The Theory Of The Moir Phenomenon

Who has not noticed, on one o~casion or another, those intriguing geometric patterns which appear at the intersection Of repetitive structures such as two far picket fences on a hill, the railings on both sides of a bridge, superposed layers of fabric, or folds of a nylon curtain? This fascinating phenomenon, known as the moire effect, has found useful applications in several fields of science and technology, such as metrology, strain analysis or even document authentication and anti-counterfeiting. However, in other situations moire patterns may have an unwanted, adverse effect. This is the case in the printing world, and, in particular, in the field of colour reproduction: moire patterns which may be caused by the dot-screens used for colour printing may severely deteriorate the image quality and tum into a real printer's nightmare. The starting point of the work on which this book is based was, indeed, in the research of moire phenomena in the context of the colour printing process. The initial aim of this research was to understand the nature and the causes of the superposition moire patterns between regular screens in order to find how to avoid, or at least minimize, their adverse effect on colour printing. This interesting research led us, after all, to a much more far reaching mathematical understanding of the moire phenomenon, whose interest stands in its own right, independently of any particular application.

A different face of coal than that seen by miners. Focusses on the conversion of coal to a liquid and the clean utilization of coal. Among topics discussed are surface phenomena involved in the beneficiation processes, flotation and spherical agglomeration, and the modification of coal-fluid interfaces.

During the past decade, plenty of studies have been carried out in the literature to address the coordination and cooperation problems in complex adaptive systems, and have continued to grow. This Research Topic eBook publishes 14 papers by 39 authors, and most of these published papers present current research illustrating the depth and breadth of ongoing work on the coordination and cooperation problems in complex adaptive systems. It thus provides a timely discussion for researchers on the hotspots and challenges of the study on coordination and cooperation in theoretical models and applied systems.

With a Foreword writer Steven Weinberg In this richly illustrated book, Nobel Laureate Gerard 't Hooft and Theoretical Physicist Stefan Vandoren describe the enormous diversity of natural phenomena that take place at different time scales. In the tradition of the bestseller Powers of Ten, the authors zoom in and out in time, each step with a factor of ten. Starting from one second, time scales are enlarged until processes are reached that take much longer than the age of the universe. After the largest possible eternities, the reader is treated to the shortest and fastest phenomena known. Then the authors increase with powers of ten, until again the second is reached at the end of the book. At each time scale, interesting natural phenomena occur, spread over all scientific disciplines: orbital and rotation periods of planets and stars, decay times of elementary particles and atoms, biological rhythms and evolution processes, but also the different geological time scales.

Keywords:Time;natural Phenomena;Time Scales;Age of the Universe;Powers of TenReviews: “The somewhat facetious narrating style and the abundance of illustrations are so inviting and rather addictive once you picked up the book.” European Mathematical Society “Pleasingly accessible volume that will give pleasure to academics, students, connoisseurs of coffee-table books and even the people who compile questions for Trivial Pursuit … Can be enjoyed as a source of scientific stories and images, as an unusual perspective on history, as a popular account of modern physics, and so on. Underneath them all is a wealth of serious science that will give readers insights into abstract fundamental ideas via concrete realities … Every science teacher would benefit from reading Time in Powers of Ten, but I hope it will have an even wider reach.” Times Higher Education “The authors have compiled a refreshing mix of historical anecdotes and examples from music to sport and biology to astronomy to lighten up the heavier taste of particle physics and cosmology… It is both an enjoyable read and very pleasant to browse at leisure… It fully conveys the authors' amazement at — as Feynman put it — our fantastically marvellous universe.” Nature Physics “The authors introduce the reader to the diversity of nature in a novel way by describing typical and interesting phenomena that occur or have occurred on many different time scales. The time scales considered differ by powers of ten, as the title of the book says, from the shortest times of which we have knowledge to the longest. I am sure many readers will enjoy the book as I have.” Edward Witten, Fields Medalist “Time is an essential dimension of life. Indeed, its remarkable and awesome variation of scale shapes the natural world. This book by Gerard 't Hooft and Stefan Vandoren gives us an exposé of a wide range of natural phenomena and their associated time scales, spanning the very small, the very large, and the life events of our universe. The book is elegantly illustrated and should be an enjoyable read for anyone interested in a deeper understanding of the fourth dimension, time, and how it shapes our lives.” Ahmed Zewail, Nobel Laureate in Chemistry “Like the original Powers of Ten, it is a wonderful book for flipping through and thinking about puzzles and is a good introduction to basics like how to tell a quark from a lepton.” The Dispatch “The book reveals the extraordinary complexity of our universe — it is a fascinating journey.” CERN Courier “This is a fascinating coffee-table book ranging from the unimaginably huge to the unimaginably tiny.” Ultramicroscopy “You can read the book in any direction. Delving into the index takes you on a mystery tour of the time domain. Helpfully, all the major phenomena are gathered together on an illustrated time line. This book is definitely one for your reading list.” Physics Education

In this book experts from quite different fields present simulations of social phenomena: economists, sociologists, political scientists, psychologists, cognitive scientists, organisational scientists, decision scientists, geographers, computer scientists, AI and AL scientists, mathematicians and statisticians. They simulate markets, organisations, economic dynamics, coalition formation, the emergence of cooperation and exchange, bargaining, decision making, learning, and adaptation. The history, problems, and perspectives of simulating social phenomena are explicitly discussed.
