Transient Performance Of Parallel-Flow And Cross-Flow Direct Transfer Type Heat Exchangers With A Step Temperature Change On The Minimum Capacity Rate Fluid Stream, Brian D. Cole

Theses

Parallel and cross-flow with both fluids unmixed, direct transfer type heat exchangers are modeled utilizing a thermal network consisting of nodes and resistors. A commercially available software package, Thermonet, calculates the transient outlet temperatures for a steadystate model introduced to a sudden change (step input) in inlet temperature of the Cmin fluid stream. Both models are validated against analytical solutions provided in literature. Solutions are verified to within a maximum percent mean difference of 4 % of analytical solutions for parallel-flow, and 8 % of analytical solutions for cross-flow heat exchangers. Tables are generated which provide new dimensionless transient outlet …

Signal Detection Using Pseudocolor Scales, Hong Li

Theses

Historically, gray scale has been the standard method of displaying univariate medical images. A few color scales have been proposed and evaluated, but have had little acceptance by radiologists. It is possible that carefully desired scales might give lesion detection performance that equals gray scale and improves performance of other tasks. We investigated 13 display scales including the physically linear gray scale, the popular rainbow scale and the other 1 1 perceptually linearized scales. One was the hot body (heated object) scale and the other 10 were spiral trajectories in the CIELAB uniform color space. The experiments were performed using …

An Artist's Guide To Four-Color Printing: A Prototype Of A Guide To Educate Artists About Four-Color Offset Printing, Whitney Miller

Theses

Occasionally artists need to have their artwork reproduced. The problem is that most artists do not understand what is involved in the four-color prepress and printing processes and, because of this, do not know how to communicate with printers. Artists often do not realize it is very difficult to make an exact copy of their artwork when it is reproduced by four-color offset lithography and are disappointed with the final printed product. The objective of this thesis project is to educate artists about four-color printing so they can communicate more effectively with printers. A prototype for a booklet entitled An …

A Field Study To Determine The Feasibility Of Establishing Remote Data Transmission Of Advertising For A Local Newspaper, John Mckeever Jr

Theses

In recent years, local newspaper's advertising revenues have been seriously eroded by the presence of competing electronic media. Technological innovation in cable television (CATV), interactive multimedia, broadcast television and Compact Disc-Read-Only Memory (CD-ROM) have proven to be a double-edge sword for local newspaper advertising revenues. On one hand, these technologies provide lower cost, high quality advertisement which target larger, more diverse audiences. On the other hand, the same technological innovations (high speed digital transmission, high quality input and output devices, and the widespread use of portable computing) have created a means for local newspapers to protect their advertising base and …

Moving Toward Reconciliation, Paula Boronell

Theses

My thesis concept had originally been concerned with gender role playing and the effect this role playing has on the individual. As the work progressed, however, my original concept slowly evolved into something more personal. "Moving Towards Reconciliation" was really about resolving my own questions, and being reconciled with the answers I found. This thesis report describes the route which took me from abstract concept to a personal reconciliation.

Synthesis Of Boron Nitride/Vycor Composite Membrane Structures By An Optimized Lpcvd Process, Chenna Ravindranath

Theses

Since the advent of the idea of ultrafiltration, microporous membranes have come through a long way in establishing a niche as an efficient technology for gas separation applications. More and more research is aimed at reducing pore size towards nanolevels, when separation factor is the criterion rather than the permeability. This work is focused at synthesizing and characterizing microporous inorganic membranes for gas separations by molecular sieving. BN was deposited on mesoporous vycor tubes using triethylamine borane complex (TEAB) and ammonia as precursors. Effect of temperature and deposition geometry on permeability of various gases has been studied. Very high selectivities …

Investigation Into Fracture Behavior And Longevity Of Pneumatically Fractured Fine-Grained Formations, Heathe Ann Hall

Theses

This study investigates volume changes in fine-grained soil formations and their effect on pneumatically induced fractures. Pneumatic fracturing is an enhancement technology for in situ remediation of hazardous waste sites, which increases the formation permeability by creating fractures. A number of formation properties and environmental conditions which affect fracture aperture were identified in this study.

Laboratory experiments were performed with control devices to investigate idealized fracture flow under linear and radial flow geometries. These tests exhibited cubic law behavior, and gas compressibility was seen as a measurable effect. A horizontal infiltrometer device was successfully developed to induce and control volume …

Reverse Osmosis As A Pretreatment Of Ion Exchange Equipment At Pse & G'S Hudson Generation Station, Steven Leon

Theses

Public Service Electric and Gas Company's Hudson Generating Station has historically had problems providing sufficient high quality water for its two once through, supercritical design boilers. The station requires over 60 million gallons annually to compensate for system losses.

The stations' ion exchange demineralizers proved to be costly to operate and overall inefficient in performance. Drawbacks include: short service cycles, periodic contamination of storage tanks due to premature breakthrough, prohibitively high chemical regenerant costs, excessive labor requirements, frequent resin replacement, and overall unreliable plant operations.

A reverse osmosis unit was installed as a pretreatment to the demineralizers to offset these …

Simulation Of A Neural Network-Driven Fuzzy Controller, Karl Ver Schneider

Theses

A software simulation package was developed to facilitate the analysis of a fuzzy logic tracking system constructed by first training a neural network. The adaptive vector quantization neural network used a competitive learning algorithm to classify control data from a controller in a noisy environment. The neural network memory generated rules for a fuzzy controller by mapping the state of the network into a predetermined fuzzy database. The software is intended to be expanded to allow further analysis of neural dynamics and to compare the performance of the resulting fuzzy controller to conventional controllers.

Spectroscopic And Sensitometric Studies Of Chemically Produced Silver Clusters, Shilin Guo

Theses

This thesis research uses 0.45 urn octahedral AgBr emulsion to study chemically produced silver clusters. Reduction sensitization has been carried out with DMAB, SnCk, and NaOH. The progress of the reaction has been monitored both with sensitometry and diffuse reflectance spectra of the chemically produced silver clusters. The reflection minimum occurs at about 476 nm, independent of reagent. The absorbency by these clusters, derived from the Kubelka-Munk transform, is related to the concentration of the sensitizing agent. Exposure to light causes a decrease in the absorbency by these silver clusters, indicating that some of the silver clusters are hole traps. …

Neural Network For Optimization Of Binary Computer-Generated Hologram With Printing Model, Guo Li

Theses

Hopfield neural nets are used to optimize point-oriented binary computer-generated holograms (CGHs). It can be considered as a parallel and iterative 'halftoning' process in the spatial frequency domain. The results are comparable to other iterative methods but require shorter computation times. In this process, the generation of the CGH by FFT, binarization, and IFFT is viewed as a "black box" with inputs and outputs consisting of 512 arrays containing an object of size 64 . The neural-network optimization feeds back the Fourier transform of the reconstruction error to update the neuron states, which correspond to the samples of the continuous …
