Convergence of Multilevel Stationary Gaussian Convolution
Simon Hubbert, Jeremy Levesley
It is well-known that polynomial reproduction is not possible when approximating with Gaussian kernels. Quasi-interpolation schemes have been developed which use a finite number of…
Multilevel sparse grids collocation for linear partial differential equations, with tensor product smooth basis functions
Yangzhang Zhao, Qi Zhang, Jeremy Levesley
Radial basis functions have become a popular tool for approximation and solution of partial differential equations (PDEs). The recently proposed multilevel sparse interpolation wit…
Pseudo-Outcrop Visualization of Borehole Images and Core Scans
Evgeny M. Mirkes, Alexander N. Gorban, Jeremy Levesley +2
A pseudo-outcrop visualization is demonstrated for borehole and full-diameter rock core images to augment the ubiquitous unwrapped cylinder view and thereby to assist non-specialis…
