The firefighter problem is defined as below. A fire initially breaks out at a vertex r on a graph G. In each step, a firefighter chooses to protect one vertex, which is not yet burnt. And the fire spreads out to its unprotected neighboring vertices afterwards. The objective of the problem is to choose a sequence of vertices to protect, in order to save maximum number of vertices from the fire. ...

Based on the predigestion of dynamic model intelligent firefighting vehicle, a linear 2-DOF lateral and preview error are established. To solve problems highly non-linear vehicle model, time-varying parameters, output chattering, poor robustness, Radial Basis Function neural network sliding mode controller is designed. Then, different driving speeds used to conduct simulation tests under standa...

Maritime safety is an ongoing process in shipping that constantly being improved by the modernization of equipment and constant improvements operators’ procedures training. However, human error remains a significant factor maritime accidents, as it contributes to 75% incidents. Addressing this problem, current paper shows proof principal for on-board fire monitoring extinguishing software agent...

Increased water scarcity implies that residents of arid, heavily populated regions of the U.S. will have to increase water conservation or else face the consequence of water shortfalls. Voluntarily conserved water is an impure public good since it is non-excludable and rival in consumption. This means that water conservation benefits are subject to free-riding behavior. This paper considers a d...
