Concept Of Local Polaritons And Optical Properties Of Mixed Polar Crystals, Lev I. Deych, Alexey Yamilov, Alexander A. Lisyansky

Physics Faculty Research & Creative Works

The concept of local polaritons is used to describe the optical properties of mixed crystals in the frequency region of their restrahlen band. It is shown that this concept allows for a physically transparent explanation of the presence of weak features in the spectra of so-called one-mode crystals and for one-two mode behavior. The previous models Were able to explain these features only with the use of many fitting parameters. We show that under certain Conditions new impurity-induced polariton modes may arise within the restrahlen of the host crystals, and study their dispersion laws and density of states. Particularly, we …

Algorithm Development For On-Line Control Of The Airborne Laser, Michael W. Oppenheimer

Theses and Dissertations

The use of adaptive optics entails the design of a controller. This requires the development of a model of the plant to be controlled, which, in this case, Consists of the atmosphere through which light is traveling. In optics, Zemike polynornials are used as a basis set for the expansion of wavefront phase distortions. Due to the turbulence induced stochastic nature of the underlying process involved, the spatial-temporal correlation functions of the Zemike polynomial phase expansion coefficients must be evaluated if a proper stochastic model of the plant is to be developed and adaptive optics is to be employed. In …

Validation And Verification Of Formal Specifications In Object-Oriented Software Engineering, Steven A. Thomson

Theses and Dissertations

The use of formal specifications allows for a software system to be defined with stringent mathematical semantics and syntax via such tools as propositional calculus and set theory. There are many perceived benefits garnered from formal specifications, such as a thorough and in-depth understanding of the domain and system being specified and a reduction in user requirement ambiguity. Probably the greatest benefit of formal specifications, and that which is least capitalized upon, is that mathematical proof procedures can be used to test and prove internal consistency and syntactic correctness in an effort to ensure comprehensive validation and verification (V&V). The …

Cattle Lack Vascular Receptors For Escherichia Coli O157:H7 Shiga Toxins, Ingrid M. Pruimboom-Brees, Tim W. Morgan, Mark R. Ackermann, Evelyn A. Dean-Nystrom, James E. Samuel, Nancy A. Cornick, Harley W. Moon

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Escherichia coli O157:H7 causes Shiga toxin (Stx)-mediated vascular damage, resulting in hemorrhagic colitis and the hemolytic uremic syndrome in humans. These infections are often food-borne, and healthy carrier cattle are a major reservoir of E. coli O157:H7. We were interested in knowing why cattle are tolerant to infection with E. coli O157:H7. Cattle tissues were examined for the Stx receptor globotriaosylceramide (Gb₃), for receptivity to Stx binding in vitro, and for susceptibility to the enterotoxic effects of Stx in vivo. TLC was used to detect Gb3 in tissues from a newborn calf. Gb₃ was detected …

Review Of Eva Kocziszky, Mythenfiguren In Hölderlins Spätwerk, Priscilla A. Hayden-Roy

German Language and Literature Papers

Kocziszky attempts to explicate the function of the Greek myths in Hölderlin’s late writings, primarily the annotations to his translations of Sophocles’s Oedipus and Antigone. She interprets these myths broadly, and in her discussions explores the figures of the centaur (here her textual basis is “Das Belebende,” Hölderlin’s translation and commentary of one of the Pindaric fragments), Oedipus, Antigone, Danae, and the “Muse,” Greece itself, as tragic figures whose significance emerges as one considers their relationship to the poetological, historical, political, and also profoundly personal concerns expressed in Hölderlin’s work. Following Jean LaPlanche’s observation that poetry and disease share a …

An Investigation Of Thread Scheduling Heuristics For A Simultaneous Multithreaded Processor, Ralph Zajac Jr

Theses

Over the years, the von Neumann model of computing has undergone many enhancements. These changes include an improved memory hierarchy, multiple instruction issue and branch predic tion. Since the model's introduction, the performance of processors has increased at a much greater rate than that of memory. Several modifications to hide this ever widening gap in performance are being examined in current research. A very promising one is the Simultaneous Multithreaded processor. This architecture strives to further reduce the effects of long latency instructions, such as memory accesses, by allowing multiple threads of execution to be active in the processor at …

Tiller Recruitment Patterns And Biennial Tiller Production In Prairie Sandreed, J. R. Hendrickson, Lowell E. Moser, Patrick E. Reece

Department of Agronomy and Horticulture: Faculty Publications

Tiller recruitment is an essential process for ensuring the perenniality of grasses. The timing and extent of tiller recruitment and the role of biennial tillers must be documented for key range species. Prairie sandreed [Calamovilfa longifolia (Hook) Scribn.] is an important grass in the Nebraska Sandhills for both ecological functioning and as a forage. The objective of this study was to document tiller recruitment patterns and the occurrence and contribution of current year and biennial tillers to biomass production in prairie sandreed at 2 locations in Nebraska. Tiller recruitment was monitored at 2-week periods throughout the growing season during …

Religiopoiesis, Ursula Goodenough

Biology Faculty Research

Religiopoiesis describes the crafting of religion, a core activity of humankind. Each religion is grounded in its myth, and each myth includes a cosmology of origins and destiny. The scientific worldview coheres as such a myth and calls for a religiopoietic response. The difficulties, opportunities, and imperatives inherent in this call are explored, particularly as they impact the working scientist.

