Luminous Phenomena of Earthquakes: Observations and Theories
Over the past few years, different theories (piezoelectric, positive holes, friction-vaporization, exo-electron emission, tribo- or fracture electrification) have been presented for the interpretation of earthquake lights. Although these theories can interpret earthquake luminous, each suffer from particular problems. There are also ambiguities and questions about the location of the light, the...
متن کاملTraining Crisis Managers with PANDORA
This short paper introduces a novel use of timeline-based planning as the core element of a dynamic training environment for crisis managers called PANDORA. A trainer is provided with a combination of planning and execution functions that allow him/her to maintain and adapt a “lesson plan” as the basis for the interaction between the trainer and a class of trainees. The training session is base...
متن کاملThe Pandora Effect
Curiosity—the desire for information—underlies many human activities, from reading celebrity gossip to developing nuclear science. Curiosity is well recognized as a human blessing. Is it also a human curse? Tales about such things as Pandora’s box suggest that it is, but scientific evidence is lacking. In four controlled experiments, we demonstrated that curiosity could lead humans to expose th...
متن کاملPandora: the Time of Priority-and Gates
Classical Fault Tree Analysis (FTA) can determine the effects of combinations of failure events on a system but cannot capture the potentially critical significance of the temporal ordering of events. In this paper, we propose a temporal extension based on the use of Priority-AND gates to allow relative temporal ordering and temporal analysis in FTA. The classical notion of minimal cut-sets is ...
متن کاملUnderstanding the Behavior of Prometheus and Pandora
We revisit the dynamics of Prometheus and Pandora, two small moons flanking Saturn’s F ring. Departures of their orbits from freely precessing ellipses result from mutual interactions via their 121:118 mean motion resonance. Motions are chaotic because the resonance is split into four overlapping components. Orbital longitudes were observed to drift away from predictions based on Voyager epheme...
