This paper presents the installation and field measurements of a prototype microhydro power (MHP) generation system based on an underwater turbine generator. The studied MHP system employs the energy of flowing water in the agricultural irrigation of one of the irrigation ditches of the Yunlin Farmland Irrigation Association, Taiwan. The irrigation ditches are basically used for distributing irrigation...
Network lifetime and coverage are viewed as the dominating considerations in designing the structure layout for Wireless Sensor Networks (WSN). In a WSN, the sensor nodes and its central node are located far apart to ensure good coverage over the concerning area. However, communication over long distance between the nodes consumes excessive energy from the battery powered sensors and reduces the lifetime...
In this paper, the problem of change detection from Multi-temporal remote sensing images is addressed. To that end, we present a measure of the observed change by combining the two related tasks. In their preliminary design stage, a method constructs difference image by wavelet-based fusing the results of differencing operation and log-ratio operation. Then, by taking into account the spatial-Neighborhood...
