Optimization of Hazardous Waste Remediation Activities Using Life Cycle Assessment
(2011-04-28)The cleanup of hazardous waste sites promotes sustainability by removing toxins and other health threats left in the environment from previous unsustainable industrial practices. However, the remediation process consumes ... -
Optimization of Hidden Markov Model for Density Estimation in Breast Imaging
(2012)Breast cancer is the second leading cause of cancer-related death in women in the United States; it is fundamentally important to detect risks as accurately and as early as possible for prevention. As breast density often ... -
Optimization of Image Guided Radiation Therapy for Lung Cancer Using Limited-angle Projections
(2015)The developments of highly conformal and precise radiation therapy techniques promote the necessity of more accurate treatment target localization and tracking. On-board imaging techniques, especially the x-ray based ... -
OPTIMIZATION OF IMAGE GUIDED RADIATION THERAPY USING LIMITED ANGLE PROJECTIONS
(2009)Digital tomosynthesis (DTS) is a quasi-three-dimensional (3D) imaging technique which reconstructs images from a limited angle of cone-beam projections with shorter acquisition time, lower imaging dose, and less mechanical ... -
Optimization of RapidArc for Head-and-Neck Radiotherapy
(2011)<bold>Purpose:</bold> The goal of this planning study is to determine which sectors of the gantry rotation are most and least important in the treatment of head-and-neck carcinomas with Intensity Modulated Arc Therapy, and ... -
Optimization of Test and Design-for-Testability Solutions for Many-Core System-on-Chip Designs
(2014)With the continuous scaling of transistors to smaller dimensions, it has now become feasible to pack billions of transistors in a single chip. However, interconnect does not scale as well as transistors; hence a significant ... -
Optimization of the Aerodynamics of Small-scale Flapping Aircraft in Hover
(2008-06-27)Flapping flight is one of the most widespread mean of transportation. It is a complex unsteady aerodynamic problem that has been studied extensively in the past century. Nevertheless, by its complex nature, flapping flight ... -
Optimization Tools for the Design of Reconfigurable Digital Microfluidic Biochips
(2008-12-11)Microfluidics-based biochips combine electronics with biochemistry to open new application areas such as point-of-care medical diagnostics, on-chip DNA analysis, automated drug discovery and protein crystallization. Bioassays ... -
Optimization, Testing and Design-for-Testability of Flow-Based Microfluidic Biochips
(Jan 1 201)Flow-based microfluidic biochips constitute an emerging technology for the automation of biochemical procedures. Recent advances in fabrication techniques have enabled the development of these devices. Increasing integration ... -
Optimized approach to decision fusion of heterogeneous data for breast cancer diagnosis.
(Med Phys, 2006-08)As more diagnostic testing options become available to physicians, it becomes more difficult to combine various types of medical information together in order to optimize the overall diagnosis. To improve diagnostic ... -
Optimizing Conservation Benefits of Pelagic Marine Protected Areas: Assessing Alternative Timing of the Charleston Bump Time-Area Closure
(2017-04-28)The three-month Charleston Bump time-area closure was implemented in 2001 with the primary goal of reducing bycatch of juvenile swordfish in the U.S. Atlantic pelagic longline fishery. Due to this closure and other management ... -
Optimizing Database Algorithms for Random-Access Block Devices
(2015)The past decade has seen wide availability of solid-state drives (SSDs) in settings ranging from personal computing to enterprise storage. Their success over the hard disks is driven by performance considerations and cost ... -
Optimizing Nutrient and Timber Management for the Town of Butner, NC
(2011-04-29)The following report documents the findings of a client-focused group Master’s Project completed at the Nicholas School of the Environment at Duke University. The project’s purpose is to support the client’s goal to ... -
Optimizing Rainwater Harvesting Installation in Kashongi, Uganda
(2011-04-19)Community-based water supply systems like Institutional Rainwater Harvesting (IRWH) are promising solutions to water supply in rural areas like Uganda. However, IRWH tank systems have been unsustainable in the long-term ... -
Optimizing the Correction of Memory Errors
(2016)People are always at risk of making errors when they attempt to retrieve information from memory. An important question is how to create the optimal learning conditions so that, over time, the correct information is learned ... -
Optomechanical System Development of the AWARE Gigapixel Scale Camera
(2013)Electronic focal plane arrays (FPA) such as CMOS and CCD sensors have dramatically improved to the point that digital cameras have essentially phased out film (except in very niche applications such as hobby photography ... -
Order Beyond Borders: The Azerbaijani Triangle Across Iran, Turkey, and Russia
(2017)Turkey’s neo-Ottomanism, Iran’s Shi’a Crescent, and Russia’s neo-Eurasianism: together, they evince increasing transregionalism across West Asia. As states and societies interact beyond national borders, their interactions ... -
Organ Localization: Moving Toward Patient Specific Prospective Organ Dosimetry for CT
(2012)<bold>Purpose:</bold> Radiation doses from computed tomography (CT) examinations have come under public and governmental scrutiny because of several recent misadministrations of radiation across the country. Current CT ... -
