Hyperspectral Image Fusion with Implicit Regularization
Hyperspectral (HS) satellite images contain rich spectral information but generally suffer from low spatial resolution. In contrast, multispectral (MS) images offer higher spatial resolution but only a limited number of ... -
Electrical breakdown and post breakdown studies in sodium vapour using coxial; cylilndrical electrode configuration
The advancing technology of power circuit breakers has led the way for the study of arcs in gas?filled as well as vacuum circuit breakers. The spectroscopic investigations of such arcs have clearly shown the presence of ... -
Coaxial triggered vacum gap : switching and delay characteristics
Vacuum is an excellent insulator, albeit has a poorly defined intrinsic electric breakdown strength. Because of this, the ordinary vacuum gap with only two electrodes is unsuitable for switching applications. The electric ... -
Fast adaptive multipole-algorithm for scattering from inhomogeneous dielectric cylinders of arbitrary cross-section
The work reported in this thesis is concerned with the rapid solution of electromagnetic scattering problems involving inhomogeneous dielectric cylinders of arbitrary cross?section. In particular, attention is focused on ... -
Pressure gradient flow electrical conduction in polar liquids
Polar liquids like nitro-, chloro- and bromobenzenes find possible applications in electrostatic generators, impulse voltmeters etc. In this work natural conduction in these liquids has been studied at electric fields of ... -
Electrical discharges in mercury vapour in a magnetic field
Langmuir probe method is applied to determine the n? and T? of a low-density, collisional plasma in mercury vapour under moderate magnetic field strengths. The charge density evaluated by Bohm's method and the orbital ... -
Learing automata algorithms for connectionist systems local and global convergence
Connectionist systems have been studied with much interest as models for the brain and also as systems which work in a parallel and distributed manner. These systems exhibit desirable properties such as learning capability ... -
Excitation dynamics in GaAs quantum wells
The dynamics of excitons is studied using time?resolved photoluminescence. We deduce experimentally, for the first time, the intrinsic homogeneous linewidth of free excitons in GaAs quantum wells. The scattering rate of ... -
Nonexponential decay of sound in rooms
(i) The above analysis of decay of sound in rectangular rooms under various boundary conditions shows that the overall decay is in general non?exponential because the normal modes corresponding to different angles of ... -
Studies on the role of spatial coherena in the lau phenomenon
The Laue effect is of fundamental importance in the domain of optical interference phenomena. In the Laue experiment, interference fringes are formed in the far field when an extended source illuminates two gratings placed ... -
Relative efficiencies of devanagari and tamil scripts for reading
This thesis is devoted primarily to some of the problems involved in reading with particular emphasis on Devanagari and Tamil scripts. Scripts are considered as codes and their performance examined on the basis of information ... -
Knowledge-based mining of multi-database for associations
Knowledge Discovery in Databases (KDD) uses knowledge engineering tools and database technology to extract hidden patterns from databases. Data mining is a step in the KDD process that finds useful patterns in the data. ... -
Stokes polarimetry and the measurement of vector magnetic fields in solar active regions.
The aim of this thesis has been measurement of Stokes profiles and vector magnetic fields in sunspots using the Kodaikanal Tower/Tunnel Telescope and spectrograph. Although this coelostat telescope had been constructed ... -
Design and perfomance evaluation of bus access schemes for salan-an experimental local area network
Local Area Networks (LANs) spanning a limited geographic area have emerged of late as a field of wide applicability. One of the prime factors governing the design of a LAN is the Medium Access Control (MAC) scheme which ... -
Combinatorial algorithms for determinant based problems
The thesis started with the early history and development of the theory of determinants. All the important results up to the 1880s were presented through a computing perspective. Pfaffians are closely related to determinants; ... -
Application of finite graph models of context fue languages.
A finite graph model for a context?free language is proposed. The model is called an extended transition system; its nodes encode [pushdown automata state, top stack symbol] pairs and its arcs encode pushdown automaton ... -
Simulative performance analysis of ATM switching fabrics
Asynchronous Transfer Mode (ATM) has emerged as the major technology paradigm for the implementation of the Broadband Integrated Digital Services Network (B?ISDN). In ATM, all forms of information such as voice, video and ...
