Against all odds, Rye and Sonia have survived the perils behind the gold and silver Doors. But Weld is still under threat, and Rye knows what he has to do. One Door remains a mystery—the ancient wooden Door that he has been drawn to from the beginning. For good or ill, his desperate quest will end beyond that Door. All he has to do is dare to go through it…
Rye and Sonia have faced the heart-stopping perils of the land behind the golden Door, and the cold terrors that lurk behind the silver Door as well. By a miracle, they have survived them both. But Weld is still under threat, and many questions remain to be answered. Rye knows what he has to do. One Door remains a mystery-the ancient wooden Door that he has been drawn to from the beginning. All he has to do is dare to go through it.
Sonia, Rye and his brothers have survived the perils behind the golden and silver doors, but Weld is still under threat from the skimmers, and the companions must pass through the ancient wooden door in a last, desperate effort to save their world.
A boy faces amnesia as he seeks to end the monstrous threat to his city in this finale to a fantasy trilogy by a New York Times–bestselling author. Three magic Doors are the only way in and out of the walled city of Weld. The golden Door is grand and majestic—a Door for heroes. The silver Door hints at mystery and knowledge—a door for schemers. But the plain wooden Door has always held the most appeal for Rye and his friend Sonia. And now, at last, they have the chance to open it. The city of Weld is under attack by skimmers, flying beasts that terrorize the night. If Rye and Sonia can’t discover the enemy sending the skimmers in time, Weld has no hope. Twice before, Rye and Sonia left Weld on a quest to save it. Twice before, they failed. Now there’s just one Door left—one last chance to save the people of Weld. Rye and Sonia know everything depends on them. But nothing can prepare them for the horror that waits behind the wooden Door. Praise for The Third Door “Readers who have come to love the plucky Rye and determined Sonia will be eager for this story. . . . The plot is tied up in an unexpected but very satisfying way. Fans of Rodda’s Deltora Quest series will be thrilled by the tie-ins here. New fans can enjoy this installment without any prior knowledge of the land of Deltora; though they’ll have a richer experience if they’ve read the first two volumes.” —Booklist
After having rescued his eldest brother Dirk during a perilous voyage beyond the Golden Door, humble-butheroic Rye returns to Weld with Dirk and his friends Sonia and Faene. The Silver Door will lead them to bare, desolate places—the Saltings, the Scour—and strange, often desperate people locked in a struggle for survival. It will provide answers to some mysteries, while also giving them new ones to think about. And it will lead them into terrible danger, as the wider ramifications of Olt’s downfall become clear and an even more dangerous enemy rises to challenge them.
The walled city of Weld is under attack from ferocious flying creatures that raid in the night, bringing death and destruction. The Warden calls for Volunteers to find and destroy the Enemy who is sending the invaders. The heroes of Weld answer the call one by one, never to return. Rye's brothers, Dirk and Sholto, are among the lost, and he must find them.
This textbook presents methodologies and applications associated with multiple criteria decision analysis (MCDA), especially for those students with an interest in industrial engineering. With respect to methodology, the book covers (1) problem structuring methods; (2) methods for ranking multi-dimensional deterministic outcomes including multiattribute value theory, the analytic hierarchy process, the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), and outranking techniques; (3) goal programming,; (4) methods for describing preference structures over single and multi-dimensional probabilistic outcomes (e.g., utility functions); (5) decision trees and influence diagrams; (6) methods for determining input probability distributions for decision trees, influence diagrams, and general simulation models; and (7) the use of simulation modeling for decision analysis. This textbook also offers: · Easy to follow descriptions of how to apply a wide variety of MCDA techniques · Specific examples involving multiple objectives and/or uncertainty/risk of interest to industrial engineers · A section on outranking techniques ; this group of techniques, which is popular in Europe, is very rarely mentioned as a methodology for MCDA in the United States · A chapter on simulation as a useful tool for MCDA, including ranking & selection procedures. Such material is rarely covered in courses in decision analysis · Both material review questions and problems at the end of each chapter . Solutions to the exercises are found in the Solutions Manual which will be provided along with PowerPoint slides for each chapter. The methodologies are demonstrated through the use of applications of interest to industrial engineers, including those involving product mix optimization, supplier selection, distribution center location and transportation planning, resource allocation and scheduling of a medical clinic, staffing of a call center, quality control, project management, production and inventory control,and so on. Specifically, industrial engineering problems are structured as classical problems in multiple criteria decision analysis, and the relevant methodologies are demonstrated.
First published in 1202, Fibonacci’s Liber Abaci was one of the most important books on mathematics in the Middle Ages, introducing Arabic numerals and methods throughout Europe. This is the first translation into a modern European language, of interest not only to historians of science but also to all mathematicians and mathematics teachers interested in the origins of their methods.
Here are his first two explosive neo-noir thrillers, The Chicago Way and The Fifth Floor, together in one eBook, with a bonus excerpt from We All Fall Down, the latest installment, due out in hardcover in summer 2011. See why Michael Harvey’s tough-talking, ex-cop-turned- private investigator Michael Kelly has been called Chicago’s answer to Raymond Chandler. The Chicago Way: PI Michael Kelly—usually persona non grata with law enforcement—is hired by his former partner, John Gibbons, to look into the rape and battery case John was instructed to leave open eight years earlier. The very next day, Kelly finds Gibbons dead. To close both cases, Kelly will have to face the mob, a serial killer, and something rotten behind police lines. The Fifth Floor: When PI Kelly is hired by an girlfriend to trail an abusive husband, he doesn’t expect to stumble across a corpse—and perhaps the answer to one of Chicago’s most enduring mysteries. The ensuing investigation takes Kelly to places he’d rather not go, specifically to City Hall, where he gets embroiled in a scam that stretches from current politics back to the night of Chicago’s Great Fire, to face a killer bent on rewriting history.
