Opportunistic Random Access in CSMA/CA-Based Wireless Networks
(2013-10-18)
IEEE 802.11 MAC based CSMA/CA (Carrier Sense Multiple Access with Collision
Avoidance) is the most widely used protocol in wireless networks. In CSMA/CA, every
node listens to the shared wireless medium and transmits ...
The opportunity for alternative reinforcement shortens bout length in BALB/c C57BL/6 mice
(2008-08-15)
A recent mathematical model has been suggested to partition response rate into two independent components that are estimated through a log survivor analysis of inter-response times. One component is thought to tap motivational ...
The Opposition Court of Henry, Prince of Wales, in the Reign of James I, 1610-1612
(2010-04-08)
Henry Frederick Stuart, eldest son of James VI and I and Anne of Denmark, died at the age of eighteen after only two years as Prince of Wales. In his short life he developed a large following and served as the focal point ...
Optical Spectroscopy of Wide-band-gap Semiconductors: Raman and Photoluminescence of Gallium Nitride, Zinc Oxide and Their Nanostructures
(2006-12-15)

Optical Waveguide Sensor based on Gratings and Metamaterials for Refractive Index Sensing
(2020-07-14)
Optical waveguide sensors based on gratings and metamaterials for refractive index (RI) sensing are introduced in this Ph.D. dissertation. A waveguide is a structure which can guide light based on total internal reflection. ...
Optimal egg incubation temperature, and the effects of diet on growth of hatchling Eastern Indigo snakes (Drymarchon couperi) during a captive head-start program
(2014-05-12)
Optimal husbandry techniques are desirable for any headstart program, but frequently are unknown for rare species. In this thesis I determine the optimal incubation temperature and optimal diet diversity for eastern indigo ...
Optimal Observation Selection in Magnetic Resonance Spectroscopic Imaging
(2011-03-29)
Magnetic resonance spectroscopic imaging (MRSI) is a completely non-invasive
method for obtaining quantitative information regarding biochemical parameters [1].
It shows great promise for use in basic physiological ...
Optimization and economics of small-scale, on-farm biodiesel production using oilseed crops and waste vegetable oil
(2011-05-25)
Recent concerns over unpredictable fuel prices and desire to reduce farm input costs have warranted producer interest in growing alternative crops for the production of biofuels such as biodiesel. Ideally, biodiesel could ...
Optimization and Investigation of SO2 Adsorption Process for Solid Oxide Fuel Cell Cathode Protection
(2017-04-25)
Gas-phase contaminant removal is a critical process for power supply systems (e.g. fuel cells and gas turbines). Because of high-energy efficiency, low emissions, and fuel flexibility, Solid Oxide Fuel Cells (SOFCs) are ...
Optimization Approaches for a Dubins Vehicle in Coverage Planning Problem and Traveling Salesman Problems
