Additive Manufacturing of Inconel 718 Cellular Structures
Additive Manufacturing (AM) is getting adopted in various industries like automobile, aerospace, medical, nuclear, defense, and space, amongst many others, in the last five to ten years due to the tremendous advantages of ... -
Investigations on structural, optical and electrical properties of lattice matching CdZnTe & HgCdTe colloidal quantum dot systems for possible core-shell structures in optoelectronic devices
In this work, alloyed II-VI group CdZnTe, HgCdTe colloidal quantum dots (QDs) have been synthesised and their optical, material, electrical properties are studied for optoelectronic applications. The bandgap of the alloyed ... -
Identification and Biochemical Characterization of Novel Inhibitors of Nonhomologous End Joining: Implications in DNA Double-Strand Break Repair and Cancer Therapy
To summarize, in the present study, we have synthesized and characterized three novel NHEJ inhibitors targeting DNA Ligase IV, with several fold better efficacy compared to SCR7 and thus potential to be developed as cancer ... -
Two-temperature thermodynamics and continuum modelling of viscoplaticity in metals
In recent years, numerous studies have shown the complexity of plastic deformation in metals. The accuracy in modelling inelastic behaviour holds great significance for engineers as metals and metallic alloys are extensively ... -
Knowledge-driven training of deep models for better reconstruction and recognition
This thesis aims to efficiently solve many interesting and challenging problems by incorporating appropriate image processing techniques in a deep learning framework. We have proposed, implemented and tested efficient ... -
Speech enhancement using deep mixture of experts
Speech enhancement is at the heart of many applications such as speech com- munication, automatic speech recognition, hearing aids etc. In this work, we consider the speech enhancement under the framework of multiple ... -
Binaural Source Localization using subband reliability and interaural time difference patterns
Machine localization of sound sources is necessary for a wide range of appli- cations, including human-robot interaction, surveillance and hearing aids. Robot sound localization algorithms have been proposed using ... -
Tuning the electrical and thermoelectric properties of bilayer graphene by band engineering
Graphene and its two dimensional (2D) analogues have sustained the interests of the researchers for quite some time because of the rich physics they offer including many quantum phenomena and non-trivial topological ... -
Dynamics of a Stratified Population of Optimum Seeking Agents on a Network
Very large scale multi-agent systems occur both naturally and in engineering applications. In many of these systems, the agents are either selfish or act with varying levels of coordination. Understanding the evolution of ... -
Temporal patterns of neural activity governing spatial representation in the hippocampus
Space is a fundamental substrate for animal interactions with the external world. The hippocampus, a region deep within the temporal lobe of mammalian brains, is a multisensory structure that has been heavily implicated ... -
Network models uncover key molecular perturbations in complex human diseases
Biological systems are complex networks of molecular components that function in a tightly controlled manner. Any form of perturbation in these components or their associated interactions affects the normal physiology of ... -
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, ...
