Ultrasound velocity was used to study developmental changes of stem tissues in cereal plants. The velocity of longitudinal waves, MHz, was measured with pulsed through-transmission method in axial direction of stem. The v determined on the same stem position varied from m/s to m/s as the plants grew and matured. This article evaluates the velocity and acoustic fields of an isothermal single jet discharging from a circular mm conical nozzle at three different Mach and Reynolds numbers of (Re = 2.   At present computer-controlled sound velocity measurement systems allow many experimental investigations and control procedures to be run routinely. However, the evaluation of sound velocity profiles in terms of molecular and microscopic sample properties remains a challenging task, when only single-frequency or narrow-bandwidth data are by: Application of a Beamforming Technique to the Measurement of Airfoil Leading Edge Noise Article (PDF Available) in Advances in Acoustics and Vibration () February with Reads.

Axial room modes from. The first edition of the Water Measurement Manual () had a distribution of 11, copies and was compiled from the Bureau of Reclamation (Reclamation) publication Manual for Measurement of Irrigation Water (). This previous manual had five earlier editions beginning in and extending to

Study on measurement accuracy of active optics null test systems based on liquid crystal spatial light modulator and laser interferometer Paper Time: PM - PM. | Centrifugal Compressors | Figure shows the pressure, velocity, and total enthalpy variation for flow through several stages of an axial compressor. It is important to note here that the changes in the total conditions for pressure, temperature, and enthalpy occur only in the rotating component where energy is inputted into the system. When low-energy photons and high-energy electrons are involved the inverse effect occurs. This effect results in an increase of the wavelength of the radiation involved, and it was first discovered in , resulting in a share of the Physics Nobel Prize for its discoveror. Histotripsy is a cavitation-based ultrasound therapy that mechanically fractionates soft solid tissues into fluid-like homogenates. This paper investigates the feasibility of imaging the tissue elasticity change during the histotripsy process as a tool to provide feedback for the by:
