Emergency decision itself is a scientific and complicated process, clarifying scarcity factors' influence on individual decision-making risk behaviors can help decision-making makers make a scientific decision. From scarcity factor in emergency, this study analyzes the decision-making risk behaviors, then puts forward the research hypotheses, Based on the questionnaire data, the research hypotheses...
The pricing of CDS has become a hot issue after the U.S. subprime mortgage crisis erupted. For BDS with different reference assets, it is important to define the default correlation between the assets. Using copula functions to describe the dependent structure between the assets has some advantages and becomes popular recently. In the paper, we develop a BDS pricing model using the copula function...
We focus on wireless sensor networks (WSNs) that perform data collection with the objective of obtaining the whole dataset at the sink (as opposed to a function of the dataset). In this case, energy-efficient data collection requires the use of data aggregation. Whereas many data aggregation schemes have been investigated, they either compromise the fidelity of the recovered data or require complicated...
Although wireless sensor networks (WSNs) are powerful in monitoring physical events, the data collected from a WSN are almost always incomplete if the surveyed physical event spreads over a wide area. The reason for this incompleteness is twofold: i) insufficient network coverage and ii) data aggregation for energy saving. Whereas the existing recovery schemes only tackle the second aspect, we develop...
As a burgeoning technique for signal processing, compressed sensing (CS) is being increasingly applied to wireless communications. However, little work is done to apply CS to multihop networking scenarios. In this paper, we investigate the application of CS to data collection in wireless sensor networks, and we aim at minimizing the network energy consumption through joint routing and compressed aggregation...
In the circumstances of market economy, it seems fair to claim that debt is not just a financing instrument, but more importantly, an administrative instrument. Through the application of regression analysis, and taking all the A-stock listed companies on China's stock market during 2001 to 2006, it can be concluded that excessive investment activities exist in China' s listed companies, and leveraged...
