Ultrasound elastography can be classified into 3 types: (1) those that apply a quasistatic compression and estimate the resulting components of the strain tensor [ 12– 18]; (2) those that apply low-frequency vibration with ultrasound Doppler detection of velocities of perturbed reflectors [ 19– 21]; and (3) those that use acoustic-radiation force [ 8, 9, 22].
A calorimetric sensor for detection of gas velocity and flow direction was constructed by sacrificial porous silicon micromachining technique.
Equipped with 2.5 m optics and a field of view of ±30°, the EUSO telescope can also be utilised for the detection of high velocity fragmentation debris in orbit near the ISS.
It is not conducive for the detection of low velocity target like low-speed ship.
Instead, we assumed that Doppler wire acquired APV offers a good linear relation to blood flow in proximal LCx segments [ 19] and thus can be used as a surrogate marker of blood flow, mainly for detection of flow velocity changes assuming nonsignificant changes in a vessel diameter [ 20].
Seismological detection of low-velocity anomalies surrounding the mantle transition zone in Japan subduction zone.
A new smart polymer nanocomposite layer, based on semiconductor Cu2S nanoparticles embedded into an amorphous polystyrene matrix, was developed for the detection of low-velocity impact damage on composite structures.
It is thus evident, that if the animals used the detection of instantaneous velocities, instead of f* A, the result of the Adibi et al. experiments would have been the same.
These peaks, happening in all three noise scenario, are good references for the ability of proposed detection in extraction of velocity.
We designed, fabricated and evaluate the novel air flowmeter with corrugation structure for the detection of low air velocity.
Detection of high flow velocity (~51 cm/s) present in the porcine carotid artery was obtained by phase unwrapping techniques and compared to numerical simulation, taking into consideration flow profile distortion by the eccentrically positioned imaging catheter.
