“The Glass Bead Game” with Igor Volgin: A TV Show about Literature in Modern Culture
No full textThe urgency of the study is determined by the interpretation of TV shows about literature as hybrid forms that appeared during the transition from literature-centrism to media-centrism, solving literature-centric problems via media-centric means. The aim of the work is to carry out a comprehensive analysis of the TV pro- gram about literature “The Glass Bead Game” with Igor Volgin. The work of Pierre Bourdieu “On Television”, and specifically its part devoted to television debates, became the theoretical and methodological basis for the study.
Following the algorithm suggested by the sociologist, the author pays attention not only to the content of the TV show, but also to its structural and formal features, including the figure of the presenter, the set of the invited experts, the peculiarities of the script and editing, and the importance of timing on television. The structural, semiotic, discursive and typological approaches are also used to analyze the show. The following conclusions were obtained as a result of the study. “The Glass Bead Game” is a transmedia (multi-platform) project located on four media platforms and reflecting their communicative advantages and disadvantages. From the genre point of view, the program is defined as a TV talk show, which includes conversations about classic literature works and combines the principles of mass production with a high intellectual level of presentation. The participants of the program (Igor Volgin and the experts invited by him) personify a certain audiovisual section of the Russian humanitarian intelligentsia of the last decade. From the content point of view, the talk show is viewed upon as a collection of interpretations of various classic works within the frame of the “traditional” (hermeneutical) research paradigm. From the formal point of view, “The Glass Bead Game” has not only an established structure, but also factors of variability, providing a diversity of issues. The show uses various television means to make it more spectacular and dynamic. The reception of “The Glass Bead Game” is also analyzed on the professional level and in terms of its popularity with a wide audience. The results of the study can be used in courses on contempo- rary literature and media practices

No full textEffect of Current Efficiency on Electrochemical Micromachining by Moving Electrode
No full textAbstractIn this work, the effect of current efficiency on the electrochemical micromachining by moving electrode is studied theoretically. The Laplace equation for the electric potential and the equation of workpiece surface evolution are used as the mathematical model of the process. A new scheme of solution of free boundary problem for steady-state electrochemical micromachining is proposed. According to the scheme, the initial approximation of the workpiece surface is prescribed. In the course of modeling, the workpiece surface moves in the normal direction at a rate proportional to the discrepancy of the steady-state condition. The effect of various dependences of current efficiency on the local current density is analyzed. As a result of simulation, the dependences of the shape and sizes of machined surface on the current efficiency and the machining parameters are obtained
Effect of Tool-electrode Shape on Uniformity of Electrochemical Deposition and Dissolution on Resistive Workpieces
No full textAbstractThis work is devoted to the theoretical study of the effect of tool-electrode shape and operating conditions on the thickness uniformity of deposited and dissolved metal layer on the resistive workpieces. The Laplace's equation for the potential in the electrolyte solution, the Poisson's equation for the potential in the resistive workpiece, and the equation of metal thickness evolution were used as the mathematical model. The numerical solution was performed using the boundary element and finite element methods. The results of computer modeling demonstrate the effect of operating conditions and tool-electrode shape on the uniformity of metal electrochemical deposition and dissolution
Modeling of Wire Electrochemical Micromachining
No full textAbstractWire electrochemical micromachining (WECMM) is a promising method for the fabrication of various metal parts. In recent years, WECMM has attracted increasing interest, especially for treatment of complex-shaped microworkpieces. By now, the regularities of electrochemical shaping for the complex-shaped workpieces have not been adequately investigated, because the majority of the works, which are devoted to WECMM, are experimental.In this work WECMM is studied theoretically. The Laplace equation for the electric potential and the equation of workpiece surface evolution are used as the mathematical model of the process. A scheme of computer simulation involves the numerical solution of the Laplace equation by the boundary element method; the determination of a new position of workpiece surface with regard for possible topological changes; and the motion of wire tool-electrode along a prescribed trajectory. Various schemes of shaping for the tool-electrodes with various cross-section shapes and various types of motions are analyzed. As a result of simulation, the dependences of the front and side interelectrode gaps on the machining parameters are obtained. They can be used for determining the path of wire tool-electrode in order to obtain the prescribed shape and sizes of workpiece surface

No full textModeling of Formation of Nanostructured Metal Surfaces by Electrodeposition through a Monolayer Colloidal Crystal Mask
No full textAbstractElectrochemical deposition is a feasible and well-controlled method for the formation of various micro- and nanostructures. A rich variety of periodical nanostructures of functional materials with multi-shaped and tunable morphologies can be fabricated by the electrochemical deposition, in particular, using monolayer colloidal crystal (MCC) mask. A mathematical model of the mass-transfer processes and deposit surface evolution during the metal electrodeposition through MCC mask is presented. The mathematical model involves the equations for the potential and deposit surface evolution. The problem was solved numerically by the boundary element method, and the “Level Set” method. The numerical experiments were used to study the effect of parameters, which characterize the mask geometry and the process conditions, on the initial distribution of current density over the deposit surface and the variation of current density distribution in the course of the deposition
