We note that, although the use of IGA collocation for Bernoulli–Euler beams and Kirchhoff plates is new, collocation methods have a long history, in particular for the ...

Application of Gaussian beam migration to VSP imaging

WebSeismic-imaging algorithms can be divided into two broad categories: integral methods (e.g., Kirchhoff methods) and wavefield-continuation methods. Integral methods can be described by simple geometrical objects such as rays and summation surfaces. Wavefield-continuation methods can yield more accurate images of complex subsurface structures.
