These advantages are illustrated by examples relating to the propagation of an acoustic wave in a material displaying hereditary viscoelasticity defined by an ε-γ-kernel, and by the damped vibrations of an impulse-excited two-dimensional vibrator.S.I....

Section 8.11 is concerned with asymptotic properties, while Section 8.12 is virtually separate from the earlier part of the chapter and is concerned with impulse responses, i.e., the behaviour of the system in the time, rather than frequency, domain. This description is taken up again in ...

The Dirac delta function squared, denoted as δ2(x), is a mathematical function that represents a point mass at the origin with an area of 1. It is often used in physics and engineering to model impulse or point loads. What is the value of δ^2(x)?

it is a wave analog (in the frequency domain) of the Poisson equation (the case k = 0), which has in the right-hand side some function f(r) responsible for the spatial distribution of charges (or sources). This ″impulse response″ of the Helmholtz equation is a fundamental tool for...
