Equipment failures are becoming one of the major threats in the chemical process industry. The marriage of WSN and large scale of monitoring data bring the new challenges. To address these issues, in this paper, we propose surveillance methods that can monitor the running condition of chemical equipments. Our methods are based on skyline operator and quickly identify such equipment in potential danger...
We investigate the emergence of chaotic behavior in the form of strange attractors with SRB measures when certain Héenon maps are kicked at periodic time. The setting considered is periodic solution obtained from unperturbed system. Through numerical simulations, rank one chaos are observed for many large kicking periods.
The attribute core of inconsistent decision table plays an important role in rough set theory (RST). However, the existing methods are difficult to distinguish between the consistent core and inconsistent core attributes. In this paper, we present a novel calculation for core attributes of inconsistent decision table by proposing two improved discernibility matrices which correctly obtain core attributes...
This paper is concerned with chaotification of a stable linear time-invariant (LTI) system in finite-dimensional real spaces. By using feedback controller of wavelet function, the controlled system is proved to be chaotic in the sense of Devaney. The advantage of using wavelet to control stable system is that much of the control energy can be saved and the control expense is economical. So it is convenient...
