A Genetic-Based Approach To Multi-Layer Channel Routing In Vlsi Design., Mark P. Cloyed
A Genetic-Based Approach To Multi-Layer Channel Routing In Vlsi Design., Mark P. Cloyed
Student Work
As our reliance on electric and electronic devices increases, the need to improve the design and manufacture of integrated circuits (ICs) grows. A microchip can be bettered if it can be made more powerful, smaller, cheaper, and/or more easily manufactured. The physical design phase of chip manufacture offers significant room for improvement. This thesis intends to investigate the detailed channel routing phase of VLSI physical design. Channel routing has been seen to be intractable, in that an optimal solution may require too much time for calculation. Constraints severely limit many algorithms to an approximate solution. The heuristics developed thus far …

Five Women In American Politics Spanning 1917-1993 A Rhetorical Criticism Of News-Coverage From The New York Times, Sarah T. May
Student Work
Like the air we breathe, the media permeate our society. Twenty-four hours a day news and information is available from all reaches of the earth. Because the majority of our knowledge of the world around us comes from the media, they have tremendous power over how people, places and events are perceived (Graber, 1997). Whether the story publicizes controversial issues such as same-sex marriage, or tugs at patriotic themes like flag burning, by giving air times or column inches, media imply certain values and beliefs and newsworthy. In a democratic society, media do not say what to think, but highlighting …
A Study Of The Sublime In English Romantic Aesthetics, Derek T. Leuenberger
A Study Of The Sublime In English Romantic Aesthetics, Derek T. Leuenberger
Student Work
The nature and role of sublime experience has been an enduring topic of discussion in the history of aesthetics, dating back nearly 2000 years to the rhetorical sublime of Longinus. The emergence of English romanticism at the juncture of the eighteenth and nineteenth centuries wrought substantial change on conceptions of the sublime, driven primarily by Immanuel Kant’s transcendental philosophy. Samuel Taylor Coleridge, William Wordsworth, and Percy Bysshe Shelley each develop a theory of sublimity grounded in the expression of unified and universal experience in human consciousness. Naturally, certain philosophical differences arise within the theoretical discourse of the authors - most …

Student Work
A plant community gradient, consisting of Open-water, bulrush, Grass, and Forest Zones, was evaluated both before (1995) and one-year after (1997) restoration-dredging of a wetland along the Missouri River in east-central Nebraska. Species diversity declined significantly (P ≥ 0.05) in both the Bulrush and Grass Zones (-24 and -30 species) but not elsewhere. The Open-water Zone, which increased the most with dredging (+40 meters), was dominated by duckweed (Lemna minor) (53% canopy cover in 1995 and 45% in 1997) and watermeal (Wolddia columbiana) (53% and 61%) both before and after dredging. Coontail (Ceratophylum demersum) increased significantly (7% to 25%). The …

The Relationship Between Cynicism And Dispositional Attributions: Examining Individual Differences Of Police Officers, Jennifer L. Weimer
Student Work
Previous research has shown that veteran police officers are more cynical than less experienced police officers. Research has also shown that veterans are more likely than less experienced officers to make dispositional attributions for the actions of suspects in interpersonal disputes. This study examined these two premises and the relationship between cynicism and attributions. Participants included 127 police officers and 70 undergraduate students who completed a cynicism scale and were then asked to read two scenarios depicting interpersonal disputes. Participants answered several questions pertaining to their attributions of responsibility and their perceptions of credibility of the suspect and the victim …
Communication And Migration: How Communication Influences The Human Economy, Carol Napolitano
Communication And Migration: How Communication Influences The Human Economy, Carol Napolitano
Student Work
Communication and migration are tied through the common concept of community. Communication is the nervous system of a community, transmitting shared ideals, goals, and norms among citizens. Communication also is the process by which a community projects its identity or image to the outside world to attract new individuals who will nourish it economically and socially. Despite this deep connection between communication and community, migration research seldom incorporates communication theory. Likewise, communication scholars rarely look at the process of migration. The purpose of this thesis was to establish those theoretical links between communication and migration, look at how communication has …
