This book elucidates how Finite Element methods look like from the perspective of Green's functions, and shows new insights into the mathematical theory of Finite Elements. Practically, this new view on Finite Elements enables the reader to better assess solutions of standard programs and to find better model of a given problem.
The book systematically introduces the basic concepts how Finite Elements fulfill the strategy of Green's functions and how approximating of Green's functions. It discusses in detail the discretization error and shows that are coherent with the strategy of "goal oriented refinement." The book also gives much attention to the dependencies of FE solutions from the parameter set of the model."

It is with great pleasure that I offer my reflections on Professor Anthony N. Michel's retirement from the University of Notre Dame. I have known Tony since 1984 when he joined the University of Notre Dame's faculty as Chair of the Depart ment of Electrical Engineering. Tony has had a long and outstanding career. As a researcher, he has made im portant contributions in several areas of systems theory and control theory, espe cially stability analysis of large-scale dynamical systems. The numerous awards he received from the professional societies, particularly the Institute of Electrical and Electronics Engineers (IEEE), are a testament to his accomplishments in research. He received the IEEE Control Systems Society's Best Transactions Paper Award (1978), and the IEEE Circuits and Systems Society's Guillemin-Cauer Prize Paper Award (1984) and Myril B. Reed Outstanding Paper Award (1993), among others. In addition, he was a Fulbright Scholar (1992) and received the Alexander von Hum boldt Forschungspreis (Alexander von Humboldt Research Award for Senior U.S. Scientists) from the German government (1997). To date, he has written eight books and published over 150 archival journal papers. Tony is also an effective administrator who inspires high academic standards."

The time delays in controllers and actuators can either deteriorate or improve the dynamic performance of a controlled mechanical system. Thus, it is desirable to gain an insight into the effect of time delays on the dynamics of a practical system in its design phase. This monograph represents the recent advances in system modeling, analysis of stability, robust stability and bifurcation by using some new mathematical tools such as generalized Sturm criterion and Dixon's resultant elimination of polynomials. The theoretical results are demonstrated through a number of examples of active vehicle chassis, structure control, as well as the control of chaos of mechanical systems.

This volume is a compilation of contributions in applied mechanics, dealing with both solid and fluid mechanics. The contributions are based on material presented at the national mechanics congress held in the Netherlands during November 16--18, 1992. The scope of the volume covers both theoretical and applied issues, including the following themes: Experimental mechanics, how to use modern electronic equipment, optical techniques and software tools to measure strain, stress, displacements, forces, etc. in both fluids and solids. The analysis of localised effects on stiffness, strength and stability of structures, like dikes, bridges, roads, and all public works necessary to improve among other things the navigability of canals and rivers. The analysis of damage processes in concrete and fiber reinforced polymers and the quest to make such processes accessible by numerical computation. The analysis of localised effects on fluid flow, leading to more understanding of the origin of the different colours of musical tones and human speech, but also to more understanding of the pulsating flow of blood through complicated shaped arteries and drag reduction in turbulent flow through pipes or along walls, as a result of small sized surface grooves or the addition of a very small amount of polymer to liquids. The investigation of non-linearities in the behaviour of dynamic systems such as manipulators, railway vehicles, etc. Micromechanics and constitutive equations. In order to describe complex material behaviour understanding of momentum and heat transport on almost the molecular level is needed. This emphasizes the importance of micromechanics in relation to the ultimate strength of compositematerials, ranging from fiber reinforced plastics up to very high temperature resistant ceramics toughened by thin hairlike crystals of exceptional mechanical strength. Fluid-structure interactions, such as occur in non-rigid pipelines and artery systems.

Rigorous presentation of Mathematical Homogenization Theory is the subject of numerous publications. This book, however, is intended to fill the gap in the analytical and numerical performance of the corresponding asymptotic analysis of the static and dynamic behaviors of heterogenous systems. Numerous concrete applications to composite media, heterogeneous plates and shells are considered. A lot of details, numerical results for cell problem solutions, calculations of high-order terms of asymptotic expansions, boundary layer analysis etc., are included.

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 work treats structural and continuum mechanics in a unified and consistent manner.

All theoretical developments are presented both in the text and by means of an extensive set of figures. Text and figures complement each other, and this twofold presentation is also used in the examples. Volume 2 covers stresses and strains in simple elements subjected to extension, bending, shear and torsion. For elementary structures like trusses, beams and frames, displacements due to simple loads are obtained using both classical mathematical descriptions with differential equations and engineering methods like Williot diagrams for (simple) trusses and "forget-me-nots" and moment-area formulae for bending.

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.

