Volcano tomography provides valuable information concerning the internal structure of a volcano. During times of increased volcano activities, real-time images of the interior would allow seismologists to better understand volcanic dynamics. However, real-time tomography requires spatial coverage of the volcano utilizing large number of seismic sensors. The current broadband seismic sensors used in...
Owing to the rich processing, multi-modal sensing, and versatile networking capabilities, smartphones are increasingly used to build data-intensive embedded sensing applications. However, various challenges must be systematically addressed before smartphones can be used as a generic embedded sensing platform, including high power consumption, lack of real-time functionality, and user-friendly embedded...
As a key technology of home area networks in smart grids, fine-grained power usage monitoring may help conserve electricity. Several existing systems achieve this goal by exploiting appliances' power usage signatures identified in labor-intensive in situ training processes. Recent work shows that autonomous power usage monitoring can be achieved by supplementing a smart meter with distributed sensors...
