An Efficient And Robust Computational Framework For Studying Lifetime And Information Capacity In Sensor Networks, Enrique J. Duarte-Melo, Mingyan Liu, Archan Misra

Research Collection School Of Computing and Information Systems

In this paper we investigate the expected lifetime and information capacity, defined as the maximum amount of data (bits) transferred before the first sensor node death due to energy depletion, of a data-gathering wireless sensor network. We develop a fluid-flow based computational framework that extends the existing approach, which requires precise knowledge of the layout/deployment of the network, i.e., exact sensor positions. Our method, on the other hand, views a specific network deployment as a particular instance (sample path) from an underlying distribution of sensor node layouts and sensor data rates. To compute the expected information capacity under this distribution-based …

Tailored Watermarking Schemes For Authentication Of Electronic Clinical Atlases, Feng Bao, Robert H. Deng, Beng-Chin Ooi, Yanjiang Yang

Research Collection School Of Computing and Information Systems

It is accepted that digital watermarking is quite relevant in medical imaging. However, due to the special nature of clinical practice, it is often required that watermarking not introduce irreversible distortions to medical images. The electronic clinical atlas has such a need of "lossless" watermarking. We present two tailored reversible watermarking schemes for the clinical atlas by exploiting its inherent characteristics. We have implemented the schemes and our experimental results look very promising.

E-Government Capabilities And Crisis Management: Lessons From Combating Sars In Singapore, Shan Ling Pan, Gary Pan, Paul R. Devadoss

Research Collection School Of Accountancy

The city-state of Singapore has been highly ranked for its e-government services. Over the past two decades, it has leveraged its IT infrastructure for economic development and transformed its public services. The SARS outbreak in 2004 turned into a national health crisis because it spread rapidly and the medical community had little knowledge of how to treat the new mutation of the corona virus. Yet, several Singaporean government agencies utilized the e-Government infrastructure and related resources to quickly bring the outbreak under control. In particular, the government?s IT infrastructure streamlined communications, information exchange, and data flow, and significantly eased collaboration …

Review Of Unity Of Knowledge And Action: Toward A Nonrepresentational Theory Of Knowledge, Sor-Hoon Tan

Research Collection School of Social Sciences

The title of this book is inspired by the Neo-Confucian scholar, Wang Yangming (1472-1529). However, the volume is not devoted solely to Wang Yangming's philosophy about the unity of knowledge and action. Wang is only one of several thinkers brought into this philosophical conversation and does not even receive the most attention (Richard Rorty has that honor). The conver- sation is interesting and occasionally illuminating, although one is not sure at the end whether it is moving toward one particular nonrepresentation theory of knowledge or whether the conversation partners who share an aversion to representational theories might disagree profoundly about …

Cultural Crossings Against Ethnocentric Currents: Toward A Confucian Ethics Of Communicative Virtues, Sor-Hoon Tan

Research Collection School of Social Sciences

Despite contemporary Confucianism's aspirations to be a world philosophy, there is an ethnocentric strand within the Confucian tradition, most glaringly exemplified in Han Yu's attacks on Buddhism. This paper re-assesses Confucian ethnocentrism in the context of contrary practices that indicate a more pragmatic attitude among Confucians toward cross-cultural interactions. It argues that while the ethnocentric tendency serves as constant reminder of the need for vigilance, and recognition of the difficulties of crossing cultural boundaries, there are nevertheless resources within Confucianism for constructing an ethics of communication that is urgently needed to deal with the moral problems of cultural pluralism. The …

Webarc: Website Archival Using A Structured Approach, Ee Peng Lim, Maria Marissa

Research Collection School Of Computing and Information Systems

Website archival refers to the task of monitoring and storing snapshots of website(s) for future retrieval and analysis. This task is particularly important for websites that have content changing over time with older information constantly overwritten by newer one. In this paper, we propose WEBARC as a set of software tools to allow users to construct a logical structure for a website to be archived. Classifiers are trained to. determine relevant web pages and their categories, and subsequently used in website downloading. The archival schedule can be specified and executed by a scheduler. A website viewer is also developed to …

Natural Forum And The Elusive Significance Of Jurisdiction Agreements, Tiong Min Yeo

Research Collection Yong Pung How School Of Law

The Singapore court's power to stay its proceedings by reason of its not being the appropriate forum the proceedings ought not to be continued is underpinned by the common law principle enunciated in The Spiliada that generally a trial should be heard in its natural forum. The Rainbow Joy adds significantly to Singapore law on forum non conveniens on two important points. First, it establishes that it is not necessary to show that the alternative forum abroad is constituted as a court of law. Secondly, the case establishes that whether there is a defense claim on the merits is an …

