Anomaly detection based on telemetry data can improve the operating safety for spacecrafts. Most of the anomaly detection methods in this domain are based on Euclidean distance for similarity measure of monitoring parameters. However, the Euclidean distance has many limitations on telemetry data similarity measure and may affect the detecting performance. Therefore, improved distance measures and...
Carbon nanorods (CNRs) have been attracting increasing interest because of their potential applications in high-performance nanoscale materials and electronic devices. Among the many preparation methods, the nanocasting method via inorganic template materials exhibited a controllable and facile feature. This work was to present a novel preparation of CNRs through the nanocasting method using halloysite...
Time and frequency synchronization is prerequisite of coordinating multi-static radar system. However, available synchronization methods do not provide practical beyond line-of-sight synchronization especially under the condition of maneuver. Therefore, a novel time and frequency synchronization mechanism based on troposcatter has been proposed. And the main motivations of this paper are to analyze...
The attributes of microwave dielectric ceramic have been studied from two aspects: working state and relative dielectric constant. Its four applications in microwave oven are elicited. Ceramics in resonant state can be used in microwave oven of fixed boundary condition; ceramics in detuned state are made into shimming panel; high permittivity ceramics are used to make flexible fast defroster and low...
