A Cube As Form, Jeoung-Eun Lim

Theses

Today science and technology has created a mechanized society for all of us. Often I feel alienated by the people around me. This lack of human compassion often casts my spirits into a state of frustration and despair. My work deals with my personal isolation and memories, and with how these entries are boxed-in or enclosed in ways that are ambiguous. Perhaps they can be interpreted as abstract, representational, two-dimensional, threedimensional, or even, in their distortions, hint at unperceived dimensions. Future, past and present are not parts of continuously flowing time, but they are rather three directions or three dimensions …

Integration Of Surfactants And Time Release Nutrients With Pneumatic Fracturing Process, Atiqur Md. Rahman

Theses

The objective of this laboratory study was the development of two novel improvements to the pneumatic fracturing process which would extend its present application. The first involved use of surfactant during pneumatic injection, and the second was subsurface injection of "time-release" dry nutrient pellets for enhancement of in situ biodegradation.

Bench scale tests demonstrated that pneumatic fracturing can be successfully performed with air containing a surfactant solution (foam fracturing). The results showed that foam fracturing followed by increased the rate of surrogate contaminant removal from 8% to 10% compared with regular pneumatic fracturing. These increases were attributed to enlarged fracture …

The Influence Of Hydrodynamics And Particle Size On The Rejection Properties Of Ultrafiltration Membranes, Usama M. Shahin

Theses

A mathematical model based on the flow hydrodynamics is developed to calculate the treatment efficiency of ultrafiltration process. This model relates the treatment efficiency with the consideration of both fixed parameters and variable parameters. The fixed parameters are function of the intrinsic rejection coefficient, diffusion coefficient, and viscosity whereas the variable parameters can be related to the fluid velocity, volume flux, and cartridge dimensions. The model has been examined by solutions with solutes that have different molecular weights. The experimental data fits the proposed mathematical model very closely suggesting its suitability to evaluate the rejection efficiency in ultrafiltration. As such …

The Use And Evaluation Of Cleaner Wicks To Accelerate In Situ Bioremediation Of Organically Contaminated Groundwater And Soil, Brian Michael Sielski

Theses

The adaptation of Cleaner Wicks to accelerate in situ bioremediation of organically contaminated ground water and soil can be accomplished by making minor modifications to the Cleaner Wick design.

Once these changes in the Cleaner Wick design have been made the two primary ingredients necessary for aerobic microorganisms, nutrients and oxygen, can be delivered via the Cleaner Wick to the subsurface environment both above and below the water table to stimulate microbial growth and activity. Therefore, the microbial population will be able to biodegrade the target contaminants, rendering them harmless products such as carbon dioxide and water.

Cityscapes: Solitude And Introspection, Fred G. Monti

Theses

The paintings, in this series, deal with the psychology of the urban landscape. Sky lines, night scenes, and the human figure were examined. City structures, inhabitants, and the elements which make them up, become symbolic: catalysts for contemplation. The commonplace becomes metaphysical. The city is a foreign vacuum; a spiritual nomads land. Buildings, bus shelters, steel and glass become a compositional prison. Like an enigmatic halfway house, we have entered urban limbo. This group of paintings is a commentary on such imagery. Specifically, they are visual impressions of its numbing effect on the human psyche.

Form As Symbol: Allure And Defense, Alexandra Hart

Theses

In my thesis, I explore some recurrent ideas which I have become aware of in my work. The central idea of the work is to explore my fascination with the beauty that I find in organic form, specifically forms in nature which have a defensive function. Though the function of my work is not to defend, I explore the form itself in terms of its visual impact on the viewer. Another component of the work is my attempt to reconcile my respect and admiration for the jewelry that has been done in the past with the contemporary emphasis on creating …

Automatic Visual Inspection Of Placement Of Bare Dies In Multichip Modules, Mahesh Chheda

Theses

Multichip Modules are gaining lot of popularity in today's IC technology, as they are good solutions for high density packaging. This thesis presents a method for checking the placement of bare dies on a common substrate of an MCM. This testing is done using Automatic Visual Inspection (AVI), which is better and more reliable, compared to manual inspection. Comparison is the basis in this thesis to detect faults in an MCM. The MCM to be tested is compared with a known good ideal MCM using image processing techniques. The mismatches, if any, between these two images, i.e. image of an …

