Comparison Of Methods Of Mtf/Otf Analysis For Optical Systems, Jean Croteau

Theses

A comparison study for the methods of obtaining the MTF of optical systems was performed. It is demonstrated that non-Fourier methods are as good predictors of the MTF as are the Fourier methods. A new technique based on the moment theorem is introduced and is found to be a good predictor. A computer algorithm has been written to perform all the necessary operations.

Design Of A Photoreactor For The Oxidation Of Toxic Pollutants In Water By Ozone And Ultraviolet Radiation, Shahab Rashid Khan

Theses

A photoreactor has been designed to oxidize refractory chemicals found in water using ozone and ultraviolet radiation. The feasibility of the ozone/UV process has been examined by conducting experiments with three model compounds, namely, (1) o-chlorophenol (2) m-chlorophenol and (3) p-chloro phenol. For o-chlorophenol and p-chloro-phenol, reactions were very fast with ozone/UV oxidation and somewhat slower with m-chlorophenol. It is concluded that UV irradiation increases the decomposition of ozone and the resulting unstable intermediates are much more reactive than ozone. Ultraviolet light also helps in decomposing the substrate molecules. The effect of UV upon decomposition of ozone is more pronounced …

To The Best Of My Abilities, Barry Warren Kaiser

Theses

The basic intention of my work is to visually represent concepts through juxtaposed images. The concepts I represent may be elementary, but this does not limit the relationships between images, which may be highly complex. The inspiration for the linkage between images commences intellectually, but because I wish to create unique, and visually appealing pieces, I also deal with the evocative qualities of these juxtapositions.

Radiation Heat Transfer Analysis Of A Czochralski Furnace With A Radiation Shield, Frederick A. Merz

Theses

This paper reports on the radiation heat transfer from the melt in a Czochralski crystal growing furnace in the presence of a radiation shield The change of radiation heat transfer effects three basic areas, the cooling rate of the crystal, the bulk flow and the bulk temperature of the melt. The shield is installed above the melt to inhibit the heat transfer from the melt to the cooling crystal, allowing the crystal to grow 40% faster. Radiation is the primary mode of heat transfer in the furnace where the temperature to grow silicon crystals is around 1773K. The governing equations …

Deposition Of Particles In Horozontal Parallel Plate Channel Due To Image Charge, Inertia, Viscosity And Gravity, Chi-Young Chu

Theses

This investigation was made to determine the effect on the deposition of particle in a horizontal parallel-plate channel due to the influences of image charge, viscosity, inertia and gravity. The flow considered was lamina, incompressible and steady. The flow patterns considered were uniform and fully developed with symmetry about the axis of the channel.

The governing equations derived for a particle were based on Newton's Second Law of motion. Since the resulting governing equations are linear second order differential equations, Runge-Kutta algorithm is used to solve the problem and graphical techniques is used to interpret the results of the numerical …

A Study Of The Halftone Dot Characteristics Of Rapid Access Halftones, John Gilliatt

Theses

Rapid access processing is a photographic processing method that combines high temperature processing and high energy developing agents to obtain very short induction periods, and thus, reduced processing times. In order to obtain maximum quality from the process, the rapid access halftone percent dot areas must be correctly evaluated according to established aim points. Traditional evaluation methods, either visual or instrumental, produce errors. These errors are the partial result of the unique dot characteristics of the process. These characteristics include soft, fringed dots; dots with low Dmax, found particularily in the shadow areas; loss of dot area on the tips …

The Effects Of Shadow Visibility On Image Interpretability, Lawrence A. Maver

Theses

An empirical approach to measuring and predicting the effects of target scene shadows on image interpretability is described. A simulated aerial imagery data base is utilized to quantify image interpretability and computed graphics form the basis of the predictor algorithms. A technique to quantify the relative visibilities of individual line segment images is developed. Three categories of predictors are proposed and utilize line segment visibility to predict image interpretability. The success of the algorithms are tested using regression analysis procedures.

