The performance by Mariss Jansons and the London Philharmonic is excellent. Jansons fully exploits some striking moments in the 15th, and generally takes a balanced approach, at different times selecting tempi that are slower or faster than the norm, with high quality orchestral playing. In Jansons’ 15th, his Adagio is particularly successful. Jansons effectively builds to a powerful climax at the end of the long finale.

This book deals fundamentally with the quality and usability of communication technology systems. To this end, the necessary terms are first introduced, and the fundamentals of psychophysics and psychometrics are established. Based on this, the cycle of human-oriented system development is presented. The measurement and prediction of quality and usability are then illustrated by practical examples of communication engineering systems. In particular, systems for information transmission (telephony, VoIP, IP-TV), speech dialog systems, and multimodal dialog systems are discussed. Finally, models for estimating quality and usability in the development phase of such systems are presented.

The name Mark Baker may not be immediately recognizable to many, but for liner note/album credits junkies, it signifies top shelf AOR songwriting. Whether it be anthems or ballads, a Mark Baker song means memorable hooks and a big chorus. Mark Baker is the man behind the iconic Signal "Loud & Clear" album as well as many other songs, including tracks for .38 Special, Paris Black, Triumph and Boulevard.
