All-Fiber Sensing Techniques For Structural Health Monitoring And Other Applications
(2010-03-02)In this thesis, we explore the four aspects of fiber Bragg grating sensors: mathematical modeling of Fiber Bragg Grating response/spectral characteristics, fabrication using phase mask, application and interrogation. ... -
Denoising And Inpainting Of Images : A Transform Domain Based Approach
(2009-05-25)Many scientific data sets are contaminated by noise, either because of data acquisition process, or because of naturally occurring phenomena. A first step in analyzing such data sets is denoising, i.e., removing additive ... -
Design And Development Of A Liquid Scintillator Based System For Failed Fuel Detection And Locating System In Nuclear Reactors
(2009-07-02)Failed fuel refers to the breach in the fuel-clad of an irradiated fuel assembly in a nuclear reactor. Neutron detection or gamma detection is commonly used in Failed Fuel Detection and Locating (FFDL) system to monitor ... -

Investigations On Topological Thresholds In Metal Doped Ternary Telluride Glasses
(2009-06-16)The ability to tune the properties over a wide range of values by changing the additives, composition, etc., has made chalcogenide glassy semiconductors, most interesting from both fundamental physics as well as technology ... -
A New Method To Determine Optimal Time-Delays Between Switching Of Digital VLSI Circuits To Minimize Power Supply Noise
(2010-06-01)Power supply noise, which is the variation in the supply voltage across the on-die supply terminals of VLSI circuits, is a serious performance degrader in digital circuits and mixed analog-digital circuits. In digital VLSI ... -
Property Modulation Of Zinc Oxide Through Doping
(2009-04-24)Semi conductors are of technological importance and attracted many of the re-searchers. ZnO belongs to the family of II-VI semiconductors and has material properties well suitable to UV light emitters, varistors, Schottky ... -
Small Angle Measurement Using Optical Caustics From Hollow Cylinders - Few Investingations
(2009-09-15)‘Optical Caustics’ represent some of the most visually striking patterns of the light in nature.They occur when light rays from a source, such as the sun, get refracted, or reflected by curved media so as to bend and alter ... -
Studies On The Electrical Properties Of Titanium Dioxide Thin Film Dielectrics For Microelectronic Applications
(2009-05-06)The scaling down of Complementary Metal Oxide Semiconductor (CMOS) transistors requires replacement of conventional silicon dioxide layer with higher dielectric constant (K) material for gate dielectric. In order to reduce ...
