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 ... -
Learning Algorithms for stochastic automata-
Reported in this thesis is the study of nonlinear learning algorithms or reinforcement schemes for multi-state stochastic automata acting in stationary random media with unknown response characteristics. Such stochastic ... -
Optimal resource allocation in packet networks
This limitation can be overcome by considering a Non-Rate Proportional resource allocation. We present an Optimal Call Admission Control (CAC) algorithm for Generalized Processor Sharing (GPS) schedulers that performs a ... -
Diffusion approximation models for broadband integrated networks and their performance evaluation
In this thesis, we first consider the VBR video traffic modelling, then the reactive congestion control of VBR and BET traffic, and finally the optimal scheduling scheme for CBR traffic over the broadband integrated services ... -
Array combiner For GMRT
Today, Radio Astronomy has developed into a highly complex, interdisciplinary subject. Many radio astronomical problems need technologies from different engineering fields and knowledge from many scientific fields, at times ... -
Performance analysis of TCP connections with RED control and exogenous traffic
The Transmission Control Protocol (TCP) is the main protocol used in the Internet for data transfer applications. Certain congestion control mechanisms have been incorporated in host implementations of this protocol which ... -
Study of simulated xy plasma at k-band
Spacing between the wires (in mm) Spacing between the grid structures (in mm) Free-space wavelength (in mm) Simulated plasma frequency (in Hz) Frequency of the oscillator (in Hz) Refractive index Equivalent plasma density ... -
DPLL's for network synchronization: a new approach.
A new DPLL has been described in this thesis to overcome some of the limitations of the conventional second-order DPLL in the context of network synchronization applications. The analytical and computer simulation studies ... -
Design and development of subject storage and learner models for WESLA
With the advent of the web, the Internet has evolved into a user-friendly medium, capable of high-speed on-demand information delivery. Web-based distance learning systems support distributed and asynchronous learning. ... -
Application of coherent optical techniques in the study of serve mathematical operations
The aim of the project is to study some of the mathematical operations by coherent optical processing techniques with the help of gratings. These mathematical operations are namely: (1) Translation (2) Addition (3) ... -
Coherent optical image deblurring with computer generated fourier plane filters
This thesis deals with the fabrication techniques of optical filters for use in a coherent optical processor for correcting images that are degraded by space-invariant blurs. In particular, techniques wherein one can utilize ... -
Kinematical conservation laws and applications
Study of wave motion is important in the field of fluid mechanics. The equations governing the motion of an inviscid compressible fluid form a hyperbolic system of quasi-linear equations and hence give rise to nonlinear ... -
Grushin Multipliers and Toeplitz Operators
This work investigates advanced concepts in functional analysis and partial differential equations, focusing on Sobolev spaces and their weighted variants. The study explores properties of functions in Lp(Rn+1)L^p(\mathb ... -
A Study and development of numerical techniques for the solution of integral equations
We have shown that given any function f(x), there exists a unique f?(x), as defined by the relation (2.1), which exactly coincides with f(x) at the points jh. By using the package MATHEMATICA, we can choose a k, such that ... -
Benard-Marangoni convection and instability in a layered fluid system
Buoyancy-driven instability has been well established since the pioneering work of Rayleigh, who showed that convection, called Bénard convection, occurs only when the Rayleigh number, which is a ratio of buoyancy force ... -
Some aspects of synthesis, structure and stability of quasicrystals.
The celebrated discovery of quasicrystals has broadened our outlook towards the various possibilities of atomic arrangements in the solid state. Many fascinating problems in the field of quasicrystals have emerged, which ...