The Development Of Family Ministry For The Local Church, Daryl W. Pitts

Doctoral Dissertations and Projects

All social and cultural indications demonstrate that the American society is in desperate need. Divorce rates and addictions have multiplied both within and without the church. The local church is uniquely positioned to offer hope and healing, from a biblical perspective to those who have been beaten, bruised, and left beside the freeway of the New World Order. The local church also has the ability to provide preventative services so its members can avoid these life hazards. Based on surveys and research, this project presents a strategy to implement a comprehensive professional pastoral Christian counseling service for the local church.

Hair Transplantation, Yousef M. Al-Khair

Saudi Medical Journal

Hair transplantation is a technique in which hair follicles are harvested from the occipital area and re-transplanted in the frontal bald area. Hair transplantation is the most common cosmetic procedure in the United States nowadays despite the fact that it is expensive. Usually, patients need more than one session to receive a cosmetically acceptable result and patients need to be understanding and have realistic expectations. Although most of our patients are males, females represent about 10-15% of our new patients. This article reviews the basic principals of hair transplantation and describes new and improved techniques of hair transplantation.

Analyzing East/West Power Politics In Comparative Cultural Studies, William H. Thornton

CLCWeb: Comparative Literature and Culture

In his article, "Analyzing East/West Power Politics in Comparative Cultural Studies," William H. Thornton acknowledges culture as a central force on the geopolitical map and undertakes at once to preserve the strategic potency of political realism and to move beyond the "billiard ball" externality of both neo- and traditional realisms. Although Huntington and Fukuyama are taken seriously on the question of East/West power politics, Thornton develops a world view by grounding balance-of-power politics in national and local (not just civilizational) social reality. Further, Thornton argues against external democratic teleologies both Huntington and Fukuyama have imposed on the cultural Other. The …

The Hazard Of Hidden Interactions: A Reanalysis Of Designs In Reaction-Time Studies On Metaphor, Johan F. Hoorn

CLCWeb: Comparative Literature and Culture

In his article, "The Hazard of Hidden Interactions: A Reanalysis of Designs in Reaction-Time Studies on Metaphor," Johan F. Hoorn argues that research designs in empirical literature and the psychology of aesthetics often include unanalyzed factors. The nature of these factors may be linguistic such as word frequency or lexical ambiguity or technical such as presentation order, repeated measures, etc. By not correctly analyzing an experiment, higher-order interactions may go unnoticed, while interfering with results. Hoorn reviews a sample of reaction-time experiments on metaphors, some of which are considered key studies in the area. Because the quality of an argument …

A Dynamic Optimal Trajectory Generator For Cartesian Path Following, Edward Red

Faculty Publications

This paper considers a dynamic and adaptive trajectory generator for negotiating paths using S-curves. Applying constant jerk transitions between the constant acceleration and deceleration periods of the trajectory, the trajectory will optimally transition to the desired speed setting. Optimal is defined to be the minimum time to transition from the current speed to the set speed for the move segment when jerk and acceleration are limited. The S-curve equations will adapt to instantaneous changes in speed setting and path length. An integrated motion planner will determine allowable speeds and transitional profiles based on the remaining move distance.

On The Assignment Of Gender To Chicano Anglicisms: Processes And Results, Robert N. Smead

Faculty Publications

The creation of neologisms through linguistic borrowing is a complex process. For donor language models to be transformed into host language replicas, phonological and morphological adaptation must take place. Part and parcel of that adaptation is the assignment of gender to loanwords in a host language like Spanish. The present article examines gender assignment in two corpora of loanwords (New Mexican and Southern Colorado Spanish: N=212 and General Chicano Spanish: N=595). Through the application of variable rule methodology (GoldVarb 2), five factors are posited as significant. Two of these categorically determine gender assignment when present: (1) the biological sex of …

The Creation Of Typographic Specifications For Desktop Publishing Software, Michelle Hill

Theses

As computers become more abundant in the home and office, more people are performing tasks that once would have been done by a skilled professional. Computers and software programs have become easier to use, including desktop publishing programs. Programs are now available that allow anyone to "become a designer." Through this, however, most typographers agree, the typographic quality of documents has suffered. Many companies are now designing their own media, in an effort to save money. The documents they create are adequate, but there is something missing. Though they may not be able to explain why, most people can appreciate …

