CiteSeerX The Accuracy Of Floating Point Summation CiteSeerX - Document Details (Isaac Councill, Lee Giles): . The usual recursive summation technique is just one of several ways of computing the sum of n floating point numbers. Five summation methods and their variations are analysed here. The accuracy of the methods is compared using rounding error analysis and numerical experiments. Four of the methods are shown to be special cases of a general class of methods, and an error analysis is given for this class. No one method is uniformly more accurate than the others, but some guidelines are given on the choice of method in particular cases. Key words. floating point summation, rounding error analysis, orderings. AMS subject classifications. primary 65G05, secondary 65B10. 1. Introduction. Sums of floating point numbers are ubiquitous in scientific computing. They occur when evaluating inner products, means, variances, norms, and all kinds of nonlinear functions. Although, at first sight, summation might appear to offer little scope for algorithmic ingenuity, the usual "recursive summation... http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.43.3535PlanetMath: summation

Zero Sum (Zero Sight Series, Book 2) by B. Justin ShierAstraeus PressMy name is Dieter Resnick. I was planning to turn eighteen in May, but I don't think I'm gonna make it. I've just been drafted into a war. And this war isn't usual. It's kinda sorta fought with spells. My name is Dieter Resnick.

The Sum of All Fears by Tom ClancyBerkleyA major motion picture starring Ben Affleck, Morgan Freeman, James Cromwell, Alan Bates and Michael Byrne! Peace may finally be at hand in the Middle East—as Deputy Director of the CIA Jack Ryan lays the groundwork for a peace plan that could end centuries of conflict. But ruthless terrorists have a final, desperate card to play: they have their hands on a nuclear weapon and have placed it on American soil in the midst of an escalation in tension with the Soviet Union. The terrorists hope to rekindle cold war animosity and prevent reconciliation between Israelis and Palestinians. With one terrible act, distrust mounts, forces collide, and the floundering U.S. president seems unable to cope with the crisis. With the world on the verge of nuclear disaster, Ryan must frantically seek a solution—before the chiefs of state lose control of themselves and the world.
Once again, Tom Clancy manages to add new twists to the alternate U.S. history he initiated in The Hunt for Red October. In The Sum of All Fears, the center of conflict is the perpetual hot spot the Mideast, where a nuclear weapon falls into the hands of terrorists just as peace seems possible. Clancy realistically paints an almost unthinkable scenario--the bomb is planted on American soil in the midst of an escalation in tension with the Soviet Union; the terrorists hope to rekindle cold war animosity and prevent reconciliation between Israelis and Palestinians. Despite such a dramatic story line, Clancy doesn't neglect the individuals who drive his tale. Jack Ryan's problems are as much domestic as they are part of the international crisis that is the ostensible narrative: National Security Director Elizabeth Elliot has the president's ear, and she has convinced him that Ryan's ethics are questionable. She hints at marital infidelity and an insider-trading scandal. Of course, both accusations are false, but her arguments have enough evidence behind them (e.g. some photographs of an innocent embrace with a friend) to cause a strain in the Ryans' marriage and a flurry of media attention. While "Mr. Clark" tracks the terrorists, he also provides some needed intelligence to heal the Ryan family. The Sum of All Fears is the stuff of nightmares but contains enough verisimilitude to terrify sober minds. Ryan has matured into a complex protagonist as Clancy's writing, too, has matured. Ryan is plagued by stress and self-doubts that test even his dauntless moral compass and make him a more interesting subject for readers' attention. Those fascinated by military hardware, from nuclear submarines to atomic weapons, will find almost enough here to start their own army. And Clancy's understanding of international politics seems chillingly correct. --Patrick O'Kelley Easy Chinese Recipes: Family Favorites From Dim Sum to Kung Pao by Bee Yinn LowTuttle PublishingGrowing up in a Chinese household in Malaysia where cuisine and culture were inseparable, Bee Yinn Low developed a deep love and appreciation for food.

The Sum of My Parts (Kindle Single) by James SanfordAmazon.comIn 2002, at the age of 39, I was a successful journalist and critic when I was diagnosed with testicular cancer, a disease that usually strikes men in their teens and 20s. At first I tried to deny my condition (trying to treat a tumor with hot baths and ice packs). Eventually, I decided I would learn as much about my illness as possible while trying to keep my emotions on hold.

