Transient Phenomena in Electrical Power Systems. Problems and Illustrations

Brief Phenomena in electrical energy structures: difficulties and Illustrations offers with the means of calculating the various brief phenomena in electricity structures. Concrete examples are given to teach the nature of the temporary procedures, and the order of importance is derived in a few standard instances.

Bodies and Culture: Discourses, Communities, Representations, Performances

Our bodies and tradition is a suite of latest interdisciplinary examine on our bodies from rising students within the humanities and social sciences disciplines that addresses concerns on the subject of a variety of old and modern contexts, theories, and techniques. studying the variety and functions of our bodies, this quantity specializes in the function of tradition in shaping kinds and conceptions of the corporeal.
