Current research has shown that an increasing number of returning troops from deployments are being diagnosed with obstructed sleep apnea (OSA). OSA causes excessive daytime sleepiness that can endanger the readiness of Soldiers by impacting concentration, decision-making skills, personality change, hypertension, depression, headaches and has been shown to contribute to cardiovascular disease. A main factor for remediation of OSA is Soldier’s compliance with prescribed treatment plans. The two most popular methods for OSA treatment are continuous positive airway pressure (CPAP) and the Mandibular Advancing Device (MAD). Both of these devices have known compliance issues, which keep treatment of OSA to roughly 60 percent of those prescribed. We utilized a parameterized upper airway fluid structure–interaction (FSI) simulation to validate our hybrid OSA device (MAPPARD), which addressed the compliance issues found in typical OSA treatment devices. While being 25 percent less advanced than the MAD device and 50 percent less pressure than the CPAP device, our MAPPARD performed better than either current device, thus showing potential to improve Soldier treatment compliance. This study contributes to the ongoing exploration of the role of modeling and simulations for testing and evaluation of medical devices.

In early 2009, the Naval Postgraduate School (NPS) brought the 1152 core "hamming" Sun Microsystems blade system online. Concurrently, NPS procured RenderMan™ software from Pixar Animation Studios. In this presentation, Dr. Heferman and Mr. Weekley describe the hamming supercomputer, the Maya 3D modeling package with Pixar's RenderMan software - used by film studios to develop popular animated feature films such as "Ratatouille" and "Up" and in visual effects for movies like "Where the Wild Things Are" - and how NPS used them together to create realistic visualizations in a format suitable for projection on the NPS Sony 4K display and for ultra-high resolution streaming media over CENIC networks. Dr. Heferman and Mr. Weekley demonstrate how advances in Hollywood-style animation and post-production tools have benefited researchers at NPS who are working on scientific visualization and streaming media in support of the School's academic and research missions.

In this presentation, Jeff and Laurin discuss the technical challenges and successes, and the partnerships that emerged from a broad spectrum of entities to produce the live event at the CineGrid Workshop. In addition, they share the artistry of capturing and exhibiting an underwater habitat in 4K, and offer a unique opportunity rarely, if ever, seen to view undersea habitats through the lens of a two 4K cameras at 60 frames per second in ultra-high resolutions.
