The text is based on a course on turbomachinery which the author has taught since year 2000 as a technical elective. Topics include; Energy Transfer in Turbomachines, Gas and Steam Turbines, and Hydraulic Turbines. New material on wind turbines, and three-dimensional effects in axial turbomachines is included. The level is kept as such that students can smoothly move from a study of the most successful books in thermodynamics, fluid dynamics, and heat transfer to the subject of turbomachinery. The chapters are organized in such a way that the more difficult material is left to the later sections of each chapter. Thus, depending on the level of the students, instructors can tailor their course by omitting some sections. Key features: Combines theory and applications to show how gas turbines, pumps and compressor function Allows for a smooth transition from the study of thermodynamics, fluid dynamics, and heat transfer to the subject of turbomachinery for students and professionals Relates turbomachinery to new areas such as wind power and three-dimensional effects in axial turbomachines Provides information on several types of turbomachinery rather than concentrating specifically on one type such as centrifugal compressors

Tribologie, Korrosion, Konstruktion und Werkstofftechnik sind Wissensbereiche, die sich zunachst parallel entwickelt haben. Das gleiche gilt fur die verschiedenen Verfahren der Oberflachentechnik. Heute wird es zunehmend wichtiger, interdisziplinare Ansatze zu finden, um die Problemstellungen der Zukunft, wie z.B. Umweltschutz oder Ressourcenschonung, gemeinsam zu losen. Das Buch verfolgt den Ansatz, diese Wissensbereiche zu verknupfen. Es beginnt mit einer Beschreibung technischer Oberflachen hinsichtlich chemischer Zusammensetzung und geometrischer Struktur. Technische Systeme des Maschinenbaus (Bauteile oder Werkzeuge) sind Umgebungseinflussen (Druck, Chemie, Temperatur) ausgesetzt, die zu Oberflachenschaden durch Verschlei? und Korrosion fuhren konnen. Um Oberflachen davor zu schutzen, mussen die Grundlagen der Tribologie (Lehre von Reibung und Verschlei?) und Korrosion zunachst verstanden sein, weshalb die wichtigsten Begriffe und Definitionen zu Beginn des Buches beschrieben werden. Schwerpunkt des Buches ist die Behandlung der Verfahren der Oberflachentechnik, die im Maschinenbau Anwendung finden. Jedes Verfahren wird hinsichtlich Beschichtungsprozess, Anlagentechnik, Schichtwerkstoffen, typischen Schichtdicken, Beschichtungstemperaturen und Schichtwerkstoffen beschrieben und anhand von Anwendungsbeispielen vorgestellt. Wesentliches Element der Oberflachentechnik ist die Kombination unterschiedlicher Werkstoffe oder Werkstoffeigenschaften, um Volumen- und Oberflacheneigenschaften getrennt voneinander entsprechend der Anwendung optimieren zu konnen. Daher ist abschlie?end eine sehr kurze Einteilung wichtiger Werkstoffe gegeben (Metalle, Keramiken, Polymere). Die Kombination aus Tribologie, Korrosion, Verfahren der Oberflachentechnik und Werkstoffkunde ermoglicht eine strukturierte Herangehensweise bei der Auslegung von Oberflachen.

In der Lebensmittel-, der kosmetischen, pharmazeutischen und chemischen Industrie sowie in der Biotechnologie ist zum Schutz vor Kontamination ein hygienischer Produktionsprozess sehr wichtig. Sichere Qualitatsprodukte lassen sich nur mit Anlagen herstellen, die sich zuverlassig reinigen lassen. Deshalb spielt bei der Herstellung hochreiner Produkte «Hygienic Design» moderner Anlagen, Apparate, Komponenten und Prozessraume eine entscheidende Rolle. In allen Industriezweigen konnen dadurch erhebliche Kosten fur den Reinigungsaufwand und zur Reduzierung der Umweltbelastung eingespart werden. Das vorliegende Werk baut auf dem Buch Hygienische Produktionstechnologie auf und beschreibt die Komponenten und Bauteile, die fur die Konstruktion hygienegerechter Apparate und Anlagen benotigt werden. Es richtet sich besonders an Ingenieure im konstruktiven Bereich in der Lebensmittel-, Pharma- und Kosmetikindustrie, aber auch an Betriebsangehorige, die fur Qualitat, Risikoanalysen und Produktsicherheit bei der Produktherstellung verantwortlich sind.

