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 ... -
