This paper designs and implements a new indoor location system based on a novel type of WIFI fingerprint by fully considering the interference of signals affected by different mobile orientation and user's body. Simulation results show that our method is better than traditional methods in the aspect of positioning accuracy and resolution.
Geographical centralized e-commerce has a lot of defects. Based on the characteristics of P2P and Web Services technology, a decentralized e-commerce architecture is proposed in this paper, which can solve the problems such as the difficulties of resource reorganization, cross-platform, database maintenance and so on, which can hardly be settled in existing geographical centralized e-commerce. So...
In order to enhance the efficiency of software simulation system and shorten the running periods of system, the technique of Sybase Open Client Component is introduced here and a read-write method for matrix data is proposed, Write-Multi-Image method is given finally through experiments and analysis. Sybase Open Client interface technique was introduced firstly, and then the access-control structure...
