Water resource availability is an important problem as water is basically used for everything we make. In a water distribution process the level and flow must be always controlled. Therefore, the parameters of the system must be known at any moment. This paper presents an automatic level control system which is analyzed in terms of reliability in order to present solutions to clarify how such systems...
For the sake of higher cell density while achieving near-zero standby power, recent research progress in Magnetic Tunneling Junction (MTJ) devices has leveraged Multi-Level Cell (MLC) configurations of Spin-Transfer Torque Random Access Memory (STT-RAM). However, in order to mitigate the write disturbance in an MLC strategy, data stored in the soft bit must be restored back immediately after the hard...
In order to realize the function of accurate measurement, multipoint collection and wireless transmission on various environmental monitoring factors in the workshop, a workshop environment monitoring system is proposed based on the technology of internet of things. A number of wireless monitoring nodes are set up in each workshop to collect a variety of environmental information, then transmit the...
This paper deals with a new method PMSM driver inverter faults detection and isolation based on EKF (Extended Kalman Filter). Firstly, a nonlinear model of PMSM diver where the on resistance of inverter FET is included as state variable is derived. Secondly, the method to detect and isolate inverter fault from the estimated on resistance is presented. Finally, the usefulness of the proposed scheme...
This paper highlights the U.S. Department of Energy's Smart Grid R&D projects on dynamic optimization of distribution grid operations through integration of advanced sensing, communication, and control technologies. The progress and planned activities of the following programs are discussed: Renewable and Distributed Systems Integration demonstrations, microgrid developments, the Smart Grid Regional...
