Information Hiding Techniques for Steganography and Digital Watermarking

Auteur: Fabien Petitcolas & Stefan Katzenbeisser

taal: engels

Steganography, a means by which two or more parties may communicate using invisible or subliminal communication, and watermarking, a means of hiding copyright data in images, are becoming necessary components of commercial multimedia applications that are subject to illegal use. This is a comprehensive survey of steganography and watermarking and their application to modern communications and multimedia. It helps the reader to understand steganography, the history of this previously neglected element of cryptography, the hurdles of international law on strong cryptographic techniques, and a description of the methods you can use to hide information in modern media. Included in this discussion is an overview of steganalysis , methods which can be used to break stenographic communication. This resource also includes an introduction to and survey of watermarking methods, and discusses this method's similarities to and differences from steganography. The reader should gain a working knowledge of watermarking's pros and cons, and learn the legal implications of watermarking and copyright issues on the Internet.

Interaction Design

Taal: engels

Auteur: Helen Sharp

The classic text, Interaction Design by Sharp, Preece and Rogers is back in a fantastic new 2nd Edition! New to this edition:* Completely updated to include new chapters on Interfaces, Data Gathering and Data Analysis and Interpretation, the latest information from recent research findings and new examples* Now in full colour* A lively and highly interactive Web site that will enable students to collaborate on experiments, compete in design competitions, collaborate on designs, find resources and communicate with others* A new practical and process-oriented approach showing not just what principals ought to apply, but crucially how they can be applied The best basis around for user-centered interaction design, both as a primer for students as an introduction to the field, and as a resource for research practitioners to fall back on. It should be labelled 'start here'. -Pieter Jan Stappers, ID-StudioLab, Delft University of Technology

Introduction to Robotics

Taal: engels

Auteur: Saeed B. Niku

Niku offers comprehensive, yet concise coverage of robotics that will appeal to engineers. Robotic applications are drawn from a wide variety of fields. Emphasis is placed on design along with analysis and modeling. Kinematics and dynamics are covered extensively in an accessible style. Vision systems are discussed in detail, which is a cutting-edge area in robotics. Engineers will also find a running design project that reinforces the concepts by having them apply what they've learned.

Just Enough Software Architecture

Auteur: George Fairbanks

Taal: engels

This practical guide seeks to make architecture relevant to all software developers. Developers need to understand how to use constraints as guiderails that ensure desired outcomes, and how seemingly small changes can affect a system's properties.
It teaches risk-driven architecting. There is no need for meticulous designs when risks are small, nor any excuse for sloppy designs when risks threaten your success. This book describes a way to do just enough architecture. It avoids the one-size-fits-all process tar pit with advice on how to tune your design effort based on the risks you face.

It democratizes architecture. This book seeks to make architecture relevant to all software developers. Developers need to understand how to use constraints as guiderails that ensure desired outcomes, and how seemingly small changes can affect a system's properties.

It cultivates declarative knowledge. There is a difference between being able to hit a ball and knowing why you are able to hit it, what psychologists refer to as procedural knowledge versus declarative knowledge. This book will make you more aware of what you have been doing and provide names for the concepts.

It emphasizes the engineering. This book focuses on the technical parts of software development and what developers do to ensure the system works — not job titles or processes. It shows you how to build models and analyze architectures so that you can make principled design tradeoffs. It describes the techniques software designers use to reason about medium to large sized problems and points out where you can learn specialized techniques in more detail.

It provides practical advice. Software design decisions influence the architecture and vice versa. The approach in this book embraces drill-down/pop-up behavior by describing models that have various levels of abstraction, from architecture to data structure design.

Kosmologie

Auteur: Coles

Wat gebeurde er tijdens de Oerknal? Hoe kwamen sterrenstelsel tot stand? Gaat er de uitdijing van het heelal steeds sneller? Wat is 'donkere materie'? Hoe ontstaan rimpelingen in de microgolfachtergrondstraling? Dit is het soort vragen die de kosmologen van vandaag trachten te beantwoorden. Dit boek is een toegankelijk en niet-technische introductie in de geschiedenis van de kosmologie en de laatste ontwikkelingen op dat terrein. Een ideaal beginpunt voor eenieder die nieuwsgierig is naar het heelal en hoe het allemaal begon.

Liefde voor leren

over diversiteit van leren en ontwikkelen in en van organisaties

Auteur: M. Ruijters

Liefde voor leren komt de eigen ontwikkeling en die van organisaties ten goede. Mensen die van leren houden staan positief ten opzichte van nieuwe denkbeelden en inzichten, nieuwe situaties en ontwikkelingen. Daarbij leren ze op verschillende manieren en hebben voorkeuren voor verschillende contexten. In de manier waarop leren nu vaak georganiseerd wordt, zien we die diversiteit niet terug. Uitgangspunten als: leren kan alleen in een veilige omgeving, nieuw gedrag leer je alleen door te oefenen, lijken waarheden. Maar is dat nou wel zo?Dit boek laat zien dat een bepaalde aanpak op een bepaalde plek en bij bepaalde mensen heel goed werkt, maar op een ander moment en bij andere mensen totaal niet! Als organisatie wil je meekomen in een zich snel ontwikkelende maatschappij met mensen die zich volledig ontplooien. Dit betekent met meer liefde, openheid en respect naar leren kijken en vervolgens het leren licht en transparant organiseren in en om het werk. In Liefde voor ontwikkelt Manon Ruijters een 'taal' die diversiteit in leren benoemt en weg wijst bij het vormgeven van leren op individueel, groeps-en organisatieniveau.

Lone Survivors

Auteur: Chris Stringer

Taal: engels

A LEADING RESEARCHER ON HUMAN EVOLUTION PROPOSES A NEW AND CONTROVERSIAL THEORY OF HOW OUR SPECIES CAME TO BE.

In Lone Survivors, the world-renowned paleoan-thropologist Chris Stringer puts forward a radi-cal new theory of humanity's origin. Drawing on previously unavailable archaeological and genetic evidence, he argues that Homo sapiens did not origi-nate in a single region of Africa. Instead, different populations coexisted across the continent with other species like HOMO erectus, exchanging genes, tools, and behavioral and survival strategies before some of them migrated into Europe and beyond. Eventually, Homo sapiens replaced all other human species.

Stringer describes how advances in modern sci-ence have had a huge impact on our understanding of man's origins, and how newly available analysis has shown that the appearance of modern humans was not inevitable, but was the result of successes, failures, luck, diet, and climatic changes. In Dar-win's time, there was little fossil evidence at all, but today it is possible to map the genre of a Nean-derthal and scan hominid fossils down to the width of a single cell. New techniques from radiocarbon dating to satellite images can unlock remarkable evolutionary insights from fossils, measure historic temperature fluctuations in Greenland ice, and dis-cover huge river channels beneath the desert sands. In exploring the different aspects of the the-ory, Stringer addresses some of the most intrigu-ing questions about mankind's past: What forces shaped the origin of modern humans? What do the genetic data really tell us about our origins? What drove modern humans to migrate from Africa? How much of our modern behavior was shared by earlier human species? Is the evolution of modern humans complete, and are we the finished product? Lone Survivors is the definitive account of who and what we were and will change perceptions about our origins and about what it means to be human.
