Abstract: Automation has come up with solutions towards; Higher productivity,Superior quality of end product,Efficient usage of energy and raw materials and Improved safety in working conditions etc. Programmable Logic Controllers are important element, who are playing major role in it in automation of process Industries. For anolog signals it has provided economic solutions. Here we have given short description on utility of function blocks FC 105 and 106 in controling temperature in various zones of Extruder. This function of PLC is useful for other analog signals also i.e. Pressure, Flow, conductivity ,density, sound etc.. Some of the objective which are of directly use of an Industrial Automation Electronic Engineer to serve Industries in order to boost up productivity are as follows;

Abstract: The scheme that gives the information about the different modulation techniques to specify the benefits of filter bank multi-carrier, single- carrier frequency division multiple access and offset quadrature amplitude modulation. The technique which is better then conventional FBMC system, comprises of precoding technique is a combination of Pruned Discrete Fourier Transform with one-tap scaling is developed. Cyclic Prefix is not required for this technique and Out-of –Band emission is lower. This technique restores complex orthogonality, the time-period from one block to another is latency, it allows low latency transmissions and provides low Peak to Average Power Ratio. The reliability increases in doubly-selective channels; its applications comprises of uplink transmission in wireless communication. Background: The Pruning is the method used to filter the unwanted signals, and leads to the collection of desired signals. The modified.....

Abstract: Home security using embedded systems which involves the detection of a movement or a motion which has always been very important in many of the researches. In the research work the process of interfacing a PIR sensor with a micro controller along with the Arduinocan be learned. The research work will interface an arduino with PIR module, blink a LED and beep a buzzer whenever a movement is detected. The following components will be needed mainlysuch as PIR sensor, buzzer, LED will be needed to build the research work. The embedded system is used for safety, performance; software is used for flexibility and capabilities.
