The shooting and bouncing ray (SBR) method is highly effective for solving the electromagnetic scattering problems. This paper introduces the octree based SBR-PO method, due to the fact that traditional SBR method is not fast enough for scattering prediction for electrically large target. Using the octree structure to rebuild the target model and process ray tracing based on this technique can obtain...
In this study, we firstly take good advantage of SEER Public-Use Data to predict breast cancer recurrence using data mining techniques. The SEER Public-Use Data 2005 is used in this research. We presented a new data pre-classification method and firstly find a possible solution to discover the information of breast cancer recurrence of SEER data. After the preprocessing of the dataset, we investigate...
