"An exploration of depictions and use of water within Renaissance Italy, and especially in the work of polymath Leonardo da Vinci. Both a practical necessity and a powerful symbol, water presents one of the most challenging problems in visual art due to its formlessness, clarity, and mutability. In Renaissance Italy, it was a nearly inexhaustible subject of inquiry for artists, engineers, and architects alike: it represented an element to be productively harnessed and a force of untamed nature. Watermarks places the depiction and use of water within an intellectual history of early modern Italy, examining the parallel technological and aesthetic challenges of mastering water and the scientific and artistic practices that emerged in response to them. Focusing primarily on the wide-ranging work of Leonardo da Vinci (1452-1519)-at once an artist, scientist, and inventor-Leslie Geddes shows how the deployment of artistic media, such as ink and watercolor, closely correlated with the engineering challenges of controlling water in the natural world. For da Vinci and his peers, she argues, drawing was an essential form of visual thinking. Geddes analyses a wide range of da Vinci's subject matter, including machine drawings, water management schemes, and depictions of the natural landscape, and demonstrates how drawing-as an intellectual practice, a form of scientific investigation, and a visual representation-constituted a distinct mode of problem solving integral to his understanding of the natural environment. Throughout, Geddes draws important connections between works by da Vinci that have long been overlooked, the artistic and engineering practices of his day, and critical questions about the nature of seeing and depicting the almost unseeable during the early modern period"--

Watermarking techniques involve the concealment of information withina text or images and the transmission of this information to thereceiver with minimum distortion. This is a very new area ofresearch. The techniques will have a significant effect on defence, business, copyright protection and other fields where informationneeds to be protected at all costs from attackers.This book presents the recent advances in the theory andimplementation of watermarking techniques. It brings together, for thefirst time, the successful applications of intelligent paradigms(including comparisons with conventional methods) in many areas. Theaccompanying CD-Rom provides readers with source codes and executablesto put into practice general topics in watermarking

From Christy Ann Conlin, the critically acclaimed and award winning author of Heave, comes a breathtaking and unforgettable collection about how the briefest moment can shape us forever. In these evocative and startling stories, we meet people navigating the elemental forces of love, life, and death. An insomniac on Halifax’s moonlit streets. A runaway bride. A young woman accused of a brutal murder. A man who must live in exile if he is to live at all. A woman coming to terms with her eccentric childhood in a cult on the Bay of Fundy shore. A master of North Atlantic Gothic, Christy Ann Conlin expertly navigates our conflicting self-perceptions, especially in moments of crisis. She illuminates the personality of land and ocean, charts the pull of the past on the present, and reveals the wildness inside each of us. These stories offer a gallery of both gritty and lyrical portraits, each unmasking the myth and mystery of the everyday.

We are happy to present to you the proceedings of the 2nd International Workshop on Digital Watermarking, IWDW 2003. Since its modern re-appearance in the academic community in the early 1990s, great progress has been made in understanding both the capabilities and the weaknesses of digital watermarking. On the theoretical side, we all are now well aware of the fact that digital waterma- ing is best viewed as a form of communication using side information. In the case of digital watermarking the side information in question is the document to be wat- marked. This insight has led to a better understanding of the limits of the capacity and robustness of digital watermarking algorithms. It has also led to new and improved watermarking algorithms, both in terms of capacity and imperceptibility. Similarly, the role of human perception, and models thereof, has been greatly enhanced in the study and design of digital watermarking algorithms and systems. On the practical side, applications of watermarking are not yet abundant. The original euphoria on the role of digital watermarking in copy protection and copyright prot- tion has not resulted in widespread usage in practical systems. With hindsight, a n- ber of reasons can be given for this lack of practical applications.

Digital audio, video, images, and documents are flying through cyberspace to their respective owners. Unfortunately, along the way, individuals may choose to intervene and take this content for themselves. Digital watermarking and steganography technology greatly reduces the instances of this by limiting or eliminating the ability of third parties to decipher the content that he has taken. The many techiniques of digital watermarking (embedding a code) and steganography (hiding information) continue to evolve as applications that necessitate them do the same. The authors of this second edition provide an update on the framework for applying these techniques that they provided researchers and professionals in the first well-received edition. Steganography and steganalysis (the art of detecting hidden information) have been added to a robust treatment of digital watermarking, as many in each field research and deal with the other. New material includes watermarking with side information, QIM, and dirty-paper codes. The revision and inclusion of new material by these influential authors has created a must-own book for anyone in this profession. This new edition now contains essential information on steganalysis and steganography New concepts and new applications including QIM introduced Digital watermark embedding is given a complete update with new processes and applications

The 1st International Workshop on Digital Watermarking (IWDW), the con- rence covering all aspects of digital watermarking, was held at the Hotel Riviera situated along the beautiful Han River in Seoul, Korea from November 21 to 22, 2002. These proceedings contain 21 papers that were accepted for presentation at the conference. These papers were selected from 67 submissions including 3 invited papers. They went through a thorough review process by the Program Committee and were selected on the basis of excellence and novelty. The following is a brief description of the history of this conference and - viewing process: In August 2001 some members of the Special Interest Group on Multimedia Protection (SIGMP) of the Korea Institute of Information Security and Cryptology (KIISC) agreed to create the IWDW. In November 2001 we set up a Program Committee and solicited papers while asking Springer-Verlag to publish the proceedings of the workshop in their Lecture Notes in Computer Science series. In July 2002 we received 64 submissions from 14 countries using Microsoft’s conference management site (http://cmt. research. microsoft. com/ iwdw2002/). Each submission was assigned a number automatically by the c- ference management tool and the paper was sent to the Program Committee members for their review. We also encouraged di?erent sets of experts to join for fair reviews.

Teresa Mandrell’s first encounter with advertising executive Rayann Germaine begins badly and goes downhill from there. Within minutes of their meeting, Rayann dubs Teresa a ” bumbling amateur” . The event changes the course of Teresa’s life—she abandons the corporate world for what she hopes is a more satisfying career in Fine Arts Management. When budget cuts leave her without work, Teresa gets a job as a design artist in another firm, only to discover that the new department head is…Rayann! But the difference in the woman’s demeanor is so startling that Teresa can’t believe her eyes. Although the woman she’d fought with had been insensitive and rude, she was full of fire and passion. This Rayann is cold and withdrawn. To Teresa’s chagrin, the woman doesn’t even remember their fight. In fact, the two fall easily into an increasingly harmonious work relationship. As they grow even closer, Teresa slowly uncovers layer after layer of Rayann’s hurt and pain. When she at last arrives at the terrible truth, Teresa is left with one burning question: How can she turn Rayann’s heart away from grief and lead her back toward life and love? Watermark is the heartbreaking and heartmending sequel to Touchwood.
