Livestock grazing and fire suppression effects, for example, have arguably had minimal effects on changes in vegetation and fuel dynamics in many shrublands (e.g., southern California chaparral) or in higher elevation spruce-fir forests.
Understanding fuel dynamics over large spatial (103 106 ha) and temporal scales (101 103 years) is important in comprehensive wildfire management.
The analytical model considers homogeneous two-phase flow, a point kinetics model for the neutron dynamics and a lumped heat transfer model for the fuel dynamics.
Two-zone lumped parameter model is developed encompassing the thermalhydraulic, fuel dynamics and power dynamics equations, which are subsequently employed for linear stability analysis and also for transient simulations.
Evidence from Australian Eucalyptus forests suggests that mitigation of risk using prescribed burning as a fuel treatment is partial because weather and fuel dynamics are conducive to regular high intensity fires.
The optimization of fuel hazard management is nevertheless curtailed by the current state of knowledge about crown fire behaviour and fuel dynamics in relation to stand development and silviculture.
Interactions between the carbon cycle and fire behavior models are included, such that the carbon model simulates fuel dynamics and post-fire vegetation growth and the fire model simulates biomass burning (carbon dioxide emission, detritus production, and charcoal formation).
Therefore, the present study is carried out to draw a consistent picture on the commonly used and preferred biomass fuels, the dynamics of biomass fuel collection and the response of rural households to tree planting as a precaution of a future biomass fuel supply.
Both nominal and robust controller designs are verified through time response simulation for both nominal PEM fuel cell and nonlinear PEM fuel cell dynamics.
The present article analyses the effects of dilute biogas on efficiency, fuel utilisation, dynamics, control strategy, and design criteria for a polymer electrolyte fuel cell (PEFC) system.
