Drug Use And Pregnancy, Kimberly Klapmust

Theses

Human development is a remarkably complex process whereby the union of two small cells can after a period of time give rise to a new human being, complete with vital organs, bones, muscles, nerves, blood vessels, and much more. Considering the intricacy of the developmental process, it is indeed miraculous that most babies are born healthy. Some children, however, are born with abnormalities. Environmental agents, such as drugs, are responsible for some of these abnormalities. Unfortunately, social and therapeutic drugs are widely used among pregnant women. Many commonly used drugs are known to disrupt the normal developmental process and cause …

Multiple Document Detection With Ultrasonics, Daniel Phinney

Theses

The purpose of this thesis was to develop a method to detect the occurrence of more than one document being drawn into an automatic document feeder such as is used on photocopiers and document scanners. It was desired that the method developed made no physical contact with these documents, worked with all common document materials and thicknesses. The method actually developed monitors the amplitude and phase changes in ultrasound passed through these documents. By using both the amplitude and phase of the ultrasound, a material and thickness independent method, non contact method was successfully developed.

An Investigation Of Polyethylene Bearing Wear Of New Jersey Lcs Knee On Cobalt Chromium And Titanium Nitride Types, Lei Wang

Theses

The total knee replacement systems (TKRS) are used for the treatment of osteoarthritis and rheumatoid arthritis. Excessive wear can substantially shorten their life span.

Two tests were performed to examine the wear characteristics of tibial bearings used in TKRS. Each test consisted of six sets of Anterior/Posterior Glide Tibial Bearings each with a conical control arm. The tibial bearings were all made by UHMWPE. Three of these bearings were mounted onto a Co-Cr alloy tibial platform and Co-Cr alloy LCS® femoral component. Another three sets of bearings were mounted onto a TiN tibial platform and TiN LCS® femoral component. They …

Fingerprint Recognition Through Circular Sampling, David Chang

Theses

The uniqueness of the human fingerprint is considered to be one of the most reliable characteristics for personal identification. Considering that we leave them on nearly all of the surfaces we touch, they become valuable to those in law enforcement for identifying perpetrators of a crime. However, the matching of a single fingerprint with the millions that have been cataloged proves to be a difficult task. This study presents an alternate method to fingerprint recognition by way of a spatial re-sampling of the pattern through concentric circles. With this approach, the concentric circular samples have rotation invariant features while a …

The Relationship Between Personality Type And Career Pathway Choices Among Ninth And Tenth Grade Students, Margaret Mcilroy Goodin

Students were divided into six groups on the basis of their previously chosen career pathway. as prescribed by the Missouri Model Guidance Program. using the Career Pathways Interest Inventory (CPIJ). The purpose of this study was to determine whether there was a significant relationship between personality type and career pathway choice among adolescent students. The two variables were compared using a chi-square statistical analysis. Results indicated that a significant relationship between personality type and career …

Assessing Career Value Of Hospitality Management Curriculum From Program Alumni, James Reid

Theses

The purpose of this study was to investigate the assessment of hospitality management baccalaureate program alumni from New York Technical College (NYCTC) as being a valuable resource to the Hospitality Management curriculum assessment effort . Through the development of an alumni questionnaire, participants in this study were asked to rate individual courses of their curriculum (both core and elective) by the degree of value each course had been in terms of usefulness to their career development and/or relevance to meeting the demands of their current positions. Although the questionnaire response rate was less than desirable, it is stressed that survey …