Fuzzy Approach For Arabic Character Recognition, Adnan El-Nasan

Theses

Pattern recognition/classification is increasingly drawing the attention of scientific research because of its important roll in automation and human-machine communication. Even though many models have been introduced to deal with classification, because of the inherited imprecision and ambiguity, these models did not tackle the problem in an efficient way. Traditional models deal only with statistical uncertainty (randomness) but not with the non-statistical uncertainty (vagueness). Fuzzy set theory allows us to better understand imprecision in both of its categories: vagueness and randomness. The incorporation of fuzzy set theory in existing algorithms helped in many cases to improve the performance and increase …

Computational Analysis Of The Flow Field In A Baffled Mixing Tank, Daniel C. Kellem

Theses

The fluid motion in a mixing tank was studied using a CFD code. The particular focus was given to the accurate representation of the role of baffles in a mixing tank. By rebuilding the boundary conditions at each time step the complete effects of the relative motion between the baffles and impeller is captured. This has allowed for an accurate Computational Fluid Dynamic representation of the flow in a baffled mixing tank. In addition, the development of the model has been automated through the use of geometry and mesh definition files. The combination of these two aspects has allowed for …

The Generation And Comparison Of Multispectral Synthetic Textures, Robert A. Rose

Theses

The Musique Multispectral Texture (MMT) model is a method of adding realistic multispectral textures to synthetic images created using DIRSIG (Digital Imaging and Remotes Sensing laboratories Image generation Model). This method relies on an input texture image and a large family of reflectance curves which represent the desired texture material. This thesis has two main objectives. The first is to determine the best method of generating the input textures, and the second is to test the quality of the multispectral textures generated by the MMT model. The testing will involve both statistical and human visual analysis. The thesis intends to …

Visual Assessment Of Object Color Chroma And Colorfulness, Jason Peterson

Theses

A series of visual experiments were designed to determine whether naive observers typically evaluate chroma or colorfulness when judging color appearance. A total of 7 observers were asked to determine a color appearance match between Munsell samples under the same illuminant (C) at different levels of illuminance. Color appearance matches were determined for 12 Munsell samples, under five reference and matching scene illuminance conditions, for four experimental techniques. The four experimental techniques were haploscopic, simultaneous inspection, successive inspection, and short-term memory matching. Results suggested that a chroma match was most important when observers were evaluating the color appearance of two …

The Synthesis And Characterization Of A Bis(4-(3-(4-Phenoxy)Propionitrile))-N,N'-Disalicylidene-1,2-Phenylenediamino)Zirconium(Iv),Zr(Nitrile)2 And The Attempted Sythesis Of Zr(Amine)2 And Coordination Polymers Contaning Zr(Dspoh)2, Kathy-Jo Brodsky

Theses

The synthesis of a series of bis(quadridentate)zirconium(IV) complexes, that can be considered as derivatives of the model complex, bis(N,N'-disalicylidene-l,2-phenylenediaminozirconium (IV), Zr(dsp)2, was conducted in order to produce zirconium coordination complexes with reactive terminal groups that would undergo ligand centered polymerization reactions. The previously reported Zr(dspOH)2 complex and the previously unreported Zr(nitrile)2 (shown below) and Zr(amide)2 complexes were synthesized, purified and characterized by FTIR, *H NMR and elemental analysis. The attempted polymerization reactions of Zr(dspOH)2 with diacid chlorides did not yield the desired linear coordination polymers. The attempted reduction of Zr(nitrile)2 to Zr(amine)2 was not successful via catalytic hydrogenation or chemical …

Image Transformation Into Device Dependent Color Printer Description Using 4th-Order Polynomial Regression And Labview Object Oriented Programming Development Of Image Processing Modules, Michael Mongeon

Theses

This thesis investigates the development of printer device profiles used in color document printing system environments when devices with intrinsically different gamut capabilities communicate with one another in a common (CIELAB) color space. While the main thrust of this activity focuses on the output printer, namely the Xerox 5760 printer, and its rendition of some device independent image description, characterizations are provided which investigate relative areas of photographic, monitor, and printer gamuts using a visual hue leaf comparison between devices at standard hue angles determined from a Kodak photographic Q60C. The printer is modeled using 4th-order polynomial regression which maps …

Color Reproduction Of Crt-Displayed Images As Projected Transparencies, Audrey A. Lester

Theses

This thesis evaluated the color appearance predictions of four digital color transforms (Hunt, RLAB, CIELAB, and von Kries) between CRT "original" images, viewed in a lighted room, and projected slides, viewed in the dark. Calibrated projection of these images required resolution of several complex issues. Upon projection, the slide colors changed. A rapid color shift (on the order of 75 seconds) was followed by a slower, steady degradation which also had to be minimized for accurate image presentation. Therefore, a model of the film behavior was based upon dye absorptivities and color measurements of slides as they were projected. The …
