In spacecraft engineering, the time and money involved in satellite construction is largely spent on design and integration of custom hardware and software. These efforts are duplicated for nearly every satellite with little to no reuse between spacecraft. There is a huge potential for cost savings in removing the duplication of work. However, there is a lack of standardization in the spaceflight community, causing soaring costs and delayed schedules as each component of a spacecraft is individually designed and custom built.
The Air Force Research Laboratory (AFRL) has developed the Space Plug-and-Play Architecture (SPA) to address this problem. SPA provides …
A Novel And Effective Short Track Speed Skating Tracking System, Yuxuan Wang
A Novel And Effective Short Track Speed Skating Tracking System, Yuxuan Wang
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Short track speed skating lends itself to intense competitions with a strong visual impact. Thus, the sport has become increasingly popular. In fact, in 1992, short track speed skating became an official Winter Olympic sport with four events, and four more events were added in 2002. Because of the sport’s growing popularity, there is a high demand from both coaches and TV broadcasters for a means of automatically gathering competition data such as trajectories, velocities, and 2D reconstruction animation. We call this vision-based sports video analysis.
In competitive short track speed skating, multiple skaters skate together on an ice track …
Test Case Generation Using Combinatorial Based Coverage For Rich Web Applications, Chad Maughan
Test Case Generation Using Combinatorial Based Coverage For Rich Web Applications, Chad Maughan

Web applications are increasingly moving business and processing logic from the server to the browser. Traditional, multiple-page request/response applications are quickly being replaced by single-page applications where complex application logic is downloaded on the initial page load and data is then subsequently fetched asynchronously via the browser's native XMLHttpRequest (XHR) object.
These new generation web applications are called Rich Web Applications (RWA). Frameworks such as the Google Web Toolkit (GWT), and JavaScript model-view-controller (MVC) frameworks such as Backbone.js are facilitating this move. With this migration, testing frameworks need to follow the logic by moving analysis and test generation from the …
Combinatorial-Based Prioritization For User-Session-Based Test Suites, Schuyler Manchester
Combinatorial-Based Prioritization For User-Session-Based Test Suites, Schuyler Manchester
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Software defects caused by inadequate software testing can cost billions of dollars. Further, web application defects can be costly due to the fact that most web applications handle constant user interaction. However, software testing is often under time and budget constraints. By improving the time efficiency of software testing, many of the costs associated with defects can be saved.
Current methods for web application testing can take too long to generate test suites. In addition, studies have shown that user-session-based test suites often find faults missed by other testing techniques. This project addresses this problem by utilizing existing user sessions …
A Localized Geometric-Distortion Resilient Digital Watermarking Scheme Using Two Kinds Of Complementary Feature Points, Jiyuan Wang
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
More and more digital images are being distributed over the Internet to an evergrowing number of people for sharing, studying, or other purposes. However, most of those digital products are exposed without any protection, and such information can be easily transferred, copied, and tampered without authorization simply by using readily available digital multimedia editing software. Digital watermarking techniques have been developed as a tool to discriminate whether the original content of digital media is tampered or not. A digital watermark is embedded on digital images as an invisible message and is used to demonstrate the proof by the owner.

Cell migration is central for many fundamental biological processes and development of multi-cellular organisms. The failure of cells to migrate or migration of cells to inappropriate locations during embryo development can result in life threatening consequences such as brain malfunctions. In adults, cell migration plays an important role in wound healing and immune responses. Failure in these processes can have dramatic medical implications and can lead to vascular diseases and tumor formation. Therefore, studying cell migration is critical to helping prevent and cure diseases.
Cell migration is usually studied by observing cells photographed through a microscope at regular time intervals. …
Planning, Acting, And Learning In Incomplete Domains, Christopher H. Weber
Planning, Acting, And Learning In Incomplete Domains, Christopher H. Weber
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The engineering of complete planning domain descriptions is often very costly because of human error or lack of domain knowledge. Learning complete domain descriptions is also very challenging because many features are irrelevant to achieving the goals and data may be scarce. Given incomplete knowledge of their actions, agents can ignore the incompleteness, plan around it, ask questions of a domain expert, or learn through trial and error.
Our agent Goalie learns about the preconditions and effects of its incompletely-specified actions by monitoring the environment state. In conjunction with the plan failure explanations generated by its planner DeFault, Goalie diagnoses …

Massively multiplayer games make up a large and growing segment of the computer game industry. One of the best known examples of these games is World of Warcraft, developed and published by Activision Blizzard. World of Warcraft boasts a subscriber base of over eleven million active subscribers, earning an estimated $1 billion dollars in 2010.
Some of the core issues for companies that publish these games are the cost of the computers, Internet bandwidth usage, and supporting technical staff. These costs easily reach hundreds of thousands of dollars each month, and in the case of World of Warcraft, millions of …

Java Api-Aware Code Generation Engine: A Prototype, Chandra Sekhar Vijyapurpu
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Software reuse enhances a programmer's productivity and reduces programming errors. Improving software reuse through libraries and frameworks is a vast problem area. This thesis offers an approach to solve two sub-problems within the problem area - to identify the right library components, and to offer code snippets that use the components correctly. The Java API-Aware Code Generation Engine, or JAGE for short, is a prototype system that demonstrates the feasibility of generating semantically valid code snippets consisting of method calls to classes in the J2SDK library.
Developers often search for sample code snippets that describe how to use the …
Planning In Incomplete Domains, Jared William Robertson
Planning In Incomplete Domains, Jared William Robertson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Automated planning in computer science consists of finding a sequence of actions leading from an initial state to a goal state. People who have expert knowledge of the specific problem domain work with experts in automated planning to define the domain states and actions. This knowledge engineering required to create complete and correct domain descriptions for planning problems is often very costly and difficult. Our goal with incomplete planning is to allow people to program domains without the need for planning experts.
Throughout the process of instruction of intelligent systems, teachers can often leave out whole procedures and aspects of …
