K.J. Ives Professor of Public Health Engineering University College London The aggregation of small particles in liquids, to form flocs which are large enough to settle, or to be filtered, is a common operation in industrial processes, and water and wastewater treatment. This aggregation, given the general title flliocculation in this book, may be brought about by the addition of chemicals to reduce the stability of the original suspension, by neutralising electrical forces of repulsion, by the addition of chemicals (polymers) to link particles by bridging action, by the addition of chemicals which form particles to increase collision proba bilities, and by the input of energy leading to hydrodynamically induced collisions. The particles undergoing flocculation may range from colloidal in the nanometer size range, through micro scopic (micron) size, up to visible particles in the millimeter size range; that is a total size range of six orders of magnitude. Consequently the colloid chemist and the hydrodynamicist are both concerned with the interactions that take place, and to them the engineer must turn, to obtain the fundamental information ne cessary for the process design and its associated hardware."

For many years production management has no longer been confined to individual production facilities. Intensive cooperation with suppliers has become an integral part of production management. In recent years two further developments have gained ground. On the one hand enterprises have been specialising and concentrating on their core competencies with outsourcing as a consequence, on the other hand globalization has intensified the range of choice among suppliers. Increased dependence on suppliers called for new forms of cooperative ventures. Strategic and legal issues had to be considered and production management had to include sophisticated logistic chain management. These developments have led to the concept of Extended Enterprise'. Among many other topics, this book discusses: co-operation between companies; supply chain management; agile and virtual management; integration of the logistic chain; and production and logistical strategies. The book comprises the proceedings of the Working Conference on Organizing the Extended Enterprise, sponsored by the International Federation for Information Processing (IFIP), which was held in Ascona, Switzerland in September 1997. It will be of great importance to researchers, managers and consultants in production, logistics and information and other areas of organizational development.

If a Writer would know how to behave himself with relation to Posterity; let him consider in old Books, what he finds, that he is glad to know; and what Omissions he most laments. Jonathan Swift This book emerges from a long story of teaching. I taught chemical engineering thermodynamics for about ten years at the University of Naples in the 1960s, and I still remember the awkwardness that I felt about any textbook I chose to consider-all of them seemed to be vague at best, and the standard of logical rigor seemed immensely inferior to what I could find in books on such other of the students in my first class subjects as calculus and fluid mechanics. One (who is now Prof. F. Gioia of the University of Naples) once asked me a question which I have used here as Example 4. 2-more than 20 years have gone by, and I am still waiting for a more intelligent question from one of my students. At the time, that question compelled me to answer in a way I didn't like, namely "I'll think about it, and I hope I'll have the answer by the next time we meet. " I didn't have it that soon, though I did manage to have it before the end of the course.

In important branches of manufacturing industries, especially those producing chemicals, polymers, semiconductors, ceramics, metals and alloys, analytical process control is already an integral part of the company. Far reaching decisions with respect to quality, ecology and economy are based on the respective analytical data. The goal of this practice-oriented book is to introduce chemists, engineers and technicians to the strategies, techniques and efficiency of modern process analytical chemistry. The author is especially aiming at those professionals in small and medium enterprises who have to carry out process control tasks in a "solo-run".

Nanostructuring of materials is a task at the heart of many modern disciplines in mechanical engineering, as well as optics, electronics, and the life sciences. This book includes an introduction to the relevant nonlinear optical processes associated with very short laser pulses for the generation of structures far below the classical optical diffraction limit of about 200 nanometers as well as coverage of state-of-the-art technical and biomedical applications. These applications include silicon and glass wafer processing, production of nanowires, laser transfection and cell reprogramming, optical cleaning, surface treatments of implants, nanowires, 3D nanoprinting, STED lithography, friction modification, and integrated optics. The book highlights also the use of modern femtosecond laser microscopes and nanoscopes as novel nanoprocessing tools.

