Space-time variability of near-surface salinity in the Bay of Bengal
Freshwater from monsoon rain and rivers leads to a 5-10 m deep low-salinity layer in the north Bay of Bengal from August to February. The thin fresh layer, with strong stratification at its base, is highly responsive to ...
Fabrication and Characterization of Optomechanical Devices
Silicon photonics is a promising platform for photonic devices and circuits, largely driven by advanced complementary metal-oxide-semiconductor (CMOS) processing technology. An extremely crucial component for a photonic ...
Analysis of Kinematic Constraints in Fixed-Wing UAV Formation Flying
Rise in autonomy has led to increase in usage of Unmanned Aerial Vehicles (UAVs) for various applications and has allowed the UAVs to perform complex and hazardous missions with ease. Formation of multiple UAVs finds ...
Physical controls of chlorophyll distribution in the North Indian Ocean
The north Indian Ocean is one of the highly productive regions among the tropical oceans.
Being a prominent monsoon regime, the basin exists as a highly dynamic region charac-
terised by intense mixing and upwelling and ...
Rheology of Dense Granular Chute Flows
Granular flows have always fascinated researchers through its complex and mysterious behavior. Although a collection of solids, they exhibit properties like that of fluids. Flows over an inclined plane, known as chute flow, ...
Development and Characterization of Ordered Magnetic Nanocomposite
Magnetic nano-particles dispersed in a non-magnetic matrix is promising for storage technology. Additionally, such magnetic nano composite (MNC) materials have potential applications in the field of telecommunication, ...
Syngas Production by Methane Reforming and H2 Purification by CO Abatement over Transition Metal-Substituted Reducible Oxides
Methane and carbon dioxide are two major greenhouse gases, with CH4 having higher potency towards global warming. Several methods have been explored for transforming CH4 into higher value products, of which syngas production ...
Kinematic Design and Optimal Synthesis of Parallel Manipulators Using Monte Carlo Method
Parallel manipulators are widely used for a variety of tasks where increased accuracy and large load carrying capacities are required. In this work, we propose a Monte Carlo based method to represent and quantify the ...
Study of Solvent Induced Crystal Polymorphism via Molecular Simulations of Crystal Nucleation
The ability of a compound to exist in different crystal structures is called crystal polymorphism
and such crystals of varied spatial arrangement are called polymorphs. The polymorphic forms
can differ in their properties ...
Resonances and beats in nonlinear structural acoustic waveguides
In this thesis that is entirely analytical in nature, nonlinear wave propagation in various structural-acoustic waveguide geometries is studied. The waveguides considered include a circular cylindrical waveguide with a ...
