Computational mechanisms underlying eye-head coordination
Gaze or eye-head coordination is an ethologically and physiologically important process that directs the visual system to objects of interest. Due to its relative simplicity, it is an ideal system to study multi-effector ... -
Quantum-Safe Identity-Based Signature Scheme in Multivariate Quadratic Setting
Cryptographic techniques are essential for the security of communication in modern society. Today, nearly all public key cryptographic schemes used in practice are based on the two problems of factoring large integers and ... -
Dynamo Action in Rotating and Shearing Flows
Magnetic fields are omnipresent in universe. They play important role in the formation of stars, galaxies and the accretion onto compact objects and the collimation of the relativistic jets of radio galaxies. It is intriguing ... -
Spectrotemporal Processing of Speech Signals Using the Riesz Transform
Speech signals possess a rich time-varying spectral content, which makes their analysis a challenging signal processing problem. Developing methods for accurate speech analysis has a direct impact on applications such as ... -
Probabilistic Forwarding of Coded Packets for Broadcasting over Networks
Motivated by applications in sensor networks and the Internet of Things (IoT), in this dissertation, we consider the problem of energy-efficient broadcasting from a source node in a large dense network. Flooding, as a ... -
Permeability Modeling for Single Scale and Dual Scale Fabrics and its implementation to Fabrics Undergoing Shear
Composites have found applications, right from high-end aerospace structures to naval and land-based structures. These structures are realized by manufacturing processes like, autoclave and vacuum assisted resin transfer ... -
A Syntactic Neural Model For Question Decomposition
Question decomposition along with single-hop Question Answering (QA) system serve as useful modules in developing multi-hop Question Answering systems, mainly because the resulting QA system is interpretable and has been ... -
Enhancing Coverage and Robustness of Database Generators
Generating synthetic databases that capture essential data characteristics of client databases is a common requirement for enterprise database vendors. This need stems from a variety of use-cases, such as application testing ... -
Intelligent Gaze Controlled Interface for Limited Mobility Environment
Eye movement-based Human Computer Interaction (HCI) has become a significant area of research in computer science. The gaze-based computing devices allow a computer to be controlled using only eye movements, which can be ... -
Effect of off-stoichiometry, grain size and chemical substitution on microstructure, global structure, electromechanical and energy storage properties of lead free Na0.5Bi0.5TiO3 (NBT) based piezoceramics
Ferroelectric and piezoelectric materials, especially the polycrystalline ceramics, are promising candidates for application in pressure sensors, actuators, transducers, ultrasonic motors, energy storage capacitors, ... -
Numerical and Experimental Investigation of Mixed-mode Fracture Behavior of Basal Textured Magnesium Alloys
Magnesium alloys are finding tremendous applications in automobile and aerospace industries owing to their low density, high specific strength, good machinability and damping characteristics. However, their structural ... -
Acoustic-Articulatory Mapping: Analysis and Improvements with Neural Network Learning Paradigms
Human speech is one of many acoustic signals we perceive, which carries linguistic and paralinguistic (e.g., speaker identity, emotional state) information. Speech acoustics are produced as a result of different temporally ... -
Rheology of dense granular materials
Granular materials are frequently encountered in our daily lives and are widely used in several industrial processes. Characterising the flow of these materials has always proved challenging due to the lack of simple ... -
Extending Program Analysis Techniques to Web Applications and Distributed Systems
Web-based applications and distributed systems are ubiquitous and indispensable today. These systems use multiple parallel machines for greater functionality, and efficient and reliable computation. At the same time they ... -
Optical and behavioural tools to investigate the neural correlates of learning and memory
Events in our everyday life are encoded as memories that can be consciously recollected and remembered, although our ability to retrieve the specific details associated with these events diminish with time. Such losses ... -
On certain invariant measures for correspondences, their analysis, and an application to recurrence
The aim of this dissertation is to analyse a certain class of dynamically interesting mea- sures arising in holomorphic dynamics that goes beyond the classical framework of maps. We study measures associated with semigroups ... -
Protein-small molecule interactions: Structural insights and applications in computational drug discovery
Deviation from normal healthy conditions, termed as disease, can often be triggered due to the malfunctioning of proteins. Modulating the functions of proteins by administering therapeutic agents (drugs) may alleviate the ... -
Hermitian Metrics and Singular Riemann Surface Foliations
The main aim of this thesis is to understand curvature properties of a given hermitian metric by restricting it to the leaves of a suitable singular Riemann surface foliation. We will specifically consider the complete ... -
Reliability based analysis and design of slopes and tunnels in rock mass
Structures in rock mass such as slopes and tunnels form an important segment in the infrastructure development of a country. Rock mass consists of intact rock matrix with numerous discontinuities that can be represented ... -
Industrial Structure, Productivity, Growth and Inflation: A Study on Interrelationships, Causality and Effects
India is one of the largest and fastest-growing economies in the world. Its growth is supported by the vibrant manufacturing sector which has strong linkages with other sectors. The manufacturing sector plays a pivotal ...
