Some of the most challenging problems in science and engineering are being addressed by the integration of computation and science, a research ?eld known as computational science. Computational science plays a vital role in fundamental advances in biology, physics, chemistry, astronomy, and a host of other disciplines. This is through the coordination of computation, data management, access to instrumentation, knowledge synthesis, and the use of new devices. It has an impact on researchers and practitioners in the sciences and beyond. The sheer size of many challenges in computational science dictates the use of supercomputing, parallel and distri- ted processing, grid-based processing, advanced visualization and sophisticated algorithms. At the dawn of the 21st century the series of International Conferences on Computational Science (ICCS) was initiated with a ?rst meeting in May 2001 in San Francisco. The success of that meeting motivated the organization of the - cond meeting held in Amsterdam April 21–24, 2002, where over 500 participants pushed the research ?eld further. The International Conference on Computational Science 2003 (ICCS 2003) is the follow-up to these earlier conferences. ICCS 2003 is unique, in that it was a single event held at two di?erent sites almost opposite each other on the globe – Melbourne, Australia and St. Petersburg, Russian Federation. The conference ran on the same dates at both locations and all the presented work was published in a single set of proceedings, which you hold in your hands right now.

This book is dedicated to the memory of Professor Alessandro (Sandro) D'Atri, who passed away in April 2011. Professor D'Atri started his career as a brilliant scholar interested in theoretical computer science, databases and, more generally information processing systems. He journeyed far in various applications, such as human-computer interaction, human factors, ultimately arriving at business informationsystems and business organisation after more than 20 years of researc hbased on "problem solving". Professor D'Atri pursued the development of an interdisciplinary culture in which social sciences, systems design and human sciences are mutually integrated. Rather than retrospection, this book is aimed to advance in these directions and to stimulate a debate about the potential of design research in the field of informationsystems and organisation studies with an interdisciplinary approach. Each chapter has been selected by the Editorial Board following a double blind peer review process. The general criteria of privileging the variety of topics and the design science orientation and/or empirical works in which a design research approach is adopted to solve various field problems in the management area. In addition several chapters contribute to the meta-discourse on design science research.

The pervasive creation and consumption of content, especially visual content, is ingrained into our modern world. We’re constantly consuming visual media content, in printed form and in digital form, in work and in leisure pursuits. Like our cave– man forefathers, we use pictures to record things which are of importance to us as memory cues for the future, but nowadays we also use pictures and images to document processes; we use them in engineering, in art, in science, in medicine, in entertainment and we also use images in advertising. Moreover, when images are in digital format, either scanned from an analogue format or more often than not born digital, we can use the power of our computing and networking to exploit images to great effect. Most of the technical problems associated with creating, compressing, storing, transmitting, rendering and protecting image data are already solved. We use - cepted standards and have tremendous infrastructure and the only outstanding ch- lenges, apart from managing the scale issues associated with growth, are to do with locating images. That involves analysing them to determine their content, clas- fying them into related groupings, and searching for images. To overcome these challenges we currently rely on image metadata, the description of the images, - ther captured automatically at creation time or manually added afterwards.

Roughly a decade ago, power consumption and heat dissipation concerns forced the semiconductor industry to radically change its course, shifting from sequential to parallel computing. Unfortunately, improving performance of applications has now become much more difficult than in the good old days of frequency scaling. This is also affecting databases and data processing applications in general, and has led to the popularity of so-called data appliances—specialized data processing engines, where software and hardware are sold together in a closed box. Field-programmable gate arrays (FPGAs) increasingly play an important role in such systems. FPGAs are attractive because the performance gains of specialized hardware can be significant, while power consumption is much less than that of commodity processors. On the other hand, FPGAs are way more flexible than hard-wired circuits (ASICs) and can be integrated into complex systems in many different ways, e.g., directly in the network for a high-frequency trading application. This book gives an introduction to FPGA technology targeted at a database audience. In the first few chapters, we explain in detail the inner workings of FPGAs. Then we discuss techniques and design patterns that help mapping algorithms to FPGA hardware so that the inherent parallelism of these devices can be leveraged in an optimal way. Finally, the book will illustrate a number of concrete examples that exploit different advantages of FPGAs for data processing.

Wireless technology and handheld devices are dramatically changing the degrees of interaction throughout the world, further creating a ubiquitous network society. The emergence of advanced wireless telecommunication technologies and devices in today’s society has increased accuracy and access rate, all of which are increasingly essential as the volume of information handled by users expands at an accelerated pace. The requirement for mobility leads to increasing pressure for applications and wireless systems to revolve around the concept of continuous communication with anyone, anywhere, and anytime. With the wireless technology and devices come ?exibility in network design and quicker deployment time. Over the past decades, numerous wireless telecommu- cation topics have received increasing attention from industry professionals, a- demics, and government agencies. Among these topics are the wireless Internet; multimedia; 3G/4G wireless networks and systems; mobile and wireless network security; wireless network modeling, algorithms, and simulation; satellite based s- tems; 802.11x; RFID; and broadband wireless access.
