A study of the radiative transfer equation using a spherical harmonics-nodal collocation method

Capilla Romá, Maria Teresa; Talavera Usano, César Félix; Ginestar Peiro, Damián; Verdú Martín, Gumersindo Jesús (Elsevier, 2017)

[EN] Optical tomography has found many medical applications that need to know how the photons interact with the different tissues. The majority of the photon transport simulations are done using the diffusion approximation, ...
Approximation of The Neutron Diffusion Equation on Hexagonal Geometries Using a h-p finite element method

Fayez Moustafa Moawad, Ragab (Universitat Politècnica de València, 2016-06-07)

[EN] The neutron diffusion equation is an approximation of the neutron transport equation that describes the neutron population in a nuclear reactor core. In particular, we will consider here VVER-type reactors which use ...
Computation of the C5G7 neutron transport benchmark using a spherical harmonics-nodal collocation method

Capilla Romá, Maria Teresa; Talavera Usano, César Félix; Ginestar Peiro, Damián; Verdú Martín, Gumersindo Jesús (International Center for Numerical Methods in Engineering (CIMNE), 2017-07-05)

[EN] The spherical harmonics method is applied to the angular dependence of the neutron transport equation, obtaining a finite approximation known as the PL equations, that are rewritten as a vector-valued second order ...
Detection of infant`s cranial deformation based on spherical harmonics 3D modeling

Grieb, Jonas Imanuel (Universitat Politècnica de València, 2021-04-01)

[EN] 3D modeling is increasingly being used for the detection of infant's cranial deformation, where among other methods the deformation has been evaluated by the comparison of the cranium to an ideal cranial shape, ...
Nodal collocation method for the multidimensional PL equations applied to neutron transport source problems

Capilla Romá, Maria Teresa; Talavera Usano, César Félix; Ginestar Peiro, Damián; Verdú Martín, Gumersindo Jesús (Elsevier Masson, 2016-01)

A PL spherical harmonics-nodal collocation method is applied to the solution of the multidimensional neutron source transport equation. Vacuum boundary conditions are approximated by setting Marshak's ...
Spherical harmonics to quantify cranial asymmetry in deformational plagiocephaly

Grieb, Jonas; Barbero-García, Inés; Lerma, José Luis (Nature Publishing Group, 2022-01-07)

[EN] Cranial deformation and deformational plagiocephaly (DP) in particular affect an important percentage of infants. The assessment and diagnosis of the deformation are commonly carried by manual measurements that provide ...
