Time-Frequency Distribution Analysis Of Heart Rate And Blood Velocity Variabilities In Stage 24/34 Chick Embryos, Andrew Bonacci
Time-Frequency Distribution Analysis Of Heart Rate And Blood Velocity Variabilities In Stage 24/34 Chick Embryos, Andrew Bonacci
Theses
Time-frequency distribution (TFD) analysis is a relatively new process for decomposing a complex signal to understand its spectral content Traditional signal spectral analysis examines both temporal and spectral contents distinctly. This method of analysis is suitable for signals where the spectral content is stationary and time-invariant. However, many naturally occurring signals are not only multicomponent, but are also highly time-variable, such as speech, heart rate variability, and other biological signals. Typically, the Fourier transform exposes sinusoidal frequencies present in a signal. It cannot, however, tell when these frequencies existed temporally. This is where timefrequency analysis excels over traditional spectral processing …

Hydroboration Of Alkenes Catalyzed By Rhodium Compounds, Lu Yang
Theses
Hydroboration of 1-octene in the presence of RhCl3-Aliquat 336 catalyst for different reaction times ( 24, 10, 5 and 2 hours ), results in 2-octanol as the major product , which means that Markovnikov addition is the major process . Different solvents and temperatures caused some changes of product ratio of 2-octanol to 1- octanol. The same catalyst system has been found to hydroborate styrene in an anti- Markovnikov fashion.

Removal Of Volatile Organic Compounds From Contaminated Groundwater By Pervaporation, Sukla Chandra
Removal Of Volatile Organic Compounds From Contaminated Groundwater By Pervaporation, Sukla Chandra
Theses
Effective removal of non-aqueous phase liquid pools in groundwater and volatile organic compounds (VOCs) from contaminated soils can be achieved by surfactant flushing. This surfactant-rich ground water contains VOCs like trichloroethylene (TCE), dichloroethylene (DCE), etc. Membrane pervaporation technique is employed here to remove TCE from these micellar systems where a very high percentage of the VOC is trapped inside the micellar core. The micellar solution flows through the bore of microporous hydrophobic hollow fibers wherein the micelles break down and release the surfactants and the TCE. The TCE is then removed through the pores and a nonporous thin silicone skin …

Development Of A Gel Content Analysis Protocol For Ultra High Molecular Weight Polyethylene, Max Harold Jeanty
Theses
A modified procedure based upon ASTM (D 2765 - 90) to determine the gel content of crosslinked polyethylene plastics was developed. The new procedure was applied to ram extruded Ultra High Molecular Weight (UHMWPE) implant components processed under different manufacturing conditions. This new evaluation tool provides consistent results with greater accuracy and consistency compared to the American Society for the Testing of Materials (ASTM) method. Using the same tool, several relationships between the UHMWPE processing conditions and gel content were established. The amount of gel content is related to the crosslinked material. It has been shown that the more crosslinking …
Press Performance Of Frequency Modulated Screen Printing On Newsprint, Li-Yi Ma
Press Performance Of Frequency Modulated Screen Printing On Newsprint, Li-Yi Ma
Theses
Frequency Modulated (FM) screening has been praised for its apparent resolution advantage over conventional halftone screening. Studies showed FM screening can be processed with the existing technology, and it does bring about a visible improvement in image quality on newsprint. This study focused on the press performance of the FM halftone printing on newsprint. The fineness of conventional halftone screens can be described by indicating the screen rulings (lines per inch or lpi), and the fineness of FM screens is measured by the size of the micro dots ([micron] or 10~6m). It is difficult to equate the microdot size in …

Lei Rimana "She Stays", Keith Watson
Theses
My concept is to re-evaluate and advance personal communication aids, generally, but not entirely, in the form of greeting cards, to a new level of interest and signification. The goal is to eliminate the passive viewer, and have the individual actively participate in the presentation. The computer-based, interactive media project is designed around three-dimensional sculptures, which serve as "narrators," and put back the one-to-one interaction that is so often missing in non-verbal greetings. In combining technology with more traditional storytelling techniques, it will develop and express a personal message that will help reinforce the intent of the message by becoming …

Bubble Growth Rate And Heat Transfer Suppression In The Flow Boiling Of Binary Mixtures, Taavo Raykoff
Bubble Growth Rate And Heat Transfer Suppression In The Flow Boiling Of Binary Mixtures, Taavo Raykoff
Theses
An investigation is undertaken into the nature of the bubble growth rate and heat transfer suppression in the flow boiling of binary mixtures. From an examination of the well established pool boiling theory available in the literature and a consideration of factors uniquely present in flow boiling situations, it is determined that the present pool boiling theories are roughly applicable for a finite initial interval of the bubble growth cycle during flow boiling. Furthermore, it is hypothesized that the suppression of the increase in heat transfer coefficient in binary fluids which occurs after the onset of nucleate boiling is related …

A Petri Net Design, Simulation, And Verification Tool, Richard Brink
Theses
Increasing desire for thorough simulation and analysis of engineered products is quickly replacing the prototype and test design model. Petri nets are important instruments for modeling concurrent, distributed, asynchronous, parallel, deterministic, and non-deterministic systems. This tool provides designers with the ability to easily specify a Petri net design with an easy to use user interface, then simulate and analyze the Petri net to determine essential design properties using the reachability tree technique. The tool will construct a reachability tree, then analyze the tree for properties of safeness, boundedness, liveness, and conservativeness.
Modeling Ventricular-Vascular Coupling In The Developing Embryo, Michael Bauman
Modeling Ventricular-Vascular Coupling In The Developing Embryo, Michael Bauman
Theses
Congenital cardiovascular malformations are one of the major contributors to infant mortality in the United States today. Defects in the cardiovascular system are evident at very early stages in the developing embryo, yet there exists no substantial diagnostic tool(s) for recognizing defects at these early stages. Cardiac morphogensis occurs throughout the pre-innervated period of embryonic development. It is speculated that the flow of blood during the early embryonic stages plays an important role in the development of the cardiovascular system. Blood flow is a possible mechanism for communication between the heart and vasculature, contributing to cardiac development. The objective of …

The Boat As Sculptural Metaphor, Place Scott
Theses
This thesis was undertaken to explore the possibilities of utilizing the boat as a unique form for my own work in the realm of ceramic sculpture. I dealt with the boat as a metaphor to depict personal fantasies, daydreams and past encounters. In these pieces I depict the sense of freedom I feel from skimming across the surface of water. Some appear as though they are in rapids of a river. Another is a depiction of being in the middle of a big body of water and feeling rather small.

The Effect Of Cylindrical Obstructions On The Fluid Flow In Narrow Rectangular Channels, Gary Compagna
The Effect Of Cylindrical Obstructions On The Fluid Flow In Narrow Rectangular Channels, Gary Compagna
Theses
This thesis presents a computational fluid flow analysis in narrow rectangular channels, with regular spaced cylindrical disks acting as obstructions to fluid flow. The problem geometry is based on an approximation of the configuration used in a PCR detection chamber. Polymerase chain reaction (PCR) is a method of DNA analysis that depends on the flow uniformity within the detection channel. The nominal channel is a narrow channel with a maximum gap height of 0.13 mm and a maximum width of 5.0 mm. The fluid flow rate and channel size result in a Reynolds number less than 5. The effect of …
