The delayed delivery of the AIRBUS A380© demonstrates the challenges to be faced in the field of cross-company collaboration today. On the one hand, available CWE platforms are used insufficiently. On the other hand, they do not yet support collaboration in a completely adequate way. This paper illustrates the current state of CWE practice by way of a sample company, its internal and external c...

Estimation of the height of caved and fractured zones above a longwall panel along with the stability conditions of the goaf area are very crucial to determine the abutment stresses, ground subsidence, and face support as well as designing the surrounding gates and intervening pillars. In this work, the height of caving-fracturing zone above the mined panel is considered as the height of destre...

Multiword expressions (MWEs) are linguistic objects containing two or more words and showing idiosyncratic behavior at different levels. Treebanks with annotated MWEs enable studies of such properties, as well as training and evaluation of MWE-aware parsers. However, few treebanks contain full-fledged MWE annotations. We show how this gap can be bridged in Polish by projecting 3 MWE resources o...

In this paper, the capability of determining three dimensional (3D) ground displacements due to underground mining using multiple ALOS PALSAR interferometric pairs acquired with different viewing geometry has been demonstrated in the area of West Cliff colliery, for longwall 32. 3D displacement maps have been derived from four interferometric pairs acquired from two different incidence angles e...
