FIRE, FUEL COMPOSITION AND RESILIENCE THRESHOLD IN SUBALPINE ECOSYSTEM.

BACKGROUND: Forecasting the effects of global changes on high altitude ecosystems requires an understanding of the long-term relationships between biota and forcing factors to identify resilience thresholds.Fire is a crucial forcing factor: both fuel build-up from land-abandonment in European mountains, and more droughts linked to global warming ar

Siphon computation is a basic step for developing siphon-based deadlock control approaches in a Petri net (PN) system.This work studies the enumeration of minimal siphons in a PN.Due to the fact that the number of siphons in a PN theoretically grows exponentially with the net size, the siphon enumeration is basically quadruple ointment for dogs tim
