Synchronization Of Lecture Videos And Electronic Slides By Video Text Analysis, Feng Wang, Chong-Wah Ngo, Ting-Chuen Pong

Research Collection School Of Computing and Information Systems

An essential goal of structuring lecture videos captured in live presentation is to provide a synchronized view of video clips and electronic slides. This paper presents an automatic approach to match video clips and slides based on the analysis of text embedded in lecture videos. We describe a method to reconstruct high-resolution video texts from multiple keyframes for robust OCRrecognition. A two-stage matching algorithm based on the title and content similarity measures between video clips and slides is also proposed.

Aa Flexible And Scalable Authentication Scheme For Jpeg 2000 Image Codestreams, Cheng Peng, Robert H. Deng, Yongdong Wu, Weizhong Shao

Research Collection School Of Computing and Information Systems

JPEG2000 is an emerging standard for still image compression and is becoming the solution of choice for many digital imaging fields and applications. An important aspect of JPEG2000 is its "compress once, decompress many ways" property [1], i. e., it allows extraction of various sub-images (e.g., images with various resolutions, pixel fidelities, tiles and components) all from a single compressed image codestream. In this paper, we present a flexible and scalable authentication scheme for JPEG2000 images based on the Merkle hash tree and digital signature. Our scheme is fully compatible with JPEG2000 and possesses a "sign once, verify many ways" …

Sulfide Mineralization In Deep-Water Marine Sediments Related To Methane Transport, Methane Consumption, And Methane Gas Hydrates, Matthew K. Thompson, Walter S. Borowski, Charles K. Paull, William Ussler Iii

EKU Faculty and Staff Scholarship

Patterns of sulfide sulfur concentration and sulfur isotopic composition (d³⁴S) are perhaps related to upward methane transport, especially in sediments underlain by methane gas hydrate deposits. Increased methane delivery augments the affect of anaerobic methane oxidation (AMO) occurring at the sulfate-methane interface (SMI). Sulfate and methane co-consumption results in production of dissolved sulfide at the interface that is eventually sequestered within sulfide minerals (elemental sulfur, iron monosulfide, pyrite).

We examine the sediments of two piston cores collected over the Blake Ridge gas hydrate deposits (offshore southeastern North America) by extracting total sedimentary sulfide using chromium reduction. We use …

Updating Bridge Reliability Based On Bridge Management Systems Visual Inspection Results, Allen C. Estes, Dan M. Frangopol

Architectural Engineering

Bridge management systems have become increasingly sophisticated over the past decade and provide valuable information about the structural condition of all bridges in the national database. At the same time, reliability methods have gained increasing prominence and are used to forecast life-cycle performance over many decades of structural life. Such reliability analyses need to be updated based on the results of inspections. Specifically targeted nondestructive evaluations are the preferred solution, but are not always available for every bridge. This paper examines how the visual inspection data provided from bridge management systems already in place can be used to update the …

Issue Definition And The Opinion-Policy Link: Public Preferences And Health Care Spending In The Us And Uk, Stuart N. Soroka, Elvin T. Lim

Research Collection School of Social Sciences

This article explores the extent to which yearly changes in health spending reflect yearly changes in public preferences. Time series modelling suggests that health care spending is remarkably more responsive to yearly changes in public opinion in the US than in the UK.A content analysis of party manifestos suggests the significant role of ‘issue definition’ in accounting for this difference. Health care issues in the US have more often been viewed as problems of expenditure, while UK policy-makers have tended to focus on efficiency. Results suggest that the responsiveness of health care expenditures to public preferences in the US and …

Content-Aware Authentication Of Motion Jpeg2000 Stream In Lossy Networks, Yongdong Wu, Robert H. Deng

