Refereed post-proceedings of the First International Workshop on Data Management in Grids, in Trondheim, Norway. The 11 papers in this book address current research activities in relation to data management in dynamic, heterogeneous and cross-organizational environments, or grids. They show expertise in the management of very large, widely distributed databases. Conversely, Grids offer a novel and exciting field of research for database scientists in application domains and for fundamental research.

We are delighted to welcome readers to the proceedings of the 6th Pacific-Rim Conference on Multimedia (PCM). The first PCM was held in Sydney, Australia, in 2000. Since then, it has been hosted successfully by Beijing, China, in 2001, Hsinchu, Taiwan, in 2002, Singapore in 2003, and Tokyo, Japan, in 2004, and finally Jeju, one of the most beautiful and fantastic islands in Korea. This year, we accepted 181 papers out of 570 submissions including regular and special session papers. The acceptance rate of 32% indicates our commitment to ensuring a very high-quality conference. This would not be possible without the full support of the excellent Technical Committee and anonymous reviewers that provided timely and insightful reviews. We would therefore like to thank the Program Committee and all reviewers. The program of this year reflects the current interests of the PCM s. The accepted papers cover a range of topics, including, all aspects of multimedia, both technical and artistic perspectives and both theoretical and practical issues. The PCM 2005 program covers tutorial sessions and plenary lectures as well as regular presentations in three tracks of oral sessions and a poster session in a single track. We have tried to expand the scope of PCM to the artistic papers which need not to be strictly technical."

First of all, we appreciate the hard work of all the authors who contributed to ICEC 2005 by submitting their papers. ICEC 2005 attracted 95 technical paper submissions, 8 poster submissions and 7 demo submissions, in total 110. This number is nearly equal to ICEC 2004. Based on a thorough review and selection process carried out by 76 international experts from academia and industry as members of the senior and international program committees, a high-quality program was compiled. The program committee consisted of experts from all over the world: 1 from Austria, 3 from Bulgaria, 2 from Canada, 4 from China, 1 from Finland, 4 from France, 10 from Germany, 1 from Greece, 1 from Ireland, 1 from Israel, 1 from Italy, 26 from Japan, 1 from Korea, 4 from The Netherlands, 1 from New Zealand, 1 from Norway, 1 from Singapore, 1 from Thailand, 4 from the UK, and 8 from the USA. In this number, reviewers are included. The final decision was made at the senior program committee meeting based on three reviewers' feedback, available online via the conference management tool. Through earnest and fair discussion at the meeting, 25 technical papers were accepted as long papers and 32 technical papers were accepted as short papers from 95 submitted technical papers. Moreover, 3 poster papers and 5 demo papers were accepted.

We welcome you to the proceedings of IWQoS 2005 held at the University of Passau, in the beautiful state of Bavaria, Germany. We hope that all attendees enjoyed their time in that ancient and historic city. Quality of Service(QoS) continues to be an important area of research. T- ditionally very focused on the area of networking, it has grown to include mobile applications, wireless environments, 3G and 4G cellular networks, user expe- ence, overlay networks, large-scale systemsand other important areas ofappli- tion. Six full-paper sessions that comprised selected papers of very high quality were devoted to the above mentioned, cutting-edge topics in this volume. We had a fascinating cross-disciplinary program and hope to have seeded conn- tions between di?erent disciplines and between industry and academia. In addition to the reviewed paper sessions, we were pleased to present two inspiring keynote speakers in this year's program: Randy Katz, Universityof California, Berkeley, USA, and Michael Stal, SiemensAG, Munich, Germany. One speaker being from academia and one from industry, re?ected well the balanced view of this workshop. Both keynotes extended the scope of QoS and addressed pressing issues, such as "spam," and leading trends, such as "service orientation," and their relevance to QoS.

