G/S mode is a brand new spatial data access mode which is especially suitable for spatial information accessing through network. By introducing the software testing theory, a software performance testing on the spatial information network accessing was conducted between the Google Earth based on G/S mode and the Google Maps based on B/S mode. The advantages of G/S mode on the spatial information network...
The performance of non-preemptive M/M/l queuing system with two priority is newly proposed. Though this kind of queuing system is researched by many scholars, the performance indexes are often approximate. The complementary variable method is also used to make vector Markov process and analyze the state-change equations of the queuing system. With Rouche theorem to analyze the coefficient of the generating...
