Introduction This paper describes ongoing efforts to extend our work (Geib & Goldman 2001b; 2001a) (G&G) on the Probabilistic Hostile Agent Task Tracker (PHATT) to handle the problem of goal abandonment. As such, we will be discussing both probabilistic intent inference and the PHATT system and assume the reader is familiar with these areas. We refer the interested reader to the complete paper ...

The influence of the ventilation system on the abandoned gob weakens, so the gas seepage characteristics in the abandoned gob are significantly different from those in a normal mining gob. In connection with this, this study physically simulated the movement of overlying rock strata. A spatial distribution function for gob permeability was derived. A numerical model using FLUENT for abandoned g...

Although soil invertebrates play a decisive role in maintaining ecosystem functioning, little is known about their structural composition in Alpine soils and how their abundances are affected by the currently ongoing land-use changes. In this study, we re-assessed the soil macrofauna community structure of managed and abandoned Alpine pastureland, which has already been evaluated 14 years earli...

BACKGROUND Until recently, a lot of arable lands were abandoned in many countries of the world and, especially, in Russia, where about half a million square kilometers of arable lands were abandoned in 1961-2007. The soils at these fallows undergo a process of natural restoration (or self-restoration) that changes the balance of soil organic matter (SOM) supply and mineralization. RESULTS A s...
