2014年美国联邦社会保险（The Federal Old -aged and Survivors Insurance and Federal Disability Insurance，OASDI）信托基金年度报告比往年来得更晚一些，法定在4月1日发布的报告直到7月28日才发布，这已经是奥巴马政府时期的第5次爽约。实际上奥巴马政府时期美国的OASDl年度报告从来就没有准时过，推迟发布已经成为其习惯（最晚的2010年度报告到8月5日才发布）。
摘要：
The proposed vehicle information management system based on Struts architecture is designed for the management of stock, customer, and financial information for used vehicle dealerships. Struts architecture and UML extension mechanism are applied to provide a safe and efficient MVC framework, to reduce the complexity of authorization management, to enhance the system stability, to realize the entire sales data sharing, and to support the security tactics of port in more flexible way. The product not only tracks and reports all information relevant to vehicle acquisition, preparation of vehicle for sale and disposal of vehicle but also provides management information regarding customers, suppliers, salesman, and vehicle financing arrangements.

摘要：
Importance sampling is always used to modify the probabilities for rare event occurrences that govern the outcomes of the simulation in a way that allows for low probability events to occur more frequently. In this paper, importance sampling is applied to accelerate the simulation for coherent risk measure based on generalized rare scenarios. Firstly, we show how to combine importance sampling with ranking and selection method provided by Lesnevski, Nalson and Staum to accelerate simulation coherent risk measure directly. Secondly, recursive Robbins-Monro type algorithm is introduced to estimate the parameters of optimal sampling distributions. Finally, computational efficiency of simulated confidence intervals for coherent risk measure is discussed under three simulation settings: Asian call option, Asian options on partial average, down-and-in barrier call option.
