In our last article, we introduced four integral operators in the boundary integral equations in BEM. Among them, the two compact operators \(T_K\) and \(T_{K^{*}}\) are of the second Fredholm type and have strong singularity when the model geometry…

Circles and Pi Introduction id: intro-1 For as long as human beings exist, we have looked to the sky and tried to explain life on Earth using the motion of stars, planets and the moon. The Greeks were the first to discover that all celestial objects…
