ALERT: This system is being upgraded on Tuesday December 12. It will not be available
for use for several hours that day while the upgrade is in progress. Deposits to DukeSpace
will be disabled on Monday December 11, so no new items are to be added to the repository
while the upgrade is in progress. Everything should be back to normal by the end of
day, December 12.

A study of the aeroelastic behavior of flat plates and membranes with mixed boundary conditions in axial subsonic flow
(2011)In support of the noise reduction targets for future generations of transport aircraft, as set forth by NASA, the fundamental aeroelastic behavior of trailing edge flap technology was explored. Using a plate structural model ... -
Adaptive stereotactic body radiation therapy planning for lung cancer.
(Int J Radiat Oncol Biol Phys, 2013-09-01)PURPOSE: To investigate the dosimetric effects of adaptive planning on lung stereotactic body radiation therapy (SBRT). METHODS AND MATERIALS: Forty of 66 consecutive lung SBRT patients were selected for a retrospective ... -
Attenuation of inflammatory events in human intervertebral disc cells with a tumor necrosis factor antagonist.
(2010)STUDY DESIGN: The inflammatory responses of primary human intervertebral disc (IVD) cells to tumor necrosis factor α (TNF-α) and an antagonist were evaluated in vitro. OBJECTIVE: To investigate an ability for soluble TNF ... -
Characterization of Image Quality for 3D Scatter Corrected Breast CT Images.
(2012)The goal of this study was to characterize the image quality of our dedicated, quasi-monochromatic spectrum, cone beam breast imaging system under scatter corrected and non-scatter corrected conditions for a variety of breast ... -
Comparative performance of multiview stereoscopic and mammographic display modalities for breast lesion detection.
(2010)PURPOSE: Mammography is known to be one of the most difficult radiographic exams to interpret. Mammography has important limitations, including the superposition of normal tissue that can obscure a mass, chance alignment ... -
Deposition of silver nanoparticles in geochemically heterogeneous porous media: predicting affinity from surface composition analysis.
(2011)The transport of uncoated silver nanoparticles (AgNPs) in a porous medium composed of silica glass beads modified with a partial coverage of iron oxide (hematite) was studied and compared to that in a porous medium composed ... -
Efficient selection of disambiguating actions for stereo vision
(2010)In many domains that involve the use of sensors, such as robotics or sensor networks, there are opportunities to use some form of active sensing to disambiguate data from noisy or unreliable sensors. These disambiguating ... -
Mechanical constraints enhance electrical energy densities of soft dielectrics
(2012)In this thesis, a new method---mechanical constraint to increase the energy density of soft dielectrics is described. Electromechanical breakdown is one of the main factors limiting the energy density and it is induced by ... -
Musculoskeletal symptoms among female garment factory workers in Sri Lanka.
(2011)OBJECTIVES: To assess the prevalence of musculoskeletal symptoms and their association with sociodemographic risk factors among female garment factory workers in Sri Lanka. METHODS: 1058 randomly selected female garment ... -
Non-parametric approximate linear programming for MDPs
(2012)One of the most difficult tasks in value function based methods for learning in Markov Decision Processes is finding an approximation architecture that is expressive enough to capture the important structure in the value ... -
Plate-specific gain map correction for the improvement of detective quantum efficiency in computed radiography.
(2010)The purpose of this work is to improve the NPS, and thus DQE, of CR images by correcting for pixel-to-pixel gain variations specific to each plate. Ten high-exposure open field images were taken with an RQA5 spectrum, with ... -
Prostate Bed Motion During Post-Prostatectomy Radiotherapy

Stream segregation on a single electrode as a function of pulse rate in cochlear implant listeners.
(2010)While cochlear implants usually provide a high level of speech recognition in quiet, speech recognition in noise and music appreciation remain challenging. In response to these issues, several studies have proposed increasing ... -
Vehicular MIMO SAR Imaging in Multipath Environments
(2011)Current synthetic aperture radars (SAR) are most effective in simple, open terrains where direct-path propagation can be assumed. For ground-vehicle based SAR from a moving platform, however, strong multipath scattering ...
