The Theory of Fractals as an Effective Tool for Solving Applied (engineering) Problems
Authors: Savostyanova O V , Vyacheslavova O F
Published: April 2022

Creation of surfaces with specific properties necessary for stable product operation is an urgent need for the surface quality management of such products. Surface roughness influences joint surface performance, also influences fatigue durability and connection tightness, and in motionless connections durability depends on size of part roughness. Fractal analysis allows to estimate surface roughness irrespective of the form of its elements and distribution density that would give universality for estimation.
Information Component of Competitiveness Recovery of Russian Small and Medium Enterprises
Authors: Rognova O V , Igumnov V M , Goncharova A A
Published: April 2022

The paper considers the problems of competitiveness recovery of small and medium enterprises (SMEs). As a tool to solve these problems we propose to use the International financial reporting standards (IFRS) for SMEs. It is also shown that application of the given standards by the Russian SMEs will allow them to create the high-quality information basis. Such information is characterized with demanded completeness of financial position and results of a company business. Also, we analyzed the basic differences between IFRS for SMEs from «full IFRS» and named the basic advantages of application IFRS for SMEs. We also consider prospects and difficulties of adoption of the given standards in Russia.
