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...
RGF is a finite-difference frequency-domain (FDFD) code in MATLAB that uses the recursive Green's function method to solve the scattering matrix (or a portion of it) of a user-specified two-sided structure. Specifically, it solves the scalar Helmholtz equation [∇2+k2εr(r)]ψ(r)=0 ...
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 ...
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 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...
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 ...
Additionally, a decreasing trend in the Cdl value with increasing inhibitor concentration is observed (Table 2), which is in accordance with the famous Helmholtz equation (Eq. 8). According to Eq. 8, a decrease in the permittivity (εo), the local dielectric constant (ε), and the exposed...
function considers differences with the observed surface velocity field. To avoid flow instabilities during transient runs, the oscillations occurring in the inverted 2D viscosity field are eliminated by defining areas of equal viscosity. The geometry evolution of the glacier is calculated deploying the ...
A case study of an installed, central-station (no storage), utility-intertie photovoltaic (PV) system in Sede Boger, Israel (latitude 30.9掳N), is presented. This PV system was constructed with 189 polycrystalline silicon solar cell modules mounted on inexpensive, horizontal north-south axis ...
Therefore the Green functions of the Helmholtz equation in the IHSs, which satisfy the impedance boundary condition on the ground surface and the Sommerfeld condition, must be computed efficiently and exactly for various source-receiver positions and various possible values of the ground surface ...
