A Raphael Madonna and Child Oil Painting: A Forensic Analytical Evaluation

by Howell G. Edwards

This book presents a comprehensive forensic analysis of an oil painting depicting a Madonna and Child in a tondo format, previously thought to be a Victorian copy. Detailed historical and scientific studies confirm that this painting was, in fact, created by Raphael around 1512 as a study for his renowned Sistine Madonna, commissioned by Pope Julius II as an altarpiece for the monastic church of San Sisto in Piacenza. The painting underwent rigorous forensic examination, combining historical research with both invasive and non-invasive scientific imaging techniques. The analysis utilized advanced physical and chemical instrumentation to determine the painting's authenticity and accurate chronological placement. A comparative review of published chemical analyses of pigments, dyes, and substrates used in Raphael’s works from collections worldwide is included. Additionally, this study explores the innovative use of artificial intelligence (AI) for facial comparison between the figures in the tondo painting, the Sistine Madonna, and other Raphael artworks. These AI-generated insights provide novel information about the identities of Raphael’s models and shed light on his working techniques, as well as those of his associates.

A Rapid Introduction to Adaptive Filtering (SpringerBriefs in Electrical and Computer Engineering)

by Hernan Rey Leonardo Rey Vega

In this book, the authors provide insights into the basics of adaptive filtering, which are particularly useful for students taking their first steps into this field. They start by studying the problem of minimum mean-square-error filtering, i.e., Wiener filtering. Then, they analyze iterative methods for solving the optimization problem, e.g., the Method of Steepest Descent. By proposing stochastic approximations, several basic adaptive algorithms are derived, including Least Mean Squares (LMS), Normalized Least Mean Squares (NLMS) and Sign-error algorithms. The authors provide a general framework to study the stability and steady-state performance of these algorithms. The affine Projection Algorithm (APA) which provides faster convergence at the expense of computational complexity (although fast implementations can be used) is also presented. In addition, the Least Squares (LS) method and its recursive version (RLS), including fast implementations are discussed. The book closes with the discussion of several topics of interest in the adaptive filtering field.

Rare

by Keith Veronese

How will your life change when the supply of tantalum dries up? You may have never heard of this unusual metal, but without it smartphones would be instantly less omniscient, video game systems would falter, and laptops fail. Tantalum is not alone. Rhodium. Osmium. Niobium. Such refugees from the bottom of the periodic table are key components of many consumer products like cell phones, hybrid car batteries, and flat screen televisions, as well as sophisticated medical devices and even weapon systems. Their versatile properties have led manufacturers to seek these elements out to maximize longevity, value, and efficiency, but not without a human price. In addition to explaining the chemistry behind rare earth metals, Rare delves into the economic and geopolitical issues surrounding these "conflict minerals," blending tales of financial and political struggles with glimpses into the human lives that are shattered by the race to secure them. In the past decade, the Congo has been ravaged by tribal wars fought to obtain control of tantalum, tungsten, and tin supplies in the region, with over five million people dying at the crossroads of supply and demand. A burgeoning black market in China, Africa, and India is propped up by school-age children retrieving and purifying these metals while risking their lives and health in the process. Fears of future political struggles inside China, the world's largest supplier of these metals, have already sent the United States, Great Britain, and Japan racing to find alternative sources.Will scientists be able to create lab substitutes for some or all of these metals? Will Afghanistan be the next big supplier of rare metals? What happens when the limited supply runs out? Whatever the answers, it is clear that our modern lifestyle, dependent on technology, is far from stable.From the Hardcover edition.

The Rare and the Beautiful: How the Garman Sisters Captured the Heart of Bohemian London

by Cressida Connolly

Like the better-known Mitfords, the Garman sisters took center stage in Bohemian London during the first half of the twentieth century. Beautiful, flamboyant, and headstrong, they broke away from middle-class conventions, seducing and inspiring a generation of artists. Kathleen, an enigmatic artist's model and aspiring pianist, was the lover and, later, wife of controversial American-born sculptor Jacob Epstein. Mary married the maverick poet Roy Campbell, whose verse attack on the Bloomsbury group following Mary's affair with Vita Sackville-West was the literary scandal of the epoch. Lorna, the youngest and most beautiful of the sisters, was the lover of both the painter Lucian Freud and the poet Laurie Lee.The Rare and the Beautiful offers the first portrait of a beguiling band of eccentric siblings who possessed an uncanny ability to turn heads, break hearts, and spark creative genius. Set against the exciting backdrop of London's decadent subculture, it evokes their extraordinary milieu of high culture, drama, and scandal.

Rare Earth Elements

by Volker Zepf

This thesis deals with Rare Earth Elements (REE), especially with neodymium used in permanent magnets, from a very scientific basis by providing basic research data. Despite the fact that REE are newsworthy and very important elements for a considerable bandwidth of todays' technologies, accompanied by the monopolistic supply-situation and Chinese politics, there are inexplicable data discrepancies about REE which have been recognized frequently but usually have not been addressed accordingly. So this analysis started with the hypothesis that the four application areas, namely computer hard disk drives (HDD), mobile phones, wind turbines and e-mobility (automotive traction), account for about 80% of the global annual neodymium-demand. The research methodology was a laboratory analysis of the composition of used magnets for HDDs and mobile phones and a literature and official report analysis of wind turbine and automotive neodymium use. The result was amazing and the hypothesis had to be withdrawn as these four areas only account for about 20% of neodymium use. This result raises some questions concerning actual use and thus potential recycling options.

Rare Earth Frontiers: From Terrestrial Subsoils to Lunar Landscapes

by Julie Michelle Klinger

Rare Earth Frontiers is a work of human geography that serves to demystify the powerful elements that make possible the miniaturization of electronics, green energy and medical technologies, and essential telecommunications and defense systems. Julie Michelle Klinger draws attention to the fact that the rare earths we rely on most are as common as copper or lead, and this means the implications of their extraction are global. Klinger excavates the rich historical origins and ongoing ramifications of the quest to mine rare earths in ever more impossible places.Klinger writes about the devastating damage to lives and the environment caused by the exploitation of rare earths. She demonstrates in human terms how scarcity myths have been conscripted into diverse geopolitical campaigns that use rare earth mining as a pretext to capture spaces that have historically fallen beyond the grasp of centralized power. These include legally and logistically forbidding locations in the Amazon, Greenland, and Afghanistan, and on the Moon. Drawing on ethnographic, archival, and interview data gathered in local languages and offering possible solutions to the problems it documents, this book examines the production of the rare earth frontier as a place, a concept, and a zone of contestation, sacrifice, and transformation.
