There are many ways of batterycharging but constant-currentcharging, in particular, is apopular method for lead-acid and Ni-Cd batteries. In this circuit, the batteryis charged with a constant current thatis generally one-tenth of the batterycapacity in ampere-hours. So for a4.5Ah battery, constant charging currentwould be 450 mA.This battery charger has the followingfeatures:1. It can charge 6V, 9V and 12V batteries.Batteries rated at other voltagescan be charged by changing the valuesof zener diodes ZD1 and ZD2.2. Constant current can be set ....etc

Abstract
This paper presents a new technique for online identificationof an induction motor rotor time constant. The techniqueis designed for a shaft-sensorless indirect field-oriented controlinduction motor drive with a model reference adaptive system(MRAS)-based speed estimator. The MRAS estimator is sensitiveto the changes in the rotor time constant, and online identificationof that parameter is essential. If rotor parameter error exists, itdoes not only change the achieved rotor speed, but it also changesthe dynamic behavior of the ....etc

Abstract—
The admission control problem is concerned with
determining whether a new task may be accepted by a system
consisting of a set of running tasks, such that the already admitted
and the new task are all schedulable. Clearly, admission control
decisions are to be taken on-line, and hence, this constitutes a
general problem that arises in many real-time and embedded
systems. As a result, there has always been a strong interest
in developing efficient admission control algorithms for various
setups. In this paper, we pro ....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 ....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 ....etc
