Evolutionary Aspects of Archean Kolli-Massif, Southern India : An Archive of Crustal Processes
(2018-08-13)The continental crust is the record of the history of the Earth, of the processes and events that have contributed to the planet's evolution. It is now understood that the continental crust is growing continuously since ... -
Evolutionary Design Of Active Site Plasticity In R.KpnI For Promiscuity In Metal Ion Utilization And Substrate Recognition
(2013-03-27)Restriction modification (R-M) systems are important components of the prokaryotic arsenal against invading genomes. R-M systems directly target the foreign DNA and are often considered as primitive immune systems in ... -
Evolutionary design of plan based pattern recognition systems in complex domains
Many real-life Pattern Recognition (PR) problems do not fit into the classical PR paradigms. Such systems are currently being implemented using knowledge-based approaches. Designing such systems is an involved, evolutionary ... -
Evolutionary Optimization For Vibration Analysis And Control
(2014-03-03)Problems in the control and identification of structural dynamic systems can lead to multimodal optimization problems, which are difficult to solve using classical gradient based methods. In this work, optimization problems ... -
Exact analytic solutions for some classes of partial differential equations
Exact solutions of linear partial differential equations with variable coefficients and those of nonlinear partial differential equations are dilEcult to obtain. The present thesis attempts to extend the existing methods ... -
Examining Climatic Response, Vulnerability and Adaptation in Rural Indian Dwellings to Climate Change: Case studies in three climatic zones
Buildings have evolved traditionally based on local resources and skills. They predominantly relied on passive climate-response mechanisms to provide indoor comfort. However, contemporary buildings, made primarily of bricks, ... -
Exchange Spring Behaviour in Magnetic Oxides
(2018-02-23)When a permanent magnet is considered for an application, the quantity that quantifies the usability of that material is the magnetic energy product (BH)max. In today’s world, rare earth transition metal permanent magnets ... -
Excitation dynamics in GaAs quantum wells
The dynamics of excitons is studied using time?resolved photoluminescence. We deduce experimentally, for the first time, the intrinsic homogeneous linewidth of free excitons in GaAs quantum wells. The scattering rate of ... -
Excitation Energy Transfer In Donor-Acceptor Systems Involving Metal Nanoparticles, And In Conjugated Polymers
(2013-02-19)This thesis consists of two parts and nine chapters. The first part (Part I) presents theoretical studies on non-radiative mode of excitation energy transfer (EET) in donor-acceptor (D-A) systems involving metal nanoparticles. ... -
Excited state behaviour of a,b – unsaturated thiones
The thesis entitled “Excited State Behaviour of ?,?-Unsaturated Thiones” consists of six chapters. Chapter I provides a brief introduction to the work presented in this thesis. Chapters II–V describe the photophysical and ... -
Excited state behaviour of substituted cyclopropenethiones and thioketenes and photochemical investigations in cyclodextrins
The thesis entitled “Excited State Behaviour of Substituted Cyclopropenethiones and Oxyketenes and Photochemical Investigations in Cyclodextrins” is divided into three parts. Part A deals with the strain?assisted ??cleavage ... -
Excited State Intramolecular Charge Transfer: Ultrafast Electronic and Vibrational Spectroscopic Study
This thesis incorporates the understanding of the ultrafast excited state photoinduced intramolecular charge transfer (ICT) process in liquid phase. The molecular systems are studied by employing Ultrafast Raman Loss ... -
Excitonic complexes in semiconducting monolayers and their twisted heterojunctions
Monolayers of transition metal dichalcogenides (TMDCs) host excitons, a bound state of electron and hole. Excitonic many-body complexes dominate the optical spectra obtained from this system and manipulating these complexes ... -
Excitons in monolayer transition metal dichalcogenides
Excitons are quasiparticles formed due to electrostatic attraction between the electrons and the holes in a semiconductor. This Coulomb attraction is very strong in the mono- layers of Transition Metal Dichalcogenides ... -
Excursions in ill condensed quantum matter from amorphous topological insulators to fractional spins
Condensed matter physics is a fascinating subject where collective properties of many particle systems show exotic emergent phenomena, practically unpredictable from the behavior of individual constituents. Many basic ... -
Existence and implications of positively curved metrics on holomorphic vector bundles
This thesis is divided into two parts. In the first part, we study interpolating and uniformly flat hypersurfaces in complex Euclidean space. The study of interpolation and sampling in the Bargmann-Fock spaces on the complex ... -
Exotic eutectic microstructures
Solidification of eutectic systems delivers compelling examples of microstructure formation, which makes the phenomena intriguing to many engineers and scientists. Therefore, eutectic solidification is extensively studied ... -
Expanders in Arithmetic Circuit Lower Bound : Towards a Separation Between ROABPs and Multilinear Depth 3 Circuits
Consider the problem of Polynomial Identity Testing(PIT): we are given an arithmetic circuit computing a multivariate polynomial over some eld and we have to determine whether that polynomial is identically zero or not. ...
