Students, Earl Wayne Connell Edd

Dissertations

The educational world is belatedly rushing into the world of technology with relatively limited factual information concerning students' attitude toward computers. While most students have a positive attitude, research has indicated that the male is more positive than the female for various reasons. The purpose of this study was to investigate a diverse set of possible determinants of attitude toward computers including sex, ethnic background, learning style, and computer literacy. The subjects were 284 coeducational students from four ethnic backgrounds that attended three middle schools in San Diego. A requirement that subjects have two years of experience with computer assisted …
