An extended HLA multilayer federation integration architecture for multidisciplinary collaborative simulation

The development of complex products is essentially concerned with multidisciplinary knowledge. Running on Internet, integration based on muhilayer federation architecture and dynamic reuse of simulation resources are the major difficulties for complex product collaborative design and simulation. Since the traditional Run-Time Infrastructure （RTI） is not good at supporting these new requirements, an extended high level architecture （HLA） multilayer federation integration architecture （MLFIA）, based on the resource management federation （RMF） and its supporting environment based Service-oriented architecture （SOA） and HLA （SOHLA） are proposed, The idea and realization of two key technologies, the dynamic creation of simulation federation based on RMF, TH RTI, an extensible HLA runtime infrastructure （RTI）, used at Internet are emphasized. Finally, an industry case about multiple unit （MU） is given.

Heterostructure design of hydrangea-like Co_(2)P/Ni_(2)P@C multilayered hollow microspheres for high-efficiency microwave absorption

Structural design and elemental doping are research hotspots for the preparation of lightweight absorbers with high absorption performance and low filling ratio.Herein,a P-doped hydrangea-like layered compos-ite(Co_(2)P/Ni_(2)P@C)encapsulated with Ni-LDH was successfully synthesized by solvothermal method fol-lowed by phosphorization.The defects generated by P doping and the generation of multilayered nonuni-form interfaces enhance the dielectric loss induced by polarization.Simultaneously,the magnetic phos-phides induce magnetic loss and modulate the dielectric properties of the carbon matrix to enhance the conductive loss.The multilayered hollow structure of this composite promotes the scattering and reflec-tion of electromagnetic waves and optimizes the impedance characteristics.As a result,the multilayered hollow Co_(2)P/Ni_(2)P@C composite exhibits an optimum reflection loss value(RL)of–64.6 dB at 15.1 GHz with a thickness of 2 mm and a filler ratio of only 10 wt%.The radar cross-section(RCS)attenuation further demonstrates that the material can dissipate microwave energy in practical applications.Overall,this work provides an effective development strategy for the design of multilayered high-performance electromagnetic wave(EMW)absorbers doped with strongly polarized elements.

The Shizikou Gravitational Gliding Structure in the Three Gorges of the Yangtze River

A study has been made about the structural attribute of the NNW-trendingShizikou linear image belt in the head area of the reservoir of the Yangtze River Gorges and theevaluation of its crustal stability. On the basis of regional geological surveys and by making astructural analysis and a multidisciplinary study, it has been ascertained that the segment withthe best displayed image characteristics is marked by a gravity gliding structure with a multilay-er gliding fold type architecture. This paper also analyzes the medium conditions, slope struc-ture and dynamic setting for the formation of the structure system.

考虑层间滑动摩擦的书状层合板的弯曲响应与耗能

为了有更好的保护,较强的硬度和较好的柔韧性,所有的生命和植都有皮组织,同样,所有的书也都有封皮.本文将层间摩擦视为扰动,研究具有层间滑动摩擦的精装书状层合板.对于准静态问题,针对三点支撑板弯曲响应和能量耗散进行了详细分析.我们的数值研究表明,就弯曲响应言,精装书的封皮比书芯层更重要;而对于耗能,摩擦导致在每个加载和载周期内产生很大的能量耗散.本研究的核心目标不仅是预测书本状板弯曲变形,而是用这一个代表性的案例,以期望找到有关具有层间滑动摩的多层结构的普遍行为.
