Battle of Bandits: Online Learning from Subsetwise Preferences and Other Structured Feedback
The elicitation and aggregation of preferences is often the key to making better decisions. Be it a perfume company wanting to relaunch their 5 most popular fragrances, a movie recommender system trying to rank the most ... -
Novel Reinforcement Learning Algorithms and Applications to Hybrid Control Design Problems
The thesis is a compilation of two independent works. In the first work, we develop novel weight assignment procedure, which helps us develop several schedule based algorithms. Learning the value function of a given policy ... -
Design and Development of ECA based Routing Protocols for Ubiquitous Network
The ubiquitous network is a heterogeneous wireless network comprising of computing devices such as laptops, smartphones, tablets, PDAs, etc., are connected to any device at any time, anywhere that enabling mobile users to ... -
Towards Effcient Privacy-Preserving Two-Party k-Means Clustering Protocol
Two-party data mining is a win-win game if played with a guarantee of data privacy from each other. This guarantee is provided by the use of cryptographic techniques in designing the two-party protocol. The need to ... -
Resource Allocation Schemes for 4G/5G based Interactive Multimedia Networks
Emerging interactive multimedia applications such as Virtual Reality (VR) and Augmented Reality are upcoming important applications in healthcare, autonomous transport, education, tactile internet, and industrial automation. ... -
Role of Mycobacterium tuberculosis UvrD1 and UvrD2 helicases in resolving G-quadruplex DNA structures
Unresolved G-quadruplex (G4) DNA secondary structures impede DNA replication and can lead to DNA breaks and to genome instability. Helicases are known to unwind G4 structures and thereby facilitate genome duplication. ... -
PP2A-phosphatase and Polo-like kinase 1 regulates spindle positioning by orchestrating the cortical levels of the dynein adaptor NuMA
The mitotic spindle is a microtubule-based diamond shape structure that captures chromosomes and facilitates their segregation during anaphase. Proper positioning of the mitotic spindle is critical for defining the ... -
Physics Based Design & Development of Gallium Nitride High Electron Mobility Transistors (HEMTs) & Schottky Barrier Diodes for Power and RF Applications
Silicon-based transistors such as MOSFETs have been the preferred choice for decades now for both power as well as high-frequency device applications. The meteoric rise of Silicon was fuelled by the quest for a highly ... -
Design and Development of Cryogenic Transfer Lines and Studies on Flow Phenomena
Cryogenics refers to the field of science and engineering below 123 K (-150 ºC). Also it deals with the production, utilization and maintenance of the same. Below 123 K, the so called “Permanent gases” such as Argon, ... -
Layered Metal Dichalcogenides-Based Hybrid Devices for Resistive Sensing
During the past few decades, photodetectors (PDs) are being regarded as the crucial components of many photonic devices which are being used in various important applications. However, the PDs based on the traditional bulk ... -
Shape and Load Estimation using Fiber Bragg Grating Sensors for Structural Health Monitoring of Aircraft Structures
Aerospace structures are exposed to severe loading and environmental conditions, which necessitates constant inspection and maintenance to improve safety and reliability. Currently, the aerospace industry largely depends ... -
Study of Structure and Dynamics of Bioactive Natural and Synthetic Peptides by NMR Spectroscopy and In silico Methods.
The thesis covers conformational analysis of several bioactive peptides using solution and solid-state NMR along with in silico analysis of some of them compiled in five chapters. It starts with an introduction to solution ... -
Subsonic, turbulent, round and plane, twin jets
Multiple jets appear in many engineering applications such as engines of launch vehicles and aircraft, fuel injectors and other mixing devices. Twin jets are models to understand the differences from single jets that can ... -
Collective escape dynamics of fission-fusion groups in the wild
Collective movement is a fundamental process affecting the survival and reproductive success of group-living animals. Many of the hypothesized benefits of grouping such as predation evasion and foraging efficiency may ... -
Enhancing Blockchain Implementations
Blockchain technology elegantly provides a spectrum of desirable semantic properties, including immutability, authenticity, verifiability, and data integrity. In recent years, implementing blockchains on relational database ... -
Structural and DNA binding properties of ARID domains present in hSWI/SNF chromatin remodeling complex subunits
The SWI/SNF complexes are multisubunit-containing protein complexes that are involved in chromatin-remodeling processes in the eukaryotic cells. In higher eukaryotes, SWI/SNF complexes contain one or more mutually exclusive ... -
Mechanistic Insights for Controlling Electromagnetic Interference Shielding Through Microwave Absorption in Magnetic Composites
Extensive use of electronic devices in daily communication and information technology causes high (microwave) frequency electromagnetic interference (EMI). This EMI often leads to noise, data misinterpretation or malfunctioning ... -
