Multiband Modelling and Radio Observations of Gamma Ray Burst Afterglows
The widely popular and successful standard fireball model for Gamma Ray Burst (GRB) afterglows is based on ultra-relativistic external shocks sweeping up matter around the explosion site to accelerate electrons up to GOV ... -
Multicarrier Effects In High Pulsed Magnetic Field Transport And Optical Properties Of Mercury Cadmium Telluride
(2011-01-17)This thesis on multicarrier effects in the magnetotransport and optical properties of Mercury Cadmium Telluride (MCT or HgCdTe) covers mainly: design, construction and calibration of a 12T 4K and 19T 77K pulsed high magnetic ... -
Multidimensional Multicolor Image Reconstruction Techniques for Fluorescence Microscopy
(2018-06-26)Fluorescence microscopy is an indispensable tool in the areas of cell biology, histology and material science as it enables non-invasive observation of specimen in their natural environment. The main advantage of fluorescence ... -
Multiphase gas in the baryon cycle: from jellyfish galaxies to turbulent galactic outflows
The formation and evolution of galaxies are shaped not only by gravity but also by the complex behaviour of gas—the dominant baryonic component within and around galaxies. This gas spans a wide range of temperatures, ... -
The multiphase interstellar medium: A study of various physical and kinematical properties
Interstellar medium (ISM) is the relatively empty space in between the stars. It has different phases, like, neutral, molecular, and ionized. Neutral interstellar medium, which is pervaded all over the galaxy, is sometimes ... -
Multiple Stable States and Abrupt Transitions in Spatial Ecosystems
Ecosystems can exhibit multiple stable states at similar external conditions. Such systems shift from one stable state to another abruptly and discontinuously, when they cross certain threshold parameters. Some examples ... -
Multiscale Modeling of Molecular Sieve Membranes
Gases permeating through nanopores experience selective adsorption with sub-diffusive dynamics. In this work we investigate how the physicochemical properties of nanoporous membranes influence adsorption dynamics of gases, ... -
A Multiscale Modeling Study of Iron Homeostasis in Mycrobacterium Tuberculosis
(2018-05-10)Mycobacterium tuberculosis (M.tb), the causative agent of tuberculosis (TB), has remained the largest killer among infectious diseases for over a century. The increasing emergence of drug resistant varieties such as the ... -
Multiscale Simulation of Nucleic Acid Nanostructures
Nucleic acids, namely DNA and RNA, are arguably the most studied biological molecules. Utilizing the key properties of nucleic acids, such as their persistence lengths and Watson-Crick base-pairing complementarity, ... -
Multiscaling in three-dimensional fluid turbulence
Fluid turbulence remains one of the most fascinating unsolved problems in Physics. Different aspects of it have attracted physicists and fluid dynamicists for decades. This thesis studies multiscaling of velocity structure ... -
Nanocrystalline Titania Based Dye Sensitized Solar Cells - Effect Of Electrodes And Electrolyte On The Performance
(2015-07-22)Dye-sensitized solar cells (DSC) have attracted considerable scientific and industrial interest during the past decade as an economically feasible alternative to conventional photovoltaic devices. DSCs have the potential ... -
Nanodevices of Graphene, Carbon Nanotubes and Flow Behaviour of Graphene Oxide Gel
(2018-05-09)In the last three decades carbon nanomaterials such as fullerenes, carbon nanotubes and graphene have attracted significant attention from the scientific community due to their unique electronic, optical, thermal, mechanical ... -
Nanoscale spatial and temporal response of lipid membranes interacting with biomolecules and nanoparticles
The cell membrane is the first point of interaction whenever any external biomolecule or nanoparticle encounters a cell. Thus the nature of interactions between the cell membrane and various proteins, nanoparticles, and ... -
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 ... -
Near Optimal Non-malleable Codes and Leakage Resilient Secret Sharing Schemes
A well-studied class of attacks on cryptosystems called "side-channel attacks", stems from the additional access that an adversary can get due to the susceptibility of the hardware on which the cryptosystem (e.g., digital ... -
Nega-base computer arithemetic-theory and applications
This dissertation presents a detailed study of negative base number representation—the theory as well as the development of suitable algorithms for building the arithmetic unit of a digital computer. The idea of negative ... -
Neuronal Correlations And Real-Time Implementation Of Spatio-Temporal Patterns Of Cultured Hippocampal Neural Networks in vitro
(2011-01-19)The study of cultured neuronal networks has opened up avenues for understanding the ion channels, receptor molecules, and synaptic plasticity that may form the basis of learning and memory. The hippocampal neurons prepared ... -
