S.57392, Christine Lo

Theses

The idea of creating and writing a thesis loomed before me as an awesome task I would never be able to bring to fruition. However, the time came when I had to sit down and seriously ask myself how I would like to spend the remainder of my time here at RIT. Regretfully, I cannot say that there was a burning passion within me. I began to approach the thesis topic and asked myself, "What is out there that has yet to be fully explored?" Looking through several articles and speaking with a diverse group of people, I became involved …

From The Screen Through The Screen, Marianne O'Loughlin

Theses

This thesis project's aim is to transfer the early or beginning read er's interest and focus from the video screen; i.e.: television or Nintendo, to the printed text of the book through interaction with the computer by reinforcing the narrated story with on-screen text. Much like read-along audio tapes, the premise of this thesis is to combine pictures, words and sound into a computerized support for a story. To create interest for the proposed age group, the criteria used will be based on an entertaining tale, quest, or game, rich in language and illustration, intermixed with humor. The goal is …

Uaguzi, Christopher Erin Walsh

Theses

I came to RIT, for a MFA in Computer Animation, with one aim in mind: to learn 3D animation. The most difficult part about my animation theses was finding a project that would challenge all that! had learned up to this point. I didn't want to just fly the camera around objects, as I'd seen in previous theses' and three dimensional animations. That was the easy way out! I set my goals high. I wanted to see if I could bring characters to life in 3D. I wanted to take traditional two dimensional character animation techniques and apply the movement …

Model Parameter Identification Of The Oscillatory Potential In The Electroretinogram, Sung Hoon Jang

Theses

A mathematical model of the oscillatory potential which may be a useful clinical tool to diagnose the progression of diabetic retinopathy. The model has been investigated by compressing from oscillatory potential into three parameters which contain most of the information for the oscillatory potential data.

About thirty subjects including both normal and diabetic subjects were investigated in this study. Comparing normal and diabetic subjects, we found amplitude parameter was most important factor to classify subjects by normal and diabetic.

Since modeling of the oscillatory potential and the estimation of the model parameters were our final goal, we haven't proposed to …

Optimization Of Flow In The Collecting Duct During The Concentrating Mode And The Diluting Mode In A Nephron Population Of Two Different Length With The Renin Angiotensin System And Adh Mechanism, Sivakumar Subramanian

Theses

Our present study is to find out how the short and long nephrons are interacting in the human kidney to adjust the flow in the collecting duct to have the maximum flow during the diluting mode and minimum flow during the concentrating mode. The best lengths for the short nephron and long nephron are calculated during the concentrating mode and the diluting mode by using the Newton-Raphson method. If one wants the kidney to perform only the above mentioned functions, a design criteria for an artificial kidney has been proposed. These studies have provided qualitative information regarding the concentrating mechanism …

The Nature Of Beads, Michele D. Miller

Theses

The purpose of this thesis is to explore the various qualities of nature through the concept of the bead. A series of beads has been created whose aesthetic elements enhance the essence of nature and the spirit of the individual. With these pieces I wanted to express my sensitivity and feelings about nature relating to seasons of the year and personal memories. It is my hope that this body of work will heighten an awareness of nature and arouse thought and curiosity about beads.

Cullet, Charles Sorrels

Theses

This paper discusses a series of five sculptures that are now five and one-half years old. Today these sculptures are scattered and in some cases gone, but the goals and the decisions which shaped their creation in 1986 and 1987 are still fresh in my memory. They were important experiments for me, and I carry them with me today. I would not claim these sculptures defined me as the artist I am now, but they do define me as the artist I was then. And to that extent, my understanding of myself is enriched by this thesis work. In 1986 …

Techniques Of Petri Net Reduction, Sreeranga Kalavapalli

Theses

Petri Nets have the capability to analyze large and complex concurrent systems. However, there is one constraint. The number of reachability states of the concurrent systems outweighs the capability of Petri Nets. Previous Petri Net reduction techniques focussed on reducing a subnet to a single transition and hence not powerful enough to reduce a Petri Net. This paper presents six reduction rules and discusses their drawbacks. A new reduction technique called Knitting Technique to delete paths of a Petri Net while retaining all the properties of the original net is presented. Further Structural matrix which facilitates reduction is presented.

Blur Identification And Restoration Of Images Of Coronary Microvessel, Kuen Tak Wong

Theses

The objective of this research was to identify the blur characteristics of the blurred images of the rat coronary microvessel, and the information of the blur characteristics was used to restore the blurred images. The blur characteristics were analyzed by using the image power cepstrum. The Wiener filter was implemented to restore the images. There were two types of point spread functions proposed and studied for the restoration. They were: defocus blur PSF and motion blur PSF. The images were transferred from HP A900 system to an AVS workstation. The images were processed and manipulated by the AVS, and showed …

Classification Of Patterns In Eeg Recordings : A Comparison Of Back-Propagation Networks Vs. Predictive Autoencoder Networks, Brian Armieri

Theses

Recent research exploring the use of neural networks for electro-encephalogram (EEG) pattern classification has found that a three-layer back-propagation network could be successfully trained to identify high voltage spike-and-wave spindle (HVS) patterns caused by epileptic seizures (Jando et. al., in press). However, there is no reason to predict that back-propagation is the best possible network architecture for EEG classification. A back-propagation neural network and a predictive autoencoder neural network were compared to determine which network was better at correct classifying both HVS and non-HVS patterns.

