Concept for Construction of Unmanned Ferry Lines on Russia’s Inland Waterways

This article considers the prospects of building highly automated ferry lines on the internal waterways of Russia. To do this, the authors used the engineering-cybernetical approach to determine the basic provisions of the concept for the construction of unmanned ferry lines. The key provisions of the concept account for the integration of unmanned ferry lines in the river information and communications triad based on the hierarchical principle: the corporate river information and communications service - the river information service - the automated ship-traffic control system. The authors consider the prospects of using unmanned ferry lines on rivers where the navigation and information support for the unmanned ferry can be provided using radio technical facilities covering both the points of departure and destination. The authors also reviewed the arrangement of unmanned ferry lines for situations where the departure point and the destination are far from each other. This type of unmanned ferry line is suitable for reservoirs or large lakes.Finally, the research work also provides a rationalization of the selection of the automation level for unmanned ferry lines following the terminology used by the work team for inland water transport of the Committee for the Inland Water Transport of the UN Economic Commission for Europe (UNECE).

Experimental study of the explosive welding process applicability for train weight decreasing

For the weight decreasing of the trains, it needs to use a new construction conception. For the weight decreasing of the trains, it needs to use a new construction conception, which means a hybrid material construction. The new conception (steel and aluminium for the vehicle construction) requires a suitable welding process for joining the steel with aluminium. Explosive welding is a suitable process to realize this idea. The authors attempt to examine this possibility by experimental methods and suggest a suitable solution for the reduction of the train’s weight. The authors made explosive welding experimental tests to join aluminium (EN-AW-6082) and low carbon steel (EN 10025 S235J2). The cladding of the test samples was made by an explosive welding process. The welded joint suitability was tested by destructive and non-destructive tests. It was tested the joint cross-section microstructure by microscopy. Based on the results it can declare that explosive welding is a suitable process to realize hybrid train construction.

Investigation model of sensing, seizing and reconfiguring capabilities

The dynamic capabilities view came to life as an enhancement of the resource based-view (RBV) and became the most prolific research stream of the resource-based approaches, with most critics pinpointing definitional issues, contradictory interpretations, and tautological assumptions as issues to solve before the view could become a theory. This research lays its foundations in the creation of a model which has the fundamental constructs of sensing, seizing and reconfiguring capabilities complemented by exploration and exploitation concepts of organisational ambidexterity constructs. To assess the applicability of this model a qualitative approach method is used by applying 21 semi-structured interviews in Portugal. The outcome of these interviews presented a set of capabilities that companies should attempt to properly sense, seize and reconfigure to develop dynamic capabilities. The main contribution to the field of strategy is a proposal of an investigation model that suggests a link between the two constructs of sensing/seizing, and exploration/exploitation.

Integrated Prescriptive Maintenance System (PREMSYS) for Construction Equipment Based on Productivity

It is now imperative to create smart systems that prevent mechanical damage through timely preventive maintenance, particularly in construction projects with strict time schedules and budgets. Construction equipment is the largest capital investment for construction companies. Proper maintenance is of major importance for efficiency, productivity, minimization of equipment costs, and environmental management. The aim of this study is to propose an integrated smart system that will monitor the condition based on productivity of the equipment and will provide diagnostic data, helping to optimize the production process, achieve timely maintenance and increasing the expected “economic” life of the equipment. At the same time, it will positively provide the concept for sustainable or green construction with the minimization and elimination of harmful effects on the environment and on the human. The system will include sensors, placed on specific construction equipment components, and will collect measurements for their use and condition, through real-time data export. These data will then be sent using wireless networks to a main server. Extraction of performance measurements and machine learning (ML) data processing will determine when the equipment needs predictive maintenance and repair. Proper, timely and prescriptive maintenance of construction equipment will reduce their environmental footprint and any human harmful emissions, while saving energy during their operating phase and optimizing production processes through monitoring “dead” time.

