De Novo design of protein secondary and super-secondary structural elements : Insights from the crystal structures of a,B-dehydrophenylalanine containing oligopeptides- a novel weak-interaction based design strategy
The surface complementarity (charge, structural, etc.) plays a vital role in molecular recognition and association. It appears that the modes of interaction between aliphatic–aliphatic, aliphatic–aromatic, and aromatic–aromatic ... -
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 ... -
Deep learning methods for light fluence compensation in two-dimensional and three-dimensional photoacoustic imaging
Photoacoustic imaging (PAI) employed the special properties of light or photons to obtain detailed images of organs, tissues, cells, and even molecules. The method allowed for a non-invasive or minimally invasive examination ... -
Dendrimer Interactions with Cell Membrane and Pore Forming Toxins
Dendrimers are hyper-branched polymeric nanoparticles with a central core molecule connected by successive dendritic branching layers. The structure controlled parameters of den-drimers such as size, shape, surface chemistry, ... -
Denoising And Inpainting Of Images : A Transform Domain Based Approach
(2009-05-25)Many scientific data sets are contaminated by noise, either because of data acquisition process, or because of naturally occurring phenomena. A first step in analyzing such data sets is denoising, i.e., removing additive ... -
Density functional and computer simulation studies of colloidal suspensions
Colloidal suspensions of polyballs (polystyrene spheres) are good model systems for the study of both structural and dynamical properties of solids and liquids because the pair-wise interaction between the colloidal particles ... -
Design and analysis of a miniaturized Atomic Force Microscope scan head
An Atomic Force Microscope (AFM) is a type of scanning probe microscope used for nano-scale characterization, topography imaging and manipulation of conducting and insulating samples, at sub-nanometer resolution. Its ... -
Design and Analysis of Surface Acoustic Wave Filters
The generation and detection of surface acoustic waves (SAWs) using interdigital transducers (IDTs) on a piezoelectric surface have been used to produce many high performance Band Pass Filters. This thesis focuses on ... -
Design and construction of a pulsed high magnetic field facility and high field magnetoresistance studies in some semiconductors
Negative magnetoresistance at 77?K saturates to a value of 0.04 to 0.06 and shows anisotropic behavior. In this connection, a critical review of the experimental results and the theoretical models of negative magnetoresistance ... -
Design And Development Of A Liquid Scintillator Based System For Failed Fuel Detection And Locating System In Nuclear Reactors
(2009-07-02)Failed fuel refers to the breach in the fuel-clad of an irradiated fuel assembly in a nuclear reactor. Neutron detection or gamma detection is commonly used in Failed Fuel Detection and Locating (FFDL) system to monitor ... -
Design and Development of Cryogenic Transfer Lines and Studies on Flow Phenomena
Cryogenics refers to the field of science and engineering below 123 K (-150 ºC). Also it deals with the production, utilization and maintenance of the same. Below 123 K, the so called “Permanent gases” such as Argon, ... -
Design and Development of Fiber Bragg Grating Sensor Devices for Aerospace Applications
Optical sensors are becoming increasingly popular and gradually replacing electrical sensors due to their faster response, higher sensitivity, immunity to electromagnetic interference and electrical sparking. The advancements ... -
Design and Development of Fiber Bragg Grating Tactile Sensing Devices for Novel Applications in Engineering and Biomedical Fields
Among the five human basic senses, touch is thought to be the sense that makes the world 'real' to us. Tactile sensors are a category of artificial sensors that acquire information through physical touch. Tactile sensors ... -
Design And Development of Linear Moving Magnet Synchronous Motor Based Twin PTC And HTS Level Sensor for LOX Recondenser
(2017-09-23)Cryocoolers are closed cycle devices which produce cooling below 120 K. Usually, one or two linear motors are used to drive one pulse tube cryocooler. Cryocoolers are used for various applications like, cooling of infra ... -
