Abstract The experience of using reactive inductor machines (RIM) on vehicles is described. Over the past decade, the interest in RIM for the transport industry has significantly increased. One of the promising areas of RIM use is hybrid vehicles. A RIM has a simple design, high reliability and performance. It is capable of operating in motor and generator modes. The world experience in the development of vehicles with RIM has been promising in using this type of electric machines in electric power transmissions of locomotives.

This article discusses the affordances of soundscape composition and how the techniques and approaches of this genre have been embraced as an inter-disciplinary research methodology. Since its emergence from the World Soundscape Project, the concept of soundscape composition has set out to enhance our listening awareness of our soundscapes, inspiring and establishing a discourse that explores a sense of place through sound. Soundscape composition over the past decades has established itself as a popular compositional practice among acousmatic composers utilising compositional techniques that go beyond phonographic representation of acoustic environments. Electroacoustic techniques explore not only the transformation and processing of field recordings but also the spatialisation and performance techniques used to create immersive and realistic soundscapes. These compositional developments since the establishment of the World Soundscape Project have brought this genre of music to a wider audience as it has developed into a cross-disciplinary practice. Soundscape studies methodologies such as soundwalking, listening and recording are being utilised by a broader research cohort outside of soundscape composition. This article provides a survey of recent projects and compositions that incorporate a soundscape and cross-disciplinary approach that reflects a variety of cultural themes and issues within the disciplines of social, political and cultural science.

The Way

One of the most forbidding and yet rewarding challenges in a substantive internationalization of arts scholarship is accounting for the experience and passage of time. The extent to which developments in theatre and performance over the past 150 years have been tied up with the larger social, economic and technological transformations reflexively understood as ‘modernity’ is a key reason an international journal readership is able to find interest and value in scholarship on performances they may not have seen, that are practised in places they have never been. At the same time, any such research – it is tempting to say ‘from outside the West’, but in fact the requirement holds everywhere – must register how the work under discussion complicates an otherwise oversimplified narrative of developmental modernity. This narrative treats a homogenized industrial and postindustrial ‘West’ as having led the way and established a model for how other parts of the world would modernize subsequently. The assumption is quickened in discussions of art because arguably one characteristic of those transformations as they happened in numerous centres of Euro-American power was the role that artists played in giving them aesthetic form and expressing their meanings. This is prominent in the emergence of modernism and the avant-garde, and it is logical that in recent times scholars of modernism have been particularly energetic in questioning the developmental narrative and demonstrating not only how such phenomena were constitutively reliant on processes elsewhere, but also how artistic developments everywhere both informed each other (often inequably) and manifested local and highly contingent characteristics.

Musical robotics is a rapidly growing field, with dozens of new works appearing in the past half decade. This paper explores the foundations of the discipline and how, due to the ability of musical robots to serve as uniquely spatialized musical agents, it experienced a rebirth even in the face of loudspeaker technology's dominance. The growth of musical robotics is traced from its pre-computer roots through its 1970s renaissance and to contemporary installation-oriented sculptures and performance-oriented works. Major figures in the field are examined, including those who in recent years have introduced the world to human/musical robot interaction in a concert setting. The paper closes with a brief speculation on the field's future, with a focus on the increasing ease with which new artists may enter the field.

The World

In the past, linear extrapolations of strategic plans offered promising guides to the future. Managers tried to categorize well-known problems into boxes with strategy labels, the top of a firm’s agenda was steering clear of potential potholes, and there was a choice between clear-cut future options. These strategies no longer work today, and just repeating what we have been done before is not a convincing recipe. The world has become different with multiple and often fuzzy options. In this article, we suggest that companies in different industries have to become more agile. Naturally, agility is not easy to implement as managers fear chaos and confusion. Thus, we introduce agility patterns with different degrees of change. For instance, high-reliability organizations, such as transportation or nuclear energy, are supposed to engage more in gradual change and stick closer to planning. However, we argue that even these companies have to become agile, albeit on a different level. In contrast, companies that exhibit lower system relevance, such as advertising or arts, may strive for agility that involves transformational elements; they can engage in experimentation and play and are more likely to accept inherent chaos in their change strategy. We use the notion of agility patterns for these different degrees of change and show how they help to mitigate the risks that come from either inertia (as a result of linear planning) or experiential chaos (as a result of full agile transformation). Depending on the industry and the degree of change, we distinguish between resilient, versatile and transformational agility patterns. We illustrate each category with examples and highlight how agility patterns can be applied to create value.

