On behalf of the Organizing Committee for Pervasive 2008, welcome to the proceedings of the 6th International Conference on Pervasive Computing. The year2008wasthesecondtimeinasmanyyearsthatthePervasiveconferencehas attempted to "globalize" For the second year in a row the conference was held outside of Europe. The conference is seen as one of the most respected venues for publishing researchon pervasive and ubiquitous computing and captures the state of the art in pervasive computing research. In 2008, as in previous years, the proceedings present solutions for challenging research problems and help to identify upcoming research opportunities. Pervasive 2008 attracted 114 high-quality submissions, from which the Te- nical Program Committee accepted 18 papers, resulting in a competitive 15. 8% acceptance rate. There were over 335 individual authors from 27 countries, c- ing from a wide range of disciplines and from both academic and industrial organizations. Papers were selected solely on the quality of their peer reviews using a double-blind review process. The review process was carried out by 38 members of the international Technical ProgramCommittee (TPC) who are - perts of international standing. The TPC members were aided by 104 external reviewers. It wasa rigorousreviewprocess, in whicheachpaper had atleastfour reviews: three reviews provided by by the Committee members and one review written by an external reviewer. The reviews were followed by a substantive - liberation on each paper during an electronic discussion phase before the start of the Committee meeting.

Embedded and ubiquitous computing systems have considerably increased their scope of application over the past few years, and they now also include missi- and business-critical scenarios. The advances call for a variety of compelling - sues, including dependability, real-time, quality-of-service, autonomy, resource constraints, seamless interaction, middleware support, modeling, veri?cation, validation, etc. The International Workshop on Software Technologies for Future Embedded and Ubiquitous Systems (SEUS) brings together experts in the ?eld of emb- ded and ubiquitous computing systems with the aim of exchanging ideas and advancing the state of the art about the above-mentioned issues. I was honored to chair the sixth edition of the workshop, which continued the tradition of past editions with high-quality research results. I was particularly pleased to host the workshop in the wonderful scenario of Capri, with its stunning views and traditions. The workshop started in 2003 as an IEEE event, and then in 2007 it became a ?agship event of the IFIP Working Group 10.2 on embedded systems. The last few editions, held in Hakodate (Japan), Vienna (Austria), Seattle (USA), Gyeongju (Korea), and Santorini (Greece), were co-located with the IEEE - ternationalSymposiumonObject/Component/Service-OrientedReal-TimeD- tributed Computing (ISORC). This year, SEUS was held as a stand-alone event for the ?rst time, and, - spite the additionalorganizationaldi?culties, it resultedina high-qualityevent, with papers from four continents (from USA, Europe, East Asia and Australia), (co-) authored and presented from senior scientists coming from academia or leading industrial research centers.

Informatics Education - Supporting Computational Thinking contains papers presented at the Third International Conference on Informatics in Secondary Schools - Evolution and Perspective, ISSEP 2008, held in July 2008 in Torun, Poland. As with the proceedings of the two previous ISSEP conferences (2005 in Klag- furt, Austria, and 2006 in Vilnius, Lithuania), the papers presented in this volume address issues of informatics education transcending national boundaries and, the- fore, transcending differences in the various national legislation and organization of the educational system. Observing these issues, one might notice a trend. The p- ceedings of the First ISSEP were termed From Computer Literacy to Informatics F- damentals [1]. There, broad room was given to general education in ICT. The ECDL, the European Computer Driving License, propagated since the late 1990s, had pe- trated school at this time already on a broad scale and teachers, parents, as well as pupils were rather happy with this situation. Teachers had material that had a clear scope, was relatively easy to teach, and especially easy to examine. Parents had the assurance that their children learn "modern and relevant stuff," and for kids the c- puter was sufficiently modern so that anything that had to do with computers was c- sidered to be attractive. Moreover, the difficulties of programming marking the early days of informatics education in school seemed no longer relevant. Some colleagues had a more distant vision though.

