Design and Development of Fiber Bragg Grating Sensor Devices for Aerospace Applications
Optical sensors are becoming increasingly popular and gradually replacing electrical sensors due to their faster response, higher sensitivity, immunity to electromagnetic interference and electrical sparking. The advancements ... -
Role of PdtaS-PdtaR two component signalling system in metabolic adaptation in Mycobacterium spp.
The ability to perceive and adapt to environmental fluctuations, both internal and external, is a fundamental characteristic of life across diverse organisms. Within the context of pathogenic bacteria such as Mycobacterium ... -
Developmental Studies on a Multistage Induction Coilgun-Based Electromagnetic Launcher
The archetypal chemical propellant-based launchers (e.g., guns, missiles, spacecraft launchers, etc.) with their hot trailing plume (hence, known as the “hot-launching system”) has been widely deployed over the decades by ... -
Arabian Sea High Salinity Core in the Bay of Bengal
The Summer Monsoon Current (SMC) advects high salinity water from the Arabian Sea into the Bay of Bengal (BoB) during the summer monsoon. This high salinity water subducts and enters the BoB as a subsurface high salinity ... -
Rational Secure Computation: New Definitions and Constructions
Cryptography and Game Theory are two fascinating areas of modern computing, and there have been numerous works since the early 2000s to bridge these. While cryptography provides mechanisms to detect deviations, game theory ... -
Role of the unstructured N-terminal region and interacting proteins on the function of Mycobacterium tuberculosis σA
A distinctive feature of the bacterial RNA polymerase is the modular organization. The core of this enzyme, comprised of a dimer of the α subunit assembles with the β, β', and ω subunit. The core RNA polymerase enzyme ... -
Event-Related Potential Interpretation Approaches for Neonatal Hearing Screening
Biopotentials are the electrical discharges generated from the human body. They reflect the status underlying the phenomenon and are frequently used to assess the real-time physiological status of the human body. ... -
Integration of Drones/Uavs into Indian Civil National Airspace System, Regulatory Framework for Commercial Usage of Drones
Tremendous growth has occurred in drone or unmanned aerial vehicle (UAV) usage in the military and civilian sector over the past several years, and this burgeoning industry brings tremendous potential economic and social ... -
Stable Isotope and Geochemical Approaches for Hydrological Characterization and Estimation of Seasonal Groundwater Inputs in the Humid to Semi-Arid Reach of the Kabini River, South India
In tropical catchments, like the Kabini region of South India, understanding the intricate contributions of baseflow is essential for sustainable water management and ecosystem preservation. Baseflow, which is predominantly ... -
Syntheses and Structural Investigations of Iron(III) Ternary Complexes And Cu(II) Binary Complexes of Nucleotide and its Constituents
Nucleotide is the monomeric unit of DNA and RNA, being the building block of nucleic acid, it plays important roles in many biological processes. For example, Adenosine tri phosphate (ATP) acts as a storage and transporter ... -
Bandit Algorithms: Fairness, Welfare, and Applications in Causal Inference
We study regret in online learning from a welfarist perspective and explore an application of bandit algorithms in causal inference. We introduce Nash regret, which measures the difference between the optimal action ... -
An importance sampling in N Sphere Monte Carlo and its performance analysis for high dimensional integration
Statistical methods for estimating integrals are indispensable when the number of dimensions (parameters) become greater than ~ 10, where numerical methods are unviable in general. Well-known statistical methods like ... -
Effects of 3d Morphological Characteristics of Sand on Multi-scale Intergranular and Sand-geosynthetic Interactions
To understand the process of mobilization of shear strength in sands and sand-geosynthetic interfaces at a fundamental level, it is essential to precisely characterize the size and shape of the grains and the shear-induced ... -
Investigations into a novel process for high ash Indian coal gasification- a two-stage gasifier
India, in addressing climate change, has embarked on clean coal initiatives to reduce carbon emissions. Various measures are taken towards meeting the decarbonization process, and coal conversion through gasification is ... -
Investigating Neural Mechanisms of Word Learning and Speech Perception
Language learning and speech perception are remarkable feats performed by the human brain, involving complex neural mechanisms that allow us to understand and communicate with one another. Unravelling the mysteries of these ... -
Search for Long-Lived Particles at High Luminosity Large Hadron Collider and Beyond
Despite extensive searches, clear indications of new physics beyond the Standard Model (BSM) remain elusive. Traditionally, experimental searches at the Large Hadron Collider (LHC) during Phase I and phenomenological studies ... -
Solid Oxide Based Electrodes for CO2 Reduction
The conversion of CO2 to fuels can be instrumental in reducing future dependence on fossil fuels. High temperature (800oC) electrochemical reduction of CO2 to CO using a solid oxide electrolysis cell (SOEC) provides an ... -
Integrating Computational Tools and Models to Study Positive-sense RNA Virus Lifecycle
Positive-sense single-stranded RNA ((+)RNA) viruses pose significant challenges to public health. Notable families such as Enteroviridae, Flaviviridae, and Coronaviridae have caused epidemics (Dengue, Poliomyelitis, Zika) ... -
Topological Structures and Operators for Bivariate Data Visualization
Understanding complex phenomena in diverse scientific and engineering disciplines often relies on decoding the interplay among real-valued or scalar fields that are measured or computed over a spatial domain. This thesis ... -
