Design, Development and Validation of High Performance Fiber Bragg Grating Accelerometers
Fiber Bragg grating (FBG) accelerometers have attracted the attention of researchers as an efficient and attractive alternative to conventional electrical accelerometers. They exploit the remarkable sensing capabilities ...
Morphology and topology of cosmological fields during the Epoch of Reionization
In this thesis we have introduced a real space morphological tool, Contour Minkowski
tensor (CMT) to analyse the 21cm brightness temperature field from EoR. We showed that
the size and shape information of structures ...
Geometrical and Topological Properties of CMB Polarization Fields
Cosmic Microwave Background (CMB) is a relic from the early Universe. It was generated due to the physical processes in the early Universe during an epoch known as the recombination or decoupling epoch. The CMB has highly ...
Numerical studies of shock oscillations and MRI turbulence in accretion
In this thesis, we study two different aspects of accretion flows- (i) quasi-periodic oscillations
(QPOs) seen in the light curves of X-ray binaries as a possible consequence of shock oscillations,
(ii) global 3D ideal ...
Study of the Thermoelectric Properties of RxCo4Sb12 (R=In, Ba) with InSb/GaSb Nano Inclusions
Almost 80% of the world’s energy needs depend on oil, coal and natural gases. Use of natural gases, fossil fuels emit a large amount of CO2 to the earth’s atmosphere, which causes the greenhouse effect and results in an ...
Effect of a fast flux line on the coherence of 3D transmon qubits
With the development of the science and technology, the quantum computers are becoming
the possible key to reveal new breakthroughs. Unlike the classical computers, where we
have classical bits (0or1), in quantum computation ...
On the Kobayashi geometry of domains
In this thesis we study questions broadly related to the Kobayashi (pseudo)distance and (pseudo)metric on domains in ℂn. Specifically, we study the following subjects:
Estimates for holomorphic images of subsets in convex ...
Study of Exciton Dynamics in MoS2 Monolayer and MoS2-QD Heterostructure
The recent studies of two-dimensional semiconductors (2D) and their hybrid structure with zero-dimensional (0D) semiconductors have led to discovering of many fascinating properties that are absent in their bulk counterparts. ...
Studies on Single Step Deposition of ZnO Nanostructured Thin Films for Sensing and Photocatalysis Application
ZnO, band gap of ~3.37eV, is a chemical stable, biocompatiable, non-toxic n-type semiconductor material. Due to advancement of microfabrication technology and chemical synthesis method, nanostructured ZnO are found to be ...
Force and Shape Estimation using Fiber Bragg Grating Sensors for Assistance in Minimally Invasive Diagnostic and Surgical Procedures
Fiber Bragg Grating (FBG) sensors have become increasingly popular for applications in biomedical engineering. Amongst these, use of FBGs in ‘smart instruments’ for minimally invasive diagnostic and surgical procedures ...
