Every person or family will face a series of important expenses. In order to avoid shocks from these expenses for individuals or families, people will probably have precautionary saving incentives which influence their strategic asset allocation. This paper reviews domestic and foreign literatures about asset allocation and precautionary saving. This paper proposes a new asset allocation model framework...
This brief paper formulates and studies a simple yet general weighted evolving network model. In contrast with the well-known Barrat-Barthélemy-Vespignani (BBV) locally weighted evolving model, this model can allow the flows to be widely updated. We provide both analysis and simulation of the network characteristics for such weighted model, and all the theoretical predictions are successfully contrasted...
It is well known that in Barrat-Barthélemy-Vespignani (BBV) model, the rearrangement of weights is local. In this paper, we present a novel weighted evolving network model that allows the flows to be widely updated. This model gives power-law distributions of degree, weight and strength, as confirmed in many real networks. Particularly, the exponents are nonuniversal and depend on a parameter that...
IEEE 802.11 protocol is widely used in Wireless Local Area Networks (WLAN) for its high data transmission rates. The formation flying satellite system has a short inter-satellite distance, which is similar to WLAN. It may be a good choice to apply IEEE 802.11 protocol in inter-satellite communication to increase throughput. However inter-satellite distance is longer than what desired by WLAN, so IEEE...
