Information system evaluation is of increasing importance in current society. Based on multidimensional utility combined methods, this paper establishes a flexible and accurate evaluation system which applies to various kinds of information system evaluation. Firstly established a complete objective index system, then used multidimensional utility model to create a new evaluation model. According to the specific circumstances, this model set merger rules and weights. It is multi-angle, intensive and flexible. At last, the effectiveness, accuracy and flexibility of the method has been well demonstrated by experiment and comparison. Source

This article compares the new ambient quality standards adopted by China on 29 February 2012 with the previous ambient air quality standards and reveals the significance of and reasons for this revision. It points out that the new ambient air quality standards added fine particulate matters into the items to be monitored, reclassified monitored items into the group of basic items to be mandatorily monitored nationwide and the group of other pollutants to be monitored discretionally, and set the maximum concentration for each of the two categories of areas. This revision was in response to the demand of the general public for less pollution and better information on the air quality. This revision is important for the human health because it imposes a new task on local governments. The new standard shall be implemented gradually, beginning with most seriously polluted areas, and finally to be implemented nation-wide. This revision is expected to contribute to better protection of human health. © (2013) Trans Tech Publications, Switzerland. Source

After years of rapid economic development, environmental pollution has become a big concern to the general public in China. Numerous mass protests happened because of actual or perceived environmental pollution. This article makes a case study of three recent mass protests to find the features and deeper causes of mass protests for environmental issues. It concludes that, without sufficient information disclosure, the general public may still protest and the government may yeild, even if a project followed all governmental procedures and obtained all governmental approvals. This harms both the credibility of the government and the economy, and eventually the interests of the public. Chinese government has found the deeper causes and is working on the right direction. © (2013) Trans Tech Publications, Switzerland. Source

With the rapid development of intelligent buildings, a lot of researchers have found that it is difficult to establish mathematical model when the problem that energy-saving in water supply system of an intelligent building tank is focused, because that the outflow of the tank volume is volatile when the water is daily living water. In this paper, fuzzy control theory is used to establish a fluid level, and the fluid input flow rate to determine the amount of control, which to push the valve's opening size and speed in order to control the water supply valve opening adjustment level, so that the liquid position of container maintains a constant, and the MATLAB software is used to verify the effect of fuzzy control system. The results show that in this fuzzy control system the benefits of economic operation of water supply can be ensured by ensuring a constant level of liquid. ©2011 ACADEMY PUBLISHER. Source

Heterogeneous data produced by Internet of Things increased continually. Inconsistent semantics of data became obstacle of sharing data. To handle them effectively and intelligently, a semantic model for Internet of Things was proposed, which was based on semantic technology and cloud computing. Scalable distributed file system was the basis of storing mass data. Distributed inference engine, which was based on Map/Reduce operation model, had solved the problem of reasoning on mass ontology. Hierarchical semantic provided the basis of intelligent processing, which had reached consistent understanding between heterogeneous data. Global ontology laid emphasis on solving interoperation, local ontologies laid emphasis on personalized knowledge. Source
