Abstract A duplex treatment consisting of plasma nitriding (PN) and physical vapor deposition (PVD) significantly improves the thermal, tribological, and corrosion resistance of forming tools, and especially if they are intended for applications subj

Autor: Vjaceslav Sochora, Vladimír Karas, Jirí Svoboda, Michal Dovciak

Publikováno v: Acta Polytechnica, Vol 54, Iss 4, Pp 300-304 (2014)

The strong gravitational field of a black hole has distinct effects on the observed profile of a spectral line from an accretion disc near a black hole. The observed profile of the spectral line is broadened and skewed by a fast orbital motion and re

Extremal energy shifts of radiation from a ring near a rotating black hole

Autor: Vjaceslav Sochora, Vladimir Karas

Radiation from a narrow circular ring shows a characteristic double-horn profile dominated by photons having energy around the maximum or minimum of the allowed range, i.e. near the extremal values of the energy shift. The energy span of a spectral l
