Visualization Of Internet Web Pages Based On Authority And Word Frequency, David Navarro Dec 2003

Visualization Of Internet Web Pages Based On Authority And Word Frequency, David Navarro

Theses and Dissertations - UTB/UTPA

The growth, accessibility, and integration of the World Wide Web with contemporary information utilization provides a rich domain in which to explore information retrieval systems. One approach in the evolution of retrieval systems couples successful and long-standing techniques of information retrieval with new techniques, such as visualization. The system developed and reported in this thesis takes this approach. It builds upon well-known techniques of information retrieval including stemming, keyword matching, and cosine similarity. It also incorporates the new and relatively successful hubs and authority approach, which describes Web documents by their reference by other documents. Finally, it develops a new …


Claus/Claws: A Journey Through Leonardland's Multivalent Meanings, Chris Leonard Dec 2003

Claus/Claws: A Journey Through Leonardland's Multivalent Meanings, Chris Leonard

Theses and Dissertations - UTB/UTPA

This exhibition paper presents the linkage of apparently unrelated topic and content. This arduous task is accomplished through an exploration of opposites and an overall presentation in the form of family fun or domestic distress disguised within personal world and the overall umbrella of homonyms: Claus (as in Santa) and Claws (as in cat). The work presented is a view of Leonardland, an intensely personal vision of my family and our history melded into a proposed future as seen through a wild conglomeration of seemingly dissimilar visions comprising the eclectic cultural mix that is our life on this geographic and …

Eight most parsimonious trees 569 steps long were obtained, with a consistency index of 72%. Groups in the tree are not congruent with those in previous classification schemes of species in the genus, based on a small number of morphological characters. For this subset of Haematoloechus,/i> species, plesiomorphic hosts are …


Experimental Evaluation Of Constraint Automata Solutions To The Genome Map Assembly Problem, Viswanathan Ramanathan Dec 2003

Experimental Evaluation Of Constraint Automata Solutions To The Genome Map Assembly Problem, Viswanathan Ramanathan

School of Computing: Dissertations, Theses, and Student Research

DNA sequences are really huge having a length of around 3-4 million base pairs. Hence, each DNA sequence has to be cut down into small fragments using restriction enzymes. Once analyzed, these fragments have to be arranged or assembled into a single set of sequences called a genome map, to obtain the original DNA sequence. This problem is called the Genome Map Assembly Problem. A Constraint-Automata Solution was proposed for this purpose [11]. This thesis improves and implements the Constraint-Automata Solution to find all the possible solutions. The Modified Constraint-Automata Solution was implemented in Perl and executed on parts of …

The Virtues Of Knowing Less: Justifying Privacy Protections Against Disclosure, Daniel J. Solove Dec 2003

The Virtues Of Knowing Less: Justifying Privacy Protections Against Disclosure, Daniel J. Solove

Duke Law Journal

This Article develops justifications for protections against the disclosure of private information. An extensive body of scholarship has attacked such protections as anathema to the Information Age, where the free flow of information is championed as a fundamental value. This Article responds to two general critiques of disclosure protections: (1) that they inhibit freedom of speech, and (2) that they restrict information useful for judging others. Regarding the free speech critique, the Article argues that not all speech is of equal value; speech of private concern is less valuable than speech of public concern. The difficulty, however, is distinguishing between …


Modularity And The Product Lifecycle, Peter Cebon, Oscar Hauptman, Chander Shekhar Dec 2003

Modularity And The Product Lifecycle, Peter Cebon, Oscar Hauptman, Chander Shekhar

Research Collection Lee Kong Chian School Of Business

Product lifecycle theory, which underlies theories of technical innovation in economics, strategy, marketing, and operations management, is based implicitly on the assumption that products are integrated wholes. The modularization of products undermines the specific synergies which drive the product lifecycle, and this undermining has impacts spanning from the structure of individual organizations to the structure of economies and the definition of industries.

Design And Development Of A Lubrication Pump For A Horizontally Mounted Air-Conditioning Compressor., Kenneth T. Gilbert

Electronic Theses and Dissertations

Horizontally mounted compressors offer the advantage of reduced height in central air-conditioning units but prove difficult to produce economically due to costs associated with the manufacture of acceptable lubrication systems for the compressors. This study develops an effective, affordable oil pump for use on a horizontal compressor. Concepts are proven through testing of prototype assemblies. Test results drive modifications for future prototypes, and prototypes demonstrating adequate performance are modified for ease of manufacture.

