The identification of temperature filed of monitored region is one of the key steps for the energy efficiency management in intelligent building. In this paper, the identification of temperature field is treated as one optimization problem and the identification structure for that optimization problem is implemented with a RBF neural network. To increase the accuracy of RBF based temperature field identification model, normalization methods based on stereographic projection for raw monitored data are discussed in this paper too. To test the performance of our proposed normalization methods, temperature matrix for the infrared photograph is used in our experiment Experiment results show that the performance of RBF based temperature field identification model running with data preprocessed by stereographic projection and minimum-maximum method for the identification of temperature field in monitored region is best.

With the shortage of natural resource and deterioration of environment, the environment sound technology innovation (ESTI) has become the necessary way for enterprises to develop sustainably. However, China's enterprises have a lot of problems in the practice of ESTI. Firstly, the paper analyzed the influence factor of ESTI, such as capital, technology, marketing and so on;secondly, the paper explained the effect of ESTI on the sustainable development strategy;finally, the paper put forward some countermeasures for promoting ESTI of enterprise.

For the sustainable development of oceans, we need a reliable, effective and fast MEIA (Marine Environmental Impact Assessment) System. According to the certain goal of MEIA system, this paper design a preliminary MEIA System based on 3S technology. The system consists of a database management subsystem, statistical analysis subsystem and MEIA subsystem. It will put the 3S technology to the best use to achieve the analysis, evaluation, decision automation, technology process and visualization of MEIA. Taking into account the scalability of the system, it will reserve the interface for secondary development. (C) 2011 Published by Elsevier Ltd.

How to retrieve and query large XML documents efficiently has become a challenge in the database field for several years. A few efforts have been made in the past to address this *** this paper, we present a novel approach using pagination technique and index structure in a native XML database system named CanStoreX. The system is able to handle very large XML documents efficiently using only a small amount of memory space. The experimental results have shown that the index structure proposed in this paper could dramatically improve the performance of the XQuery engine on a pagination based native XML storage.

This paper studies the software scenario testing, which is commonly used in black-box testing. In the paper, the workflow model based on task-driven, which is very common in scenario testing, is analyzed. According to test business model in scenario testing, the model is designed to corresponding test case suite. The test case suite that conforms to the scenario test can be obtained through test case generation and test item design. In the last part of the paper, framework of test case suite design is given to illustrate the effectiveness of the method.
