Preparation and Optical Properties of Hybrid Assemblies of Metallic Gold Nanoparticles and Semi-Conducting CdSe Quantum Dots
(2018-04-16)This thesis summarizes the methods of preparation and optical properties of hybrid assemblies of Au NPs and cadmium selenide (CdSe) QDs. First chap-ter deals with the literature survey and theoretical aspects of plasmonics ... -
Pulsed Laser Ablated Dilute Magnetic Semiconductors and Metalic Spin Valves
(2018-04-02)Spintronics (spin based electronics) is a relatively new topic of research which is important both from the fundamental and technological point of view. In conventional electronics charge of the electron is manipulated and ... -
Randall-Sundrum Model as a Theory of Flavour
(2018-04-11)The discovery of the Higgs boson by the LHC provided the last piece of the puzzle neces- sary for the Standard Model (SM) to be a successful theory of electroweak scale physics. However there exist various phenomenological ... -
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 ... -
Spatial Filtering Techniques for Large Penetration Depth and Volume Imaging in Fluorescence Microscopy
(2018-04-06)In the past two decades, Fluorescence microscopy has imparted tremendous impact in Biology and Imaging. Several super-resolution Fluorescence imaging techniques (e.g. PALM, STED, STORM, 4Pi and structured illumination) ... -
Spiral-Wave Dynamics in Ionically Realistic Mathematical Models for Human Ventricular Tissue
(2018-04-18)There is a growing consensus that life-threatening cardiac arrhythmias like ven- tricular tachycardia (VT) or ventricular fibrillation (VF) arise because of the formation of spiral waves of electrical activation in cardiac ... -
Stochastic Dynamical Systems : New Schemes for Corrections of Linearization Errors and Dynamic Systems Identification
(2018-03-23)This thesis essentially deals with the development and numerical explorations of a few improved Monte Carlo filters for nonlinear dynamical systems with a view to estimating the associated states and parameters (i.e. the ... -
