It is more than 99.9% pure water and is characterized by its volume or rate of flow its physical condition, its chemical constituents, and the bacteriological organisms that it contains. Increasing volumes of domestic, hospital and industrial wastewater are being produced in cities around the world. Cities in developing countries lack resources to treat wastewater before disposal. Even where expensive wastewater treatment plants are installed, only a small percentage of the total wastewater volume is treated before discharge resulting in rivers, lakes and aquifers becoming severely contaminated. So there is great need to treat waste water. We can treat such water by various methods. The contaminants in wastewater are removed by physical, chemical, and biological means. The individu...

To overcome this problem, "Automatic Multistoried Car Parking System" is best solution. The system is based on PLC. It consists of one main display at the ground floor which is basically counter that displays number of cars in each floor. In each slot consist IR sensor which indicate that parking space is available or not on that particular slots. There is facility of lift to carry the car to up and down. Movement of lift controlled by motor. At the ground level LED is providing to indicate position of lift. When car is entered at parking system, controller check whether space is available or not. If all spaces are vacant, the lift will park the vehicle on priority basis. After parking the car lift go to original position and controller send the signal to the display that car is parked properly with slot number. For the impark the car operato...

Firstly, the ECG signal is filtered by a band pass filter, and then it is differentiated. After that, the Hilbert transform and the adaptive threshold technique are applied for QRS detection. Finally, the Principal Component Analysis is implemented to extract features from the ECG signal. Nineteen different records from the MIT-BIH arrhythmia database have been used to test the proposed method. A 96.28% of sensitivity and a 99.71% of positive predictivity are reported in this testing for QRS complexity detection, being a positive result in comparison with
