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 ... -
Geometric And Radiometric Estimation In A Structured-Light 3D Scanner
(2013-10-17)Measuring 3D surface geometry with precision and accuracy is an important part of many engineering and scientific tasks. 3D Scanning techniques measure surface geometry by estimating the locations of sampled surface points. ... -
Geometric and Topological Methods for Biomolecular Visualization
Biomolecules like proteins are the basic building blocks of living systems. It has been observed that the structure of a biomolecule plays an important role in defining its function. In this thesis, we describe novel ... -
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 ... -
Geometric Calibration and Shape Refinement for 3D Reconstruction
This thesis is a contribution towards the methods of 3D reconstruction in computer vision. Most of the 3D reconstruction methods are based on either the principle of triangulation or the principle of photometry. In this ... -
A Geometric Framework For Vision Modeling In Digital Human Models Using 3D Tessellated Head Scans
(2011-08-25)The present work deals with the development of a computational geometric framework for vision modeling for performing visibility and legibility analyses in Digital Human Modeling (DHM) using the field-of-view (FoV), estimated ... -
Geometric invariants for a class of submodules of analytic Hilbert modules
Let $\Omega \subseteq \mathbb C^m$ be a bounded connected open set and $\mathcal H \subseteq \mathcal O(\Omega)$ be an analytic Hilbert module, i.e., the Hilbert space $\mathcal H$ possesses a reproducing kernel $K$, the ... -
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 ... -
Geometrical and Topological Properties of CMB Polarization Fields
Cosmic Microwave Background (CMB) is a relic from the early Universe. It was generated due to the physical processes in the early Universe during an epoch known as the recombination or decoupling epoch. The CMB has highly ... -
Geometry of normed linear spaces in light of Birkhoff-James orthogonality
In this thesis, we have tried to understand the geometry of normed spaces in the light of Birkhoff-James orthogonality. Using the first two chapters to give introductory notes and to establish relevant notations and ... -
