The underlying theme of the experimental investigations carried out in the present thesis has been to find newer physical and chemical methods of generating polymer films with macroscopic, mesoscopic and nanoscopic patterns. ...
Image segmentation is concerned with decomposing a given image into its constituent regions or objects. It is an important preliminary step in diverse fields of application like object recognition, image compression, medical ...
The philosophical exploration of consciousness has a long history in both Indian and Western thought. Some of the conceptual models and analyses that have emerged in one cultural framework may be profitably reviewed in the ...
Pagladia multipurpose reservoir, located on the river Pagladia, a major north bank tributary of Brahmaputra, proposes to serve three purposes, namely, flood control, irrigation and power generation. In order to achieve ...
The geographical location of northeastern region of India is distinctive in terms of land border with neighbouring countries. The region shares about 33 percent of the country's total international border. Out of the seven ...
Materials based on manganese oxides are generally known as manganites. The manganites RMnO3 (R= Trivalent rare earth elements) and AMnO3 (A= Divalent alkaline earth elements) are known to be insulating with antiferromagnetic ...
This dissertation describes the successful efforts on the development of new synthetic methodologies in protection-deprotection chemistry for thio- and dethioacetalization of carbonyl compounds and desilylation of ...
This thesis consists of experimental investigations in the following two areas. (i)Stabilization of single soap bubbles and their spectroscopic investigation. Observation o Marangoni effect driven upwardly mobile fluid ...
The present thesis is based on the results of investigation of a few chosen aspects of metal acetylacetonates, oxofluorochromates (VI), ammonium tribromides and peroxovanadates (V). It constitutes, in part, an interpretative ...
Present work mainly focus on two lithographic techniques viz. selective laser ablation lithography and atom lithography using dipole force. The work on atom lithography using dipole is on simulation of atomic trajectories ...
The chemistry of bis- phenols and its derivatives is one of the important aspects of synthetic organic chemistry. This subject has gained relevance because of the various applications of bis-phenols which may involve some ...
Depending upon the distance of the confining boundaries from the discharge, a jet can be analysed as a free jet or a bounded one. If the boundaries (parallel to inlet axis) are sufficiently away from the origin of the jet, ...
British novelist John Fowles (1926-), is considered a novelist of ideas, and ""a protean novelist, always breaking moulds, trying something new"" (WH 448). Willing to risk himself in each of his fiction in originality, he ...
The present work is aimed towards generation and characterization of the arrays using various interferometric configurations. Heterodyne interferometric configurations using polarized lights was developed and studied. The ...
In this thesis, we have presentrd a comprehensive study of modeling point defects in high and low symmetry crystals with Polarizable Point Ion (PPI) model. We worked out an alternate scheme to estimating energies of point ...
Stability analysis of high speed machinery based on rigid rotor model mounted on rigid supports was found to be inadequate for stability predictions. Critical speeds of a rotor are frequently computed assuming the bearing ...
The median filter is a nonlinear filter that outputs the median of the data inside a moving window of predetermined length and has been traditionally used to remove impulse noise from images. The filter is known for its ...
The discovery of high transition temperature (Tc) superconductivity in (La-Ba)-Cu-O system with Tc = 30 K in1986 by Bednorz and Muller triggered the development of several high Tc Cu- O based superconductors. Among them, ...
