Optimization of satellite resource scheduling under regional target coverage conditions
This study presented a mathematical description of an arbitrary shape area, and after analyzing the characteristics of the near-polar orbital co-ground trajectory constellation that satisfies the revisit interval constraint, an optimization model of the ...

Diagnosis of Intermittent Faults [PDF]
Discrete event systems (DESs) are considered for which faulty behaviour occurs ``intermittently'', with fault events \(f_i\), \(i=1,\dots,m\), followed by reset events \(r_i\), \(i=1,\dots,m\), followed by new occurrences of fault events, and so forth.
