Activity progress report



MTA SZTAKI was fulfilling its tasks basically as much as possible

according to the submitted plans and to the accepted contract version. We

invited, selected and hosted foreign research experts to work with our

colleagues on various themes related to our activities. We had the chance to

visit other institutions and deepen our co-operation with international scientific

partners. We have been vary active in international co-operation, and thanks to

the prestigious title of Centre of Excellence, we had achieved nice results in

research and in forming joint activities, preparing joint proposals, etc.

3 professors continued to work overlapping the previous and present

reporting periods, two visitors started and ended their work within this period,

and additional 2 professors just arrived by the end of February.

We have planned, organised, prepared and conducted several workshops

and conferences. They were successful both for us, organisers, and also for all

participants. Our Institute‟s national and international appreciation has been

risen by these actions. We are proud to have organised a very successful IFIP

Conference (PROLAMAT) and participated at the e+e Thematic Exhibition

for Automation and Control instruments.

According to the plans, our laboratories utilised the previously

purchased durable equipment (hardware and software) in order to meet the

requirements of research co-operation envisaged.

Just to list briefly some figures:

4 significant science books were published by authors of our Institute, on

Cellular Neural Networks, visual computing, Process modelling and model

analysis, Intelligent control systems, On non-linear systems with varying

structures..

7 books have been edited by SZTAKI researchers, and the long list of

cca.270 publications are given in the attachment. Out of this number, 57

appeared in international journals, 69 within international co-operation. Almost

120 oral, conference presentations were carried out. 7 new Ph.D. degrees were

granted and 2 titles for Doctor of Academy were received. 53 scientists had

taken part in lecturing at university courses. Almost 30 projects had been

contracted and being worked on within the 5th Framework.

Project Management and co-ordination





 Objectives and planned actions:

The objectives were to direct and co-ordinate all activities to successfully

meet the goals of the Centre. From the beginning of the past year, all our

actions have been influenced by the general and specific aims of the EU,

through the Centre of Excellence programme.

 Problems encountered:

Some visitors, who agreed to join our institute, had to postpone or had to

cancel their visit. The 11th of September had a very strong negative effect on

business travels, and research topics and priorities were altered.

 Results:

We have defined the specific financial processes and their handling

mechanism for all foreseen CoE activities.



 Publications and papers:

We have participated in training courses and workshops for promoting

EU5th Framework actions, and on preparing proposals. Several scientific

papers were prepared and submitted.

Workpackage progress report for Workpackage No.: B



Exploitation and dissemination, twinning and

multimedia/videoconferencing system to support co-operation





 Objectives and planned actions:

The objectives are to make the best use of the visiting scientists‟ stay, and to

gain benefits from their visits. By implementing video-conferencing and

new equipment for multimedia, we planned to introduce the most up-to-date

technology for assisting these activities.

.

 Problems encountered:



 Results:

We have implemented a video-conferencing environment for accessing

international channels with high bandwidth. We organised and participated

in several video-conferencing events, and invited industrial partners to join

us within those events. .

We are constantly documenting our scientific events on digital media, and

the slides, photos and video-recordings are archived.

We have prepared posters and slide-shows for demonstrating our Centre of

Excellence at numerous exhibitions, at universities when trying to attract

young undergraduates and postgraduates for research employment.

Under twinning activities, our efforts in joint research within the ERCIM

Consortium is the most important. At the top level, the directors‟ board of

ERCIM gives twice a year a forum to make substantial decisions on future

actions. Our institute has to be represented by the director, by the

vice-director and the senior scientist responsible for the ERCIM Newsletter

and other specific matters. These are the General meeting.

In addition , there are the Execom - executive committee – meetings, and

the special Working Group Meetings, where our institute‟s experts are

required to participate.



 Publications and papers:

The results are displayed on the web by each Laboratory and Department

carrying out the tasks. In the attachment, the full list of our publications is

included.

Workpackage progress report for Workpackage No.: C





Foreign visitors at the SZTAKI, virtual laboratories





 Objectives and planned actions:

The objectives are to invite foreign experts, and make their visits useful both

for them and for the hosting partners. Five professors started their work and

two professors concluded their visits, but three professors have carried on

overlapping the reporting periods. The first visiting professors have their

reports annexed to this periodic report.

3 professors, who had started their visit previously, had concluded their

work: Dr. H. Hjalmarsson visited us from Stockholm, Dr. D. Stokits from

Bremen and R.A. Sheidl came from Vienna. Though their preliminary report

had also been shown in the first six-month CoE report, we attach their

summaries again. 2 new scientists started and concluded their visit and work:

Ulrich Meyer and Alexandru Popa PhD. candidates joined 2 of our

laboratories and their reports are attached.

Further actions were taken in building virtual labs. A good progress had been

achieved with the Laboratory at Stuttgart, with a University department at

Minho, Portugal and at a Sofia-Rennes joint department.

.

 Problems encountered:

It was a problem to re-invite visiting scientists. It takes a rather long time

(might take a year) for persons to schedule a long research visit at any place,

not just at SZTAKI.

 Results:

We have opened the invitation and advertised it to many partner institutions.

We clarified the workplan with those we had selected for acceptance.

At the beginning and at the end of the visits we organised open seminars,

inviting our academic and industrial partners as well, to take part in the

meetings

We have prepared posters and slide-shows for demonstrating our Centre of

Excellence at several exhibitions, universities when trying to attract young

undergraduates and postgraduates for research employment.



Regarding the establishment of virtual laboratories, the RENED initiative

was established between MTA SZTAKI (HU), INSA Rennes(F), TU Sofia

(BG), ICMET and TU Craiova (RO), TU Kharkiv and Tavrichestiy National





5

University (Ukr) in the filed of IT.

