Two anatomic types can be distinguished, the first extrapelvic AVM (tissular malformations), the second intrapelvic AVM more often troncular malformations. The intrapelvic AVM have a particular angioarchitexture and are developed between the anterior branches of the internal iliac artery and a venous...

The authors consider the method of boundary integral equations for the solution of the third boundary value problem for Helmholtz' equation in an exterior domain. It is well known that in the simplest formulation the integral equation may not be uniquely solvable although the boundary value problem...

The method of polarized traces for the 2D Helmholtz equation (the offline part), and incomplete Green's formulas are used to propagate interface data in a sweeping fashion, as a preconditioner inside a GMRES loop... L Zepeda-Nú?Ez,L Demanet - 《Journal of Computational Physics》 被引量: ...
The adjoint problem is formulated, the UGFs for all possible cases of boundary conditions for the Vector Helmholtz equation are defined and their symmetrical properties, as well as the assumptions under which these ones hold, proved. The analysis begins with the examination of the basic problem of...
A construction is described for the asymptotic behavior of Green's function G(x, x', λ) of the scattering problem for the Schrdinger equation as x →∞ , which is uniform with respect to x'.doi:10.1007/BF01084486M. M. Skriganov...
The static ˆ−1 ′ ′ ′ ′ regime of the Klein Gordon equation—which also leads L{r} = G(r ,r) (r ) w(r ,r)dr , (9) r′ to the Yukawa potential—also follows a similar behavior, as its associated Green function in 2D is K (µr), satisfy- 0 conditioned by the ...
equation parameterization and precipitation scaling influence the critical temperature threshold to some extent, yet within the range set by the two independent models. However, the qualitative behaviour does not change and a recovery after an initial loss is seen for all combinations for small ...
