A Christian Perspective On Mathematics – History Of Mathematics And Study Guides, Johan Deklerk
A Christian Perspective On Mathematics – History Of Mathematics And Study Guides, Johan Deklerk
ACMS Journal 2004
This paper addresses two questions: (1) Will a study of the history of the subject serve any purpose in promoting a Christian perspective on mathematics? (2) Can the "science in context" approach be of further help in promoting such a perspective? The author answers both positively and provides specific examples of how he has done this in his own classes.

Thesis Digest: Mathematical Interpretation Of Political Power And The Arkansas State Government, Andrew King
Thesis Digest: Mathematical Interpretation Of Political Power And The Arkansas State Government, Andrew King
Inquiry: The University of Arkansas Undergraduate Research Journal
On the whole, political power can he very difficult to quantify. A person may be powerful due to his or her personal charm, wealth, fame, credibility, or influential connections. Political bodies do not account for these qualities when creating voting procedures; they only assign voting rules to specific positions. For example, most would say that in the United States government that a Senator is more powerful than a Representative, but less powerful than the President, without knowing any way to quantify or verify those differences. Since the 1950's, mathematicians and political scientists have attempted to create mathematical models that partially …
Privacy-Preserving Collaborative Filtering Using Randomized Perturbation Techniques, Huseyin Polat, Wenliang Du
Privacy-Preserving Collaborative Filtering Using Randomized Perturbation Techniques, Huseyin Polat, Wenliang Du
Electrical Engineering and Computer Science - All Scholarship
Collaborative Filtering (CF) techniques are becoming increasingly popular with the evolution of the Internet. E-commerce sites use CF systems to suggest products to customers based on like-minded customers' preferences. People use CF systems to cope with information overload. To conduct collaborative filtering, data from customers are needed. However, collecting high quality data from customers is not an easy task because many customers are so concerned about their privacy that they might decide to give false information. CF systems using these data might produce inaccurate recommendations. We propose a randomized perturbation technique to protect users' privacy while still producing accurate recommendations. …
Interacting Data Services For Distributed Earthquake Modeling, Marlon Pierce, Choonhan Youn, Geoffrey C. Fox
Interacting Data Services For Distributed Earthquake Modeling, Marlon Pierce, Choonhan Youn, Geoffrey C. Fox
Electrical Engineering and Computer Science - All Scholarship
We present XML schemas and our design for related data services for describing faults and surface displacements, which we use within earthquake modeling codes. These data services are implemented using a Web services approach and are incorporated in a portal architecture with other, general purpose services for application and file management. We make use of many Web services standards, including WSDL and SOAP, with specific implementations in Java. We illustrate how these data models and services may be used to build distributed, interacting applications through data flow.
An Adaptive Qos Routing Protocol With Dispersity For Ad-Hoc Networks, Youngki Hwang, Pramod Varshney
An Adaptive Qos Routing Protocol With Dispersity For Ad-Hoc Networks, Youngki Hwang, Pramod Varshney
Electrical Engineering and Computer Science - All Scholarship
In this paper, we present the design and simulation of a bandwidth constrained multiple path on-demand routing protocol for ad-hoc networks to support end-to-end Quality of Service, which is known as the Adaptive Dispersity QoS Routing (ADQR) Protocol. We propose a route discovery algorithm to find multiple disjoint paths with longerlived connections, where each path also specifies associated network resource information. This provides an efficient approach for network resource reservation combined with data dispersion and for route maintenance. A longerlived path generally involves less route maintenance, resulting in an increase of bandwidth utilization. We propose a route maintenance algorithm to …

Building Problem Solving Environments With Application Web Service Toolkits, Choonhan Youn, Marlon Pierce, Geoffrey C. Fox
Building Problem Solving Environments With Application Web Service Toolkits, Choonhan Youn, Marlon Pierce, Geoffrey C. Fox
Electrical Engineering and Computer Science - All Scholarship
Application portals, or Problem Solving Environments (PSEs), provide user environments that simplify access and integrate various distributed computational services for scientists working on particular classes of problems. Specific application portals are typically built on common sets of core services, so reusability of these services is a key problem in PSE development. In this paper we address the reusability problem by presenting a set of core services built using the Web services model and application metadata services that can be used to build science application front ends out of these core services.

Discovery Of Functional And Approximate Functional Dependencies In Relational Databases, Ronald S. King, James J. Legendre
Discovery Of Functional And Approximate Functional Dependencies In Relational Databases, Ronald S. King, James J. Legendre
Computer Science Faculty Publications and Presentations
This study develops the foundation for a simple, yet efficient method for uncovering functional and approximate functional dependencies in relational databases. The technique is based upon the mathematical theory of partitions defined over a relation's row identifiers. Using a levelwise algorithm the minimal non-trivial functional dependencies can be found using computations conducted on integers. Therefore, the required operations on partitions are both simple and fast. Additionally, the row identifiers provide the added advantage of nominally identifying the exceptions to approximate functional dependencies, which can be used effectively in practical data mining applications.

A Memory-Based Approach To Cantonese Tone Recognition, Deryle W. Lonsdale, Michael Emonts
A Memory-Based Approach To Cantonese Tone Recognition, Deryle W. Lonsdale, Michael Emonts
Faculty Publications
This paper introduces memory-based learning as a viable approach for Cantonese tone recognition. The memorybased learning algorithm employed here outperforms other documented current approaches for this problem, which is based on neural networks. Various numbers of tones and features are modeled to find the best method for feature selection and extraction. To further optimize this approach, experiments are performed to isolate the best feature weighting method, the best class voting weights method, and the best number of k-values to implement. Results and possible future work are discussed.

Indirect Symbolic Correlation Approach To Unsegmented Text Recognition, George Nagy, Sharad C. Seth, Y. Lin, Shashank K. Mehta
Indirect Symbolic Correlation Approach To Unsegmented Text Recognition, George Nagy, Sharad C. Seth, Y. Lin, Shashank K. Mehta
School of Computing: Conference and Workshop Papers
The new non-parametric approach to unsegmented text recognition builds two bipartite graphs that result from the feature-level and lexical comparisons of the same word against a reference string which need not include the query word. The lexical graph preserves the relative order of edges in the feature graph corresponding to correctly recognized features. This observation leads to a subgraph-matching formulation of the recognition problem. An initial implementation proves the robustness of the approach for up-to 20% noise introduced in the feature-level graph.

Computer Science: Faculty Publications and Other Works
This interdisciplinary project explores the potential for handheld/wireless (H/W) technology in the context of language education within and beyond the classroom. Specifically, we have designed and implemented a suite of multi-platform (desktop/laptop, handheld, and browser) applications to enhance the teaching of South Asian languages such as Hindi-Urdu. Such languages are very difficult to learn, let alone write, and H/W devices (with their handwriting/drawing capabilities) can play a significant role in overcoming the learning curve. The initial application suite includes a character/word tracer, a word splitter/joiner, a smart flashcard with audio, contextual augmented stories for reading comprehension, and a poetic metronome. …
