Comparison of the design features of an electromechanical converter with a discrete secondary part with the classical installation options

In the present article, devices with a discrete secondary part are considered, which act as means of intensifying many technological processes of mixing and dispersing materials. In the classic version, the device has a number of disadvantages. To eliminate the shortcomings, the design of an electromechanical converter with a discrete secondary part was developed, which differs from the classical version by a magnetic system capable of implementing the process of controlling the movement of a large set of ferromagnetic elements along a pre-developed trajectory.

Eurasianism and Foreign Policy of Russia

In order to determine the possibilities of wider application of the ideas of Eurasianism in the foreign policy of Russia, including the EAEU, but not limited to it, an analysis of various methods and approaches used for integration processes is carried out. At the same time, the current geopolitical situation and the factors of multi-vector approach in international relations are taken into account. It is also proposed to take in attention the role of identity in a broad sense as a political attraction. At the same time, various problems at the organizational, social, humanitarian and economic levels are also considered. The broad security factors that also play a role in the Eurasian integration are also taken into account. The relevance of this study is due not only to the implementation of strategic directions within the EAEU, but also to the general course towards multipolarity that Russia is pursuing. In addition, the crisis of liberal democracy in the West provides an additional opportunity for Russia to implement its own ideas and doctrines at the international level. The author believes that Eurasianism, including its classical version, can become one of the imperatives of Russia’s foreign policy.

A Concept of Risk Prioritization in FMEA Analysis for Fluid Power Systems

FMEA analysis is a tool of quality improvement that has been widely used for decades. Its classical version prioritizes risk of failure by risk priority number (RPN). The RPN is a product of severity (S), occurrence (O), and detection (D), where all of the factors have equal levels of significance. This assumption is one of the most commonly criticized drawbacks, as it has given unreasonable results for real-world applications. The RPN can produce equal values for combinations of risk factors with different risk implications. Another issue is that of the uncertainties and subjectivities of information employed in FMEA analysis that may arise from lack of knowledge, experience, and employed linguistic terms. Many alternatives of risk assessment methods have been proposed to overcome the weaknesses of classical FMEA risk management in which we can distinguish methods of modification of RPN numbers of employing new tools. In this study, we propose a modification of the traditional RPN number. The main difference is that severity and occurrence are valued based on subfactors. The detection number remained unchanged. Additionally, the proposed method prioritizes risk in terms of implied risk to the systems by implementing functional failures (effects of potential failures). A typical fluid power system was used to illustrate the application of this method. The method showed the correct failure classification, which meets the industrial experience and other research results of failures of fluid power systems.

Powers, possibility, and the essential cosmological argument

One classical version of cosmological argument, defended famously by Thomas Aquinas and Duns Scotus, deduces the existence of a First Cause from the existence of a particular sort of causal series: one that is ‘essentially ordered’. This argument has received renewed defence in recent work by Feser (2013), Cohoe (2013), and Kerr (2015). I agree with these philosophers that the argument is sound. I believe, however, that the standard defence given of the ECA in these philosophers can be complemented by a formulation that appeals to the powers theory of possibility. This approach to possibility has been defended in recent years by, for example, Pruss (2002), Jacobs (2010), and Vetter (2015). In this article, I show how this modal theory allows us to defend the ECA in a way that is dialectically advantageous as well as clarifying.

Note on the Intuitionistic Logic of False Belief

In this paper we analyse logic of false belief in the intuitionistic setting. This logic, studied in its classical version by Steinsvold, Fan, Gilbert and Venturi, describes the following situation: a formula $\varphi$ is not satisfied in a given world, but we still believe in it (or we think that it should be accepted). Another interpretations are also possible: e.g. that we do not accept $\varphi$ but it is imposed on us by a kind of council or advisory board. From the mathematical point of view, the idea is expressed by an adequate form of modal operator $\mathsf{W}$ which is interpreted in relational frames with neighborhoods. We discuss monotonicity of forcing, soundness, completeness and several other issues. We present also some simple systems in which confirmation of previously accepted formula is modelled.