The Internet has now become an integral part of everyday life for hundreds of millions of people around the world. The uses of the Internet have augmented commerce, communication, education, governance, entertainment, health care, etc. E-mail has become an indispensable part of life; the Web has become an indispensable source of information on just about everything; people now use governmentWebsitestoreceiveinstructionsandinformation, and?lepaperwork with the government; many major online businesses have been created, such as Amazon, eBay, Google, Travelocity, eTrade, etc. However, the uses of the Internet have also had serious negative e?ects, - cluding spam, the spreading of viruses and worms, spyware, phishing, hacking, online fraud, invasions of privacy, etc. Viruses and worms often bring down tens of millions of computers around the world; many people get duped into furni- ing their personal identi?cations, and bank and insurance account information, etc.; hackers break into government and corporation computers to steal cri- cal data; unsubstantiated rumors about individuals or organizations spread like wild?re on the Internet, etc. Further, the uses of the Internet are creating new paradigms in areas such as copyright, governance, etc. The widespread use of peer-to-peer ?le sharing systems, started by Napster, is forcing a reassessment of the value of holding copyright on digital media. Internet postings by vocal citizens to the Web sites of the news media, governmento?ces, and elected g- ernment o?cials are impacting government policies and swaying the opinions of other citizens. The aim of the International Conference on Human

Welcome to the 3rd International Conference on Wired/Wireless Internet C- munications (WWIC). After a successful start in Las Vegas and a selective c- ference in Germany, this year s WWIC demonstrated the event s maturity. The conference was supported by several sponsors, both international and local, and became the o?cial venue for COST Action 290. That said, WWIC has now been established as a top-quality conference to promote research on the convergence of wired and wireless networks. This year we received 117 submissions, which allowed us to organize an - citing program with excellent research results, but required more e?ort from the 54 members of the international Program Committee and the 51 additional reviewers. For each of the 117 submitted papers we asked three independent - viewers to provide their evaluation. Based on an online ballot phase and a TPC meeting organized in Colmar (France), we selected 34 high-quality papers for presentation at the conference. Thus, the acceptance rate for this year was 29%."

Welcome to the proceedings of UbiComp 2004. In recent years the ubiquitous computing community has witnessed a sign- cant growth in the number of conferences in the area, each with its own disti- tive characteristics. For UbiComp these characteristics have always included a high-quality technical program and associated demonstrations and posters that cover the full range of research being carried out under the umbrella of ubiq- tous computing. Ours is a broaddiscipline andUbiComp aims to be aninclusive forum that welcomes submissions from researchers with many di?erent ba- grounds. This year we received 145 submissions. Of these we accepted 26, an acceptance rate of just under 18%. Of course acceptance rate is simply a m- sure of selectivity rather than quality and we were particularly pleased this year to note that we had a large number of high-quality submissions from which to assemble the program for 2004. The broad nature of ubiquitous computing research makes reviewing Ubi- Comp submissions a particular challenge. This year we adopted a new process for review and selection that has, we hope, resulted in all authors obtaining - tremely detailed feedback on their submission whether or not it was accepted for publication. We believe the process enabled us to assemble the best pos- ble program for delegates at the conference. If you submitted a paper, we hope that you bene?ted from the feedback that your peers have provided, and if you attended UbiComp 2004 we hope that you enjoyed the technical program.

The Information Society is bringing about radical changes in the way people work and interact with each other and with information. In contrast to previous information processing paradigms, where the vast majority of computer-mediated tasks were business-oriented and executed by office workers using the personal computer in its various forms (i. e. , initially alphanumeric terminals and later on graphical user interfaces), the Information Society signifies a growth not only in the range and scope of the tasks, but also in the way in which they are carried out and experienced. To address the resulting dimensions of diversity, the notion of universal access is critically important. Universal access implies the accessibility and usability of Information Society technologies by anyone, anywhere, anytime. Universal access aims to enable equitable access and active participation of potentially all citizens in existing and emerging computer-mediated human activities by developing universally accessible and usable products and services, which are capable of accommodating individual user requirements in different contexts of use and independently of location, target machine, or run-time environment. In the context of the emerging Information Society, universal access becomes predominantly an issue of design, pointing to the compelling need for devising systematic and cost-effective approaches to designing systems that accommodate the requirements of the widest possible range of end-users. Recent developments have emphasized the need to consolidate progress by means of establishing a common vocabulary and a code of design practice, which addresses the specific challenges posed by universal access.

Here is a one-volume guide to just about everything computer-related for amateur astronomers

Today's amateur astronomy is inextricably linked to personal computers. Computer-controlled "go-to" telescopes are inexpensive. CCD and webcam imaging make intensive use of the technology for capturing and processing images. Planetarium software provides information and an easy interface for telescopes. The Internet offers links to other astronomers, information, and software. The list goes on and on.

Find out here how to choose the best planetarium program: are commercial versions really better than freeware? Learn how to optimise a go-to telescope, or connect it to a lap-top. Discover how to choose the best webcam and use it with your telescope. Create a mosaic of the Moon, or high-resolution images of the planets...

