A Study of Some Conformal Metrics and Invariants on Planar Domains
The main aim of this thesis is to explain the behaviour of some conformal metrics and invariants near a smooth boundary point of a domain in the complex plane. We will be interested in the invariants associated to the ... -
Decomposition of the tensor product of Hilbert modules via the jet construction and weakly homogeneous operators
Let ½ Cm be a bounded domain and K :£!C be a sesqui-analytic function. We show that if ®,¯ È 0 be such that the functions K® and K¯, defined on £, are non-negative definite kernels, then theMm(C) valued function ... -

Analysis of Laterally Loaded Piles in Clayey Soils with Sloping Ground
In the present study, a small scale 1-g model test has been developed in the laboratory to study the behaviour of a long flexible single pile embedded in a slope of soft clay with different slope angles and L/D ratios, and ... -
Theoretical studies of chemical dynamics in complex systems: Nanoconfined water, microdroplets, biomolecular hydration layer, and water-mediated protein association
The thesis contains theoretical studies of the structure and dynamics in different complex systems. Depending on the systems and properties of interest we divide the thesis into five parts. In the first part, we study ... -
A Fast Constant-Time Approximation for Locally Adaptive Bilateral Filtering
Smoothing is a fundamental task in low-level image processing that is used to suppress irrelevant details while preserving salient image structures. The simplest smoothing mechanism is to average neighboring pixels using ... -
Understanding the Significance of Ydcp, a Putative Peptidase Encoding Gene, in Virulence of Salmonella
Salmonella is a recognised enteric pathogen which infects several mammalian and avian hosts through faeco-oral route and establishes either a localised gastrointestinal inflammation and diarrhoea or a systemic fever, ... -
