Research addresses increasingly urgent issue of use, protection and potential abuse of personal data in modern information society. Personal data of individual are stored in electronic form in increasingly simplified and accessible way with the goal to improve society's operational efficiency. That trend also significantly exposes personal data and increases the risk of its' abuse. The goal of this research is to determine legal state of the art in Slovene legislation and to execute empirical analysis and determine actual state, with the application of automated tools, on world wide web. The intention is to identify potential ways to abuse personal data and suggest improvements and other measures to prevent personal data abuse, thereby increasing the confidence of people in information society and use of modern technologies on which the information society is build upon.

The interdisciplinary investigation of computer and internet forensics and law will adress the security of information systems and their forensics and so contribute to further developments in the area of slovene legislation about the computer forensics and the judge adoption and consideration of digital evidences, which were gathered during the investigation process.
The research will primary analyse the present state of the art in the area of digital evidence in solving the computer criminal in Slovenia. In continutation of the project the comparative study of results, methods and best pratice in some european contries will be performed on the area of interest. Some guidelines of the European Union will be studied and the harmony of the present practice with these guidelines will be checked.
In the research the possibilies for usage and verification of tools and procedures will be exposed, which are used in collecting the digital evidences and their improvements, which could contribute to enlarging the percent of successfully considered digital evidences in judicial processes.
From the juristical viewpoint the possibilities to propose some corrections of the present legislation will be studied, so that it could be improved to enable easier put into the force of the digital evidences in judicial process.

A bilateral research project whose aim is computer-based diagnosis of surface electromyograms (SEMG) was approved for the period between October 2005 and October 2007. This project collaboration links four research groups, two from Cyprus (Department of Computer Science, University of Cyprus, and Cyprus Institute for Neurology and Genetics, both in Nicosia) and two from Slovenia (beside the System Sofware Laboratory, there is also a group from the Neurology Department in the Teaching Hospital of Maribor).
In 2006 two visits were made, namely two Slovenian researchers visited Nicosia in September, and three Cyprian researchers visited Maribor in December. Agreement was made with medical partners, how recordings of surface electromyograms included in research will be done. Recordings will be taken with standard 4- or 8-channel recording devices at different levels of isometric muscle contractions. The groups from University of Cyprus and University of Maribor will analyse the recorded data each with its own procedure, namely with statistical and entropy methods.

The System Software Laboratory is an associate partner in the I*PROMS Network of Excellence within the 6th European Framework Programme. The network is managed by the University of Cardiff, Great Britain (Manufacturing Engineering Centre), while it comprises more than 30 partners from 14 European countries. In 2006 we continued the research in the field of intelligent multiagent systems. The results were presented at a web conference, organized by I*PROMS.

This project does not have permanent financial support |
| This is a permanent project, aimed at developing and constructing software tools that will enhance the comprehension of basic scientific fields (such as physics, chemistry or computer science). Special emphasize has been placed on an intuitive approach and computer-assisted learning. In 2006, we developed a special learning system using a haptic device, which is designed for 3D virtual environment movement with sense of touch. For demonstration purpose we prepared the models of ovarian ultrasound images and MR images of knee joint.
In September at the conference ICL 2006, held in Villach, we organized a special section named CoLoS. The conference was attended by Prof. dr. Zvonko Fazarinc, who is one of founders of project CoLoS from Palo Alto, California.

The main objective of the project is to develop a prototype device for reliable and robust identification of clinically important muscle parameters out of non-invasively acquired surface electromyograms (SEMG) only. The project covers all aspects from basic research on compound signal decomposition techniques and SEMG signals, to the design and implementation of SEMG acquisition device. It is also highly multidisciplinary integrating the latest developments in signal processing with the state-of-the-art in neurophysiology.
The main objectives of the project include a) the design and implementation of 2D high-density electrode arrays, suitable for recoding the SEMG signals from different types of muscles, b) the development and implementation of advance procedures for automatic decomposition of SEMG signals into its constituent motor unit action potential trains, c) validation and evaluation of the decomposition techniques on both synthetic and real SEMG signals, recorded in different conditions from different muscles.
The project is expected to provide a novel, non-invasive and powerful tool for basic and applied research and clinical investigations in occupational, sport and rehabilitation medicine, ergonomics and space medicine, to have a high social and economic impact, and to considerably reduce the cost of monitoring the effectiveness of current motor rehabilitation treatments.

A bilateral research project whose aim is computer decomposition of surface electromyograms (SEMG) was approved for the period between 2006 and 2008. In 2006 two visits were made, namely two Slovenian researchers visited Torino in August and in September and two Italian researchers visited Slovenia in December.
During his one month stay in Italy Rok Istenič carried out comprehensive research of activity index, which is computed directly from surface recorded EMG signals and which should be an indicator of muscle force produced at definite muscle contraction. Prof. Damjan Zazula gave three lectures for the postgraduate students at Politecnico di Torino during his visit.
Along the visit of prof. Roberto Merletti and dr. Marco Minetto in Slovenia we organized workshop on diagnosis with needle and decomposed surface EMG which took part at Clinical Center in Ljubljana.

| IMuCoS - Identification of central nervous system muscle control strategies by the means of multichannel surface electromyograms decomposition |

The main objective of this project was to extract the information about the muscle properties and central nervous system (CNS) control strategies out of the surface electromyographic signals. This includes but is not limited to the identification of motor units (MU) activation patterns and strategies used by the CNS to control the muscle as a whole, produce smooth contractions and generate finely tuned forces necessary in everyday tasks.
The project was highly multidisciplinary and integrated the expertise from the fields of electronic engineering, signal processing and neurophysiology. Its major scientific contributions include the development of advanced high-density arrays of surface electrode, compound signal decomposition techniques and non-invasive extraction of motor unit discharge patterns. In the filed of compound signal processing, it was demonstrated that the robust and accurate decomposition of the surface electromyogram (EMG) into the contributions of the individual MUs is possible. From the neurophysiologic point of view, we demonstrated for the first time that the non-invasive assessment of MU interactions is possible. In particular, the synchronizations of MU innervation pulse trains and the common in-phase fluctuations of the MU discharge rates (so called common drive) were investigated. Both phenomena were previously reported on the intramuscular EMG, but their scientific relevance was limited by the number of reconstructed MUs (results of previous studies were typically based on 3 to 5 concurrently active MUs, while in our studies up to 30 concurrently active MUs were identified). The third major project’s contribution tackles the decomposition of dynamic surface EMG signals. Up to 10 concurrently active MUs were identified from slow dynamic contractions of dominant biceps brachii muscle. This represents a major advance of state-of-the-art surface electromyography as up to now no similar results have been reported
