VLSI architecture for the parallel computation of power system problems.
The large size and modeling complexities of power system problems have been providing the motivation for the use of fast computers and the search for new algorithms. The present trend of using digital computers for the ... -
Deposition and characterisation of spin-on-oxide (spoxide) using an organosilicon compound

Hybrid technique for adaptive delta modulators.
The simplicity and excellent noise immunity of Delta Modulation (DM) for digitally encoding speech waveforms has inspired many refinements to the basic invention. The most important refinement is in the form of Adaptive ... -
Description-Aided recognition of Handprinted characters
A description-aided character recognition scheme is presented for the recognition of handprinted characters. This scheme uses a hexagonal-cellular regular hexagon (CH) for curve following and feature extraction. Characters ... -

Nonlinear D/A and A/D converters some new techniques and applications
The development of new techniques for realizing nonlinear D/A and A/D converters, followed by their hardware implementation and/or computer simulation, has been described in this thesis. Also covered in the thesis are many ... -
Nonlinear propagation of surface acoustic waves
Some problems relating to the nonlinear propagation of surface acoustic waves on an isotropic homogeneous medium are studied in this thesis using a perturbation approach. The propagation of finite amplitude surface acoustic ... -

Performance analysis of multi image subspace algorithm for source localization in shallow water
In this thesis, the performance analysis of a subspace method for source localization (range and depth) in shallow water is discussed. The performance of a subspace method naturally depends on the quality of the subspace ... -
Some information theoretic and signal detection problems in the content of nearly Gaissian densities
It is well known that the use of the Gaussian assoimption when the governing prohahility density function is only -nearly Gaussian causes serious errors in estimation and detection theory. Defining a nearly Gaussian pdf ... -
Multistage pattern recognition schemes for automatic... ... verification
This thesis presents studies on the application of multistage pattern?recognition schemes in automatic speaker identification and verification systems for large populations. The success of speaker?recognition schemes in ... -
New clock synchronization techniques for digital telecommunication networks
Slip rate minimization in digital telecommunication networks is now an area of considerable importance. As the slip rate depends directly on the network clock stability, a number of clock synchronization techniques have ... -
SVD-based criteria for detection of the number of damped / undamped sinusoids in noise & their parameter estimation
The thesis addresses two problems: (i) detection of the number of damped/undamped sinusoids in noise, and (ii) their parameter estimation using a nonlinear least squares formulation. Following the information-theoretic ... -
Source location by signal subspace approach and ambient noise modelling in shallow water.
Source localization by signal subspace techniques in shallow water is difficult due to coherent multipath, resulting in non-planar wavefronts across the array. Also, the noise in shallow water is largely generated by wind ... -
Performance analysis of MVDR beamformer in finite data: with and without spacial smoothing.
In an MVDR beamformer, the array weights are chosen to pass the desired directional (look direction) signal without distortion while maximally rejecting interfering signals. The only assumption made is that the desired ... -
Passive localization of sound sources in shalow water simulation studies.
Array processing techniques for source localization in shallow waters can be classified as: i) Time delay estimation (TDE) techniques, and ii) High resolution (HR) methods. Time delay estimation techniques are two-step ... -
Design for Testability and fault analysis in PLAs and General combinational circuits
Programmable Logic Arrays (PLAs) are being extensively used in today’s LSI (Large Scale Integration) and VLSI (Very Large Scale Integration) circuit design as flexible building blocks for implementing combinational logic ... -
Log-periodic array of circular microstrip patches.
Presented in this thesis are the results of theoretical and experimental investigations carried out on the radiation characteristics of log-periodic array of electromagnetically coupled circular microstrip patch antennas. ... -
Performance evaluation of concurrency control algorithms for distributed database
Among the different issues associated with a distributed database system (DDBS), perhaps the most difficult one is Concurrency Control (CC). Although a large number of CC algorithms are available in the literature, very ...