A Science-Based Initiative To Manage Double-Crested Cormorant Damage To Southern Aquaculture, James F. Glahn, Mark E. Tobin, Bradley F. Blackwell

United States Department of Agriculture Wildlife Services: Staff Publications

Aquaculture has expanded rapidly in the Southern United States during the past two decades, especially the cultivation of catfish, crawfish, and bait fish. These fish usually are cultivated on farms with extensive systems of large shallow ponds that are highly susceptible to predation by birds. Double-crested cormorants (Phalacrocorax auritus ), American white pelicans (Pelecanus erythrorhynchos ), wading birds (e.g., Ardea alba, Ardea herodius ), and scaup (Aythya spp. ) are among the birds most frequently implicated. Well-documented problems associated with cormorant predation on catfish farms have coincided with the increase of this industry and the rapid …

Community Support For Natural Resource Management. Future Frameworks: Future Needs, Fionnuala Frost, Wendy Dymond, Soil And Land Conservation Council Of Western Australia

Natural resources published reports

A report prepared for the Soil and Land Conservation Council of Western Australia.

Emerging from the Decade of Landcare is growing recognition that regional and local community involvement is integral to the success of any natural resource management (NRM) outcome. It is integral for a number of reasons:

1. Community support provides the capacity to develop plans and strategies at local, regional scale which are owned by the community who review (technical recommendations, advice and information and adapt them to suit local need;

2. Community knowledge provides an important balance to research knowledge and State and regional level strategies and …

Making A Difference: Human Service Interest Group Influence On Social Welfare Program Regulations, Richard Hoefer

The Journal of Sociology & Social Welfare

Social workers increasingly understand the importance of political action to affect legislative policy-making. This paper sheds light onto the unexplored subject of interest group influence on the executive branch, specifically on the writing of program regulations for social welfare programs. It describes groups active in the process and what they do in their quest for influence. It also presents a preliminary model of interest group influence on regulation writing. Results show that having greater access, articulating a liberal policy position, choosing a "better" strategy and devoting more resources to influence efforts are all significant predictors of a group's influence level …

Pathways To Prison: Life Histories Of Former Clients Of The Child Welfare And Juvenile Justice Systems, Stephen A. Kapp

The Journal of Sociology & Social Welfare

This study examines the relationship between child maltreatment and future offending from the viewpoint of former clients. Imprisoned adults describe their experiences in child welfare and juvenile justice system services. Specifically, those placed out of the home originally into the child welfare system have a different perspective on their path to prison than those placed into the juvenile justice system as delinquents. The study contributes to the literature by examining the relationship between the services children receive in the child welfare system as well as the juvenile justice system and their imprisonment as adults from a former service recipient's point …

Urban Violence Among African American Males: Integrating Family, Neighborhood, And Peer Perspectives, M. Daniel Bennett Jr., Mark W. Fraser

The Journal of Sociology & Social Welfare

Even though rates have declined in recent years, violence is a serious problem in many American cities. This paper reviews recent perspectives on violence among young, urban African American males. Special attention is afforded the "father absent" hypothesis, the effect of poverty, the character of neighborhoods, the roots of self-efficacy, and peer influence, particularly the influence of street codes. The latter are argued both to regulate some situational behavior and to promote the use of violence in disputes over social status, drugs, and money. The authors discuss implications for policy and community development.

Knowledge Discovery In Biological Databases : A Neural Network Approach, Qicheng Ma

Dissertations

Knowledge discovery, in databases, also known as data mining, is aimed to find significant information from a set of data. The knowledge to be mined from the dataset may refer to patterns, association rules, classification and clustering rules, and so forth. In this dissertation, we present a neural network approach to finding knowledge in biological databases. Specifically, we propose new methods to process biological sequences in two case studies: the classification of protein sequences and the prediction of E. Coli promoters in DNA sequences. Our proposed methods, based oil neural network architectures combine techniques ranging from Bayesian inference, coding theory, …

Axisymetric Vibrations Of Homogeneous And Sandwich Spherical Shells With A Hole At The Center, Wai-Kwong Wong

Dissertations

Based on Hamilton's principle and the theory of elasticity, both linear and nonlinear governing equations of motion are derived for elastic spherical shells. Most of the analysis is focused on the free axisymmetric vibrations of homogeneous and sandwich shallow spherical shells. The nonlinear behavior, which allows for small deflections, is also discussed.

The linear vibrations of homogeneous and sandwich shallow spherical shells with a hole at the center are investigated with emphasis placed on the effect of thickness-shear deformation and rotatory inertia. The effects of curvature and the size of the central hole are studied for free axisymmetric motions of …
