ROUNDNESS ERROR AND TOPOGRAPHY OF HARD TURNED SURFACES
Cutting & Tools in Technological System, 2023 Accuracy and topography are significant indicators of precision machined high-quality surfaces. Case hardened steel (16MnCr5) was analyzed to obtain information about the effects of technological data and the connections between the analyzed accuracy (roundness) and roughness parameters (Sa, Sz, Ssk, Sku).

‘Hard AI Crime’: The Deterrence Turn
Oxford Journal of Legal StudiesAbstract Machines powered by artificial intelligence (AI) are increasingly taking over tasks previously performed by humans alone. In accomplishing such tasks, they may intentionally commit ‘AI crimes’, ie engage in behaviour which would be considered a crime if it were accomplished by humans.