The VIMINS initiative for virtual institutes/laboratories had its technical

meeting in January, in Budapest.



The visiting scientists have their reports at the annex of this periodic report.



2 professors have just arrived to work with us at the end of February 2002.



 Publications and papers:

2 joint papers had been prepared and been submitted and accepted for

international conferences -by the visiting scientists.

Workpackage progress report for Workpackage No.: D





Organising Workshops, Conferences and Scientific Meetings





 Objectives and planned actions:

The driving force for this workpackage is to enable the widespread

dissemination of the ideas, theories, methods and technologies. We had

planned a large number of activities like this in most technical

workpackages.

.

 Problems encountered:

The conferences and workshops we listed in the original proposal were

already completed by the time we received the signed contract.

The Conferences had suffered from the effects of 11. September, as many

participants had cancelled their business travel.



 Results:

We had an international Scientific IFIP Conference, PROLAMAT: with a

great success. The proceedings had been printed by Kluwer academic Press.

A Workshop for international PhD. students were organised on System

modelling and identification.



 Publications and papers:

Books, preprints, proceedings, and other documents related to our scientific

events are available. Most of the events are stored on videotapes as well, and

there were many pictures taken for electronic, multimedia reuse. The

presentations are done in Microsoft PowerPoint slides, and these files are

stored for later re-use.

Workpackage progress report for Workpackage No.: E





Visits to another research centre





 Objectives and planned actions:

The objective was to share the ideas and research results with colleagues

around Europe. For deeper and longer consultations, it is not enough to

utilise video-conferencing, but personal visits are needed.

Visits in this period: The director and a deputy-director of the SZTAKI took

part in the ERCIM top-level Conferences. ERCIM is the European Research

Fora for our several prioritised scientific main interest , and hence our

institute must establish a strong working relation with other ERCIM

members.

 Many colleagues, had chance to visit conferences, or EU universities and

research places for shorter or longer periods, but their financing was not

based on the Centre of Excellence funds.

 A preparation session for a joint research project proposal (Acronym STAR)

had been organised by the University of Bucharest, and our Institute had

taken an active role in it. A 3 day short working visit was managed in

December to attend the Bucharest working session.

 Dr.Dmitri Chetverikov visited the Machine Intelligence Research amd

Application Centre for Learning Excellence, (MIRACLE) in Orague,

between September and November.

.

 Problems encountered:

Several long-term visits were planned, but till now not all have been realised,

due to changes in the starting time. Short visits are very often taken for most

of the Laboratories, to widen the co-operation and run joint projects, but the

needs for the trips come up very rapidly, and thus they cannot be planned

long ahead.



 Results:

Intense activity exists between our Institute and other institutes.



Some members of our Laboratories are often invited by foreign partners to

join for preparing new project proposals.

Report on the Visit of Expert Dr. Dragan Stokic

at the Computer and Automation Research Institute, Hungarian Academy

of Sciences, MTA SZTAKI, as a Centre of Excellence titled by the EU

according to the EU contract ICAI-CT-2000-70025



Period: 20.08.2001 - 02.10.2001





Report done by: Dr. Dragan Stokic







October, 2001





1. Introduction

1.1. Background

Dr. Stokic was invited to visit the Computer and Automation Research Institute, Hungarian

Academy of Sciences, MTA SZTAKI, as a Centre of Excellence, by Dr. George L. KOVÁCS,

Head of the CIM Research Laboratory at SZTAKI. During the last few years SZTAKI and ATB

(Institute for Applied System Technology Bremen, Germany) have established a co-operation

and information exchange. Currently they jointly run, together with other partners, the IST

project REDEST, on requirements engineering for embedded software.

The visit was prepared by Prof. George Kovács and Mr. Géza Haidegger.

Mr. Stokic spent 6 weeks at SZTAKI , from 20.08.2001up to 02.10.2001.

1.2. Goal of the report

The goals of this report are:

- to present the work done in the scope of Mr. Stokic‟ visit

- to indicate the main results of the visit

- to present future plans for co-operation between SZTAKI and ATB

to evaluate the visit and summarise the main lessons learnt



2. Objectives of the visits

The objectives of the visit were:

- to learn and to understand the local/national solutions, requirements, specific needs,

- to benefit the scientific progress of SZTAKI,

- to implement prospective, new disciplines at SZTAKI

- to influence the birth of joint research and development results,

- to generate new research and development ideas and projects,

- to prepare new research proposals, especially for submission to the EU under the 5th and the

following Framework Programmes,

- to help in the dissemination of the results,





10

- to take part in the preparation of referenced, cited publications,

- to deliver scientific, technical presentations.

In doing this Mr Stokic was obliged to act according to the rules of the EU, in specific to accept

the terms of the EU‟s Centre-of-Excellence Contract with SZTAKI.



3.Task Execution

The plan to achieve these objectives was defined in agreement between Dr. Stokic and

representatives of SZTAKI Prof. Kovács and Mr. Haidegger (see Appendix).

The work was carried out to a large extent according to this plan:

 Dr Stokic got acquainted with the technical environment at SZTAKI and with the help of

(junior) employees of CIM Research Laboratory has used it for his work

 Using written material (reports, publication, etc.) provided by the host and based on

discussions with Dr. Peter Inzelt, Director of SZTAKI, Prof. Kovács and Mr. Haidegger

and other researchers at the Laboratory, Dr Stokic learnt about the organisational structure,

current research topics and the projects running at SZTAKI, specifically on themes and

projects addressed by the CIM Research Laboratory.

