Condition monitoring of engineering plants has increased in importance as engineering processes have become increasingly automated. However, electrical machinery usually receives attention only at infrequent intervals when the plant or the electricity generator is shut down. The economics of industry have been changing, placing ever more emphasis on the importance of reliable operation of the plants. Electronics and software in instrumentation, computers, and digital signal processors have improved our ability to analyse machinery online. Condition monitoring is now being applied to a range of systems from fault-tolerant drives of a few hundred watts to machinery of a few hundred MW in major plants.

Condition monitoring of engineering plant has increased in importance as engineering processes are automated and manpower is reduced. However, electrical machinery receives attention only at infrequent intervals when plant is shut down and the application of protective relays to machines has also reduced operator surveillance.

The Diagram as Paradigm is the first book that looks at medieval diagrams in a cross-cultural perspective, focusing on three regions—Byzantium, the Islamicate world, and the Latin West—each culturally diverse and each closely linked to the others through complex processes of intellectual, artistic, diplomatic, and mercantile exchange.

The volume unites case studies, often of little-known material, by an international set of specialists, and is prefaced by four introductory essays that provide broad overviews of diagrammatic traditions in these regions in addition to considering the theoretical dimensions of diagramming. Among the historical disciplines whose use of diagrams is explored are philosophy, theology, mysticism, music, medicine, mathematics, astronomy, and cosmology. Despite the sheer variety, ingenuity, and visual inventiveness of diagrams from the premodern world, in conception and practical use they often share many similarities, both in construction and application. Diagrams prove to be an essential part of the fabric of premodern intellectual, scientific, religious, artistic, and artisanal life.

Written by experts in the field, the essays in this volume examine the early Christian book from a wide range of disciplines: religion, art history, history, Near Eastern studies, and classics.

This book covers the progress made in the area of wide bandgap semiconductor (WBG) technologies, in particular SiC, with a strong emphasis on their applications torapidly progressing areas such as automotive, aerospace and the whole electrical energy sector. The book is unique in its blend of device functionality and capabilities, technology road maps, as well as addressing the important aspects of real-life applications of these emerging devices. The benefits offered by wide bandgap material devices is enormous, and in the era of more electrification of transport and reformation of the whole energy supply chain this is set to be one of the key defining technologies over the next few decades that will support the whole eco-structure of society in the 21st century, much as silicon has done over the last half of the 20th century.
