A Better Environment For Disabled Children, Hyun-Sook Lee
Simplicity, Angela Stickell
Simplicity, Angela Stickell
Theses
My thesis work is intended to be part of an ongoing polemic concerning the value of modernism. Modernism occurred at a time in history when craft, industrial design and architectural design were enjoying reciprocal influences. Many architects were translating their architectural value systems into object designs, many of which became landmarks of twentieth century design. This crossover between the fields, which is evidenced still today, produced a rich theoretic tradition from which to draw. I am convinced that architectural design and object design are invariably linked and this is reflected in my thesis works as well as in my thesis …

Two-Dimensional Spectrum Estimation Using The Radon Transform, Jennifer Wideman
Two-Dimensional Spectrum Estimation Using The Radon Transform, Jennifer Wideman
Theses
An alternative approach to two-dimensional power spectrum estimation incorporating the Radon transform in conjunction with each of the one-dimensional periodogram, Blackman-Tukey, and Autoregressive parameter estimation algorithms is examined. The Radon transform is used to express a two-dimensional data set in terms of its projections onto a set of one-dimensional radial lines, effectively reducing the two-dimensional estimation problem to a series of one-dimensional problems. The resulting two-dimensional power spectrum estimates are compared to the known power spectra for a variety of data types. The Radon transform approach combined with autoregressive parameter estimation can provide a high-resolution power spectrum estimate, effectively surpassing …

A Nonprofit's Guide To Internally-Planned Successful Print Communications, Joseph Wilson
A Nonprofit's Guide To Internally-Planned Successful Print Communications, Joseph Wilson
Theses
Nonprofit institutions, sans a large budget allocated towards design, publications production and printing, suffer from a lack of effective print communications. Even within the classification of "nonprofit," a distinction can be made between successful groups and struggling ones. To further compound the matter, nonprofit groups, beyond just a deficit of funds, lack a graphic artist's understanding of how to assemble, produce and intelligently purchase print communications. It is no wonder then, that the struggling nonprofit group finds itself caught in a frustrating cycle. They need, desperately, to get their word out in order to raise funds; yet they lack the …

Electronic forms is an emerging market that is being incorporated into daily use in many corporations and small businesses. In the transition from paper forms to electronic forms many users are merely recreating the paper forms digitally to create an exact replica on screen. This is being done through the utilization of page layout programs such as QuarkXpress and PageMaker as well as through the aid of electronic forms software programs available today. These software programs aid the user with forms design, often providing templates of forms that are in a graphical format containing rules, logos, and other graphically embellishing …
A Study Of The Relationship Between Optical Dot Gain And Mechanical Dot Gain Of Am And Fm Halftones, Eva Gronberg
A Study Of The Relationship Between Optical Dot Gain And Mechanical Dot Gain Of Am And Fm Halftones, Eva Gronberg
Theses
FM screening differs from conventional screening by the absence of screen ruling and the use of small micro dots to represent the tonal values in an image. FM screens have a high dot gain which is comparable to the dot gain of very fine conventional screens. Some tests showed that FM screens are more stable on press compared to AM screens, that is, they experience less variation in dot gain when the solid ink density is increasing. The major questions of this study were: 1) What is the relationship between mechanical and optical dot gain for FM screens? Is the …
Image Quality Metrics And Optimum Focus Criteria For Visual Optical Systems, Xiaoxue Cheng
Image Quality Metrics And Optimum Focus Criteria For Visual Optical Systems, Xiaoxue Cheng
Theses
Image quality metrics for visual instruments were examined in terms of their through focus behavior in the presence of various aberrations, and their correlations with available subjective performance data. The contrast sensitivity measurements were performed using rotationally symmetric, variable contrast difference-of-gaussians (DOG) targets, viewed through specially designed telescopes that presented various amounts of monochromatic aberrations. Then the contrast sensitivity ratios were correlated with the image quality metrics of the telescopes. The results show that an appropriately defined integral of the instrument-observer MTF (called MTFa) correlates well with subjective performance in most cases and predicts the optimum focus best; the radius …

Catalyzed Additions To Alkene Double Bonds: (I) Fumarase-Catalyzed Hydration Of Alkene Double Bonds (Ii) Alumina-Catalyzed Hydrochlorination Of Alkene Double Bonds, Charles Francavilla
Theses
The stereospecific hydration of (5)-malate to fumarate, catalyzed by fumarase, was extensively analyzed by NMR. The NMR techniques employed were one dimensional 2H and NOE Difference, and two dimensional ^^H COSY. Various potentional substrates were tried for fumarase-promoted hydration with no sucesss. It was concluded that mesaconate is possibly the largest molecule that can fit into the active site of fumarase in the correct orientation for hydration to occur. Thionyl chloride and appropriately prepared alumina was found to promote the addition of HC1 to norbornadiene ( I ), resulting in71%(+l%) exo-5-chloronorbornene ( II ) and 29% 3-chloronortricyclene ( HI ) …

Time-Frequency Distribution Analysis Of Heart Rate And Blood Velocity Variabilities In Stage 24/34 Chick Embryos, Andrew Bonacci
Time-Frequency Distribution Analysis Of Heart Rate And Blood Velocity Variabilities In Stage 24/34 Chick Embryos, Andrew Bonacci
Theses
Time-frequency distribution (TFD) analysis is a relatively new process for decomposing a complex signal to understand its spectral content Traditional signal spectral analysis examines both temporal and spectral contents distinctly. This method of analysis is suitable for signals where the spectral content is stationary and time-invariant. However, many naturally occurring signals are not only multicomponent, but are also highly time-variable, such as speech, heart rate variability, and other biological signals. Typically, the Fourier transform exposes sinusoidal frequencies present in a signal. It cannot, however, tell when these frequencies existed temporally. This is where timefrequency analysis excels over traditional spectral processing …

Removal Of Volatile Organic Compounds From Contaminated Groundwater By Pervaporation, Sukla Chandra
Removal Of Volatile Organic Compounds From Contaminated Groundwater By Pervaporation, Sukla Chandra
Theses
Effective removal of non-aqueous phase liquid pools in groundwater and volatile organic compounds (VOCs) from contaminated soils can be achieved by surfactant flushing. This surfactant-rich ground water contains VOCs like trichloroethylene (TCE), dichloroethylene (DCE), etc. Membrane pervaporation technique is employed here to remove TCE from these micellar systems where a very high percentage of the VOC is trapped inside the micellar core. The micellar solution flows through the bore of microporous hydrophobic hollow fibers wherein the micelles break down and release the surfactants and the TCE. The TCE is then removed through the pores and a nonporous thin silicone skin …
