This paper describes a novel approach to sensor and actuator integrity monitoring. Multiple sensor and actuator faults can be detected and isolated. Most importantly, fault magnitudes can be correctly estimated. Our approach is robust to disturbance and does not require additional sensors.
Envelope analysis has been widely used in health monitoring and fault diagnosis of rolling element bearings. However, the manual frequency band selection limits its accuracy in extracting transient features from a noisy signal and identifying defects, especially for detecting an incipient defect of the bearing. Because the complex Morlet wavelets have the similar time-frequency structure with the...
Anomaly detection of executable program is a security detection solution that examines whether security violation issues exist in programs. The paper presents a novel anomaly detection approach for executable program security (ADEPS), which monitors program executions and detects anomalous program behaviors. Through reverse analysis of executable program, critical behavior monitoring points can be...
Analysing the need of developing petition processing system's internal cooperation of letter processing among departments, external cooperation of mutual exchange between government and urban people, and automatic cooperation of information integration with heterogeneous systems, the authors put forward a cooperative petition processing model and based on this model realize cooperative petition processing...
