Contextual Trappings: A Strategy Of Contradiction, Richard Metzgar

Theses

The focus of this thesis is to examine a multiplicity of ideas in which the presence of contradiction is the unifying component. This "process" of examination has been decidedly "expansive." I am emphasizing process and expansive because these terms could best describe the underlying philosophical attitude driving this body of work; process in relation to both conceptual as well as material considerations. Conceptually, I have given myself the opportunity to examine a broad range of issues, understanding the realization that all levels of worldly stimuli become raw material for an artistic statement. Similarly, in regards to material approaches, selecting the …

The Effects Of Deinking On The Coating Compounds Used On Carbonless Business Forms, Brooke Merrill Tinney

Theses

The purpose of this study was to determine what effects different deinking processes have on the coating compounds used on carbonless forms. Three deinking processes were studied: repulping without deinking chemicals or bleach, deinking using deinking chemicals only, and deinking using both deinking chemicals and bleach. None of the processes were successful at completely removing the oil, which is located in the microcapsules, or the resin, which is used to coat the coated-front portion (CF) of the carbonless form. Of the three deinking processes studied, simple repulping was most effective at eliminating the resin used in the coatings, while the …

Investigation Of Observer Variability Using A New Method For Determining Color Matching Functions, Amy D. North

Theses

The Munsell Color Science Laboratory has developed a new method for determining color matching functions. It relies on a mathematical model that expresses color matching functions as the product of linear transforms of the cone action spectra and variable transmittances of the lens and macula for each observer. With this model, the full spectral tristimulus functions can be computed from a minimum of five visual matches. A visual colorimeter was designed to implement the MCSL model. The current instrument utilizes CRT primaries and seven interference filters to make matches to simulated daylight in a 2 bipartite field. The system was …

Synthesis And Characterization Of Maleimide-Based Polymers, Hua-Chin Chen

Theses

This study concerns the synthesis and characterization of maleimide-based monomers and polymers. N-phenylmaleimide, 4'-N-maleimido-2,3'- dimethylazobenzene and N-p-chlorophenylmaleimide monomers were formed by imidizing maleic anhydride with aniline, 4'-amino-2,3'-dimethylazobenzene and p-chloroaniline, respectively. But N-nitrophenylmaleimide monomer was produced from the nitration of N-phenylmaleimide monomer. The two homopolymers, poly-(N-p-chlorophenylmaleimide) and poly-(Nnitrophenylmaleimide), were synthesized by solution polymerization in toluene solvent. Poly-(Styrene-co-N-phenylmaleimide) and poly-(Styrene-co-4'-Nmaleimido- 2,3'-dimethylazobenzene), each with compositions of [50:50] and [92:8], were produced by imidizing maleic anhydride constructing commercial poly-(Styrene-co-maleic anhydride); [50:50] and [92:8]. Styrene and Nphenylmaleimide monomers were copolymerized in both solution and emulsion to form poly-(Styrene-co-N-phenylmaleimide). Likewise, styrene and 4'-Nmaleimido- 2,3'-dimethylazobenzene were copolymerized …

Direct Recovering Of Surface Structure Characterized By An Nth Degree Polynomial Equation Using The Uoff Approach, Mazen A. Salhi

Theses

There are two different approaches for estimation of structure and/or motion of objects in the computer vision community today. One is the feature correspondence method, and the other is the optical flow method [1]. There are many difficulties and limitations encountered with the feature correspondence method, while the optical flow method is more feasible, but requires a substantial amount of extra calculations if the optical flow is to be computed as an intermediate step.

Direct methods have been developed [2-4], that use the optical flow approach, but avoid computing the full optical flow field as an intermediate step for recovering …

Automation Of Part Inspection In A Coordinate Measuring Machine, Madhu N. Kanoor

Theses

Some of the drawbacks in inspecting a part using a Direct Computer Controlled Coordinate Measuring Machine are that a programmer has to generate a part program for the inspection process, and such programs have to be generated for each part to be inspected. These programs will be restricted to a kind of CMM, thus preventing the portability of the program t o other kinds of CMM.

If a part program can be generated off line after a part has been designed in a CAD system. an operator can inspect the part without any prior knowledge of the esoteric CMM programming …

Biodegradation Of Phenol And 4-Chlorophenol Using A Single Species In A Sequencing Batch Reactor, Kung-Wei Wang

Theses

Biodegradation of phenol and 4-chlorophenol (4CP) using Pseudomonas putida (ATCC 17514) was studied in batch and sequencing batch reactors. Batch experiments were first performed in order to reveal the kinetics of biodegradation for each substrate. 4-Chlorophenol was degradable only in the presence of phenol, or immediately after exposure of the organism to phenol. It was postulated that an enzyme induced by the presence of phenol was necessary to initiate degradation of 4-chlorophenol.

A mathematical model was then developed to describe the dynamic behavior of both substrates in a sequencing batch reactor (SBR). The model utilized rate parameters obtained from batch …

Broadband Isdn Control Using Neural Networks, Stavros Zervoudakis

Theses

Broadband Integrated Services Digital Networks (B-ISDN) are considered to become the standard communications networks in the near future. Major research efford is being applied in determining the appropriate mode of operation for B-ISDN systems. Two proposals, the Synchronous Transfer Mode (STM) and the Asynchronous Transfer Mode (ATM) claim to best fit the B-ISDN transmission requirements individually. A new method for B-ISDN traffic control is proposed in this paper. This method assigns priority levels to incoming traffic while integrating STM with ATM. A neural network is used to decide how the multiplexing of the incoming packets will be performed. Several traffic …

Delay Performance Of Cebus And Modified Cebus Schemes, Altaf Hussain

Theses

In this thesis the performance of the CEBUS (Consumer Electronics Bus), a local area network proposed by the Electronics Industries Association for the 'Smart House,' is analyzed under varying network load and traffic patterns that would occur in a typical home environment. Reduced complexity versions of the CEBUS scheme are compared with the standard CEBUS scheme.

It was found from simulation analysis that the delay in the CEBUS network, at a given network bandwidth, is dependent upon the message priority and the traffic pattern in the network. It was also observed that the performance of a modified CEBUS scheme was …

A Common Application Model For Interfacing With Advanced Program To Program Communication/Vm, Joseph Viviano Jr.

Theses

The Merrill Lynch data processing environment is composed of a conglomeration of applications which reside on various platforms. LAN and minicomputer based applications coexist with those making their home in the mainframe arena. Unfortunately, coexistence does not imply cooperation, data uniformity, data centralization or coordinated application development. Within the Merrill Lynch mainframe arena alone there are two operating systems which reside across several computing complexes, MVS (Multiple Virtual Storage) and VM (Virtual Machine). Critical business applications and data are unique to each of these environments. The problem lies in the need for cooperative processing and sharing of distributed data among …

Costume As Art, Gretchen Lapp Hamlin

Theses

Any given article of clothing can be seen as falling somewhere along a broad continuum that stretches between the completely functional and the completely decorative. On one end of the spectrum, utility dominates; military clothing, designed to promote uniformity and to maximize human performance, might define this extreme. On the opposite pole, function is totally disregarded in favor of pure adornment, even flamboyance - say, Carmen Miranda's hat.
