In this paper,the problems of state feedback h control for a class of switched singular linear systems are *** constructing a novel switched Lyapunov functional and convex combinations techniques,a sufficient condition established in terms of strict linear matrix inequalities（LMIs） is presented such that the system is asymptotically stable and satisfies H *** explicit expression for the state feedback stabilization sub-controller and switching rule are *** merits of the proposed criteria lie in their less conservativeness and relative simplicity,in which the closed-loop system satisfies H performance at each point in whole state-space through switching,although each sub-system doesn't satisfy the performance and even is not asymptotically stable.A numerical example is provided to illustrate the validity of the proposed methods.

Based on the the Armstrong axioms, this paper aims to give a rule system applied to XML trees. The index tree algorithm based on the application of the XML normalization process eliminates some functional dependency and the transfer function depends, avoids updating anomalies and generates normalization struct tree NSTree. Through the trees in the XML NSTree marks in a tree structure and XML based on the index XSIT tree, the tree completes the XML document access operations.

In Multi-user and Multi-take environment, to ensure the normal operation of the system, we must to take measures in advance, to avoidance strategy or prevention strategy take place, The Banker's Algorithm is the famous method to avoidance strategy. In this paper, we studied the principle and data structure of Banker's algorithm, designed the concrete steps of the algorithm, and implement the algorithm by design a program. In the experiment, although we repeated changes the method of the loop algorithm, we Can still get the same conclusion. That is: no matter what loop order, the result that system is in or not in safe is the same. Because if in safe station, the system sometimes exist several security sequence, We adopted a different method, in which different sequence obtained。

To solve the convergence of urban and rural endowment insurance system is the key to the development of urban and rural endowment insurance system. Based on the analysis of the necessity of convergence of urban and rural basic endowment insurance system, five key issues are pointed out to achieve the convergence of urban and rural basic endowment insurance system. Countermeasures and suggestions to achieve the convergence and transformation of urban and rural basic endowment insurance system are emphasized from the aspects of making good preparation, narrowing differences of the level of endowment, implementing the "golden insurance project", directly incorporating migrant workers into "city residents insurance", paying attention to legislative protection and eliminating obstacles for the system and so on.

Social Media became one of the popular ways to release people's personal views on certain topics or personal bias, attitude to some thing or the current matters they are concerned about. Utilization of massages and posts generated by users in a group, a web community or a Social Media will help us to recognize the real demands and real viewpoints of users on some topics, and it will be a great helpful factor to improve services of system. The opinion of individual or group can be collected more easily online than offline; hereby the public opinion will be traced dynamically online because essentially the public opinion itself changes dramatically over time in social media and web communities. Many researchers analyzed and predicted hotspots social events by different methods based on contents from social media, such as Sina Weibo, a very hot Social Media in China, which got 5.03 billion users in 2012.
