Sculpting colloidal membranes through phase transformations
Shaping macroscopic 2-D thin elastic sheets through differential strains in the system is a widely studied phenomenon applicable in diverse areas such as flexible electronics, origami and tissue growth. In contrast, at the ... -
Search for Northern Hemisphere Rapidly Oscillating Ap stars
(Indian Institute of Science, 2005-04-20)Rapidly oscillating Ap (roAp) stars are cool, magnetic, chemically peculiar A-F type stars which exhibit high frequency oscillations similar to that of the famous five minute oscillations of Sun. These oscillations are ... -
Semi Conducting Metal Oxide Gas Sensors: Development And Related Instrumentation
(Indian Institute of Science, 2007-05-21)A sensor is a technological device or biological organ that detects, or senses, a signal or physical condition and chemical compounds. Technological developments in the recent decades have brought along with it several ... -
Semi-Markov Processes In Dynamic Games And Finance
(2010-07-01)Two different sets of problems are addressed in this thesis. The first one is on partially observed semi-Markov Games (POSMG) and the second one is on semi-Markov modulated financial market model. In this thesis we study ... -
Separated Local Field NMR Spectroscopy In Partially Ordered Systems - New Methodologies And Applications
(2010-09-06)Dipolar couplings are one of the major source of structural information. Due to their dependence on the distance between the nuclei and the angle of orientation of the dipolar vector with respect to the magnetic field, ... -
Shape and Load Estimation using Fiber Bragg Grating Sensors for Structural Health Monitoring of Aircraft Structures
Aerospace structures are exposed to severe loading and environmental conditions, which necessitates constant inspection and maintenance to improve safety and reliability. Currently, the aerospace industry largely depends ... -
Shape Optimization Of A Cylilndrical-Electrode Structure To Mimic The Orbitrap
(2016-11-02)The Orbitrap is a mass analyzer that employs an electrostatic field to confine ions. The mass of an ion is determined from the frequency of its axial oscillations in the Orbitrap. The Orbitrap has high resolving power and ... -
Shear Induced Transitions In Mixed Surfactant Systems And Anisotropic Colloids
(2017-06-12)This thesis deals with the non-equilibrium phenomena under shear observed mainly in bilayer forming liquid crystalline phases of mixed surfactant systems, anisotropic colloidal dispersions as well as Langmuir monolayers ... -
Shift-like Automorphisms of Ck
(2018-01-03)We use transcendental shift-like automorphisms of Ck, k > 2 to construct two examples of non-degenerate entire mappings with prescribed ranges. The first example exhibits an entire mapping of Ck, k>2 whose range avoids a ... -
Shortest Length Geodesics on Closed Hyperbolic Surfaces
(2018-01-31)Given a hyperbolic surface, the set of all closed geodesics whose length is minimal form a graph on the surface, in fact a so called fat graph, which we call the systolic graph. The central question that we study in this ... -
Simultaneous Studies Of Electrical Contact Resistance And Thermal Contact Conductance Across Metallic Contacts
(2010-12-07)Contact resistance is the most important and universal characteristic of all types of electrical and thermal contacts. Accurate measurement of contact resistance is important, because it serves as a measure for judging the ... -
Single and Multi-player Stochastic Dynamic Optimization
(2018-04-06)In this thesis we investigate single and multi-player stochastic dynamic optimization prob-lems. We consider both discrete and continuous time processes. In the multi-player setup we investigate zero-sum games with both ... -
Single Pulse Studies Of Wide Profile Drifting Pulsars - A Probe Of Pulsar Magnetospheres
(2011-02-07)The detailed nature of radio emission processes of pulsars and the exact location and distribution of the pulse emitting regions are still shrouded with mystery. Pulsars with drifting subpulses are considered as an important ... -
Slow Dynamics In Complex Fluids : Confined Polymers And Soft Colloids
(2015-08-05)The thesis describes the study of slow dynamics of confined polymers and soft colloids. We study the finite size effect on the dynamics of glassy polymers using newly developed interfacial microrheology technique. ... -
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 ... -
Small Angle Sensing/Measurement Using 'Pattern Imaging' Method - Few Investigations
(2010-07-14)The present thesis concerns with a few investigations on sensing/measurement of small angle rotation/tilt using Pattern Imaging Method. The methodology involves looking at the tailored-objects located adjacent to the ... -
Soft Matter : Routes To Rheochaos, Anomalous Diffusion And Mesh Phases
(2008-10-06)Soft condensed matter (SCM) systems are ubiquitous in nature. SCM systems contain mesoscopic structures in the size range 10 nm to 1 am that are held together by weak entropic forces. These materials are therefore easily ... -
Soft Matter Under Electric Field And Shear
(2010-06-09)‘Soft condensed matter’ is a newly-emerged sub-discipline of physics concerned with the study of systems that are mechanically soft such as colloids, emulsions, surfactants, polymers, liquid crystals, granular media and ...
