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 ... -
Measurements of the ionsation current Growth and the ratio of Diffusion coefficient to mobility for electronics in feebly Attaching gases
For a proper understanding of the mechanism of breakdown in gases, it is essential to have knowledge of the swarm coefficients, namely, the sparking potentials (V?), Townsend's primary (?/N) and secondary (?) ionization ... -
On calculation of corona and breakdown voltages of gaseous insulation with special reference to elecrro-negetive gases and their mixtures
In the design of any insulation system, mechanical, electrical, thermal, and economic considerations are generally of prime importance, and many factors contribute to the type of insulation used in a particular system. In ... -
Gaseous breakdown below paschen minimum in ExB fields
Some investigations about the electric discharge in a coaxial geometry electrode are explained in the transition range, namely, Townsend–Penning discharge for the dry air. The existing theory of 0.05 to 0.3 Torr is extended ... -
Rise and delay time of a vaccum gap triggerd by an exploding wire
Detailed investigations on the rise time (t?) and delay time of a vacuum gap employing an entirely new type of trigger mode using an exploding wire have been reported in this thesis for the first time. A large quantity of ... -
Speech Based Low-Complexity Classification of Patients with Amyotrophic Lateral Sclerosis from Healthy Controls: Exploring the Role of Hypernasality
Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disorder characterized by motor neuron degeneration, leading to muscle weakness, atrophy, and speech impairments. Dysarthria, an early symptom in approximately 30% ... -
Modeling, Characterization, and Control of Switched Reluctance Motors
Switched reluctance machine (SRM) is known for many advantages such as permanent magnet-free operation, robust structure, low rotor inertia, low manufacturing cost, and excellent fault-tolerant capability. Hence, SRM has ... -
Characterization and Enhancement of Dysarthric Speech for Amyotrophic Lateral Sclerosis: A Source-Filter Perspective
Dysarthria is a motor speech disorder that affects different aspects of speech functions, like respiration, phonation, articulation, prosody, and resonance. It progressively compromises the intelligibility and naturalness ... -
Intelligent techniques for fault location in distribution systems using artificial neural networks
Power Distribution System forms a vital part of any Electric Power System. It acts as a final power delivery stage to the consumers. Hence, its study is important for the development of an efficient and reliable Power ... -
Neural networks for invariant recognition of 2-D objects
This thesis studies the problem of translation-, rotation- and size-invariant recognition of two-dimensional objects. This problem can be framed as follows: Given (i) a set of object descriptions in terms of either global ... -
Hypercube variant interconnection networks
The attractive properties of the hypercube have made it a popular interconnection network topology for the design of multicomputers. Researchers have been modifying the hypercube topology in subtle ways to improve upon a ... -
Study of parallel distributed schemes for combinatorial optimization.
This thesis is concerned with Parallel Distributed Optimization techniques for solving Combinatorial Optimization (CO) problems. Given a finite set of configurations and a cost function over them, a CO problem requires ...
