A Confidence-Prioritization Approach To Data Processing In Noisy Data Sets And Resulting Estimation Models For Predicting Streamflow Diel Signals In The Pacific Northwest, Nathaniel Lee Gustafson

Theses and Dissertations

Streams in small watersheds are often known to exhibit diel fluctuations, in which streamflow oscillates on a 24-hour cycle. Streamflow diel fluctuations, which we investigate in this study, are an informative indicator of environmental processes. However, in Environmental Data sets, as well as many others, there is a range of noise associated with individual data points. Some points are extracted under relatively clear and defined conditions, while others may include a range of known or unknown confounding factors, which may decrease those points' validity. These points may or may not remain useful for training, depending on how much uncertainty they …

Integrating "Code Smells" Detection With Refactoring Tool Support, Kwankamol Nongpong

Theses and Dissertations

Refactoring is a form of program transformation which preserves the semantics of the program. Refactoring frameworks for object-oriented programs were first introduced in 1992 by William Opdyke. Few people apply refactoring in mainstream software development because it is time consuming and error-prone if done by hand. Since then, many refactoring tools have been developed but most of them do not have the capability of analyzing the program code and suggesting which and where refactorings should be applied. Previous work discusses many ways to detect refactoring candidates but such approaches are applied to a separate module. This work proposes an approach …

A Configuration Management System For Software Product Lines, Cheng Thao

Theses and Dissertations

Software product line engineering (SPLE) is a methodology for developing a family of software products in a particular domain by systematic reuse of shared code in order to improve product quality and reduce development time and cost. Currently, there are no software configuration management (SCM) tools that support software product line evolution. Conventional SCM tools are designed to support single product development.

The use of conventional SCM tools forces developers to treat a software product line as a single software project by introducing new programming language constructs or using conditional compilation. We propose a research conguration management prototype called Molhado …

A Physiological Signal Processing System For Optimal Engagement And Attention Detection., Ashwin Belle

Theses and Dissertations

In today’s high paced, hi-tech and high stress environment, with extended work hours, long to-do lists and neglected personal health, sleep deprivation has become common in modern culture. Coupled with these factors is the inherent repetitious and tedious nature of certain occupations and daily routines, which all add up to an undesirable fluctuation in individuals’ cognitive attention and capacity. Given certain critical professions, a momentary or prolonged lapse in attention level can be catastrophic and sometimes deadly. This research proposes to develop a real-time monitoring system which uses fundamental physiological signals such as the Electrocardiograph (ECG), to analyze and predict …

Detection Likelihood Maps For Wilderness Search And Rescue: Assisting Search By Utilizing Searcher Gps Track Logs, Michael Thomas Roscheck

Theses and Dissertations

Every year there are numerous cases of individuals becoming lost in remote wilderness environments. Principles of search theory have become a foundation for developing more efficient and successful search and rescue methods. Measurements can be taken that describe how easily a search object is to detect. These estimates allow the calculation of the probability of detection—the probability that an object would have been detected if in the area. This value only provides information about the search area as a whole; it does not provide details about which portions were searched more thoroughly than others. Ground searchers often carry portable …

Technique And Cue Selection For Graphical Presentation Of Generic Hyperdimensional Data, Lee Mont Howard

Theses and Dissertations

The process of visualizing n-D data presents the user with four problems: finding a hyperdimensional graphics package capable of rendering n-D data, finding a suitable presentation technique supported by the package that allows insight to be gained, using the provided user interface to interact with the presentation technique to explore the information in the data, and finding a way to share the information gained with others. Many graphics packages have been written to solve the first problem. However, existing packages do not sufficiently solve the other three problems. A hyperdimensional graphics package that sufficiently solves all these problems simplifies the …

Analysis And Design Tools For Structured Feedback Systems, Anurag Rai

Theses and Dissertations

The White-Hat Bot: A Novel Botnet Defense Strategy, Tyrone C. Gubler

Theses and Dissertations

Botnets are a threat to computer systems and users around the world. Botmasters can range from annoying spam email propagators to nefarious criminals. These criminals attempt to take down networks or web servers through distributed denial-of-service attacks, to steal corporate secrets, or to launder money from individuals or corporations. As the number and severity of successful botnet attacks rise, computer security experts need to develop better early-detection and removal techniques to protect computer networks and individual computer users from these very real threats. I will define botnets and describe some of their common purposes and current uses. Next, I will …

Resource Provisioning In Large-Scale Self-Organizing Distributed Systems, M. Brent Reynolds

Theses and Dissertations

This dissertation researches the mathematical translation of resource provisioning policy into mathematical terms and parameters to solve the on-line service placement problem. A norm called the Provisioning Norm is introduced. Theorems presented in the work show the Provisioning Norm utility function and greedy, random, local search effectively and efficiently solve the on-line problem. Caching of placements is shown to reduce the cost of change but does not improve response time performance. The use of feedback control theory is shown to be effective at significantly improving performance but increases the cost of change. The theoretical results are verified using a decentralized, …

Enhancing Trust In The Smart Grid By Applying A Modified Exponentially Weighted Averages Algorithm, Andrew T. Kasperek

Theses and Dissertations

The main contribution of this thesis is the development and application of a modified Exponentially Weighted Moving Algorithm (EWMA) algorithm, and its ability to robustly function in the face varying numbers of bad (malicious or malfunctioning) Special Protection System (SPS) nodes. Simulation results support the use of the proposed modified EWMA reputation based trust module in SPSs within a smart grid environment. This modification results in the ability to easily maintain the system above the minimum acceptable frequency of 58.8 Hz at the 95% confidence interval, when challenged with test cases containing 5, 10 and 15 bad node test cases …

Decentralized Riemannian Particle Filtering With Applications To Multi-Agent Localization, Martin J. Eilders

Theses and Dissertations

The primary focus of this research is to develop consistent nonlinear decentralized particle filtering approaches to the problem of multiple agent localization. A key aspect in our development is the use of Riemannian geometry to exploit the inherently non-Euclidean characteristics that are typical when considering multiple agent localization scenarios. A decentralized formulation is considered due to the practical advantages it provides over centralized fusion architectures. Inspiration is taken from the relatively new field of information geometry and the more established research field of computer vision. Differential geometric tools such as manifolds, geodesics, tangent spaces, exponential, and logarithmic mappings are used …

Vulnerability Analysis Of The Player Command And Control Protocol, John T. Hagen

Theses and Dissertations

The Player project is an open-source effort providing a control interface specification and software framework for abstracting robot hardware. This research presents five exploits that compromise vulnerabilities in Player's command and control protocol. The attacks exploit weaknesses in the ARP, IP, TCP and Player protocols to compromise the confidentially, integrity, and availability of communication between a Player client and server. The attacks assume a laptop is connected in promiscuous mode to the same Ethernet hub as the client and server in order to sniff all network traffic between them. This work also demonstrates that Internet Protocol Security (IPsec) is capable …

Forensic Memory Analysis For Apple Os X, Andrew F. Hay

Authorship Is Continuous: Detecting Plagiarism In Student Code Assignments With Version Control, Ian Mathias Koss

Theses and Dissertations

In academia, the conflict between plagiarist and instructor is reaching a crescendo. The increasing availability of source material available from the Internet, either for free or for hire, is met by the increasing sophistication of tools that help with the detection of these activities. These plagiarism detection tools work by comparing sets of documents to identify similar passages of text, but this approach has some inherent limitations. Chief among these is the single source problem. If a student hires someone to write a term paper for him or her, clearly plagiarism has taken place. However, there is no second copy …
