Localization methods for correlated spatially distributed sources
Modeling of sources as point in nature is a very idealistic modeling in array processing. There have been a number of distributed source models proposed in the literature. This work is based on one of these models. It tries ... -
Studies on methods of reducing some cost parameters in microprogrammed digital computers and distributed processing systems
The concept of microprogramming is frequently employed in designing the control units of modern digital computers and microprocessors. In a microprogrammed digital computer, the size of control memory depends upon the width ... -
Signal Processing Algorithms for Target Parameter Estimation in a Dual-Function Radar Communication System
In next-generation technologies, the demand for higher performance in fields such as radar and communications is driving the use of higher frequencies, leading to spectrum congestion. A promising solution to this challenge ... -
Proximity engineering of correlated states in graphene heterostructures
Strong electronic correlations are central to many phenomena in condensed matter physics, including unconventional superconductivity, the fractional quantum Hall effect, nematicity, and non-Fermi liquid behavior. In ... -
Improvements on hadronic form factors using analyticity and unitarity constraints
Form factors are of central importance in strong interaction dynamics. While electromagnetic form factors are an important source of information about the internal structure of hadrons, the knowledge of the weak transition ... -
The Seasonal ENSO Transition Mode of the Southern Hemisphere: Definition, Characteristics and Impact
Decadal climate variability (DCV) exerts a profound influence on the global climate system by shaping background oceanic and atmospheric conditions. It drives long-term changes in sea surface temperatures (SSTs), monsoon ... -
Morse Potential Based Aggregation in Multiagent Systems with Applications to Circumnavigation and Exploration
Swarms of autonomous vehicles, which are modeled as Multi-agent systems (MASs), have found increasing applications in search and rescue, reconnaissance missions, collaborative transportation, among many other applications ... -
A framework for timing analysis of event-driven applications
Event-driven applications, particularly those based on the publish–subscribe communication model are widely adopted to build responsive and decoupled applications in domains such as robotics, the Internet of Things ... -
Formation Mechanism, Structure and Optical properties of Functional Nanoparticle Assemblies
Metal nanoparticles (MNPs) concentrate light near their surface because of localized surface plasmon resonances (LSPR). LSPRs depend on MNP morphology, composition, size, and the metal–dielectric interface. LSPRs are further ... -
Decongestion Strategies for Dense Urban Airspace
With the rapid growth in the number of uncrewed aircraft systems (UAS) being deployed for on-demand delivery applications, severe congestion is anticipated in the low-altitude class-G urban airspace. Thus, there is a need ... -
A Few Probable Electrolyte and Electrode Design Strategies for Multivalent-Ion-Based Rechargeable Batteries
Lithium-ion batteries have transformed modern energy storage, but their limitations concerning the materials supply chain and safety risks highlight the need for alternative technologies. This PhD thesis explores multivalent ... -
Curvature Generation in Self-Assembled Fluid Membranes
The ability of thin sheets to curve into complex three-dimensional shapes underlies diverse biological processes. We study curvature generation in fluidic membranes using the model system colloidal membrane, which is ... -
Character Recognition Using Optical Correlation
A study of effect of rotation and lateral displacement on the correlation outputs when two characters are correlated optically (Taking numerals as characters) has been carried out. Thus, the feasibility of optical correlation ... -
Dynamic Channel Allocation for integrated Voice Data Communication A Tdm Approach
Integrated Services Digital Network (ISDN) is an extension of conventional telecommunications and the data trafics like text, facsimile, image. Efficient transmission of voice/data on a common communication channel has ... -
Mechanics of Flat-punch Indentation of Metallic Honeycombs Using High-fidelity Continuum FE Simulations
Metallic honeycombs and foams are widely used in the automotive and aerospace industries due to their desirable mechanical properties such as light-weight, high and tailorable specific stiffness, high specific strength, ... -
Evaluation of Air Blast Swirl Injector: Flow-Field Hybrid RANS-LES Studies And Coupling With RANS Spray Characterization Colligating Global Combustor Characteristics-A Novel Exploration
The injector plays a critical role in combustion efficiency, flame stability, ignition, and combustor exit profile. The protocol of designing future engines meeting the requirements of lower emissions, noise, and the use ... -
Photoluminescent Lanthanocholate Gel-Based Sensors for Human Well-Being
Lanthanide-based luminescent materials have emerged as highly promising in biosensing, primarily owing to the long lifetimes of lanthanides, which enable the efficient elimination of background signals during time-delayed ... -
Immunogen design to enhance Influenza and SARS-CoV-2 vaccine efficacy
Influenza and SARS-CoV-2 are pleomorphic viruses that cause respiratory diseases in humans and present significant public health threats. Vaccination has been essential in controlling the spread of these infections and ... -
Photo-physical Investigation of Bistable Molecular Magnetic Materials: Design, Synthesis and Applications
The work reported in this thesis is structured around four interconnected studies that explore distinct, yet interrelated facets of molecular magnetism. An overview of the chapters presented in this thesis is outlined ... -
Activation of H–E (E = H, Si, B, C) σ-Bond by Iridium and Rhodium Pincer Complexes: Implications in Catalytic (De)hydrogenation Reactions
Methane is a major constituent of natural gas and crude oil. Due to its abundance, methane is attractive from the standpoint of its utilization and conversion into value-added products.1 This process involves activation ...
