(e.g. earthquake, vibration or blast) loadings, leading to phenomena of liquefaction. The pore water in a saturated sandy soil will increase due to the tendency of the volume contraction if the drainage of the water is impeded. This results in a lower effective stress and, consequently, the reduction of soil strength.

Assessment of advanced random forest and decision tree

Landslides represent a part of the cascade of geological hazards in a wide range of geo-environments. In this study, we aim to investigate and compare the performance of two state-of-the-art machine learning models, i.e., decision tree (DT) and random forest (RF) approaches to model the massive rainfall-triggered landslide occurrences in the Izu-Oshima Volcanic Island, Japan at a regional scale.

Atlas D - Encyclopedia Astronautica

The first Atlas D model flight test missile (3D) had to be destroyed 36 seconds into flight due to a severe engine malfunction and explosions. In addition to other changes, the D series replaced the MA-1 engine package with the Rocketdyne MA-2. The booster engines in the MA-2 produced 309,000 pounds of thrust versus 300,000 pounds for the MA-1.
