Raman Study of gated devices in two-dimensional materials and pressure effects
This thesis presents Raman study of 2D materials of contemporary interests: 2H-MoTe_2, type-II Weyl semimetal (T_d-MoTe_2), structurally anisotropic semiconductors (1T'-ReX_2 (X=S, Se)) and Mott insulator (FePS_3) under ... -
Designing Solutions to Counter the Attacks in Mobile Ad hoc Networks
The open medium, dynamic topology and distributed operation in Mobile Ad hoc Networks (MANET) leads to high risks. Many solutions are proposed to protect a MANET from attacks, ranging from attack identification to ... -
Architecting Conjugated Molecules for Band Gap Engineering & Photostability
Organic photovoltaic (OPV) modules are flexible, light weight, transparent and thin compared to other emerging photovoltaic technologies, making them well-suited for applications ranging from solar windows to fabrics. A ... -
Reconfigurable Accelerator for High Performance Application Kernels
Accelerating high performance computing (HPC) applications such as dense linear al- gebra solvers, mesh computations, stencil computations requires exploiting parallelism that is resident in loops. Typically these loops ... -
Conductance Fluctuations in High-mobility Graphene Field Effect Transistors
In the past decade, a major fraction of the research carried out in condensed matter physics has been dedicated to address the unique physical properties of single layer graphene (SLG). Different properties of Dirac ... -
Charge Transport in Molecular Systems
Understanding charge transport in molecular systems is of fundamental interest in rapidly growing field of molecular electronics as well as to understand biological signal transfer processes which are accompanied by the ... -
Reliable and Efficient Application Scheduling on Edge, Fog and Cloud
Cloud computing has emerged in the last decade as a popular distributed computing service offered by commercial providers. Public Clouds offer pay-as-you-go access to elastic resources that can be acquired and released ... -
Electromagnetic interference shielding materials derived from epoxy based nanocomposites
The thesis entitled “EMI shielding materials derived from epoxy based nanocomposites” systematically studies the effect of CF and surface modified CF on the EMI shielding of epoxy composites. In addition, to target the ... -
Flow and Forces on Rigid and Flexible Plates in Unsteady Rotational Motion
The swimming motion of fishes have long fascinated scientists and engineers. Over the past few decades, researchers have studied physical models mimicking the tail beat of fishes in an effort to extract key physical ... -
Design, Development, Deployment and Performance Evaluation of Pyroelectric Infra-Red and Optical Camera based Intrusion Detection Systems in an Outdoor Setting
The primary contribution of this thesis is the comprehensive design, development, and deployment of a pyroElectric, InfraRed-sensor-based IntruSion classification (EIRIS) platform, along with attendant detection and ... -
Automated Test Generation and Performance Improvement using Dynamic Program Analysis
Software development process consists of various stages like design, implementation, and testing. Since programmers are considerably involved in these stages, their intuition and expertise play a vital role in the success ... -
Altering DNA topology in mycobacteria: impact of perturbation of DNA gyrase on physiology and gene expression
In the current dissertation, efforts have been made to probe the in vivo role of DNA gyrase to determine its importance in the growth, physiology and gene expression in mycobacteria. In this dissertation, the role of DNA ... -
Molecular determinants of self-assembly of the pore forming toxin Cytolysin A
Pore forming toxins (PFTs) belong to a class of bacterial exotoxins that disrupt the biological membrane barrier by formation of nanopores. These toxins are central to the virulence of pathogens such as S. pneumoniae, ... -
Numerical Studies on Plastic Deformation, Notch Sensitivity and Fracture Behavior of Bulk Metallic Glasses and Composites
Bulk metallic glasses (BMGs) exhibit attractive properties such as high strength and resilience. However, they display negligible tensile ductility due to catastrophic crack propagation inside a dominant shear band (SB). ... -
Coded Caching in Multi-access Networks
Caching is a promising technique that can reduce the amount of data transmitted over latency-prone links, effectively trading affordable memory for expensive bandwidth resources. The frequently demanded content is stored ... -
Estimation of the spatial spread of brain signals at multiple scales
Spatial spread of a particular brain signal can be defined as the area of the cortical tissue around the recording electrode that contributes to the electrical activity recorded by the electrode. More specifically, ... -
Biochemical, Genetic and Molecular characterization of TCP3 and TCP4 transcription factors in Arabidopsis thaliana
The TEOSINTE BRANCHED1, CYCLOIDEA, PROLIFERATING CELL FACTORs (TCP) family of proteins consists of plant-specific, non-canonical basic helix-loop-helix transcription factors that perform diverse developmental processes. ... -
Efficient and Resilient Stream Processing in Distributed Shared Environment
Internet of Things (IoT) deployments comprising of sensors and actuators collect observational data and provide continuous streams of data, often called streaming data or fast data. Smart Cities use such IoT technologies ... -
Checking Observational Purity of Procedures
We provide two static analysis approaches(using theorem proving) that check if a given (recursive) procedure behaves as if it were stateless, even when it maintains state in global variables. In other words, we check if ... -
Aβ42-mediated dendritic spine loss in an in-vitro model of Alzheimer’s disease
