POWER ELECTRONICS AND INTELLIGENT CONTROL FOR ENERGY CONSERVATION - CENTRE OF EXCELLENCE

2007 PELINCEC Newsletter http://pelincec.isep.pw.edu.pl No. 12

The first international conference which was held by the

Institute of Control and Industrial Electronics in year 2007

was the International Conference on Natural and Adaptive

Computing Algorithms – ICANNGA’07.

The ICANNGA series of Conferences is organized since

1993 and has a long history of promoting the principles and

understanding of computational intelligence paradigms

within the scientific community. Starting in Innsbruck, in

Austria (1993), thence to Alès in France (1995), Norwich in

England (1997), Portoroz in Slovenia (1999), Prague in

Czech Republic (2001), Roanne, in France (2003) and

finally Coimbra in Portugal (2005), the ICANNGA series has

established itself as a reference for scientists and

practitioners in this area. The series has also been of value

to young researchers wishing both to extend their knowledge

and experience and also meet experienced professionals in

their fields.

In a rapidly advancing world, where technology and

engineering change dramatically, new challenges in

computer science compel us to broaden the conference

scope in order to take into account new developments.

Nevertheless we have kept the acronym ICANNGA which,

since the Coimbra conference in 2005, stands for

International Conference on Adaptive and Natural

Computing Algorithms.

The 2007 Conference, the eighth in the ICANNGA series,

took place in Warsaw in April, 11-14, drawing on the

experience of previous events, and following the same

general model, combining technical sessions, including

plenary lectures by renowned scientists, with tutorials and

workshop panels.

Warsaw edition of ICANNGA attracted many scientists from

all over the world. We had received 474 mostly high quality

submissions from 40 countries. After rigorous review

involving more than 160 experts in their fields, 178 papers

were accepted and included in the proceedings. The

acceptance rate was only 38% enforcing high standard of

papers.

The conference proceedings are published in two volumes

Springer’s Lecture Notes in Computer Science: 4431 and

4432. The first volume (LNCS 4431) of the proceedings is

primarily concerned with issues related to various concepts

and methods of optimization, evolutionary computations,

genetic algorithms, particle swarm optimization, fuzzy and

rough systems. Additionally there is also a set of papers

We would like to thank the International Advisory Committee

for their guidance, advice and discussions. Our special

gratitude is devoted to the Programme Committee and

reviewers. They have done a wonderful job of shaping the

conference image. Numbers of our Electrical Engineering

Faculty, the Control Division Staff members and the Ph.D.

students were involved in various conference tasks,

preparing the conference proceedings supporting the

conference secretariat and maintaining multimedia

equipments. We are greatly appreciating all they have done.

Finally, the conference is made of papers and presentations

prepared by our contributors and participants. Most of the

gratitude is directed to them.

Following its tradition of travelling across Europe, the next

event of the series, the ICANNGA'09 will be organized in

Kuopio, Finland in 23-25 April 2009. For more detailed

devoted to clustering and classification. The second volume

(LNCS 4432) is mainly concerned with neural networks

theory and applications, support vector machines,

biomedical and biometrics applications, computer vision,

control and robotics.

ICANNGA’07 was enjoyed plenary lectures presented by

distinguished scientists: Shun-ichi Amari from Japan,

Ryszard Tadeusiewicz and Janusz Kacprzyk from Poland,

Kevin Warwick and Rafal Zbikowski from England.

The conference was accompanied by social events. The first

of them was the organ and choral music concert organized

under auspiced of Dean of the Electrical Engineering Faculty

in the St.Saviour’s Church located within 5 minutes of walk

from the main campus of WUT. The concert was performed

by Mr. Piotr Rachon – organ and the Song and Dance

Ensemble of Warsaw University of Technology. Just after the

concert, we invited the ICANNGA participants to the

Welcome Reception in the Building of Phisics located in the

heart of the Central Campus of WUT, one of the oldest

edifices of our University. Next day afternoon, the

conference participants took part in the Gala Dinner, which

was held in the Jabłonna Palace. This beautiful palace is a

part of an 18th century elegant palace-and-park complex

situated on the outskirts of Warsaw, about 20 km. from the

ICANNGA’07 participants before the Gala Dinner in Jablonna Place near Warsaw

The 2007 IEEE “International Con-ference on Computer as a

Tool” EUROCON was successfully held on September 9-12,

2007 in Warsaw, Poland. EUROCON is the largest IEEE

conference in Europe and belongs to the flag IEEE Region 8

conferences, together with AFRICON, MELECON, and,

recently SIBIRCON as well as HISTELCON. Recent

EUROCONs were held in Bratislava, Slovakia in 2001,

Ljubljana, Slovenia in 2003, and Belgrade, Serbia and

Montenegro in 2005. The topics covered by 2007 IEEE

EUROCON included system design, signal and image

processing, measurements and sensors, computation

intelligence and control, telecommunications and multimedia,

photonics, power systems and power electronics, electrical

machines and drives, electron device, modeling and

simulations, and education. Over 670 abstracts were

submitted in response to 2007 EUROCON call for papers,

out of which 477 from 53 countries have been selected as

conference publications. Approximately two-third of them

was presented in 34 Oral Sessions and the remaining was

included into three Poster Sessions. There were also 9

Special Sessions presented by highly respected specialists

from science and industry. Most of participants came from

Region 8 (Europe, Middle East and Africa); however, there

Energy saving and improved energy efficiency is a major issue for drives and generator systems development. Power electro-

nics technology is the key for energy efficient variable speed drives. Applications range from the low power area e.g. in home

appliance over medium power in industrial and automotive up to the large MW power in the field of generation. There is still

progress in electrical machines motors and generators that are going to be more efficient, lighter and more robust. The main

types of variable speed drives have been industrial drives where the competition between many players has been strong and

pushed the technology to have a high power density with high performance At still lower costs. New variable/adjustable Speer

generation technologies are key issue for improvement of electricity generation industry. An emerging SiC technology, applied

to power electronic devices, brings another revolutionary change in system performance and efficiency. The ECPE Seminar is

presenting research and technology trends including emerging Technologies and new applications. The goal of the seminar is

to offer high level education and information exchange. Prof. W. Koczara (Warsaw University of Technology) will chair the

seminar together with Michel Arpilliere (Schneider Toshiba Inverter Europe) and Thomas Harder (ECPE). All presentations

and discussions will be in English.
