As a geological process that wears away soil, rock, or dissolved material, erosion may result in the loss of soil layers are rich nutrients for plant growth and reducing ability to absorb store water. High rainfall causes high level erosivity which can lead increase intensity. Therefore, predicting erosion, rain condition needs be considered most, especially tropics. This study was conducted Sa...

Next Generation Air Traac Management will allow for the possibility of free ight, in which each aircraft chooses its own optimal route, altitude and speed. In a free ight environment, the trajectories of several aircraft may be connicting, in which case aircraft may or may not cooperate in resolving the connict. This paper presents a method for noncooperative connict resolution in which each ai...