 He learnt about the local/national solutions, requirements, and specific needs based on

discussions with experts at SZTAKI, as well as based on direct contacts and discussions

with experts from several Hungarian companies: LANEX, RADAINT, INDUSTRIEPLAN

etc.

 On 23. August, 2001 Dr Stokic made an initial presentation on the expertise and research

themes, specifically on knowledge management, Internet based solutions for tele-working

and on SW engineering themes.

 Several discussions on common research subjects with experts at SZTAKI were carried

out, and based on these discussions, a set of common research themes and specific projects

were defined.

 The common proposals to be prepared for submission to the EU under the 5th and the

following, 6th Framework Programme were elaborated where Dr. Stokic played an active

role in contacting the Hungarian industrial partners and defining their interest and roles in

the future projects.

 Dr Stokic particularly got acquainted with the SZTAKI‟s current EU project XPERTS by

participating in the general meeting and visit to the Hungarian industrial partner MECOF.

 Discussions on possible common publications within the common RTD activities were

carried out.

 The ideas for future co-operation were discussed with several experts from SZTAKI.

 The strategy to help in the dissemination of the results of different projects was elaborated

as well.

 On 2. October, 2001 a short presentation of the results of common work during the visit and

discussion on the plans for future co-operation was made.



4. Main results

The main results of the visits can be summarised as follows:

- Mr. Stokic learnt the main Hungarian national approaches in the organisation of the

research area, including the main funding schemes and rules. He got acquainted with the

main technical subjects addressed by SZTAKI and specifically by CIM Research

Laboratory.

- Collaboration between SZTAKI (CIM Research Laboratory) and ATB on several RTD

themes was agreed upon: knowledge management, BEP (Best Enterprise Practice)





11

approaches, and software engineering.

- Based on discussions, the CIM Research Laboratory decided to enter in the area of BEP

approaches to support SMES (Small and Medium Enterprises) specifically in the area of

new collaboration models among SMEs in the recycling domain and in the area of

knowledge based systems for after sales support.

- Two common proposals for the October IST call were prepared: one supporting

introduction of new organisation forms and corresponding IST solutions at SMEs in the

recycling domain and one on the supporting SMEs in introducing Internet knowledge based

systems for solving customers and production problems.

- Co-operation on the knowledge management RTD topics will be established specifically

over collaboration between the XPERTS project in which SZTAKI is taking part and the

PICK project in which ATB is acting as the RTD partner.

- Co-operation on the advanced approaches to support after sale services is agreed upon as

well.

- Further co-operation on SW engineering themes will be carried out in the scope of the

common REDEST project, and common publications and dissemination activities are

defined.

- Possibilities to establish Virtual Laboratory between ATB and SZTAKI are defined. The

idea is to provide complementarity in expertise between two sides. They will be established

in the first place in the scope of knowledge management issues where possibilities to

introduce SZTAKI experts in the current ATB projects is likely to be realised in the near

future.

-

5. Future Plans

The long-term activities on future collaboration include:

- Further projects, especially common proposals in the frame of the next (last) Calls in the 5th

Framework Programme, as well as preparation for the common proposal in the 6 th

Framework Programme. The collaboration within the Best Practice networks and the

networks of expertise on knowledge management will be established.

- Further exchange of visits of experts between ATB and SZTAKI, specifically the visits of

experts from SZTAKI to ATB-Bremen within the current and future joint projects are

planned.

- Continuous exchange on the research results will be established by a regular exchange of

publications, as well as by preparation of common publications.

-

6. Conclusions and Lessons Learnt

It can be summarised as follows:

- The visit was very useful for both Dr. Stokic and his Institute (ATB-Bremen) and SZTAKI

to ensure their further co-operation.

- The experts at SZTAKI have openly presented all their results and enabled the visitor to

fully get acquainted with the current practice at the Institute and to learn about the main

RTD results.

- The conditions provided by SZTAKI (organisation of the visit, accommodation etc.,) were

excellent.

- The technical infrastructure provided at SZTAKI is optimal for visits like this.

Based on the experience gained during this visit and the results achieved, it can be concluded as

follows:

- Visits like this appear to be very useful for establishing tight collaborations among RTD

organisations in Europe.





12

- It would be useful to make visits in both directions possible within the CEO, i.e., to provide

support for the experts from the Enlargement countries to visit organisations in the EU in

order to further support co-operation between European organisations.

- A higher flexibility in planning the visits could be beneficial; since periods of 6 weeks are

relatively long for any expert to be away from his offices,. Allowing breaking the visits into

two or more shorter periods would be useful.

Introduction

This is a brief report of my visit to the Computer and Automation Institute of the Hungarian Academy of Sciences

(MTA SZTAKI) during the period 2001-08-20 --- 09-30. The initiative of this visit was taken by my host Dr

Laszlo Gerencser, Head of the Stochastic Systems Group.

The visit was sponsored by MTA SZTAKI as part of their EU Center of Excellence activities. This support is

gratefully acknowledged.



Interaction at the Institute

During my visit I had the opportunity to present two seminars at the institute. In one seminar I presented my home

department and in particular our activities in Micro Electro Mechanical Systems (MEMS) which has bearings on

the activities in the Analogical and Neural Computing Laboratory at the institute. In the other seminar I focused

more on the activities in my own group, and in particular my own work on controller tuning.

I also had some interesting discussions with Professor Josef Bokor which revealed that we have common research

interests in the area of identification of nonlinear systems which deserves further exploration.

