Coordinating Heterogeneous Web Services Through Handhelds Using Syd?S Wrapper Framework, Mohini Padhye Dec 2004

Coordinating Heterogeneous Web Services Through Handhelds Using Syd?S Wrapper Framework, Mohini Padhye

Computer Science Theses

Tying web services together to build large, distributed, collaborative applications has gathered noticeable momentum and a lot of research is being put in it. Along with composition of the web services, coordination is one key aspect that has been considered keenly. Many frameworks, languages and protocols have been proposed for web service composition and coordination. With the advancement in wireless technology and rapid deployment of mobile services, collaborative application development for small devices using such composed web services finds a new research area. Much less work has been done in the area of web service coordination for mobile environment. In …


A Volumetric Assessment Of Ancient Maya Architecture: A Gis Approach To Settlement Patterns, Kathryn Sorensen, Jeffrey Glover, Scott L. Fedick Jan 2004

A Volumetric Assessment Of Ancient Maya Architecture: A Gis Approach To Settlement Patterns, Kathryn Sorensen, Jeffrey Glover, Scott L. Fedick

Geosciences Faculty Publications

This paper will discuss the general applications of GIS technology to our research in the Yalahau Region of northern Quintana Roo, Mexico. In particular we will address the use of a volumetric analysis as a means of developing an architectural comparative framework at both the intrasite and regional scales. The comparative framework is a powerful tool that allows us to investigate and visualize the distribution of social power both within the site of T'isil and across the region. The direct relationship between social power and architectural volume is predicated on the assumption that actors who utilized the largest dwellings were …


Simulated Annealing Routing And Wavelength Lower Bound Estimation On Wdm Optical Multistage Networks, Ajay K. Katangur, Yi Pan, Martin D. Fraser Jan 2004

Simulated Annealing Routing And Wavelength Lower Bound Estimation On Wdm Optical Multistage Networks, Ajay K. Katangur, Yi Pan, Martin D. Fraser

Computer Science Faculty Publications

Multistage interconnection networks (MINs) are popular in switching and communication applications and have been used in telecommunication and parallel computing systems for many years. Crosstalk a major problem introduced by an optical MIN, is caused by coupling two signals within a switching element. We focus on an efficient solution to avoiding crosstalk by routing traffic through an N3N optical network to avoid coupling two signals within each switching element using wavelength-division multiplexing (WDM) and a time-division approach. Under the constraint of avoiding crosstalk, the interest is on realizing a permutation that uses the minimum number of passes for routing. This …


Mathematics As “Gate-Keeper” (?): Three Theoretical Perspectives That Aim Toward Empowering All Children With A Key To The Gate, David W. Stinson Jan 2004

Mathematics As “Gate-Keeper” (?): Three Theoretical Perspectives That Aim Toward Empowering All Children With A Key To The Gate, David W. Stinson

Middle-Secondary Education and Instructional Technology Faculty Publications

In this article, the author’s intent is to begin a conversation centered on the question: How might mathematics educators ensure that gatekeeping mathematics becomes an inclusive instrument for empowerment rather than an exclusive instrument for stratification? In the first part of the discussion, the author provides a historical perspective of the concept of “gatekeeper” in mathematics education. After substantiating mathematics as a gatekeeper, the author proceeds to provide a definition of empowering mathematics within a Freirian frame, and describes three theoretical perspectives of mathematics education that aim toward empowering all children with a key to the gate: the situated perspective, …


A Note On Empirical Likelihood Inference Of Residual Life Regression, Yichuan Zhao, Ying Qing Chen Jan 2004

A Note On Empirical Likelihood Inference Of Residual Life Regression, Yichuan Zhao, Ying Qing Chen

Mathematics and Statistics Faculty Publications

Mean residual life function, or life expectancy, is an important function to characterize distribution of residual life. The proportional mean residual life model by Oakes and Dasu (1990) is a regression tool to study the association between life expectancy and its associated covariates. Although semiparametric inference procedures have been proposed in the literature, the accuracy of such procedures may be low when the censoring proportion is relatively large. In this paper, the semiparametric inference procedures are studied with an empirical likelihood ratio method. An empirical likelihood confidence region is constructed for the regression parameters. The proposed method is further compared …
