Development of a Flexible Actuator and Motion Planning for Endoscopic Robots
Endoscopy is a procedure by which a long flexible device called the `endoscope' is inserted into a patient's gastro-intestinal(GI) tract primarily for diagnosis. An endoscope is typically equipped with a camera, ... -
Structure property correlation studies on Ca-modified Ba(Ti, Zr/Sn)O3 piezoceramics
In this thesis we have investigated the structure, property correlation of the lead-free piezoelectric ceramic of (Ba,Ca) (Ti,Zr/Sn)O3 system. A self-consistent set of experimental techniques such as X-ray powder diffraction, ... -
Subsurface Profiling of Shallow Bedrock Sites by Integrated Approach and Site-specific 2d Site Response Analysis
Estimation of reliable site effects and amplifications are important for seismic design. There are several 1D and 2D large scale site response analyses were reported in the literature and very limited shallow bedrock small ... -
Biodiesel from Estuarine Microalgae - Diatoms
Rapidly depleting fossil fuel reserves with the burgeoning demand, associated escalating GHG footprint, and changes in the climate necessitated the exploration of alternate sustainable energy resources that are renewable, ... -
A Unified Framework For Micromechanical Damage Modeling In Laminated Polymer Matrix Composites
A unified numerical framework for progressive damage analysis in polymer matrix composite (PMC) laminates has been developed by explicitly accounting for damage progression at the micro-level. A three-dimensional repeating ... -
Structural Reliability Estimation Using Markov Chain Splitting and Girsanov’s Transformation Based Methods
The work reported in this thesis is in the area of Monte Carlo simulation based methods for structural reliability estimation with special focus on strategies to reduce sampling variance of the estimator for the probability ... -
Molecular Dynamics simulations reveal the role of membrane cholesterol in the pore forming pathway of Cytolysin A
We investigate the interactions of pore-forming toxins (PFTs) with cholesterol-rich membranes through atomistic molecular dynamics simulations. The PFT of interest is Cytolysin A (ClyA or HlyE). Cytolysin A (ClyA), an ... -
A Generalised Modelling of Piezoelectric Composite Shells and Plates using Variational Asymptotic Method
In several fields of engineering, researchers are actively pursuing the possibility to use smart materials such as piezoelectric composites in order to make the structure smart. Piezoelectric materials have the capability ... -
Strain Hardening in Extruded Pure Magnesium
There has been a surge in interest in wrought magnesium alloys for structural applications in automotive industry. However, the application of wrought alloys is limited by its poor plasticity, due to its inherent strong ... -
Spherical Indentation Response of Bulk and Thin Film Shape Memory Alloys
Shape memory alloys (SMAs) have the ability to recover large strains upon undergoing a thermomechanical cycle. In addition to being used as structural elements, they can be patterned as thin films which can be employed in ... -
Biofilm Reactors for Greywater Treatment
Greywater (GW) is the fraction of wastewater discharged in houses that has not been contaminated with faeces. The average volumes of greywater generated in the households of Bengaluru varies between 40-70 litres/cap/day ... -
An advection velocity correction scheme for interface tracking using the level-set method
An advection velocity correction (AVC) scheme for interface tracking using the level-set method is presented in this thesis. The key idea is to apply a correction to the interface advection velocity at points adjacent ... -
Preliminary Investigation into the Cold Plasma Powered Water Gas Shift Reaction – Experiments And Analysis
Water gas shift reaction (CO + H2O ↔ H2 + CO2) is a CO oxidation reaction in the presence of steam resulting in the formation of H2 and CO2. Traditionally, water gas shift (WGS) reaction is achieved using multiple catalytic ... -
Structure-Property Correlation in Binary Immiscible Polymer Blends Compatibilized by Mutually Miscible Homopolymer and Carbonaceous Nanoparticles
The thesis systematically studies the various morphology, mechanical properties, crystallization kinetics and compatibilization effects of homopolymers, carbonaceous nanoparticles such as multiwall carbon nanotubes (MWNTs), ... -
Effect of processing on texture and microstructure in Aluminium-Lithium alloys and its consequences on mechanical properties
Lightweight Aluminium -Lithium based alloys have high potential for use in aerospace structural components. However, large anisotropy in mechanical properties restricts the use of these alloys. The alloy AA2195 (Al-Li-Cu-Mg-Ag-Zr) ... -
Influence of Western Ghats Orography on Temporal and Spatial Distribution of Rainfall over South Asia
The Western Ghats (WG) orography that runs along the western coast of peninsular India, is a long and narrow mountain chain with an average height of about 1200 meters. The orientation of this orography is approximately ... -
Characterization of Corneal Lens of Drosophila melanogaster and its Genetic Mutants using Atomic Force Microscope and Scanning Electron Microscope
Drosophila melanogaster (the fruit fly) is a widely used model organism for the study of human disease condition and genetic pathways due to the high degree of gene conservation between fly and human. The compound eyes of ... -
Development of wrought Mg-Li based alloys with improved strength and ductility
A comprehensive investigation has been undertaken to develop cold rolled Mg-Li based alloys with tensile properties superior to the existing commercial or experimental Mg-Li based alloys. In this endeavor, melting and ...
