Simulation Study Of Mobile Computing Protocols, Syed Alamdar Ahson

Electronic Theses and Dissertations 1990 - 1999

With the advent of cellular technology and portable computers we are on the verge of a new computing paradigm. This computing paradigm is now widely known as "mobile" or "nomadic" computing. Mobile systems frequently change their point of attachment to the network. Mobile computing systems also need to communicate with the existing pool of information and file servers. Mobility defies the very principles that the TCP/IP protocol suite is based on. We study the Internet Engineering Task Force (IETF) Mobile IPv4 protocol and find it to be a highly scale solution. We study some of the other proposed mobile IP …

Second Order Leaky Bucket Algorithm For Traffic Shaping In Atm Networks, Atul. Bansal

Electronic Theses and Dissertations 1990 - 1999

Asynchronous Transfer Mode (ATM) Networks are based on connections that are multiplexed dynamically on a single link. For satisfactory performance in an ATM network, congestion control is extremely necessary to guarantee the negotiated Quality of Service (QoS) for every connection. Traffic shaping is a congestion control mechanism that alters the traffic characteristics of a stream of cells on a connection to achieve better network efficiency by meeting the QoS objectives. We study a model for Traffic Shaping, Second Order Leaky Bucket, which consists of two leaky buckets to police the Sustained Cell Rate (SCR) and Burst Tolerance (BT) for each …

Sediment Layer Tracking Using Neural Networks, Vincent Nicolas Freyermuth

Electronic Theses and Dissertations 1990 - 1999

The detection of sediment layer interfaces in normal incidence acoustic reflection data is a requirement for automatic classification and geologic mapping of subsurface layers. The detection is difficult because of the constructive and destructive interference caused by the impedance changes in the sediment column and high scattering noise levels. The purpose of this work is to implement a procedure using neural networks that automatically detects the sediment layers from the envelope of acoustic reflections. The data was collected using a sub-bottom profiler that transmits a 2 to 10 kHz FM pulse. The detection procedure is a three step method: a …

The Effect Of Choline Supplementation On Maze Running Ability In Hypothyroid Rats, Jessica Ramer

Electronic Theses and Dissertations 1990 - 1999

The effects of perinatal hypothyroidism and perinatal choline supplementation on radial arm maze performance were assessed. Animals were made hypothyroid by the administration of propylthiouracil (PTU) to the mash of dams from prenatal day 15 until postnatal day 15. Choline chloride was administered prenatally in drinking water and postnatally through injections to the pups until day 24. Hypothyroid animals made significantly more reference and working memory errors than did euthyroid animals. Perinatal choline supplementation reduced the number of working memory errors, but not reference memory errors, in both euthyroid and hypothyroid animals.

Study Of Teacher Change And Its Meaning, Eileen W. Wills

Electronic Theses and Dissertations 1990 - 1999

The purpose of this study was to investigate how teachers change from being disseminators of information in teacher-centered classrooms and become constructive classroom change agents using a more facilitative teaching style in a learner-centered classroom. The study identified the forces that lead to change and examined what this change means for teachers. It included teachers who have made positive improvements by changing or broadening their instructional practices. This qualitative study examines one important reform program in a district of over 217,000 students. Twenty teachers were interviewed and observed who had participated in a two-year training program, TEAMS (Teachers Exploring and …

The Development, Implementation, And Evaluation Of A Strategic Prejudice Reduction Framework And Its Effect On Dogmatism Levels Of College Students, Ilene Allgood

Electronic Theses and Dissertations 1990 - 1999

Dogmatism is an uncritical, rigid way of thinking that correlates strongly with prejudice. Prejudice is an attitude, usually unfavorable, toward individuals or groups, arrived at through an uncritical thought process and a disregard of the facts. Dogmatism, because of its connection with prejudice, vitiates students' chances for learning. Dogmatism in teachers creates an inequitable distribution of education to the extent that marginalized minority students are shortchanged educational opportunities. The nature of dogmatism and its impact on education is covered in the literature. Moreover, pedagogical and andragogical strategies which utilize the cognitive and affective domains to heighten critical thinking ability and …

Temporal Organization Of Memory Strategies On A Sort/Recall Task, Cynthia Louise Smith Park

Electronic Theses and Dissertations 1990 - 1999

This study examined the temporal structure of children's study behaviors on a sort/recall task. Forty-two fifth-grade children were given six sort/recall trials, each consisting of a two-minute study period followed by a recall assessment. Three trials used the same word list on each trial, while three trials used different word lists on each trial. Half of the participants received the different word list trials first while the order was reversed for the remaining participants. Results were analyzed for differences between recall groups, type of word list used, and presentation order of the trials. High recallers demonstrated stronger temporal patterns of …

