This special issue of the International Scientific Journal of Computing includes a selection of papers presented at the Fourth IEEE International Workshop on Intelligent Data Acquisition and Advanced Computing Systems: Technology and Applications (IDAACS), which was held in Dortmund, Germany, September 6-8th, 2007. The workshop was organized by the Research Institute of Intelligent Computer Systems and the Faculty of Computer Information Technologies, Ternopil National Economic University, Ternopil, Ukraine and co-organized by the University of Applied Sciences and Arts, Fachhochschule Dortmund, Dortmund, Germany.

The IDAACS workshop series is established as a forum for high quality reports on state-of-the-art theory, technology and applications of intelligent data acquisition and advanced computer systems. All these techniques and applications have experienced a rapid expansion in the last few years that resulted in more intelligent, sensitive, and accurate methods of data acquisition and data processing applied to manufacturing process control and inspection, environmental and medical monitoring and diagnostics, as well as intelligent information gathering and analyses for the purpose security and safety.

The IDAACS’07 workshop sessions were organized under the following topic areas: Advanced Instrumentation and Data Acquisition Systems; Intelligent Distributed Systems and Remote Control; Virtual Instrumentation Systems; Advanced and High Performance Computing Systems; Cluster and Grid Technologies, Parallel Software Tools and Environments; Embedded Systems; Artificial Intelligence and Neural Networks for Advanced Data Acquisition and Computing Systems; Advanced Mathematical Methods for Data Acquisition and High Performance Computing; Industrial Signal and Image Processing; Data Analysis and Dynamic Modelling; Intelligent Information and Retrieval Systems; Robotics and Autonomous Systems; Information Computing Systems for Education and Commercial Applications; Bio-Informatics and Homeland Security; Safety, Security and Reliability of Software; Wireless Systems – Special Stream.

The success of IDAACS arises not only from the importance of the topics it focuses on, but also because it has been intended as a forum for establishing scientific contacts between research teams and scientists from different countries. This purpose has become one of the main reasons for the rapid success of IDAACS, as it turns out to be one of the few events in this area of research where the former Eastern and Western European scientists can discuss and exchange ideas and information, allowing them to characterize common and articulated research activities and providing the environment for establishing joint research collaborations. It provides the opportunity to all participants to discuss topics with colleagues from different spheres such as academia, industry, and public and private research institutions.

The papers selected for this special issue reflect the variety of research presented during the workshop. The use of techniques such as neural networks, genetic algorithms, and evolutionary computations have been elaborated in many papers. The following four papers are devoted to Instrumentation and Data Acquisition Systems.

The paper “Low-Cost, Intelligent Data Acquisition System for QCM and Other Resonator- Based Bio- and Chemical Sensors” by S. Yurish describes the data acquisition system for quartz crystal microbalance (QCM) and the other (superficial SAW and bulk acoustic wave) resonator-based chemical and biosensors. The system is based on the novel, modified method of the dependent count and allows to obtain high metrological performances: programmable and constant in all frequency range relative error of measurement up to 0,0005 % (5 ppm); nonredundant, reduced conversion time of measurement and wide frequency range from 0.05 Hz to 9 MHz (144 MHz with prescaling).

The paper “Wireless Data Acquisition System Using Bluetooth Technology for Infrasonic Records” by J. Chilo and T. Lindblad presents the design of a digital wireless data acquisition system using a QF4512 programmable signal converter from Quickfilter Technologies, a MSP430 microcontroller from Texas Instruments and a F2M03GLA Bluetooth module from Free2move for infrasonic records. The digital wireless data acquisition system has passed extensive laboratory and field tests.

The paper “Distributed Real-Time Measurement System Using Time-Triggered Network Approach” by P. Bilski and W. Winiecki presents the results of the examination of the deterministic network used by the distributed virtual instrument. Software technology applied to control measurement data transfer between the real-time components was presented. Configuration of the laboratory test stand, designed to examine deterministic network is described. Results of the research are presented and conclusions, as well as future prospects iterated. The paper “Centralised diagnostics of electronic and electric equipment in vehicles, engine lighting equipment testing” by P. Jezdik and J. Novak deals with the engine lighting equipment testing technique. Both, electronic and electric devices in a vehicle are related to communication control buses. Each device can also be described as an electrical consumer with its typical power consumption characteristics. Hence, the proposed diagnostic method is based on investigating transient profile on power lines of a tested device whilst changing its state from off to on. The short time Fourier transform (STFT) processing is then applied to analyze the gained signal. The analysis results evaluate the condition of the engine lighting equipment.

Advanced computing systems and strategies have traditionally been one of the main pillars on which IDAACS rests and this edition of the conference has continued to clearly reflect this fact.

