This book is about musical rhythm. More precisely, it is concerned with computer programs that automatically extract rhythmic descriptions from musical audio signals. New algorithms are presented for tempo induction, tatum estimation, time signature determination, swing estimation, swing transformations and classification of ballroom dance music styles. These algorithms directly process digitized recordings of acoustic musical signals. The backbones of these algorithms are rhythm periodicity functions: functions measuring the salience of a rhythmic pulse as a function of the period (or frequency) of the pulse, calculated from selected instantaneous physical attributes (henceforth features) emphasizing rhythmic aspects of sound. This book substantially contributes to the field of computational rhythm description by proposing an unifying functional framework; by reviewing the architecture of many existing systems with respect to individual blocks of this framework; by reporting on the first public evaluation of tempo induction algorithms; and by identifying promising research directions.
To the author's knowledge this book is the first to review the whole field of the Alpha rhythm component of the electroencephalogram (EEG). It reviews the classical studies from the 1930s through the 1980s when EEG research became dominated by event-related potential studies. Renewed interest in the alpha rhythm developed in the 1990s when neuronal oscillations became a major focus of interest in the neurophysiology of brain function. Many of the later studies of alpha activity that resulted from this development are fully documented in the book.
In this book Patrick Hegarty summarises the key principles gleaned from helping 1000's of people transition into new vitality and fruitfulness in their faith. By understanding the evolving partnership you have with God, you can unlock your next stage of personal growth and impact in the world. The Rhythms of Grace are powerful and simple ways to engage with God that unlock the next step in your spiritual journey. In this book you will learn how to more profoundly experience: FAITH: Learn how to rely on God more fully by activating the rhythm of SPIRIT & TRUTH. HOPE: Overcome sin, and live from the power and perspective of heaven by fully understanding how to REPENT & BELIEVE. LOVE: Bear lasting fruit in your life by abiding in Christ through the rhythm of FAITH & DEEDS. You can't live out an IMPOSSIBLE calling in your own STRENGTH. If you want to grow you will need a new rhythm! Every part of the Christian life is impossible to attain without God's help. And yet we remain largely ignorant on how to engage with His grace and power. Our relationship with God evolves, and so we must emphasize different aspects as we mature in our journey. The faith, hope, and love of today will not be enough for your tomorrow! This book gives you the simple keys to unlock each phase of your walk with Christ. If you want to grow you will need a new rhythm! This book is a great way for CHURCHES and GROUPS to highlight and launch spiritual growth. Use it as a church-wide campaign!