Research in this study proves that the most suitable design results from a modification of a rotating vane pump. The pump’s modifications enable it to pump oil …


County Agent Views About Facilitating Public Education And Discussion Of Genetic Engineering Use In Agriculture, J Lynne Brown, Nancy Ellen Kiernan, Elaine S. Smith, Luanne Hughes Dec 2003

County Agent Views About Facilitating Public Education And Discussion Of Genetic Engineering Use In Agriculture, J Lynne Brown, Nancy Ellen Kiernan, Elaine S. Smith, Luanne Hughes

Journal of Extension

We conducted seven focus groups with Extension agents from three northeast states in Spring 2000 to learn what agents knew about genetic engineering (GE) applications in agriculture, their view of Extension's role in public discussion and education, and the training needed to assume such a role. While participating agents together knew a fair amount about their target audiences' perceptions of GE, they felt unprepared to deal with the challenges of public issues education in light of the current public debate, the publics' low science literacy, and their own science background. Their expressed training needs reflected these challenges.


Least Squares Support Vector Machines For Direction Of Arrival Estimation With Error Control And Validation, Chaouki T. Abdallah, Judd A. Rohwer, Christos G. Christodoulou Dec 2003

Least Squares Support Vector Machines For Direction Of Arrival Estimation With Error Control And Validation, Chaouki T. Abdallah, Judd A. Rohwer, Christos G. Christodoulou

Electrical & Computer Engineering Faculty Publications

The paper presents a multiclass, multilabel implementation of least squares support vector machines (LS-SVM) for direction of arrival (DOA) estimation in a CDMA system. For any estimation or classification system, the algorithm's capabilities and performance must be evaluated. Specifically, for classification algorithms, a high confidence level must exist along with a technique to tag misclassifications automatically. The presented learning algorithm includes error control and validation steps for generating statistics on the multiclass evaluation path and the signal subspace dimension. The error statistics provide a confidence level for the classification accuracy.

Xstamps: A Multiversion Timestamps Concurrency Control Protocol For Xml Data, Khin-Myo Win, Wee-Keong Ng, Ee Peng Lim Dec 2003

Xstamps: A Multiversion Timestamps Concurrency Control Protocol For Xml Data, Khin-Myo Win, Wee-Keong Ng, Ee Peng Lim

Research Collection School Of Computing and Information Systems

With the tremendous growth of XML data over the Web, efficient management of such data becomes a new challenge for database community. Several data management solutions, proposed in recent years, extend the capability of traditional database systems to meet the needs of XML data while alternative approaches introduce new generation databases, named as native XML database management systems. Although traditional databases have mature transaction management and concurrency control techniques, there is still a need to tailor techniques for native XML databases in order to deal with distinct characteristics of XML. In this paper, we propose XStamps, a multiversion timestamps concurrency …

Predicting Nonlinear Network Traffic Using Fuzzy Neural Network, Zhaoxia Wang, Tingzhu Hao, Zengqiang Chen, Zhuzhi Yuan

Research Collection School Of Computing and Information Systems

Network traffic is a complex and nonlinear process, which is significantly affected by immeasurable parameters and variables. This paper addresses the use of the five-layer fuzzy neural network (FNN) for predicting the nonlinear network traffic. The structure of this system is introduced in detail. Through training the FNN using back-propagation algorithm with inertia] terms the traffic series can be well predicted by this FNN system. We analyze the performance of the FNN in terms of prediction ability as compared with solely neural network. The simulation demonstrates that the proposed FNN is superior to the solely neural network systems. In addition, …


Postcolonial African Consciousness And The Poetry Of Agostinho Neto, Irene Marques Dec 2003

Postcolonial African Consciousness And The Poetry Of Agostinho Neto, Irene Marques

CLCWeb: Comparative Literature and Culture

In her paper, "Postcolonial African Consciousness and the Poetry of Agostinho Neto," Irene Marques introduces the magic words of a great poet with the question: can poetry carry enough sorrow, enough strength, enough fire, enough love, enough wisdom, enough care, and enough horror to penetrate the hearts and the souls of the oppressed and the oppressors so that both will desperately want to escape their sinister labels? For Marques, this question represents an old quandary and one that many of us wish could be answered with a simple yes. Marques analyses Neto's poetry in the context of littérature engagé: if …


Comparative Literature Versus Comparative Cultural Studies, Tomo Virk Dec 2003

Comparative Literature Versus Comparative Cultural Studies, Tomo Virk

CLCWeb: Comparative Literature and Culture

In his paper, "Comparative Literature versus Comparative Cultural Studies," Tomo Virk discusses debates of the role, essence, and the future of comparative literature as it has developed since the 1995 publication of the Bernheimer Report. Virk explores the situation of the discipline in its North American context: "contextualists" argue for the abandoning of comparative literature understood as the study of literature with theoretical investigations of literariness while the "non-contextualists" underscore the study of the linguistic structure(s) of the text. Virk supports comparative literature understood as the traditional concentration of the discipline with focus on the specificities of literary questions while …