Solidification and Crystallization Processing in Metals and Alloys

Hasse Fredriksson "KTH, Royal Institute of Technology, Stockholm, Sweden"

Ulla akerlind "University of Stockholm, Sweden"

Solidification or crystallization occurs when atoms are transformed from the disordered liquid state to the more ordered solid state, and is fundamental to metals processing. Conceived as a companion volume to the earlier works, "Materials Processing during Casting" (2006) and "Physics of Functional Materials" (2008), this book analyzes solidification and crystallization processes in depth.

Starting from the thermodynamic point of view, it gives a complete description, taking into account kinetics and mass transfer, down to the final structure. Importantly, the book shows the relationship between the theory and the experimental results. Topics covered include: Fundamentals of thermodynamics Properties of interfaces Nucleation Crystal growth - in vapours, liquids and melts Heat transport during solidification processes Solidification structures - faceted, dendritic, eutectic and peritectic Metallic glasses and amorphous alloy melts

"Solidification and Crystallization Processing in Metals and Alloys "features many solved examples in the text, and exercises (with answers) for students. Intended for Masters and PhD students as well as researchers in Materials Science, Engineering, Chemistry and Metallurgy, it is also a valuable resource for engineers in industry.

Micromechanics provides a link between the structure and the properties at different scales of observation. This book deals with micromechanical analysis of interfaces and interface layers and presents several modelling tools. These range from the rigorous method of asymptotic expansions to practical finite element simulations, suitable for this class of problems. The corresponding two parts of the book are self-contained, so they can be read separately.

This book presents thermodynamic data on oxides in the system MgO-FeO-Fe2O3-Al2O3-SiO2. These data are produced by a process of assessment that involves the integration of thermochemical (calorimetric) and phase equilibrium data. The latter have been selected from a number of publications in high-pressure research conducted at pressures and temperatures in the range of 1 bar to several Giga Pascals and 300 to 2500 K respectively. A unique feature of the database is that the assessment involves not only the thermodynamic data on pure end member species, but also the data on multicomponent solutions. Since the solution description follows the format used in the popular thermodynamic computational packages such as FACTSAGE, ChemSage and Thermocalc, the database is easy to incorporate in the currently used databases in these packages. The database is highly useful to those working in the field of metallurgy (e.g. slags) and ceramics. It is essential for all those who do thermodynamic modeling of the terrestrial planetary interiors.

Develop a healthier connection between worker and work with this practical introduction The United States Bureau of Labor Statistics estimates that 34% of all workdays lost each year are the result of work-related musculoskeletal disorders (WMSDs). These disorders result from a mismatch between a worker, their working conditions, and the task they perform. Improperly designed tasks or equipment, insufficient downtime between shifts or tasks, or even simple sitting position can all produce WMSDs. The key insights into preventing these disorders are produced by ergonomics, the scientific study of human bodies as they relate to objects, systems, and environments, especially work environments. Occupational Ergonomics: A Practical Approach aims to supply an ergonomic toolkit for creating healthier relationships between workers' bodies and their work. Beginning with a set of foundational ergonomic principles, it then details multiple assessment techniques in ways easily adapted to specific workplace situations. This balance of theory and practice has made Occupational Ergonomics an essential reference concerning human beings and the work they do. Readers of the second edition will also find: Up-to-date ergonomic research reflecting the latest clinical and workplace data. Entirely new chapters on Work Physiology, Total Worker Health, Return on Investment, and more. Major revisions to chapters on Elements of an Ergonomic Program, Workstation Design, Work-Related MSDs, How to Conduct an Assessments, and Office Ergonomics Detailed and updated case studies applying ergonomic assessment techniques to common workplace scenarios. Occupational Ergonomics is a must for workplace safety managers, safety coordinators, ergonomics program coordinators, facilities managers, and any professionals concerned with the work environment, and worker health and safety.

In recent decades, a comprehensive new framework for the theory and design of control systems has emerged. This framework is based on a radically different foundation from the conventional approach. It treats a range of significant and ubiquitous design problems, including those of critical systems, more effectively than the conventional framework. Control Systems Design brings together contributions from the originators of the new framework in which they explain, expand and revise their research work in the field with more recent and entirely novel material.

The book also demonstrates how the conventional design framework can be made more effective by the use of the principle of inequalities. It is divided into four parts:

• basic principles, including those of matching and inequalities with adjustments for robust matching and matching based on H-infinity methods and linear matrix inequalities;
• computational methods, including matching conditions for transient inputs and design of a sampled-data control system;
• search methods including search with simulated annealing, genetic algorithms and evaluation of the node array method;
• case studies, including applications in distillation, benchmarking critical control of magnetic levitation systems and the use of the principle of matching in cruise control.

This book will be of great interest to academics and institutional researchers in control system design and to those studying for higher degrees in this area.
