Mobility As An At-Risk Factor For Student Loneliness, Chad T. Towers

Theses

Student alienation is a complex and difficult experience for adolescents. One factor that counteracts alienation is peer acceptance. Often the changing of schools makes it difficult for adolescents to be accepted by their peers. This lack of peer acceptance often brings on feelings of loneliness. This study sought to determine if changing schools had a significant effect on student loneliness. Twenty mobile, or new, middle school students were compared with 26 stable students, who had been at the middle school since the beginning of their sixth grade year, to see if changing schools had a significant effect on student loneliness. …

Development And Evaluation Of An Intrinsic Gettering Process For Fabrication Of Integrated Circuits, James Ii Will

Theses

An internal gettering process to collect and trap potentially harmful defects in the bulk of the silicon wafer, away from the surface where the integrated circuits are fabricated, has been developed in this work. This gettering process was then incorporated into the standard metal gate PMOS process utilized at RIT. Capacitors and diodes were electrically characterized to compare wafers that were gettered versus wafers that were not gettered.

Solid Phase Organic Synthesis: Investigation Of Resins And Linkers For Phenols, Laurie Seifert

Theses

A loading and cleaving study was performed on solid phase to determine the optimal linkers and conditions for phenols, a key functional group in photographic couplers. Fourteen different commercially available resins were analyzed. Of these, ArgoGel Wang CI was determined the best for loading and cleaving the model phenol coupler. Yields of 95% for both loading and cleaving were achieved as determined by MAS Nanoprobe NMR and HPLC respectively. A few others gave great loading (90- 100%) such as Merrifield, Brominated Wang, Bromo PPOA, and TentaGel COOH, however poor cleavage ability rendered these resins insufficient for phenols.

Product Clustering For Focused Factories And Cellular Manufacturing, Judith Batista

Theses

In the past, clustering analysis techniques have been broadly utilized to segment markets. Recent studies (Berry et al. 1991) have used market-based clustering to examine manufacturing operations required to be competitive in different market segments. These authors proposed a methodology to categorize a set of products based on their similarity across a set of key variables, such as order-winning criteria, time considerations and volume levels. Their method incorporated the Agglomerative Hierarchy with k-Means Refinement Model to identify groups of similar products to be manufactured in a focused-factory. While many other multivariate clustering methods exist in the literature, the application of …

The Relationship Between Homophopia And Fear-Of-Intimacy In Heterosexual College Students, Bonnie S. Wilke

Theses

This thesis explores the relationship between homophobia and fear-of-intimacy in heterosexual college students, with a focus on gender differences. The study builds upon existing research suggesting that men often display higher levels of homophobia and fear-of-intimacy, potentially due to gender role socialization, cultural expectations, and psychosocial development patterns. Using Erikson's theory of psychosocial development and various social and psychological frameworks, the author hypothesizes that homophobia may act as a barrier to intimacy, especially in men.

A sample of 65 heterosexual undergraduate and graduate students (23 males and 43 females) from a Midwestern private university participated in the study. Participants completed …

A Vhdl Design For Hardware Assistance Of Fractal Image Compression, Andrew Erickson

Theses

Fractal image compression schemes have several unusual and useful attributes, including resolution independence, high compression ratios, good image quality, and rapid decompression. Despite this, one major difficulty has prevented their widespread adoption: the extremely high computational complexity of compression. Fractal image compression algorithms represent an image as a series of contractive transformations, each of which maps a large domain block to a smaller range block. Given only this set of transformations, it is possible to reconstruct an approximation of the original image by iteratively applying the transformations to an arbitrary image. Compression consists of partitioning the image into range blocks …

A Theoretical Model Showing The Effects Of The Fuel Induced Gamma Effect, Bryan Bordeleau

Theses

The Fuel Induced Gamma Effect uses pressure data from a single-cylinder directin-jection engine and information about the specific heat ratio, gamma, of the injected fuel to predict the evaporated fuel mass in the piston-cylinder assembly. Thermodynamic theory and ideal gas laws are used to calculate theoretical pressure within the cylinder and this pressure is then compared to the actual pressure measured in the engine. The difference in gamma between the calculated and actual states of the fuel is then used to predict how much fuel has evaporated in the cylinder. This simplistic approach also takes into account information about the …