Both networks were able to classify 88%-89% of all patterns using a limited set of …

Laboratory Health And Safety Compliance Guide For Private Colleges And Universities, Gina Marie Ochs

Academic laboratories are presented with the unique challenge of ensuring the health and safety of all people involved in daily activities. The Occupational Safety and Health Administration (OSHA) recently enacted the regulation 29 CFR 1910.1450, "Occupational Exposure to Hazardous Chemicals in Laboratories," which applies to all private employers (including colleges and universities). In this work, a guide is developed to assist private colleges and universities comply with applicable governmental regulations and to ensure the health and safety of all individuals involved with laboratory activities.

Academic laboratories warrant special consideration because of the nature of experimentation (variation in research and classroom …

Recursive Soft Morphological Filters, Padmaja Puttagunta

Theses

Mathematical morphology which is based on set-theoretic concept, extracts object features by choosing a suitable structuring shape as a probe. Morphological filters are set operations that transform an image into a quantitative description of its geometrical structure: Appropriately used, they can eliminate noises or irrelevancies while preserv¬ing the details of the original image. The applications of morphological filters in image processing and analysis are numerous, which include shape recognition, industrial parts inspection, nonlinear filtering, and biomedical image processing.

Soft morphological filters are used for smoothing signals with the advantage of being less sensitive to additive noises and to small variations …

Computer Simulation Of Intracranial Hemodynamics During The Induction Phase Of Anesthesia, Gopinath P. Sundaram

Theses

The induction of general anesthesia is associated with severe hemodynamic compromises which, in turn, may cause acute elevation of intracranial pressure (ICP). Quantitative assessment of cerebrovascular responses arising from multiple mechanical and pharmacological interventions occurring in a short time interval require a large number of human studies which are difficult to perform. The purpose of this project is to evaluate the effect of various stimuli on the intracranial hemodynamics during induction using a mathematical model of cerebrovascular circulation.

A five compartmental model of the cerebrovascular system is used for our simulation. Autoregulation is modeled by adjusting arterial-arteriolar resistance in order …

Mixed Culture Biodegradation Of Pentachlorophenol, Hexachlorobenzene, And Tetrachloromethane Under Anaerobic Conditions, Jesse Zahn

Theses

Three chlorinated compounds, namely, Pentachlorophenol(PCP), Hexachlorobenzene (HCB), and Carbon tetrachloride were biodegraded under anaerobic conditions using a (CCl₄)mixed culture obtained from an anaerobic sewage sludge digestor in Linden, NJ.

Three sets of cultures capable of degrading each of the target compounds were established. Primary Enrichment Cultures (PECs) from the anaerobic sludge were exposed to each one of the target compounds. The cultures were able to degrade each target compound as follows: HCB, 0 to 1.2 ppm; PCP from 0 to 3-4 PPM; CCl₄, 0.5 to 15.5 PPM

One culture from each PEC group (CCl₄, …

Simulation Of Manufacturing Cell Using Hoops Graphic Software And Siman Simulation Language, Parikh Vipul

3d Alchemy: A Guide To 3d Realistic Computer Graphics, Ching-Pei B. Han

Theses

Last year, many films and commercials took advantage of computer technology to create astonishing 3D animations. Examples such as the Listerine commercial series, the NBA logo on TV, and the Chip & Pepper TV cartoon, featured unique and vibrant computer images. Among the various animations, some were made by high end computer systems, but some simply by personal computers. Small, fast, and more capable personal computers are now performing professional-level video production roles and, in fact, they are a staple of many feature film productions and broadcast television facilities.

The purpose of my thesis is to present Virtual Reality as a tool in aiding Education. I used the Macintosh computer as the driving base of my project, and configured inexpensive commercially available computer peripherals as input devices. I investigated the effectiveness with which virtual worlds can present information, as well as studied the use of low cost software, input devices and drivers currently avail able on the Macintosh Computer. In addition, this thesis describes the strength, weaknesses and concerns involving the use of Virtual Reality in learning and the limitations of the current technology.

Global Housekeepers, Mary Arp

Theses

It all began with a small, clipped image from a 1940' s Good Housekeeping magazine. There she was: a two inch tall housewife, prim in both her apron and hair style. Her arms were extended: one for balance and one with a cloth for cleaning. I took this "cleaning woman" image to Kinko ' s , the 24 -hour copy center where I spend too much time. There, I made successive photocopies and enlargements until I had a stack of grainy, obviously mechanically reproduced "drawings". Back in the studio, with a 4B charcoal pencil and paper, I vigorously drew backgrounds …
