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. ... -
Compositionality of Object Representations in Brains and Machines
Compositionality in object vision can be defined as the principles governing the relationship between whole objects and their constituent attributes. It is known that object information falling on the retina is processed ... -
Blue and Red Shifting H-Bonding in X−H···Y(X=C, O: Y = O, N, S) Complexes: A Gas Phase FTIR and ab initio Study
Regular H-bonding is essential for sustenance of many chemical and biochemical processes and has been investigated thoroughly since its discovery in the 1920’s. However, experimental finding of blue shifting of X-H stretching ... -
A role for the cohesin complex in subtelomeric gene silencing in Saccharomyces cerevisiae
Chromatin is a dynamic structure which reorganizes to support numerous chromosomal processes. Various histone and non-histone proteins are involved in chromatin organization. One such group of non-histone proteins, known ... -
Optimizing Dense Matrix Computations with PolyMage
Linear algebra computations and other arbitrary affine accesses are ubiquitous in applications from domains like scientific computing, digital signal processing (DSP), and deep neural networks. Libraries such as OpenBLAS, ... -
Development of advanced regularization methods to improve photoacoustic tomography
Photoacoustic tomography (PAT) is a scalable imaging modality having huge potential for imaging biological samples at very high depth to resolution ratio, thereby playing pivotal role in the areas of neuroscience, ... -
On Flow Physics of Spinning Samaras
A particular form of winged seed (samara) dispersal technique adopted by nature uses autorotative (unpowered rotation of the wing generating thrust force against gravity) descent; for eg. in Maple and Mahagony trees. ... -
Improving Glioblastoma Management: A Study of Biomarkers, Tumor Microenvironment and Chemoresistance
Glioblastoma (GBM) is an aggressive form of adult brain tumors. The current standard of care includes maximal safe resection followed by concurrent chemo-radiation therapy and adjuvant chemotherapy with temozolomide. ... -
Implications in substrate recognition, catalysis and drug-design Structural basis for neutralization of ribosome-inactivating proteins by their monoclonal antibodies
Cryptic elements of proteins are not visible in unbound structures but become apparent in ligand/substrate-bound structures. These binary states of cryptic elements in protein structures can impact important aspects of ... -
Fabrication, micro-computed tomography based quantitative 3D microstructure evaluation of 3D printed bioceramic scaffolds and FE modelling of biomedical implant prototypes
In summary, this thesis provides the following outcomes: a) Formulation of novel powder-binder combination for 3D powder printing of resorbable bone-tissue scaffold. b) The effect of post-processing approach on the macro ... -
A Study on the Influence of Reduced Electric Field on Plasma Assisted Combustion Kinetics
Plasma assisted combustion (PAC) technology has attracted much attention in the recent years as an innovative technique to improve the combustion efficiency. Plasma can enhance the combustion process mainly through two ... -
Erasure Codes for Distributed Storage: Tight Bounds and Matching Constructions
The reliable storage of Big Data across a spatially distributed network of nodes, calls for erasure-correcting codes that in addition to protecting against data loss, can also efficiently handle node repair. The need for ... -
Upper Frequency Bound on Circuit-Based Models for Transformer Windings
The power generation, transmission and utilisation are necessarily being carried out at different voltage levels, and require transformers for performing the voltage level conversions. As a result, transformers form one ... -
New insights into the role of condensin in Saccharomyces cerevisiae
Structural Maintenance of Chromosomes (SMC) complexes are highly conserved from prokaryotes to eukaryotes. Saccharomyces cerevisiae has six SMC proteins which form three SMC-complexes in association with non-SMC subunits ... -
Molecular Construction Using Carbene and Diboron Systems: Catalytic Transformation of C-C and C-Hetero Atom Bonds
The thesis presents an unconventional approach for the molecular construction using carbenes as the carbon source, and water as the hydrogen source. A gold-catalyst has been used to transfer the carbenes to effect ... -
Index Coding, Error Correcting Index Codes And Matroids
In the problem of index coding, there is a central source sending messages to a set of receivers which demand messages over a noiseless broadcast channel. Each receiver knows a subset of messages which is referred to as ... -
Sparsity Driven Solutions to Linear and Quadratic Inverse Problems
The problem of signal reconstruction from inaccurate and possibly incomplete set of linear/non-linear measurements occurs in a variety of signal and image processing applications. In this thesis, we develop reconstruction ... -
Structural and functional studies on DNA synthesis and repair proteins
The work reported in this thesis includes structural and functional studies on thymidylate kinase and RecFOR pathway proteins from Thermus thermophilus HB8. In the first part, a study was performed on the thymidylate ... -
Interplay between the Mechanics of Flexible Substrates and Performance of Thin Film Transistors: Role of Buckled Geometry
Buckled Thin Film Transistor (TFT) resulting from the stress induced instability of thin films realized on a exible substrate can behave di erently than that of a planar device. The aim of this thesis is twofold: To ... -
Valorization of Residual Ligno-celluloses from Anaerobic Digesters Through Product Recovery
Complete digestion of lignocellulosic biomass during anaerobic digestion (AD) is impossible due to recalcitrance created by lignin, consequently leaving behind a significant part of the feedstock unconverted to methane. ...