Many countries around the world are considering the possibility of a complete transition to electric cars. This raises questions about the capabilities of the existing infrastructure for electricity generation. This paper presents calculations on the example of the Russian power system. It is conventionally accepted that all cars with petrol engine will be run on electricity. To understand how much electricity consumption will change, a calculation technique has been proposed. As initial data, statistics on the production of electricity, petrol and diesel fuel over the past 20 years was used. As methodological approaches, a generalization and calculation were carried out, on the basis of which a theoretical experiment was conducted. The authors concluded that the increase in electricity consumption will be only 5%, which will not create an excessive load on the existing energy infrastructure.

Instrument Control

Advances in camera technology and digital instrument control have meant that in modern microscopy, the image that was, in the past, typically recorded on a piece of film is now recorded directly into a computer. The transfer of the analog image seen in the microscope to the digitized picture in the computer does not mean, however, that the problems associated with recording images, analyzing them, and preparing them for publication, have all miraculously been solved. The steps involved in the recording an image to film remain largely intact in the digital world. The image is recorded, prepared for measurement in some way, analyzed, and then prepared for presentation.Digital image acquisition schemes are largely the realm of the microscope manufacturers, however, there are also a multitude of “homemade” acquisition systems in microscope laboratories around the world. It is not the mission of this tutorial to deal with the various acquisition systems, but rather to introduce the novice user to rudimentary image processing and measurement.

On the Symbolism of Rain in A Farewell to Arms

Farewell To Arms

This paper critically analyzes the symbolic use of rain in A Farewell to Arms (1929). The researcher has applied the Sapir-Whorf Hypothesis as a research tool for the analysis of the text. This hypothesis argues that the languages spoken by a person determine how one observes this world and that the peculiarities encoded in each language are all different from one another. It affirms that speakers of different languages reflect the world in pretty different ways. Hemingway’s symbolic use of rain in A Farewell to Arms (1929) is denotative, connotative, and ironical. The narrator and protagonist, Frederick Henry symbolically embodies his own perceptions about the world around him. He time and again talks about rain when something embarrassing is about to ensue like disease, injury, arrest, retreat, defeat, escape, and even death. Secondly, Hemingway has connotatively used rain as a cleansing agent for washing the past memories out of his mind. Finally, the author has ironically used rain as a symbol when Henry insists on his love with Catherine Barkley while the latter being afraid of the rain finds herself dead in it.

The world-wide use of scleral contact lenses has dramatically increased over the past 10 year and has changed the way that we manage patients with corneal irregularity. Successfully fitting them can be challenging especially for eyes that have significant asymmetries of the cornea or sclera. The future of scleral lens fitting is utilizing corneo-scleral topography to accurately measure the anterior ocular surface and then using software to design lenses that identically match the scleral surface and evenly vault the cornea. This process allows the practitioner to efficiently fit a customized scleral lens that successfully provides the patient with comfortable wear and improved vision.

National Borders

Over the past century, democracy spread around the world in turbulent bursts of change, sweeping across national borders in dramatic cascades of revolution and reform. This book offers a new global-oriented explanation for this wavelike spread and retreat—not only of democracy but also of its twentieth-century rivals, fascism, and communism. The book argues that waves of regime change are driven by the aftermath of cataclysmic disruptions to the international system. These hegemonic shocks, marked by the sudden rise and fall of great powers, have been essential and often-neglected drivers of domestic transformations. Though rare and fleeting, they not only repeatedly alter the global hierarchy of powerful states but also create unique and powerful opportunities for sweeping national reforms—by triggering military impositions, swiftly changing the incentives of domestic actors, or transforming the basis of political legitimacy itself. As a result, the evolution of modern regimes cannot be fully understood without examining the consequences of clashes between great powers, which repeatedly—and often unsuccessfully—sought to cajole, inspire, and intimidate other states into joining their camps.

The Ideal

This book lays out a vision for how we should theorize about justice in a diverse society. It shows how free and equal people, faced with intractable struggles and irreconcilable conflicts, might share a common moral life shaped by a just framework. The book argues that if we are to take diversity seriously and if moral inquiry is sincere about shaping the world, then the pursuit of idealized and perfect theories of justice—essentially, the entire production of theories of justice that has dominated political philosophy for the past forty years—needs to change. Drawing on recent work in social science and philosophy, the book points to an important paradox: only those in a heterogeneous society—with its various religious, moral, and political perspectives—have a reasonable hope of understanding what an ideally just society would be like. However, due to its very nature, this world could never be collectively devoted to any single ideal. The book defends the moral constitution of this pluralistic, open society, where the very clash and disagreement of ideals spurs all to better understand what their personal ideals of justice happen to be. Presenting an original framework for how we should think about morality, this book rigorously analyzes a theory of ideal justice more suitable for contemporary times.
