Anomalies of the omnipresent earth magnetic (i.e., geomagnetic) field in an indoor environment, caused by local disturbances due to construction materials, give rise to noisy direction sensing that hinders any dead reckoning system. In this paper, we turn this unpalatable phenomenon into a favorable one. We present Magicol, an indoor localization and tracking system that embraces the local disturbances...
The naming and routing schemes in traditional TCP/IP were designed in the days when processors were slow and memory was expensive. These schemes are weak in terms of the following aspects: inability to properly support mobility and multi-homing, creating complexity in the network configuration, making network measurement difficult, and so on. To avoid such weaknesses, we propose a new naming and routing...
When simulating the large scale air defense and antimissile system, the subsystem simulation must have the qualifications of both good effect and high efficiency. To meet the needs, this paper studied on the simulation method of the clutter suppression for the ground based radar in the large system particularly. It proposed building the database of the clutter suppression ratio through abundant simulations...
In this paper, we propose an intelligent system to help people create customized icons on touch sensitive mobile devices. Users can create their own icons from one or multiple drawings in an intelligent and interactive way. The system could automatically combine several hand-drawn sketches or drawings to create new complex icons. We also provide one recommendation function to assist the creation process...
This paper proposes a realistic data grid system named JobGrid to construct information platform for Chinese college graduates employment, which supports centralized transaction processing to ensure consistent, effective operation in data access, control, monitor and analysis, and distributed data management to provide heterogeneous data integration, conversion, exaction and export. JobGrid has implemented...
Mass of real-time data needs to be handled in the environment of networked manufacturing; especially, the real-time requirement of MES oriented spot management is much higher. Moreover, embedded real-time databases technology is a software technology which lies between spot data and real-time operating system. And it conforms to the production requirement of networked manufacturing on the side of...
