Is it possible to forecast economic crises?Economic researchers have been grappling with this topic for generations. The outcome of all their efforts is a large number of to some extent contradictory theories. Regarding the economy as a living - pulsating - system, which organises itself and is in constant interaction with its environment, provides extensive insights and forms the basis for this book. The author Peter Meier presents a system that enables demand for capital goods to be forecast quite reliably up to eighteen months into the future, based on global economic indicators. In addition, the author establishes ten assumptions for economic forecasting that can be checked periodically. They can be used to gauge the approximate timing of an impending global economic crisis by more than a year in advance.

The book brings together the detailed knowledge of structure and morphology of the main classes of polymers, including commodities as well as special polymers, with explanation of the mechanical properties, processes, and mechanisms on macroscopic, microscopic, and nanoscopic scales. Description, explanation, and theoretical interpretation of all of the micro- and nanoscopic processes and mechanisms in different polymers constitute the central part the book. Thus, it offers a key for a better understanding of structure-property correlations of nearly all polymers of interest in industrial applications. A central aim of the book is to show how, by changing the morphology, microprocesses and, finally, the mechanical properties can be improved. There is no other book available on the market which is focused on micromechanical processes of polymers and their role to improve the properties of polymeric materials.

The manufacturing process for preparing very thin polymer products has developed into what is arguably the largest outlet for synthetic polymers. The central theme of this volume is the developments in process hardware and operating techniques that permit increasingly high production rates, optimum property development, unusual degrees of molecular orientation, and the coextrusion of multi-layer, multi-component film and sheet. The strong relationships and the interdependence of these developments on the achievements in polymer design, such as rheology and mechanical and optical properties, are also discussed.Contents:· Film Processing Overview and Introductory Rheology· Flat Die Analysis· Spiral Die Analysis· Die Control System of Film Thickness Distribution· Kinematics, Dynamics and Physical Properties of Blown Film· Bubble Instability: Experimental Evaluation· Optical Properties and Structural Characteristics of Tubular Film· Theoretical Analysis of Film Deformation Behavior in Casting· Analysis of Draw Resonance Instability in the Film Casting Process· Multilayer Films· Biaxially Oriented Films· Influence of Processing Conditions on Structure and Physical Properties of Biaxially Stretched Engineering Thermoplastics· Theoretical Analysis of Tentering Process· Double Bubble Tubular Film Process System and Theoretical Analysis of Stress Development and Scale-up Rule.

Plastics manufacturing is a highly interdisciplinary endeavor requiring knowledge related to materials science, physics, engineering, and management. Because of this diversity, the plastics process engineer interacts with many stakeholders including customers, designers, materials suppliers, machine builders, mold/die suppliers, systems integrators, operators, quality engineers, managers, and others. With so many stakeholders involved, it isn't surprising that many plastics manufacturing processes are not precisely engineered systems. The resulting processes can be poorly designed, requiring too much investment to achieve too little productivity.This book was written to educate and support plastics processing engineers, but is also highly useful to others involved with plastics manufacturing who are performing process development, research, and even machinery design. A manufacturing systems engineering approach was used to provide guidance about plastics manufacturing as an integrated system with broadly applicable analysis of the underlying subsystems.
