Modeling Of The Radiometric Characteristics Of A Simulated Fluorescent Imager, Alexander Granica

Theses

The purpose of this study was to determine whether changes in stimulated plant fluorescence could be detected by a remote sensing system. By measuring the changes in fluorescent signal the health status of vegetation can be determined. The plant condition can be assessed by viewing the ratio 690 nm/ 730 nm from the fluorescent spectra at the leaf level. The question is whether the change in fluorescent spectra (change in the ratio) can be seen at a remote location. In order to address this question a theoretical scenario was developed and the expected signal at a remote location was determined …

Visual Determination Of Hue Suprathreshold Tolerances, Yue Qiao

Theses

A visual experiment was performed to generate suprathreshold tolerances sampling the direction of CIELAB hue, thereby extending the RIT-Dupont dataset. Thirty nine color centers including three complete hue circles at different lightness or chroma levels and three CIE recommended colors (red, green, blue) were evaluated for hue discrimination. Forty five observers participated in the pass/fail experiments. A total of 32,226 visual observations were made. The statistical method, logit analysis with 3-dimensional normit function, was used to determine the hue discrimination suprathreshold for each color center. The results indicated that the hue discrimination suprathresholds of observers varied with hue angle. The …

Museum Of Formosan Aborigines, Yuan-Feng Cheng

Theses

In the beginning, the purpose of this thesis was to explore the feasibility of creating a computer-based visual museum. I wanted to experiment with 3-D interactivity, such as how to set up the cursor movement in a 3-D world and how to use 3-D animation in interactive multimedia. I wanted to use Native Americans as the subject of this 3-D museum project. After I sent my thesis proposal to our department, I found my classmate's project was about Native Americans also. Therefore, I decided on another topic. In July 1995, 1 went back to Taiwan to visit my friends. I …

A Multipurpose Mri Phantom Based On A Reverse Micelle Solution, Jo Roe

Theses

Magnetic resonance imaging (MRI) phantoms are anthroprogenic objects used for system performance testing of an MR imager. Current phantoms used today contain aqueous solutions of paramagnetic salts. When imaged, these phantoms produce a standing wave artifact. The presence of this artifact make it difficult to distinguish between inhomogeneities in the B] transmit and receive field of an imaging coil and the imaging phantom. This thesis describes a reverse micelle (RM) solution and its applicability for use in an MR imaging phantom. The RM solution consists of three components: H20, which is surrounded by the surfactant, AOT, to form a droplet, …

However the prepress process has undergone radical changes over the past decade due to the introduction of desk top publishing and desktop prepress. Alongside of the desktop publishing revo lution has come a multitude of new digital proofing technologies for use in this ever changing environment. Technologies including, but not limited to, liquid inkjet, dye sublimation, continuous inkjet, color laser, and thermal wax transfer printers have provided an entire range of color accuracy and price suitability to many of their users. However one …

Optimization Of Template Selection For Signal Detection Systems With Additive Internal Noise, Shan Xue

Theses

According to studies done by M. I. Trifonov, the form of the optimal detection template for an observer model with additive internal noise depends not only on the signal to be detected, but also on the internal-external noise ratio. The optimal detection template described by Trifonov's theory indeed exhibited superior performance over the conventional "matched filter" template, but the mathematical procedure Trifonov proposed for proving his theory was insufficient. During the course of this thesis project, an extensive research was carried out to study Trifonov's theory and its implications. As a result of this research, a new mathematical technique was …

Dirsig Digital Imaging And Remote Sensing Imaging Generation Model: Infrared Airborne Validation & Input Parameter Analysis, Todd Kraska

Theses

The civilian and military need for high resolution infrared imagery has dramatically increased in recent times. Regardless of the user or the need, infrared imagery can provide unique information that is not available in the visible region of the electromagnetic spectrum. Just as the need for real infrared imagery has increased, so has the need for computer generated infrared imagery, also known as synthetic imagery. Synthetic imagery is created by mathematically modeling the "real world" and the imaging chain, encompassing everything from the target to the sensor characteristics. The amount of faith that can be placed in a synthetic image …

Automatic Train Control Using Neuro-Fuzzy Modeling And Optimal Control Techniques, Michael Natkin

Theses

In rapid transit applications, it is often necessary to optimize the ride of the train for certain parameters based upon time of day, occupant density, and system-wide scheduling. Trade-offs have to be made between energy conservation, time minimization, and ride comfort. Typically the dynamics of the train are not well known (or not initially known at all), change over time, and are non-linear. In the past, a transit control engineer would typically use P-I control but could spend days or weeks on-site adjusting the P-I constants to obtain a ride that felt good and met the design constraints. This process …

A Directorial Experience: Noises Off, Jennifer Lynn Forrest

Theses

Over the years I have been exposed to hundreds of shows, some excellent and other's not quite as good. Few shows that I have read, seen, or been involved with seem to have the appeal to both audiences and theatre groups as that of Michael Frayn's modem farce Noises Off. There are several strong reasons for its appeal.