Effect of turbulence models and cavitation intensity on the motive and suction nozzle mass flow rate prediction during a non-equilibrium expansion process in the CO2 ejector

A variety of ejector constructional concepts can be effectively examined by advanced numerical tools. The development of the modelling techniques of the two-phase meta-stable expansion process in the CO2 ejector motive nozzle provides the detailed flow data of the primary stream. However, the complexity of the entrainment processes in the mixing section still requires attention for the accurate prediction of the suction nozzle flow. Hence, in this paper, an analysis of four turbulence models and cavitation phenomena (four intensity levels) in the CO2 ejector was performed on the basis of the calibrated non-equilibrium expansion model of the ejector motive nozzle. Twenty-three motive nozzle points from the subcritical range (from 50 bar to 70 bar and 8 °C to 23 °C) were coupled with the evaporation temperature of -6 °C and two pressure lift levels (3 bar and 6 bar). Simulations of 460 cases were validated using data from the CO2 ejector refrigeration unit with a 50-kW cooling capacity. The vapour quality distribution in the motive nozzle with cavitating evaporation was described in terms of the primary pressures and the considered turbulence models. An influence of the turbulence formulation on the secondary stream behaviour in the mixing zone was also investigated regarding the suction nozzle mass flow rate. Finally, the proposed model of the CO2 ejector was characterised by the mass flow rate prediction discrepancy at an average level of 4.6% and 12.3% for the motive and suction nozzle, respectively.

Eliot Borenstein. Plots against Russia: Conspiracy and Fantasy after Socialism. Ithaca, NY: Cornell University Press, 2019

Eliot Borenstein has contributed a rich and insightful study of conspiratorial narratives in Russian films, media, and fiction to the growing scholarly field of post-Soviet conspiracy theory (Astapova et al. 2020; Gentile and Kragh 2022; Yablokov 2018) describing how these narratives function to construct conceptions of Russia’s statehood, identity, and destiny. As the book’s title—Plots against Russia: Conspiracy and Fantasy after Socialism—encapsulates, Borenstein identifies attacks against Russia or “Russianness” as the central theme of fictional and nonfictional conspiratorial narratives about Russia’s fate, the so-called Russia narratives. However, the author is quick to assert that his study is neither a “demonization of Putin” (p. ix) nor an expression of Russophobia but the result of years of observation of how ideological fantasies created in the cultural field interact with attempts to formulate a legitimizing myth about “the country’s political destiny” (p. xi). The motivation to write this book stems from the fact that under the current Russian government conspiracy narratives have moved from the fringes closer to the center of the cultural and political scene. Ideological narratives are certainly not unique to Russia, considering that all ideology is an internally consistent fantasy (pp. xi, 13), and are not an invention of President Vladimir Putin’s propaganda department, as Borenstein points out several times; rather they were already circulating in mass culture and rose to prominence during Putin’s third term as president because he was able to seize on prevailing perceptions.

INNOVATIVE DIRECTIONS OF UPDATING THE OPERATING SYSTEMS OF CONSTRUCTION COMPANIES IN AN UNSTABLE BUSINESS ENVIRONMENT OF THE PROJECT

The article investigates the target principles of information modeling concepts in construction (BIM) as an innovative direction of updating the operating systems of construction companies in an unstable economic business environment. Based on the world experience, the preconditions and necessity of introduction of the concept of digital transformation of construction organizations are determined and substantiated. The main obstacles to the digital transformation of construction organizations are identified and characterized: transformational, innovative and managerial. The main stages of formation of a successful digital strategy of a construction organization are formed. To develop a unified vision of the digital transformation of the organization, it is proposed to radically restructure the processes in order to get the most out of digitalization, staff training and recruitment, taking into account the requirements of their digital literacy. The difficulties and benefits that may arise when implementing information modeling are analyzed and systematized. The competitive advantages that participants of the investment and construction process receive from the use of BIM are formulated. Information modeling technologies in construction can be an important tool for big data analysis, information generation and knowledge, because after the completion of each stage of the construction project remains large data sets. Accumulated data can be a corporate asset, the acquisition and use of which allows you to make better forecasts and make the right management decisions. In addition, the knowledge gained in the project and tested in practice can be considered more reliable than the data of experiments or simulations, because they contain more basic knowledge of reality.

Limit theorems for Floyd's triangle: a new approach to not a new problem

Floyd's triangle is often presented to computer science students as an exercise or example to illustrate the concepts of text formatting and loop constructs. The paper proposes to look at an object from a different angle and to examine limit theorems for the numbers of generalized Floyd's triangles. Tasks of this type can be used as exercises in study programs of mathematics and informatics (couses of probability theory and combinatorics). It would help to master the appropriate proof techniques and mathematical apparatus. The article proposes a series of possible problems and their proof schemes.

