Analysis of Fracture Processes in Steel Fibre Reinforced Cementitious Composites using Acoustic Emission Testing
Plain concrete has low tensile strength. Steel fibre reinforced concrete (SFRC) is an alternative to plain concrete. One of the major reasons of using the SFRC is due to its high tensile strength. The fracture process ... -
Electronic structure of two-dimensional materials: Effect of point defects and moiré patterns
In the last two decades, research on two-dimensional (2D) materials has gained momentum due to their capability to host a wide range of novel phases of matter. These materials have also found applications in electronic, ... -
Modeling and verification of database-accessing applications
Databases are central to the functioning of most IT-enabled processes and services. In many domains, databases are accessed and updated via applications written in general-purpose lan- guages, as such applications need ... -
Fundamental aspects of the interface engineering in the heavy metal/ferromagnet-based perpendicularly magnetized systems
The ferromagnetic (FM) material finds its applications due to the property of spontaneous magnetization. An FM object can hold its state of magnetization unless any external stimuli change it. The easy manipulation of its ... -
Analysis and Methods for Knowledge Graph Embeddings
Knowledge Graphs (KGs) are multi-relational graphs where nodes represent entities, and typed edges represent relationships among entities. These graphs store real-world facts such as (Lionel Messi, plays-for-team, Barcelona) ... -
Study of Metal and Oxide based Synaptic Transistors by Ionic liquid Gating for Neuromorphic Computing
Neuromorphic Computing (NC), which emulates neural activities of the human brain, is considered for low-power implementation of artificial intelligence. Towards realizing NC, fabrication, and investigations of synaptic ... -
Microscopic Investigations of Dynamics of Linear Diatomics and Ions in Water and Aqueous Binary Mixtures
This thesis explores the structural and dynamical aspects of small, charged and neutral, solute molecules in both pure water and in aqueous binary mixtures, with emphasis on water-ethanol binary mixture. We employ both ... -
Integrative modeling of NS3 helicase function with molecular kinetics, molecular simulations and machine learning
The viral NS3 helicase is a crucial enzyme involved in the RNA replication of positive strand ssRNA viruses of the Flaviviridae family. The NS3 is an active motor that binds RNA and couples ATP hydrolysis to the mechanical ... -
Techniques for estimating the direction of pointing gestures using depth images in the presence of orientation and distance variations from the depth sensor
A significant part of our daily life is spent interacting with various computing devices, mobile phones, etc. Soon, robots and drones may become common in daily life, as might be virtual reality based interfaces. Currently, ... -
Dynamics and Rheology of Non-colloidal Suspensions: Active and Soft Deformable Particles
Classical works on the suspensions of rigid spherical and ellipsoidal particles have been carried out by Einstein and Jeffery. However, in nature and industry, we come across materials that are either deformable or active. ... -
Quantum walks and spatial search on regular graph
Random walks and algorithms based upon them are used widely to explore large state spaces that arise while studying physical systems. In this thesis, we will discuss some quantum generalizations of such algorithms and study ... -
N-Heterocyclic Carbene (NHC)-Catalyzed Stereoselective Synthesis of Six-Membered Heterocycles and Carbocycles
N-Heterocyclic carbene (NHC) based catalysis is employed for the generation of α,β-unsaturated acylazoliums followed by their interception with various nucleophiles, the formal [3+3] annulation reactions for the construction ... -
Vapor Mediated Interaction in Droplets
Controlling internal flow in evaporating sessile droplets is desirable across applications ranging from lab-on-chip medical diagnostics, DNA profiling to surface patterning. Diffusion-limited evaporation in droplets exhibits ... -
Designed Synthesis and Electron Microscopy Investigation of Layered Materials Hybrids for Targeted Applications
Post-discovery and advancement in graphene, the field of layered materials, have gained enormous research interest. These materials have unique and diverse range of properties. Layered materials further provide an opportunity ... -
Analytical Applications of Bile Acid-derived Soft Materials
Supramolecular gels are soft materials with solid-like properties such as supporting weight and retaining shape; and some liquid-like features which make them injectable, printable, etc. On the other hand, lanthanide-based ... -
Correlation, superconductivity, and topology in twisted and untwisted layered systems
This thesis is an effort to understand some of the interesting features induced by strong correlation - superconductivity, topology, non-Fermi liquid (NFL) in two dimensional (2D) layered materials. 2D layered materials ... -
Analysis of Transcritical CO2 and CO2+ Propane Mixtures for Tropical Cooling Applications
The increasing global average ambient temperatures coupled with stringent environmental regulations has turned the focus on natural working fluids such as Carbon dioxide (CO2), and hydrocarbons for use in the refrigeration ... -
HIV-1 and SARS-CoV-2 immunogen design
Human Immunodeficiency Virus (HIV-1) is the aetiologic agent of AIDS. Presently there are ~38 million HIV-1 infected individuals worldwide and ~1 million deaths in 2019. Since its discovery, the quest for vaccine candidate ... -
High Performance GPU Tensor Core Code Generation for Matmul using MLIR
State of the art in high-performance deep learning is primarily driven by highly tuned libraries. These libraries are often hand-optimized and tuned by expert programmers using low-level abstractions with significant effort. ... -
