Empirical comparison of bagging-based ensemble classifiers by Suganthan, P. N., Ye, Ren

“…The comparison of these four ensemble classifiers is novel because it has not been reported in the existing literature. The classifiers are evaluated with thirteen binary class datasets and the empirical results show that the ensemble methods employed in the four ensemble classifiers boost the testing accuracy by 1-5% on average from their base classifiers. …”

Factors affecting pre-failure instability of sand under plane-strain conditions by Wanatowski, D., Chu, Jian

“…However, this type of instability is different from the runaway type of instability observed under undrained conditions, and has therefore been called conditional instability. Despite the differences, the conditions for both types of instability are the same for contractive sand. …”