Four areas have been significant. On the one hand, multi-agent based approaches have been applied by several authors to different problems. An example of this is the paper “Multi-agent Simulation of Attacks and Defense Mechanisms in Computer Networks” by I. Kotenko, which deals with research into the distributed cooperative cyber-defense mechanisms that are set up against network infrastructure-oriented attacks such as Distributed Denial of Service, network worms, and other infestations. The authors combine discrete-event simulation, some concepts from multi-agent approaches and packet-level simulation of network protocols to simulate cyber-attacks and cyberprotection mechanisms. Several methods for counteracting cyber-attacks are explored in this paper through this representation of attacks and defense components as agent teams using a software simulation environment developed by the authors.

Innovative applications of neural networks continue to be the part of the conference and this can be appreciated in the paper “Neural Networks for Artificial Immune Systems: LVQ for Detectors Construction” by S. Bezobrazov and V. Golovko is concerned with a non-standard approach for solving the problem of detecting computer viruses detection problem. The method is based on the application of Artificial Immune Systems (AIS), thus, allowing for the detection of the unknown malicious code. The authors describe a particular model following this approach in which the detectors are represented by Learning Vector Quantization (LVQ) neural networks. Some tests of the model are presented and the results seem quite promising.

Signal and image processing and the computational problems they create have always been important within the scope of IDAACS and the paper “Satellite Image Processing on a Grid-based Platform” by D. Petcu, D. Gorgan, F. Pop, D. Tudor and D. Zaharie is an example of how to deal with data intensive applications. The paper concerns the problem of the computing intensive data processing required for satellite image processing and how this task can be done more bearable through its implementation on a grid-based platform. In fact, the authors implement and test one of these platforms with excellent results.

Finally, the realm of business simulation must not be left out and in this line the paper “Integrated Tool Sets for Business Games and Simulation” by P. J. A. Reusch, E. Bozguney and P. Reusch reviews different methods and tools that are used in business games and simulations. These tools are generally used in an isolated way and the authors propose concepts and tools for their integration focusing on XML-technologies (XML-/SVG-files, topic maps, …) and on mind maps and topic maps.

A newly established part of IDAACS 2007 was the Special Stream Wireless Systems. Wireless Communication and Transmission appearing in different technologies like WLAN, Bluetooth, UWB, GSM/GPRS, UMTS, LTE a.o. is getting more and more important in various fields of applications. In particular data acquisition, location based services and mobile information systems can be mentioned. The special stream Wireless Systems was established as a forum for presenting new research results in these areas. In terms of content the results presented in the streams papers cover a wide range, from technical concepts via methodical approaches and security aspects to usability results and concepts of media production for wireless systems.

In the paper “RSSI-based WLAN indoor positioning used within a digital museum guide” by U. Grossmann, M. Schauch and S. Hakobyan, three methods for positioning a mobile device within a WLAN environment are presented. The authors discuss the accuracy of positioning of the methods and the visualization of spatial user position frequency pattern on the basis of a field trial using a position sensitive museum guide.

The paper “Mobile Robot Localization using WLAN Signal Strength” by C. Rohrig and F. Kunemund shows two methods that estimate the position and the heading of a mobile robot using WLAN RSSI technology. Measured signal strength values of an omnidirectional antenna and a beam antenna are compared with the values of a radio map, in order to estimate the pose of a mobile robot, whereby the directionality of the beam antenna is used to estimate the heading of the robot.

The paper “Communication and Localization for a Cooperative esafety-System” by D. Lill, A. Gutjahr and A. Sikora presents the core concept of a project to enable the future availability of a modular cooperative system that will bring together sensor and communication technologies for all road users (vehicles, motorcycles, bicycles, pedestrians). Legacy detection technologies, such as infrared or radar are enhanced by an RF-based communication.

The paper “Security assessment of IEEE 802.16 (WIMAX) – a short comparison between IEEE 802.16d and 802.16e” by E. Eren deals with some of the basic security features of IEEE 802.16d (Fixed WiMAX). Elements of the security architecture, weaknesses, potential attacks and viable counter measurements are presented. Improvements made by the IEEE 802.16e standard (Mobile WiMAX) compared to Fixed WiMAX are discussed.

The paper “Model-driven clock frequency scaling for control-dominated embedded systems” by Z. Karakehayov presents a combination of models and proofs for optimal power management via clock frequency scaling. The approach is suitable for systems on a chip or microcontrollers, where a processor runs in parallel with embedded peripherals.

The paper “Media Engineering with A Content hub system – generic content transformation for mobile media” by M. A. Herzog and M. Trier introduces the concept of generic content transformation for a variety of input and output channels. Generic content transformation allows for the novel means of accessing assets via compound search algorithms. Results out of the three scenarios of media production including mobile media are presented and discussed.

These papers are just a sample of the presentations and results that were seen at IDAACS 2007. We hope the readers find them interesting, useful and even enjoyable.
