Multimedia Streaming and Proxy Caching
The information technology revolution has led to the explosive growth of the Internet. There is an increased demand for real-time applications like audio/video streaming and videoconferencing. The increase in demand ... -
Neighborhood based algorithms for network problems
This thesis presents novel techniques for designing efficient algorithms to solve various graph problems, with a focus on both sequential and parallel computation models. The key contributions include: An O(dm)O(dm)O(dm) ... -
Lexicalisation of montague semantics: a unified approach to semantic interpretation
This thesis presents the X/LTAG model, a novel framework for semantic representation that integrates the Lexicalized Tree Adjoining Grammar (LTAG) formalism of Arvind Joshi with the possible world semantics of Richard ... -
A New Framework for Reconstructing One-and Multi-Dimensional Signals from Partial Information
This thesis addresses a class of inverse problems in signal and image reconstruction using partial information such as zero crossings, Fourier sign data, extrema, and modulus maxima. The focus is on reconstructing images ... -
Estimating probabilities of rare events in regenerative systems via importance sampling
In the high-speed networks currently being designed, the probability of packet loss required is very low, while the closed-form expressions for these events are usually not available. Therefore, one needs to estimate these ... -
Discrete electron fluctuations in van der Waals heterojunction
Two-dimensional (2D) materials, including transition metal dichalcogenides (TMDs) and graphene have emerged as promising candidates for next-generation nanoelectronic devices due to their atomically thin geometry. This low ... -
Herglotz representation, approximation by inner functions, and Hankel operators
This thesis can be broadly categorized under the theories of multi-variable operators and holomorphic functions, structured into two distinct parts. The first part investigates the relationship between two classical theorems: ... -
Development of Fully Printed Smart Tags with On-chip Power Sources
Within the last two decades, the field of printed and flexible electronics has matured to the level that complex solutions to societal needs can be envisioned. This includes applications involving multi-sensor platforms, ... -
Flood Risk Assessment in Peninsular India: Integrating Data, Multivariate Statistics, and Machine Learning
Floods are among the most significant natural hazards in India; however, their drivers, spatial coherence, and potential impacts remain poorly understood, particularly in data-scarce catchments. This thesis addresses these ... -
Learning Action Priors for Deep Visual Predictions
This thesis addresses the critical challenge of visual prediction in mobile robotics, particularly focusing on scenarios where cameras mounted on autonomous robots must navigate dynamic environments with human presence. ... -
Pockels effect based on-chip Electro-optic modulators using ferroelectric materials
An electro-optic modulator finds applications in multiple technological fields like optical communication, photonic computing, quantum computing, signal processing, neuromorphic computing, programmable photonics, and optical ... -
Correlation Between Microstructure, Electrochemical Degradation and Hydrogen Permeation behaviour of Electrodeposited Cobalt Based Coatings
The application of cobalt and cobalt based coatings is limited by their electrochemical degradation in corrosive environments. In the present work, corrosion and hydrogen permeation behavior of electrodeposited Co and ... -
Deciphering the role of miR-631 in the pathogenesis of oral squamous cell carcinoma
Oral squamous cell carcinoma (OSCC) is a malignant neoplasm originating from the epithelial cells of the oral cavity. The Asian population has the highest incidence of OSCC and despite advances in its treatment, the five-year ... -
Enzymatically Combating Biofilm Associated Microbial Infections: Towards Next-Gen Enzyme-Based Therapeutics
Bacteria employ various defense mechanisms, one of the most significant being forming biofilms─structured communities of microorganisms encased in a self-produced extracellular polymeric substance (EPS) matrix. The widespread ... -
Investigation of the Indian Summer Monsoon Rainfall Using Statistical and Machine Learning Techniques
The Indian Summer Monsoon is an important atmospheric phenomenon, marked by a characteristic seasonal wind reversal pattern, delivering 70 to 90% of the annual rainfall to the Indian subcontinent. Monsoon rain profoundly ... -
Exploration of Oxides and Polyanionic Cathodes for Zn-ion and Zn-air Batteries
Lithium-ion batteries (LIBs) rule the modern consumer electronics and electric vehicle sectors. However, their high production costs, safety risks from flammable electrolytes, and paucity of lithium resources have spurred ... -
Optical edge defection based image segementation algorithms
The work reported in this thesis primarily addresses edge detection algorithms in noisy images. The subjective errors that are inevitable in preprocessing and postprocessing generally used in edge detection cause errors ... -
Algorithms for testing planarity of chordal graphs and hamiltonicity of planar chordal graphs.
Design and analysis of graph algorithms is an active research area in Computer Science. Designing efficient algorithms for graph problems is both challenging and rewarding from the point of view of theory and applications. ... -
Pattern recognition schemes involving feature measurment and random classification costs
The central theme of this thesis is the study of the effects of costs on the design and operation of statistical pattern recognition schemes. An analysis of Bayesian pattern recognition including feature measurement costs ... -
A protocol for the Bi-directional connectivity of peers in the presence of heterogeneous internet address space
The number of hosts connecting to the Internet is growing day by day, and the available statistics show that this growth is exponential. This growth has made IP address a scarce resource. IPv6 is proposed as a long term ...
