A non-classical continuum approach to study the fragmentation of brittle solids
In this thesis, a non-local continuum approach coupled with the phase-field theory and Jones-Wilkins-Lee (JWL) equation of state (EOS) is proposed to model and simulate blast-induced fracture in brittle materials. Also, ... -
Non-classical continuum models for solids using peridynamics and gauge theory
This thesis focuses on three areas of nonclassical continuum mechanics of solids. In the first part, we develop a few peridynamics (PD) models and solution strategies for discretized PD equations in the context of the ... -
Non-classical mechanics and thermodynamics for continuum modelling of solids
This thesis dwells upon several aspects of continuum mechanics and thermodynamics to model elastic and inelastic response of solids. Broadly, the work presented may be categorized into two parts{ one focusing on the ... -
Non-contact Breathing and Heartbeat signals monitoring using FMCW radar
Non-contact breathing and heartbeat signals monitoring are the tasks of extracting them without contact sensors. It became even more critical in COVID 19, and hence it is crucial to estimate them correctly. FMCW (Frequency ... -
Non-covalent interactions in Crystals and Heterocycles of Sulphur and Selenium
Hydrogen bonding plays a very important role in the fields of both chemistry and biology. Conventionally it is represented as D-H---A, where D is the donor atom, A is the acceptor atom and H is the hydrogen atom. It has ... -
Non-Dimensional Kinetoelastic Maps for Nonlinear Behavior of Compliant Suspensions
(2018-02-18)Compliant suspensions are often used in micromechanical devices and precision mechanisms as substitutes for kinematic joints. While their small-displacement behavior is easily captured in simple formulae, large-displacement ... -
Non-equilibrium phases, criticality and information scrambling in low-dimensional quantum systems
This thesis contains research works encompassing different areas of quantum condensed matter physics in low dimensions ranging from non-equilibrium phases of matter, quantum criticality in equilibrium systems and quantum ... -
Non-Equilibrium Phenomena in Sheared Soft Matter and Active Granular System
In this thesis, we have studied non-equilibrium phenomena in sheared soft matter systems and in granular active matter. The surfactant systems are driven out of thermal equilibrium by applying external forcing at the ... -
Non-ergodicity in Interacting Quasiperiodic Systems and Disordered Fock Lattice Models
In this thesis, we study different aspects of many body localization in closed quantum systems. Many body localized systems are isolated interacting quantum systems that fail to thermalize on their own (non-ergodic) and ... -
Non-Gaussian Signatures of Inflationary Gauge Fields: Higher-Order Correlations and Associated Soft Theorems
In modern cosmology, the inflationary paradigm offers a natural framework for understanding the large-scale homogeneity and isotropy of our observed universe and the origin of primordial density perturbations. The quantum ... -
Non-intrusive reduced order modeling of dynamical systems with large stochastic dimensions
The work done in this thesis falls under the broad category of computational mechanics. This thesis addresses the computational challenge of high-dimensional regression and interpolation within the framework of a proper ... -
Non-invasive Elastic Property Recovery of Tissue and Tissue-Like Objects from Ultrasound Excited Resonant Modes
This thesis is on non-invasive elastic property measurement of tissue or tissue-mimicking materials through vibro-acoustography and ultrasound assisted diffusing wave spectroscopy (UA-DWS). Towards this, a known force is ... -
Non-Invasive Microwave Hyperthermia
(Indian Institute of Science, 2006-01-18)Presented in this thesis are the following theoretical investigations carried out on the non-invasive microwave hyperthermia of malignant tumours in the human body: Fundamental concepts of electromagnetic wave ... -
Non-Linear Finite Element Analysis Using Strain-Space Plasticity Coupled With Damage
(2011-01-27)The Thesis deals with Strain-Space Plasticity and its implementation in Nonlinear Finite Element frame-work coupled with damage. Conventional Stress-Space Plasticity, though very popular amongst commercial nonlinear FEM ... -
Non-linear Hall Effect in Two- and Three-dimensional Materials
Underpinned by the concept of Berry curvature in band theory, the family of classical and quantized Hall effects are conventionally observed in the linear response regime. A measurable Hall response requires the time-reversal ... -
Non-linear Vibration of Beam Immersed in Fluid
In space launch vehicles with liquid propulsion system, various sub-systems like gas bottles, anti-slosh baffles and fluid lines are placed inside the propellant tanks which become partially filled over time during flight. ... -
Non-Local Continuum Models for Damage in Solids and Delamination of Composites
The focus of the thesis is on developing new damage models for brittle materials and using these to study delamination of composite structures. Chapter 1 gives an introductory literature review in order to motivate the ... -
Non-ohmic conduction electrical switching and magneto-resistance of quasi one-dimensional conductors at high pressures
Electrical switching in the three charge?transfer complexes mtpa?(TCNQ)_x, benzidine–DDQ, and o?tolidine–DDQ has a common origin, and the basic features observed in these complexes are the same. Current–voltage (I–V) ... -
Non-Parametric Clustering of Multivariate Count Data
(2018-05-23)The focus of this thesis is models for non-parametric clustering of multivariate count data. While there has been significant work in Bayesian non-parametric modelling in the last decade, in the context of mixture models ... -
