The information about which modules in a software system's future version are potentially defective is a valuable aid for quality managers and testers. Defect prediction promises to indicate these defect-prone modules. Constructing effective defect prediction models in an industrial setting involves the decision from what data source the defect predictors should be derived. In this paper we compare...
The database correlation method (DCM) is a network based positioning technology which has shown superior in terms of accuracy. DCM is based on a pre-measured database of a location dependent variable such as received signal strength (RSS). Even though the technique has good potential, the practical difficulty in forming the database (fingerprints) using field measurements has become the major challenge...
Real-time databases are widely applied in time-critical applications, such as autopilot systems, robot navigation, real-time monitoring, programmed stock trading, etc. These applications usually require real-time databases can provide 7times24times60times60s' ceaseless service weekly. However, real-time databases cannot completely avoid all kinds of failures. The traditional recovery-processing scheme...
