Energy in Plastics Technology provides, unlike any other book, the necessary fundamentals for dealing with thermotechnical issues in the processing of plastics, leading to efficient, robust, reliable, economical, and environmentally friendly processes for high-quality products. The following four areas are addressed: - Methodical application of the essential fundamentals to practical problems. The focus is on the formulation of energy balances.- Special emphasis is placed on the understanding of the first and second laws of thermodynamics, with their manifold implications.- Access to key advanced technical literature, which can be highly theoretical, and forms the basis for advanced simulation methods, is provided.- Analytical approaches for modeling processes (as opposed to numerical simulation methods) are covered, so that the influence of the essential process parameters can be better recognized, and correct results in terms of order of magnitude are obtained with reasonable effort. These simplified considerations provide a valuable support for the preparation of experiments and numerical simulations and their critical evaluation. The fundamentals provided are applied - in exemplary calculation examples - to problems relevant to practice in the most important processing and forming methods. The book is aimed at engineers and students working in plastics technology as well as technicians and plastics technologists.

Systeme zur optischen Übertragung in Glasfaserkabeln sind im Nachrichten-Weitverkehr bereits heute wirtschaftlicher als entsprechende Kupferkabelsysteme. Hier kommen die beiden großen Vorteile der optischen Übertragung in Glasfasern, nämlich die geringe Dämpfung und die große Bandbreite, voll zum Tragen. Die Möglichkeit einer Breitbandkommunikation mit Integration der verschiedensten Dienste auf der Basis von Glasfaser-Teilnehmeranschlußleitungen wird seit einer Reihe von Jahren intensiv untersucht. Darüber hinaus werden weltweit große Anstrengungen unternommen, durch Fortschritte in den optischen Komponenten, der Kabel- und Verbindungstechnik und insbesondere durch den Einsatz der Mikroelektronik und integrierten Optik Teilnehmeranschlüsse in Glasfasertechnik auch für Schmalbanddienste, also z.B. für Fernsprechen, genauso wirtschaftlich zu machen wie die herkömmlichen Anschlüsse in Kupfertechnik. Ziel des Kongresse war es, die im In- und Ausland beschrittenen Wege zu wirtschaftlichen Teilnehmeranschlüssen in Glasfasertechnik aufzuzeigen und damit einen Beitrag zur baldigen Einführung dieser zukunftsorientierten Technik zu leisten.

"Ultrashort Laser Pulses" aims to provide an up-to-date review of the state of the art in different generation processes for ultrashort laser pulses. In addition, extensive applications in a wide range of fields - in physics, engineering, chemistry, and biology - are discussed: the generation of picosecond and femtosecond laser pulses; nonlinear wave interactions; new investigations in solid-state physics; recent progress in optoelectronics; advances in coherent material excitations; ultrafast vibrational lifetimes and energy redistribution in liquids; new observations of chemical reactions in the liquid state; the primary processes of important biological systems. This book should be useful for scientists and engineers who want to know what is going on in this rapidly advancing field. It should also interest graduate students and others who seek an introduction to laser pulses.