Most of my time was spent with Dr Laszlo Gerencser, Head of the Stochastic Systems Group. For a number of

years I have been working on a controller tuning method known as Iterative Feedback Tuning (IFT). In parallell,

Professor Gerencser has been contributing to the development of a stochastic approximation method known as

Simultaneous Perturbation Stochastic Approximation (SPSA), Recently he and his co-workers have shown that the

randomization method on which SPSA is based has some very interesting convergence properties when applied to

noise free problems. One purpose of my visit was to explore if these ideas also could be adapted to IFT and what

randomization in general has to offer for control problems. This visit also gave us the opportunity to explore what

other research interests we have in common. A significant part of my visit was spent on discussions with Professor

Gerencser on possible future joint projects.



Scientific work

Although much of my time was devoted to discussions with Professor Gerencser on possible future research

projects, we early on decided that it was important that the visit also resulted in some hard results. During the visit,

we did joint work in three different areas:

 Randomization in Iterative Feedback Tuning.

As mentioned earlier, one purpose of my visit was to explore if randomization algorithms can be combined with

IFT. This work resulted in the paper ``Randomized Iterative Feedback Tuning'', L. Gerencser, Z. Vago and H.

Hjalmarsson which has been submitted to the 2002 IFAC World Congress.



 Experiment Design.

Since a couple of years I have been active in experiment design for system identification by way of a PhD project.

We have been able to develop an experiment design procedure which can be stated as a convex optimization

problem. However, the problem remained that the cost function depends on the unknown system. During my visit

at SZTAKI this obstacle was passed and a procedure was developed where the system is recursively identified and

the experiment design successively adapted. The method is asymptotically optimal, i.e. it performs as





15

well as if the true system was known. A manuscript to be submitted to Automatica is in preparation.



 Iterative Learning Control (ILC).

ILC is a method which can be used to generate a suitable feedforward control for systems where the same

trajectory is taken over and over again. This input is generated by a series of experiments where the feedforward

input is successively improved. Convergence and optimality of these iterations has previously been proved for

noise free systems. During my visit we developed a Stochastic Approximation version of the algorithm which

converges also under noisy conditions. A manuscript to be submitted to Automatica is in preparation.



Future collaboration

The competencies of the Stochastic Systems Group at SZTAKI and the Automatic Control Group at KTH are to a

large extent complementary. This lead to the contributions in the areas mentioned above, i.e. randomization in

Iterative Feedback Tuning, experiment design and iterative learning control. It is thus very natural to continue and

extend the collaboration on these subjects and other topics involving control and stochastics. There also seems to

be a potential for a joint collaboration between the Stochastic Systems Group, the Systems and Control Laboratory

and the Automatic Control Group at KTH in the area of non-linear (stochastic) systems.



Possible frameworks for this is the ERCIM (The European Research Consortium for Informatics and

Mathematics) Working Group of Control and Systems where SZTAKI is participating and ERNSI (the European

Research Network on System Identification) where KTH is participating.

An interesting idea would be joint supervision of PhD students. However, presently there seems to be some

practical problems, especially related to the funding system at KTH.



Concluding remarks

I would like to conclude this report with some personal remarks. I found the visit at SZTAKI very fruitful and most

enjoyable and a number of people contributed to this. The resources and support at the institute were exemplary

and in particular I am very grateful to Mr Geza Haidegger for all help regarding administrative matters.

Finally, very special thanks to Laszlo and Zsusanna for your hospitality and the enormous time you spent with me

on research problems and all extracurricular activities that you arranged (not to mention your effort spent on

translating an uncountable number of Hungarian menus for me).

Thanks guys!

Operngasse 22

A-1040 Wien

T: +43-1-5812730

M: 0664-1547588

E: roland@alton.at







Objectives of the Visit



The goals of the visit were to get more projects to SZTAKI and to help in the dissemination of

results of common research areas.





Tasks of the Visit



First of all, Mr Alton-Scheidl has given insight of his activities and his expertise and could learn

from the Department of Distributed Systems their research agenda. He has written project

proposals and lead the negotiation for getting SZTAKI on board of EC funded projects.

Furthermore, he learned specific local needs for disseminating research results on e-Democracy

software.





Results of the Visit



Mr Alton-Scheidl started his visit at the Department of Distributed Systems, Computer and

Automation Research Institute, Hungarian Academy of Sciences end of July 2001. At his first

day, he has given a speech to the staff of the department with a focus on his work and the goals

of his visit. With several meetings with staff members he worked out a weighted platform

technology comparison for groupware based applications in order to build future projects on a

solid basis. The final decision was made at the beginning of October for using php based open

source solutions.







17

In August, Mr Alton-Scheidl has started negotiations with the EDEN consortium

(www.edentool.org), in order to make a NAS proposal. He has worked out the proposal and

sent it to consortium members. SZTAKI should become a partner of the EDEN consortium in

2Qu02.



In parallel, we have worked out a new IST proposal called "PublicVoiceXML", which has been

submitted on-time on the 17th of October. In this consortium, SZTAKI has the role of a

technical supplier and will bring its know-how with XML solutions. The project is expected to

start on March 1st, 2002.



During the visit period at SZTAKI, a number of negotiation steps have been carried out to allow

a smooth project start for StreamOnTheFly on January 1st 2002, with SZTAKI being a cluster

partner.



Future Plans



Mr Alton-Scheidl will be working together with SZTAKI until end of 2003 due to 3

international projects in which he is involved as a consultant of the Austrian partner PUBLIC

VOICE Lab. Within those projects, he will meet staff from SZTAKI regularly every 2-3 months

and will follow-up common tasks.



Together with SZTAKI's deputy director for research he will be active in the 6th framework

planning process. Mr Alton-Scheidl is a delegate in the national advisory committee for the 6th

framework programme in Austria and will use the knowledge to set up Expression of Interests

and a Network of Excellence.



