Thermal Oxidative Decomposition Of Chlorobenzene In A Tubular Flow Reactor, Jian Liu

Theses

The thermal reaction experiments of chlorobenzene decomposition were carried out in a tubular flow reactor in hydrogen and oxygen mixtures ranged from 1% to 5% at one atmosphere total pressure. Experiment temperatures were varied over a range of 590--640°C. Residence times ranged from 0.3 to 2.0 seconds.

It was found that the decomposition of chlorobenzene increased with both temperature and residence time. The oxidation of chlorobenzene occurred more rapidly when oxygen concentration was increased. 95% decomposition of chlorobenzene occurred at 620°C, O₂/H₂ = 5%, and two seconds residence time.

The major products were benzene and HCl, and …

Effect Of 2,3-Butanedione Monoxide On Whole-Cell Potassium Channel Currents In Rat Single Myocytes, Youliang Zhou

Theses

The patch clamp technique is a simple procedure which can isolate ion channels on cell membranes. Our previous data have shown that 2,3-Butanedione Monoxime (BDM) could inhibit the calcium current by dephosphorylation of the channel. In this study, the effect of BDM on the potassium channels were investigated with the whole-cell recording method in single myocytes enzymatically isolated from the left ventricle of 3-4 months old rats. Superfusion of myocytes with BDM elicited a dose dependent decrease of the outward transient potassium current. BDM with concentrations of 5, 20 and 50 mM reduced the maximal peak potassium current by 7.3 …

Red And Green Make Yellow: An Interactive Multimedia Tutorial Designed To Teach The Basic Concepts Of Additive And Subtractive Color, Suzanne Grinnan

Theses

The division between designers and printers is becoming increasingly blurred as the capabilities of the desktop environment improve. Electronic imaging is one area where this disintegration is rapidly occurring. Abilities that were formerly the domain of the color separator, image assembler, and printer, such as scanning, color correction, and film separation, are available through many popular software programs. Unfortunately, the education required to allow the proper application of these software options is not as accessible as the tools themselves. Both printers and graphic designers will have to educate themselves about the emerging and changing technologies of the other. Eventually a …

Framemaker(Tm) Software Applications Handbook, Philip Dixon

Theses

The purpose of this study is to develop a reference source that integrates information on incorporating text, graphics, and images into a page layout program. Historically, the technical writer was only responsible for the creation of text and utilized the services of a graphic artist for the creation of images. This process is time consuming and introduces errors into the publishing process. Currently, technical publishers are becoming responsible for the complete documents graphics, text, and images using word processing, design/illustration, CAD/CAM, and photo/image manipulation programs. Thus, the user must have training in the correct use of the four programs listed …

An Analysis Of How Altering Exposure Effects Color Differences In Critical Color Areas On Electrophotographic Off-Press Proofs, Jill Houghton Mudge

Theses

The purpose of this paper was to quantitatively analyze off-press color proofing methods for advertising material appearing in halftone publication gravure printing. This type of proofing has been an area of debate for the publications industry, especially in reference to the print quality of advertising material. The correlation between dot gain characteristics and the resulting color differences of off-press color proofing methods has been the center of greatest controversy. This paper has tested to determine if a correlation exists between dot gain characteristics and the resulting colorimetric-matching ability for color proofing methods used in halftone publication gravure. The variable dot-gain …

A Study Of Color Image Data Compression, Vassilis Koutsogiannis

Theses

The space which black and white or color images require to be stored introduces one of the biggest problems in the field of Graphic Arts. A solution to this problem is offered through the use of software programs that compress the data of a scanned image. Compressing images without any consideration can create other problems. These problems arise because each image has a different structure . It is possible to classify images into three main categories using as a criterion the frequencies the images contain. The first category includes images that contain high frequencies -a lot of detail and very …

Bispectral Reconstruction Of Speckle-Degraded Images, Song Jin

Theses

The bispectrum of a signal has useful properties such as being zero for a Gaussian random process, retaining both phase and magnitude information of the Fourier transform of a signal, and being insensitive to linear motion. It has found applications in a wide variety of fields. The use of these properties for reducing speckle in coherent imaging systems was investigated. It was found that the bispectrum could be used to restore speckle-degraded images. Coherent speckle noise is modeled as a multiplicative noise process. By using a logarithmic transformation, this speckle noise is converted to a signal independent, additive process which …

