Inverse problems arise whenever one tries to calculate a required quantity from given measurements of a second quantity that is associated to the first one. Besides medical imaging and non-destructive testing, inverse problems also play an increasing role in other disciplines such as industrial and financial mathematics. Hence, there is a need for stable and efficient solvers. The book is concerned with the method of approximate inverse which is a regularization technique for stably solving inverse problems in various settings such as L2-spaces, Hilbert spaces or spaces of distributions. The performance and functionality of the method is demonstrated on several examples from medical imaging and non-destructive testing such as computerized tomography, Doppler tomography, SONAR, X-ray diffractometry and thermoacoustic computerized tomography. The book addresses graduate students and researchers interested in the numerical analysis of inverse problems and regularization techniques or in efficient solvers for the applications mentioned above.

In recent years there has been a great influx of sources for business and financial news, yet the hope that this financial media boom would lead to the democratization of the financial markets has not been realized. Thomas Schuster's The Markets and the Media explores why the expansion of economic communication has proven to be of only limited benefit, arguing that the financial media boom has had negative repercussions resulting in substantial costs for the individual as well as the system. The Markets and the Media stands alone in its class: It is the first comprehensive analysis focusing on the complex, intricate, and often puzzling relationship between the financial markets and the mass media. Featuring a comprehensive business bibliography, this book is a must-read for both finance experts and media scholars.

In Anbetracht der standigen Ausweitung des Einflussbereichs der Massenmedien muss man sich die Frage stellen, ob das enorme Informationsangebot tatsachlich zur Herausbildung eines vielfaltigen Meinungsspektrums fuhrt oder ob die Nachrichten-Schwemme nicht vielmehr eine meinungsverflachende und betaubende Wirkung hat. Fest steht zumindest, dass die Moglichkeiten einer intendierten Wirklichkeitsverfalschung mit den modernen elektronischen Medien eine vollig neue Qualitat erfahren haben.