A Multistate Adsorption Model for the Adsorption of C14EO4 and C14EO8 at the Solution/Air Interface

The dynamic and equilibrium properties of adsorption layers of poly (oxyethylene) alkyl ether (CnEOm) can be well described by the reorientation model. In its classical version, it assumes two adsorption states; however, there are obviously surfactants that can adsorb in more than two possible conformations. The experimental data for C14EO4 and C14EO8 (dynamic and equilibrium surface tensions and surface dilational visco-elasticity as measured by bubble profile analysis tensiometry) are used to verify if a reorientation model with more than two possible adsorption states can better describe the complete set data of CnEOm adsorption layers at the water/air interface. The proposed refined theoretical model allows s different states of the adsorbing molecules at the interface. The comparison between the model and experiment demonstrates that, for C14EO4, the assumption of s = 5 adsorption states provides a much better agreement than for s = 2, while for C14EO8, a number of s = 10 adsorption states allows an optimum data description.

MODERN DEMOCRACY AND EXPANDING THE DEMOCRATIC EXPERIENCE

The article examines some political and socio-economic asumptions for the establishment of modern democracy in its classical version and its defining elements. Particular attention is paid to the analysis of topics on the expansion of the democratic experience in several European states and on the American continent (England, France and the USA) from the XVII-XVIII centuries, during which the birth of modern liberal democracy takes place. It is concluded that modern democracy is based on three historical (political) models from the XVII-XIX centuries (English, French and American), closely related to the form of government (monarchy, republic), state structure (centralized or federal), political regime of government (democratic and undemocratic) or various historical and geopolitical conjunctures.

Lights Out on graphs

We model the Lights Out game on general simple graphs in the framework of linear algebra over the field $$\mathbb{F}_{2}$$ F 2 . Based upon a version of the Fredholm alternative, we introduce a separating invariant of the game, i.e., an initial state can be transformed into a final state if and only if the values of the invariant of both states agree. We also investigate certain states with particularly interesting properties. Apart from the classical version of the game, we propose several variants, in particular a version with more than only two states (light on, light off), where the analysis relies on systems of linear equations over the ring $$\mathbb{Z}_{n}$$ Z n . Although it is easy to find a concrete solution of the Lights Out problem, we show that it is NP-hard to find a minimal solution. We also propose electric circuit diagrams to actually realize the Lights Out game.

Sonatas № 2 end № 9 as Milestones in the Evolution of the Piano Style of A. Scriabin

The article is devoted to the consideration of two piano sonatas by A. Scriabin, representing in a complex the peculiarities of his piano style as an integral phenomenon. The two-part sonata No. 2, classified as a musical landscape, is considered in comparison with the performing versions proposed by S. Richter and V. Ashkenazy. The one-part Sonata No. 9, called “Black Mass”, is considered in comparison with the performing interpretations of V. Sofronitsky and V. Horowitz. It is noted that the Scriabin’s piano style is inherently mixed, compositional and performing, and its grandiose macrocycle of 10 sonatas appears as a compendium of the principles of piano thinking for the post-romantic era. The universalism of Scriabin’s writing is confirmed using the comparative method of analysis, for the first time proposed in this article in relation to the works under consideration. It was revealed that the style in music appears as “a system of stable features of musical phenomena, a way of their differentiation and integration at various levels” (S. Tyshko). The style is distinguished by a tendency to identify the individual, unique, “humanistic” in the broad sense of the word and has a hierarchical structure, within which there is a level characterized as “the style of any kind of music” (V. Kholopova), among which the piano style stands out. Scriabin’s piano sonatas combine the categories of “instrument style”, “author’s style” and “performer’s style” at the style level. It was revealed that the figurative and artistic duality of the Second sonata is reflected in the interpretations presented by S. Richter (the “classical” version, focused on the exact observance of the author’s text remarques, sounding in some places even like in Beethoven’s works), and V. Ashkenazy (the “romantic” version containing a whole complex of articulatory means added by the performer, most of all close to Chopin’s “sonic placers”). The main factor that determines the peculiarities of the performance of the Ninth sonata is the transfer of the playing of harmonic timbre-colors, in which the melodic horizontal turns out to be inert in itself and manifests itself only in harmonic lighting in combination with articulatory attributes. It is noted that A. Scriabin creates in the Ninth sonata actually a special type of texture, accentuating the parameter of depth, based on the stereophonic effect “further — closer”. In the conclusions on the article, it is noted that the stylistic “arch” of two Scriabin’s sonatas highlighted in it helps to comprehend the holistic character and contextual connections of the sonata-piano style of the great Russian composer-innovator, to find “keys” to actual interpretations of his other piano sonatas, an example of which is analyzed interpretation samples of such masters as V. Sofronitsky and V. Horowitz (Ninth sonata) and S. Richter and V. Ashkenazy (Second sonata).
