MULTI-MODAL BEHAVIOR AND CLUSTERING IN DYNAMICAL SYSTEM WITH APPLICATIONS TO WIND FARMS
(2009)
he objective of this research is to develop a comprehensive model identification approach for complex multi-modal systems based on spectral theory for nonreversible Markov process that entails (i)model reduction techniques ...
IV-VI LEAD SALT MID-INFRARED LIGHT EMITTING DEVICE DESIGN, FABRICATION AND CHARACTERIZATIONIV-VI LEAD SALT MID-INFRARED LIGHT EMITTING DEVICE DESIGN, FABRICATION AND CHARACTERIZATION
(2009)
The research detailed by this dissertation has demonstrated the design, fabrication, and characterization of lead salt semiconductor mid-infrared light emitting devices. A scrupulous theoretical model has been described ...
EXPLORING THE CAPABILITIES OF THE AGILE BEAM PHASED ARRAY WEATHER RADAR
(2009)
Weather radar researchers have long been eager to exploit the capabilities of phased array antennas, but high cost and technical complexity have postponed their widespread use in radar meteorology. With the aging of the ...
TOWARD A MORE CLARIFIED DETECTIVE QUANTUM EFFICIENCY METHODOLOGY: STUDY OF THE DQE THEORY AND APPLICATIONS
(2009)
Detective quantum efficiency (DQE) is widely accepted as the golden rule to objectively evaluate the performance of x-ray imaging systems. It provides a comprehensive characterization of an x-ray imaging system, because ...
IDENTIFICATION OF EXTREMELY LOW FREQUENCY ERROR COMPONENTS IN THE GLOBAL POSITIONING SYSTEM (GPS)/WIDE AREA AUGMENTATION SYSTEM (WAAS) POSITION SOLUTION
(2009)
The Wide Area Augmentation System (WAAS) was intended to "augment" the basic Global Positioning System (GPS) navigation service to the necessary level to support precision approach operations equivalent to the Instrument ...
SPATIAL FILTERING OF CLUTTER USING PHASED ARRAY RADARS FOR OBSERVATIONS OF THE WEATHER
(2009)
Phased array radars are attractive for weather surveillance primarily because of their capacity for extremely rapid scanning through electronic steering. When combined with the recently developed beam multiplexing technique, ...
Feasibility of a Cognitive Extension to Existing 802.11b Wireless Devices
(2009)
Cognitive radio presents a means of altering the communication method of a wireless device based on channel conditions and the intended receiving device. However, the design of such a radio is very complicated as it must ...

OBSERVATIONAL STUDY OF RAIN MICROPHYSICS AND RAIN RETRIEVAL USING POLARIMETRIC RADAR DATA
(2009)
Accurate quantitative precipitation estimation (QPE) and quantitative precipitation forecasts (QPF) require accurate microphysical parameterization/modeling of the precipitation. This study presents the modeling of rain ...
OPTOELECTRONIC THREE-DIMENSIONAL TRACKING SYSTEM FOR COLLISION RISK MODEL
(2009)
The purpose of this dissertation is to develop a new, novel and low cost three-dimensional tracking system that can produce a Time and Space Position Information (TSPI) database for developing an FAA Collision Risk Model ...
