Metrology is the study of measurement. It includes all theoretical and practical aspects of measurement and may be divided into three subfields:

Scientific or fundamental metrology concerns the establishment of measurement units, unit systems, development of new measurement methods, realization of measurement standards and the transfer of traceability from these standards to users in society.

This handbook contains articles dealing with general topics of measurement and articles on particular subjects in mechanics and acoustics, electricity, optics, temperature, time and frequency, chemistry, medicine and particles. The contributions of the first part are sumamrized as follows.IntroductionUnitsFundamental ConstantsFundamentals of Materials Measurement and TestingMeasurement of Mass DesnityMeasurement and Instrumentation of FlowUltrasonicsMeasurement of Basic Electromagnetic QuantitiesQuantum Electrical StandardsMetrology of Time and FrequencyTemperature MeasurementMetrology in Medicine

The connection between a quantum behavior of the structure elements of a substance and the parameters that determine the macroscopic behavior of materials has a major influence on the properties exhibited by different solids. Although quantum theory and engineering should complement each other, this is not always the case. This book aims to demonstrate how the properties of materials can be derived and predicted proceeding from the features of their structural elements, generally electrons. In a sense, electronic structure forms the glue holding solids as whole, and it is central in determining structural, mechanical, chemical, electrical, magnetic and vibrational properties. The main part of the book is devoted an overview of the fundamentals of the density functional theory and its applications to computational solid state physics and chemistry. The author shows in detail the technique of construction of models and the methods of their computer simulation. He considers physical and chemical fundamentals of interatomic bonding in solids and analyzes the predicted theoretical outcome in comparison with experimental data. This is applying the first-principle simulation methods so as to predict the properties of transition metals, semiconductors, oxides, solid solutions, molecular and ionic crystals. Unique in presenting are novel theories of creep and fatigue that help to anticipate - and prevent - possible fatal material failures. As a result, users gain the knowledge and tools to simulate material properties and to design materials with desired characteristics. Due to the interdisciplinary nature of the book, it is suitable for a variety of markets from students and lectures to engineers and researchers.

Technische Mechanik in kompakter Form wird in diesem Lehrbuch in den Hauptkapiteln Statik, Festigkeitslehre, Kinematik, Kinetik sowie Numerische Methoden behandelt. Jedes Unterkapitel schliesst mit Ubungsbeispielen, praxisbezogenen Hinweisen und Tipps ab, jedes Hauptkapitel mit einer Zusammenfassung. In Ingenieurburos und Entwicklungsabteilungen der Industrie sind numerische Methoden der Festkorpermechanik, verbunden mit Simulations- und Konstruktionssoftware und der anschliessenden Visualisierungen zur Beanspruchungs- und Formanderungsermittlung ein unerlassliches Handwerkszeug. Hier schafft das Kapitel Numerische Methoden der Festkorpermechanik die Verbindung zwischen den Grundlagen der Technischen Mechanik und der praktischen Umsetzung. Der Inhalt des vorliegenden Lehrbuches ist vorwiegend auf die Anwender der Technischen Mechanik und ihrer Methoden zugeschnitten und richtet sich damit insbesondere an Ingenieurstudenten des Maschinenbaus, der Werkstoffwissenschaften, der Elektrotechnik und des Wirtschaftsingenieurwesens. Diese werden vor allem befahigt, an Hand soliden Grundwissens die Maxime aller Bauteilbewertung so genau wie notig, so einfach wie moglich zu befolgen.

The only book to provide a complete survey -- from the crystallographic fundamentals right up to recent high-tech applications in aerospace technology.
Following a general introduction to the topic, the authors go on to cover the crystal chemistry of mullite and related phases, as well as its basic properties, phase equilibria and stability. One whole section is devoted to the synthesis and processing of mullite ceramics, while later ones cover mullite coatings, fibers and matrix composites.
For materials scientists, solid state chemists and physicists, crystallographers and mineralogists.
