Pulses suffer from changes in time and space when it propagates through matter, like
the positive Group Velocity Dispersion (GVD) which increases the pulse duration and
disperses its components ,this appears a2s a result of the second derivative of phase with

shorten the pulse duration based on negative GVD.
The syntax is the spirit of language , the core of its movement, it is living heart.
And it is way of interpretation which is a pure mental manner . Taken by Arab Grammarians, so they gave it great effort in order to interpret the syntactic and morp
