This paper was to appraise susceptivity of soil erosion and identify its spatial distribution in Three Gorges region in Chongqing, Southwest China based on geographic information system (GIS). The data of rainfall erosivity, soil erodibility, topographic undulation and land use/land cover were used to appraise susceptivity with synthetical index model of soil erosion susceptivity and analyze its spatial distribution with ArcGIS9 software. The results showed that the susceptivity of soil erosion was severe in the mass and its spatial difference was obvious due to integrative effect of the rainstorms, soil erodibility, topography, and land use/land cover in Three Gorges region. The main susceptivity classes of soil erosion are marginally sensitive, moderately sensitive and highly sensitive levels and their areas are 18, 61 and 21 percent respectively in the study area. Those areas with high susceptivity distribute in mountains in northeast and southeast of Chongqing due to thin soil, steeper terrain, poor management, and sparse vegetation. High priority should be given for those highly sensitive areas to conserve soil resources by identifying susceptivity of soil erosion, planning and promoting land use/land cover, and optimizing management for maintaining and improving soil productivity and sustainable development of eco-environment in Three Gorges region.

In the last few years, rules are increasingly being used for knowledge representation in ontology-based business rule systems on the Semantic Web. As the size of rule bases increases and there exist a great number of rules engines with its own rules language, users face the problem in understanding and managing the complexity of the knowledge represented by the rules. To address this problem, we have implemented a visual semantic rule management tool called JRE (Java Rule Editor). The main goals of this tool are: first, to help non-specialists to understand and edit the meaning of complex rules with rule visualization and, second, to make this development independent of rule engine products. Rules do not include its own rule engine implementations but acts as a broker to the preferred rule engine. In this way, business rules can be reused across different rule engines and through different projects in the company. The JRE is part of a project devoted to the definition of a new platform core for semantic logistics system.

Receiver Autonomous Integrity Monitoring (RAIM) for Global Positioning System (GPS) is required for safety and liability critical applications such as aircraft nonprecision approach, river and harbour navigation real-time or kinematic surveying, etc. It is important to monitor the accuracy and precision of the navigation solution. While existing RAIM techniques, many algorithms require a high computational capacity. In this paper, a scheme for fault detect, which uses the pseudorange residual message, is presented.

The value of decision variables is compared to the thresholds that have been set to satisfy the integrity requirements, to decide whether or not the corresponding navigation measurement will have a fault solution. The validation and analysis based on the real GPS data show that the scheme facilitates real-time integrity monitoring of the accuracy of the navigation solution of GPS receiver. Meanwhile, the method is much more simple, convenient and practical for GPS receiver which includes the pseudorange residual message.

Ubiquitous questionnaire is to provide users with E-questionnaire services anytime and anywhere such that one can use E-questionnaire servers without even thinking about them. A general-purpose E-questionnaire server for ubiquitous questionnaire, named “ENQUETE-BAISE”, was proposed. It deals with not only E-questionnaire, but also E-voting and E-testing. On the other hand, the most intrinsic feature of ubiquitous questionnaire is to allow anyone to execute any kind of questionnaires anytime anywhere such that any respondent can answer questionnaires anytime anywhere. ENQUETE- BAISE should provide an environment that any user can do E-questionnaire, E-voting, or E-testing in his/her well-used locale. However, current ENQUETE-BAISE cannot provide such an environment. This paper proposes a mechanism to deal with internationalization of E-questionnaire, E-voting, and E-testing, and shows internationalization of ENQUETE- BAISE. The proposed mechanism is not ad-hoc such that it is independent of functional requirements of E-questionnaire, E-voting, and E-testing. Thus, we can use the mechanism continuously if ENQUETE-BAISE becomes more complex or more functional.

In current information society, one can get huge amount of data easily and quickly. However, it is not so easy to extract useful information from huge amount of data. Undergraduate students and graduate students are not skillful with extracting useful information from huge date they got. They need a service to support their studying in a comprehensive way. Therefore, a service to help undergraduate students and graduate students should help their studying and extracting useful information from huge data they got. This paper proposes an evolutionary personal information partner for students studying in universities that can store and manage all its user’s information related studying, and autonomously provide the user with advices about studying. Undergraduate students and graduate students can spend useful days in their life because the service the evolutionary personal information partner for studying in universities provides.
