Wind blowing over sand on Earth produces decimeter-wavelength ripples and hundred-meter– to kilometer-wavelength dunes: bedforms of two distinct size modes. Observations from the Mars Science Laboratory Curiosity rover and the Mars Reconnaissance Orbiter reveal that Mars hosts a third stable wind-driven bedform, with meter-scale wavelengths. These bedforms are spatially uniform in size and typi...
The smart power grid promises to improve efficiency and reliability of power delivery. This report introduces the logical components, associated technologies, security protocols, and network designs of the system. Undermining the potential benefits are security threats, and those threats related to cyber security are described in this report. Concentrating on the design of the smart meter and i...
Abstract This paper proposed the microcontroller based vector impedance meter, which can be used to measure unidentified impedance of the system. The microcontroller read only four samples from two voltage signals, the first voltage is proportional to the voltage across the impedance while the second voltage is proportional to the current passing through it. A novel algorithm is then used to ge...
