The LES-method is rapidly developing in many practical applications in engineering The mathematical background is presented here for the first time in book form by one of the leaders in the field
This book describes new algorithms and ideas for making effective decisions under constraints, including applications in control engineering, manufacturing (how to optimally determine the production level), econometrics (how to better predict stock market behavior), and environmental science and geosciences (how to combine data of different types). It also describes general algorithms and ideas that can be used in other application areas. The book presents extended versions of selected papers from the annual International Workshops on Constraint Programming and Decision Making (CoProd’XX) from 2013 to 2016. These workshops, held in the US (El Paso, Texas) and in Europe (Würzburg, Germany, and Uppsala, Sweden), have attracted researchers and practitioners from all over the world. It is of interest to practitioners who benefit from the new techniques, to researchers who want to extend the ideas from these papers to new application areas and/or further improve the corresponding algorithms, and to graduate students who want to learn more – in short, to anyone who wants to make more effective decisions under constraints.

With applications to climate, technology, and industry, the modeling and numerical simulation of turbulent flows are rich with history and modern relevance. The complexity of the problems that arise in the study of turbulence requires tools from various scientific disciplines, including mathematics, physics, engineering and computer science. Authored by two experts in the area with a long history of collaboration, this monograph provides a current, detailed look at several turbulence models from both the theoretical and numerical perspectives. The k-epsilon, large-eddy simulation and other models are rigorously derived and their performance is analyzed using benchmark simulations for real-world turbulent flows. Mathematical and Numerical Foundations of Turbulence Models and Applications is an ideal reference for students in applied mathematics and engineering, as well as researchers in mathematical and numerical fluid dynamics. It is also a valuable resource for advanced graduate students in fluid dynamics, engineers, physical oceanographers, meteorologists and climatologists.
The second edition of Extrusion is designed to aid operators, engineers, and managers in extrusion processing in quickly answering practical day-to-day questions. The first part of the book provides the fundamental principles, for operators and engineers, of polymeric materials extrusion processing in single and twin screw extruders. The next section covers advanced topics including troubleshooting, auxiliary equipment, and coextrusion for operators, engineers, and managers. The final part provides applications case studies in key areas for engineers such as compounding, blown film, extrusion blow molding, coating, foam, and reprocessing.

Fjords are deep, glacia11y carved estuaries that are pecu1iar to certain coast1ines, and have severa1 characteristics that dist inguish them from sha110wer embayments. At higher latitudes they indent the western coast1ines of Scandinavia, North and South America, and New Zea1and. They are a1so a common feature of much of the arctic coast1ine. The papers contained in this vo1ume were presented at a workshop funded by the NATO Advanced Studies Institute in Victoria, British Co1umbia. It may seem curious to the reader that this specia1 c1ass of estuaries shou1d have attracted an international gathering of oceanographers from severa1 different discip1ines. The reas on for this interest stems from both practica1 and scientific considerations. On the one hand, fjords are a feature common to the coast1ines of severa1 countries that depend heavi1y on the oceans for communication, fisheries and other resources. The impact of man's activities on these coasts has created a demand for new know1edge of the physica1, bio10gica1 and chemica1 aspects of fjords. Sometimes man's inf1uence on the ocean is intentiona1 as, for examp1e, in the artificia1 contro1 of ice cover; often it is the more insidious bui1d-up of toxic wastes that is of concern. These prob1ems are particu1ar1y acute where the conf1icting demands of fisheries, industria1 deve10pment and re creation meet in a sing1e fjord; and indeed, this is a common occurence a10ng severa1 of the fjords in Scandinavia and Canada.
