A Dynamic Insertion Approach For Multi-Dimensional Data Using Index Structures, Yong Shi Jan 2009

A Dynamic Insertion Approach For Multi-Dimensional Data Using Index Structures, Yong Shi

Faculty Articles

Nowadays large volumes of data with high dimensionality are being generated in many fields. Most existing indexing techniques degrade rapidly when dimensionality goes higher. A large amount of data sets are time related, and the existence of the obsolete data in the data sets may seriously degrade the data processing. In our previous work[7], we proposed ClusterTree+, a new indexing approach representing clusters generated by any existing clustering approach. It is a hierarchy of clusters and subclusters which incorporates the cluster representation into the index structure to achieve effective and efficient retrieval. It also has features from the …

Physical And Link Layer Implications In Vehicle Ad Hoc Networks, Ghassan Mohammed Taha Abdalla Jan 2009

Physical And Link Layer Implications In Vehicle Ad Hoc Networks, Ghassan Mohammed Taha Abdalla

School of Engineering, Computing and Mathematics Theses

Vehicle Ad hoc Networks (V ANET) have been proposed to provide safety on the road and deliver road traffic information and route guidance to drivers along with commercial applications. However the challenges facing V ANET are numerous. Nodes move at high speeds, road side units and basestations are scarce, the topology is constrained by the road geometry and changes rapidly, and the number of nodes peaks suddenly in traffic jams. In this thesis we investigate the physical and link layers of V ANET and propose methods to achieve high data rates and high throughput. For the physical layer, we examine …

The Manufacture And Testing Of Perforated Composite Acoustic Panels, Robert Blackburn Jan 2009

The Manufacture And Testing Of Perforated Composite Acoustic Panels, Robert Blackburn

School of Engineering, Computing and Mathematics Theses

The recent expansion of civil aviation has been accompanied by significant growth in the use of advanced composite structures with carbon fibre reinforced epoxy often the material of choice in many structures. Composite structures have a long history in engine nacelles, where an optimised design can both fulfil structural requirements and simultaneously provide an acoustic liner for sound attenuation. The "traditional process" involves the drilling of high-density multiple holes with the twin consequences of extended production times and machining waste. Elimination of this perforation process is an attractive target in a commercial environment. Structural performance could be improved by retaining …

Heller High Water? The Future Of Originalism, Jamal Greene Jan 2009

Heller High Water? The Future Of Originalism, Jamal Greene

Faculty Scholarship

Has originalism won? It's easy to think so, judging from some of the reaction to the Supreme Court's recent decision in District of Columbia v. Heller. The Heller Court held that the District of Columbia could neither ban possession of handguns nor require that all other firearms be either unloaded and disassembled or guarded by a trigger lock. In finding for the first time in the Court's history that a gun control law violated the Second Amendment, Justice Scalia's opinion for the 5-4 majority appeared to be a sterling exemplar of originalism, the method of constitutional interpretation that he …

Civil Liability And Mandatory Disclosure, Merritt B. Fox Jan 2009

Civil Liability And Mandatory Disclosure, Merritt B. Fox

Faculty Scholarship

This Article explores the efficient design of civil liability for mandatory securities disclosure violations by established issuers. An issuer not publicly offering securities at the time of a violation should have no liability. Its annual filings should be signed by an external certifier – an investment bank or other well-capitalized entity with financial expertise. If the filing contains a material misstatement and the certifier fails to do due diligence, the certifier should face measured liability. Officers and directors should face similar liability, capped relative to their compensation but with no indemnification or insurance allowed. Damages should be payable to the …

On Capturing The Possible Significance Of Institutional Design And Ethos, Peter L. Strauss Jan 2009

On Capturing The Possible Significance Of Institutional Design And Ethos, Peter L. Strauss