The Pot As Nurturer: An Approach To Functional Pottery, Marian L. Baker

Theses

What is meant by life in pots? Animals drawn on the sides? Arms and legs sprouting out from the clay walls? a big face on the side like those horrible mugs you see in tacky gift shops? Is it a quality in the throwing? A tiny piece of clay frozen out of place on the wall? A fat round shape that may speak of pregnancy or over-eating? Gooey slip dripping off the sides? A distorted portion: lip, foot, wall? A disoriented pot, leaning on its left foot? A drunk pot, ready to fall over? It it none of these, but …

Effect Of Title Iv-B Funding In St. Charles County Public Libraries, 1976-1982, Lucinda Menkhus

Theses

In 1974 Congress consolidated several existing educational programs into the Elementary and Secondary Education Act Title IV. Part B of that bill was designed to provide instructional materials for schools. A majority of Title IV-B money nationwide was used to purchase library books, audiovisual hardware, and audiovisual software.

This study was designed to examine the possible benefits Title IV-B funding had on St. Charles j County school libraries. Between 1976 and 1982, 15 school libraries were able to meet Missouri State standards in the size of the collection category. This study was needed to show that Title IV-B played an …

Geometric Abstract Design, Sanghye Han

Theses

This thesis is a presentation of four grid designs. They are woven on a multi-harness loom and utilize a strip-weaving technique. The designs are based on a series of colors, and consist of three grid elements; the line, the square and the rectangle. Through the variation of colors and the repeated arrangement of patterns consisting of the aforementioned grid elements, my intention is to have a form of geometric abstraction result from my designs.

Second Order Coherent Power Spectra, Brian A. Gorin

Theses

The relationship between second order stochastic processes and coherent power spectra are explored for developed grain size frequency distributions of silver halide emulsion/developer combinations. Although Wiener spectra represent incoherent power spectra, the coherent case has been unresolved due to the difficulty of filtering the optical system effect. The emulsion plates were exposed with a uniform irradiance distribution from an incoherent tungsten source to create a series of uniform density samples. Conventional processing chemistry is utilized with substitution of different developer types, from predominantly physical development to direct chemical development. The exposed and processed density samples were liquid gated with refractive …

Technology In The Late Twentieth Century: Humanism Versus Technocracy, A Philosophical Inquiry, Peter Moss Handler

Theses

As an artist in metal living and working in the last part of the twentieth century, I feel it to be important that my work relate to this specific period of time. That is, to look where we are going becomes more important than where we have been. The most powerful single influence on where we are going, in my judgment, is technology. The images of technology, not the things of it, become my starting place. My intent, however, is not merely to celebrate technology. That is an uncritical attitude.

Synthesis Of Mono- And Dialkyl Catechol Ethers, Sujitra Dhumrongvaraporn

Theses

Estabrook and coworkers have developed an enzymatic analysis for the oxidation of catechol depicted in Figure 1b. The rate of this oxidation (k₂) is so high that the

[Figure 1.]

rate of the O-dealkylation reactions of monocatechol ethers (k₁) may perhaps be conveniently followed by monitoring catechol concentrations as it is produced. That is with k₂ >> k₁, a combined dealkylation and oxidation enzymatic system might be developed to provide kinetic data on step 1, ie. on k₁ values.

With this in mind, a series of appropriate substrates ie. O-monoalkyl catechol ethers needed …

A Model To Predict The Reflectance From A Concrete Surface As A Function Of The Sun-Object-Image Angular Relationship, George C. Grogan

Theses

A study was made of the variation in the reflectance of a concrete sample as the sun-object-image angular relationship was varied. The research work was performed in the controlled conditions of a laboratory so that atmospheric effects could be neglected. Reflectance measurements were taken from a. concrete sample whose surface roughness had been measured. Both specular and diffuse illumination in the red (630 - 680nm) wavelength region of the visible spectrum were measured. A model which can be used to predict the reflectance value for a given sun-object-image angular relationship was developed. Actual reflectance measurements taken outdoors agreed to within …
