Abstract (in Japanese) (See Japanese page) 
(in English) Assuming the change in the eigenfrequency is used for the bridge
structure diagnosis by wireless accelerometers, two data compression methods for energy-efficient communications, such as compressed sensing and our proposed selective sensing are evaluated by the probabilities to keep the frequency corresponding to the maximum power spectrum before
and after compression. The selective sensing replaces the sensing matrix by a Walsh matrix with a reduced number of row vectors to extract the targeted frequency band. Compressed sensing and our method can restore the original peak frequency with a probability of 70% and 90%, and reduce the power consumption by 50% and 40% respectively. Two systems
are exchangeable by swapping the sensing matrix by the other, and can be used together without any change in the receiver side. Thus an adaptive sensing can be achieved by exchanging the two methods.
