This paper sets out to present a numerical procedure that solves Poisson’s equation in a spherical coordinate system. To discretize this equation, integration techniques at the interfaces between ...

Abstract: Formulas are derived giving the vector potential and the magnetic field components of a general coil of rectangular cross section and constant winding density. The solution is given in a ...

Abstract: Seismic advance detection is a method for detecting complex geological formations in a tunnel face, which is crucial for the safe construction of tunnel projects. During the process of 3-D ...
