Introduction of Dielectrics

Dielectric is an entity ,in which equal positive and negative charges separated by equal small distance.
In which each molecule has permanent dipole moment P
This type of materials are known as polar materials
Different molecules has different different directions of the dipole moment.
In Non polar materials ,The centre of the positive charge distributution in an atom or molecules coinci ....etc

Introduction.
Definition.
Control theory is a combined branch of mathematics and Engineering that deals with the dynamical systems. The desired output of the system is called reference and when one or more outputs desire to follow the reference over time a controller is designed and. It helps in manipulating the input to provide the desired output.
The role of control theory can be understood with the help of a simple example. Let ....etc

Fuzzy Control Model Optimization for Behavior-Constant Traffic Routing Under Information Provision

Abstract:
This paper presents an H-infinity filtering approach to optimize a fuzzy control model used to determine behavior consistent (BC) information-based control strategies to improve the performance of congested dynamic traffic networks. By adjusting the associated membership function parameters to better respond to nonlinearities and modeling errors, the approach is able to enhance the computation ....etc

This type of gear box is similar to the constant mesh type in that all the gears on the main shaft are in constant mesh with the corresponding gears on the lay shaft. The gears on the lay shaft are fixed to it while those on the main shaft are free to rotate on the same. Its working is also similar to the constant mesh type, but in the former there is one definite improvement over the latter. This is the provision of synchromesh device which avoids the necessity of double declutching. The parts which ultimately are to be engaged are first broug ....etc

Biasing a diode means applying appropriate DC voltage to a diode. A forward biased diode conducts
easily whereas reverse biased diode practically conducts no current. It means that forward resistance of a
diode is quite small as compared with its reverse resistance.
Forward current is the current flowing through a forward biased diode. Every diode has a maximum
value of forward current, which it can safely carry. If this value is exceeded, the diode may be destroyed
due to excessive heat. Reverse current or leakage current is the current t ....etc

Instantaneous power, p(t) = v(t)i(t)

Power, p(t) value
positive power transmit/dissipate by load
negative power return from the load
Since p(t) is power transmits by load, then it is the average power, P at load
P is also known as active power, real power or true power measured in unit of Watts.

REACTIVE POWER
Instantaneous power
p(t) = v(t)i(t) = VI sin 2 t
Average power is zero
The product of VI is called ....etc
