Stereotactic Localization And Targeting Accuracy For Experimental Proton Radiosurgery, Yin Chen
Stereotactic Localization And Targeting Accuracy For Experimental Proton Radiosurgery, Yin Chen
Theses Digitization Project
The purpose of this study was to improve an existing experimental proton radiosurgery system at Loma Linda University Medical Center to reach sub-millimeter accuracy before proton radiosurgery with narrow beams can be used in a clinical trial. Protons, different from photons (i.e., x-rays or gamma rays), are charged with particles that slow down in matter and release a burst of energy near the end of their range (maximum depth of penetration), which is called the Bragg peak, named after the physicist William Henry Bragg who discovered it in 1903. Photon beams deliver most doses over a large area near the …
Alternative Hull Detection Techniques For Preprocessing In Proton Computed Tomography Reconstruction, Blake Edward Schultze
Alternative Hull Detection Techniques For Preprocessing In Proton Computed Tomography Reconstruction, Blake Edward Schultze
Theses Digitization Project
The purpose of this study was to develop computationally efficient hull detection techniques appropriate for image reconstruction using sparse matrices. The hull detection techniques investigated were space carving (SC), modified space carving (MSC), and space modeling (SM) and these were compared to the cone-beam version of filtered back projection (FBP) algorithm in terms of their computation time and the quality of the object hull they produced.
Fiducial-Free Alignment Verification Techniques For Intracranial Radiosurgery, Kenneth Matthew Williams
Fiducial-Free Alignment Verification Techniques For Intracranial Radiosurgery, Kenneth Matthew Williams
Theses Digitization Project
This thesis serves as the basis for a method using image registration to automate patient alignment in an effort to eliminate the dependency on the fiducial markers as well as improve the accuracy efficiency of the alignment process. Proton beams are an external beam modality of radiation therapy that can be used effectively for radiosurgical applications due to the dosimetry advantage of the Bragg peak. The Bragg peak is a phenomenon exploited by proton beam therapy to concentrate the effect of the beams on the tumor while minimizing damage to critical structures and other health tissues within the patient.
Developing Focused Auditing Tools: A Practical Framework For Creating Formalized Multi-Level Security Policy Specifications, Barbara Ann Brough
Developing Focused Auditing Tools: A Practical Framework For Creating Formalized Multi-Level Security Policy Specifications, Barbara Ann Brough
Theses Digitization Project
The purpose of this study is that formalized policy specifications and focused penetration testing are needed to effectively audit any information system. Designing and maintaining the security system information is the primary duty of the cyber security professional. In today's world, nearly all government agencies manage some form of financial, defense, national security, and/or privacy information security policies. It is also necessary in this environment that agencies are accountable for auditing the security systems that protect this information.

Asynchronous Cellular Automata, Kelechi Chidi Anuforo
Theses Digitization Project
This study will investigate floating-point asynchronous cellular automata models implemented on Field-Programmable Gate Array (FPGA). It includes single grid and random schedules for individual cells. Cellular automata (CA) are basic representations of calculations that show interesting elaborate responses.
3d Face Animation With Opengl Es: An Android Application, Ihab Mohamad Zbib
3d Face Animation With Opengl Es: An Android Application, Ihab Mohamad Zbib
Theses Digitization Project
Mobile applications have become ubiquitious with the increase in the popularity and computational power of mobile devices. They can now support rich multimedia user interactions. This project consists of the design and implementaiton of an Android application that renders and animates a three-dimensional model of a human head. The test is synthesized using an Android Text-to-Speech (TTS) engine. The application successfully implements a novel solution for the animated speech synchronization and opens the door for further work in the field of interactive animation. The project can be extended to become an interface for virtual remote communication or animated text messaging.