The 1990s have seen many large-scale efforts to transform companies into more agile and efficient global enterprises. An important lesson from the efforts in computer-integrated manufacturing and other businesses has been that enterpriseslike any other system - need to be properly designed and that methods to do this should become widely available and publicised. Architectures for Enterprise Integration describes the latest methods to guide enterprises and consultants, managers and technical personnel through a complete life-cycle of enterprise development. This book is based on the findings of the IFIP/IFAC Task Force and presents a state-of-the-art review of enterprise architecture, including analysis and comparison of the three major architectural frameworks and methodologies; identification of the strengths and weaknesses of each methodology to enable users to select the approach which best suits their needs; a roadmap for the development of more complete methodologies by using existing ones. This book is essential reading for all practising engineers and researchers in manufacturing and engineering management and will be of special interest to those involved in CIM and enterprise modelling and integration.

This book is intended to address both the quantitative and qualitative issues of programmable controllers for factory automation. It is helpful for both the newcomer to the field and the experienced control engineer requiring a fresh perspective.

The use of coal is required to help satisfy the world's energy needs. Yet coal is a difficult fossil fuel to consume efficiently and cleanly. We believe that its clean and efficient use can be increased through improved technology based on a thorough understanding of fundamental physical and chemical processes that occur during consumption. The principal objective of this book is to provide a current summary of this technology. The past technology for describing and analyzing coal furnaces and combus tors has relied largely on empirical inputs for the complex flow and chemical reactions that occur while more formally treating the heat-transfer effects. GrOWing concern over control of combustion-generated air pollutants revealed a lack of understanding of the relevant fundamental physical and chemical mechanisms. Recent technical advances in computer speed and storage capacity, and in numerical prediction of recirculating turbulent flows, two-phase flows, and flows with chemical reaction have opened new opportunities for describing and modeling such complex combustion systems in greater detail. We believe that most of the requisite component models to permit a more fundamental description of coal combustion processes are available. At the same time there is worldwide interest in the use of coal, and progress in modeling of coal reaction processes has been steady."

This is a state-of-the-art guide to SMT with fine pitch components intended for professionals in electronics manufacturing. The overriding objective is to equip manufacturing people in the electronics industry with a better understanding of the manufacturing processes involved.

One hundred years ago, in September 1888, Professor Lewis Mills Norton (1855-1893) of the Chemistry Department of the Massachusetts Institute of Technology introduced to the curriculum a course on industrial chemical practice. This was the first structured course in chemical engineer ing taught in a University. Ten years later, Norton's successor Frank H. Thorpe published the first textbook in chemical engineering, entitled "Outlines of Industrial Chemistry." Over the years, chemical engineering developed from a simple industrial chemical analysis of processes into a mature field. The volume presented here includes most of the commissioned and contributed papers presented at the American Chemical Society Symposium celebrating the centenary of chemical engineering. The contributions are presented in a logical way, starting first with the history of chemical engineering, followed by analyses of various fields of chemical engineering and concluding with the history of various U.S. and European Departments of Chemical Engineering. I wish to thank the authors of the contributions/chapters of this volume for their enthusiastic response to my idea of publishing this volume and Dr. Gianni Astarita of the University of Naples, Italy, for his encouragement during the initial stages of this project."

From its inception in 1983, ESPRIT (the European Strategic Programme for Research and Development in Information Technology) has aimed at improving the competitiveness of European industry and providing it with the technology needed for the 1990s. Esprit Project 623, on which most of the work presented in this book is based, was one of the key projects in the ESPRIT area, Computer Integrated Manufacturing (CIM). From its beginnings in 1985, it brought together a team of researchers from industry, research institutes and universities to explore and develop a critical stream of advanced manufacturing technology that would be timely and mature for industrial exploitation in a five year time frame. The synergy of cross border collaboration between technology users and vendors has led to results ranging from new and improved products to training courses given at universities. The subject of Esprit Project 623 was the integration of robots into manufacturing environments. Robots are a vital element in flexible automation and can contribute substantially to manufacturing efficiency. The project had two main themes, off-line programming and robot system planning. Off-line programming enlarges the application area of robots and opens up new possibilities in domains such as laser cutting, and other hazardous operations. Reported benefits obtained from off-line program ming include: - significant cost reductions because re-programming eliminates robot down-time; - faster production cycles, in some cases time-savings of up to 85% are reported; - the optimal engineering of products with improved quality."

