At this point, it is helpful to summarize the definition of a few terms frequently used in the analysis of waves and their solutions: • A wave is the propagation in time t and space x of a disturbance in a medium. • A signal is a physical measure (e.g., traffic density k) ...
We identify an unusual regime of ultrafast nonlinear dynamics in which an optical shock wave couples to soliton self-compression, steepening the tail of the pulse, thus yielding self-compressing soliton transients as short as the field sub-half-cycle. We
The definition of b is linked to the fractal dimension, allowing for its interpreted as the fractal dimension df37 of D(ε). Upon substitution of b = df into Eq. (1), a simplified fractal damage evolution equation for rocks is derived. $$ D(\varepsilon ) = 1 - \exp \left[ {...

A high-definition uncompressed video data stream requires about 2 billion bits per second of data bandwidth. Owing to the large amount of data necessary to represent digital video, it is desirable that such video signals are easy to compress and decompress, to allow practical storage or transmissi...
According to one possible definition, quantization is a term used in transform coding for an approximating non-reversible mapping function commonly used for lossy compression, in which there is a specified set of possible output values, and each member of the set of possible output values has an...
Therefore, according to the definition of thermodynamic laws, the distribution state of crack initiation time, space, and intensity of AE sources in a fixed space can be defined as the AE entropy value, that is, the Qt value can be expressed as: $$Q_{t} = - \frac{{\sum\limits_{i ...
Applying the definition above, we can easily work out that in this case the compression ratio is 16 384/65 536 = 1/4, the compression factor is 4, and the saving percentage is 75%. Note the performance of a compression algorithm cannot of course be reflected by one such instance. In ...
Since there is no mechanical system to compress air for combustion, ramjet and scramjet engines rely on the high-kinetic energy from the high velocity freestream air and oblique shock waves to provide compression of the oncoming flow to suitable pressure, temperature and density; this is known as...
