The 9th WSEAS Circuits, Systems, Communications and Computers Multiconference,
known as CSCC was held in
(Hotel ARMONIA), Athens, Greece from July 11 till July 16, 2005.
More than 1000 papers were submitted to the multiconference and from them 450 papers were accepted.
The authors of the best of the accepted papers received an invitation for sending an extended version
to the WSEAS reputable International Journals. The Multiconference was composed by the following conferences:
9th WSEAS Int.Conf. on CIRCUITS (July 11-13, 2005)
9th WSEAS Int.Conf. on SYSTEMS (July 11-13, 2005)
9th WSEAS Int.Conf. on COMMUNICATIONS (July 14-16, 2005)
9th WSEAS Int.Conf. on COMPUTERS (July 14-16, 2005)
The Multiconference offered 2 Banquets with live greek and international orchester, singers, and a great ballet of 8 dancers. The first banquet took place in July 12 and the second banquet in July 15. More Details below. 4 student prizes were awarded for the best student papers by the Organizing Committee.
More Details below.

Accepted papers:
from these 450 papers, the WSEAS Committee approved additional Journal Publication for the best papers of the multiconference.

Review Process: Each paper was reviewed at least by 3 independent reviewers. The WSEAS Secretariat sent each paper to 5 reviewers. Some papers received review from 5 different referees. The WSEAS Secretariat had forwarded to the responsible for the correspondence author these comments by personalized emails. The full list of the reviewers will be available in the web page:

Only authors of those papers, which are found to have very positive response from 3 referees and which are modified satisfactorily to take into account all the comments of (at least 3)  referees of the conference are invited to send an extended version in the WSEAS Journals (WSEAS Transactions). The extended version is checked again by two additional referees and a rejection or acceptance is notified to the authors. WSEAS Organizing Committee therefore congratulates those, who have been able to get the distinction of having their paper published in the Transactions.

WSEAS sent a full report of the whole review process and the whole correspondence
to the following international indexes that have recognized officially the Validity and the Reputation
of the WSEAS Conferences:

* AMS (American Mathematical Soceity),
* Mathematical Reviews,
* CSA,
* ELP,

The Impulse-Response Scandal And The Foundations Of Linear System Theory

Professor Irwin W. Sandberg,

In the photo in the left: Prof. Irwin Sandberg was presenting his Keynote Speech (July 11, 2005)

Abstract: It is a widely-held belief that the main textbook conclusions concerning continuous time linear systems obtained using Dirac delta-function arguments can be shown to be valid using the mathematical theory of distributions. But this belief is unwarranted. For example, in a recent study of multidimensional input-output maps representing linear shift-invariant systems that take a set of continuous-space signals into itself, it was shown that the family contains maps whose impulse response is the zero function, but which take certain inputs into nonzero outputs. In this connection, we give an expression for the most general input-output map associated with the members of a certain important large family of multidimensional linear systems. This expression is a uniform limit of a convolution. We also give a necessary and sufficient condition under which the limit can be written as a convolution, and we relate this to the concepts of an impulse response and a q-response limit, and to the flawed concept of the Dirac function. The talk will be addressed to a general circuits and systems audience, and will include a pertinent historical survey as well as material concerning engineering education.

Abstract: Nowadays, scientists, engineers and businessmen working in diverse fields have one problem in common: they all have to deal with large datasets which arise in a broad spectrum of areas, including finance, banking, manufacturing, supply chain, medicine and biotechnology, telecommunications, military systems, etc. In many cases, in order to discover useful information from a certain dataset, mathematical programming approaches are successfully applied. We discuss one of the promising research directions in data mining - using network-based models for data analysis and decision making. In many practical situations, a real-world dataset can be represented as a large graph (network) with certain attributes associated with its vertices and edges. These attributes may contain specific information characterizing the given application, which often provides a new insight into the internal structure and patterns of the data. The considered examples include telecommunications, biomedicine, and finance.

Arrayed Wireless Sensor Networks and MIMO Systems

Professor Athanasios Manikas
Deputy Head of Communications & Signal Processing Research,
Department of Electrical & Electronic Engineering, Imperial College London,

Prof. Athanasios Manikas was presenting his Plenary Lecture (June 14, 2005)

Abstract: In this Lecture the application of array processing techniques and array communications for enhancing the operation of a wireless sensor network will be presented and the concepts of 'wireless arrays' and 'arrayed wireless sensor networks' (A-WSN) will be introduced. A-WSN is a novel type of wireless sensor networks involving a very large number (hundreds or thousands) of wireless nodes that are randomly distributed in our 3-dimensional (3D) space in unknown locations and are used for monitoring events of interest. When such events occur, nodes will automatically communicate and self organize with their immediate neighbours to form wireless array systems of suitable, although random, geometries and then an ad-hoc wireless network of arrays operating in an infrastructure-less environment. A number of underlying issues under a common framework will be presented such as, node architecture, connectivity rules, communication link requirements (e.g. limited bandwidth, modulation, etc), resolution capabilities (resolving information sources located close together), channel and geometrical uncertainties, etc. These issues will be underpinned by exploiting the knowledge associated with MIMO (multiple-input multiple-output) and MIVO (matrix-input vector-output) wireless architectures in mobile array systems, to wireless sensor network requirements.

New Trends in Control Theory: From ADP to MPC

Professor Dimitri P. Bertsekas,

Two important directions of research and application in control theory have emerged recently, both of them centered around Dynamic Programming. These are Approximate Dynamic Programming (ADP) and Model Predictive Control (MPC). We argue that while motivated by different concerns, these two methodologies are closely connected, and the mathematical essence of their desirable properties is couched in common ideas of value and policy iteration. In this talk, we explore the connections of several suboptimal control schemes such as certainty equivalent control, open-loop feedback control, rollout, and MPC. Among other things, we show that the most common MPC schemes can be viewed as rollout algorithms or one-step policy iteration methods. Furthermore, we introduce a new unifying suboptimal control framework, based on a concept of restricted or constrained polices, that contains these schemes as special cases.

Due to the great duration of the 9th WSEAS CSCC (6 days) the Organizing Committee offered 2 Banquets to attendees. One in July 12 and another in July 15. In each banquet each participant enjoyed greek and international cuisine from over than 45 different dishes (self-service menu), over than 5 different sweets and over than 5 season fruits, as well as red and white wine, beer, greek ouzo (per request) and coffee.
the Organizing Committee offered 12 very good coffee-breaks.
The rich coffee-breaks were composed by filter coffee, tea, 4 juices, cakes, biscuits, sweets and fruit tarts.
Each Banquet took place around the swimming pool of the Hotel "ARMONIA".

The Second Banquet had two pleasant surprizes:
We celebrated the 41 birthdate of our WSEAS President, Professor Mastorakis as well the 50th marriage anniversary of Prof. Ray Hefferlin.

"Bouzouki" is  the national musical instrument of Greece. The musical group of Mr. Nikolouzos gave a special greek summer night to the WSEAS guests. (Second banquet, July 15, 2005)

More than 150 WSEAS participants participated in our dance of July 15.  (Second banquet, July 15, 2005)
