Uncertainty associated with model predictions of surface and crown fire rates of spread
The degree of accuracy in model predictions of rate of spread in wildland fires is dependent on the model’s applicability to a given situation, the validity of the model’s relationships, and the reliability of the model input data. On the basis of a compilation of 49 fire spread model evaluation datasets involving 1278 observations in seven different fuel type groups, the limits on the predicta...
متن کاملSweeping dishonesty under the rug: how unethical actions lead to forgetting of moral rules.
Dishonest behavior can have various psychological outcomes. We examine whether one consequence could be the forgetting of moral rules. In 4 experiments, participants were given the opportunity to behave dishonestly, and thus earn undeserved money, by over-reporting their performance on an ability-based task. Before the task, they were exposed to moral rules (i.e., an honor code). Those who chea...
متن کاملParallel Performance of a New Model for Wildland Fire Spread Predictions
A new approach to simulation of wildland fire spread is outlined, and preliminary results of computations and parallelization of the algorithms are presented and discussed. The fire spread model is based on a porous medium representation of the forest with heat source terms replacing treatment of detailed chemistry. The formulation is implemented in conjunction with a synthetic-velocity form of...
متن کاملRelieving the Effects of Uncertainty in Forest Fire Spread Prediction by Hybrid MPI-OpenMP Parallel Strategies
The accurate prediction of forest fire propagation is a crucial issue to minimize its effects. Several models have been developed to determine the forest fire propagation. Simulators implementing such models require diverse input parameters to deliver predictions about fire propagation. However, the data describing the actual scenario where the fire is taking place are usually subject to high l...
متن کاملEvaluating Crown Fire Rate of Spread Predictions from Physics-Based Models
Modeling the behavior of crown fires is challenging due to the complex set of coupled processes that drive the characteristics of a spreading wildfire and the large range of spatial and temporal scales over which these processes occur. Detailed physics-based modeling approaches such as FIRETEC and the Wildland Urban Interface Fire Dynamics Simulator (WFDS) simulate fire behavior using computati...
