Rosette

With the materials in this portfolio—20 sheets of brightly patterned paper, plus basic rosette techniques, 14 step-by-step projects, and endless ideas for inspiration—crafters will delight in making timeless and modern folded medallions that can accessorize any outfit, function as home décor, or be gifted as living scrapbook mementos.

Charts are presented for rapidly determining the principal strains and stresses, the maximum shear strain and stress, and the orientation of principal axes for data for 45 degrees strain rosettes. The charts may be used for analyzing the conventional data consisting of strains measured along three gage lines 45 degrees apart, but their application is more direct if the rosette data are obtained by means of special circuits that require the use of four gages 45 degrees apart.

With the CIA and intelligence apparatus compromised at the highest levels, Jim Faithen, an ex-Navy SEAL, and John Delaney, a mining engineer, think they have established a safe new beginning in Rio de Janeiro seeking minerals and gold. That is about to change. Just as they are approached by four men in suits, sniper fire rings out from a nearby rooftop. It appears the two men have more enemies than they realized. In their escape from enemies, they uncover a carefully planned scheme by the Russian Mafia and the Iranian Muslim hierarchy who attempt nuclear annihilation of the Unites States. Entering conspiracies of treachery propel them through city scapes and Brazilian jungles along with delightful street urchins, a powerful jungle drug lord, and an enigmatic shaman leader, while spies and crooked government operators joust on the hidden battlefields of the world. Yet, the jungle can bend the laws of nature as they manifest.

"Renowned luthier John S. Bogdanovich crafted the project shown inside for his own personal use. The design he presents is simple but elegant and is a composite of ideas borrowed from several different guitars admired for their tonal qualities and aesthetic details. In close-up photographs Bogdanovich invites you to stand by his side and follow the entire process from start to finish. He offers guidance through every step, and explains every decision, from the arrangement of his workbench and the selection of the wood, to tuning and setting up the instrument. Bogdanovich also provides a choice of alternative methods and materials -- to help you find your own style of working, and to enable you to add your personal touches to your project. By the time your instrument is finished, you'll have acquired a world of knowledge, from the difference between quartersawn and flat-sawn wood to the pros and cons of lacquer versus French polish. You'll have mastered dozens of skills, including bending and aminating wood and cutting and seating wire frets. Best of all, you'll have a beautiful instrument, designed to your own specifications, that will give pleasure to everyone who hears it." -- Book jacket.

Since the first edition of this book was published several new developments have been made in the field of the moiré theory. The most important of these concern new results that have recently been obtained on moiré effects between correlated aperiodic (or random) structures, a subject that was completely absent in the first edition, and which appears now for the first time in a second, separate volume. This also explains the change in the title of the present volume, which now includes the subtitle “Volume I: Periodic Layers”. This subtitle has been added to clearly distinguish the present volume from its new companion, which is subtitled “Volume II: Aperiodic Layers”. It should be noted, however, that the new subtitle of the present volume may be somewhat misleading, since this book also treats (in Chapters 10 and 11) moiré effects between repetitive layers, which are, in fact, geometric transformations of periodic layers, that are generally no longer periodic in themselves. The most suitable subtitle for the present volume would therefore have been “Periodic or Repetitive Layers”, but in the end we have decided on the shorter version.
