Design, Implementation, and Analysis of a TLB-based Covert Channel on GPUs
GPUs are now commonly available in most modern computing platforms. They are increasingly being adopted in cloud platforms and data centers due to their immense computing capability. In response to this growth in usage, ... -
Development of Solution Methodologies for Multi-Product, Multi-Component, Production-Inventory Planning Problem in a Component Remanufacturing Environment considering Backorders and Quantity Discounts
Closed loop supply chain has been an area of research which has evolved over the years. This thesis aims to address a problem in this domain, specifically from the perspective of an Original Equipment Manufacturer (OEM) ... -
Photo magnetic Investigation and Magneto-structural Correlation of Switchable Molecular Magnetic Materials
Modern life without magnetic materials is almost impossible to imagine. Mobile phones, telecommunication, navigation, computer, television, credit cards, medical equipment, data storage devices, and sensors are an integral ... -
Raman Spectroscopy on Few layer graphene
Graphene is a two-dimensional allotrope of carbon exhibiting planer honeycomb lattice structure.1 A carbon atom in graphene makes three σ-bonds with the neighbouring atoms in the plane and one π-bond perpendicular to the ... -
An MLIR-Based High-Level Synthesis Compiler for Hardware Accelerator Design
The emergence of machine learning, image and audio processing on edge devices has motivated research towards power-efficient custom hardware accelerators. Though FPGAs are an ideal target for custom accelerators, the ... -
A Fundamental Investigation Of Discrete Liquid, Gas And Fines Flow In A Random Packed Bed Along With Applications
The discontinuous nature of liquid flow in a random packed bed is observed in many chemical engineering and metallurgical applications like blast furnace and heap leaching. So, to model the liquid flow in these systems, ... -
Beamforming and Target Tracking Methods for Active RF Phased Array Seekers
The end game guidance and control of an interceptor for neutralization of a hypersonic vehicle or a maneuvering aerial target is a challenging problem. This problem can be addressed in two ways: through faster autopilot ... -
Average Reward Actor-Critic with Deterministic Policy Search
The average reward criterion is relatively less studied as most existing works in the Reinforcement Learning literature consider the discounted reward criterion. There are few recent works that present on-policy average ... -
Exploring dissipation dynamics in low-dimensional superconductor
Technological advances in the past decade in fabricating two-dimensional superconducting materials with low disorder have enabled exploring many exciting phases. In recent times, two-dimensional superconductors have been ... -
Empirical Study on a Class of Problems for Omnichannel Retailing in India with Special Reference to Apparel Industry
Omnichannel retailing is an integrated experience that melds the advantages of physical stores with information-rich online shopping. To offer a seamless omnichannel shopping experience, retailers need to understand what ... -
3D-Printing of Lunar Soil Simulant by Direct-Extrusion method.
The extrusion-based additive manufacturing (EAM) technique is recently being widely employed for the 3D printing of complex-shaped components made of ceramic powder (containing irregular-shaped particles) when it is cast ... -
Self-Assembled Coordination Architectures for Fluorescence Modulation, Photocatalysis, and Light Harvesting
Self-assembly and noncovalent interactions play a pivotal role in the design of complex, and intricate functional structures. Among several design approaches, metal-ligand coordinationdriven self-assembly has emerged as ... -
Constrained Stochastic Differential Equations on Smooth Manifolds.
Dynamical systems with uncertain fluctuations are usually modelled using Stochastic Differential Equations (SDEs). Due to operation and performance related conditions, these equations may also need to satisfy the constraint ... -
Activity induced phase separation and the emergence of liquid crystal phases in chiral and achiral systems, and development of an efficient method to compute the entropy of various liquid crystal phases
The phase behaviour of shape-anisotropic particles is an emerging field of research that gives rise to various liquid crystal phases. In this thesis, we explore various equilibrium and non-equilibrium properties of ... -
Deciphering the role of host protein HuR in RNA virus life cycle and pathogenesis: Hepatitis C Virus and SARS-CoV-2 as exemplars.
Viruses pose a major threat to human health and the ongoing SARS-CoV-2 pandemic proves as the best evidence for that. Historically, RNA viruses have a major potential to cause such pandemics. They utilise RNA binding ... -
Studies on Δ40p53 mediated regulation of specific coding and non-coding RNAs: Consequences on cellular processes
p53 is a crucial transcriptional regulator which influences almost every possible pathway that impinges on the life of a cell. As expected of such an instrumental protein, the molecular network of p53 is as diverse as it ... -
Silk-based Biomaterials for Wound Care and Tissue Regeneration
For most individuals, wound healing is a highly organized, straightforward process. However, there are instances where external intervention becomes necessary to support the body’s innate healing mechanism. In this thesis, ... -
Optoelectronic and Magnetic Properties of 2D Layered Organic-Inorganic Hybrids and Selected Transition Metal Oxides
