Impurity Modes In Photonic Band Structures, Yi-Fen Chang

Masters Theses

In this thesis I study a theoretical model of one-dimensional dielectric array (a layered system of dielectric slabs) which forms a periodic dielectric system in which band gaps are opened in the frequency spectrum. Specifically, we study such a one-dimensional array with linear impurities introduced in the periodic dielectric system. In these impurity structures narrow resonant modes are found in the band gaps as impurity modes and these impurity modes change with the dielectric constant. This impurity problem is similar to the donor and acceptor state problem in electronic semiconductors. The calculations presented in this thesis are based on numerically …

Ground-Water Contamination By Volatile Organic Compounds: Sources Of Error, Temporal And Spatial Variability, Gary Thomas Blinkiewicz

Masters Theses

Data on the distributions of VOC’s (volatile organic compounds), principally trichloroethane and dichloroethylenes, in a shallow sand and gravel aquifer near Rockford, IL have been collected for a number of years. Synoptic sampling events from a dense monitoring well network within a greater than 4 mi^2 area, provide the basis for the evaluation of sources of variability in concentrations in space and time. Sampling, and analysis-related variability in these data contribute less than 10% of total variance. Spatial and temporal variability over periods of months to years are significant Results suggest that contaminant distributions can be resolved best by using …

Improved Filter-Pack Design For Hydrocarbon Recovery Wells In Unconsolidated Aquifers, Thomas R. Barrett

Masters Theses

Laboratory sand tank experiments and two field studies were conducted to determine filter-pack designs that would increase the hydrocarbon flow rate into hydrocarbon recovery wells. Previous laboratory experiments have shown that using filter-packs of Teflon chips or sands treated with a water repellent spray will increase the rate of hydrocarbon recovery into wells in laboratory bail down test experiments.

The results of the laboratory investigations suggest that using a hydrophobic filter-pack with a median grain-size of 2.5-3.5 greater than that of the aquifer will provide the greatest rate of hydrocarbon recovery.

In two field studies, wells constructed with a hydrophobic …

Simulation Model For Predicting The Impact Of Progressive Diseases In The U.S. Population By Tracking, Biju Suseelan

Masters Theses

Computer Aided Simulation is the process of designing a mathematical-logical model of a real system and experimenting with this model on a computer. Simulation encompasses a model building process as well as the design and implementation of an appropriate experiment involving that model. A simulation experiment involves observing the dynamic behavior of a model by moving from state to state in accordance with well-defined operating rules designed into the model. This research contains the development of a novel approach for the HIV transmission dynamics by using computer simulation to track the HIV positive individuals in a population and to determine …

World View, Metaphysics, And Epistemology, William W. Cobern

Scientific Literacy and Cultural Studies Project

It has been argued from world view theory that fundamental beliefs about the world exert a powerful influence on how sense is made of events in the world. However, the nature of that influence has remained enigmatic. Hannah Arendt's distinction between thinking and comprehension, and knowing and apprehension provides a clarification. Thinking is the epistemological path to conceptual comprehension. Knowing is the metaphysical path to apprehension - to the acceptance of a concept as true or valid. Comprehension does not necessitate apprehension. One may reject a fully understood concept. The recent discussion in science education about world view is essentially …

Contextual Constructivism: The Impact Of Culture On The Learning And Teaching Of Science, William W. Cobern

Scientific Literacy and Cultural Studies Project

Though rooted in Piagetian research, constructivism1 is an avenue of research pertaining to teaching and learning that departed from the neo-Piagetian2 mainstream twenty years ago and has continued on a distinct path of development. The departure was evident by the late seventies, clearly marked by two publications, Novak (1977) and Driver & Easley (1978). For constructivists, learning is not knowledge written on, or transplanted to, a person's mind as if the mind were a blank slate waiting to be written on or an empty gallery waiting to be filled. Constructivists use the metaphor of construction because it aptly summarizes the …

The Extent Of Multimedia Computer Applications In The Business World, Mei Yee Lim

Honors Theses

The world, or at least I, was all agog when touch screens arrived. My initial contact with touch screens was at a science exhibition in Menara MPPJ, Petaling Jaya, Malaysia in July 1987. That particular exhibit, which encouraged visitors to participate and to experiment with, was a graphic program. Visitors could use their fingers to select the drawing tool or the color they want (which is something like the tools on a MacDraw screen on a Macintosh) and use their fingers to move around the screen to draw anything they want. That added to my fascination with the world of …

Teachers Reflect On Their Experience As Readers: The Literacy Club Luncheon, Carolyn S. Andrews-Beck, James Rycik

Reading Horizons: A Journal of Literacy and Language Arts

Just as teachers who write are best able to act as guides for less experienced writers (Graves, 1983; Murray, 1985; Calkins, 1991; Atwell, 1985), teachers who see them selves as readers - who are aware of the requirements and strategies of the reader's role - are best able to guide young readers (Smith, 1982; Bleich, 1985; Hansen, 1987). For this reason, it is important for teachers to keep their membership in the "literacy club" (Smith, 1985) current by attending regular meetings.

An Analysis Of The Effect Of Matching Student Learning Style To The Method Of Instruction, Addamae Akin

Dissertations

The purpose of this study was to determine if matching student learning style and teacher teaching style w ill result in any difference in achievement of students in the classroom as measured by the number of students receiving credit in ninth-grade world history classes.

The study was conducted in a mid-size Macomb County, Michigan, school district. Two hundred fifteen ninth-grade students and four teachers participated in this study. World history classes were used because of their heterogeneous grouping and because i t was a required ninth-grade class.

Students were administered the Learning Style Profile (Keefe & Monk, 1986) from the …

An Analysis Of The Utilization Of Power By Florence Nightingale 1856-1872, Louise C. Selanders

Dissertations

This historical analysis sought to determine the types of power utilized by Florence Nightingale while providing leadership to major reforms and how these power acts were implemented- The scope of the study was her productive post- Crimean years from 1856 through 1872. Events which were examined included the reform of the health of the British Army including the Royal Commission, the establishment of modem, secular nursing education and the establishment of public health standards in India during British colonization.

The power acts were examined relative to the constituents of power defined by Dahl (1957). The source of power contained subsets …

Computational Neural Networks In Chemistry: Model Free Mapping Devices For Predicting Chemical Reactivity From Molecular Structure, David Wayne Elrod

Dissertations

Computational neural networks (CNNs) are a computational paradigm inspired by the brain’s massively parallel network of highly interconnected neurons. The power of computational neural networks derives not so much from their ability to model the brain as from their ability to learn by example and to map highly complex, nonlinear functions, without the need to explicitly specify the functional relationship. Two central questions about CNNs were investigated in the context of predicting chemical reactions: (1) the mapping properties of neural networks and (2) the representation of chemical information for use in CNNs.

Chemical reactivity is here considered an example of …

A Study Of Ground-Water Quality In A Priority Agricultural And Livestock Watershed, Cass County, Michigan, Matthew Alan Stuk

Masters Theses

A study of ground-water contamination in a shallow, sandy, glacial drift aquifer was performed in a watershed dominated by swine feedlots and crop fields in Cass County, Michigan. Monitoring wells were installed and sampled to study the flow pattern, chemistry, and contamination of ground water.

Results of chemical analyses show contamination from fertilizers and other soil-applied chemicals as well as the infiltration of breakdown products from pig waste. Shallow wells in impacted areas show potassium and nitrate from the breakdown of fertilizers, calcium from field application of lime, and additional nitrate from pig waste. Elevated calcium, potassium, and nitrate concentrations …
