In the last decade the research in signal analysis was dominated by models that encompass nonstationarity as an important feature. This book presents the results of a workshop held in Grodek Polandin February 2013 which was dedicated to the investigation of cyclostationary signals. Its main objective is to highlight the strong interactions between theory and applications of cyclostationary signals with the use of modern statistical tools.

An important application of cyclostationary signals is the analysis of mechanical signals generated by a vibrating mechanism. Cyclostationary models are very important to perform basic operations on signals in both time and frequency domains. One of the fundamental problems in diagnosis of rotating machine is the identification of significant modulating frequencies that contribute to the cyclostationary nature of the signals. The book shows that there are modern tools available for analyzing cyclostationary signals without the assumption of gaussianity. Those methods are based on the ideas of bootstrap, subsampling and Fraction-of-time (FOT) models. The book is organised in two parts. The first part will be dedicated to pure theory on cyclostationarity. Applications are presented in the second part including several mechanical systems such as bearings, gears, with or without damages."

Ibiza is about beauty, not just the natural beauty of the landscape, the coast and mountains, the abundance of nature, but also the beauty in the spirit of the island. Water is a precious resource in Ibiza, and continuously pouring it into a lawn, or plants that need a lot of water, is both wasteful and time-consuming. If you want an abundant, lovely garden despite the Mediterranean heat and arid landscape, your best bet is to seek out drought-resistant garden plants. Not only will you save water and energy, but they are far more likely to survive long term and create a garden with character and complexity.
