  • Institutional barriers to the development of the knowledge economy

    The formation and effective development of the knowledge economy in the country is possible only with a stable and Mature institutional environment. Indices of the knowledge economy and institutional regime calculated using the world Bank methodology determine the country's readiness for further development. According to the rating, Russia shows a problematic institutional component. The article examines the main institutional problems and barriers, namely institutional traps that hinder the development of the knowledge economy, explains their mechanisms and consequences for the Russian economy, and suggests ways out of them.

    Keywords: knowledge economy, institutional traps, barriers, innovation, economic development, mechanism

  • Assessment and prediction of material properties using molecular modeling

  • On the issue of calculating the steady-state modes of electric power systems

    When determining the locations of compensating devices, it is necessary to make complex calculations that take into account various factors (included in the equations in the form of variables). To get results, calculations are performed repeatedly. Newton's method with coefficients in the form of a Jacobi matrix is widely used. An algorithm for solving the necessary equations by the Gauss method is considered, and the required number of iterations is determined to obtain reliable results.

  • Modification of installation technology for prefabricated space frame units

    The paper explores the opportunity to use tower cranes with a large boom length for installation of space frames configured as prefabricated units. The opportunity to modify the already existing technology by using new tower cranes with a large boom length allows cutting the cost of construction of industrial buildings with flat structural plates. Cost cuts are realized by reducing the scope of works pertaining to installation and dismantling of crane runway as well as crane relocation toward other spans of the building.
