Improving the calculation of the cost of the construction project using BIM technology

In the scientific article the authors summarize the results of theoretical research and practical implementation in the design of residential and public buildings BIM - information modeling technology. The questions of application of digital models for control of financial expenses at all stages of project implementation in construction are considered. An attempt is made to harmonize BIM technology with the Comsol Multiphysics software package. A review of existing studies on this issue in Europe, Asia, the United States and Russia. With the participation of the authors of the article developed a set of specialized families for the system Autodesk Revit, which allow you to perform a comprehensive preliminary study of the construction site of residential buildings. The approach providing increase of efficiency of determination of estimated cost of works on construction of object of construction based on several generalized principles is offered. This innovative approach has been tested in the design of several large construction projects in the Ural region of Russia, implemented in 2017-2019. © Published under licence by IOP Publishing Ltd

Evidence of phi --> pi0 pi0 gamma and phi --> pi0 eta gamma decays in SND experiment at VEPP-2M

Preliminary results on the study of e+e- --> phi(1020) --> pi0 pi0 gamma, eta pi0 gamma processes from SND experiment at VEPP-2M collider in Novosibirsk are presented. Branching ratios of rare radiative phi --> pi0 pi0 gamma and phi --> pi0 eta gamma decays are measured: B(phi --> pi0 pi0 gamma ) = (1.1 +- 0.2) * 10^-4 (invariant mass (pi0 pi0) < 800 MeV), B(phi --> eta pi0 gamma ) = (1.3 +- 0.5) * 10^-4.Comment: Talk at the HADRON97 conference, BNL, Aug 24-30 1997; LaTeX, 4 pages, 4 eps figure

Review of experimental results from SND detector

The review of experimental results obtained with SND detector at VEPP-2M $e^+e^-$ collider in the energy region $\sqrt[]{s}=0.36$ -- 1.38 GeV is given. The presented results include the following items: studies of the light vector mesons radiative decays, OZI-rule and G-parity suppressed $\phi$-meson rare decays, $\phi$-meson parameters measurements, studies of $e^+e^-\to\pi^+\pi^-\pi^0$ process dynamics, $\eta$ and $K_S$ mesons rare decays, $\eta$ and $\phi$ mesons conversion decays, and study of the $e^+e^-$ annihilation into hadrons.Comment: 12 pages and 6 figures. Talk given at the IX International Conference on Hadron Spectroskopy, Protvino, Russia, August 25 - September 1, 200
