Concurrent Self-Organizing Maps – A Powerful Artificial
Neural Tool for Pattern Recognition

Professor Victor-Emil Neagoe

Department of Electronics, Telecommunications and Information Technology

Polytechnic University of Bucharest

Splaiul Independentei 313, Bucharest, Romania

Abstract: The Self-Organizing Map (SOM) (also called Kohonen network) is an artificial unsupervised network characterized by the fact that its neighbouring neurons develop adaptively into specific detectors of different vector patterns. The neurons become specifically tuned to various classes of patterns through a competitive, unsupervised or self-organizing learning. Starting from the idea to consider the SOM as a cell characterizing a specific class only, Neagoe proposed and evaluated in [1], [2] a new neural recognition model called Concurrent Self-Organizing Maps (CSOM), representing a collection of small SOMs, which use a global winner-takes-all strategy. Each SOM is used to correctly classify the patterns of one class only and the number of networks equals the number of classes. The CSOM is a system of systems. The model proved to have better performances than SOM, both for the recognition rate and also for reduction of the training time.

Collaboration – A Business Strategy in the Global Economy

Professor Mihaela Muntean

Head of the Business Information Systems Department

Faculty of Economic Sciences

West University of Timisoara

Romania

mihaela.muntean@fse.uvt.ro

Abstract: Collaboration involves a different approach to business – focused on managing business relationships between people, within or without groups, and within and between organizations. Collaborative enterprises differ from other business in a number of ways and collaborative working needs to be simultaneously a business philosophy, strategy and operational working. Effective collaboration unlocks the potential of the collective knowledge and intellectual capital of the organization and its networks of business partners, suppliers and customers. At the core of true collaboration is the ability to share and catalog knowledge, ideas, standards, best practices, and lessons learned and to be able to retrieve that knowledge from anywhere at any time. Business decisions are only as good as the information on which they are based. Integrating all kind of collaboration capabilities into an enterprise portal together with business intelligence tools, we can build a powerful IT infrastructure for the collaborative enterprise.

Abstract:

(1) The need of a geographical model beyond the point model:

To emerge from the World Dynamics model created by D. H. Meadows and his colleague, I would like to examine the causes and the effects occurring and interacting in individual regions then foresee the future world as a sum of those regional activities

(2) Tessellation of the Earth surface:

      The precede example is a global climatic model using a 10 x 10 Km mesh in size today thanks to advanced supercomputers. As a very first step forward, I tessellate the Earth surface by 9 along the latitude, and 10 along the longitude.

(3)  Estimation of food supply and demand around 2030 (presenting at EED'06):

     Based on the UN population census and the FAO food census, I calculate the food

     supply and demand by regional bases and obtain an interest regional unevenness.

(4)  Simulation using 4 parameters on regional basis:

     I am calculating the worldwide interaction of energy, environmental stresses, and food supply to present at EED'07.

Fractional Tumor Development

Dr. Alexander Iomin

Department of Physics

Technion - Israel Institute of Technology

iomin@physics.technion.ac.il

Abstract: A simple mathematical model is proposed to study the influence of cell fission on transport. The model describes fractional tumor development, which is a one dimensional continuous time random walk (CTRW). A chemotherapy influence on the CTRW is studied. We find a condition when chemotherapy compensates cell proliferation and leads to either a fractional transport with a conservation of a number of cells or a stationary solution which describes time independent localization of cancer development. A specific feature of the analysis is cell diffusion in a periodic potential. This can model, e.g., metastasis cell transport along spinal column, where vertebrae make a periodic potential.

Air Quality CFD and Mesoscale Modelling Simulations: Madrid Case Study

Professor Roberto San Jose

Director / Environmental Software and Modelling Group

Computer Science School - Technical University of Madrid

Campus de Montegancedo - Boadilla del Monte-28660

roberto@fi.upm.es

Abstract: In this contribution we show the implementation of an adapted CFD code, developed by the University of Karlsruhe (Germany) and a mesoscale air quality modelling system composed by MM5 (PSU/NCAR) and CMAQ (EPA, US) and an emission model EMIMO, developed by the Technical University of Madrid (UPM). The system included a cellular automata model, CAMO, developed by UPM as part of the traffic emission system in order to accommodate the high spatial and temporal resolution emission datasets which are required by the CFD model. The CFD and emission system is called MICROSYS. The mesoscale meteorological and air quality dispersion model provides the boundary and initial conditions for MICROSYS. Different scenarios have been tested based on the reduction of traffic cars and increase of public transportation. The results show that the MICROSYS and the mesoscale air quality modelling system provide detailed and sensitive results to the different scenarios. The results show that the system can be used for analyzing many different situations in urban environment with a high level of detail and could be used as a management tool for air quality impact studies at urban level.

