The Ore Mountains in the Czech-German borderland (Central Europe) were depopulated after the 2nd World War. The rapid population decrease affected the industry that used to be in this region for ages and almost all the industry in the Czech side of the Ore Mountains vanished. More than 240 vanished objects (factories, technical objects, manufactures) were identified during background research and the field survey in the area of interest. Based on the history and depopulation of this region, the vanished objects ma...

Recent online translators for languages without a significant number of speakers cannot reach the quality of the translators for languages such as English, Spanish, and French, etc. The great number of users of these common languages means a higher possibility of correction of an inaccurate translation. For those languages with around ten, twenty million speakers, translators cannot gain such effectivity. All the documents produced in the EU must be translated into all the languages of the EU. Translators that hav...

Backward-compatible software allows to change its libraries without rebuilding and adapting the interface used for interaction between its components or other applications (application programming interface, API). Application binary interface (ABI) compatibility is important for application portability. There are ready-made solutions to verify binary compatibility, such as libabigail and ABI-compliance tools. Such tools have several disadvantages. For example, libabigail works only with libraries containing DWARF ...

The significant centres of settlement on the territory of the Czech Republic have also their suburbs aside from their core areas (centres). The dynamics of outflow of population from city centres to suburban areas influences significantly the global character of a city as such. The influence of suburbanization is currently evident in all larger residential centres. The urbanization of rural population and the extension of administration boundaries of cities lead to distinguished and mutual interaction of the neigh...