Faculty Scholarship

At a recent conference, a new judge from one of the federal courts of appeal – for the United States, the front line in judicial control of administrative action-made a plea to the lawyers in attendance. Please, he urged, in briefing and arguing cases reviewing agency actions, help us judges to understand their broader contexts. So often, he complained, the briefs and arguments are limited to the particular small issues of the case. We get little sense of the broad context in which it arises – the agency responsibilities in their largest sense, the institutional issues that may be at …

Contracting For Innovation: Vertical Disintegration And Interfirm Collaboration, Ronald J. Gilson, Charles F. Sabel, Robert E. Scott Jan 2009

Contracting For Innovation: Vertical Disintegration And Interfirm Collaboration, Ronald J. Gilson, Charles F. Sabel, Robert E. Scott

Faculty Scholarship

Rapidly innovating industries are not behaving the way theory expects. Conventional industrial organization theory predicts that, when parties in a supply chain have to make transaction-specific investments, the risk of opportunism will drive them away from contracts and toward vertical integration. Despite the conventional theory, however, contemporary practice is moving in the other direction. Instead of vertical integration, we observe vertical disintegration in a significant number of industries, as producers recognize that they cannot themselves maintain cutting-edge technology in every field required for the success of their products. In doing this, the parties are developing forms of contracting beyond the …

Mechanistic Evaluation Of Rubblized Pcc Pavements, Yigong Ji Jan 2009

Mechanistic Evaluation Of Rubblized Pcc Pavements, Yigong Ji

JTRP Technical Reports

This report presents a mechanistic approach and procedures for determining layer coefficients to characterize the in-situ behaviors of rubblized pavements. This procedure was developed based on the 1993 AASHTO Pavement Design Guide utilizing Falling Weight Deflectometer (FWD) testing and in-place simulation using back-calculation layer modulus. In order to evaluate the rubblized pavement systematically, twelve constructed pavement sections were extensively tested by FWD annually after construction. The FWD data was processed using the proposed mechanistic procedure. In addition, statistical analysis was conducted to compare the pavement structure parameters each year, including layer coefficient and in-situ resilient modulus using Analysis of Variance …

Performance Related Specifications (Prs) For Concrete Pavements In Indiana, Volume 1: Executive Summary, Cole Graveen, Eric Max Falker, Micah Beaver, Narayanan Neithalath, W. Jason Weiss, J. Olek, Tommy Edward Nantung, Victor Lee Gallivan

JTRP Technical Reports

Performance-Related Specifications (PRS) are specifications that base pavement acceptance and pay adjustment on the projected performance and predicted life-cycle cost (LCC) for a specific pavement. PRS relate measurable quality characteristics with pavement performance through computer simulations that incorporate physical distress models. Previously, work at ERES consultants by Darter and co-workers developed prototype PRS for jointed plain portland cement concrete pavements (PCC) through Federal Highway Administration (FHWA) through a series of research projects. However, before this research program began, pavements have not been constructed using these specifications. This report describes the Indiana Department of Transportation’s (INDOT) experience with developing and implementing …

Relating Material Properties To Exposure Conditions For Predicting Service Life In Concrete Bridge Decks In Indiana, Vinit Barde, Aleksandra Radlinska, Menashi Cohen, W. Jason Weiss

JTRP Technical Reports

Bridges in the US are deteriorating at an alarming rate. It has been estimated that transportation agencies across the US invest more than 5 billion dollars on concrete bridge repair and renovation annually. To meet the needs of transportation industry, high performance concrete (HPC) has been developed for the construction of bridges. However, to date, the link between material properties and field performance is not completely established. Goodspeed et al. [1996] defined the performance of concrete using four material parameters that describe durability and four material parameters that describe mechanical properties. It should be noted however that material properties alone …

Saw-Cutting Guidelines For Concrete Pavements: Examining The Requirements For Time And Depth Of Saw-Cutting, Kambiz Raoufi, Tony Their, W. Jason Weiss, Jan Olek, Tommy E. Nantung Jan 2009

