Development of A Reconfigurable Synchronous Machine Emulation Platform
Studying the dynamic behaviour of non-linear complex power systems in a laboratory is very challenging. Early experimental platforms used micro-alternators to emulate the behaviour of fixed steam and hydro turbine models. ... -
Experimental and Theoretical Investigations on High Voltage Polymeric Insulators
High Voltage Ceramic and glass Insulators have been widely used by various transmission and distribution utilities for several decades across the globe. Recently composite or silicone rubber insulators have evolved and ... -
Auditory Timbre and Spatialisation: Signal Analysis and Perception of Source Widening
In this work, auditory perception of source widening is examined in the context of different source signal timbre. Perception of widening of source or auditory source width (ASW) arises in three cases: (i) In the presence ... -
Wireless Content Centric Networks: Cross Layer Designs for Queueing, Caching, Power Control and Beamforming
Ever increasing user base of social media platforms such as Facebook, Youtube and the Over-the-Top platforms such as Netflix, Prime Video etc., has increased the demand for High Definition Videos/Contents over the Mobile ... -
Fast Methods for Modelling and Simulation of Fully Integrated Voltage Regulators in Microprocessors
Fully Integrated Voltage Regulators (FIVR) have been introduced in the latest generation of high-performance server microprocessors to improve the performance and power efficiency of the processors. FIVR is a switched ... -
Investigations on Generation of Multilevel 24-Sided Polygonal Voltage Space Vector Structures Without Vector Averaging for Variable Speed Drives
Induction motors are mainly powered by two-level inverters in low-voltage, low-power drive applications. For medium and high voltage applications, a conventional two-level inverter needs high voltage rated switches, ... -
Optimal Placement and Traffic Steering of VNFs and Edge Servers using Column Generation in Data Center Networks
Telecom Service Providers (TSPs) were traditionally dependent on physical devices to provide end-to-end communication. The services provided were high quality and stable but low in agility and hardware-dependent. As the ... -
On Plug-and-Play Regularization using Linear Denoisers
The problem of inverting a given measurement model comes up in several computational imaging applications. For example, in CT and MRI, we are required to reconstruct a high-resolution image from incomplete noisy measurements, ... -
Learning Invariants for Verification of Programs and Control Systems
Deductive verification techniques in the style of Floyd and Hoare have the potential to give us concise, compositional, and scalable proofs of the correctness of various kinds of software systems like programs and control ... -
HYDRA: A Dynamic Approach to Database Regeneration
Database software vendors often need to generate synthetic databases for a variety of applications, including (a) Testing database engines and applications, (b) Data masking, (c) Benchmarking, (d) Creating what-if scenarios, ... -
Exploring the Fundamental Limits of Information-Theoretically Secure Key Generation and DNA-Based Data Storage
In this dissertation, we carry out an exploration of the fundamental limits of information-theoretic security in two different settings: multiterminal key agreement and DNA-based data storage. Most of the dissertation ... -
Empirical Studies of Load Generation for Data Center Networks
Data center networks form the backbone for modern Internet giants like Google, Facebook, Microsoft, and Amazon. Such networks consist of a layer of a large number of storage and compute servers connected through two or ... -
Codes With Combined Locality and Regeneration Having Optimal Minimum Distance and Linear Field Size
This thesis presents error correcting codes in the setting of distributed storage. The codes presented in this thesis are optimal with respect to the minimum distance bound and have a finite field size which grows ... -
Characterization and Modelling of Switching Dynamics of SiC MOSFETs
Silicon Carbide MOSFETs (SiC MOSFETs) fall into the class of wide band gap (WBG) power devices. These devices are commercially available in the voltage range of 600-3300V and superior over the state of the art Si insulated ... -
Underwater Acoustic Communications: Algorithms for Delay-Scale Spread Wideband Channels
In wideband wireless communication systems, the relative motion of the transmitter, receiver, or scatterers in the medium causes the Doppler effect, which stretches or compresses the transmitted waveforms, resulting in ... -
Comparative Analysis of Topological Structures
Measuring scientific processes result in a set of scalar functions (scalar fields) which may be related temporally, be part of an ensemble, or unrelated. Overall understanding and visualization of scientific processes ... -
Multi-connectivity for Urllc and Coexistence with Embb in Time-varying and Fading Channels
Ultra-reliable and low latency communications (URLLC) is a novel use case of 5G. It has challenging requirements like such as low block error rates (BLERs) and stringent latency targets. Multi-connectivity, in which multiple ... -
Boolean Functional Synthesis using Gated Continuous Logic Networks
Boolean Functional Synthesis (BFS) is a well-known challenging problem in the domain of automated program synthesis from logical specifications. This problem aims to synthesize a Boolean function that is correct-by-construction ... -
Efficient and Convergent Algorithms for High-Fidelity Hyperspectral Image Fusion
Hyperspectral (HS) imaging refers to acquiring images with hundreds of bands corresponding to different wavelengths of light. HS imaging has a wide range of applications such as remote sensing, industrial inspection, ... -
Non-contact Breathing and Heartbeat signals monitoring using FMCW radar
Non-contact breathing and heartbeat signals monitoring are the tasks of extracting them without contact sensors. It became even more critical in COVID 19, and hence it is crucial to estimate them correctly. FMCW (Frequency ...