Astronomy with a Home Computer is designed for every amateur astronomer who owns a home computer, whether it is running Microsoft Windows, Mac O/S or Linux. It doesn't matter what kind of telescope you own either - a small refractor is just as useful as a big "go-to" SCT for most of the projects in this book.

Twenty years ago, informatics was introduced as a compulsory subject in A- trian secondary schools. During this period informatics has experienced drastic evolutions and even some shifts of paradigms. This applies to an even larger extent to the didactics of informatics. ISSEP-InformaticsinSecondarySchools,EvolutionandPerspectives-takes stock of how the developments in the ?eld are re?ected in school throughout Europe. Teachersofinformaticsatsecondaryschoolsaswellaseducatorsofsuch teachers propose innovative methods of instruction, discuss the scope of overall informaticsinstruction,anddiscusshowinnovativeconceptscanbedisseminated to students in education as well as to active informatics teachers. Duetothepenetrationofinformationtechnologyintosocietyatlargeandinto schools in particular, the relationship between informatics and education leading togeneralcomputerliteracyortotheuseofIT-basedapproachesinconventional subjects, e-learning in school, is an evident focus of many contributions. According to the broad scope of the conference its proceedings are split into two volumes. This volume, From Computer Literacy to Informatics Fundam- tals, covers papers reporting on national strategies of informatics instruction and their evolution in accordance with the penetration of information proce- ing equipment in our daily life. In one way or another, these strategies strive to accommodate the needs of basic skills in information and communication te- nology (ICT) with educational principles that can be conveyed by informatics instruction in a traditional sense. Hence, the papers on national strategies are complementedintwoways:?rstly,bycontributionsthatstrivetoidentifyfun- mental issues, informatics can contribute to the general education process of the youth; and, secondly, by papers presenting approaches on how to link or even to combine instruction about such informatics fundamentals with the need to introduce pupils to the productive use of ICT.

Context-awareness is one of the drivers of the ubiquitous computing paradigm. Well-designed context modeling and context retrieval approaches are key p- requisites in any context-aware system. Location is one of the primary aspects of all major context models - together with time, identity and activity. From the technical side, sensing, fusing and distributing location and other context information is as important as providing context-awareness to applications and services in pervasive systems. Thematerialsummarizedinthisvolumewasselectedforthe1stInternational Workshop on Location- and Context-Awareness (LoCA 2005) held in coope- tion with the 3rd International Conference on Pervasive Computing 2005. The workshop was organized by the Institute of Communications and Navigation of the German Aerospace Center (DLR) in Oberpfa?enhofen, and the Mobile and Distributed Systems Group of the University of Munich. During the workshop, novel positioning algorithms and location sensing te- niques were discussed, comprising not only enhancements of singular systems, like positioning in GSM or WLAN, but also hybrid technologies, such as the integration of global satellite systems with inertial positioning. Furthermore, - provements in sensor technology, as well as the integration and fusion of sensors, were addressed both on a theoretical and on an implementation level. Personal and con?dential data, such as location data of users, have p- found implications for personal information privacy. Thus privacy protection, privacy-oriented location-aware systems, and how privacy a?ects the feasibility and usefulness of systems were also addressed in the workshop.

UbiComp 2003, the 5th Annual Conference on Ubiquitous Computing, is the premier forum for presentation of research results in all areas relating to the - sign, implementation, deployment and evaluation of ubiquitous computing te- nologies. The conference brings together leading researchers, from a variety of disciplines, perspectives and geographical areas, who are exploring the impli- tions of computing as it moves beyond the desktop and becomes increasingly interwoven into the fabrics of our lives. This volume, the conference proceedings, contains the entire collection of high-quality full papers and technical notes from UbiComp 2003. There were 16 full papers in this year's conference, selected by our international program committee from among 117 submissions. There were also 11 technical notes in the program: 8 taken from the 36 technical note submissions, and 3 that were adapted from full paper submissions. We are very grateful to Tim Kindberg and Bernt Schiele, our Technical Notes Co-chairs, and to all the authors and reviewers of both papers and technical notes who contributed to maintaining the high standards of quality for the conference. In addition to the full papers and technical notes, UbiComp 2003 also p- vided a number of other participation categories, including workshops, dem- strations, interactive posters, a panel, a doctoral colloquium and a video p- gram. While accepted submissions in these categories were also of high quality, timing and size constraints prevented us from including them in this volume.
