Please let me know the disadvantages of Tor network.
I have few points with me like..
1)Tor network is very slow
2)It require more bandwidth
3)Attacks like Denial of service and Man in middle are possible.
Need more disadvantages..

Thanks in advance :) ....etc

SPEED CONTROL OF SYNCHRONOUS MOTOR BY USING VARIABLE FREQUENCY DRIVES



ABSTRACT :

A novel open-loop speed control method for induction motors that provides high output torque and nearly zero steady-state speed error at any frequency is presented. The control scheme is based on the popular constant volts per hertz (V/f) method using low-cost open-loop current sensors. Only stator current measurements are needed to compensate for both stator resistance d ....etc

Variable Frequency Drives

Introduction
¢ Variable Frequency Drives are devices which control the speed of alternating current(AC) electric motors by controlling the frequency of the supply voltage of the motor. ¢ Motor-driven systems are designed to handle peak loads. If the system is running at a reduced load for some period of time, it will lead to energy inefficiency. ¢ With Variable frequency drives and the ability to adjust the speed of the motor, enables you to match the motor output to load requirement ....etc

Abstract

      Various low-latency anonymous communication systems such as Tor and Anonymizer have been designed to provide anonymity service for users. In order to hide the communication of users, most of the anonymity systems pack the application data into equal-sized cells (e.g., 512 B for Tor, a known real-world, circuit- based, low-latency anonymous communication network). Via extensive experiments on Tor, we found that the size of IP packets in the Tor network can be very dynamic because a cell is an application concept and the IP l ....etc

Discrete Variable Frequency Soft Starting on DSP-based Voltage Controller-Fed IM Drive
Abstract
GThyristorized soft starters are being used as inductionmotor starters in fan or pump drives, ere, the principleofwhich is based on the control of variable voltage and constantfrequency. One ofthe demerits of the soft starters is that a smallreduction in voltage produces a considerable drop in electromagnetictorque, which may cause the motor with loads failureto start. A new control strategy is proposed to improve electromagnetictorque at s ....etc

Abstract:-
Our varying industrial needs demand more precise control of the outputs of our basic electrical prime movers i.e, THE MOTORS. Basically dc motors are easy to control compared to their ac counter parts, but they have their own limitations with increase in capacity. Conversely ac motors in particular squirrel cag ....etc
