A signal's propagation velocity is inversely proportional to the square root of the effective, average Dk of the medium surrounding each half of the differential pair (FIGURE 2).
In this sense, results in the literature have indicated that the acoustic wave propagation velocity increases with age, especially until the transition period from juvenile to adult wood (Grabianowski et al.
Term Definition Bone mirror Relatively featureless region of a fractured bone surface near the fracture initiation site Bone hackle Angular or rounded ridges aligned in the direction of propagation resulting from increasing crack speed and instability Arrest ridges Large raised ridges or peaks perpendicular to the direction of crack propagation resulting from drastic changes in crack propagation velocity Cantilever curl A curved lip that occurs just before total fracture of a bone loaded in bending
The underwater propagation velocity is a function of some things as temperature, pressure and salinity of seawater, which is written as Equation (5) [2], where c shows the propagation velocity of sound in m/s; T shows the temperature in degree Celsius; S represents the salinity in parts per thousand, and D is the depth in meters.
it will be capable of conducting common-midpoint (cmp) surveys to gain an understanding of propagation velocity through a given substrate.
The interface pressure, [p.sub.I], as well as its propagation velocity, [u.sub.I], is obtained as a solution to the Riemann problem.
Two important parameters are generally used for evaluating chemical reaction mechanisms, ignition delay time and flame propagation velocity. In combustion, ignition delay is a ubiquitous phenomenon and refers to the fuel/air mixture not immediately igniting and burning when the mixture temperature is higher than the ignition temperature.
In the second section of the paper we infer the expression of the wave propagation velocity in a fluid when the density and the pressure vary adiabatically.
[4] used SHPB [5] to study the crack propagation characteristics and propagation velocity of plate-shaped specimens with round and oval holes.
To verify the validity of the CpLip1 SAW device system as a biological function-oriented odor sensor, we experimentally observed the propagation velocity of the SAW device with different odorant molecules bound to the Cp-Lip1 protein.
As the fuel/air mixture became leaner, the burning time increased due to the slower flame propagation velocity at lower equivalence ratio.
This is guaranteed by the constant propagation velocity of light in the ether and the Lorentz transformation (LT), as shown by Maxwell's luminiferous ether theory and confirmed by two-way speed of light measurements in vacuo.
