Discretization and Learning of Bayesian Networks using Stochastic Search, with Application to Base Realignment and Closure (BRAC)

Hoyt, Pamela J. (2008-07-01)

The need for automated Bayesian Network (BN) construction from data has increased for a variety of reasons. Elicitation of networks from experts can be time consuming and expensive. With large, complex problems, construction ...
An Assessment Methodology for Predicting the Success of Technological Enterprises

Abbas, Abeer Al-Hassan (2008-07-15)

Every year thousands of students and budding entrepreneurs participate in technical business plan competitions in over 44 institutions in the US alone. The stakes are high: over $4 million dollars of prize money and ...
Analysis of the Relationship between Partially Dynamic Bayesian Network Architecture and Inference Algorithm Effectiveness

Cannon, Stephen J. (2008-07-24)

This thesis examines the relationship between the architecture of partially dynamic Bayesian networks and the effectiveness of various inference algorithms using these Bayesian networks. The algorithms studied were the ...
Weighted Clustering Ensembles

Al-Razgan, Muna Saleh (2008-08-06)

Clustering is a popular approach to exploratory data analysis and mining. How- ever, clustering faces difficult challenges due to its ill-posed nature. First, it is well known that off-the-shelf clustering methods may ...
Acoustic modeshape inversion using deep water ambient noise measurements

AlMuhanna, Khalid A. (2008-08-07)

Ocean acoustic tomography is a powerful method that uses sound to study ocean properties such as temperature, which is directly related to sound speed in water. This thesis focuses on using ambient noise to infer the ...
Instant Learning For Crisis Response

Suydam, Martin (2008-08-07)

Important to effective use of graphic portrayals of data and information is the science of communicating effectively with symbols. In general, today’s practice of icon design is more art than true science. While ...
Minimizing the Pain in Air Transportation: Analysis of Performance and Equity in Ground Delay Programs

Manley, Bengi (2008-08-13)

The air transportation system is a significant "engine" of the U.S. economy providing rapid, safe, secure, affordable transportation over large geographic distances. Growth in passenger and cargo transportation demand ...
Role of Web Services for Globally Distributed Information Retrieval Systems in a Grid Environment (Implementation and Performance Analysis of a Prototype)

Chilappagari, Sairam (2008-08-13)

Information retrieval is an important aspect of any data storage system. As the data storage capability increases there will always be need for an information retrieval (IR) system, which caters to the growing needs of ...
Query Consolidation: Interpreting Queries Sent to Independent Heterogenous Databases

Acar, Aybar C. (2008-08-14)

This dissertation introduces the problem of query consolidation, which seeks to interpret a set of disparate queries submitted to independent databases with a single “global” query. The problem has multiple applications, ...
Symmetric Multiprocessing Virtualization

Southern, Gabriel (2008-08-14)

The reemergence of system virtualization, and the introduction of the single-chip multiprocessor, are two technologies that are altering the landscape of modern general-purpose computing architecture. System virtualization ...
Testing Calculation Engines Using Input Space Partitioning and Automation

Alluri, Chandra M. (2008-08-15)

This thesis proposes a solution to test calculation engines in financial services applications such as banking, mortgage, insurance, and trading. Calculation engines form the heart of financial applications, as the results ...
Measurement of angular spread of signals in SWellEx-96 using multitaper array processing

Wheelock, Richard J. (2008-08-21)

Detection and bearing estimation in shallow water is difficult due to multipath. As array aperture increases, angular resolution increases and observation of multipath becomes more likely. The SWellEx-96 experiment ...
On the Characterization and Analysis of System of Systems Architectures

Liles, Stewart Whitfield (2008-09-02)

A goal of an agile organization is the ability to adapt its structure to constantly changing operating environments so it can provide the multiple capabilities that enable mission accomplishment. A challenge for the ...
A Multi-channel Defense Against Communication Denial-of-Service Attacks in Wireless Networks

Alnifie, Ghada Matooq (2008-12-11)

In this dissertation, we focus on the security and reliability of wireless sensor networks (WSNs). We specifically address attacks which target the availability of the wireless communication medium. Due to their unattended ...
Study of reliability mechanisms and their interaction in nanoscale CMOSFETs

Mishra, Rahul (2008-12-12)

This dissertation is a study of device reliability issues and their interactions in nano-scale bulk and SOI CMOSFETs. As integrated circuits (ICs) become smaller and faster, susceptibility of devices to damage increases ...
Optical Characterization of Wide-band gap Bulk crystals and Epitaxial layers

Gowda, Madhu H. (2008-12-12)

This dissertation describes the non-destructive optical characterization of undoped/doped GaN and SiC bulk crystals and epitaxial layers. These materials have applications for optoelectronic devices that are operational ...
Architectures and Models for Administration of User-Role Assignment in Role Based Access Control

Bhamidipati, Venkata Ramana Murthy (2008-12-18)

In role based access control systems (RBAC) permissions are associated with roles, and users are made members of appropriate roles thereby acquiring the roles’ permissions. This greatly simplifies management of permissions. ...
Secure Data Aggregation in Wireless Sensor Networks

Roy, Sankardas (2008-12-19)

Wireless sensor networks have proved to be useful in several applications, such as environment monitoring and perimeter surveillance. In a large sensor network, in-network data aggregation (i.e., combining partial results ...
Virtual Human Anatomy and Surgery System

Liu, Yanling (2009-01-29)

Historically, medical students have practiced on cadavers to learn human anatomy, as have physicians wanting to brush up on their knowledge. However, because of storage cost and limited availability of cadavers, practice ...
Multi-channel Hardware/Software Codesign on a Software Radio Platform

Bales, Jason M. (2009-01-29)

Software Defined Radios (SDRs) are growing in popularity in our increasingly multi- standard wireless world. As a result, platforms have been developed to provide powerful and flexible SDR implementations. These platforms ...
