Designing Authentication and Privacy Schemes for Ubiquitous Services
Ubiquitous services in ubiquitous environments provide personalized and adaptive services to a user anytime anywhere, by considering the context information such as profile information and history of the users. Ubiquitous ... -
Higgs phenomenology and Dark Matter prospects in MSSM, NMSSM and U(1) extended SM
Particle physics today is at a juncture where all particles predicted within Standard Model (SM) have been discovered at the particle colliders while no particles from the realm of physics beyond the Standard Model (BSM) ... -
Modelling, Optimisation and Control of Photovoltaic Energy Conversion Systems
With growing energy demands of the society and depleting reserves of conventional energy sources, renewable energy is the need of the hour. Out of the various renewable energy sources available, solar photovoltaic (PV) ... -
Fast and Robust Biomedical Image Reconstruction from Nonuniform Samples
We consider the problem of reconstructing images from non-uniformly under-sampled spatial point measurements with emphasis on robustness to noise. The computational methods that deals with this problem are known as ... -
Resin flow in porous preform during VARTM: A theoretical and experimental investigation
In recent times, fiber reinforced polymer (FRP) composites have received enormous attention due to their exhibited improved mechanical properties, lightweight and design flexibility to manufacture large structures as an ... -
Attention-Feedback and Representations in OCR
A Kannada OCR, named Lipi Gnani, has been designed and developed from scratch, with the motivation of it being able to convert printed text or poetry in Kannada script, without any restriction on vocabulary. The training ... -
Development of Support for Assessment of Creativity, Novelty and Requirement Satisfaction in Designing
The topic of this research in this thesis is creativity assessment of solutions developed in the engineering design process as a means of aiding designers to focus their creative effort during the process. Both engineering ... -
Phase Modulated Selective NMR Methods for resolving overlapping spin systems and rapid data acquisition : Application in metabolomics
research work is focused on the development of new fast solution NMR methods for resolving overlapping spin systems and their application to NMR based metabolomics. In this work two new solution NMR pulse sequences are ... -
Moist and Dry Dynamics in Shallow Water and General Circulation Models
Various aspects of dry and moist atmospheric dynamics are explored through systems of varying complexity, ranging from a 2-D shallow water model to a more complex 3-D general circulation model. First, we examine the response ... -
Multi-Dimensional Solid State NMR - Methods Development and Application to Materials
In recent years, the scope of application of solid-state NMR to different areas has been witnessing a significant increase. Primarily, this is due to the possibility of routine use of proton NMR spectroscopy at ultrafast ... -
Functional and structural studies of proteins involved in telomere maintenance
The linear ends of the eukaryotic chromosomes are protected by a specialized nucleoprotein complex known as telomere. Telomeres consist of telomere DNA and telomere DNA binding proteins (known as shelterin complex). The ... -
Recommendations in Complex Networks: Unifying Structure into Random Walk
Making recommendations or predicting links which are likely to exist in the future is one of the central problems in network science and graph mining. In spite of modern state-of- the-art approaches for link prediction, ... -
Emulation of wind turbine and sensorless control of doubly-fed induction generator for wind energy application
Wind energy utilization has been growing at a rapid rate, fuelling research and development in wind turbine – generator systems. Doubly fed induction generator (DFIG) driven by a wind turbine is a commonly used wind energy ... -
Spectrally selective tandem absorbers for photothermal conversion in high temperature solar thermal systems
Solar energy is the inexhaustible and abundant energy resources on the earth which can be a best substitute for the fossil fuels. Over the past couple of decades, all the solar technologies are rising very steadily in two ... -
Synthesis and development of multifunctional carbonaceous nanostructures for magnetic, optical and catalytic applications
Owing to the ease of functionalization, low synthesis-cost and polymorphism, carbonaceous nanostructures such as carbon globules, nanotubes (CNTs) and graphene sheets emerged technologically as one of the most important ... -
Blast Mitigation Strategies for Marine Sandwich Structures
Blast mitigation is being researched from the time of world war II. There were full field blast tests and analytical studies on the performance of monolithic structures to mitigate blast load. Sandwich structures were also ... -
Bubble and conical forms of vortex breakdown in swirling jets
The present study focusses on vortex breakdown (VB), which occurs in axially convected swirling flows and is characterized by the development of an internal stagnation point and regions of reverse flow. VB has been ... -
Mass Transport in Cu-Interlayer-Si Systems under Various Thermo-Electro-Mechanical Excursions
This work falls in general area of the electro-thermo-mechanical driven mass transport in Cu-Si systems, which often finds relevance while accessing reliability issues pertaining to thin film interconnects in microelectronic ... -
An Exploratory Study on Financial Resources, Scaling, and Performance of Social Enterprises in India
The limitations of the government and current economic system deprived socio-economic opportunities to certain sections of the communities. The non-profit sector, expected to fill this gap, has been afflicted with fiscal ... -
Dispersal Patterns and Processes in Littorinid Snails along the Indian Coastline
Dispersal has important ecological and evolutionary consequences for a species. Marine dispersal is unique because of facilitation by ocean currents, where oceanography interacts with species traits and environmental ...
