In this paper, a measurement method for cross-sectional temperature distributions is considered. A novel method based on an acoustic computed tomography (CT) technique is proposed. Specifically, the temperature distributions are estimated using the t

This paper presents the fundamental principles of a high-precision RF time-of-flight (ToF) measurement method based on the vernier effect, which enables the improvement of time measurement resolution, for accurate distance measurement between sensor

In centralized range-based localization techniques, sufficiency of inter-node range information received by the base station strongly affects node position estimation results. Successful data aggregation is influenced by link stability of each connec

In this paper, we find conditions that reconstruction of temperature distribution gets worse when the ultrasonic transceivers (transmitter and receiver) are arranged flexibly. We discovered the minimum number of the ultrasonic transceivers required f
