According to the definition of simple random sampling for the attribute data in GIS, the mean and variance of the RD are deduced as the characteristic value of the statistical model in order to explain the feasibility of the accuracy measurement of the attribute data in GIS by using the RD. Moreover, on the basis of the mean and variance of the RD, the quality assessment method for attribute data of vector maps during the data collecting is discussed. The RD spread graph is also drawn to see whether the quality of the attribute data is under control. The RD model can synthetically judge the quality of attribute data, which is different from other measurement coefficients that only discuss accuracy of classification.展开更多

The alignment of data mining and business would bring benefits to the organization＇s management. The study investigated the adoption of data mining technologies in managerial accounting system, concentrating on the challenges and opportunities. The research showed that with the technology adoption, managerial functions could be improved and current information system could be upgraded. Since the technical progresses are reshaping the world of business and accountancy, it is significant for accountants and finance professionals to exploit information technologies.展开更多

Current digital forensic approaches mainly focus on memory and I/O data, while the runtime instructions from processes are often ignored. We present a novel approach on runtime instruction forensic analysis and have developed a forensic system which collects instruction flow and extracts digital evidence. The system is based on whole-system emulation technique and analysts are allowed to define analysis strategy to improve analysis efficiency and reduce overhead. This forensic approach and system are applicable to binary code analysis, information retrieval and matware forensics.展开更多

The method comes with less or no side effects, comparing the western medicine chemicals. With the new computer information technologies, the ancient Chinese healing tool could be very convenient for people to take care of themselves at home or work. In this paper, the authors present their online database system for locating the acupressure points. A case study shows the details of the design and structure of the online system.展开更多

According to the national physical education and health course standards and the fundamental theories of the constructivisrn, the author adopts the modular-design development method to design two functional areas which are the displaying of the teaching design contents and the online information database （nine modules in total） on the basis of the P.E. teaching design flow. Importantly, this system features the compatibility, scalability and practical applicability, and can effectively improve the ability of P.E. teachers to design their teaching, and hence provides a guarantee for the improvement of teaching quality and efficiency.展开更多
