Abstract: This paper reviews different proposed techniques to overcome the water distribution system. The limitations of the reviewed options are also presented. The present water billing system uses analog water meters. Modern electronic device such as water flow sensor can be used to overcome basic limitations of analog meter such as less accuracy, human error while billing etc. This causes inconvenience to the society members as well as can be regarded as a waste of time. Water is precious available natural resource on the earth. However water is considered as the primary need of human beings. Population growth causes uneven distribution of drinking water in cities and need to monitor and control the consuming of water on minimum requirement base so proposed system improve the water supply monitoring and consuming of water for domestic. The available water billing system is tedious and time consuming process. Error in water billing can occur because of human interference.

Abstract: In this paper a comparative study on two methodologies namely Region Growing method and Zernike Moments were done. Normally the diagnosing of brain tumour is carried out by examining the Magnetic Resonance Imaging (MRI) scans. The detection of tumour from MRI Images was carried out independently by the two methodologies and the performance were compared based on two criterions: Root Mean Square Error (RMSE) and Time Complexity. The Results Analysis shows that brain tumour detection carried out by Zernike Moments method is having better performance than Region Growing method.

Keywords: Brain Tumour, Magnetic Resonance Imaging (MRI), Zernike Moments, Region Growing method.

Abstract: PID controller is used in most of the applications but it has some limitations like linearity, noise in derivative, etc., PI controller is used in some real life applications to overcome the limitations of PID controller. In this Paper, We implements PI controller for the control of speed of DC motor. It performs a comparative study with the PID controller of MRAC and Fuzzy logic controllers. PI Controller has two main parameters Kp and Ki. To find out the optimal values of Kp and Ki, Model Reference Adaptive Controller is used. It is observed that the PI controller with MRAC gives superior performance in speed control of DC motor as compared to MRAC PID controller and Fuzzy controller.

Keywords: DC Motor, PI Controller, MRAC, Fuzzy Logic Controller.

Abstract: For data transmission, an ideal communication relies on Low Power Design. Systolic array multiplier with the reversible logic is widely known among those techniques for synchronizing signals in DSP processor applications. Low power circuit design yields many favorable conditions like increased performance, system capacity, minimized cost etc. Reversible logic is a phenomenal approach to reduce heat dissipation and information loss. Among basic arithmetic operations, Multiplication demands more processing time and seek complex hardware. As Conventional Systolic Array Multiplier is designed using irreversible logic gates, there is undesired power dissipation. So, to improvise this downside, this paper illuminates the design of low power Systolic Array Multiplier using reversible logic gates which performs data processing in Parallelism manner [5]. Power, delay, garbage outputs and quantum cost is calculated mathematically in this paper. Finally, Cadence Virtuoso is used to obtain simulation results. 25mW is the power for the proposed design when the power of individual components is added theoretically. The overall power of the circuit is 14 W.

Abstract: As welding machines are now being used in many applications even in household purposes without any trained person, the system has to be compact and should have a high safety measures. In order to make the system compact, we make use of power electronic components in the machine which decreases the size of the machine to the large extent. But with use of power electronic component there are others problems like harmonics and because of these the Power factor of the machine will decrease. In order to improve the power factor, various power factor correction techniques can be adapted. In this paper, a systematic review of boost rectifier with power factor correction using PWM IC’s is presented.

Abstract: Custom Power (CP) devices that mitigate these power quality problems have gained more attention in the recent decades. This work deals with conceptual study of DSTATCOM during voltage sag and swell on the power network. Power quality has become an important factor in power systems, for consumer and household appliances with production of various electric and electronic equipment and computer systems. The main causes of a poor power quality are harmonic currents, poor power factor, supply voltage variations etc. A complete simulation model of the proposed system will be developed in Matlab / Simulink Environment. The system will be simulated with different control strategies under different operating conditions for comparison.

Abstract: This paper deals with the controlling of the non-linear system using fractional order IMC-PID controller. The IMC-PID controller does good set-point tracking but poor disturbance response essentially for the process which has a minute time-delay/time-constant ratio. The study of different methods of IMC design and I M C based PID controller has been intended for a plant transfer function to include the advantages of PID controller in IMC. The intended of fractional order PIλDμ controller in which the orders of the Integral (I) and Derivative (D) parts λ and μ are fractional. The purpose of introduction of these two parameters is to ensure the robust performance of the system. The IMC is used to handle non-integer system with time delay. IMC PID controller has been designed for a plant transfer function to incorporate the advantages of PID controller in IMC. In order to reduce the number of tuning parameters and effects of time delay, the fractional order internal model control scheme is used.
