Length and Velocity Scales of Breaking Waves

Status of Relativity with observer-independent length and velocity scales

I have recently shown that it is possible to formulate the Relativity postulates in a way that does not lead to inconsistencies in the case of space-times whose structure is governed by observer-independent scales of both velocity and length. Here I give an update on the status of this proposal, including a brief review of some very recent developments. I also emphasize the role that one of the...

Comparison of relativity theories with observer - independent scales of both velocity and length / mass

There are now in the literature two proposals of relativity theories with observer-independent scales of both velocity and length/mass: one, which we here call “DSR1”, proposed by Amelino-Camelia in gr-qc/0012051,hep-th/0012238 and one, which we here call “DSR2”, proposed by Magueijo and Smolin in hep-th/0112090. We argue that a key aspect of such theories are the kinematical conditions for par...

Breaking Wave Velocity Estimation

determination of velocity of seismic waves and upper crustal velocity model in shiraz seismological network

iran is located between two lithospheric plates (euroasia, arabian) and these two plates converge toward each other with a velocity of 25 mm/yr rate. shortening that produced from this convergence with makran subductin shows faulting and folding in zagros orogenic belt, alborz and kopedagh in north and sliding in sum strike slip faults with north-south trend in central iran. the nw-se trending ...

The Effect of Dynamic Permeability on Velocity and Intrinsic Attenuation of Compressional Waves in Sand

Stress waves contain useful information about the properties of porous materials; they can be recovered through different non-destructive testing methods such as crosswell, vertical seismic profile, borehole logging as well as sonic tests. In all these methods, it is crucial to assess the effects of frequency on wave attributes including velocity and intrinsic attenuation. The dependency of per...
