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....

a我不是一个冲动的人,我希望有一个长期稳定的关系。所以,我不敢肯定,但是,我们尝试聊天,更多了解对方 I am not an impulse person, I hoped has long-term stability relations.Therefore, I do not dare to affirm, but, we attempt chat, understands opposite party[translate] ...
A transform of a function F (x) given by the function where K (x, y) is some function. Also known as integral transform. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc. Want to thank TFD for its existence? Tell a fri...
An integral which expresses the response of a linear system to some input in terms of the impulse response or step response of the system; it may be thought of as the summation of the responses to impulses or step functions occurring at various times. ...
An integral containing a delta function and a step function is a mathematical expression that combines the properties of both a delta function and a step function. It is often used in physics and engineering to represent a sudden change or impulse in a system. ...
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...
A phase function is an important characteristic of a scattering medium. A method to derive new analytic phase functions is proposed. The relation between a phase function and an angle-averaged single-scattering intensity, derived earlier [M. L. Shendelev
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 ...
