Die in dem Sammelband «Empfehlungen des Arbeitskreises 1.4 Baugrunddynamik» der Deutschen Gesellschaft für Geotechnik e.V. (DGGT) zusammengefassten Empfehlungen haben das Ziel, das Vorgehen bei baugrunddynamischen Aufgaben zu vereinheitlichen. Ferner geben Sie Hinweise, wie durch angemessene baugrunddynamische Untersuchungen die Beeinträchtigung von Einrichtungen, Schäden an Bauwerken und Anlagen sowie störende Umwelteinwirkungen auf Menschen und Geräte vermieden werden können. Die vorliegenden Empfehlungen stellen den neuesten Stand von Wissenschaft und Technik auf dem Gebiet der Baugrunddynamik dar. Sie beruhen auf gesicherten Erkenntnissen, die einen empirischen Nachweis einschließen, d. h. es liegen für diese Empfehlungen auch praktische Erprobungen vor. Sie sind daher Bestandteil der ?allgemein anerkannten Regeln der Technik?. Für die vorliegende zweite Ausgabe wurden die Empfehlungen erneut umfangreich überarbeitet und um zwei Teile ergänzt.

Der Umgang mit vorhandener Bausubstanz gehört zu den täglichen Aufgaben für Bauingenieure und Architekten. Das vorliegende Buch vermittelt die notwendigen Kenntnisse der verschiedenen Methoden der Zustandserfassung und Bewertung von Bauteilen und Tragwerk sowie der Planung von Instandsetzungs- und Ertüchtigungsmaßnahmen. Ein Überblick über die Entwicklung der Bemessungsregeln und Materialkennwerte im Stahlbetonbau hilft bei der Auswertung von Bestandsunterlagen. Zahlreiche anschauliche Beispiele machen das Buch zu einem unverzichtbaren Leitfaden für die Planung und zu einem wertvollen Begleiter für das Studium. Für die zweite Auflage wurden die Inhalte mit Bezug zu den gültigen technischen Regelwerken vollständig aktualisiert. Darüber hinaus wurden einige Teile zum besseren Verständnis vollständig überarbeitet und neue Abschnitte aufgenommen.

The purpose of this monograph is to provide a thorough outlook on the topic related to the synthesis and characterization of original macromolecular materials derived from plant oils, an important part of the broader steadily growing discipline of polymers from renewable resources. The interest in vegetable oils as sources of biodiesel and materials has witnessed a remarkable growth of scientific and industrial interest since the beginning of the third millennium responding to the pressing drive to implement sustainability in the energy and materials sectors. The book highlights the most relevant strategies being pursued to elaborate polymers derived from a variety of common oils, by direct activation or through chemical modifications yielding novel monomers. Because glycerol is the main byproduct of biodiesel production, it is treated here as the other logical source of macromolecular synthesis. Each of the different approaches is illustrated by an introductory layout of the underlying chemical mechanisms, followed by examples of notable achievements in terms of the properties and potential applications of the ensuing materials, which span a wide range of structures and performances. In particular, original pathways involving click-chemistry reactions as thiol-ene and Diels-Alder couplings and metathesis polymerizations are discussed and shown to reflect the involvement of a growing number of research programs worldwide. It is important to underline that the book is not a scientific review covering the details of all relevant literature, but instead a reasoned and well-documented presentation of the state-of-the-art aimed at professionals in the field of polymer science, as well as at both undergraduate and graduate students and, more generally at chemists interested in the rational exploitation of renewable resources.

3D industrial printing has become mainstream in manufacturing. This unique book is the first to focus on polymers as the printing material. The scientific literature with respect to 3D printing is collated in this monograph. The book opens with a chapter on foundational issues such and presents a broad overview of 3D printing procedures and the materials used therein. In particular, the methods of 3d printing are discussed and the polymers and composites used for 3d printing are detailed. The book details the main fields of applications areas which include electric and magnetic uses, medical applications, and pharmaceutical applications. Electric and magnetic uses include electronic materials, actuators, piezoelectric materials, antennas, batteries and fuel cells. Medical applications are organ manufacturing, bone repair materials, drug-eluting coronary stents, and dental applications. The pharmaceutical applications are composite tablets, transdermal drug delivery, and patient-specific liquid capsules. A special chapter deals with the growing aircraft and automotive uses for 3D printing, such as with manufacturing of aircraft parts and aircraft cabins. In the field of cars, 3D printing is gaining importance for automotive parts (brake components, drives), for the fabrication of automotive repair systems, and even 3D printed vehicles.

Covers all the noise and vibration issues relating to the automotive body Features a thorough set of tables, illustrations, photographs, and examples Introduces automotive body structure and noise and vibration problems Pulls together the diverse topics of body structure, sound package, sound quality, squeak and rattle, and target setting Noise and Vibration Control of Automotive Body is a valuable reference for engineers, designers, researchers, and graduate students in the fields of automotive body design and NVH.

An essential guide for recognizing and responding to normalization of deviance to help organizations improve their process safety performance This book provides an introduction and offers approaches for finding and addressing normalization of deviation both in operational and organizational activities. It addresses the initial and long-term effects of normalization of deviations as seen in reduced efficiencies, reduced product quality, extended batch run time, and near miss process safety incidents which can lead to loss of containment of hazardous materials and energies. Recognizing and Responding to Normalization of Deviance addresses how to recognize and respond to the normalization of deviation that can, and almost certainly will, occur in any ongoing operations that involves humans. The book’s primary focus is on reducing the incidence of normalization of deviation and the associated increased risk exposure due to its effects when operating chemical or petrochemical manufacturing facilities. It contains an introduction to the concept and offers approaches for finding and addressing normalization of deviation when it presents itself in both operational and organizational activities. Contains guidance to assist facilities in recognizing and addressing the phenomenon of normalization of deviation Provides techniques for addressing normalized deviations and techniques to eliminate waste in all manufacturing processes Describes methods for identifying normalized deviation as well as where to find deviations Includes techniques to reduce operational normalization of deviance and to reduce organizational normalization of deviance Aimed at process safety professionals and consultants applying process safety risk reduction efforts in manufacturing areas, Recognizing and Responding to Normalization of Deviance is an important book for any organization that has seen its process safety performance deteriorate over time.

Discusses the fundamental principles of the design and development of microwave satellite switches utilized in military, commercial, space, and terrestrial communication This book deals with important RF/microwave components such as switches and phase shifters, which are relevant to many RF/microwave applications.