Multiple Uav Cooperative Search Under Collision Avoidance And Limited Range Communication Constraints, Randal W. Beard, Timothy W. Mclain Dec 2003

Multiple Uav Cooperative Search Under Collision Avoidance And Limited Range Communication Constraints, Randal W. Beard, Timothy W. Mclain

Faculty Publications

This paper focuses on the problem of cooperatively searching, using a team of unmanned air vehicles (UAVs), an area of interest that contains regions of opportunity and regions of potential hazard. The objective of the UAV team is to visit as many opportunities as possible, while avoiding as many hazards as possible. To enable cooperation, the UAVs are constrained to stay within communication range of one another. Collision avoidance is also required. Algorithms for team-optimal and individually-optimal/team-suboptimal solutions are developed and their computational complexity compared. Simulation results demonstrating the feasibility of the cooperative search algorithms are presented.


Parallel Microgenetic Algorithm Design For Photonic Crystal And Waveguide Structures, J. Cai, L. Li, Gregory P. Nordin, J. Jiang Dec 2003

Parallel Microgenetic Algorithm Design For Photonic Crystal And Waveguide Structures, J. Cai, L. Li, Gregory P. Nordin, J. Jiang

Faculty Publications

We have developed a powerful parallel genetic algorithm design tool for photonic crystal and waveguide structures. The tool employs a small-population-size genetic algorithm (microgenetic algorithm) for global optimization and a two-dimensional finite-difference time-domain method to rigorously design and optimize the performance of photonic devices. We discuss the implementation and performance of this design tool. We demonstrate its application to two photonic devices, a defect taper coupler to connect conventional waveguides and photonic crystal waveguides, and a sharp 90˚ waveguide bend for low index contrast waveguides.


Ultracompact High-Efficiency Polarizing Beam Splitter With A Hybrid Photonic Crystal And Conventional Waveguide Structure, J. Cai, S. Kim, Gregory P. Nordin, J. Jiang Dec 2003

Ultracompact High-Efficiency Polarizing Beam Splitter With A Hybrid Photonic Crystal And Conventional Waveguide Structure, J. Cai, S. Kim, Gregory P. Nordin, J. Jiang

Faculty Publications

We propose an ultracompact high-efficiency polarizing beam splitter that operates over a wide wavelength range and is based on a hybrid photonic crystal and a conventional waveguide structure. Within a small area (15 mm 3 10 mm), this polarizing beam splitter separates TM- and TE-polarized modes into orthogonal output waveguides. Results of simulations with the two-dimensional finite-difference time-domain method show that 99.3% of TM-polarized light is def lected by the photonic crystal structure (with a 28.0-dB extinction ratio), whereas 99.0% of TE-polarized light propagates through the structure (with a 32.2-dB extinction ratio). Wave vector diagrams are employed to explain the …


The Arms Trade In Russian-Chinese Relations: Identity, Domestic Politics, And Geopolitical Positioning, Robert H. Donaldson, John A. Donaldson Dec 2003

The Arms Trade In Russian-Chinese Relations: Identity, Domestic Politics, And Geopolitical Positioning, Robert H. Donaldson, John A. Donaldson

Research Collection School of Social Sciences

Why would a declining power help arm a neighboring and once-hostile rising power? Current international relations literature cannot explain relationships in which one powerful country contributes directly to its long-term relative decline in order to make smaller, short-term gains. This study focuses on one example, the Treaty on Good Neighborly Friendship and Cooperation between the Russian Federation and the People's Republic of China, signed in Moscow on July 16, 2001. Presenting evidence that this alliance embodies a relationship that is based primarily on sales of arms from Russia to China, the authors argue that this association cannot be explained by …

Cross sections for e+p charged current deep inelastic scattering at a centre-of-mass energy of 318 GeV have been determined with an integrated luminosity of 60.9 pb-1 collected with the ZEUS detector at HERA. The differential cross sections dσ/dQ2, dσ/dx and dσ/dy for Q2 > 200 GeV2 are presented. In addition, d2σ/dxdQ2 has been measured in the kinematic range 280 GeV2 < Q2 < 17 000 GeV2 and 0.008 < x < 0.42. The predictions of the Standard Model agree well with the measured cross sections. The mass of the W boson propagator is determined to be MW = 78.9 ± 2.0 (stat.) ± 1.8 (syst.) -1.8+2.0 (PDF) GeV from a fit to dσ/dQ2. The chiral structure of the Standard Model is also investigated in terms of the (1-y)2 dependence of the double-differential cross section. The structure-function F2CC has been extracted by combining the measurements presented here with previous ZEUS results from e-p scattering, extending the measurement obtained in a neutrino-nucleus scattering experiment to a significantly higher Q2 region.
