Spectrum
Since the dawn of Second Earth, the Island of Fire has awaited the arrival of the one mage whose dominion over the global magic network—the spectrum—will enable her to rescue the primitive, totalitarian nation from obscurity. But, when Scarlet July is born, her extraordinary magic unexpectedly renders her a third-class citizen, denied the right to education, employment and, ultimately, life. Evading execution, Scarlet finds herself orphaned and alone, struggling to survive and find her purpose. Three-thousand miles north, in the ice island of Ichthyosis, Diving Fleet Commander Cease Lechatelierite has never had to question his purpose. Since childhood, he’s been set on track toward one goal: to annihilate magekind. But, when he comes face-to-face with Scarlet and learns her story, what will become of the convictions he’s held since birth? This six-part series follows an eclectic cast of teens fighting to find their place in the wars plaguing their dystopian world. From fantastical world-building, to combat sequences, to geopolitics, to the exploration of a soldier's psyche, to social commentary, to the turmoil of young adulthood, to forbidden romance, Spectrum is a fast-paced, character-driven, sci-fi/fantasy adventure for the Hunger Games generation.
Vibration Spectrum Analysis
"Written for vibration analysts, predictive maintenance specialists, field mechanics, and a wide variety of engineers, Vibration Spectrum Analysis assumes no prior knowledge of advanced mathematics or mechanical engineering. It carefully guides the reader through sophisticated analysis techniques in a logical, easy-to-understand manner."--BOOK JACKET.
Mapping the Spectrum
Ever since the boom of spectrum analysis in the 1860s, spectroscopy has become one of the most fruitful research technologies in analytic chemistry, physics, astronomy, and other sciences. This book is the first in-depth study of the ways in which various types of spectra, especially the sun's Fraunhofer lines, have been recorded, displayed, and interpreted. The book assesses the virtues and pitfalls of various types of depictions, including hand sketches, woodcuts, engravings, lithographs and, from the late 1870s onwards, photomechanical reproductions. The material of a 19th-century engraver or lithographer, the daily research practice of a spectroscopist in the laboratory, or a student's use of spectrum posters in the classroom, all are looked at and documented here. For pioneers of photography such as John Herschel or Hermann Wilhelm Vogel, the spectrum even served as a prime test object for gauging the color sensitivity of their processes. This is a broad, contextual portrayal of the visual culture of spectroscopy in the 19th and early 20th centuries. The illustrations are not confined to spectra--they show instruments, laboratories, people at work, and plates of printing manuals. The result is a multifacetted description, focusing on the period from Fraunhofer up to the beginning of Bohr's quantum theory. A great deal of new and fascinating material from two dozen archives has been included. A must for anyone interested in the history of modern science or in research practice using visual representations.
