    Traditional search engines are keywordbased retrieval. However, the keywords of a document may not be related with the document, and the related documents may also not explicitly contain this keyword. Using ontology technology, search engine based on semantic Web could semantically describe the keywords. When receiving a user’s request of query, system executes logical reasoning on the ontology already created and sends the result of logical reasoning to the traditional engine. The system returns the result of search to user at last. Comparing with the traditional search engine, the search engine based on semantic Web can effectively improve the coverage rate and precision rate.

    Though state PI control has been put forward for several years, it has not been applied to rotation speed control of hydraulic turbine. Based on state PI control theory, state PI controller of the traditional hydraulic turbine regulation system is obtained from state feedback model of the hydraulic turbine control system. Moreover, the optimal control of quadratic performance index is compared and analyzed against the traditional recommended PID optimal regulating. The results of simulation show that their dynamic processes are different obviously. The former presents noncycle fast steady feature, but the latter presents attenuation oscillation processes.

    Along with the perfection of virtualization technology, virtual environment of computer hardware can execute all commands of real computer. Virtual server achieves wide application in all fields for the purpose of investmentsaving and convenience of server management. But blackout is still the most familiar reason of virtual server’s damage. Even though equipped with a UPS, a virtual server would collapse without power strong enough supplied by the UPS. The system will be off if the power of UPS is not enough by monitoring the power at virtual server. The diagnostic services program polls the virtual server, and executes a command of poweroff without a reply, even then sends a message and email to the manager. It is an intelligent management of selfprotection at blackout and power on automatically after power resuming that the virtual server realizes.
