Buch. Condición: Neu. Neuware - Morality in context is a timely topic. A debate between philosophers and social scientists is a good way to approach it. Why is there such a booming interest in morality and why does it focus on context One starting point is the change in the sociostructural and sociocultural conditions of modern societies. This involves change in the empirical conditions of moral action and in the social demand on morality. As these changes are accounted for and analyzed in the social sciences, new perspectives emerge that give rise to new ways of framing issues and problems. These problems are best addressed by way of cooperation between philosophers and social scientists. As Habermas (1990) has pointed out in a much cited paper, philosophers depend on social science to fill in the data they require to answer the questions raised by philosophy in its 'placeholder' function. The reverse also holds true: Social science needs the conceptual clarifications that philosophy can provide. With respect to morality, such mutual interchanges are of particular importance the contributions to this book show convincingly.

Buch. Condición: Neu. Neuware - For more than forty years, the equation y'(t) = Ay(t) + u(t) in Banach spaces has been used as model for optimal control processes described by partial differential equations, in particular heat and diffusion processes. Many of the outstanding open problems, however, have remained open until recently, and some have never been solved. This book is a survey of all results know to the author, with emphasis on very recent results (1999 to date).

Buch. Condición: Neu. Neuware - Cold formed structural members are being used more widely in routine structural design as the world steel industry moves from the production of hot-rolled section and plate to coil and strip, often with galvanised and/or painted coatings. Steel in this form is more easily delivered from the steel mill to the manufacturing plant where it is usually cold-rolled into open and closed section members.This book not only summarises the research performed to date on cold form tubluar members and connections but also compares design rules in various standards and provides practical design examples.

Buch. Condición: Neu. Neuware - Nonlinearity and Chaos in Molecular Vibrations deals systematically with a Lie algebraic approach to the study of nonlinear properties of molecular highly excited vibrations. The fundamental concepts of nonlinear dynamics such as chaos, fractals, quasiperiodicity, resonance, and the Lyapunov exponent, and their roles in the study of molecular vibrations are presented.The 20 chapters cover the basic ideas, the concept of dynamical groups, the integrable two-mode SU(2) system, the unintegrable three-mode SU(3) system, the noncompact su(1,1) algebraic application, su(3) symmetry breaking and its application and the quantal effect of asymmetric molecular rotation. Emphasis is given to: resonance and chaos, the fractal structure of eigencoefficients, the C-H bend motion of acetylene, regular and chaotic motion of DCN, the existence of approximately conserved quantum numbers, one-electronic motion in multi-sites, the Lyapunov exponent, actions of periodic trajectories and quantization, the H function and its application in vibrational relaxation as well as the Dixon dip and its destruction and chaos in the transitional states. This approach bridges the gap between molecular vibrational spectroscopy and nonlinear dynamics.The book presents a framework of information that readers can use to build their knowledge, and is therefore highly recommended for all those working in or studying molecular physics, molecular spectroscopy, chemical physics and theoretical physics.
