In this paper, we propose a novel system to localize a sound source in any planar direction using only two microphones. In our system, the two microphones are asymmetrically placed on a sphere, thus, 1) the diffraction by the sphere and the asymmetrical arrangement of the microphones give the localization cue including the frontback judgment, and 2) unlike the dummy head system, no previous mea...

Three meanings of “information” are distinguished: “Information-as-process”; “information-as-knowledge”; and “information-as-thing,” the attributive use of “information” to denote things regarded as informative. The nature and characteristics of “information-asthing” are discussed, using an indirect approach (“What things are informative?“). Varieties of “informationas-thing” include data, text...

Vehicular Ad Hoc Network (VANET) has been drawing interest among the researchers for the past couple of years. Though ad hoc network or mobile ad hoc network is very common in military environment, the real world practice of ad hoc network is still very low. On the other hand, cloud computing is supposed to be the next big thing because of its scalability, PaaS, IaaS, SaaS and other important c...
