Segmentation and classification of color images of blood cells
Segmentation and Classification of White Blood Cells for Automated Differential Count Abstract and Synopsis Introduction Medical image analysis plays a major role in providing quality healthcare. Improved imaging techniques ... -
Analysis of vectorcardiograms using fourier descriptors
This thesis presents the results of analysis of three important aspects of vectorcardiograms: rhythm monitoring, morphological studies, and data compression. For this purpose, the method of Fourier Descriptors (FDs)-a ... -
Digital methods for ECG analysis
The objective of the present thesis is to develop digital processing techniques for ECG signal analysis to be implemented on a dedicated system in a clinical environment. A computationally efficient algorithm for event ... -
Voltage distribution studies on ZnO surge arresters
The lightning activity and switching operations cause overvoltages in power systems. These overvoltages are detrimental to the insulation of power system equipment. It is therefore essential to limit these overvoltages. ... -
A Critique Of k-factor Method With Special Emphasis On Its Implementation
Estimation of impulse waveform parameters (viz. test voltage, front time, tail time) from digital data acquired during high voltage impulse tests-particularly on transformers, cables, and reactors-poses difficulties due ... -
Repositioning of garter springs of neclear fuel assembly by electromagnetic technique
The development of an electromagnetic technique for remote repositioning of metallic spacers called Garter Springs (G/S) has assumed great importance for nuclear reactors. The G/S act as spacers between the coolant tube ... -
Structure of transfer function of transformers with special reference to interleaved windings
The post digital era in high voltage impulse testing of transformers witnessed renewed activity in an otherwise dormant field due to the introduction of the transfer function (TF) approach. The TF method provides a more ... -
Design and implementation of higher order kalman filter for tracking highly maneuvering targets in an airborne TWS radar / by Shishir Kumar Singh
An airborne Track?While?Scan (TWS) radar has an antenna mounted on top of the aircraft. The motion of the antenna limits the data rate of airborne TWS radars to very low values. Further, because of its large search volume, ... -
Fault-tolerant data driven distributed architecture for future generation avionics
The mission requirements of fighter aircraft have become increasingly complex over the years. In addition to the traditional roles of air combat and air?to?ground bombing, the modern combat environment requires penetrating ... -
Studies on a thermal performance of totally enclosed fan cooled induction motors
Out the three essential aspects of electric motor design-namely electromagnetic, mechanical, and thermal-the technology for thermal design happens to be the least developed, despite the fact that thermal performance ... -
On gaussian devolution.
This thesis is concerned with the problem of deconvolution of discrete signals convolved with a discrete Gaussian. It examines the problem for both one? and two?dimensional signals. The problem of deconvolution arises in ... -
Development of Artificial neural networks approach for estimation of EHV/UHV transmission line enrgization peak overvoltages
In India, the available generation and installed capacity has been increased many folds in the last two decades. Next?higher 765 kV transmission lines are planned to reinforce the existing 400 kV networks. The systems are ... -
Compressed domain analysis of video sequences
Digital video compression has become an essential part of day?to?day life due to a wide variety of applications, including video delivery over the Internet, television broadcasting, video streaming, video conferencing, as ... -
Wavelet domain residual redundancy based descriptions
With the growing applications for transmission of image and video over computer networks and wireless channels, reliable communication methods are desired. In packet?based transmission systems, packet losses occur in ... -
Delayless adaptive IFIR structures and algorithms
Adaptive Filtering (AF) [1], [2] is used in a variety of applications such as system identification, channel equalization, active noise cancellation, and echo cancellation. Over the years, significant research efforts have ... -
Algorithms for operation planning in deregulated power systems
The electric utility industry has been going through a revolutionary change over the past decade. The change in perception of economy and social good by governments has been forcing the electrical industry worldwide to ... -
Coupling Of Electromagnetic Fields From Intentional High Power Electromagnetic Sources With A Buried Cable And An Airborne Vehicle In Flight
Society’s dependence on electronic and electrical systems has increased rapidly over the past few decades, and people are relying more and more on these gadgets in their daily life because of the efficiency in operation ... -
