The problem of combinatorial optimization is considered in relation to the choice of the location of the location of power supplies when solving the problem of the development of urban distribution networks of power supply. Two methods have been developed for placing power supplies and assigning consumers to them to solve this problem. The first developed method consists in placing power supplies of the same standard sizes, and the second - of different standard sizes. The fundamental difference between the created (...) methods and the existing ones is that the proposed methods take into account all the material of the problem and have specialized methods for coding possible solutions, modified operators of crossing and selection. The proposed methods effectively solve the problem of low inheritance, topological unfeasibility of the found solutions, as a result of which the execution time is significantly reduced and the accuracy of calculations is increased. In the developed methods, the lack of taking into account the restrictions on the placement of new power supplies is realized, which made it possible to solve the problem of applying the methods for a narrow range of problems. A comparative analysis of the results obtained by placing power supplies of the same standard sizes and known methods was carried out, and it was found that the developed method works faster than the known methods. It is shown that the proposed approach ensures stable convergence of the search process by an acceptable number of steps without artificial limitation of the search space and the use of additional expert information on the feasibility of possible solutions. The results obtained allow us to propose effective methods to improve the quality of decisions made on the choice of the location of power supply facilities in the design of urban electrical.

We have had the chance to live through a fascinating revolution in measuring the fundamental empirical cosmological Hubble law. The key progress is analysed: improvement of observational means ; understanding of the biases that affect both distant and local determinations of the Hubble constant; new theoretical and observational results. These circumstances encourage us to take a critical look at some facts and ideas related to the cosmological red-shift. This is important because we are probably on the eve of a new (...) understanding of our Universe, heralded by the need to interpret some cosmological key observations in terms of unknown processes and substances.

New Ukrainian translation of the Preface to the famous Immanuel Kant`s Cri­tique of Pure Reason. Translator Yurii Fedorchenko emphasizes the correctness of the translation of certain propositions of the original text, as well as the adequacy of the reader’s understanding and, accordingly, the need for a correct translation of certain terms of Kant’s philosophy, such as “Vermögen”, “Gebrauch”, “Anwendung”, “Ausführlichkeit”, “ Ziel”, “Zweck”, etc. This translation is accompanied by an analyti­cal article by the translator, which is posted above in (...) the same issue of the magazine “Philosophy of Education”.

The notion of intersemiosis suggests the game relationships between the multiple interacting signifying spheres of culture, but the term can also be fitly applied to the study of certain extraordinary artistic texts. This study makes use of one such book, Julio Cortazar's Around the Day in Eighty Worlds, to show how the sui generis interplay of the book's semantic spheres simultaneously models and renews the complex cultural processes of the production of meaning. This often reprinted and hard-tocategorize book that for (...) years has remained at the outskirts of Latin American culture is also an ideal example to explore the dynamics between the center and periphery of culture as well as the writer's role in the creative renewal of cultural repertoires. By drawing a bridge over the apparent gap between the semiotics of culture and the semiotics of the artistic text, the present study attempts to approximate the critical-creative spirit of the late great theoretician Yurij Lutman.

In the middle of the 18th century, a new fad found its way into the gardens of England's well-to-do: building fake Gothic ruins. Newly constructed castle towers and walls looked like they were already falling apart, even on the first day of their creation. Made of stone, plaster, or even canvas, these "sham ruins" are often considered an embarrassing blip in English architectural history. However, Sham Ruins: A User's Guide expands the specific example of the sham ruin into a general (...) principle to examine the way purposely broken objects can be used both to uncover old truths and invent new ones. Along with architecture, work by Ivan Vladislavić, Tom Stoppard, Alain Mabanckou, Aleksei Fedorchenko, Michael Haneke, and Sturtevant is used to develop this thesis, as well as artifacts such as pre-torn jeans, fake histories, and broken screen apps. Using these examples, one of the key questions the book raises is: What is it that sham ruins ruin? In other words, if real ruins are ruins of what they actually are, then sham ruins should be considered ruins of what they are not. Thus sham ruins are about imposing new meaning where such meaning does not and should not exist. They also can show how things we think are functioning well are actually already broken. Sham ruins do this, and much more, by being lies, ruses, and embarrassments. This is what gives them the power with which we can think about objects in new, unintended ways. (shrink)
