Eclipsing binaries (EBs) play an important astrophysical role in studying stellar properties and evolution. By analyzing photometric data in the LAMOST Medium-Resolution Survey field, RA: $23^h$$01^m$$51.00^s$, Dec: +34$^\circ$36$^\prime$45$^{\prime

Aggregation algorithm for MPLS multicast flows based on bidirectional shared tree

Autor: LI Ling-zhi, ZHU Yan-qin, YANG Zhe

Publikováno v: Tongxin xuebao, Vol 31, Pp 64-71 (2010)

Scalability is the mainly problem that impedes the extensive deployment of multicast in MPLS networks. An aggregation algorithm for multicast flow based on bidirectional shared tree was proposed in order to resolve the problem. The aggregated degrees

Extremely low mass ratio contact binaries -- I. the first photometric and spectroscopic investigations of ten systems

Autor: Li, Kai, Gao, Xiang, Liu, Xin-Yi, Gao, Xing, Li, Ling-Zhi, Chen, Xu, Sun, Guo-You

The photometric and spectroscopic investigations of ten contact binaries were presented for the first time. It is discovered that the mass ratios of all the ten targets are smaller than 0.15, they are extremely low mass ratio contact binaries. Seven