Mr Alton-Scheidl agreed with SZTAKI, that there will be mutual support for getting SZTAKI

and PUBLIC VOICE Lab into 6th framework consortia.





Conclusions



Mr Alton-Scheidl did benefit of the nice infrastructure and the good personal relations between

the team members and is looking forward to continue collaboration with the department in three

R&D projects, for which the contractual arrangements have been prepared during his visit. The

Center of Excellence status allowed him to work on international joint projects with SZTAKI.

Work Report



Ulrich Meyer

Max-Planck Institute for Computer Science,

Saarbruecken, Germany



Guest at MTA SZTAKI during Jan/Feb 2002

Following the accepted work plan, I conducted research and gave lectures on graph-traversal

problems for large data sets In an introduction lecture for the research group of Prof. Dr. Lajos

Ronyai on January, 14th, I provided an overview of graph-traversal algorithms. The talk also

covered new compression data-structures that might prove useful for the data-mining project

carried out by Dr. Andras Benczur. In subsequent discussions we identified common research

interests, which we will pursue in the future. Making each other aware of recent results obtained

by third parties was also very helpful.



On February, 11th and 18th, I gave lectures at the TU Budapest on external-memory algorithms;

more details can be found under http://www.math.bme.hu/~ig/valfej/



(Válogatott fejezetek az algoritmusok körébõl) I was told that the students enjoyed the talks; an

external visitor from Ericsson Hungary attended the lectures as well. Giving these presentations

in front of an interested audience was a very good experience of my stay.



Parts of the research results obtained during my stay at SZTAKI will appear as a refereed full

paper at the 16th IEEE International Parallel and Distributed Processing Symposium to be held

this year in Fort Lauderdale, USA.



A preprint of this paper "Buckets strike back: Improved Parallel Shortest-Paths" is attached.

Valuable comments from SZTAKI members helped to improve both the presentation and the

analysis. This is also true for a revised journal version of my paper on sequential shortest-paths

from SODA 2001. My forthcoming invited talk at the Dagstuhl Seminar on Data Structures (

http://www.dagstuhl.de/DATA/Seminars/02/#02091 ) covering the papers above will directly

benefit from the visit at SZTAKI.



Altogether, I truly enjoyed my stay in Budapest; the warm spirit of the working group of Prof.

Ronyai allowed a fast integration. The general research conditions are fine; however, it would

be nice to have at least online access to some important publications series like "Lecture Notes

in Computer Science" (Springer) that are not regularly ordered by the library in printed form..

of Excellence MTA SZTAKI, Computer and Automation Research Institute of the Hungarian

Academy of Sciences, informatics Department and CIM Research Laboratory, headed by Acad.

Janos Demetrovics and Prof. George L. Kovacs.



During the last few years, SZTAKI and HRTC (Human Resources Training Center of

University “Politehnica” of Bucharest) have established a co-operation and knowledge

exchange. Currently, they joint consist into submission together with other partners, of a 5th

Framework Proposal Project, STAR, on stimulating the access to the Cultural Heritages.

Mr. Popa spent 2 months at MTA SZTAKI, from 15.01.2002 up to 15.03.2002.



GOAL OF THE REPORT

The goals of this report consist in:

Presenting the work done during the visit of Mr. Popa at MTA SZTAKI

Indicating the main results of the visit

Presenting the plans for future collaborations

Evaluating the visits achievements and summarising the main results.



OBJECTIVES OF THE VISIT

During his visit, Mr. Popa proposed himself to:

 Learn and understand the local solutions and to benefit the scientific progress of MTA

SZTAKI;

 Prepare new research proposals for submission to the EU into the 5th and the following

Framework Programmes;

 Work for the preparation of joint conference papers;

 Deliver scientific seminar series, technical presentations

 Work on his PhD thesis;

 Develop a suitable work environment for operating a virtual multimedia laboratory

connected with University “Politehnica” of Bucharest.



INTERACTION AT THE INSTITUTE

After the first contact with the realities and getting acquainted with the technical environment at

SZTAKI, Mr. Popa started to learn about the current research themes and topics in development

of the colleagues at SZTAKI, and with their precious help could understand the specific needs,

requirements and local solutions implemented.



In the first week, Mr. Popa sustained an Initial presentation of his expertise and research





20

themes. Principally, was described his interests areas and work results, the PhD Thesis focus,

and the common proposal project –STAR- for the EU 5th Framework Programme. This was the

basis for the future discussions on common research themes with experts of SZTAKI. At the

proposal of Dr. Otto Hutter, the Educational Service Manager at SZTAKI, Mr. Popa has

delivered a series of five Multimedia topics technical seminars, focused on Digital Media. This

has constituted another basis for co-operation on the running and future projects.

Attending to the numerous seminars and conferences, local or international –and here had to be

mentioned that these events are really useful by their high technical contents and valuable

information contained related to new fields of research and interdisciplinary co-operation- Mr.

Popa got an broad view of the subjects and the important results of the very best experts who are

working in the research environment at SZTAKI.



SCIENTIFIC WORK

Using written materials (reports, publication, etc.), Mr. Popa got acquainted with the technical

environment at SZTAKI and with the help of CIM Research Laboratory colleagues has used it

for his work. He learnt about the current research topics and the projects running at SZTAKI,

specifically on themes and projects addressed by the CIM research Laboratory, Educational

Service Center, Research Group on Intelligent Manufacturing and Business Processes,

A main task was to get involved with the formulation of the multimedia research environment,

developing a suitable work environment for operating a virtual multimedia-oriented research

laboratory connected with the University “Politehnica” of Bucharest. A real-life connection

was realised by working on the joint EU research proposal for EU 5th Framework: STAR

project proposal.

