In neurosurgery, effects of deformation should be considered to avoid damaging brain tissues. The goal of this study is to develop an automatic path planner considering the deformation of brain tissues. This paper shows a scheme which combines FEM (Finite Element Method) and an optimization method for optimization of retraction in order to approach a deep part of a brain. Also, evaluations of two...
Adopting MPC to a fast changing system has always been a challenging problem due to the computational efficiency. As the equivalent aggregation strategy and the fast algorithm based on MPC proposed, the computational efficiency has been promoted greatly. This paper improves the fast algorithm combined with the equivalent aggregation strategy, and investigates the feasibility of adopting the fast algorithm...
Based on the principle of Mahalanobis distance discriminant analysis, the discrimination of influential degree of the different index to optimization of supporting programs for deep foundation pit is taken into account, using the weights obtained by the analytic hierarchy process to modify the Mahalanobis distance, by the new calculation method of covariance matrix, the weighted distance discreminant...
This article proposed a nonparametric test method by using Gaussian mixture model application idea for reference to evaluating the construction of index architecture. First use Gaussian mixture model to cluster analysis the index architecture. Second use rank correlation coefficient of nonparametric test method to select index architecture. Then determined the evaluate index architecture and guarantee...