An introduction to photographic exposure calculations is also reviewed. The shutter system is broken down into three models for analysis: a magnetic model, a mechanical model, and a photometric model. The equations of motion are derived, based on the electromagnetic field calculations. The governing equations are analyzed using the Advanced Continuous Simulation Language (ACSL) software, and the …

A Study Investigating The Impact Women Have On The Bindery, Melanie Lee

Theses

The evolution of women from working mainly in the household to the work place began out of an economic need on the United States' part. With the westward expansion of the country and the Civil War during the nineteenth century, there was a shortage of male labor and women were hired as unskilled workers, at first, to keep the economic growth pace of the country in line with its physical expansion. Women became the predominant labor force in industries such as tobacco, textiles and bookbinding. As book manufacturing grew to provide books for the mass population, women were the manual …

The Design And Construction Of A Hang Glider Flight Simulator, Kim L. Sherman

Theses

Hang gliding is probably the closest a person can come to experiencing bird-like flight. Unfortunately, the precise skills needed to fly a hang glider are difficult to teach through demonstration or verbal instruction. Consequently, many people's first few flights are awkward and sometimes dangerous. A hang gliding student's first flight is a solo flight, so control errors are understandable. However, every effort must be made to minimize these errors.

Validation Of Dirsig, An Infrared Synthetic Scene Generation Model, Donna D. Rankin

Theses

A validation and sensitivity study was performed in which the accuracy of an infrared synthetic image generation model (DIRSIG) was examined. The majority of the error in the model is derived from two major programs: a temperature predictor and a radiative transfer model. A thermodynamic model computes kinetic temperatures of objects in a computer generated three-dimensional scene. These temperatures, atmospheric data, and sensor parameters are used as input to a ray_tracer which models the propagation of radiation in a source-target-sensor path within this scene. The output is a simulated infrared image which a sensor with the given input parameters would …

Achromatic Perception In Color Image Displays, Mark E. Gorzynski

Theses

The perception of achromatic colors is an important aspect of CRT color appearance. Achromatic colors are important for practical reasons such as image color balance and as fundamental components of chromatic adaptation and color constancy research. Data on achromatic colors is absolutely essential for applying CIE colorimetry to CRT-hardcopy matching. For example, the CIELAB formulas require the specification of the tristimulus values of white. Unfortunately, psychophysical data on the perception of achromatic colors, including white, in CRT-hardcopy matching situations is not readily available in the literature. The purpose of this research was to investigate factors that affect the perception of …

The Rit Ieee-488 Buffer Design, John Connor

Theses

This document describes the design of an NMOS ASIC used to control an RIT IEEE-488 Buffer previously designed by the author. Past designs used discrete components to implement an asynchronous controller and a synchronous, one-hot controller. The present design utilizes a multiple controller architecture incorporated within the ASIC. The ASIC is used to control bus protocol, bus transceivers, and memory. At power-up, the buffer configures itself as an active listener on the bus and waits for a talker to initiate communication. The buffer accepts a data file (a plot file for example) from the talker, then takes control of the …

A Comparison Between The Staggered Position One-Angle Screening Method And The Multi-Angle Screening Method In Terms Of Misregistration When Printing Process Color On Newsprint, Ivan M. Latanision

Theses

The multi-angle screening configuration is by far the most widely used screening configuration for process color printing, but there are alternative screening configurations which may be preferable in certain situations. Color separations made using the Staggered Position One-Angle screening configuration are reported to provide printed reproductions on newsprint which appear sharper, offer improved color reproduction, produce smoother color reproduction, and preserve color better in the shadows. The staggered position technique can be generated with high-end scanners and prepress equipment, as well as with desktop publishing workstations using the "Flamenco" screening algorithm. However, the staggered position method may be subject to …

Dynamic Machine Scheduling, Expansion, And Control Of A Generic Workcell, Peter A. Murray

Theses

Factory automation has come a long way since the invention of the automatic flour mill. A workcell is a group of machines (robots) working together to produce a product. In the past workcells have been hard wired using methods such as Programmable Logic Controllers (PLCs). To change a part of this system would require reprogramming the entire system.

The Generic Work Cell (GWC) is a dynamic architecture which allows a workcell to be modified on the fly. The architecture enables the generation of new cells with minimal effort, and the modification of the system without reprogramming the entire system. The …
