Nature Of Criticality, Structuring, And Phase Behavior Of Complex Fluids
(2009-03-04)
This thesis is mainly concerned with some important properties of complex fluids, and how these properties are influenced by structures in the nano/mesoscopic scale. Short-range assembly of the constituent molecules results ...
Gas Sensors - Micro-Heater Designs And Studies On Sensor Film Deposition
(2009-03-03)
Current gas sensor technology, although meeting the minimum requirements in many instances, suffers for a number of limitations. Hence, there is currently a considerable volume of research being undertaken at many ...
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 ...
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 ...
Gas Sensor-Studies On Sensor Film Deposition, ASIC Design And Testing
(2009-04-29)
The widespread use of Liquid Petroleum Gas (LPG) for cooking and as fuel for automobile vehicles requires fast and selective detection of LPG to precisely measure the leakage of gas for preventing the occurrence of accidental ...
Geometry Optimization Of Axially Symmetric Ion Traps
(2009-05-13)
This thesis presents numerical optimization of geometries of axially symmetric ion
trap mass analyzers. The motivation for this thesis is two fold. First is to demonstrate
how the automated scheme can be applied to achieve ...
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 ...
Development Of A Tin Oxide Based Thermoelectric Gas Sensor For Volatile Organic Compounds
(2009-09-22)
Today there is a great deal of interest in the development of gas sensors for applications like air pollution monitoring, indoor environment control, detection of harmful gases in mines etc. Based on different sensing ...
Study of Subharmonic Oscillations In Resonance Excitation Experiments In Nonlinear Paul Traps
(2009-07-08)
This thesis presents the results of studies on the problem of subharmonic oscillations in nonlinear Paul trap mass spectrometry. The objective of this thesis is to determine whether the subharmonic oscillations of ions in ...
Ultrasound Assisted Optical Elastography For Measurement Of Mechanical Properties Of Soft Tissue Mimicking Phantoms
(2009-03-03)
This work describes the development of an optical probe for measuring movement of tissue particles deep inside which are loaded by an ultrasound remote palpation device. The principle of the method is that ultrasound force ...