Research Collection School Of Computing and Information Systems

Stream authentication schemes (SAS) aim to achieve effective authentication of multicast streams over lossy networks. Almost all the existing SASs is designed for stream data integrity protection only. In this paper, we argue that content integrity protection is more important than data integrity to human users. We present a content-aware SAS in motion JPEG2000 streaming. In our scheme, a chunk of JPEG2000 codestreams is encapsulated into a block of packets using multiple description coding (MDC). Our MDC exploits the inherent structure of motion JPEG2000 codestreams and is used to preserve the semanteme/content of the stream over lossy networks. To achieve …

The Situation: An Introduction To The Situational Character, Critical Realism, Power Economics, And Deep Capture, Jon Hanson, David Yosifon

Faculty Publications

Throughout most of this introductory Article, we will focus our arguments primarily on economics and law and economics. We believe, however, that the implications of our inquiry extend far beyond those domains. The tendencies we hope to elucidate find their origins in the human animal, not in any particular legal theoretic perspective. It happens that these tendencies are especially prominent in law and economics, currently the dominant theoretical paradigm for creating and analyzing legal policy. But the relevance of our thesis is not confined to one approach , or even to legal-political questions. All humans are more or less implicated, …

Precipitation Monitoring At Yucca Mountain From 10/01/2000 Through 06/30/2003, Amanda Brandt, Klaus J. Stetzenbach, Amy J. Smiecinski

Publications (YM)

This report presents precipitation data collected using tipping bucket rain gauges in the vicinity of Yucca Mountain from October 1, 2000 to June 30, 2003. Operation of the tipping bucket precipitation monitoring network was assumed by the Harry Reid Center for Environmental Studies at University of Nevada, Las Vegas in March 2001. Previously, it had been operated by the U.S. Geological Survey. The precipitation monitoring network consists of 17 tipping bucket gauges at various locations in the vicinity of Yucca Mountain. During the 2001 water year, rainfall averaged 6.16 inches. The following 2002 water year was much drier averaging 1.11 …

Formation And Growth Of Intermetallics Around Metallic Particles In Eutectic Sn-Ag Solder, J. G. Lee, Katherine C. Chen, K. N. Subrmanian

Materials Engineering

Incorporation of metallic particulate reinforcements in eutectic Sn-Ag solder results in the formation of intermetallic compounds (IMCs) along particulate/ solder interfaces with different morphologies. For instance, “sunflower” and “blocky faceted” IMC shapes have been observed around Ni particle reinforcements incorporated in the eutectic Sn-Ag solder matrix. The time and temperature above solder liquidus during the heating stage of the reflow process has been found to play a significant role in determining the IMC morphology in these Ni particulate-reinforced solders. Similar studies were carried out with Cu and Ag particulate reinforcements using the same solder matrix. The amount of heat input …

The Maintenance Of Conservative Physical Laws Within Data Assimilation Systems, G.A. Jacobs, H.E. Ngodock

Faculty Publications

In many data assimilation applications, adding an error to represent forcing to certain dynamical equations may be physically unrealistic. Four-dimensional variational methods assume either an error in the dynamical equations of motion (weak constraint) or no error (strong constraint). The weak-constraint methodology proposes the errors to represent uncertainties in either forcing of the dynamical equations or parameterizations of dynamics. Dynamical equations that represent conservation of quantities (mass, entropy, momentum, etc.) may be cast in an analytical or control volume flux form containing minimal errors. The largest errors arise in determining the fluxes through control volume surfaces. Application of forcing errors …

A Study Of Enso Prediction Using A Hybrid Coupled Model And The Adjoint Method For Data Assimilation, Eli Galanti, Eli Tziperman, Matthew Harrison, Anthony Rosati, Ziv Sirkes

Faculty Publications

An experimental ENSO prediction system is presented, based on an ocean general circulation model (GCM) coupled to a statistical atmosphere and the adjoint method of 4D variational data assimilation. The adjoint method is used to initialize the coupled model, and predictions are performed for the period 1980-99. The coupled model is also initialized using two simpler assimilation techniques: forcing the ocean model with observed sea surface temperature and surface fluxes, and a 3D variational data assimilation (3DVAR) method, similar to that used by the National Centers for Environmental Prediction (NCEP) for operational ENSO prediction. The prediction skill of the coupled …

