On the analysis of axially loaded Euler-Bernoulli beam using Galerkin, Fourier transform, and Lie symmetry approach
The beam with axial load is one of the fundamental models in the field of physics and engineering. The applications of this model span from a guitar string to the rotating blade of a helicopter. It has an important role ... -
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 ... -
Cobalt-nhc Complexes and Diazabutadienes in Activation of Mono/Diboron Compounds and Their Application in C-b Coupling Reactions
Boronic acid(esters) have been well recognized as an indispensable coupling partner in the Suzuki-Miyaura cross coupling reactions producing a vast spectrum of molecules, applicable in the diverse field ranging from medicinal ... -
Manipulation of Spin Dynamics and Multifaceted Applications of NMR Spectroscopy to Small Molecules
The investigations have been carried out in the thesis entitled as “Manipulation of Spin Dynamics and Multifaceted Applications of NMR Spectroscopy to Small Molecules” to address the challenging problems encountered in ... -
Understanding the origins and diversification of Indian blindsnakes
Much of systematics done in the past was based on morphological data. One of the drawbacks of using morphological data is that in groups with conserved morphology, the diversity is often underestimated and relationships ... -
Study of Optoelectronic Properties of Quantum Emitter Assemblies Coupled to Graphene, Photonic and Plasmonic Materials
Nano-photonics deals with different ways to control light-matter interactions beyond the diffraction limit. In contrast to optics, which is the concept of light rays, including absorption, transmission, and reflection, ... -
Aspects of conformal field theories at finite temperature
In this thesis we have studied broadly two aspects of thermal field theory. We began by examining how the macroscopic system (described by relativistic hydrodynamics) behalves in presence of microscopic anomalies. We ... -
Development of a coarsening resistant microstructure in precipitation strengthened aluminium alloys with Zr, Ta and Hf
The work herein aims at developing precipitation-strengthened aluminium-copper (Al-Cu) alloys that can meet the current challenges of the aeronautical and automobile sectors to increase the fuel efficiency where operating ... -
Insights into signalling and crosstalk in two-component signalling systems of Mycobacterium tuberculosis
Tuberculosis (TB), caused by the pathogen Mycobacterium tuberculosis (Mtb), has very recently reclaimed the position of the leading cause of deaths in humans from a single infection agent. This suggests a dire need to ... -
Uncovering of a novel non-taxane anticancer secondary metabolite from Taxol-producing endophytic fungus: Optimization of culture parameters and whole-genome sequence analysis for improved taxane production biosynthesis.
Cancer-related mortalities and morbidities have proven to be a great health burden for human society with immense economic implications. With uncontrolled proliferation of cells as the fundamental principle underlying its ... -
Solving Inverse Problems Using a Deep Generative Prior
In an inverse problem, the objective is to recover a signal from its measurements, given the knowledge of the measurement operator. In this thesis, we address the problems of compressive sensing (CS) and compressive phase ... -
Determining Functional Parameters of Hybrid Catalysts for Sustainable Energy Storage and Conversion Applications
Generating global-scale sustainable energy systems and preserving our environment for the future at the same time are the biggest challenges. Therefore, the search for diverse energy sources which will reduce our dependency ... -
FLIPP-NAAT: A paper-based LAMP assay for point-of-care TB detection
Molecular diagnostic techniques like polymerase chain reaction (PCR) revolutionized the world of healthcare. Instead of waiting for infectious agents to physically grow as in conventional culture-based tests, genetic ... -
A Novel Neural Network Architecture for Sentiment-oriented Aspect-Opinion Pair Extraction
Over the years, fine-grained opinion mining in online reviews has received great attention from the NLP research community. It involves different tasks such as Aspect Term Extraction (ATE), Opinion Term Extraction (OTE), ... -
Effect of Single Residue Change on Conformational Dynamics of Proteins and Their Function: A Molecular Dynamics Study
Proteins undergo conformational transitions and exhibit specific motion while performing their function. A single residue change (addition, deletion, or substitution) can sometimes influence the protein dynamics and disrupt ... -
Addressing Energy and Performance Related Challenges in Networked Embedded Systems
Networked Embedded Systems comprise of spatially and functionally distributed nodes that are interconnected with one another and with the environment to achieve certain goals. The nodes are connected to one another through ... -
Structural connectivity correlates of human cognition explored with diffusion MRI and tractography
Intact structural connectivity among brain regions is critical to cognition. Structural connectivity forms the substratum for information flow between brain regions, and its plasticity is a hallmark of learning in the ... -
Construction of C-C bonds by C-H Activation: Rh(III)-Catalyzed reactions of Arenes and Heteroarenes with Maleimides and Allylic Alcohols
The thesis presents a few Rh-catalyzed C-H activations for the construction of C-C bonds. The difficulty of substitution or the arylation at the maleimide's double bond under C-H activation conditions prompted a detailed ... -
Cholinergic-receptor-independent modulation of intrinsic properties of subicular neurons through inhibition of hyperpolarization-activated cyclic nucleotide-gated channels
Acetylcholine release is vital in tuning the hippocampal theta oscillations. Subiculum, the output region of the hippocampus endowed with different neuronal subtypes, also generates theta oscillations during arousal and ... -
Liquefaction Resistance and Cyclic Response of Air - Injected Desaturated Clean Sandy Soil: Experimental and Numerical Investigations
Liquefaction has been one of the major concerns in the field of geotechnical earthquake engineering. Various mitigation techniques such as vibroflotation, deep dynamic compaction, explosive compaction, grouting, deep soil ...