The Sum of All Men (The Runelords, Book One:) by David FarlandTor FantasyThe first book of the saga of The Runelords Young Prince Gaborn Val Orden of Mystarria is traveling in disguise on a journey to ask for the hand of the lovely Princess Iome of Sylvarresta. Armed with his gifts of strength and perception, Prince Gaborn and his warrior bodyguard stop in a local tavern along the way. Immediately, they spot a pair of assassins who have their sights set on Princess Iome's father. As the prince and his bodyguard race to warn the king of this impending danger, they realize that more than the royal family is at risk, the very fate of the Earth is in jeopardy. The Runelords is that rare book that will remind you why you started reading fantasy in the first place. Much of the setting--and even some of the story--is conventional fantasy fare, but David Farland, aside from being a masterful storyteller, has built his world around a complex and thought-provoking social system involving the exchange of "endowments." Attributes such as stamina, grace, and wit are a currency: a vassal may help his lord by endowing him with all of his strength, for instance, and in turn the vassal comes under the lord's care as his "dedicate," too weak to even walk. A Runelord might have hundreds of such endowments, giving him superhuman senses and abilities, but he then must care for the hundreds that he has deprived of strength, or beauty, or sight. Runelords excels because this novel idea is not mere window dressing--Farland uses it to explore fundamental questions of life and morality. The story's hero, the young Runelord Gaborn, struggles to define his role in this "shameful economy" while keeping his commitments to himself, to his people, to the woman he loves, and to the earth itself. We end up asking ourselves the same questions: Should you choose your friends based on insight or virtue? Is it better to be just or good? Competent fantasy lets you escape to adventure in faraway lands, but exceptional fantasy makes sure you have something to think about when you get back. Runelords accomplishes the latter. --Paul Hughes I Know DID Lst SumSimon Spotlight EntertainmentFOR USE IN SCHOOLS AND LIBRARIES ONLY.

Zero Sum Game (Star Trek: Typhon Pact #1) by David MackPocket Books/Star TrekA spy for the Typhon Pact—a new political rival of the Federation—steals the plans for Starfleet’s newest technological advance: the slipstream drive. To stop the Typhon Pact from unlocking the drive’s secrets, Starfleet Intelligence recruits a pair of genetically enhanced agents: Dr. Julian Bashir, of station Deep Space 9, and Sarina Douglas, a woman whose talents Bashir helped bring to fruition, and whom Bashir thinks of as his long-lost true love. Bashir and Douglas are sent to infiltrate the mysterious species known as the Breen, find the hidden slipstream project, and destroy it. Meanwhile, light-years away, Captain Ezri Dax and her crew on the U.S.S. Aventine play a dangerous game of cat and mouse with a Typhon Pact fleet that stands between them and the safe retrieval of Bashir and Douglas from hostile territory. Star Trek: The Next Generation: Greater than the Sum (Star Trek Next Generation (Unnumbered)) by Christopher L. BennettPocket Books/Star TrekThe Starship Rhea has discovered a cluster of carbon planets that seems to be the source of the quantum energies rippling through a section of space. A landing party finds unusual life-forms inhabiting one of the planets. One officer, Lieutenant T'Ryssa Chen -- a half-Vulcan -- makes a tenuous connection with them. But before any progress can be made, the Rhea comes under attack from the Einstein -- a Starfleet vessel now controlled by the Borg. The landing party can only listen in horror as their comrades are assimilated. The Borg descend to the planet, and just as Chen accepts that she will be assimilated, the lieutenant is whisked two thousand light-years away. A quantum slipstream -- instantaneous transportation -- is controlled by these beings in the cluster, and in the heart of the cluster there is now a Borg ship. Cut off from the rest of the Borg collective, the Einstein cannot be allowed to rejoin it. For the sake of humanity, the Borg cannot gain access to quantum slipstream technology. Starfleet Command gives Captain Picard carte blanche: do whatever he must to help the beings in the cluster, and stop the Einstein no matter the cost. |
