An exact analytical time-domain Green’s function is obtained for the van Wijngaarden wave equation when two of the constant coefficients satisfy a certain equality. This analytical expression enables numerical assessments demonstrating that lossy t

We investigate the use of spatial frequency filtering to detect specific features and classify images without reconstructing a full image. Based on interferometric Fourier-domain imaging, filtering the spatial frequency information amounts to a data

Exact and approximate analytical time-domain Green’s functions that describe linear with frequency attenuation are presented for the Chen-Holm space-fractional wave equation. These exact and approximate time-domain Green’s functions contain a Cau

Solutions to the inviscid Burgers equation are numerically computed with the discontinuous Galerkin method with basis functions up to 16th order. Simulation results show that shock waves are effectively modeled and that in the absence of filtering, s
