I N T R O D U C T I O N A N D P R O B L E M M O T I V A T I O N Old Faithful, the most famous geyser in Yellowstone National Park, is known for the regularity and predictability of its eruptions. Predictability, however, has many gradations. Although it is possible to predict an eruption after observing the previo...

Using neural networks to predict road roughness

When a vehicle travels on a road, different parts of vehicle vibrate because of road roughness. This paper proposes a method to predict road roughness based on vertical acceleration using neural networks. To this end, first, the suspension system and road roughness are expressed mathematically. Then, the suspension system model will identified using neural networks. The results of this step sho...

Mechanics of Old Faithful Geyser, Calistoga, California

[1] In order to probe the subsurface dynamics associated with geyser eruptions, we measured ground deformation at Old Faithful Geyser of Calistoga, CA. We present a physical model in which recharge during the period preceding an eruption is driven by pressure differences relative to the aquifer supplying the geyser. The model predicts that pressure and ground deformation are characterized by an...
