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 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 ... -
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 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 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. ... -
Expanding The Horizon Of Mycobacterial Stress Response : Discovery Of A Second (P)PPGPP Synthetase In Mycobacterium Smegmatis
(2015-12-21)The stringent response is a highly conserved physiological response mounted by bacteria under stress (Ojha and Chatterji, 2001; Magnusson et al., 2005; Srivatsan and Wang, 2007; Potrykus and Cashel, 2008). Until recently, ... -
Expanding the Possibilities of Multifunctional Gelatin Methacrylol Bioinks for 3D Bioprinting of Complex Biomimetic Tissue Constructs
Tissue engineering, or the construction of complex tissue-like structures for injured tissue replacement and regeneration, has been a subject of investigation over the last thirty years. In the last decade, there has been ... -
Experience Mapping based Prediction Controller
(2018-08-13)A novel controller termed as Experience Mapping based Prediction Controller (EMPC) is developed in this work. EMPC is developed utilizing the broad control concepts of human motor control (HMC). The concepts of HMC are ... -
Experiences in using Reinforcement Learning for Directed Fuzzing
Directed testing is a technique to analyze user-specified target locations in the program. It reduces the time and effort of developers by excluding irrelevant parts of the program from testing and focusing on reaching ... -
Experiential Sampling For Object Detection In Video
(2010-08-26)The problem of object detection deals with determining whether an instance of a given class of object is present or not. There are robust, supervised learning based algorithms available for object detection in an image. ... -
Experimental Analysis of Shock Stand off Distance over Spherical Bodies in Hypersonic Flows
(2018-07-18)One of the characteristics of the high speed ows over blunt bodies is the detached shock formed in front of the body. The distance of the shock from the stagnation point measured along the stagnation streamline is termed ...
