5.2 Estimated blocked forces at passive-side EDU mounts The results obtainable with in-situ TPA can be improved by defining the connection interface at the passive-side mounts. This side of the mounts is strongly coupled to the vehicle body, which allows the coupled transfer functions (H24,AB)...
laying the foundations for Mark Weiser's concept of ubiquitous computing, which he sees as the "availability of computers throughout the physical environment, virtually, if not effectively, invisible to the user" [42,43]. Cuffet al.describe mobile devices as "passive sensors...
describe mobile devices as "passive sensors that can silently collect, exchange, and process information all day long" [41]. This style of sensing is called 'urban sensing' due to its suitability for large urban areas with high population density, but could be implemented in any environment. ...
Nonmilitary uses of sonar include fish finding, depth sounding, mapping of the sea bottom, Doppler navigation, and acoustic locating for divers. A major step in the development of sonar systems was the invention of the acoustic transducer and the design of efficient acoustic projectors. These ...
