IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2021 The instantaneous frequency (IF) image is proposed in this work. It is obtained by the differentiation of the instantaneous phase (IP) image, which in turn is calculated by replacing the amplitude information with the IP in the delay-and-sum beamforming.

Recasting the (Synchrosqueezed) Short-Time Fourier Transform as an Instantaneous Spectrum
Entropy, 2022 In a previous work, we proposed a time-frequency analysis called instantaneous spectral analysis (ISA), which generalizes the notion of the Fourier spectrum and in which instantaneous frequency is utilized to the fullest extent.

Instantaneous interaction in massive gravity [PDF]
, 2008 In general relativity, the instantaneous contributions to the gravitational potentials cancel each other in observable, leaving the theory free of physical instantaneous interactions. In models where these subtle cancellations are spoiled by the presence

Dynamic Tire Pressure Sensor for Measuring Ground Vibration
Sensors, 2012 This work presents a convenient and non-contact acoustic sensing approach for measuring ground vibration. This approach, which uses an instantaneous dynamic tire pressure sensor (DTPS), possesses the capability to replace the accelerometer or directional
