The sparsity of the input signal is important for compressive sensing (CS) reconstruction in CS system. In this paper, we establish an optimized truncation model to determine the number of the sparsified coefficients to be truncated in CS acquisition according to the sampling rate. The proposed truncation model suits for signals of any dimension. With the truncation model, the sparsity of the signal...
This paper describes about experimental verifications on the cricket's response against frequent interactions and how it changes in time development. In order to investigate behavior modification, we took the approach to utilize automated interaction systems with a robotic agent and observe the reactions of the male cricket. The robotic agent robes cricket's pheromone and is controlled by designing...
This paper describes about on-line underwater image gathering utilizing stationary sensor node and movable sensor node. We consider applying them to investigate the conditions of marine ecosystem around coral leaf at Okinawa, Japan. The framework of our proposed underwater image gathering system is introduced. Current developments on stationary and movable sensor node prototypes are also described...