This book contains a selection of papers presented at APME '99 ( Third International Symposium on Advanced Polymers via Macromolecular Engineering --- Colonial Williamsburg, VA, USA, July/August 1999).
The book focuses on the synthesis of targeted polymers with specific properties using macromolecular architecture. Various controlled polymerization techniques such as ionic, metathesis and recently developed 'living'/controlled polymerization and some of their combinations are covered.
Polymers with different topologies such as block and graft copolymers, hyper branched polymers, heteroarm polymers, dentrimers, segmented networks and supramolecular systems are presented with emphasis on the special characteristics that influence their amphiphilic, liquid crystalline, complexation, thermo- and photosensitive and catalytic properties. The uses of such macromolecular structures in various fields such as surface modifiers, catalysts and coating and biomedical applications are also discussed.

This monograph aims to give a comprehensive and detailed review of general results, which have been obtained in a special segment of the design and manufacture of pressure-sensitive products, known as formulation. For manufacturers of pressure-sensitive products and product components, formulation probably includes the main part of their proprietary know-how. The scientific basis of formulation, explaining the reasons behind certain mixing and processing technologies, is doubtless more important than a collection of compositional data and technical parameters. This volume collects technical and scientific materials concerning the most important theoretical and practical aspects of the formulation of pressure-sensitive adhesives.
Based on the author's industrial and scientific experience, this treatise constitutes a theoretical and practical state-of-the-art monograph on the formulation of pressure-sensitive products. It is a practical guide for those who want to study, manufacture or use pressure sensitive products or their components, as well as for suppliers of adhesives, elastomers, plastics and additives, or manufacturing equipment.
This book will be of value and interest to production and manufacturing managers, production engineers, materials scientists, chemists and new product specialists involved in the production or application of pressure-sensitive products.

This book is a collection of papers presented at the 7th ISPE International Conference on Concurrent Engineering (CE): Research and Applications. The papers deal with different topics providing information on information modelling, CE in virtual environment, and standards in CE.

About five to six years ago, the words 'packaging and manufacturing' started to be used together to emphasize that we have to make not only a few but thousands or even millions of packages which meet functional requirements. The aim of this book is to provide the much needed reviews and in-depth discussions on the advanced topics surrounding packaging and manufacturing. The first chapter gives a comprehensive review of manufacturing chal lenges in electronic packaging based on trends predicted by different resources. Almost all the functional specifications have already been met by technologies demonstrated in laboratories. However, it would take tremendous efforts to implement these technologies for mass production or flexible manufacturing. The topics crucial to this implementation are discussed in the following chapters: Chapter 2: Challenges in solder assembly technologies; Chapter 3: Testing and characterization; Chapter 4: Design for manufacture and assembly of electronic packages; Chapter 5: Process modeling, optimization and control in electronics manufacturing; and Chapter 6: Integrated manufacturing system for printed circuit board assembly. The electronics-based products are very competitive and becoming more and more application-specific. Their packages should fulfill cost, speed, power, weight, size, reliability and time-to-market requirements. More importantly, the packages should be manufacturable in mass or flexible production lines. These chapters are excellent references for professionals who need to meet the challenge through design and manufacturing improvements. This book will also introduce students to the critical issues for competitive design and manufacturing in electronic packaging."

The separation of finely-divided solids from liquids constitutes an important stage in many industrial processes. Separation of mixtures ranging from highly concentrated slurries to slightly turbid liquids must be effected in circumstances where the solids, liquid or both phases may have value. Separations may be achieved by use of a membrane or filter medium which, positioned in the path of a flowing suspension, will allow passage of the fluid whilst retaining solids on the surface or within the medium. Alternatively the two phases may be separated by sedimentation processes involving gravitational or centrifugal force. In either mode, separation difficulties are sometimes experienced with the result that solid-liquid separation is often a bottleneck in commercial plants. Operational difficulties and plant failures are associated with the random nature of the particles being separated; variations in size, shape, states of aggregation, compressibility, etc. , produce a wide range of problems. Plugging of the filter medium or the collapse of the solids under applied stress lead to slow flowrates of liquid. The colloidal nature of some precipitates makes separation by settling virtually impossible without the use of chemical agents to enhance the size of basic units and to reduce repulsive surface forces. Unit operations such as filtration, comminution, etc. , involve a seemingly bewildering array of machines which makes plant selection a difficult step and reflects the uncer tainties attaching to operations involving the solid )hase. Many types of pressure, vacuum and centrifugal filter are available.