A great progress has been achieved in simulation and 3D modelling, virtual world environment

building in CIM systems. The results had been tested at the Technical University of Budapest,

Department of Manufacturing Engineering, experimental robotic and machining CIM cells. He

had been working with the new technology of 3D scanning of real-life objects for building

digital models in extended databases.

Another concrete result of collaboration was the delivering of two joint publication with

participation at two major International Conferences: “VIPRomCom-2002” -The International

Symposium on Video/Image Processing and Multimedia Communications, and “Gepeszet

2002”.

Beside scientific work, Mr. Popa was getting acquainted with the industrial solutions by

attending to discussions with experts from several Hungarian companies. By participating to an

important exhibition of the automation and control industry, has the opportunity to being

familiarised with the solutions and the strategies of big companies (PYRAMID, EYEVIS,

General Electric, etc.).



A special benefit was achieved by getting acquainted with the SZTAKI‟s current research

project DIMORF on digitisation of old movies, a special task of our joint project proposal,

VIMIMS – an ongoing ODL research project carried out by SZTAKI with other five European

research and educational institutes, and another EU project XPERTS- a project management

topic based on Rational Unified Process methodologies.

Sharing experiences with former and present Centre of Excellence visiting scientists –at Goethe

University Frankfurt where observed the on-site implementations of CNN chip and artificial

algorithms for study of Brain Activity for the realisation of an epilepsy warning and preventing

system, scientists from Artificial Intelligence Department of Academy of Sciences Sofia,

ERCIM guests from Holland and Austria, and others, helped in establishment of true

international collaboration in this scientific field.





21

FUTURE COLLABORATION

Continuous exchange on the research results will be established by regular exchange of

publications, and in the same time by preparation of joint publications. The competencies at the

CIM Laboratory at SZTAKI and MWPG at HRTC are to a large extent harmonious. This lead

to a natural joint contribution and collaboration on common subjects and other topics, involving

control, digital media, ODL, Virtual Reality. A virtual laboratory being established between

SZTAKI and HRTC provides complementarities in expertise of both sides. A very special

aspect of future collaboration consist in preparations for the common proposal in the 6th and

following EU Framework Programme.

Based on co-operation realised and results achieved, a joint supervision of PhD thesis became a

very interesting near future plan. In the perfect working conditions and with the precious help

of this excellently organized institute, a real “Centre of Excellence” any kind of occupation is

easy to get done with 101% success.

On the working table are also the development and improvement of the running projects, and a

tight co-operation in extending the knowledge network. These kinds of initiatives are very

useful for establishing tight collaborations among RTD organisations in Europe.



CONCLUDING REMARKS

The value achieved during this visit cannot be expressed in a short report. All the things are

valuable for future, and definitely ensure a tight collaboration among European scientists.

The visit was more then useful for Alexandru Popa, from all the points of view. Scientifical,

Technical, Social, Cultural. The experts friends from SZTAKI have openly presented their

results and enabled the visitor to fully get acquainted and to learn about the main results of the

Institute. The conditions provided by SZTAKI (working environment, organization,

accommodation, access to knowledge, technical infrastructure) were excellent.

This very fruitful and most enjoyable visit at SZTAKI was the result of contribution of the kind

people who make me even in this moment to feel and see on my working way, soul and mind

the sign of lessons learnt at Budapest. The support I received during my visit were exemplary,

and I am very grateful to Dr Geza Haidegger, Prof Dr. George Kovacs, Mrs. Elisabet Zudor

Angyalka, Prof.Dr. Lazlo Monostori, Dr. Otto Hutter, Dr. Sandor Kopacsi, Dr. Janos Nacsa, Dr.

Istavan Mezgar, Mr. Ferencz Sarkozy, Mr. Szilvester Drozdic, Dr. Kiraly Lazlo, Dr. Renner

Gabor and many others.

Very special thanks to Geza and Klara for your hospitality and the enormous time you spent on

me and all the pleasant activities that you arranged (I missing the great Budapest Opera

performances), Gyuri for the great trips outside Budapest, many thanks.

“Making virtual bridges of real friendships” is an appropriate name for this Centre of

PROLAMAT Conference Report –2001November, Budapest





The triennial PROLAMAT conferences focus on computer applications in manufacturing, and have

already a respectable history. The first conference in Rome, Italy in 1969 and the next in Budapest,

Hungary, addressed the issue of Programming Languages for Machine Tools, and created the acronym

PROLAMAT. While the acronym has not changed, the topic has shifted considerably. The conferences

have addressed Advances in CAM, Software for Discrete Manufacturing, Human Aspects of CIM and

Globalization and Virtual Enterprises; the aim of PROLAMAT 2001 is to demonstrate activities and

results that will characterize manufacturing in the 21st century. The conferences have covered a wide

geographical area, and have travelled around the globe. They left the European continent for Glasgow,

Scotland U.K. in 1976, then went on to Ann Arbor, Michigan, U.S.A. in 1979, followed by Leningrad,

U.S.S.R. in 1982, and after visiting some European cities it arrived at Tokyo, Japan in 1992. The last few

conferences came back to Europe.

The information technology revolution of the 1980s and 1990s made a strong impact on production

technology as well as on its management, and many of today‟s enterprises can rightly be called digital

enterprises. The pervasiveness of computers and networks has enabled the full computerization of

production, and further on the whole supply chain. Decision support systems and other management

support tools have also become more and more widespread.

