We consider the inverse problems of simultaneously determining two unknowns: the wave propagation velocity and the memory of a layered medium. To find them, we use the data of two observed fluctuations on the domain boundary. Estimates of the solution stability and uniqueness theorems for the ...
37 Light travels at a speed which is about a milpon times faster than the speed of sound. In one second, pght travels about 300,000 km. But sound travels only 344m. You can get some idea of his difference by watching the start of a race. If you stand some distance away from the...
(适应)constant changes in time.That is why they often look fifty years old when they are only forty.This adjustment to sudden changes causes all sorts of problems.Businessmen who travel from one side of the world to the other in one day are told never to make important decisions during ...
In general, any non-canonical k-essence model has an evolving speed of sound. One has to choose a model in such a way that the sound speed is always subluminal because we do not expect any information to propagate faster than the speed of light in a vacuum. Also, the sound speed has...
Understanding this is very very individual and it depends on each of us how to interpret it.This is my own interpretation: From the 2nd strophe above, he got the chance in a form of wind, which carry him far away to the endless distance by the speed of sound.The point is, that the...

Concorde flew faster than the speed of sound.It could carry 100 passengers.So was Concorde the best plane that has ever been built?For 27 years,passengers travelled across the Atlantic on this jet plane.Most of them were businesspeople and film stars,royalty,rock stars and sporting heroes.Flyi...
Processing of spatial sounds in the impaired auditory system First, the benefit from early reflections (ER's) in a room was determined using a virtual auditory environment. ER's were found to be useful for speech intelligibility, but to a smaller extent than the direct sound (DS). The .....
The Role of Fracture Dynamics in Kimberlite Pipe Formation This provides the necessary low viscosity for the crack to accelerate. The crack becomes unstable, and the speed approaches the shear velocity of sound as the crack breaks through the earth's surface. The main problem in this model .....
