This proven and internationally recognized text teaches the methods of engineering design as a condition of successful product development. It breaks down the design process into phases and then into distinct steps, each with its own working methods. The book provides more examples of product development; it also tightens the scientific bases of its design ideas with new solution fields in composite components, building methods, mechatronics and adaptronics. The economics of design and development are covered and electronic design process technology integrated into its methods. The book is sharply written and well-illustrated.
Chronologische und theologiegeschichtliche Studien zu den Briefen des Ignatius von Antiochien
Author: Thomas Lechner
This volume discusses the authenticity of the seven letters, handed down under the name of Ignatius of Antioch, and explores the wider theological context at the time of their composition. The author first examines the chronological foundations of current scholarly consensus, which on the whole favours an early second-century date for the composition of these letters, during the reign of the emperor Trajan (98-117). On the basis of his findings the author next addresses the question raised by the title of the volume: do some of the polemic passages in these letters specifically attack Valentinian gnosis? After a detailed discussion of chapters 16-20 of the Letter to the Ephesians it is shown that the Ignatian Star Hymn (Eph. 19) should be seen as a parody of Valentinian myth. The volume concludes with a study of the "Regula fidei" (Eph. 18,2).
The German version of this standard work has provided generations of engineers with a comprehensive source of reference and guidance, on which they can rely throughout their professional lives, and is due to appear in its 19th edition. Now, for the first time, the key sections of this authoritative work are available in English. While DIN standards are retained throughout, the ISO equivalents are given wherever possible. Each subject is discussed in detail and supported by numerous figures and tables, equipping students and practitioners with a concise yet detailed treatment of: Mechanics, Strength of Materials, Thermodynamics, Engineering Design, Hydraulic and Pneumatic Power Transmission, Components of Thermal Apparatus, Machine Dynamics and Components, Manufacturing Process and Systems. Simply a must.