The Effects Of Anterior Cruciate Ligament Reconstruction On Tibial Rotation During Pivoting After Descending Stairs, Stavros Ristanis, Giannis Giakas, Christos D. Papageorgiou, Constantina O. Moraiti, Nikolaos Stergiou, Anastasios D. Georgoulis

Journal Articles

Recent in vitro research suggests that ACL reconstruction does not restore tibial rotation. This study investigated rotational knee joint stability in vivo during a combined descending and pivoting movement that applies a high rotational load to the knee joint. We studied 20 ACL reconstructed patients (bone–patellar tendon–bone graft) and 15 matched controls with a six-camera optoelectronic system performing the examined movement. In the control group the results showed no significant differences in the amount of tibial rotation between the two sides. No significant differences were also found between the contralateral intact leg of the ACL group and the healthy control. …

Oci-Based Group Communication Support In Corba, Dongman Lee, Dukyun Nam, Hee Yong Youn, Chansu Yu

Electrical and Computer Engineering Faculty Publications

Group communication is a useful mechanism guaranteeing consistency among replicated objects. The existing approaches do not allow transparent plug-in of group communication protocols into CORBA. They either require modification of CORBA or OS, or provide no room for incorporating group communication transport protocols into CORBA. We thus propose a generic group communication framework that allows transparent plug-in of various group communication protocols with no modification of existing CORBA. We extend the open communications interface (OCI) to support interoperability, reusability of existing group communication, and independency on ORB and OS. We also define the group communication inter-ORB protocol (GCIOP) as a …

Kalman Filtering For Fuzzy Discrete Time Dynamic Systems, Daniel J. Simon

Electrical and Computer Engineering Faculty Publications

This paper uses Kalman filter theory to design a state estimator for noisy discrete time Takagi–Sugeno (T–S) fuzzy models. One local filter is designed for each local linear model using standard Kalman filter theory. Steady state solutions can be found for each of the local filters. Then a linear combination of the local filters is used to derive a global filter. The local filters are time-invariant, which greatly reduces the computational complexity of the global filter. The global filter is shown to be unbiased and (under certain conditions) stable. In addition, under the approximation of uncorrelatedness among the local models, …

Sec Enforcement Heuristics: An Empirical Inquiry, Randall Thomas, James D. Cox

Vanderbilt Law School Faculty Publications

This Article examines the overlap between SEC securities enforcement actions and private securities fraud class actions. We begin with an overview of data concerning all SEC enforcement actions from 1997 to 2002. We find that the volume of SEC enforcement proceedings is relatively modest. We next examine the scope of the recently enacted "Fair Fund" provision that authorizes the SEC to designate civil penalties it recovers from defendants to benefit defrauded private investors. We conclude that this provision offers only limited potential relief for private investors. We complete this Part of the Article with an analysis of the serious resource …

It's Time To Make The Administrative Procedure Act Administrative, Edward L. Rubin

Vanderbilt Law School Faculty Publications

The Administrative Procedure Act (APA) has been out of date from the day it was written because it fails to address the administrative character of the modern state. The APA imposes procedural requirements on agency rulemaking and adjudication, two activities that are singled out because they resemble legislation and judicial decision making in the premodern state. The requirements for adjudication are based on the procedural rules that govern courts; the requirements for rulemaking would be based on the procedural rules that govern legislatures, but because very few such rules exist, they are also based on the rules that govern courts. …

Prospect Theory, Risk Preference, And The Law, Chris Guthrie

Vanderbilt Law School Faculty Publications

To understand how people behave in an uncertain world - and to make viable recommendations about how the law should try to shape that behavior - legal scholars must employ a model or theory of decision making. Only with an understanding of how people are likely to respond to legal rules can legal scholars, judges, legislators, and regulators craft rules that are likely to encourage desirable behavior and discourage undesirable behavior. Rather than rely on rational choice theory, behavioral law and economics scholars (or legal decision theorists) have turned to Daniel Kahneman and Amos Tversky's "prospect theory" to inform their …

