Neural network prediction of web-crushing strength of i-shaped reinforced concrete beams

Autor: Murat M. Tamov, Olga V. Rudenko, Sergey V. Usanov

Publikováno v: Vestnik MGSU. :1145-1159

Introduction. Under the combined action of shear force and bending moment web-shear cracking takes place in the thin webs of reinforced concrete beams. The strength of the concrete struts between the cracks depends on the size of the web, concrete st

Light-activated photoluminescence of porous silicon

Autor: Mykola S. Boltovec, Svitlana Naumenko, Olga V. Rudenko, Oleksandr I. Dacenko, Tetjana V. Ostapchuk

Publikováno v: SPIE Proceedings.

Samples ofporous silicon (PS) were etched in concentrated hydrofluonc acid. The initial and etched samples were exposed tothe air by pairs at room temperature either in the dark or in daylight. In the process of exposition the integrated intensity of

Structure and optical parameters of the system with porous silicon: ellipsometric study

Autor: Mykola S. Boltovec, Volodymyr A. Odarych, Olga V. Rudenko, Volodymyr O. Pasichnyj, Oleksandr I. Dacenko

Publikováno v: SPIE Proceedings.

The principal angle-of-incidence (Phi) and ellipticity tg(rho) of the light reflected from PS surface are measured in the visible on two samples by spectroellipsometry methods. The dependence of the reflected light intensity in the s-plane and ellips

Journal de Physique IV Proceedings, EDP Sciences, 1994, 04 (C4), pp.C4-163-C4-166. ⟨10.1051/jp4:1994436⟩

There was investigated the change of Y-Ba-Cu-O structure of monocrystallic films and polycrystallic facings under the effect of laser radiation (1,06 μm, 4 ms). The obtained results indicate the threshold character of changes of their superconductiv
