报告摘要:
In this talk, we show the stability of the inverse source problem for the three-dimensional Helmholtz equation in an inhomogeneous background medium. The stability estimate consists of the Lipschitz type data discrepancy and the high frequency tail of the source function, where the latter decreases as the upper bound of the frequency increases. The analysis employs scattering theory to obtain the holomorphic domain and an upper bound for the resolvent of the elliptic operator.

报告摘要:
Tool path planning is a crucial factor of computer-aided design and manufacturing (CAD/CAM). To generate suitable tool paths, the previous methods often transform the problem into local or global optimization methods to solve it, which leads to a long computational time. To achieve real-time planning, we try to propose an efficient neural network-based direct tool path generating method on B-spline surface. An intelligent neural network reparameterizes the workpiece surface based on the scallop height constraint.
