As stated above, this is a superposition of screened 1 / " r " functions, weighted by the source function " f " and with " ? " acting as the strength of the screening.
22.
The function " s " ( " x ", " t " ) is often called the source function because in practice it describes the effects of the sources of waves on the medium carrying them.
23.
Even though we have neglected the frequency-dependence of parameters such as S, we know that it is a function of optical depth therefore in order to integrate this we need to have a method for deriving the source function.
24.
Note that there is an open source function in the office of the Director of National Intelligence, which may be taking over certain legal interviews in the US that previously were the Domestic Contact Division ( or Domestic Contact Service ).
25.
Therefore, when " ? " is very small, the solution approaches that of the unscreened Poisson equation, which, in dimension n = 3, is a superposition of 1 / " r " functions weighted by the source function " f ":
26.
In the more general case, any nonhomogeneous source function in any variable can be described as a forcing function, and the resulting solution can often be determined using a superposition of linear combinations of the homogeneous solutions and the forcing term.
27.
The maker of VanHeusen, Izod and Bass clothing and shoes also said it plans to reposition its Gant brand, which will involve focusing on new and upgraded products and consolidating worldwide design and sourcing functions . ( PVH US Equity CN)
28.
Where \ Delta is the Laplace operator, " ? " is a constant that expresses the " screening ", " f " is an arbitrary function of position ( known as the " source function " ) and " u " is the function to be determined.
