  • It is with great pleasure that we present this completely revised English edition of our book How Does MRI Work? An Introduction to the Physics and Function of Magnetic Resonance Imaging only two years after publication of the first English edition. We are particularly pleased that our introductory textbook met with great approval in the English-speaking world and not just in the German-speaking countries. This success has been an enormous incentive for us to further improve and update the text. For this reason, we are now presenting a second edition.

  • It is our pleasure to present the Proceedings of the VI International Workshop on Relativistic Aspects of Nuclear Physics (RANP 2000). This time, the meeting took place in Tabatinga, a pleasant beach on the southern coast of Brazil, for the first time out of the city of Rio de Janeiro. This series of workshops started in 1989, aiming to stimulate Brazilian scientific activities on Relativistic Nuclear Physics, especially among young researchers and graduate students.

  • In this paper we present the implementation of a digital lock-in amplifier (LIA) completely based on Labview with a general-purpose data acquisition board (or a high quality sound card) and a high-gain low-noise amplifier. The signal analysis is processed by the software. We describe some characteristics of the LIA including output voltage vs. frequency and output phase vs. noise. The LIA can be used to measure the small signals, even in presence of broadband noise which is several times greater than the signal itself. Since the signal processing takes place on the computer, ...

  • Methodological reductionism is a driving force of scientific thinking. Unlike the more controversial, and philosophically dubious, connotations of the term, methodological reductionism embodies a general principle of intellectual parsimony. It does not establish debatable hierarchies among pedagogically distinct scientific areas, it does not seek to identify equally controversial ultimate constituents of reality. Instead, it attempts the consolidation of a collection of more or less intuitively connected items into a more general item, of which they become refinements or specializations.

  • Beginning with modest initial attempts in roughly the 1960s, digital image processing has become a recognized field of science, as well as a broadly accepted methodology, to solve practical problems in many different kinds of human activities. The applications encompass an enormous range, starting perhaps with astronomy, geology, and physics, via medical, biological, and ecological imaging and technological exploitation, up to the initially unexpected use in humane sciences, e.g., archaeology or art history.

  • Fractal signal models are important in a wide range of signal processing applications. For example, they are often well-suited to analyzing and processing various forms of natural and man-made phenomena. Likewise, the synthesis of such signals plays an important role in a variety of electronic systems for simulating physical environments. In addition, the generation, detection, and manipulation of signals with fractal characteristics has become of increasing interest in communication and remote-sensing...

  • Wireless communications is rapidly becoming one of the ubiquitous technological underpinnings of modern society (such as electric power, fossil fuels, automobiles, etc.). Few people think about the technology within their mobile phones, remote controls, garage door openers, GPS navigation devices, and so on. They are always at hand and reliably work for the user. Yet even within the electrical engineering (EE) community, radio communication techniques have a reputation as a “Black Art” that can only be successfully practiced by “RF people”. This is changing, albeit slowly.