Over the last few years Web Engineering has begun to gain mainstream acc- tance within the software engineering, IT and related disciplines. In particular, both researchers and practitioners are increasingly recognizing the unique c- racteristics of Web systems, and what these characteristicsimply in terms of the approaches we take to Web systems development and deployment in practice. A scan of the publications in related conference proceedings and journals highlights the diversity of the discipline areas which contribute to both the ri- ness and the complexity of Web Engineering. The 5th International Conference on Web Engineering (ICWE2005), held in Sydney, Australia, extends the traditions established by the earlier conferences in the series: ICWE2004 in Munich, Germany; ICWE2003 in Oviedo, Spain; ICWE2002 in Santa Fe, Argentina; and ICWE2001 in Caceres, Spain. Not only have these conferences helped disseminate cutting edge research within the ?eld of Web Engineering, but they have also helped de?ne and shape the discipline itself.TheprogramwehaveputtogetherforICWE2005continuesthisevolution. Indeed, we can now begin to see the maturing of the ?eld. For possibly the ?rst time, there was very little debate within the Program Committee about which papers were in and out of scope, and much more debate as to the each papers contributions to the ?eld."

The papers are organized in topical sections on biometric recognition, multimedia content security, steganography, watermarking, authentication, classification for biometric recognition, digital watermarking, content analysis and representation, 3D object retrieval and classification, representation, analysis and retrieval in cultural heritage, content representation, indexing and retrieval, content analysis and classification, feature extraction and classification, multimodal signal processing, 3D video and free viewpoint video, multimedia content transmission and classification, video and image processing, as well as video analysis and representation.

Around the world, tourists are drawn to visit murals painted on walls. Whether heritage asset, legacy leftover, or contested art space, the mural is more than a simple tourist attraction or accidental aspect of tourism material culture. They express something about the politics, heritage and identity of the locations being visited, whether a medieval fresco in an Italian church, or modern political art found in Belfast or Tehran. This interdisciplinary and highly international book explores tourism around murals that are either evolving or have transitioned as instruments of politics, heritage and identity. It explores the diverse messaging of these murals: their production, interpretation, marketing and - in some cases - destruction. It argues that the mural is more than a simple tourist attraction or accidental aspect of tourism material culture. Murals and Tourism will be valuable reading for those interested in cultural geography, tourism, heritage studies and the visual arts.

This book constitutes the refereed proceedings of the 6th International Symposium on Smart Graphics, SG 2006, held in Vancouver, Canada, July 2006.

Welcome to Santiago de Compostela! We are pleased to host the 27th Annual EuropeanConferenceonInformationRetrievalResearch(ECIR2005)onits?rst visit to Spain. These proceedings contain the refereed full papers and poster abstracts p- sented at ECIR 2005. This conference was initially established by the Infor- tion Retrieval Specialist Group of the British Computer Society (BCS-IRSG) under the name "Annual Colloquium on Information Retrieval Research. " The colloquium was held in the United Kingdom each year until 1998, when the event was organized in Grenoble, France. Since then the conference venue has alternated between the United Kingdom and Continental Europe, re?ecting the growing European orientation of ECIR. For the same reason, in 2001 the event was renamed "European Conference on Information Retrieval Research. " In - cent years, ECIR has continued to grow and has become the major European forum for the discussion of research in the ?eld of information retrieval. ECIR 2005 was held at the Technical School of Engineering of the University of Santiago de Compostela, Spain. In terms of submissions, ECIR 2005 was a record-breaking success, since 124 full papers were submitted in response to the call for papers. This was a sharp increase from the 101 submissions received for ECIR 2003, which was the most successful ECIR in terms of submissions. ECIR 2005 established also a call for posters, and 41 posters where submitted. Paper and poster submissions were received from across Europe and further a?eld, including North America, South America, Asia and Australia, which is a clear indicationofthegrowingpopularityandreputationoftheconference.

