Zuverlässige Vorhersagen sind doch möglich! Nate Silver ist der heimliche Gewinner der amerikanischen Präsidentschaftswahlen 2012: ein begnadeter Statistiker, als »Prognose-Popstar« und »Wundernerd« weltberühmt geworden. Er hat die Wahlergebnisse aller 50 amerikanischen Bundesstaaten absolut exakt vorausgesagt – doch damit nicht genug: Jetzt zeigt Nate Silver, wie seine Prognosen in Zukunft Terroranschläge, Umweltkatastrophen und Finanzkrisen verhindern sollen. Gelingt ihm die Abschaffung des Zufalls? Warum werden Wettervorhersagen immer besser, während die Terrorattacken vom 11.09.2001 niemand kommen sah? Warum erkennen Ökonomen eine globale Finanzkrise nicht einmal dann, wenn diese bereits begonnen hat? Das Problem ist nicht der Mangel an Informationen, sondern dass wir die verfügbaren Daten nicht richtig deuten. Zuverlässige Prognosen aber würden uns helfen, Zufälle und Ungewissheiten abzuwehren und unser Schicksal selbst zu bestimmen. Nate Silver zeigt, dass und wie das geht. Erstmals wendet er seine Wahrscheinlichkeitsrechnung nicht nur auf Wahlprognosen an, sondern auf die großen Probleme unserer Zeit: die Finanzmärkte, Ratingagenturen, Epidemien, Erdbeben, den Klimawandel, den Terrorismus. In all diesen Fällen gibt es zahlreiche Prognosen von Experten, die er überprüft – und erklärt, warum sie meist falsch sind. Gleichzeitig schildert er, wie es gelingen kann, im Rauschen der Daten die wesentlichen Informationen herauszufiltern. Ein unterhaltsamer und spannender Augenöffner!

Jack Potter puts computer cryptography to work for the highest bidder: sometimes for private corporations, sometimes for the government. Sometimes the work is legal; if not, Jack simply raises his price. But one day, Jack discovers something cloaked in the hiss of background radiation streaming past the Earth from deep space: a message from an alien civilization. One that's eager to do business with humanity -- and its representative. Before he knows it, Jack has entered into a partnership that will open a Pandora's Box of potential profit and loss. The governments, the multinationals, and mysterious players more powerful still, all want a piece of the action -- and they're willing to kill, even wage war, to get it. Now Jack is entangled shifting web of deceit and intrigue in which no one, not even his closest friends, can be trusted. For Earth's cloak-and-dagger business practices are writ large in the heavens...and hostile takeovers are just as common across light years as they are across boardroom tables.

We have some time ago noticed that finding a book dealing with topics in the ad vanced theory and applications of signal detection is not quite an easy matter. This is contrasted with that there are numerous books on the more general subject of de tection and estimation.Frankly, ourexperience and expertise is only on some partial portions of the theory and recent topics of signal detection. This book is therefore meant to include not all the advanced and interesting topics in the theory and appli cations ofsignal detection, butjust onlysome subsets of them: some such important and interesting topics and issues as distributed signal detection and sequential de tection are not considered only due to our limited knowledge and capacity. The goal we have in mind for this book is to present several advanced topics in signal detection theory and thereby help readers gain novel ideas and insights. In this book, we have tried to completely present in a unified way the theme oflocally optimum detection ofsignals in generalized observations. Among our hope is thus that the readers would be able to understand the concepts and fundamentals of a generalized observation model as applied to signal detection problems. This book will also allow the readers, whether they are students, academics, practitioners, or researchers, to have an expanded view on signal detection.

The last research frontier in high frequency electronics lies in the so-called terahertz (or submillimeter wave) regime, between the traditional microwave and the infrared domains. Significant scientific and technical challenges within the terahertz (THz) frequency regime have recently motivated an array of new research activities. During the last few years, major research programs have emerged that are focused on advancing the state of the art in THz frequency electronic technology and on investigating novel applications of THz frequency sensing. This book provides a detailed review of the new THz frequency technological developments that are emerging across a wide spectrum of sensing and technology areas.Volume II presents cutting edge results in two primary areas: (1) research that is attempting to establish THz-frequency sensing as a new characterization tool for chemical, biological and semiconductor materials, and (2) theoretical and experimental efforts to define new device concepts within the ?THz gap?.

A film director is dying of cancer. His greatest film would have told the story of a European village as the last hour of 999 AD approached—bringing Armageddon. Now that story will never be told. But he’s still working it out in his head, making a film that no one will ever see.

Der Gegenentwurf zum unproduktiven Unternehmensalltag Wenn ein Unternehmen erfolgreich sein will, benötigt es angeblich hoch bezahlte Direktoren, lange Meetings, ein großes Werbebudget, Fünfjahrespläne und vor allem ständiges Wachstum. So weit die Theorie. In der Praxis kommen die Software-Unternehmer Jason Fried und David Heinemeier Hansson schon seit 10 Jahren ohne all das aus – und haben Erfolg. Die Autoren repräsentieren eine zukunftsweisende Geschäftskultur, die dabei ist, die alten Konzern-Dinosaurier das Fürchten zu lehren. Smart sind die neuen Unternehmer, beweglich, unprätentiös und technisch auf der Höhe. Arbeit ist für sie kein Selbstzweck, und Lebensqualität gehört ebenso zum Business wie die unvermeidliche menschliche Unzulänglichkeit. Nüchtern und wirksam setzt sich „Rework“ von hochtrabenden Begriffen wie „Reform“ oder „Revolution“ ab. Entstanden ist eine ketzerische „Business-Bibel“, die keine Management-Phrasen herbetet, sondern Mut macht zu echter Eigenständigkeit. Zu Recht schrieb ein Rezensent: „Sie können dieses Buch ignorieren, aber auf eigene Gefahr“.

State-of-the-art JNB and SI Problem-Solving: Theory, Analysis, Methods, and Applications Jitter, noise, and bit error (JNB) and signal integrity (SI) have become today‘s greatest challenges in high-speed digital design. Now, there’s a comprehensive and up-to-date guide to overcoming these challenges, direct from Dr. Mike Peng Li, cochair of the PCI Express jitter standard committee. One of the field’s most respected experts, Li has brought together the latest theory, analysis, methods, and practical applications, demonstrating how to solve difficult JNB and SI problems in both link components and complete systems. Li introduces the fundamental terminology, definitions, and concepts associated with JNB and SI, as well as their sources and root causes. He guides readers from basic math, statistics, circuit and system models all the way through final applications. Emphasizing clock and serial data communications applications, he covers JNB and SI simulation, modeling, diagnostics, debugging, compliance testing, and much more.