Georgia Technical College Administrators' Perceptions Of The Future Vocational And Academic Roles Of Georgia's Technical Colleges, Thomas Ennis Bragg

College of Graduate Studies: Theses & Dissertations

In 2000 the Georgia General Assembly passed House Bill 1187 giving the Georgia Department of Technical and Adult Education (DTAE) schools the right to change their names from technical institutes to technical colleges. This event could have led to a change in the type and method of delivery of course offerings at the technical colleges in Georgia. This study was designed to examine the technical college administrators' perceptions of the future vocational or academic roles of Georgia's technical colleges. A 21-question survey was designed to assess the administrators' perceptions of the future vocational and academic role of the 35 technical …

Integration Of Probabilistic Graphic Models For Decision Support, Jiang C., Poh K., Tze-Yun Leong

Research Collection School Of Computing and Information Systems

It is a frequently encountered problem that new knowledge arrived when making decisions in a dynamic world. Usually, domain experts cannot afford enough time and knowledge to effectively assess and combine both qualitative and quantitative information in these models. Existing approaches can solve only one of two tasks instead of both. We propose a four-step algorithm to integrate multiple probabilistic graphic models, which can effectively update existing models with newly acquired models. In this algorithm, the qualitative part of model integration is performed first, followed by the quantitative combination. We illustrate our method with an example of combining three models. …

The "New Judicial Federalism" Before Its Time: A Comprehensive Review Of Economic Substantive Due Process Under State Constitutional Law Since 1940 And The Reasons For Its Recent Decline, Anthony B. Sanders

American University Law Review

The coming of the New Deal may have spelled the end of the Lochner era in the federal courts, but in the state courts Lochner's doctrine of economic substantive due process lives on. Since the New Deal, courts in almost every state have rebuffed the United States Supreme Court and have interpreted their own state constitutions' due process clauses to provide substantive protections to economic liberties. This Article presents a comprehensive survey of state court use of economic substantive due process since the New Deal. It includes an enumeration of every instance since 1940 of a state court of highest …

An Analog Vlsi Implementation Of A Multi-Scale Spike Detection Algorithm For Extracellular Neural Recordings, Christy L. Rogers, John G. Harris, Jose C. Principe, Justin C. Sanchez

Electrical and Computer Engineering Faculty Research & Creative Works

This paper discusses a multi-scale neural spike detection algorithm for a low-power analog circuit implementation. The key idea is to implement wavelet decomposition and improve spike detection by independently controlling thresholds for each scale. Each thresholder scale is then combined to provide a single output indicating a spike occurrence. This spike detection algorithm shows promising results towards a robust, compact, and unsupervised low power analog spike detection circuit. A low power front-end spike detection circuit can be added to a neural amplifier and dramatically reduce the required data bandwidth for BMI applications. © 2005 IEEE.

Selected Georgia High School Principals' Perceptions Of Student Diversity, Ronald James Wiggins

College of Graduate Studies: Theses & Dissertations

This study was conducted to identify Georgia high school principals' perceptions of student diversity. The student demographics of many Georgia school districts and schools are changing rapidly, while some school districts and schools have not experienced much, if any, demographic change. As a result, it is important for principals to be aware of what other principals perceive as advantages and disadvantages, the types of policies/programs that impact principals in regard to student diversity as well as to be familiar with artifactual evidence that may represent an appreciation or awareness of student diversity. The data displayed in this study was gathered …

Current Parent Involvement Practices In Georgia Title I Schools As Reported By Title I District-Level School Administrators, Martha Massey Mcbride

College of Graduate Studies: Theses & Dissertations

The current parent involvement practices in Georgia Title I schools as reported by Title I district-level school administrators are described in this quantitative study. Data gathered describe strategies, means of communication, barriers, personnel, and staff development impacting parent involvement. The researcher found that, although districts employ a variety of research-based strategies to engage parents, only half of the surveyed strategies had been used with any degree of frequency. This is possibly attributable to the finding that almost two-thirds of the participants had five or fewer years Title I administration experience and that many districts had not provided teacher compensation or …

4-H Experiences Contributing To Leadership And Personal Development Of 4-H Alumni, Rama B. Radhakrishna, Megan Sinasky

Journal of Extension

The study reported here examined the contribution of 4-H experiences on leadership and personal development of Pennsylvania 4-H alumni. A total of 168 4-H alumni responded to a mail survey. Stepwise regression analysis identified six variables (challenges and responsibilities, benefits of 4-H participation, number of years in 4-H, animal science projects completed, usefulness and total number of 4-H projects completed) contributing to leadership and personal development. The variables explained 69.5% of the total variance. Pennsylvania 4-H alumni view their 4-H experience as very beneficial. The experiences they had in 4-H continue to influence them in later life.