인간 두뇌 사고유형 평가 (Human Brain Thinking Style; HBTS)의 타당화 연구

In this study, we used the Human Brain Thinking Style which is based on the Brain Thinking Style Assessment developed by Benziger to examine the developmental characteristics of thinking style in child and/or adolescent, and to make sure it reflects the characteristics of the those age groups. So this study investigated the distribution of thinking style and the patterns of change according to age of school-age children and adolescents at Withbrain Reseach Institute in Korea nationwide for five years. As a result, there was a significant difference between the four indicators of Human Brain Thinking Style according to age (p <.001), and each indicator varied with age (p <.001). In addition, a result of analyzing the Human Brain Thinking Style index scores according to age shows that there was a significant difference according to age in all indicators (p <.001), especially that left anterior brain and right posterior brain showed a significant difference before and after 13 years of age (p <.05). In other words, these results reflect the characteristics of adolescent in which the human brain develops rapidly, it is meaningful because it provides a basis for constructive concept and validity of Human Brain Thinking Style.

Features of translation of various emphatic constructions in the technical text

This article discusses various types of emphatic constructions and emphatic intensifiers, characteristic of the English language and frequently found in scientific texts, as well as their translation options from English into Russian. The concept of emphatic constructions, widely used in linguistics in general, is defined. The term «emphasis» is understood by linguists as a natural phenomenon of emotionally colored speech. Differentiation between such concepts as expressiveness and emotionality is carried out. The ways of conveying expressiveness through emotional or logical intensification of speech with the help of morphological, syntactic and word-formation forms of language are considered. The features and methods of translating emphatic constructions from English into Russian are analyzed, taking into account the use of lexical, grammatical and lexicogrammatical language tools. The difficulties of translating emphatic constructions that students of technical higher educational institutions may encounter when translating technical texts are described. Examples of the use of various emphatic constructions and emphatic intensifiers in scientific texts in the field of mechanical engineering are given, including such constructions as inversion, conditional sentences of the second and third types, constructions with double negation, the use of emphatic do. Students of technical higher educational institutions are given recommendations on the options for translating emphatic constructions and emphatic intensifiers from English into Russian, the correctness of the rendering of which affects the adequacy of the translation and is of direct importance for the most complete and accurate representation of the original text in the target language

The concept of non-contractual obligations in inheritance law: international legal experience

The article is devoted to the study and analysis of such areas of civil law as non-contractual structures, within the inheritance law of individual European Union countries, the emergence, development and implementation of such structures in regulations governing the inheritance procedures of countries such as Poland, Czech Republic, Republic of Lithuania and the Republic of Latvia. The purpose of the study in the monograph is a comprehensive analysis of the nature and specifics of legal and doctrinal bases of regulation and practice of non-contractual constructions in the inheritance law of individual EU countries (Poland, Czech Republic, Lithuania, and Latvia). As a result of the study the concept of non-contractual constructions of inheritance law is formed in the work. The types of non-contractual constructions, first of all their dialectical classification, architecture and place in the system of inheritance law are singled out and analyzed. An analysis of their identification and separation in different states, depending on the legal family, traces the integrity of the fundamental structure of knowledge about the obligatory rights of the testator within the will, heirs and beneficiaries in their biocentric expression and in the context of social ties. Emphasis is placed on rethinking and solving some problems in inheritance law, from the point of view of new world realities.

Efficient bilingual lexicon extraction from comparable corpora based on formal concepts analysis

AbstractBilingual corpora are an essential resource used to cross the language barrier in multilingual natural language processing tasks. Among bilingual corpora, comparable corpora have been the subject of many studies as they are both frequent and easily available. In this paper, we propose to make use of formal concept analysis to first construct concept vectors which can be used to enhance comparable corpora through clustering techniques. We then show how one can extract bilingual lexicons of improved quality from these enhanced corpora. We finally show that the bilingual lexicons obtained can complement existing bilingual dictionaries and improve cross-language information retrieval systems.

Fragmenting Monumentality: Discontinuity and Incompleteness in Mahler’S ‘Der Abschied’

Abstract In this article I explore the confluence of Gustav Mahler’s affiliation with a Jewish minority and his approach to musical form and expression. To this end, I devise a theoretical framework that combines Gilles Deleuze and Félix Guattari’s theory of Minor literature with current theories of musical form and analyse selected excerpts from ‘Der Abschied’, the Finale of Mahler’s Das Lied von der Erde (1909). While ‘Der Abschied’ aspires towards monumental expression, it rejects its own realization as a musical monument through musical and textual ambiguities. By means of musical analysis I illustrate how discontinuous and fragmented motion in the musical realm undermines the materialization of apotheotic culminations and negates the interpretative framework of monumentality. Against that background, I then compare Mahler’s formal approach to Kafka’s poetics—the prototype of ‘Minor literature’—and discuss how their ‘Minor works’ concurrently appropriate and subvert the Romantic concept of monumentality and related constructs.

