Abstract”

Because of the low maintenance and robustness induction motors have many applications in the industries. The speed control of induction motor is more important to achieve maximum torque and efficiency. Various speed control techniques like, Direct Torque Control, Sensorless Vector Control and Field Oriented Control are discussed in this paper. Soft computing technique “ Fuzzy logic is applied in this paper for the speed control of induction motor to achieve maximum torque with minimum loss. The fuzzy logic controller i ....etc

1. INTRODUCTION
Programmable logic controllers (PLCs) are members of the computer family capable of storing instructions to control functions such as sequencing, timing, and counting, which control a machine or a process. The PLC is composed of two basic sections, the Central Processing Unit (CPU) and the Input/Output (I/O) interface system. The PLC measures input signals coming from a machine and through the internal program provides output or control back to the machine.
Ladder logic is the programming language used t ....etc

ABSTRACT:


A PLC or programmable controller is a digital computer used for automation of electro mechanical processes, such as control of machinery on factory assembly lines.
In past humans was main method for controlling a system. More recently electricity has been used for control and early electrical based on relays. These relays allow power to be switched on and off without a mechanical switch it is common to use relays to make simple logic control decisions.

INTRODUCTION :-

PLC is a digitally operating electronic apparatus which uses a programmable (through dedicated language such as Relay Ladder Programming) memory for the internal storage of instructions for implementing specific functions such as logic, sequencing, timing, counting and arithmetic to control through digital or analog input output modules, various types of machines and processes.
The programmable controllers (PC) have developed as the heart of the automation of the industries. The PCs offer a number of advantages over th ....etc

Abstract”
This paper delivers some basic information about the security of web forms from web bots (robots). Possible threats are described and the article gives a list of some methods which can be used to protect web forms. The emphasis is on the CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) method that is most often used method. At the end of paper you can find one implementation of security methods using PHP and MySQL technologies.

Introduction

In the fast developing world, height of the buildings increased tremendously and the lift has become more of a necessary rather than luxury. When the number of floor increased the control mechanism required for the lift will become more complex. Programmable Logic Controllers are widely accepted industrial control device. With the growth in technology PLCs are now capable of advanced data manipulations, communications ....etc
