Reflecting the changes to the all-important short circuit calculations in three-phase power systems according to IEC 60909-0 standard, this new edition of the practical guide retains its proven and unique concept of explanations, calculations and real-life examples of short circuits in electrical networks. It has also been completely revised and expanded by 20% to include the standard-compliant prevention of short circuits in electrical networks for photovoltaics and wind energy. By understanding the theory any software allows users to perform all the necessary calculations with ease so they can work on the design and application of low- and high-voltage power systems. This book is a practitioner's guide intended for students, electrical engineers, engineers in power technology, the electrotechnical industry, engineering consultants, energy suppliers, chemical engineers and physicists in industry.

This book provides an understanding of the nature of short-circuit currents, current interruption theories, circuit breaker types, calculations according to ANSI/IEEE and IEC standards, theoretical and practical basis of short-circuit current sources, and the rating structure of switching devices. The book aims to explain the nature of short-circuit currents, the symmetrical components for unsymmetrical faults, and matrix methods of solutions, which are invariably used on digital computers. It includes innovations, worked examples, case studies, and solved problems.

This Circuits and Systems History book fills a gap in published literature by providing a record of the many outstanding scientists, mathematicians and engineers who laid the foundations of Circuit Theory and Filter Design from the mid-20th Century.

A new, philosophically grounded theory of the voice—the voice as the lever of thought, as one of the paramount embodiments of the psychoanalytic object. Plutarch tells the story of a man who plucked a nightingale and finding but little to eat exclaimed: "You are just a voice and nothing more." Plucking the feathers of meaning that cover the voice, dismantling the body from which the voice seems to emanate, resisting the Sirens' song of fascination with the voice, concentrating on "the voice and nothing more": this is the difficult task that philosopher Mladen Dolar relentlessly pursues in this seminal work. The voice did not figure as a major philosophical topic until the 1960s, when Derrida and Lacan separately proposed it as a central theoretical concern. In A Voice and Nothing More Dolar goes beyond Derrida's idea of "phonocentrism" and revives and develops Lacan's claim that the voice is one of the paramount embodiments of the psychoanalytic object (objet a). Dolar proposes that, apart from the two commonly understood uses of the voice as a vehicle of meaning and as a source of aesthetic admiration, there is a third level of understanding: the voice as an object that can be seen as the lever of thought. He investigates the object voice on a number of different levels—the linguistics of the voice, the metaphysics of the voice, the ethics of the voice (with the voice of conscience), the paradoxical relation between the voice and the body, the politics of the voice—and he scrutinizes the uses of the voice in Freud and Kafka. With this foundational work, Dolar gives us a philosophically grounded theory of the voice as a Lacanian object-cause.

Behind our computer screens we are all cyborgs: through fantasy we can understand our involvement in virtual worlds. Cyberspace is first and foremost a mental space. Therefore we need to take a psychological approach to understand our experiences in it. In Interface Fantasy, André Nusselder uses the core psychoanalytic notion of fantasy to examine our relationship to computers and digital technology. Lacanian psychoanalysis considers fantasy to be an indispensable “screen” for our interaction with the outside world; Nusselder argues that, at the mental level, computer screens and other human-computer interfaces incorporate this function of fantasy: they mediate the real and the virtual. Interface Fantasy illuminates our attachment to new media: why we love our devices; why we are fascinated by the images on their screens; and how it is possible that virtual images can provide physical pleasure. Nusselder puts such phenomena as avatars, role playing, cybersex, computer psychotherapy, and Internet addiction in the context of established psychoanalytic theory. The virtual identities we assume in virtual worlds, exemplified best by avatars consisting of both realistic and symbolic self-representations, illustrate the three orders that Lacan uses to analyze human reality: the imaginary, the symbolic, and the real. Nusselder analyzes our most intimate involvement with information technology—the almost invisible, affective aspects of technology that have the greatest impact on our lives. Interface Fantasy lays the foundation for a new way of thinking that acknowledges the pivotal role of the screen in the current world of information. And it gives an intelligible overview of basic Lacanian principles (including fantasy, language, the virtual, the real, embodiment, and enjoyment) that shows their enormous relevance for understanding the current state of media technology.
