The Design And Implementation Of An Over-The-Top Cloud-Based Vertical Handover Decision Service For Heterogeneous Wireless Networks, Adam Hodges
All Theses
The widespread availability of heterogeneous wireless networks (hetnets) presents a resource allocation challenge to network operators and administrators. Overlapping network coverage should be utilized to its fullest extent, providing users with a fair share of bandwidth while maximizing the efficient use of the operator's resources. Currently, network selection occurs locally at the mobile device and does not take into account factors such as the state of other networks that might be available in the device's location. The local decision made by the device can often result in underutilization of network resources and a degraded user experience. This type of selfish …

Developing A Predictive Model Of Heart Wall Motion In Fluoroscopic Images, Christopher Hawkins
Developing A Predictive Model Of Heart Wall Motion In Fluoroscopic Images, Christopher Hawkins
All Theses
Image guided surgery (IGS) is an integral part of minimally invasive surgery. IGS combines pre- and perioperative images acquired from different imaging modalities to give the surgeon a more complete view of the internal organs. These modalities include computed tomography, magnetic resonance imaging, and fluoroscopy, to name a few. Fluoroscopy is also known as video x-ray and is becoming increasingly popular in procedures around the heart. Unfortunately, this increase in fluoroscopy use also brings an increase in exposure to ionizing radiation for the patient and the surgeon. This radiation can lead to increased cancer risk and a number of other …

Long-Term Multi-Dimensional Interactive Time-Lapse Photography Using Microsoft Kinect, Daniel Mccoy
All Theses
In this thesis, a method is presented for the capture and interactive presentation of long-term multi-dimensional time-lapse photography. Time-lapse capture is commonly used for the observation based study of relatively long term phenomena such as plant growth and weather patterns. In terms of filmic devices, the visual time compression effect is complementary to slow motion and is nearly as prevalent. In this project, commonly available camera and computer equipment is used to capture images autonomously with minimal system supervision. A set of images is established, using long term, short interval continuous capture at a fixed position. Results are presented demonstrating …
Design Of A Custom Software Application To Monitor And Communicate Cnc Machining Process Information To Aid In Chatter Identification, Valerie Pezzullo
Design Of A Custom Software Application To Monitor And Communicate Cnc Machining Process Information To Aid In Chatter Identification, Valerie Pezzullo
All Theses
In any manufacturing environment, it is important to be able to monitor the Computer Numerical Control (CNC) machining process so that high quality parts can be produced in the least amount of time in order to be profitable. This involves acquiring the proper parameters needed from the machine's controller, which can prove to be difficult with proprietary machine tools that tend to limit access to the internal data collected by the controller. This closed approach to controller design also means that many technological advances that have recently become prevalent in society are not being adopted in the manufacturing industry, preventing …

White Noise And Newer Media: The Prophetic Impact Of Jack's Avatars, Caleb Milligan
White Noise And Newer Media: The Prophetic Impact Of Jack's Avatars, Caleb Milligan
All Theses
In this paper, I analyze Don DeLillo's White Noise through a contemporary techno-literate approach that utilizes Internet and game studies to better understand its protagonist, Jack Gladney, and to reevaluate the novel's critical legacy. Jack is not a modernist living in a postmodern world, as critics like Tom LeClair, John Duvall, and Leonard Wilcox have claimed for the many years since the publication of this novel. Lacking the authentic consistency for such a title, he is instead a postmodern human simulacrum sampling different character types to avoid his lack of discernable self. In each role he plays, however, he is …
An Automated Build System For Articulated Characters, James Sledge
An Automated Build System For Articulated Characters, James Sledge
All Theses
Rigging is the process of designing and implementing the manipulation architecture for an animated three-dimensional character. Rigs that give the animator the most control tend to be the most difficult to set up and maintain. Due to the linear nature of some elements of rigging, the more complicated a rig, the more time-intensive--and therefore more expensive--to achieve a high quality rig. A solution to complex rig iterability is to automate as much of the process as possible. The topic of this thesis is a framework for modular rigging automation, with a focus on quick and efficient rig iteration. A rigger …

Efficient Control Of Assets In A Modern Production Pipeline, Timothy Curtis
All Theses
Managing large collections of assets created in today's CG productions is no easy task. This thesis examines basic production hierarchies and identifies problems that arise without proper workflow and asset control. The possibility of hundreds of assets being created in several workflows each week creates the potential for extraordinary time waste and user error without a system to track and manage the files being produced. It is becoming increasingly necessary to utilize methods during production that enforce naming and storage standards to prevent catastrophic data loss. This thesis presents an implementation of a customized database used to track all of …

Corl8: A System For Analyzing Diagnostic Measures In Wireless Sensor Networks, Loren Klingman
All Theses
Due to an increasing demand to monitor the physical world, researchers are deploying wireless sensor networks more than ever before. These networks comprise a large number of sensors integrated with small, low-power wireless transceivers used to transmit data to a central processing and storage location. These devices are often deployed in harsh, volatile locations, which increases their failure rate and decreases the rate at which packets can be successfully transmitted. Existing sensor debugging tools, such as Sympathy and EmStar, rely on add-in network protocols to report status information, and to collectively diagnose network problems. Some protocols rely on a central …
