Book Description
In recent years there has been an explosion of interest in wavelets, in a wide range of fields in science and engineering and beyond. This book brings together contributions from researchers from disparate fields, both in order to demonstrate to a wide readership the current breadth of work in wavelets, and to encourage cross-fertilization of ideas. It demonstrates the genuinely interdisplinary nature of wavelet research and applications. Particular areas covered include turbulence, statistics, time series analysis, signal and image processing, the physiology of vision, astronomy, economics and acoustics. Some of the work uses standard wavelet approaches and in other cases new methodology is developed. The papers were originally presented at a Royal Society Discussion Meeting, to a large and enthusiastic audience of specialists and non-specialists.

Book Description
Much work has been done on trying to gain insight into the dynamics of accreting systems, such as black hole and neutron star binaries, by analyzing timing measurements from X-ray telescopes. In this thesis we present a novel approach to this problem using a kurtosis measure of the wavelet distribution obtained from the light curve to quantify the presence of intermittent activity. This method is applied to large RXTE data sets for GRS 1915+105, and Cygnus X-1. We demonstrate a new approach to reveal bursting modes. Negative correlation between the presence of a low frequency QPO in the Cygnus X-1 Fourier power spectrum and a wavelet kurtosis indicator of temporal intermittency is observed. A possible interpretation of this anti-correlation is developed using a "dripping handrail" transient chaos model.

Book Description
A new threshold for the existence of weak solutions to the incompressible Euler equations To gain insight into the nature of turbulent fluids, mathematicians start from experimental facts, translate them into mathematical properties for solutions of the fundamental fluids PDEs, and construct solutions to these PDEs that exhibit turbulent properties. This book belongs to such a program, one that has brought convex integration techniques into hydrodynamics. Convex integration techniques have been used to produce solutions with precise regularity, which are necessary for the resolution of the Onsager conjecture for the 3D Euler equations, or solutions with intermittency, which are necessary for the construction of dissipative weak solutions for the Navier-Stokes equations. In this book, weak solutions to the 3D Euler equations are constructed for the first time with both non-negligible regularity and intermittency. These solutions enjoy a spatial regularity index in L^2 that can be taken as close as desired to 1/2, thus lying at the threshold of all known convex integration methods. This property matches the measured intermittent nature of turbulent flows. The construction of such solutions requires technology specifically adapted to the inhomogeneities inherent in intermittent solutions. The main technical contribution of this book is to develop convex integration techniques at the local rather than global level. This localization procedure functions as an ad hoc wavelet decomposition of the solution, carrying information about position, amplitude, and frequency in both Lagrangian and Eulerian coordinates.

Book Description
Solar photovoltaic (PV) systems have experienced a tremendous increase in installed capacity in the past decade. Although solar PV power is environmentally friendly and can be used to extend the life of fossil fuel reserves, it is of an intermittent nature. Through nine chapters, this book provides an understanding of solar PV systems’ power output intermittency and its impacts on power systems. The first part of the book highlights the source of the variability of both solar irradiation and PV systems’ output, while the second highlights the impact of factors such as temperature and dust on PV systems’ output variability through case studies. The third part highlights the impacts of PV systems’ output variability of the design and operation of power systems. This book will appeal to students, researchers, operators, engineers, designers, and policymakers working on solar PV or electric power systems design, planning, or operation.

Book Description
The dynamics of many nonlinear systems gravitate around a few common central themes: intermittency, order/coherence and disorder. Intermittency may be the universal outcome of a large class of nonlinear systems; however, the universality properties of specific nonlinear systems remain open questions. This volume consists of articles by leading figures who all participated in a workshop held at the Newton Institute in Cambridge.

Book Description
How intermittent fasting can enhance resilience, improve mental and physical performance, and protect against aging and disease. Most of us eat three meals a day with a smattering of snacks because we think that’s the normal, healthy way to eat. This book shows why that’s not the case. The human body and brain evolved to function well in environments where food could be obtained only intermittently. When we look at the eating patterns of our distant ancestors, we can see that an intermittent fasting eating pattern is normal—and eating three meals a day is not. In The Intermittent Fasting Revolution, prominent neuroscientist Mark Mattson shows that intermittent fasting is not only normal but also good for us; it can enhance our ability to cope with stress by making cells more resilient. It also improves mental and physical performance and protects against aging and disease. Intermittent fasting is not the latest fad diet; it doesn’t dictate food choice or quantity. It doesn’t make money for the pharmaceutical, processed food, or health care industries. Intermittent fasting is an eating pattern that includes frequent periods of time with little or negligible amounts of food. It is often accompanied by weight loss, but, Mattson says, studies show that its remarkable beneficial effects cannot be accounted for by weight loss alone. Mattson—whose pioneering research uncovered the ways that the brain responds to fasting and exercise—explains how thriving while fasting became an evolutionary adaptation. He describes the specific ways that intermittent fasting slows aging; reduces the risk of diseases, including obesity, Alzheimer’s, and diabetes; and improves both brain and body performance. He also offers practical advice on adopting an intermittent fasting eating pattern as well as information for parents and physicians.
