| Proteus - Study of System Identification Using Higher-Order Statistics, and Model-Based and Time-Frequency Signal
Processing (Bilateral Franco-Slovenian project) |
| Leader: |
Assoc. Prof. Dr. Damjan Zazula |
| Participants: |
Asst. Prof. Dr. Danilo Korže; Dr. Andrej Šoštaric; Dean Korošec, MSc |
| Project partners: |
Institut de Recheche en Cybernétique de Nantes (Dr. Eric Le
Carpentier) |
| Financed by: |
Partly French Ministry of Higher Education and Science, partly the Ministry of Science and Technology of the Republic of Slovenia |
| Duration: |
Jan. 1996 to Dec. 1998 |
| The duration of the project was three years; it began in 1996. It supported research mobility between the Institut de Recherche en Cybernétique de Nantes, France and the System Software Laboratory at the University of Maribor, Slovenia. Our research in 1997 was focused on the analysis of w-slice system identification based on higher-order statistics, as well as wavelet packets and time-frequency representations. The most important joint achievement in 1997 was the analytical proof of a class of the ARMA systems that cannot be identified by this method. We published three joint papers and visited our French partner eight times, in return we were host to four French researchers. In 1998, we continued system identification using higher-order statistics. Primarily, we verified the efficiency and robustness of these methods versus other approaches; for example, we tested the detection of sine signals buried in noise and proved better outcomes with higher-order statistics than with the Prony and MUSIC algorithm. At the same time we worked on time-scale phase representation implemented to an accurate decomposition of compound signals. Again, we published three conference papers. We visited the French partners seven times, and in return we were host to three French scientists. |

| Co-tutelle - Application of Wavelet Transform and Time-Scale Representations to the Decomposition of Compound
Signals (Franco-Slovenian project of co-supervision for Andrej Šoštaric) |
| Supervisors: |
Assoc. Prof. Dr. Damjan
Zazula, Prof. Dr. Christian Doncarli |
| Candidate: |
Dr. Andrej Šoštaric |
| Financed by: |
Partly French Ministry of
Higher Education and Science, partly the Ministry of Science and
Technology of the Republic of Slovenia |
| Duration: |
Feb. 1996 to Nov. 1998 |
| Co-supervision was initiated by the Proteus project in 1996 and ended in November 1998. The PhD research work of A. Šoštaric was supervised by two professors, one in Nantes, France and the other in Maribor, Slovenia, meaning that the candidate's PhD thesis was validated in both countries simultaneously. The main scientific contributions of his thesis are connected with the decomposition of compound signals. Dr. Šoštaric merged wavelet transform and multimodal parametric search with a peel-off technique into a novel decomposition algorithm called subtractive wavelet transform. Additionally, he improved accuracy and efficiency of this algorithm in time direction by introducing a novel time-scale phase analysis. Both methods were thoroughly tested on synthetic surface EMG signals, whereas the former one was tentatively applied to the real needle and surface EMGs as well. |

| CAssET - Upgrading of Computer-Assisted Exercise
Test (Bilateral Hungarian-Slovenian project) |
| Leader: |
Assoc. Prof. Dr. Damjan Zazula |
| Participants: |
Asst. Prof. Dr. Danilo Korže; Dr. Andrej Šoštaric; Dean Korošec,
MSc; Boris Cigale; Dejan Šen |
| Project partners: |
Institute KFKI of the Hungarian Academy of Science (Prof. Dr. György
Kozmann) and the University of Physical Education in Budapest (Dr. Jószef Laczkó) |
| Financed by: |
Partly Hungarian Ministry of Science, partly the Ministry of Science and Technology of Republic of Slovenia |
| Duration: |
Jan. 1997 to Dec. 1998 |
| This was a two-year project which began in 1997. The basic aim of the project was the mobility of researchers working jointly on project activities. These were based on two program packages: firstly, an automated analysis program for the cardiological exercise test, CardioA, developed at the System Software Laboratory of Maribor, Slovenia, and secondly, the database containing annotated electrocardiograms with 32 thoracic leads, owned by the KFKI Institute in Budapest. In the first year of the project, we established a common platform of computer tools and started investigating procedures that would upgrade the existing CardioA. We measured the sensitivity of the CardioA algorithms applied to the Hungarian base of cardiograms. At the University of Physical Education in Budapest, we started developing a combined system to measure the ECG and the EMG signals simultaneously. These activities were accompanied by visits of groups of researchers, three to Budapest and three to Maribor. In the second year we developed two computer-based diagnostic procedures, one deriving probabilistic criteria for different cardiac diseases encountered in the Hungarian ECG database, and the other implementing the RMS value of a measured surface EMG to estimate the joint rotations during healthy and dystonic human arm movements. Four conference papers were published in 1998 and two visits were paid each to Budapest and to
Maribor. |

| Tempus Grant - Individual Tempus project at the Université de Nantes |
| Leader: |
Asst. Prof. Dr. Danilo Korže |
| Participants: |
Asst. Prof. Dr. Danilo Korže |
| Project partners: |
Asst. Prof. Dr. Claude Martinez, Université de Nantes, Institut Universitaire de
Technologie, Dépt. O.G.P., Nantes (contact person) |
| Financed by: |
European Union |
| Duration: |
2 months |
| The main objective of the individual Tempus project was to get acquainted with the flexible production systems and their management. The project was carried out at the Université de Nantes, Institut Universitaire de
Technologie, Dépt. O.G.P., Nantes, France between August 17 and October 15, 1998. The purpose of the individual Tempus project was to prepare the teaching material for industrial engineering, especially the management of flexible production systems and their simulation and evaluation. The modelling of FMS, especially their simulation on computers, was performed using simulation packages, for example, Arena. During the stay, different lectures were attended, which were given at the department OGP. In addition, students completed practical exercises in classrooms and on computers. The office of the international exchanges was visited, and the possibilities of the student exchange between the IUT Nantes and University of Maribor were discussed. The organisation of the studies, both at the host institution and at the home institution were presented, with special emphasis on introducing the credit system. |
