"Shell Theory" by Wilhelm Flügge is a comprehensive textbook on the mechanics of elastic shells. It is a revised and expanded version of the author's earlier work, offering detailed explanations of fundamental concepts and equations. The book covers various topics including membrane theory, bending theory of shells of revolution, and buckling. While the content is thorough, the bibliography is criticized for lacking references and for being more of a review than a historical account. The book is well-organized, well-printed, and recommended for both practical designers and researchers. "Multivariable Systems" by M. D. Mesarovic is a monograph on control theory. It discusses the control of complex systems and the synthesis problem, but is criticized for being loosely organized and imprecise in its results. "The Dynamic Behavior of Thermoelectric Devices" by Paul E. Gray is a technical book on thermoelectric devices. It is written for those interested in the detailed performance and automatic control of such devices. The book is well-structured and presents sound analysis, though it lacks experimental data. It is considered ahead of its time. "Electronic Processes in Solids" by P. Aigrain, R. J. Coelho, and G. Ascarelli is a concise textbook on electronic processes in solids. It covers crystal lattice dynamics and electrical conduction in semiconductors and metals. While it is useful for those already familiar with the subject, it lacks detailed references and is too simplified for beginners."Shell Theory" by Wilhelm Flügge is a comprehensive textbook on the mechanics of elastic shells.
