Transition Redesigned deals with the philosophical bases of different types of transition: change in the economy, organizational/institutional change, and change in social and individual relationships. The editors' primary goal is to give further impetus to a much-needed worldwide debate on the issue of transition towards a better future. The volume reviews transitions made in different areas of human activity, assesses their relevancy, and analyzes their contexts. During this century, different organizations and institutions will undergo a level of radical and global change that has rarely been seen. The expected shift must be addressed in terms of a multidimensional transition toward building a sustainable society. Do we have an understanding of transition relevant to the task of meeting at least some of the challenges presented in this volume? Do we need a radical innovation for redesigning the transition that may enforce real social and ethical responsibilities into organizational practice on different levels and bring to life new ideas? Transition Redesigned seeks to answer these questions.
The Ray And Wave Theory Of Lenses
RRP $137.95
Calculations on lens systems are often marred by the unjustifiable use of the small-angle approximation. This book describes in detail how the ray and wave pictures of lens behaviour can be combined and developed into a theory capable of dealing with the large angles encountered in real optical systems. A distinct advantage of this approach is that Fourier optics appears naturally, in a form valid for arbitrarily large angles. The book begins with extensive reviews of geometrical optiks, eikonal functions and the theory of wave propagation. The propagation of waves through lenses is then treated by exploiting the close connection between eikonal function theory and the stationary phase approximation. Aberrations are then discussed, and the book concludes with various applications in lens design and analysis, including chapters on laser beam propagation and diffractive optical elements. Throughout, special emphasis is placed on the intrinsic limitations of lens performance. The many practical insights it contains, as well as the exercises with their solutions, will be of interest to graduate students as well as to anyone working in optical design and engineering.
