T] is narrow compared with the slit width or ideally close to a Dirac delta
function, then the SRF approximates to a triangle function with a bandwidth (FWHM, Full Width at Half Maximum) equivalent to a in image plane coordinate.
Of course, if [alpha] is the Dirac delta
function, (2) reduces to the classical constitutive equation of a hyperelastic material.
The result indicates that the radio emissions by the nonlinearly oscillating neutron star are periodically pulse-like radiation with the Dirac delta
shape, which is consistent with the general observations of pulsars.
where [delta](x) is the Dirac delta
function, and f is a given function such that [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] for some positive constant c.

New to this edition is coverage of the application of Laplace transforms, the Dirac delta
function, and the Heaviside function; the Cherkaev, Lurie, and Milton (CLM) stress invariance theorem; and recent developments in thermoelasticity.