As the web of computer networks gradually expanded, it opened up the possibility of global,

computer assisted production, management, etc. Different stages of the design and production process

can now be conducted at different parts of the globe, and still be overseen by real-time control and

management. Networked activities are not restricted to one enterprise: virtual enterprises allying

different companies for the lifetime of a project are heavily relying on computer-enabled

communication, cooperation and coordination, and business-to-business (B2B) commercial activities

via electronic communication are becoming everyday practice.

The computing power of today‟s equipment has reduced the calculation time of modeling and

simulation to such an extent that new approaches using computation intensive methods, techniques and

algorithms have become feasible to employ. Using modeling and simulation tools a wide range of

alternatives can be examined quickly to provide support for decisions. Design and manufacturing time

has also been reduced, which allows faster response to market needs.

The 2001 PROLAMAT focused on one of the greatest new challenges facing these digital

enterprises: Life Cycle Approach in Management and Production. In an increasingly environment

conscious world manufacturing and production is regarded as part of a larger picture: the product life

cycle (production – use – disposal). This approach is characterized by three aspects: technology,

economy and ecology (environmental impact). The PROLAMAT conference focused on technology but

also included papers on the other two aspects; various solutions for the different activities are





23

described in the papers. While elements of integrating several phases of the product life cycle have been

apparent in earlier approaches, such as Design for Manufacturing, Design for Maintenance etc., the life

cycle approach looks at the different phases from a holistic aspect.

Modeling can help in calculating the cost of a product, both in the manufacturing stage and in later

stages of the product‟s life. As cost can be a decisive factor in a product‟s success, support tools can be

used to facilitate the examination of economy aspects. Other uses of modeling include analysis and

simplification of complexities in the supply chain that includes life cycle dependencies. Using the

life-cycle approach a product model can be reverse engineered from the intended use and the given set of

constraints, and the optimum design is derived from the desired outcome.

The principal message of the conference was that engineering has to embrace the whole life-cycle of

the product, which includes environmental, social and economic sustainability of the production –

supply chain, customer use and disposition phases. Life cycle thinking integrates many different

processes to give a complete view; from product design to decommissioning and disposal.

Because of several reasons, including the terror attacks against the USA in September the

conference had only about 50 registered participants from 23 countries, including Brasil, Japan and the

USA – instead of the expected 100-150. This made the conference more friendly, a little workshop-like,

which was a positive thing allowing several professional discussions on joint projects, joint R&D

activities, etc.

The importance of the topic was evidenced by the large number of papers submitted to the

conference. Due to space limitations only some of them were selected for publication. The papers

included in the volume were considered by the program committee to provide the best insight into these

issues, and describe solutions for the problems. The selected papers of the conference were published by

Kluwer Academic Publishers in a very attractive hardbound book of 556 pages.There were a number of

people assisting in the editing process and organising the conference, and we wish to thank everyone

who contributed to the success of this conference for their efforts. We hope that this conference will lead

to further IFIP TC5 activities in the area, and which will also bring people from industry, research and

education closely together.

SZTAKI in PLANET: An Introduction





L. Monostori and J. Váncza



The Computer and Automation Research Institute of the Hungarian Academy of Sciences – SZTAKI in short –

performs basic and application-oriented research in the fields of computer science, intelligent systems, process

control, wide-area networking and multimedia. The Institute is active in graduate and post-graduate education,

cooperating with most of the technical universities in Hungary. The European Research Consortium of

Informatics and Mathematics (ERCIM) granted full membership to the Institute in 1994. SZTAKI is a PLANET

node since 2000.





In SZTAKI, members of the Laboratory of Engineering and Management Intelligence have been working for

more than a decade on planning, scheduling and production management problems of manufacturing. The

Laboratory has a long-standing interest in modular design, manufacturing process planning, distributed

scheduling, holonic manufacturing systems, agent-based control and the simulation of production systems, as well

as in the management of production networks. The Laboratory has regularly contributed to the Holonic

Manufacturing Systems (HMSs) project of the worldwide Intelligent Manufacturing Systems (IMS) initiative.





Our recent planning and scheduling related research topics are as follows:



Emergent production planning and scheduling We have an interest in the emergent control of manufacturing

systems that operate under uncertain and complex conditions [6]. We have developed a multi-agent model for

solving integrated order processing and dynamic production scheduling problems. The model is based on the

economic rationality of individual agents, though, by the application of a special incentive mechanism, reconciles

autonomous and cooperative behavior. Hence, the model paves the way toward so-called holonic manufacturing

systems [1,7]. Further on, we have developed an adaptable order selection and resource allocation model where

production balancing is made by reinforcement learning.





Constraint-based computer-aided manufacturing process planning Recently, we have modeled

computer-aided manufacturing process planning (CAPP) as a large-scale constrained optimization problem.The

model captures several kinds of resource, operation ordering and grouping (so-called setup) constraints. Two

planner systems have been built on the top of general-purpose constraint programming systems [2,8]. The planners

can cope with conditional and antagonistic (soft) constraints as well. The model is generic: it was validated in the

domains of machining prismatic parts and of bending sheet metals. Recently, customized search methods have

been developed that combine constraint satisfaction, branch-and-bound search and multi-dimensional Pareto

optimization. In the bending domain, planning was integrated with geometric reasoning.









33

Modelling industrial manufacturing systems: A method was developed to model complex production process

and process chains. The method that combines simulation and artificial neural network techniques was applied in

the optimization of process parameters [5]. We participate also in an international research consortium whose goal

is to establish a virtual institute focused on knowledge sharing and integration of competencies in modelling and

designing industrial manufacturing systems. This project applies on-line distance learning (ODL) techniques to

develop a portal applicable both for research and educational purposes.