Robustness of spontaneous cascading dynamics driven by reachable area

Different from the previous research framework of cascading failure driven by intentional attack or random failure, this paper considers the occurrence of cascading failure from a new perspective, i.e., the spontaneous phenomenon of cascading failure. When the network changes from the low peak period to the high peak period, the global distribution of load changes, which leads to the cascading failure of the network. This phenomenon is called the spontaneous phenomenon of cascading failure. We introduce the concept of reachable region and construct a new cascading failure model, which mainly focus on how the dynamic changes of reachable area drive the dynamic behavior of cascade failures. Through simulation on two infrastructure networks, we found that: (1) The size of reachable area is positively correlated with network robustness. The larger the reachable area is, the smaller the load fluctuation of the whole network is, and the cascading failures are more easily alleviated and the network robustness is higher. But when the edge load capacity increases, the robustness of the network is not necessarily improved, which indicates the existence of capacity paradox. (2) The size of reachable area is negatively correlated with network capacity redundancy. The larger the reachable area is, the lower the capacity redundancy of the whole network will be and the less network resources will be wasted. (3) Combining with the network topology and the phenomenon of “key edge” we find that the edge with less betweenness centrality usually needs to invest higher resource protection.

The Real Problem with Hypothetical Constructs.

A recent discussion in this journal revolved around the issue of whether postulating internal clocks is harmful or beneficial to scientific psychology, and how. I argue that this and other discussions on the topic have yet to address the real problem: The concept of a hypothetical construct is unintelligible. Psychologists agree that all entities that constitute hypothetical constructs are unobservable, importantly different from observable entities, including overt behavior and its environment. The root issue at hand here, then, is the observable-unobservable distinction. Psychologists have implicitly but erroneously taken it for granted as sufficiently unproblematic to warrant meaningful discussions based on it, when in fact it is a pernicious untenable remnant of logical positivism. All previous discussions of hypothetical constructs in psychology have overlooked arguments against this view in the philosophy of science. These arguments are sufficiently compelling to at least question, if not cease altogether, talk of observability, unobservability, and HCs in psychology as useless, even harmful.

Non-OPC binder based on a hybrid material concept for sustainable road base construction towards a low-carbon society

In this study, a non-OPC binder as a cementless material for a road base stabilizer was established based on a hybrid material concept between the pozzolanic and the alkali-activated materials. Solid sodium hydroxide (NaOH) was used as an alkali additive in a dry mixing process to compensate for the early strength in a pozzolanic-based material matrix with its intrinsic property of delaying the strength gain. Effects of varied NaOH concentrations on the fly ash (FA) and hydrated lime (HL) mixes to generate such a non-OPC binder were investigated through the mechanical properties and microstructure observations. The selected non-OPC binders were then mixed with the road base aggregate to evaluate non-OPC-based mixtures' properties against the road base material specifications. The results revealed that the non-OPC binder, the FA–HL mix (FA:HL = 90:10 by weight) with the NaOH content of 3.5% wt by dry aggregate mass, provided the most effective mechanical properties an entire network of gel and needles-sharp cementitious products. Based on the pavement design conducted in this study, the flexible pavement with the non-OPC base layer provided a significantly lower cost and GHG emission than those of the OPC-based material as a benchmark. This non-OPC binder with a hybrid material concept reveals a great potential to be a cleaner product in road construction and rehabilitation for a new era of our low-carbon society.

Does Product Semantics Matter in Stimulating Impulse Buying Behavior for Internet Products?

Design-driven innovation has become the source of the third-dimensional innovation driving force behind technology and outside the market, aiming to explore breakthrough innovation in product semantics for Internet products. This research tries to define the concept of product semantics and construct a consumer purchase decision model for Internet products with product semantic perception as the antecedent variable. In addition, how product semantics could stimulate consumers' expected regret and impulse purchase for Internet products is explained. The research finds that product semantic perception significantly affects consumers' expected inaction regret, which promotes their impulse purchase intention for Internet products; and expected inaction regret partially mediates between product semantic perception and impulse purchase intention. Self-control ability of consumers negatively moderates the relationship between their expected inaction regret and impulsive purchase intention for Internet products. Thus, the “non-use function” design of product semantics can effectively meet and lead the spiritual and cultural needs in hedonistic Internet shopping for consumers.
