Axially Homogeneous Turbulent Convection at High Rayleigh Numbers : Scaling Laws for Flux and Spectra
(2018-05-30)Natural turbulent convection studies encompass a wide range of flows occurring in nature, for example, atmospheric and oceanic flows, con-vection in the Earth’s mantle, convection in the stars and also in many engineering ... -
Unraveling the Evolutionary Advantages of Crosstalk Between Two-Component Signalling Systems of M tuberculosis
(2018-05-29)M. tuberculosis (Mtb) senses and responds to changes in its environment primar-ily through two-component signalling systems (TCSs). Each TCS contains a trans-membrane histidine kinase (HK ) protein and a cytoplasmic response ... -
Intent- driven Correspondence and Registration of Shapes
(2018-05-29)Registration means to bring two or more shapes into a suitable relative configuration (position and orientation). In its major applications like 3D scan alignment, the aim is to coalesce data and regions originating from ... -
Estimation of Stress Concentration and Stress Intensity Factors by a Semi-Analytical Method
(2018-05-29)The presence of notches or cracks causes stresses to amplify in nearby regions. This phenomenon is studied by estimating the Stress Concentration Factor (SCF) for notches, and the Stress Intensity Factor (SIF) for cracks. ... -
Characterization of Different Slags for Bulk Geotechnical Applications
(2018-05-29)Generation of wastes in the form of liquid, solid or gas is inevitable in any industry.Industrial Solid Waste is the waste that is generated from an industrial or manufacturing process and includes the waste generated from ... -
A Study on the Effect of Inhomogeneous Phase of Shape Memory Alloy Wire
(2018-05-25)The present study in this thesis has attempted to resolve one of the key aspects of enhancing predictability of macroscopic behavior of Shape Memory Alloy (SMA) wire by considering variation of local phase inhomogeneity. ... -
Multi-scale Modelling of Lamellar Mesophases
(2018-05-25)Surfactants are amphiphilic molecules which self-assemble at the interface in oil-water-surfactant mixtures such that the hydrophobic part, called tail, stays in oil and the remaining part, called head, resides in hydrophilic ... -
Modelling How Refractoriness to Interferon Compromises Interferon-Free Treatment of Hepatitis C Virus Infection
(2018-05-25)Hepatitis C virus (HCV) infection globally affects 130-150 million people. It causes both acute and chronic infections. Due to the severe side effects and low success rates of interferon based treatments, which formed the ... -
Stochastic Models Suggest Guidelines for Protocols with Novel HIV-1 Interventions
(2018-05-25)The treatment of human immunodeficiency virus (HIV-1) infection faces the challenge of drug resistance. The high mutation rate of HIV-1 allows it to develop resistance against all available drugs. New mechanisms of ... -
Quantification of Uncertainties in Urban Precipitation Extremes
(2018-05-25)Urbanisation alters the hydrologic response of a catchment, resulting in increased runoff rates and volumes, and loss of infiltration and base flow. Quantification of uncertainties is important in hydrologic designs of ... -
Estimation of Daily Actual Evapotranspiration using Microwave and Optical Vegetation Indices for Clear and Cloudy Sky Conditions
(2018-05-25)Evapotranspiration (ET) is a significant hydrological process. It can be studied and estimated using remote sensing based methods at multiple spatial and temporal scales. Most commonly and widely used remote sensing based ... -
Development of Multipoint Haptic Device for Spatial Palpation
(2018-05-25)This thesis deals with the development of novel haptic array system that can render distributed pressure pattern. The haptic devices are force feedback interfaces, which are widely seen from consumer products to tele-surgical ... -
Mechanical and Corrosion Properties of Selective Laser Melted Alloys
(2018-05-23)Selective laser melting (SLM) of metallic powders is an additive manufacturing technique that is widely employed to produce 3D components, and is fast becoming an important method for manufacturing near-net shape and complex ... -
Studies in Water Treatment : Defluoridation using Adsorption, Denitrification using a Microbial Fuel Cell, and Contaminant Removal using Solar Distillation
(2018-05-23)This thesis includes both experimental and modelling studies on the treatment of drinking water. Three aspects were studied: (i) removal of fluoride (F– ) by adsorption, (ii) removal of fluoride and other contaminants by ... -
A Numerical Study of Changes to Flow Organization and their Prognostic Measures
(2018-05-23)Flow induced self-oscillations cause acoustic pressure oscillations of large amplitude in pipe flows. If Reynolds number is treated as a parameter, these floinduced oscillations occur only at discrete and critical values ... -
Whisker Growth from Electrodeposited Sn Coatings - Developing Materials Science and Mechanics Based Insights
(2018-05-23)Pure Sn and Sn-alloys are widely used in electrical and microelectronic devices as protective layer to prevent oxidation of Cu conductors and also as a component of Pb-free, Sn-based solders. Sn coatings, typically 0.5-10 ... -
