High Temperature Polymer Dielectrics Overview on how to achieve polymer dielectrics at high temperatures, with emphasis on diverse applications in various electrical insulation fields High Temperature Polymer Dielectrics: Fundamentals and Applications in Power Equipment systematically describes the latest research progress surrounding high-temperature polymer dielectric (HTPD) materials and their applications in electrical insulation fields such as high-temperature energy storage capacitors, motors, packaging, printed circuit board, new energy power equipment, and aerospace electrical equipment. The comprehensive text provides a description of the market demand and theoretical research value of HTPDs in electrical equipment and enables readers to improve the performance and design of existing HTPD materials, and to develop efficient new high temperature polymer dielectric materials in general. Specific sample topics covered in High Temperature Polymer Dielectrics include: Thermal and electrical properties of high-temperature polymers, and the excellent thermal stability, mechanical properties, and long service life of polymer dielectrics Why fluorinated polymers are more thermally stable than their corresponding hydrogen-substituted polymers Static Thermomechanical Analysis (TMA), a technique for measuring the functional relationship between the deformation of the materials and the temperature and time under different actions Polyetheretherketone (PEEK), a semi-crystalline polymer material with ether bonds and ketone carbonyl groups in molecular chains Providing a complete overview of the state-of-the-art high temperature polymer dielectrics, with a focus on fundamental background and recent advances, High Temperature Polymer Dielectrics is an essential resource for materials scientists, electrical engineers, polymer chemists, physicists, and professionals working in the chemical industry as a whole.

The demand for high-performance submarine power cables is increasing as more and more offshore wind parks are installed, and the national electric grids are interconnected. Submarine power cables are installed for the highest voltages and power to transport electric energy under the sea between islands, countries and even continents. The installation and operation of submarine power cables is much different from land cables. Still, in most textbooks on electrical power systems, information on submarine cables is scarce. This book is closing the gap. Different species of submarine power cables and their application are explained. Students and electric engineers learn on the electric and mechanic properties of submarine cables. Project developers and utility managers will gain useful information on the necessary marine activities such as pre-laying survey, cable lay vessels, guard boats etc., for the submarine cable installation and repair. Investors and decision makers will find an overview on environmental aspects of submarine power cables. A comprehensive reference list is given for those who want further reading.

An alphabetically organized encyclopedia that provides both a history of military communications and an assessment of current methods and applications. Military Communications: From Ancient Times to the 21st Century is the first comprehensive reference work on the applications of communications technology to military tactics and strategy—a field that is just now coming into its own as a focus of historical study. Ranging from ancient times to the war in Iraq, it offers over 300 alphabetically organized entries covering many methods and modes of transmitting communication through the centuries, as well as key personalities, organizations, strategic applications, and more. Military Communications includes examples from armed forces around the world, with a focus on the United States, where many of the most dramatic advances in communications technology and techniques were realized. A number of entries focus on specific battles where communications superiority helped turn the tide, including Tsushima (1905), Tannenberg and the Marne (both 1914), Jutland (1916), and Midway (1942). The book also addresses a range of related topics such as codebreaking, propaganda, and the development of civilian telecommunications.

During the nineteenth century, Britain became the first gaslit society, with electric lighting arriving in 1878. At the same time, the British government significantly expanded its power to observe and monitor its subjects. How did such enormous changes in the way people saw and were seen affect Victorian culture? To answer that question, Chris Otter mounts an ambitious history of illumination and vision in Britain, drawing on extensive research into everything from the science of perception and lighting technologies to urban design and government administration. He explores how light facilitated such practices as safe transportation and private reading, as well as institutional efforts to collect knowledge. And he contends that, contrary to presumptions that illumination helped create a society controlled by intrusive surveillance, the new radiance often led to greater personal freedom and was integral to the development of modern liberal society. The Victorian Eye’s innovative interdisciplinary approach—and generous illustrations—will captivate a range of readers interested in the history of modern Britain, visual culture, technology, and urbanization.
