摘要: Feudal historical buildings with ritual elements are the basic scenes of many excellent games, However,researches on design methods for factual historical buildings in game are still out of demands both on precision and migration capability.Aiming at this problem,this paper deeply reflects on the semantic or ontology modeling of ritual elements and their integration model with the game engine and PCG.firstly,we comprehensively provides a ritual semantic model that can be used for automatic generation of ancient buildings in game historical scenes. Secondly,we designed the ritual semantic model to provide the loose coupling capability with the game environment and building system based on the ontology design pattern.Thirdly,through the analysis of the ritual semantic system of Style Lei, the experimental verification of the ritual semantic model is carried out, and the migration capability of the ritual semantic model is proved by comparison.The models and experiments proposed in this paper and even the analysis of the ritual elements in the Chinese style Lei building system can provide useful references for both game scene auto design and related researches.

摘要: In this paper, we propose a two-mode polarizable deflecting structure, as a new concept for bunch measurement and beam control. With two modes of HEM11 and HEM12 operating in the same structure on horizontal and vertical directions, respectively, the operation status can be switched between the two polarization modes. They can be operated simultaneously with two independent input power sources. With two-mode deflecting structure, the bunch distortion caused by the geometric wake-fields in the accelerating structure can be measured by one structure.

摘要: For developing the X-ray Free Electron Lasers test facility (SXFEL) at Shanghai Institute of Applied Physics, Chinese Academy of Sciences (SINAP), ultra-short bunch is the crucial requirement for excellent lasing performance. It is a big challenge for deflecting cavity to measure the length of ultra-short bunch, and higher deflecting gradient is required for higher measurement resolution. X-band travelling wave deflecting structure has features of higher deflecting voltage and compact structure, which has good performance at ultra-short bunch length measurement. In this paper, a new X-band deflecting structure is designed to operate in HEM11-2/3 mode. For suppressing the polarization of deflecting plane of the HEM11 mode, two symmetrical caves are added on the cavity wall to separate two polarized modes.
