A cognitive journey towards the reliable simulation of scattering problems using finite element methods, with the pre-asymptotic analysis of Galerkin FEM for the Helmholtz equation with moderate and large wave number forming the core of this book. Starting from the basic physical assumptions, the author methodically develops both the strong and weak forms of the governing equations, while the main chapter on finite element analysis is preceded by a systematic treatment of Galerkin methods for indefinite sesquilinear forms. In the final chapter, three dimensional computational simulations are presented and compared with experimental data. The author also includes broad reference material on numerical methods for the Helmholtz equation in unbounded domains, including Dirichlet-to-Neumann methods, absorbing boundary conditions, infinite elements and the perfectly matched layer. A self-contained and easily readable work.

The progressive convergence of global economic and social structures calls for a rethinking of management practices as they relate to cultural diversity and moral values. A key element for coping with this transformational phenomenon is the Aristotelian concept of Practical Wisdom, which helps us to do the right thing, in the right way, at the right time and for the right reasons. Expert academics and practitioners share their insights into contemporary theories and conventions for ethical decision-making in diverse cultural contexts. About the Editors Martina Stangel-Meseke - professor of business psychology. Christine Boven - professor of intercultural management. Gershon Braun - lecturer of business ethics. Andre Habisch - professor of economics. Nicolai Scherle - professor of intercultural management and diversity. Frank Ihlenburg - managing partner of a change management consultancy.