We are happy to present to you the proceedings of the 3rd International Workshop on Digital Watermarking, IWDW 2004. Since its modern reappearance 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 watermarking 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 watermarked. 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 protection has not resulted in widespread use in practical systems. With hindsight, a number of reasons can be given for this lack of practical applications.

This volume contains the ?nal proceedings for the 2004Computer Music Mod- ing and Retrieval Symposium (CMMR 2004). This event was held during 26-29 May 2004 in Esbjerg, Denmark on the joint campus area of Aalborg University Esbjerg and the University of Southern Denmark, Esbjerg. CMMR is an annual event focusing on important aspects of computer music. CMMR 2004 is the s- ond event in this series. CMMR 2003, which was held in Montpellier, France in May 2003, was a great success and attracted high-quality papers and prominent researchers from the ?eld of computer music. The CMMR 2003 postsymposium proceedingswaspublishedbySpringerintheLectureNotesinComputerScience series (LNCS 2771). CMMR 2004 was jointly organized by Aalborg University Esbjerg in Denmark and LMA, CNRS, Marseille in France (in cooperation with ACM SIGWEB). The use of computers in music is well established. CMMR 2004 provided a unique opportunity to meet and interact with peers concerned with the cro- in?uence of the technological and creative in computer music. The ?eld of c- putermusicisinterdisciplinarybynatureandcloselyrelatedtoanumberofc- puter science and engineering areas such as information retrieval, programming, human computer interaction,digital libraries,hypermedia, arti? cialintelligence, acoustics, signal processing, etc. The event gathered many interesting people (researchers, educators, composers, performers, and others). There were many high-qualitykeynoteandpaperpresentations,thatfosteredinspiringdiscussions. I hope that you ?nd the work presented in these proceedings as interesting and exciting as I have.

From November 30 to December 2, 2005, INTETAIN 2005 was held in beautiful Madonna di Campiglio, on the majestic mountains of the Province of Trento, Italy.The ideato holdthe?rstinternationalconferencethat wouldhaveas topic Intelligent Technologies for Interactive Entertainment seemed to be timely. In thepreviouscoupleofyearstherehadbeenothermorespeci?c ormoregeneric events where some of the relevant themes had made it to the front stage. With INTETAIN we were aiming at establishing a conference where intelligent computational technologies are at the basis of any interactive application for entertainment. As intelligent computational technologies we mean adaptive media pres- tations, recommendation systems in media scalable crossmedia, a?ective user interfaces, intelligent speech interfaces, tele-presence in entertainment, colla- rative user models and group behavior, collaborative and virtual environments, crossdomain user models, animation and virtual characters, holographic int- faces, augmented, virtual and mixed reality, computer graphics and multimedia, pervasive multimedia, creative language environments, computational humor, and so on. We also believe that there is an important role for novel underlying inter- tive device technologies, for example, mobile devices, home entertainment c- ters, haptic devices, wallscreendisplays, holographicdisplays, distributed smart sensors, immersive screens and wearable devices. Interactive applications for entertainment include, but are certainly not l- ited to, intelligent interactive games, intelligent music systems, interactive c- ema, edutainment, interactive art, interactive museum guides, city and tourism explorer assistants, shopping assistants, interactive real TV, interactive social networks, interactive storytelling, personal diaries, websites and blogs, and c- prehensive assisting environments for special groups (challenged, children, the elderly)."

Focusing on the manipulation and representation of geometrical objects, this book explores the application of geometry to computer graphics and computer-aided design (CAD). Over 300 exercises are included, some new to this edition, and many of which encourage the reader to implement the techniques and algorithms discussed through the use of a computer package with graphing and computer algebra capabilities. A dedicated website also offers further resources and useful links.

