Book Description
This second edition of the highly acclaimed RF Power Amplifiers has been thoroughly revised and expanded to reflect the latest challenges associated with power transmitters used in communications systems. With more rigorous treatment of many concepts, the new edition includes a unique combination of class-tested analysis and industry-proven design techniques. Radio frequency (RF) power amplifiers are the fundamental building blocks used in a vast variety of wireless communication circuits, radio and TV broadcasting transmitters, radars, wireless energy transfer, and industrial processes. Through a combination of theory and practice, RF Power Amplifiers, Second Edition provides a solid understanding of the key concepts, the principle of operation, synthesis, analysis, and design of RF power amplifiers. This extensive update boasts: up to date end of chapter summaries; review questions and problems; an expansion on key concepts; new examples related to real-world applications illustrating key concepts and brand new chapters covering ‘hot topics’ such as RF LC oscillators and dynamic power supplies. Carefully edited for superior readability, this work remains an essential reference for research & development staff and design engineers. Senior level undergraduate and graduate electrical engineering students will also find it an invaluable resource with its practical examples & summaries, review questions and end of chapter problems. Key features: • A fully revised solutions manual is now hosted on a companion website alongside new simulations. • Extended treatment of a broad range of topologies of RF power amplifiers. • In-depth treatment of state-of-the art of modern transmitters and a new chapter on oscillators. • Includes problem-solving methodology, step-by-step derivations and closed-form design equations with illustrations.

Book Description
This long-awaited volume presents the work of Elizabeth Lyding Will on the important group of transport amphoras found at Cosa. This town has been widely recognized as a prototypical colony of the later Roman Republic and a source for trade with Gaul and Spain, so this publication of its finds has important implications for archaeologists and historians of the ancient world. Will’s initial work was on Latin amphora-stamps in the eastern Mediterranean, and through the 1960s and 1970s she developed an amphora typology based on materials found in the region and at Cosa. What has not been appreciated is that this typology was not limited to stamped Republican amphoras but also included unstamped vessels, such as imperial Spanish, African, and eastern amphoras dating as late as the fifth century CE. This book shows that Will was far ahead of her time in documenting the Mediterranean trade in commodities carried in amphoras: her work not only provides a record of the amphoras found on the town-site of Cosa, but also includes a comparison between the finds from the port and the town. At the time of Will’s death, her manuscript consisted of a typed catalogue of the amphora stamps from Cosa and an equal number of unstamped vessels, but was missing important elements. On the basis of extensive notes and photographs, Kathleen Warner Slane has reviewed and updated the manuscript, adding type descriptions and footnotes to materials that have appeared since Will’s death as well as a framing introduction and conclusions. Appendices highlight an Augustan amphora dump on the Arx and add a catalogue of the Greek amphora stamps found at Cosa. Cosa: The Roman and Greek Amphoras will be of interest to scholars and students of Rome and its system of colonies, and also to those interested in Greek and Roman archaeology and trade in the ancient world.

Book Description
Multi-body Kinematics and Dynamics with Lie Groups explores the use of Lie groups in the kinematics and dynamics of rigid body systems. The first chapter reveals the formal properties of Lie groups on the examples of rotation and Euclidean displacement groups. Chapters 2 and 3 show the specific algebraic properties of the displacement group, explaining why dual numbers play a role in kinematics (in the so-called screw theory). Chapters 4 to 7 make use of those mathematical tools to expound the kinematics of rigid body systems and in particular the kinematics of open and closed kinematical chains. A complete classification of their singularities demonstrates the efficiency of the method. Dynamics of multibody systems leads to very big computations. Chapter 8 shows how Lie groups make it possible to put them in the most compact possible form, useful for the design of software, and expands the example of tree-structured systems. This book is accessible to all interested readers as no previous knowledge of the general theory is required. - Presents a overview of the practical aspects of Lie groups based on the example of rotation groups and the Euclidean group - Makes it clear that the interface between Lie groups methods in mechanics and numerical calculations is very easy - Includes theoretical results that have appeared in scientific articles