One of the primary reasons for the play's popularity is that it is a reaction against modem theatre's tendency toward preaching at the audience. Contemporary plays tend to teach morality; and while modern playwrights do occasionally use comedy as a vehicle …

Color-Appearance Modeling For Cross-Media Image Reproduction, Karen Braun

Theses

Five color-appearance transforms were tested under a variety of conditions to determine which is best for producing CRT reproductions of original printed images. The transforms included: von Kries chromatic adaptation, CIELAB color space, RLAB color appearance model, Hunt's color appearance model, and Nayatani's color appearance model. It was found that RLAB produced the best matches for changes in white point, luminance level, and background changes, but did not accurately predict the effect of surround. The ability of CIELAB color space was equal to that of RLAB in many cases, and performed better for changes in surround. Expert observers generated CRT …

Validation Of The Use Of Sharc Hydrocode To Predict Explosion Effects In Vented Chambers, Gary Bush

Theses

Computational Fluid Dynamics (CFD) models were created and analyzed using the commercially available hydrocode SHARC to determine if SHARC can accurately predict the behavior of explosions in enclosed vented chambers. Axisymmetric two-dimensional models were generated using the same physical parameters used in similar model tests performed by the US Army. Three different chamber/vent configurations were investigated with three charge sizes per configuration in order to compare the SHARC results to the data obtained from the model tests. The time of arrival of shocks and the peak over-pressure were compared. The calculations were then analyzed using several graphical tools currently available. …

Modeling The Mtf And Noise Characteristics Of An Image Chain For A Synthetic Image Generation System, Frank Tantalo

Theses

This is an approach for modeling sensor degradation effects using an image chain applied to a synthetic radiance image. The sensor effects are applied in the frequency domain by cascading modulation transfer functions (MTF) and phase transfer functions (PTF) from the different stages in the acquisition portion of the image chain. The sensor simulation is intended to not only degrade an image to make it look real, but to do so in a manner that conserves the image's radiometry. Some common transfer functions steps include; effects from the atmosphere, optical diffraction, detector size, and scanning motion. The chain is modeled …

Emotional Content In Gestural Process And Form, Robin Yates

Theses

The sculptures focus on the influences emotional content has in my work, and address processes and forms that feelings inspire. One of the main influences in my art is the spectacular Niagara Gorge; the eroded riverbed, the water, and the cliffs. In the documentation of my thesis investigation, I emphasize ritual of process. I realize that in preparing myself to work I set an aesthetic mode important to the development of form. I describe specifics concerning my process so it seems to the reader that they are directly involved while I am working. In reflection, I now realize that visual …

Significance That A Learning Tool To Enhance The Understanding Of The Principles Of Printing Has An Effect On The Productivity Of Color Laser Copier/Printer Operators, Annmarie Scamacca

Theses

As the complexity of laser color copiers/printers evolve in this fast-paced, technological, quick-print industry, the amount of printing knowledge that is required to operate these devices is considerably declining. Advancements in the color laser printing arena are expanding every day. With the introduction of more precocious color printing units coupled with an infinite number of features, a broader market of users becomes available. Increasingly, non-traditional printing users are becoming involved with color copier/printer devices. There are several reasons why this infusion is taking place. Foremost, the technology now exists to convert "ordinary" black pages into full color documents. Secondly, there …

I will be exploring a variety of glazed, painted, and textured surfaces which will allude to the passage of time. I will give my audience just enough …

Recursive Analysis And Estimation For The Discrete Boolean Random Set Model, John Handley

Theses

Random sets provide a powerful class of models for images containing randomly placed objects of random shapes and orientation. Those pixels within the foreground are members of a random set realization. The discrete Boolean model is the simplest general random set model in which a Bernoulli point process (called a germ process) is coupled with an independent shape or grain process. A typical realization consists of many overlapping shapes. Estimation in these models is difficult owing to the fact that many outcomes of the process obscure other outcomes. The directional one-dimensional (ID) model, in which random- length line segments emanate …
