Development of an Intraoperative Probe for Brain Tumour Delineation Combining Multimodal Tissue Characterization and Soft-Robotics
Accurate identification of surgical margins in brain tumors is of significant prognostic importance. Despite the availability of 5-ALA and image guidance methods, recognizing tumor boundaries is highly subjective, dependent ... -
Barrier Function Inspired Reward Shaping in Reinforcement Learning
Reinforcement Learning (RL) has progressed from simple control tasks to complex real-world challenges with large state spaces. During initial iterations of training in most Reinforcement Learning (RL) algorithms, agents ... -
Spectral Efficiency and Energy-efficiency Trade-off in Spectrum Sharing and RIS-based Wireless Systems
Spectral efficiency (SE) and energy-efficiency (EE) are the two key performance indicators for next-generation wireless systems. The SE specifies how much information can be communicated by the system per unit time and ... -
Design and Optimization of Cell-Free Systems: Channel Estimation, Duplexing Scheme, and Synchronization
Cell-free massive multiple-input multiple-output (CF-mMIMO) systems, where multiple access points (APs) jointly and coherently serve a large number of user-equipments (UEs) in a geographical area, offer multi-fold improvement ... -
First-principles Based Investigation of the Adsorption and Optoelectronic Properties of Polymorphic Borophene
The discovery of graphene has prompted interest in other two-dimensional materials, especially borophene, which is a single layer of boron atoms that forms a variety of crystal shapes. Borophene, the lightest member of the ... -
Frequent Episode Mining: Efficient Discovery Algorithms and Significance Analysis
Frequent Pattern mining is a popular area of data mining, where the goal is to unearth interesting patterns that occur often in a given data. A pattern is a local structure that captures correlations and dependencies present ... -
Estimation of flashovers in the EHV/UHV lines on the east coast due to lightning produced by the Bay of Bengal cyclones
Electric Power is imperative for the modern world. The quality and reliability of the power supply can be impaired by several factors. Lightning is one such natural threat that disrupts the continuity of supply and can ... -
Audio-Visual association learning in Humans and Multimodal Networks
We easily learn audiovisual associations when we give visual objects their names. While humans easily learn the names of new objects while retaining previously learned information, deep neural networks forget old ... -
Exploring Fairness and Causality in Online Decision-Making
Online decision-making under uncertainty is a fundamental aspect of numerous real-world problems across various domains, including online resource allocation, crowd-sourcing, and online advertising. Multi-Armed Bandits ... -
Design and Development of Optical Modality-based Probe for Breast Cancer Diagnosis
Breast Cancer is the leading cause of mortality among women worldwide. The key to efficiently controlling cancer on a larger scale is effective diagnosis at an early stage by distinguishing the vital signatures of the ... -
Automatic Speech Recognition Solutions For Resource Constrained Devices
The current realm of Automatic Speech Recognition (ASR) systems, pivotal in applications ranging from voice assistants to transcription services and assistive technologies, requires an improvement when confronted with ... -
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 ... -
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 ... -
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. ... -
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 ... -
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 ... -
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 ... -
Integrated Photonic Devices in Near-IR to Mid-IR for Agricultural and Environmental Sensing Applications
Near to mid infrared (NIR-MIR) chemical sensing is a remarkably influential analytical technique that capitalizes on the interaction between matter and infrared radiation within a specific wavelength range. Predominantly ... -
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 ... -
