Wave Propagation in Adhesively Bonded Single Lap Joints: Solution of Forward and Inverse Problems
The use of adhesives for bonding composites as well as metals is rapidly increasing since it provides uniform load transfer and is free of stress concentration seen around the drilled holes in bolted or riveted joints. ... -
Scaling Blockchains Using Coding Theory and Verifiable Computing
The issue of scalability has been restricting blockchain from its widespread adoption. The current transaction rate of bitcoin is around seven transactions/second while its size has crossed the 300 GB mark. Although many ... -
Dynamics of glass forming liquids with emphasis on vibrational modes
The potential energy landscape (PEL) description is regarded as one of the fundamental landmarks in the theory of glass transition, which has found wide applications not only in the understanding of disordered materials ... -
Studies on Processed Granulated Blast Furnace Slag as Fine Aggregate in Mortars and Concrete
Fine aggregate is essential for the preparation of mortar and concrete. There are attempts to find alternatives to the river sand as the natural sources for fine aggregates are dwindling. Currently, sand mining from river ... -
Lignin and Extractive Tracing - an Alternative approach to Assess and Predict Biogas Yields and Production Rates among Tropical Biomass Feedstocks
Predicting biogas yields from the composition of biomass feedstocks has been difficult primarily due to the variations found in their chemical composition and structure of lignocellulosics. This study aims at understanding, ... -
Development of high throughput methodologies to isolate stabilized mutants and to identify interfacial residues
When eukaryotic or unstable proteins are overexpressed in bacteria, these often form insoluble aggregates called inclusion bodies (IB). Refolding the proteins from inclusion bodies can be challenging, resulting in low ... -
Industry 4.0 Maturity and Readiness Assessment: A case of a Manufacturing Organization
The manufacturing sector is the economic backbone of a country and has traditionally played a key role in the growth of almost every country in the world. In India, the manufacturing sector contributes 17 percent to the ... -
New Algorithmic and Hardness Results in Learning, Error Correcting Codes and Constraint Satisfaction Problems
Approximation algorithms are a natural way to deal with the intractability barrier that is inherent in many naturally arising computational problems. However, it is often the case that the task of solving the approximation ... -
Design of Curved Aggressive Annular Diffusers
For economical air transportation, aero engines with lower specific fuel consumption, lower emissions and lower noise levels are required. To this end, the use of turbofan engine with high bypass ratio is an option. With ... -
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 ...