Spannend wie ein Krimi: Big-Bang und Leben auf dem Mars Wie kam es dazu, dass sich unsere Erde allmahlich aus dem Nebel des Sonnensystems zu formen begann und was ist dran an der Theorie, dass das Leben in Form von Sporen direkt aus dem All zu uns auf die Erde transportiert wurde? Unsere bisherige Evolutionsgeschichte liest sich schon spannend wie ein Krimi. Und hier verraten international renommierte Wissenschaftler auch ihre Zukunftsvisionen, wie z. B. Professor Jesco von Puttkamer (ISS und NASA), der ergrundet, ob Leben auf dem Mars moglich ist. Wie nahrhaft war die Ursuppe? Ist das Leben aus einer uppigen und vor Nahrstoffen strotzenden Ursuppe entstanden, warum ist es so schwer, den Molekulbaukasten der Erde zu erforschen und kennen Sie schon das alteste uberlebende Urzeitrelikt? Hier bekommen Sie alle Antworten, die die Wissenschaft bislang erforscht hat, und machen sich mit Experten auf Spurensuche – unter anderem nach dem Stoff, aus dem die Gene sind. Wo sind sie alle? Auf der Suche nach au?erirdischem Leben >>Die Erde als die einzige bevolkerte Welt im All anzusehen, ist ebenso absurd wie die Behauptung, auf einem mit Hirse gesaten Feld sprie?e nur ein einziges Korn.<< Das schrieb ein Gelehrter im 4. Jahrhundert vor Christus. Doch auch heute noch steckt die Wissenschaft beim Erforschen au?erirdischen Lebens in den Kinderschuhen und fragt sich: wo sind sie alle? Vor noch nicht langer Zeit wurde bestatigt, dass es au?erhalb unseres Sonnensystems andere Welten gibt. Aber gibt es dort intelligente >>Nachbarn<

Electrostatic discharge (ESD) continues to impact semiconductor components and systems as technologies scale from micro- to nano-electronics. This book studies electrical overstress, ESD, and latchup from a whole-chip ESD design synthesis approach. It provides a clear insight into the integration of ESD protection networks from a generalist perspective, followed by examples in specific technologies, circuits, and chips. Uniquely both the semiconductor chip integration issues and floorplanning of ESD networks are covered from a ‘top-down' design approach. Look inside for extensive coverage on: integration of cores, power bussing, and signal pins in DRAM, SRAM, CMOS image processing chips, microprocessors, analog products, RF components and how the integration influences ESD design and integration architecturing of mixed voltage, mixed signal, to RF design for ESD analysis floorplanning for peripheral and core I/O designs, and the implications on ESD and latchup guard ring integration for both a ‘bottom-up' and ‘top-down' methodology addressing I/O guard rings, ESD guard rings, I/O to I/O, and I/O to core classification of ESD power clamps and ESD signal pin circuitry, and how to make the correct choice for a given semiconductor chip examples of ESD design for the state-of-the-art technologies discussed, including CMOS, BiCMOS, silicon on insulator (SOI), bipolar technology, high voltage CMOS (HVCMOS), RF CMOS, and smart power practical methods for the understanding of ESD circuit power distribution, ground rule development, internal bus distribution, current path analysis, quality metrics ESD: Design and Synthesis is a continuation of the author's series of books on ESD protection.

Water based heating systems are efficient, flexible, versatile and offer many advantages over other heating systems. These advantages (fast response, good controllability, efficient zonal heating and largely silent operation) all require that initial design, installation, commissioning and maintenance be carried out to a high standard by competent engineers. Heating Services in Buildings provides the reader with a detailed and thorough understanding of the principles and elements of heating buildings using modern water based heating systems. A key theme of the book is that there is little difference, in the approach to the design and engineering, between domestic and commercial installations. The author’s detailed but highly practical approach to the subject ensures there is sufficient information for students from both a craft background and those with more academic backgrounds to understand the material. This approach is complemented by straightforward, easy-to-use diagrams. Heating Services in Buildings supports a range of educational courses, including degree level building services engineering; NVQ Level 4 Higher Professional Diploma in Building Services Engineering; City & Guilds supplementary heating course and the Heating Design and Installation Course accredited by the European Registration Scheme (ERS).
