The Labyrinth Key

In a secret war waged in worlds both virtual and real, the fates of nations depend on the definitive weapon. And that weapon is knowledge—knowledge to die for. . . . The race is heating up between the U.S. and China to develop a quantum computer with infinite capabilities to crack any enemy’s codes, yet keep secure its own secrets. The government that achieves this goal will win a crucial prize. No other computer system will be safe from the reach of this master machine. Dr. Jaron Kwok was working for the U.S. government to build such a computer. But in a posh hotel in Hong Kong, a Chinese policewoman sifts through the bizarre, ashlike remains of what’s left of the doctor. With the clock ticking, alliances will be forged—and there are those who will stop at nothing to discover what the doctor knew. As the search for answers intensifies, it becomes chillingly clear that the quantum computer both sides so desperately want will be more powerful, more dangerous than anyone could have ever imagined. For in the twenty-first century, machines become gods, gods become machines, and the once-impossible now lies within reach. The key to unlimited knowledge will create the ultimate weapon of mass destruction—or humanity’s last chance to save itself. . . .

Fifteen years ago, 8-year-old Ethan Jones watched a stranger bury something in the mining ruins of the Rhyolite Desert, Nevada. Even at his young age, he knew what he'd just seen was important. In present day, a US Navy SEAL takes refuge in a secret chamber beneath the ancient streets of Syria and discovers an unusual stone artifact, like nothing he'd ever seen before. When news of the discovery reaches Sam Reilly, he is forced to return to his past, where his search for the Master Builders originated - and complete a mission he'd hoped could have stayed unfinished forever.

Labyrinth spillways are almost as old as dam engineering. In spite of the fact that they appear as a very good technical-economical compromise, only 0.1% of large dams are equipped with such weirs. The main reason for this is that traditional labyrinth weirs usually cannot be installed on top of concrete gravity dams as they require a large foundat

Fourteen-year-old Princess Xenodice tries to prevent the death of her half-brother, the Minotaur, at the hands of the Athenian prince, Theseus, who is aided by Icarus, Daedalus, and her sister Ariadne.

The critically acclaimed author of Lightpaths breaks out with a thrilling novel of quantum cryptography and the ultimate arms race.

Dam engineering is currently experiencing a strong revival of labyrinth oriented weirs. Labyrinth weirs, with a repetitive constructional character and an increased specific discharge capacity, are a very good technical-economical compromise. The concept of Piano Key Weir (PKW), with alveoli developed in overhangs from a reduced support area, enabl

Since the first implementation by Electricité de France on the Goulours dam (France) in 2006, the Piano Key Weir has become a more and more applied solution to increase the discharge capacity of existing spillways. In parallel, several new large dam projects have been built with such a flood control structure, usually in combination with gates. Today, more than 25 Piano Key Weirs are in operation or under construction all over the world. More than 15 years of research and development have enabled detailed investigations of the hydraulic and structural behaviour of the Piano Key Weir complex structure and have provided more and more accurate design equations. Following the proceedings of the first two workshops held in Liege (Belgium – 2011) and Paris (France – 2013), Labyrinth and Piano Key Weirs III collects the contributions presented by people with varied background, from researchers to practitioners, at the 3rd International Workshop on Labyrinth and Piano Key Weirs - PKW 2017 (22-24 February 2017, Qui Nhon, Vietnam). The papers, reviewed and accepted by an International Scientific Committee, summarize the current state-of-the-art on Piano Key Weirs from a theoretical to a practical point of view, and present most of the main projects in operation or under construction. Labyrinth and Piano Key Weirs III is thus a reference for students, practitioners and researchers interested in Dams Engineering.

Ancient and medieval labyrinths embody paradox, according to Penelope Reed Doob. Their structure allows a double perspective—the baffling, fragmented prospect confronting the maze-treader within, and the comprehensive vision available to those without. Mazes simultaneously assert order and chaos, artistry and confusion, articulated clarity and bewildering complexity, perfected pattern and hesitant process. In this handsomely illustrated book, Doob reconstructs from a variety of literary and visual sources the idea of the labyrinth from the classical period through the Middle Ages. Doob first examines several complementary traditions of the maze topos, showing how ancient historical and geographical writings generate metaphors in which the labyrinth signifies admirable complexity, while poetic texts tend to suggest that the labyrinth is a sign of moral duplicity. She then describes two common models of the labyrinth and explores their formal implications: the unicursal model, with no false turnings, found almost universally in the visual arts; and the multicursal model, with blind alleys and dead ends, characteristic of literary texts. This paradigmatic clash between the labyrinths of art and of literature becomes a key to the metaphorical potential of the maze, as Doob's examination of a vast array of materials from the classical period through the Middle Ages suggests. She concludes with linked readings of four "labyrinths of words": Virgil's Aeneid, Boethius' Consolation of Philosophy, Dante's Divine Comedy, and Chaucer's House of Fame, each of which plays with and transforms received ideas of the labyrinth as well as reflecting and responding to aspects of the texts that influenced it. Doob not only provides fresh theoretical and historical perspectives on the labyrinth tradition, but also portrays a complex medieval aesthetic that helps us to approach structurally elaborate early works. Readers in such fields as Classical literature, Medieval Studies, Renaissance Studies, comparative literature, literary theory, art history, and intellectual history will welcome this wide-ranging and illuminating book.
