Provides a thorough explanation of the basic properties of materials; of how these can be controlled by processing; of how materials are formed, joined and finished; and of the chain of reasoning that leads to a successful choice of material for a particular application. The materials covered are grouped into four classes: metals, ceramics, polymers and composites. Each class is studied in turn, identifying the families of materials in the class, the microstructural features, the processes or treatments used to obtain a particular structure and their design applications. The text is supplemented by practical case studies and example problems with answers, and a valuable programmed learning course on phase diagrams.

The analysis of silk is a fascinating topic for research in itself but here, focusing on the 9th and 10th centuries, Marianne Vedeler takes a closer look at the trade routes and the organization of production, trade and consumption of silk during the Viking Age. Beginning with a presentation of the silk finds in the Oseberg burial, the richest Viking burial find ever discovered, the other silk finds from high status graves in Scandinavia are discussed along with an introduction to the techniques used to produce raw silk and fabrics. Later chapters concentrate on trade and exchange, considering the role of silk items both as trade objects and precious gifts, and in the light of coin finds. The main trade routes of silk to Scandinavia along the Russian rivers, and comparable Russian finds are described and the production and regulation of silk in Persia, early Islamic production areas and the Byzantine Empire discussed. The final chapter considers silk as a social actor in various contexts in Viking societies compared to the Christian west.

Dr. Greg Zacharias, former Chief Scientist of the United States Air Force (2015-18), explores next steps in autonomous systems (AS) development, fielding, and training. Rapid advances in AS development and artificial intelligence (AI) research will change how we think about machines, whether they are individual vehicle platforms or networked enterprises. The payoff will be considerable, affording the US military significant protection for aviators, greater effectiveness in employment, and unlimited opportunities for novel and disruptive concepts of operations. Autonomous Horizons: The Way Forward identifies issues and makes recommendations for the Air Force to take full advantage of this transformational technology.
