This paper reviews current developments in mechatronic systems for metal cutting and forming machine tools. The integration of mechatronic modules to the machine tool and their interaction with manufacturing processes are presented. Sample mechatronic components for precision positioning and compensation of static, dynamic and thermal errors are presented as examples. The effect of modular inte...

In this paper, the problem of constructing geometric models from data provided by 3-D imaging sensors is addressed. Such techniques allow for rapid model-ing of sculptured free-form shapes and generation of geometric models for existing parts. In order for a complete data set to be obtained, multiple images, each from a diierent viewpoint, have to be merged. A technique stemming from the Iterat...

The Prague Dependency Treebank (PDT, as described, e.g., in (Hajič, 1998) or more recently in (Hajič, Pajas and Vidová Hladká, 2001)) is a project of linguistic annotation of approx. 1.5 million word corpus of naturally occurring written Czech on three levels (“layers”) of complexity and depth: morphological, analytical, and tectogrammatical. The aim of the project is to have a reference corpus...