Saw-Cutting Guidelines For Concrete Pavements: Examining The Requirements For Time And Depth Of Saw-Cutting, Kambiz Raoufi, Tony Their, W. Jason Weiss, Jan Olek, Tommy E. Nantung

JTRP Technical Reports

Joints are placed in Portland cement concrete pavements (PCCP) to control random cracking. These joints provide a weakened plane that enables a crack to form in a controlled manner, relieving residual stresses that develop when thermal, hygral, or hydration movements are resisted by sub grade and adjoining pavement. While the concept of creating a weakened plane through saw-cutting is straightforward, determining the time and depth of the saw-cut has proven to be complicated. The goal of this project was to reduce the risk for joint raveling and random cracking. Specifically, this project has focused on: developing a procedure for determining …

Synthesis Of Best Practices In Transportation Security, Volume I: Vulnerability Assessment, Haritha Reddy Venna, Jon D. Fricker

JTRP Technical Reports

Part I of the research focused on developing a methodology to identify and evaluate the most critical and vulnerable INDOT assets. This method aims at obtaining an index that reflects the vulnerability and criticality of an asset on the basis of multiple performance criteria. This methodology was tested on the seven INDOT districts. Because not all the factors that influence the vulnerability do have same weight, the analytical hierarchical process is used to obtain the weights for the criteria. Countermeasures are suggested as a part of the research to reduce the vulnerability of a given asset based on its relevant …

The Perspective Of School Personnel In A Georgia School District Concerning The Recruitment Of Minority Teachers, Shyla D. Ridley Jan 2009

The Perspective Of School Personnel In A Georgia School District Concerning The Recruitment Of Minority Teachers, Shyla D. Ridley

College of Graduate Studies: Theses & Dissertations

Recruiting and attracting minorities into the teaching profession is difficult. Given the competitiveness of the current job market and the heavy emphasis on standardized testing for all teacher candidates, the difficulties of attracting quality minority teachers are becoming more challenging. The lack of a racially and culturally diverse teaching staff remains a major issue in education nationally and locally, especially since projections indicate that the representation of minority teachers is declining while the number of minority students is increasing. This need for more minority teachers is even more critical in urban public schools characterized by large percentages of minority students …

Efficient Estimation Of Copula-Based Semiparametric Markov Models, Xiaohong Chen, Wei Biao Wu, Yanping Yi Jan 2009

Efficient Estimation Of Copula-Based Semiparametric Markov Models, Xiaohong Chen, Wei Biao Wu, Yanping Yi

Cowles Foundation Discussion Papers

This paper considers efficient estimation of copula-based semiparametric strictly stationary Markov models. These models are characterized by nonparametric invariant (one-dimensional marginal) distributions and parametric bivariate copula functions; where the copulas capture temporal dependence and tail dependence of the processes. The Markov processes generated via tail dependent copulas may look highly persistent and are useful for financial and economic applications. We first show that Markov processes generated via Clayton, Gumbel and Student’s t $ copulas and their survival copulas are all geometrically ergodic. We then propose a sieve maximum likelihood estimation (MLE) for the copula parameter, the invariant distribution and the …

Is There Such A Thing As Postmodern Copyright?, Peter Jaszi Jan 2009

Is There Such A Thing As Postmodern Copyright?, Peter Jaszi

Scholarly Articles in Law Reviews & Journals

Back in 1992, artist/entrepreneur Jeff Koons suffered a humiliating setback when the United States Court of Appeals for the Second Circuit repudiated the suggestion that his reuse of objects from public culture might constitute a "fair use" defense to a copyright infringement claim. Fourteen years later, in a case that again involved a photographer's claim of copyright infringement, Koons triumphed in the same judicial forum. What had changed? This Article explores, in particular, one among a variety of alternative explanations: Koons may have caught the very leading edge of a profound wave of change in the social and cultural conceptualization …
