Yet another book on wavelets. There are many books on wavelets available, written for readers with different backgrounds. But the topic is becoming ever more important in mainstream signal processing, since the new JPEG2000 standard is based on wavelet techniques. Wavelet techniques are also impor tant in the MPEG-4 standard. So we thought that there might be room for yet another book on wavelets. This one is limited in scope, since it only covers the discrete wavelet trans form, which is central in modern digital signal processing. The presentation is based on the lifting technique discovered by W. Sweldens in 1994. Due to a result by I. Daubechies and W. Sweldens from 1996 this approach covers the same class of discrete wavelet transforms as the one based on two channel filter banks with perfect reconstruction. The goal of this book is to enable readers, with modest backgrounds in mathematics, signal analysis, and programming, to understand wavelet based techniques in signal analysis, and perhaps to enable them to apply such methods to real world problems. The book started as a set of lecture notes, written in Danish, for a group of teachers of signal analysis at Danish Engineering Colleges. The material has also been presented to groups of engineers working in industry, and used in mathematics courses at Aalborg University.

Today work, leisure, love, health, holidays, schooling and self-development seem to be flowing together in one big, chaotic mess. But in this book, the philosopher Anders Fogh Jensen explains that this mess has its own order: the project. We are dealing with time, space and each other in new ways - marked by temporarity, uncertainty, ad hoc solutions, overbookings, cancellations and the absence of clear expectations to the individual. The temporary 'yes' dominates our daily lives as the passage from one thing to another has become a chronic condition. The logic of the project can be found e.g. in dancing, in administration, in health politics, in football, in our love lives, in corporate culture and in what used to be referred to as private life. The book delves into these highly diverse examples from everyday life - and arrives at a contemporary diagnosis on that backdrop, describing the possibilities and problems that are created by today's project society.
