An Efficient Solution To Generalized Model Of A Transformer Winding And Localization Of Discrete Changes Based On Measurements
(2008-01-31)High voltage power transformers are designed to withstand a variety of overvoltages and short circuit forces. Occurrence of these events in a power system is natural, inevitable, and one of the main causes of transformer ... -
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 ... -
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 ... -
Electromagnetic Properties of Carbon Based Polymer Nanocomposites for Shielding, Chaffing and Camouflage Applications
High conductivity is a prerequisite for any material for it to be used in the field of electromagnetics. Metals like copper and aluminium are used for a variety of electromagnetic (EM) applications in industries like ... -
Empirical Studies of Load Generation for Data Center Networks
Data center networks form the backbone for modern Internet giants like Google, Facebook, Microsoft, and Amazon. Such networks consist of a layer of a large number of storage and compute servers connected through two or ... -
Emulation of wind turbine and sensorless control of doubly-fed induction generator for wind energy application

Enhancement of Small Signal Stability in Power Systems: Novel Approaches
The modern power system is a highly nonlinear system that operates in a constantly changing environment. Power system, need to maintain more or less flat voltage profile across the grid and maintain stability for small and ... -
Enhancing THC/NOX removal efficiency in diesel exhaust through catalyzing industrial wastes in the presence of electric discharge plasma
The consistent rise in air quality index in various cities has risen a worldwide concern toward the critical situation of air pollution and climate change. Despite the implementation of stringent regulations, the usage of ... -
Estimating probabilities of rare events in regenerative systems via importance sampling
In the high-speed networks currently being designed, the probability of packet loss required is very low, while the closed-form expressions for these events are usually not available. Therefore, one needs to estimate these ... -
Estimation of flashovers in the EHV/UHV lines on the east coast due to lightning produced by the Bay of Bengal cyclones
Electric Power is imperative for the modern world. The quality and reliability of the power supply can be impaired by several factors. Lightning is one such natural threat that disrupts the continuity of supply and can ... -
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 ... -
Experiential Sampling For Object Detection In Video
