The Catastrophe Map of a Two Period Production Model with Uncertainty

This paper shows existence and efficiency of equilibria of a two period production model with uncertainty as a consequence of the catastrophe map being smooth and proper. Its inverse mapping defines a finite covering implying finiteness of equilibria. Beyond the extraction of local equilibrium information of the model, the catastrophe map renders itself well for a global study of the equilibrium set. It is shown that the equilibrium set has the structure of a smooth submanifold of the Euclidean space which is diffeomorphic to the sphere implying connectedness, simple connectedness, and contractibility.

室内RFID网络跟踪算法研究

随着RFID技术的不断发展和应用,基于RFID技术的定位系统已成为当前研究的热点问题。详细介绍了一种RFID定位算法,以阅读器网络为研究对象,存储在系统中的阅读器拓扑结构为母板,通过收集到的跟踪向量与母板匹配,寻找最佳路径。实验表明,RFID网络跟踪算法在大空间中能够准确地跟踪物体、检测阅读器工作状态;当阅读器出现故障时,算法仍能对物体跟踪定位,具有较好的鲁棒性。
