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 ... -
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 ... -
Experimental And Analytical Investigations Into Development Of Double-Tuned Expansion Chambers And Extended Concentric Tube Resonators
(2011-07-08)The performance of an acoustic filter (or muffler) is measured in terms of one of the following parameters: Insertion Loss (IL), Level difference (LD) and Transmission loss (TL). All these three parameters may be evaluated ... -
Experimental and Analytical Studies on Damage Detection and Failure Analysis of Transmission Towers and Tower like Structures
(2017-12-07)The transmission line (TL) tower is an important component in electrical network system. These towers consist of members (angle sections) and connections (bolted connections) plus foundation, which act together to resist ... -
Experimental and computational approaches to understand collective behaviors of bacterial pathogen Pseudomonas aeruginosa
Pseudomonas aeruginosa is a Gram-negative opportunistic pathogen, estimated to account for 15-20% of hospital-acquired infection-related deaths around the globe in a year. This bacterium exhibits two distinct collective ... -
