Self-Organizing Maps (SOM) is an excellent method of analyzing multidimensional data. The SOM based classification is attractive, due to its unsupervised learning and topology preserving properties. In this paper, the performance of the self-organizing methods is investigated in induction motor rotor fault detection and severity evaluation. The SOM is based on motor current signature analysis (...

The paper analyses how the characteristics of medium-voltage network with insulated neutral and conditions under which single line-to-ground fault occurs (insulation condition value resistance) influence zero-sequence components voltage transformer station bus bar, current, currents faulted line other non-faulted power lines connected to bars. Assuming waveform medium voltages in is known, resi...

Broken adaptive ridge (BAR) is a computationally scalable surrogate to $$L_0$$ -penalized regression, which involves iteratively performing reweighted $$L_2$$ penalized regressions and enjoys some appealing properties of both while avoiding their limitations. In this paper, we extend the BAR method semi-parametric accelerated failure time (AFT) model for right-censored survival data. Specifical...

Landslides are frequent in the Nanpeng River fault zone southwest Yunnan. Based on a Zhen Qing Expressway survey, geological conditions and characteristics of landslides this area were studied. The conclusions as follows: 1) background was internal cause local highly steep slopes broken rock masses. main landslide types study fault-type accumulation landslides. 2) formation is related to endoge...

[1] We argue that key features of thrust earthquake triggering, inhibition, and clustering can be explained by Coulomb stress changes, which we illustrate by a suite of representative models and by detailed examples. Whereas slip on surface-cutting thrust faults drops the stress in most of the adjacent crust, slip on blind thrust faults increases the stress on some nearby zones, particularly ab...

The current Air Force aircraft logistics system is reactive in nature, meaning that once a fault is detected, maintenance personnel must perform fault isolation procedures and then take steps to repair or replace the faulty item. The Autonomic Logistics System (ALS) concept changes this reactive process into a proactive one. This new approach to the logistics process shows the potential for cos...
