Automatic speech recognition for low-resource Indian languages
Building good models for automatic speech recognition (ASR) requires large amounts of annotated speech data. Recent advancements in end-to-end speech recognition have aggravated the need for data. However, most Indian ...
Efficient Constructions of Streaming Codes
Streaming codes are a class of erasure codes that operate on a stream of packets and enable recovery of dropped or erased packets under a decoding-delay constraint. The primary focus of this thesis is on providing constructions ...
Coding Schemes for Secure and Reliable DNA-Based Data Storage
In DNA-based data storage, the desired information is encoded into the quaternary
sequence of synthetic DNA molecules, called oligos. We look at secure communication
via information-containing oligos in the usual three-party ...
Opacity and its Trade-offs with Security in Linear Dynamical Systems
Opacity is notion of privacy that is well-studied in computer science and discrete-event systems. In our work, we extend the opacity notion to linear dynamical systems. Opacity describes an eavesdropper’s inability to ...
Index Coding over Noisy Channels and Some Applications
A broadcast channel that is very effective for disseminating common content becomes highly inefficient when the users request different content. To address this inefficiency of the broadcast channel over which a server ...
Reduced Electrolytic Capacitor Based Single-Phase Converters: Topologies, Control, and Stability
Single-phase converters (SPC) find wide applications in different domestic and industrial
appliances, ranging from a few hundred Watts to a few Megawatts. Second-harmonic ripple
filtering is a critical issue in SPCs, for ...
Energy-efficient Hardware and Algorithmic Techniques for Design of Low-power Intelligent Systems
Low-power design techniques involving hardware and algorithms framework are a fundamental challenge of the modern electronic system. The internet connects devices (IoTs) with advanced capabilities in sensing and processing ...
Excitonic complexes in semiconducting monolayers and their twisted heterojunctions
Monolayers of transition metal dichalcogenides (TMDCs) host excitons, a bound state of
electron and hole. Excitonic many-body complexes dominate the optical spectra obtained
from this system and manipulating these complexes ...
Electro-optically Tunable General-Purpose Microwave Photonic Processors: Platforms, Device Analysis, and Auto-routing Algorithms
Photonic Integrated Circuits (PICs) have been primarily developed as application-specific PICs (ASPICs), relying on time-consuming fabrication processes and exhibiting insertion losses between interconnected ASPICs. To ...
Development of High Throughput Intelligent Indoor Optical Wireless Communication Systems
The proliferation of mobile devices in indoor environments has led to insatiable demand for high-speed, high-bandwidth data connectivity. Optical wireless communication (OWC) is seen as a promising technology capable of ...
