Research on compressive sensing of strong earthquake signals for earthquake early warning
Geomatics, Natural Hazards & Risk, 2021 Earthquake early warning is an effective method to reduce casualties and losses. Based on the theory of compressive sensing, this paper proposes a strong earthquake signal processing architecture based on compressive sensing for difficulties of the ...

Avoidance of a warning signal [PDF]
Psychonomic Science, 1968 Rats were scheduled to receive electric shock every 20 sec, half under the typical nondiscriminated procedure where shock is scheduled from the last response, and half under a fixed-cycle procedure where shock is scheduled regularly by time. For half of each of these groups, a 4 sec CS preceded the shock.

Machine classification of code signals in electric train warning systems [PDF]
Омский научный вестник, 2019 Automatic train warning systems beeing currently in service on Russian railways use electric track circuits as signal communication media. Electric signals transmitted through a track circuit often get corrupted by the noise produced by electric ...

Probabilistic Multivariate Early Warning Signals
, 2022 A broad range of natural and social systems from human microbiome to financial markets can go through critical transitions, where the system suddenly collapses to another stable configuration. Critical transitions can be unexpected, with potentially catastrophic consequences.
