An Empirical Study of Transformative Learning Resulting Due to Profession Change
A career choice may emerge or be adopted due to personal interest or to balance a range of factors like familial influences, educational qualifications and economic considerations. Once a choice has been made, some follow ... -
Support Recovery from Linear Measurements: Tradeoffs in the Measurement-Constrained Regime
In this thesis, we study problems under the theme of discovering joint sparsity structure in a set of high-dimensional data samples from linear measurements. Our primary focus is on the regime where the number of samples ... -
Estimation of Glacier Mass Balance at Basin Scale in the Himalaya for Recent Decades and Future
The Himalayan glaciers are a major source of perennial river systems which support the livelihood of millions of people in south Asia. Therefore, it is important to understand changes in water resources due to changes in ... -
Fabrication and Characterization of Nanostructured Antibacterial Surfaces
Bacterial antibiotic resistance is becoming wide spread due to the excessive and unregulated use of antibiotics in healthcare and agriculture. At the same time the development of new antibiotics has become slow. Adding ... -
Role of gamma oscillations in processing of natural stimuli
Gamma oscillations (~30-80 Hz) are a prominent signature of electrophysiological signals recorded from the brain with proposed roles in various cognitive functions such as attention and visual perception. Although gamma ... -
Zeolitic Imidazolate Framework (ZIF-8) Supported Nanoparticles: Synthesis and Applications
Nanoparticles have gained great interest in various fundamental and applied areas of science and technology due to their tunable size dependent properties which is not achievable by their bulk counterparts. Nanoparticles ... -
Influence of Surface Topography and Roughness on Lubrication, Friction and Scuffing in High Hardness Steels
In tribology engineering, friction control is a significant challenge. The interacting surfaces of mechanical components are typically designed for best efficiency during tribological operations and are primarily achieved ... -
Understanding the dynamics and evolution of cratons
The earth is the only rocky planet in the solar system that exhibits plate tectonics. One of the basic tenets of plate-tectonics is that it recycles the lithosphere within a few hundred million years. No oceanic lithosphere, ... -
Mechanistic insights into the effects and applications of shockwaves in prokaryotic and eukaryotic organisms
Shock waves are non-linear waves propagating at speeds greater than the speed of sound, with a unique characteristic of instantaneously increasing the pressure, temperature and density of the medium through which they ... -
Studies on Fracture in Ductile Bulk Metallic Glasses
Bulk metallic glasses (BMGs) possess very attractive mechanical properties like high yield strength (~ 2 GPa), high elastic strain limit (2 %), and good corrosion resistance. BMGs display fracture toughness values (in mode ... -
Problems on bend-number, circular separation dimension and maximum edge 2-colouring
Representation of graphs as the intersection graphs of geometric objects has a long history. The objective is to a nd a collection of \simple" sets S such that a given graph G is its intersection graph. We are interested ... -
Engineering 3D Organotypic Models for the Study of Breast Cancer Metastasis
Breast cancer is the most common form of cancer among women the world over. Metastasis, or, the spreading of the primary tumor to other vital organs, is the major cause of mortality in breast cancer. Metastasis is a ... -
Development of noble metal catalysts and detailed kinetic models for CO oxidation and water gas shift reactions
Noble metal (Pt, Pd, Rh) based catalysts have been highly effective for CO abatement applications such as CO oxidation and the water gas shift reaction (WGS). In the venture for development of novel catalysts, noble metal ... -
New Mechanical Methods to Join Sheets in Lap and Butt Configuration and Analytical Model to Predict and Improve Clinching Joint Strength
Mechanical joining of sheets has many advantages over other joining methods in terms of wide variety combination of similar, dissimilar and non-metallic material sheet joining. In conventional SPR joining, the rivet and ... -
Conservation and divergence of the nucleotide excision repair pathway: Comparison of UvrB and UvrC proteins from Mycobacterium tuberculosis and Escherichia coli reveal significant differences in their functional properties
This thesis is presented in three chapters divided by topics. Chapter I will begin with an overview of literature regarding different types of DNA damage, DNA repair pathways in bacteria, properties of E. coli UvrABC ... -
On the Geometry and Operator Theory of the Bidisc and the Symmetrized Bidisc
This work is concerned with the geometric and operator theoretic aspects of the bidisc and the symmetrized bidisc. First we have focused on the geometry of these two do- mains. The symmetrized bidisc, a non-homogeneous ... -
Multiplexing Nanoplasmonic Sensors
Complex biological samples such as serum contain thousands of proteins and other molecules spanning up to 13 orders of magnitude in concentration. Present measurement techniques such as protein microarrays and quantum dot ... -
On the electrical transport of weak topological insulators and Weyl semimetals
Topological insulators have garnered enormous amount of attention owing to their unique topological properties. The surface states protected by the topology of the system hold limitless potentials including topological ... -
Development and Characterization of a potent Tumor Necrosis Factor-alpha blocking agent
Tumor necrosis factor-α (TNFα), one of the major pro-inflammatory cytokines, plays a pivotal role in an effective inflammation process and immune response. TNFα interacts with two different receptors, TNFR1 and TNFR2, which ... -
Novel Deep Learning Methods for Improving Low-Dose Computed Tomography Perfusion Imaging of Brain
