Simulation of an incomplete algebraic problem of eigenvalues and vectors by the method of frequency-dynamic condensation based on FEM in the form of the classical mixed method
Autor: Alexander V Ignatyev, Artem V Chumakov, Vadim V Gilka
Publikováno v: Structural Mechanics of Engineering Constructions and Buildings, Vol 15, Iss 1, Pp 62-68 (2019)
Relevance . Dynamic analysis of complex structures using numerical methods leads to the solution of the algebraic problem of eigenvalues and the corresponding eigenvectors of high orders. The solution of this problem for high order matrices is perfor

Open tube combustion method of organic samples for stable carbon isotope analysis
Autor: Alexander V. Ignatyev, S. I. Kiyashko, Marina V. Reize, Tatiana A. Velivetskaya
Publikováno v: Rapid Communications in Mass Spectrometry. 21:2451-2455
A simple and effective method for the conversion of organic carbon into carbon dioxide for analysis of stable carbon isotopes (delta(13)C) in samples of various organic substances, soils, sedimentary rocks, oils and volatile organic liquids is presen

Palaeotemperature curve for the Late Cretaceous of the northwestern circum-Pacific
Autor: Yasunari Shigeta, Nataliya G. Boriskina, Kazushige Tanabe, Alexander M. Popov, Alexander V. Ignatyev, Yuri D. Zakharov, Haruyoshi Maeda, Tamara B. Afanasyeva
Publikováno v: Cretaceous Research. 20:685-697
In the northwestern circum-Pacific, two main trends in Late Cretaceous temperatures can be recognized. (1) In general, a recurrent warming trend is thought to have begun in the Turonian–Campanian, reaching temperature maxima in the early Late Santo

Fiber optic interferometric sensors using multimode fibers
Autor: S. L. Galkin, V. E. Strigalev, V. A. Nikolaev, Alexander V. Ignatyev
Publikováno v: SPIE Proceedings.
We have considered some problems of applicability of multimode optical fibers in various interferometric configurations for optical fiber sensors development. The analysis was based on theoretical and experimental studies of spatial-temporal coherenc
