Alluaudite Class of High-Voltage Cathodes for Sodium-Ion Battery Applications: A Synthesis, Structure, Property Correlation Study
The work presented in this thesis demonstrates alluaudites as a niche class of compounds forming the rich treasure house of sodium insertion hosts. The potential of this open frame-worked alluaudites is immense and ... -
Applications of Holography
This thesis consists of four parts. In the first part of the thesis, we investigate the phase structure of Einstein-Maxwell-Scalar system with a negative cosmological constant. For the conformally coupled scalar, an ... -
Internal resonances and nonlinearities in atomically thin resonators
The advent of carbon nanotubes (CNTs) and atomically thin membranes such as Graphene and layered transition metal chalcogenides (TMDs) have spurred research in the area of Nanoelectromechanical Systems (NEMS) due to their ... -
Bayesian Techniques for Joint Sparse Signal Recovery: Theory and Algorithms
This thesis contributes new theoretical results, solution concepts, and algorithms concerning the Bayesian recovery of multiple joint sparse vectors from noisy and underdetermined linear measurements. The thesis is written ... -
A Novel Algorithm-Architecture Co-Designed System for Dynamic Execution-Driven Pre-Silicon Verification
In EDA industry, design-under-test (DUT) is a pre-silicon digital design which is still undergoing testing phase. We perform functional-verification of a DUT to verify whether the DUT conforms to the specifications. Functional ... -
Role of conserved features of initiator tRNA and ribosome heterogeneity in translation initiation in Escherichia coli
Translation is one of the fundamental and core cellular processes catalysed by a ribonucleoprotein complex called ribosome. The process involves four major steps: initiation, elongation, termination and recycling. Initiation ... -
Propulsive Performance of Pitching Foils Investigated with Viscous Vortex Particle Method
Unsteady flapping foil based thrusters have emerged as ideal candidates for enabling propulsion in bioinspired and bio-mimetic devices such as autonomous underwater vehicles. To a large extent, this emergence has been ... -
Role of TCP transcription factors in seedling development, leaf morphogenesis and senescence in Arabidopsis thaliana
The TCP gene family encodes non-canonical bHLH transcription factors that act as key regulatory molecules in diverse developmental processes in plants including organ morphogenesis, plant architecture, leaf maturation, and ... -
Characterization of a large scale hypersonic shock tunnel and investigation of the effect of roughness on a large cone boundary layer flow
High speed flight is ridden with engineering challenges, some of which have been studied for decades with only minor improvements. Boundary layer transition to turbulence in highMach number flow is one such topic, which, ... -
Design and Synthesis of Cyclic Diselenides and Selenenyl Sulfides for Biomimetic Applications
Hydrogen peroxide (H2O2) plays important roles in cell signaling and redox reactions. However, elevated levels of H2O2 and organic peroxides induce oxidative stress, resulting in damage to biomolecules such as DNA, ... -
Experimental Investigations Into Fracture and Fatigue Behavior Of Plain and Reinforced Concrete Beams Using Acoustic Emission Technique
Concrete is the most widely used material in the world for construction of infrastructures and there are quite a few gaps in understanding its behaviour under different loads. Fracture in concrete occurs at pre-existing ... -
Phononic bandgap engineering in cellular periodic structures and mechanical metamaterials
A methodology has been developed for the computation of phononic band structure of cellular periodic structures, structures with spatially repetitive patterns, using Frequency domain Spectral Finite Element Method along ... -
Genetics of Glioblastoma: Insights into Biology and Therapy Resistance
The central nervous system contains the neural stem cells which differentiate and give rise to the neurons as well as the glial cells which are non-neuronal in nature and provide support and protection to neurons. Unlike ... -
Near Optimal Non-malleable Codes and Leakage Resilient Secret Sharing Schemes
A well-studied class of attacks on cryptosystems called "side-channel attacks", stems from the additional access that an adversary can get due to the susceptibility of the hardware on which the cryptosystem (e.g., digital ... -
High-Resolution Charge Density Studies on Electronic Nature of Weak Interactions and Correlation of Molecular Conformation with Packing in Solid State
The thesis entitled “High-Resolution Charge Density Studies on Electronic Nature of Weak Interactions and Correlation of Molecular Conformation with Packing in Solid State” consist of five chapters. Chapter 1 is a brief ... -
Price of Privacy of Smart Meter Data
Smart meter data can be used by the utility for billing the consumers timely along with power theft detection, demand side management, distribution network planning, consumer segmentation, load forecasting, fault detection, ... -
Protein Folding, Function and Aggregation Role of Co-solvents and Topological Frustration
Proteins are biological macromolecules formed by sequentially joining natural amino acids through peptide bonds. The sequence of amino acids in a protein chain determines its three dimensional structure under physiological ... -
Disruptive Approaches to Address Performance & Reliability Challenges in 2-Dimentional (2D) Material Based Transistors & Memories
In 2020, Apple introduced its most advanced laptop that has the A14 Bionic processor. The very first processor, Intel’s 4004, was launched in 1971 and had a transistor (the basic building block of a processor) density of ... -
The Effect of Gamma Radiation on Protein Structure and Dynamics
Gamma radiation being the most energetic form of electromagnetic radiation has applications in number of different fields such as in medicine for treating cancer, food sterilization and in astronomy for studying phenomenon ... -
Effects of Steroid Hormones on Insulin Sensitivity and Lipogenesis: An Insight into the Involvement of the Wnt Signaling Pathway
The shift in maternal energy metabolism characteristic of pregnancy is thought to be driven by various hormonal changes, especially of ovarian and placental steroids. In this context, the effect of estradiol (E2), progesterone ...