Lowering The Filed Tariff Shield: Judicial Enforcement For A Deregulatory Era, Jim A. Rossi

Vanderbilt Law School Faculty Publications

The filed tariff doctrine, fashioned by courts to protect consumers from rate discrimination, has strayed from its origins. Instead of protecting consumers, the doctrine has evolved into a shield for regulated firms against common law and antitrust claims that reinforce market norms. In the ideal world, Congress would expand the jurisdiction of regulatory agencies to allow them to penalize private misconduct. However, since that has not always happened, the filed tariff doctrine has encouraged private firms to expend resources in using the regulator as a strategy to immunize conduct from antitrust and common law antitrust claims. This Article assesses how …

2001 Michigan Hospital Cqi/Tqm Study, Colleen L. Croxall

Wayne State University Dissertations

In recent years, there has been significant interest in the application of total quality management/continuous quality improvement (TQM/CQI) within health care organizations. The health care industry, in its quest to improve outcomes with fewer resources, began to look at CQI/TQM as a possible solution. To date, the most comprehensive and enthusiastic response to efforts to improve quality while containing or lowering costs is reflected in hospitals' commitment to continuous quality improvement/total quality management (CQI/TQM). The health care industry, particularly hospitals, has embraced the concepts of CQI/TQM with the belief that adoption will lead to an improvement in both the quality …

Nursing Faculty Publications

The purpose of this article is to describe the process of creating a faculty development program for online instruction. Both educational and technological issues are discussed. Factors that will facilitate and barriers that will impede the implementation of online courses are included. Many faculty concerns regarding online courses relate to the issues of quality and student learning. Faculty development activities are directed to ensure that courses are developed using sound educational theory and principles. Online courses are first about student learning; using the technology is second. Thus, faculty development programs must be two-pronged, involving instructional design and technology. It is …

Effects Of Salts On Crystallization Kinetics And Rheological Behavior Of Concentrated , -Trehalose Solutions, Marina Cerdeira, M. C. Puppo, Silvana Martini, M. L. Herrera

Nutrition, Dietetics, and Food Sciences Faculty Publications

The effect of addition of CaCl2 2H2O and MgCl2 6H2O on crystallization kinetics and the rheological behavior of a 70% trehalose solution was studied by polarized light microscopy and dynamic oscillatory rheometry. Salts caused a delay on nucleation with induction times for crystallization longer for Mg2+ than for Ca2+. Divalent cations were incorporated into crystals, changing the growth of certain faces preferentially, which resulted in changes in morphology. Addition of CaCl2 2H2O in a high salt/trehalose molar ratio dramatically increased complex modulus (G*), indicating a stronger viscoelastic behavior. A gel-like structure was formed when Ca2+ was added to trehalose solution. …

Newspaper Coverage Of Animal Abuse, Lara Jasmine Imbrock

Student Work

The abuse of animals is an important social issue. Animals play a vital role in society, serving as companions and service animals for people. A qualitative content analysis was conducted to evaluate Midwest newspaper coverage of animal abuse in 1993, 1998, and 2002. The theories of social construction of reality, agenda setting, and priming were used to examine the effects of media coverage of animal abuse. Results showed that animal abuse has received increased coverage over the years.

The Effects Of Self-Efficacy And Locus Of Control On The Sexual Behaviors Of College Females, Michelle Noah

Student Work

This research examined the relationship between self-efficacy, locus of control, and sexual behaviors among college females. The research null hypotheses suggest that; 1) There is no correlation between self-efficacy and responsible sexual behaviors, and 2) There is no correlation between locus of control and responsible sexual behaviors. Questionnaire data were collected from 109 undergraduate females at a Midwestern University. The sample was primarily Caucasian (89%), heterosexual (96.3%), and single (73.4%) with a mean age of 23 years. An investigator designed questionnaire, adapted in part, from the Rotter Internal-External Locus of Control Scale (RIELC), The General Self-Efficacy Scale (GSE), and a …
