A semi-automatic syntactic annotation of a part of the Czech National Corpus in the Prague Dependency Treebank (PDT) has among its aims the possibility to check the theoretical approach chosen (Functional Generative Description, see [2]). While the first phases of the annotation of PDT, i.e. the morphemic representations and the dependency trees on an intermediate analytic level, i.e. analytic ...

Approaches to detect energy efficiency measures are associated with time consuming analysis requiring expertise. Against this background, paper presents an expert system identify potentials for improving the of metal cutting machine tools based on measurement and meta data 35 machines. For purpose, it is necessary determine states control strategies their support units. Therefore, unsupervised ...

Small holes are drilled in diamond anvil cell gaskets to contain and pressurize samples. As high-pressure technology pushes the multimegabar regime, smaller-tipped diamond anvils are being increasingly utilized. Consequently, well-centered holes with diameters smaller than 100 pm need to be routinely produced in these gaskets made of exceedingly hard metals. We describe the construction of an i...

This paper is concerned with optimization of surface roughness when drilling of stainless steel SS304 with HSS drill. This study included drilling of SS304 with supply of Sic abrasive having grain size 650 and 1250 mesh size through abrasive slurry system. Abrasives not only used for cooling purpose but also increases the surface finish, MRR and reduce tool wear. Experiments were conducted on a...

Compressed-air tools are of interest by reason of their vibratory action which affects the peripheral circulation of the fingers. Raynaud's syndrome in riveters, pneumatic chisellers and drillers is well known. The harmful effect is almost certainly due to vibration, although cooling of the hands may occur with some pneumatic tools and may be a contributory factor.* Apart from using compressed ...