Value Of Collaboration Between A Nurse Practitioner And Physician, Helena E. Azzi

Watershed Delineation In A Low Topographic Relief Landscape Of South Florida, Michael T. Rose

Electronic Theses and Dissertations 1990 - 1999

Watershed delineations in low topographic relief landscapes with canal networks require hydrography. This hypothesis was tested by utilizing digital elevation models (DEMs). Seven DEMs were processed using two automated delineation methods. Both methods include filling of localized sinks, but an enhanced method incorporated incremental "tipping" to provide flow direction. In two watersheds studied, DEMs with only topography delineated watersheds within 24% and 84% of the manual delineation. With the addition of hydrography, including canals, both watersheds were delineated to within 85% and 92% of the manual delineation. Contrary to the assumption that tipping would improve delineation, tipping decreased the delineated …

Very Strange Doctrine: The Natural Right Of Resistance In John Locke's "Second Treatise Of Government", John Patrick Mullins

Electronic Theses and Dissertations 1990 - 1999

Within his own intellectual context, John Locke's argument for the people's natural right of resistance in the Second Treatise of Government was profoundly original. But he derived its conceptual foundation and rhetorical ornament from the six political texts immediately available to him when he wrote the Second Treatise in 1681-82. Locke based his "very Strange Doctrine" of popular resistance to political tyranny upon the natural right of rational individuals to judge and punish criminals in the state of nature. Textual analysis demonstrates that none of his six texts presented this argument. Locke did, however base his resistance theory upon such …

West German Secondary School Education On The Holocaust, Martin Eric Vann

Electronic Theses and Dissertations 1990 - 1999

After World War II, Germany lay in ruins, both physically and morally. The Allies attempted denazification, but were unable to completely reform the educational system. Cold War exigencies dictated that lessons on the Nazi era, particularly the cruelties of the Holocaust, be soft-pedaled. While some German politicians urged greater openness, collective amnesia reigned for over a decade. Early texts showed Germans as mesmerized by Hitler, who, together with a few henchmen, was responsible for the mass murders. Gradually, as democracy took root in West Germany, educators responded to the changing political culture by teaching more of the true nature of …

Deconstructing The Distinction Between Bias And Merit, Daria Roithmayr

Publications

In this article Professor Roithmayr attempts to develop in the context of law school admissions a theoretical argument from deconstruction to support the radical critique of merit. The radical critique, espoused primarily by Critical Race Theorists and radical feminists, argues that merit standards disproportionately exclude white women and people of color because merit standards were developed by dominant social groups, in ways that have disproportionately benefited their descendants. Using a critical history of law school admission standards, as well as a deconstructive reading of a defense of merit offered by Professors Daniel Farber and Suzanna Sherry, Professor Roithmayr deconstructs the …

Patterns Of Time, Place, And Culture: Land Use Zoning In Portland, Oregon, 1918-1924, Meg Merrick

Dissertations and Theses

Until recently, few have questioned the notion that the separation of uses in land use zoning is inherently correct. Many observers of the city are now suggesting that zoning, as it has been practiced in this country over the last 80 years, has created cities that are fractured and function poorly. Others propose that zoning should be reconsidered as a remedy for urban dysfunction. They suggest that the whole notion of zoning be rethought.

The purpose of this study is to uncover some of the underlying rationales and methodologies that set the model for zoning. This study examines the rationales …

Negotiation And Reorganization Of Peer Relationships During Adolescence: The Emergence Of Romantic Relationships And Quality Of Peer Relationships, Melanie Jo Zimmer-Gembeck

Dissertations and Theses

Research suggests that, for adolescent females, the initiation of romantic relationships is a normative developmental task and a task associated with potential difficulties, including physical aggression. Most previous research treats progress in this task as a function of individual characteristics. This study assumes that when girls are negotiating romantic relationships, they have existing intimate friendships with other females, and these friendships are important to how this task is negotiated.

Females who recently graduated from high school provided retrospective and current information on the amount of leisure time spent with members of their social networks, qualities of relationships in later adolescence, …

The Use Of Red Mud/Gypsum To Reduce Water Pollution From Sandy Soils Used For Vegetable Production, Ian Mcpharlin, W. J. Robertson, R. C. Jeffery

Research Reports

An important domestic and export vegetable industry is located on the sands of the Swan Coastal Plain (SCP) in Western Australia. The total value of the vegetable industry on the SCP was estimated at $90M in 1996/7 or about 50% of the total value of the industry. This vegetable production has been located on good quality sands such as the Spearwood and yellow Karrakatta sands, close to the coast, since the 1950s. However in recent years competition for this land for urban and industrial use has forced vegetable production onto soils with poorer water and phosphorus retention capacity such as …
