The "Man"and his Machines I hope this book will refresh the memories of the few who were lucky enough to use "laptops" in the early years. Also to spark an interest in a machine which changed the way we live and do business today. I believe this book will be an invaluable aid in furnishing the information required to start a very challenging pursuit of vintage "Laptop" Computers. This could be a fascinating venture which would connect you to our life-changing technological history.

Recently, the emergence of wireless and mobile networks has made possible the admission of electronic commerce to a new application and research subject: mobile commerce, defined as the exchange or buying and selling of commodities, services, or information on the Internet through the use of mobile handheld devices. In just a few years, mobile commerce has emerged from nowhere to become the hottest new trend in business transactions. However, the prosperity and popularity of mobile commerce will be brought to a higher level only if information is securely and safely exchanged among end systems (mobile users and content providers). Advances in Security and Payment Methods for Mobile Commerce includes high-quality research papers and industrial and practice articles in the areas of mobile commerce security and payment from academics and industrialists. It covers research and development results of lasting significance in the theory, design, implementation, analysis, and application of mobile commerce security and payment.

As almost no other technology, embedded systems is an essential element of many innovations in automotive engineering. New functions and improvements of already existing functions, as well as the compliance with traffic regulations and customer requirements, have only become possible by the increasing use of electronic systems, especially in the fields of driving, safety, reliability, and functionality. Along with the functionalities that increase in number and have to cooperate, the complexity of the entire system will increase.

Synergy effects resulting from distributed application functionalities via several electronic control devies, exchanging information through the network brings about more complex system architectures with many different sub-networks, operating with different velocities and different protocol implementations.

To manage the increasing complexity of these systems, a deterministic behaviour of the control units and the communication network must be provided for, in particular when dealing with a distributed functionality.

From Specification to Embedded Systems Application documents recent approaches and results presented at the International Embedded Systems Symposium (IESS 2005), which was held in August 2005 in Manaus (Brazil) and sponsored by the International Federation for Information Processing (IFIP).

The topics which have been chosen for this working conference are very timely: design methodology, modeling, specification, software synthesis, power management, formal verification, testing, network, communication systems, distributed control systems, resource management and special aspects in system design.

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

This book examines the issue of design of fully-integrated frequency synthesizers suitable for system-on-a-chip (SOC) processors. This book takes a more global design perspective in jointly examining the design space at the circuit level as well as at the architectural level. The coverage of the book is comprehensive and includes summary chapters on circuit theory as well as feedback control theory relevant to the operation of phase locked loops (PLLs). On the circuit level, the discussion includes low-voltage analog design in deep submicron digital CMOS processes, effects of supply noise, substrate noise, as well device noise. On the architectural level, the discussion includes PLL analysis using continuous-time as well as discrete-time models, linear and nonlinear effects of PLL performance, and detailed analysis of locking behavior.

The material then develops into detailed circuit and architectural analysis of specific clock generation blocks. This includes circuits and architectures of PLLs with high power supply noise immunity and digital PLL architectures where the loop filter is digitized.

Methods of generating low-spurious sampling clocks for discrete-time analog blocks are then examined. This includes sigma-delta fractional-N PLLs, Direct Digital Synthesis (DDS) techniques and non-conventional uses of PLLs. Design for test (DFT) issues as they arise in PLLs are then discussed. This includes methods of accurately measuring jitter and built-in-self-test (BIST) techniques for PLLs. Finally, clocking issues commonly associated to system-on-a-chip (SOC) designs, such as multiple clock domain interfacing and partitioning, and accurate clock phase generation techniques usingdelay-locked loops (DLLs) are also addressed. The book provides numerous real world applications, as well as practical rules-of-thumb for modern designers to use at the system, architectural, as well as the circuit level. This book is well suited for practitioners as well as graduate level students who wish to learn more about time-domain analysis and design of frequency synthesis techniques.

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.

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.

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%."

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.

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.
