Twentyfour years have gone by since the publication of K. Lohner and H. Muller's comprehen sive work "Gemischbildung und Verbrennung im Ottomotor" in 1967 1.1]' Naturally, the field of mixture formation and combustion in the spark-ignition engine has wit nessed great technological advances and many new findings in the intervening years, so that the time seemed ripe for presenting a summary of recent research and developments. There fore, I gladly took up the suggestion of the editors of this series of books, Professor Dr. H. List and Professor Dr. A. Pischinger, to write a book summarizing the present state of the art. A center of activity of the Institute of Internal-Combustion Engines and Automotive Engineering at the Vienna Technical University, which I am heading, is the field of mixture formation -there fore, many new results that have been achieved in this area in collaboration with the respective industry have been included in this volume. The basic principles of combustion are discussed only to that extent which seemect necessary for an understanding of the effects of mixture formation. The focal point of this volume is the mixture formation in spark-ignition engines, covering both the theory and actual design of the mixture formation units and appropriate intake manifolds. Also, the related measurement technology is explained in this work."

The main concern of this book is the application of infinite moment theory to the problem of controllability of one-di- mensional vibrating systems (like strings and beams) and heating processes. Distributed as well as boundary control is considered. In the case of vibrating systems trigonometric moment pro- blems are to be investigated which is done on the basis of an abstract moment theory in Hilbert spaces. Equivalently, alsothe theory of linear operator equations on Hilbert spa- ces ( partly with unbounded operators) is applied to the problem of controllability and time-minimal controllability. In the case of heating processes exponential moment problems are to be dealt with which is done on the basis of an ab- stract moment theory in Banach spaces. Time-minimal control- lability is also treated with the aid of the theory of line- aroperator equations on Banach spaces. Some advanced knowledge in functional analyis and on partial differential equations is preassumed for a fluent reader of the book, but parts of it are also readable with basic ma- thematical knowledge (for instance, the finite-dimensional part of the introduction).

The German R + D program "Solares Testzentrum Almeria" (SOTA) provided the scientific basis for the realization of advanced solar technologies including facility modifications, component tests and new lines of development. One of the working packages, WP 300, addressed the "Scientific Support" by the performance of preparatory studies, exploratory laboratory activities and qualified expertise. Universities, Research Institutes and Company R + D Entities in Germany were enabled to treat the following aspects: * Meteorological, system and cost investigations, * Development of important components as concentrator, receiver, storage, * Utilization of solar energy for process heat and chemical reactions. Besides the continued development of terminal concentrators, the studies concentrated in 1991 on the development of solar chemistry processes. The reports of the activities were finalized recently and collected in the present volume. The final reports were printed as received. The achieved results and the views expressed within the reports were under the responsibility of the authors. As organizers of these solar thermal activities and as editors of the corresponding final reports, we would like to thank BMFT and KFA-BEO for the farsighted funding (grant no. 0328823A) and the research groups for their engagement and consultations. We would also like to thank Ms S. Preusser and Ms U. Rachow, who among many others contributed to the realization of this volume.

An eminent early preservationist, John Crawley was able to amass an enviable photographic archive of steam traction engines and road rollers in their working days, of which this Aveling & Porter selection formed just a part. Organiser of over eighty steam rallies, John saved up to thirty steam traction engines for preservation from the mid-1950s to the early 1960s, at a time when they were considered not much more than worthless scrap. Indeed, he became the first owner of no fewer than twenty-two of them. Utilising this incredible and unique collection of images, most of which are previously unpublished, Colin Tyson tells the story of this important manufacturer and iconic British brand.

This book deals with two key aspects of the history of steam engines, a cornerstone of the Industrial Revolution, specifically the road that led to its discovery and the process of diffusion of the early steam engines. The first part of the volume outlines the technological and scientific developments which took place between the 16th and 18th centuries, proving critical for the invention of this strategic technology. The most important question addressed is why did England come up with this innovation first as opposed to other countries (e.g., France, Italy), which were more advanced in terms of knowledge pertinent to it. The second part of the volume traces the process of diffusion of the early steam engines, the Newcomen model, through to 1773, the year prior to the first commercial application of the second generation of steam engines (the Watt model). The process of diffusion is quantified on the basis of a novel method before proceeding with a discussion of the main determinants of this process. Kitsikopoulos pulls together a large amount of relevant evidence found in primary sources and more technically oriented literature which is often ignored by economic historians. This book will be of interest to economic historians and historians of technology.

Lean burning of premixed gases is considered to be a promising combustion technology for future clean and highly efficient gas turbine combustors. Yet researchers face several challenges in dealing with premixed turbulent combustion, from its nonlinear multiscale nature and the impact of local phenomena to the multitude of competing models. Filling a gap in the literature, Fundamentals of Premixed Turbulent Combustion introduces the state of the art of premixed turbulent combustion in an accessible manner for newcomers and experienced researchers alike. To more deeply consider current research issues, the book focuses on the physical mechanisms and phenomenology of premixed flames, with a brief discussion of recent advances in partially premixed turbulent combustion. It begins with a summary of the relevant knowledge needed from disciplines such as thermodynamics, chemical kinetics, molecular transport processes, and fluid dynamics. The book then presents experimental data on the general appearance of premixed turbulent flames and details the physical mechanisms that could affect the flame behavior. It also examines the physical and numerical models for predicting the key features of premixed turbulent combustion. Emphasizing critical analysis, the book compares competing concepts and viewpoints with one another and with the available experimental data, outlining the advantages and disadvantages of each approach. In addition, it discusses recent advances and highlights unresolved issues. Written by a leading expert in the field, this book provides a valuable overview of the physics of premixed turbulent combustion. Combining simplicity and topicality, it helps researchers orient themselves in the contemporary literature and guides them in selecting the best research tools for their work.

In The Last Ten Years, author Brian J. Dickson presents stunning colour photographs from the collections of three enthusiasts of the Seafield Railway Club in north London. Meeting regularly at New Southgate station to record the steam-handled traffic, their focus was initially on all things connected with the former London and North Eastern Railway, but as steam traction became restricted to smaller and smaller areas of operation, regular visits were made further afield, to the north-east of England, Scotland and the former London Midland and Scottish Railway sheds and lines. This record of steam locomotion in its final years of mainline usage, from 1959 to 1968, is sure to enhance any steam railway enthusiast's library.
