A Geochemical and Sr, Ca, Mg, Li isotopic study of the Godavari River draining the Deccan basalts
Chemical weathering of continental silicate rocks releases cations and anions which are eventually precipitated as carbonates on the ocean floor. This entire process transfers carbon from the atmosphere to the oceans leading ... -
A geochemical, Nd-Sr, and stable Ca isotopic study of siliciclastic and chemical sedimentary rocks, volcanic tuffs, and authigenic glauconites from Proterozoic sedimentary basins of India
The Archean-Proterozoic transition is marked by globally synchronous changes in tectonothermal and climatic patterns along with development of widespread epicontinental seas, with extensive shelf-sedimentation. The Indian ... -
Geoelectrical Characterization for Relating Electrical Resistivity and Geotechnical Properties of Soils
This thesis proposes electrical resistivity measurement as a potential method to characterize different types of geomaterials under different environmental conditions. Electrical resistivity method is a promising non-destructive ... -
Geometric And Material Stability Criteria For Material Models In Hyperelasticity
(2013-07-17)In the literature, there are various material models proposed so as to model the constitutive behavior of hyperelastic materials for example, St. Venant-Kirchho_ model, Mooney-Rivlin model etc. The stability of such material ... -
A Geometric Approach for Discrete and Statistical Reach Analysis for a DHM with Mutable Supports
(2017-12-05)Conventional ergonomics analysis involves building physical mockups and conducting simulated operations, such that the constraints experienced by the human subjects can be directly observed. The limitations of this approach ... -
A Geometric Framework For Vision Modeling In Digital Human Models Using 3D Tessellated Head Scans

Geometric Reasoning with Mesh-based Shape Representation in Product Development
(2017-10-09)Triangle meshes have become an increasingly popular shape representation. Given the ease of standardization it allows and the proliferation of devices (scanners, range images ) that capture and output shape information as ... -
Geotechnical Behaviour Of Soil Containing Mixed Layered Illite-Smectite Contaminated With Caustic Alkali
(2008-01-29)The aim of the thesis has been to evaluate and understand the effect of caustic alkali solution of varying composition on the behaviour of expansive soil containing mixed layered minerals. Mixed layered minerals are formed ... -
Geotechnical Site Characterization And Liquefaction Evaluation Using Intelligent Models
(2009-12-09)Site characterization is an important task in Geotechnical Engineering. In situ tests based on standard penetration test (SPT), cone penetration test (CPT) and shear wave velocity survey are popular among geotechnical ... -
A Ghost Fluid Method for Modelling Liquid Jet Atomization
(2018-05-21)Liquid jet atomisation has a wide variety of application in areas such as injectors in automobile and launch vehicle combustors, spray painting, ink jet printing etc. Understanding physical mechanisms involved in the primary ... -
Global and combined global-local response sensitivity analyses of uncertain structures based on model distance measures
The work reported in this thesis is in the area of global response sensitivity analysis (GRSA) of engineering systems in which the uncertainties associated with external actions and/or system parameters need to be explicitly ... -
Global response sensitivity and reliability analyses of structural dynamical systems with parameter and excitation uncertainties
This thesis develops computational methods for global response sensitivity analysis (GRSA) and time-variant reliability analysis in structural dynamical systems with parameter and excitation uncertainties. The primary ... -
Global Retrieval of Aerosol Absorption Using Multi-Satellite Retrieval: Algorithm Development And Performance Evaluation
Aerosol absorption, quantified by single scattering albedo (SSA), is an important parameter for assessing the climatic impact of aerosols. While there are several satellites providing aerosol optical depth (AOD), the ... -
Glowworm Swarm Optimization : A Multimodal Function Optimization Paradigm With Applications To Multiple Signal Source Localization Tasks
(2009-05-05)Multimodal function optimization generally focuses on algorithms to find either a local optimum or the global optimum while avoiding local optima. However, there is another class of optimization problems which have the ... -