Impact Of Labeling, Legislation, And Accommodations On The Academic Achievement Of African American Students With Learning Disabilities, Kimberly Suress Gaiters-Fields

College of Graduate Studies: Theses & Dissertations

During the last three decades, public schools have positively contemplated the concepts of mainstreaming, least restrictive environment and inclusion and have begun to serve more students with disabilities in K-12 general edcuation classes (Hicks-Coolick & Kurtz, 1996). There has been a corresponding increase in the number of students with disabilities who attend college and universities. However, at the postsecondary level, issues of educating students with disabilities are often different than those affecting K-12 education, and the instructional climate is much more challenging. Therefore, this trend calls for a more systematic method of assessing needed accommodations for diverse learning needs. The …

Reading Through Brown Eyes: Toward Developing A Culturally Congruent Reading Curriculum, Clara Taylor

College of Graduate Studies: Theses & Dissertations

This inquiry examined the reading motivations of African American middle grade males and investigated why some African American males are more successful academically in reading than others. This investigative pathway traveled through the possible interconnected barriers relative to reading achievement and reading motivation using the research strategy of critical narrative inquiry and the theoretical lens of critical race theory. Simultaneously, this qualitative analysis investigated racial/ethnic identity as it relates to background, popular culture, and learning styles as motivational factors for engaging African American males in reading and the learning process. African American, middle-grade males guided this path of exploration in …

Culture Of Obesity, Bridget Frugoli Melton

College of Graduate Studies: Theses & Dissertations

This dissertation sought to critically analyze the university environment by examining how the representation practices of corporations articulate with the growing obesity epidemic. For this study, existing data from one southeastern university was collected to describe the articulation between the university and obesity. The analysis examined the collected information and used the cultural studies concept of representation to expose the articulation between obesity and the university setting, including the three major theoretical works of Martin Nestle, Henry Giroux, Michel Foucault, and Paulo Freire. Physical fitness and dietary risk behaviors in students were described using the instrument of the 1995 National …

A Novel Method For Determination Of Dielectric Properties Of Materials Using A Combined Embedded Modulated Scattering And Near-Field Microwave Techniques-Part Ii: Dielectric Property Recalculation, R. Zoughi, Dana Hughes

Electrical and Computer Engineering Faculty Research & Creative Works

The use of combined embedded modulated scattering technique and near-field microwave nondestructive testing techniques is investigated as a novel method for evaluating the dielectric properties of a material. The forward formulation for determining the reflection coefficient at the aperture of a waveguide radiating into a dielectric half-space in which a PIN diode-loaded dipole (i.e., modulated scattering technique probe) is embedded was presented in Part I of this paper. Here, in Part II, the recalculation of the dielectric properties, using the results of the forward model, is presented along with some associated experimental results.

A Scalable Correlation Aware Aggregation Strategy For Wireless Sensor Networks, Yujie Zhu, Ramanuja Vedantham, Seung Jong Park, Raghupathy Sivakumar

Computer Science Faculty Research & Creative Works

Sensors-to-sink data in wireless sensor networks (WSNs) are typically correlated with each other. Exploiting such correlation when performing data aggregation can result in considerable improvements in the bandwidth and energy performance of WSNs. In order to exploit such correlation, we present a scalable and distributed correlation-aware aggregation structure that addresses the practical challenges in the context of aggregation in WSNs. Through simulations and analysis, we evaluate the performance of the proposed approach with centralized and distributed correlation aware and unaware structures.

A Novel Method For Determination Of Dielectric Properties Of Materials Using A Combined Embedded Modulated Scattering And Near-Field Microwave Techniques-Part I: Forward Model, Dana M. Hughes, R. Zoughi

Electrical and Computer Engineering Faculty Research & Creative Works

The use of combined embedded modulated scattering technique and near-field microwave nondestructive testing techniques is investigated as a novel method for evaluating the dielectric properties of a material. The forward formulation for determining the reflection coefficient at the aperture of a waveguide radiating into a dielectric half-space in which a PIN diode-loaded dipole (i.e., modulated scattering technique probe) is embedded is presented. This formulation is based upon calculating the near-field coupling between the waveguide and the dipole as a mutual impedance.

A Block Oriented Fingerprinting Scheme In Relational Database, Siyuan Liu, Shuhong Wang, Robert H. Deng, Weizhong Shao

Research Collection School Of Computing and Information Systems

The need for protecting rights over relational data is of ever increasing concern. There have recently been some pioneering works in this area. In this paper, we propose an effective fingerprinting scheme based on the idea of block method in the area of multimedia fingerprinting. The scheme ensures that certain bit positions of the data contain specific values. The bit positions are determined by the keys known only to the owner of the data and different buyers of the database have different bit positions and different specific values for those bit positions. The detection of the fingerprint can be completed …
