Detecting a Suddenly Arriving Dynamic Profile of Finite Duration

Quickest Detection of Intermittent Signals With Application to Vision Based Aircraft Detection

“…where detection procedures are reset after each false alarm [7]; quickest transient detection seeks to identify a change that occurs once for a period of time and then disappears [8], [9]; and quickest detection under transient dynamics that seeks to identify a persistent change which does not happen instantaneously, but after a series of transient phases [10]. In this paper, we consider a new quickest ISD problem where a change can repeatedly appear and disappear over time.…”

Sequential detection of a total instantaneous blockage occurred in a single subassembly of a sodium-cooled fast reactor

“…A change detected with the delay greater than N , i.e. T − t 0 + 1 > N , is assumed to be missed [30,31,32,33]. On the other hand, if the true duration Γ of the transient change is smaller, than the required time-to-alert N , such a transient change is considered as less dangerous because its impact on the system is limited or negligible.…”

“…The design of the transient change detector is discussed in [31,32,33]. Let us briefly define this FMA test, which has been obtained as a result of optimisation in a subclass of truncated SPRT.…”

“…To get upper bounds for the probabilities P md (T FMA ) and P fa (T FMA ; m α ) defined in criterion ( 19) - (20), it is necessary to respect some technical conditions and define several probabilities and their bounds. Further details and results can be found in [32,33]. The worst-case probability of missed detection P md (T FMA ) is upper bounded as follows [33]…”