It is an honor and great pleasure to write a preface for this postproceedings of the 6th International Workshop on Information Hiding. In the past 10 years, the field of data hiding has been maturing and expanding, gradually establishing its place as an active interdisciplinary research area uniquely combining information theory, cryptology, and signal processing. This year, the workshop was followed by the Privacy Enhancing Technologies workshop (PET) hosted at the same location. Delegates viewed this connection as fruitful as it gave both communities a convenient opportunity to interact. We would like to thank all authors who submitted their work for consideration. Out of the 70 submisions received by the program committee, 25 papers were accepted for publication based on their novelty, originality, and scientific merit. We strived to achieve a balanced exposition of papers that would represent many different aspects of information hiding. All papers were divided into eight sessions: digital media watermarking, steganalysis, digital forensics, steganography, software watermarking, security and privacy, anonymity, and data hiding in unusual content. This year, the workshop included a one-hour rump session that offered an opportunity to the delegates to share their work in progress and other brief but interesting contributions.

Many animators and designers would like to supplement their Maya learning with a less-technical, more helpful book. This new self-study manual is both a general guide for understanding 3-D computer graphics and a specific guide for learning the fundamentals of Maya: workspace, modeling, animation, shading, lighting, and rendering.

This well-integrated and produced volume covers these fundamentals in each chapter so that readers gain increasingly detailed knowledge. After an initial 'concepts' section launches each chapter, hands-on tutorials are provided, as well as a chapter project that progressively adds newly learned material and culminates in the final animated short. This is the first book on Maya that teaches the subject using a sensible, proven methodology for both novices and intermediate users.

Topics and features: * Proven method that emphasizes preliminaries to every chapter * Integrates the "why" concepts of 3-D simultaneously with the "how-to" techniques * Skills reinforced with tutorials and chapter projects * Real-world experience distilled into helpful hints and step-by-step guides for common tasks * CD-ROM with practice animations, case studies and additional methods

The book, suitable for novices or intermediate users, presents all the basic 3-D animation concepts and Maya software background needed for learning animation techniques and creating sophisticated, state-of-the-art animations. It is an essential resource for animators, game developers, effects specialists, and computer graphic artists, as well as an ideal self-study guide for students or individuals pursuing interests in graphics or animation.

Augmented and virtual reality are media innovations with specific characteristics. They create immersion in the user, as the user is immersed in the medium and its 360 Degrees environment. To successfully develop content and applications for AR and VR, psychological effects, the specifics of the 360 Degrees environment, the story, and the way the media is used must be aligned with the needs and experiences of the user. Content producers face novel challenges in content development, method selection, teamwork, and the overall production process of AR and VR experiences. The book introduces readers to the characteristics of immersive media and provides scientific evidence and practical tips to help them produce high-quality, user-centric content for immersive media. The scientifically derived success factors in the form of checklists are a guide and an ideal basis for standardizing the production process and further developing one's own projects.This book is a translation of the original German 1st edition Medieninnovationen AR und VR by Elle Langer, published by Springer-Verlag GmbH Germany, part of Springer Nature in 2020. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.

The study reported in this paper is an ongoing effort. We reported a preliminary analysis of the data in the paper. The current experiments varied the subjects to c- duct online group learning activities by the communication media such as email and threaded discussion. Although, we could have easily learned the impact of mobile devices in learning if we divided the subjects to use different hardware such as p- sonal computers, personal digital assistant, or mobile phones, we believe our findings will still be able to provide useful insights on the difficulties that the mobile learners will face in solving problems as a group. Our analysis result will also provide ba- line information on whether the traits of the successful or failed online groups are applicable to the mobile learners. For example, we expect the SMS will be a better medium to overcome the major problem of instant communication or the rapid propagation of the information as the mobile phones have built-in mechanism to remind the users of the incoming new messages and also the mobile phone users are expected to be interrupted for the incoming messages. However, we need further investigation of other problems, which hinder the optimum online group work. For example, 'accuracy of the transferred information' was identified as one of the pr- lems of using emails as the communication medium. Personal Digital Assistant (PDA) or SMS are more apt to deliver shorter messages than the typical emails.