The follow-up of these works is a currently launched mid-term national R&D project on digital factories. The

project, which is running with substantial industrial participation, focuses on resource-constrained project

management, production planning, tele-presence and interactive multimedia, as well as on the monitoring of

complex production processes.





SZTAKI helped to organize international conferences on the application of AI in manufacturing and engineering -

such as the 2nd World Congress on Intelligent Manufacturing Processes and Systems [3] and IEA/AIE-2001, the

14th International Conference on Industrial & Engineering Applications of Artificial Intelligence & Expert

Systems [4].

IMS NOE



SZTAKI took part in the successful Network of Excellence proposal on Intelligent Manufacturing Systems (IMS

NOE). Moreover, SZTAKI is the leader of the subgroup on Manufacturing Scheduling and Control in the

Extended Enterprise.



The main medium-term goals of the NOE are: to strengthen the European involvement in the world-wide IMS

community; provide a stimulating and high-quality forum for discussion, exchange of ideas, planning for

collaboration and debates about trends, research and further developments of IMS concepts; provide a Web-based

Benchmarking Service for the research and industrial community; provide a Technology Observatory to elaborate

and update at regular intervals Technology Roadmaps and Expertise Maps within the Network's scope at European

level; to anticipate the EU's scientific and technological needs in order to help the EU to react rapidly to new

scientific and technological developments.



VIMIMS



SZTAKI took part in the SOCRATES-MINERVA Program of the European Union with the successful proposal:

VIVIMS: Virtual Institute for the Modelling of Industrial Manufacturing Systems.



The main objective of the project is to establish a Virtual Institute specifically focused on knowledge sharing and

integration of competencies in the educational and research area of Modelling and Design of Industrial

Manufacturing Systems (MIMS). The adoption of ICT tools will be functional to a first reorganisation of the

current learning process, by integrating conventional modes with the most innovative approaches based on ODL.

At the end of January, a 2 day VIMINS working conference was organised at SZTAKI.



E-Factory DNA



SZTAKI - as the member of the Scientific Committee in the E-Factory DNA EUREKA Cluster Project on

Products, Processes, Enterprises for competitiveness and sustainability of European Manufacturing Industry

towards globalisation and new economy.



ERCIM WORKING GROUP ON CONSTRAINTS



SZTAKI joined, as a full member of the European Research Consortium for Informatics and Mathematics

(ERCIM), the so-named ERCIM Working Group on Constraints.

Constraints have recently emerged as a research area that combines researchers from a number of fields,

including Artificial Intelligence, Programming Languages, Symbolic Computing and Computational Logic.

Current research in this area deals with various foundational issues, with implementation aspects and with new

applications of constraint programming. Our main concern is in this area in the application of the constraint

technology to large-scale combinatorial optimization problems with industrial background such as process

planning, production planning, scheduling.

The WG brings ERCIM researchers together , involved in research on the subject of Constraints. Its aims

are to promote research on this subject within the ERCIM institutions, facilitate the exchange of information,

co-ordinate efforts in technology transfer, and facilitate the exchange of researchers for short and long visits. The

ERCIM WG on Constraints has at the moment 15 member institutes.

Group Decision Support Systems



Laboratory of Operations Research and Decision Systems Head: Tamas Rapcsak



With the significant assistance of the members of the Laboratory, the Hungarian Operations

Research Society (HORS) continues organizing the dissemination of newest developments in

operations research. At the annual conference in 2001 (October 17-20, Debrecen) the members

of the Lab gave several talks.



The Head, Prof. Rapcsák coedited the a special issue for European Journal of Operations

research (EJOR) containing the papers delivered at EURO 2000, the world congress in

operations research. The issue is in print now.

The volume of lectures on operations research delivered at Assembly Meeting 2000,

Millennium at the Academy, were coedited by Prof. Rapcsák came out of print just now.

Another conference proceedings collecting the selected papers read at International Conference

on Numerical Methods and Computational Mechanics in 1998, Miskolc was coedited by Prof.

Balla and published as a special issue of Intern.J.Computers and Math. with Appl.



The weekly seminars at the Laboratory became a meeting point for researchers from the

universities of Budapest and the countryside. Prof. J.Sun of National University of Singapore

and Prof. P. Lancaster of University of Calgary, Canada visiting here for a short period gave

talks titled Semismooth Matrix-Valued Equations and Recent Results in Perturbation Theory

for Analytic Matrix Functions, respectively.





Holder of the Humboldt Scholarship Dr. Mészáros gave a talk aiming at acquainting the

colleagues with the aims and scopes of the scholarship. Results of his visit at FU Berlin and the

work on development the interior point algorithms and their implementation made in

cooperation with researchers at FU Berlin were delivered.



Research on equilibrium systems, variational inequalities and related topics as well as on

differential algebraic equations is going on in international cooperation with professors of

University of Pisa and HU Berlin, Computer Centre of Russian Academy of Sci. Recent

results are in print in acknowledged journals.



Participation (by Dr. J. Fülöp and M. Prill) in SIADCERO project (Strategic Integrated

Assessment of Dynamic Carbon Emission Reduction Policies) of European Union resulted in

development of modelling tools and computational algorithms for analysis of the strategic

interests and policy options of the EU in international negotiations on climate change. Game

theory approach and the Excel add-in for the computation enabled evaluation of several

versions.



A postdoc from Zagreb University, Croatia, V. Horvat visiting the Laboratory for almost a year

learnt here the DAE and DE theory. He ended up his stay here with a paper written jointly with

a member of the Lab (Balla). The paper is in print now.