A Stochastic Solution Methodology for Inductance Extraction in
IC Interconnect Structures

Abstract: With operating frequencies reaching the multi-GHz range, the role of on-chip inductance is becoming increasingly important. The role of inductance in the interconnect model is particularly significant in clock distribution networks and in signal and power lines, which have wide wires and hence low resistance. The detrimental effects of inductive impedance on system performance include increase in signal delay times and signal overshoot which can cause breakdown of the gate-oxide layer. As a result, accurate modeling and extraction of inductance have become necessary.

Over the past few years, we have been working on the development of a stochastic solution methodology for the extraction of inductance in interconnect structures. Stochastic solution methods do not require the discretization of either the volume or the surface of problem domains. As a result memory requirements are low compared to discretization-based deterministic methods such as the finite difference, the finite element or the method of moments. Another advantage of stochastic solution methods is that an almost linear rate of parallelization is obtained for a very large number of processors. In this lecture, I will talk about some very exciting results that we have obtained and future research directions.

Wireless Mobile Communication Systems without Pilot Signals

Professor Motti Haridim

Department of Communication Engineering

HIT-Holon Institute of Technology, Israel

mharidim@hit.ac.il

Abstract: We propose an innovative method of multiple access, known as Frequency Bank Signal (FBS). FBS combines the phase shift compensation method used in the PAL-TV system, the OFDMA principle and the spread spectrum concept with Walsh functions.

The main advantage of using FBS is that the error probability is almost non-sensitive to the Doppler Effect, separate signals delay and to the influence of fading. In addition, FBS does not require any special pilot, synchronization or equalization signals.  Our simulation results show that the FBS has superior performance over OFDM under similar conditions. The proposed method can be implemented in all modern wireless communication systems.

Abstract: RoF(Radio on Fiber) is a promising technology for mobile communication systems. By using the RoF technology, wireless signal is transmitted through the optical fiber directly. Transceivers can be equipped in the switching station side and base stations are composed of only O/E transducer, amplifier and antenna. Thus the RoF technology reduces the size of base station remarkably. This compact base station is very important for future mobile communication systems because a huge number of micro-cell base station must be equipped to provide higher capacity and higher bit rate services. The presentation introduces recent RoF technology for indoor cellular systems. New research for RoF technology is also presented. Base station electrical power is supplied through the fiber by sending strong optical power. The feature is that the base station becomes more compact and easier to install everywhere by eliminating the power supply.

Fluid-Structure-Interaction: Fundamentals and Engineering Applications

Prof. Dr.-Ing. F.-K. Benra

University of Duisburg-Essen

Faculty of Engineering Sciences

Institute of Energy and Environmental Engineering

Chair for Turbomachinery

friedrich.benra@uni-due.de

Abstract: Many processes in nature and technology can be described only by using laws and equations from different physical disciplines. Such examples, for which the arising sub-problems cannot be solved independently, are called multi-physics applications. A very important class of these multi-physics problems are the fluid-structureinteractions (FSI), which are characterized by the fact, that the flow around a body has a strong impact on the structure and/or on the movement of the body and the modification of the structure or the position of the body or a component of the body due to the flow has an influence on the flow which is not negligible. The two disciplines which are involved in this kind of multi-physics problems are the fluid dynamics and the structure dynamics which both can be described by the relations of continuum mechanics. Examples of FSI exist in many fields of the natural sciences and the technology. Solutions for the mathematical description of fluid structure interactions can be obtained only by numerical simulations, which still today are a big challenge of scientific computation. In this contribution initially the fundamental relations for the calculation of the flow behavior and of the structure dynamics will be presented and approaches for numerical solutions of coupled FSI-systems will be pointed out. Afterwards different kinds of coupling methods for the two disciplines and possible methods of partitioning of the numerical simulations are described in detail and evaluated regarding the dependence of the two disciplines from each other. A detailed discussion of solutions for several FSI-examples brings the contribution to conclusion.

The principle of Turbulent Frame Indifference in Large Eddy Simulation

Professor Francesco Gallerano

Dipartimento di Idraulica

Facolta di Ingegneria

Universita di Roma "La Sapienza"

ITALY

francesco.gallerano@uniroma1.it

Abstract: In the framework of ordinary continuum thermodynamics turbulence models could be interpreted as constitutive equations which are necessary to close the equations of motion and the internal energy equation. The principle of Turbulent Frame Indifference is the equivalent in turbulence of the principle of Material Frame Indifference and implies form-invariance and frame indifference on the turbulent closure relations (Hutter & Joenk, 2004). Sadiki and Hutter (1996) emphasized that form-invariance and frame-independence are two distinct matters. A turbulent closure relation is form-invariant if it does not modify its formal expression under transformations of the frame and is constructed only with objective tensors. A turbulent closure relation is frame indifferent if it is expressed in terms of tensors that are independent of the angular and translational velocity of the frame. Weiss and Hutter (2003) emphasized the difference between the form-invariance and the frame indifference by underlining the existence of tensors that are objective but dependent on the angular velocity of the frame. A turbulent closure relation, which is expressed in terms of objective tensors that are dependent on the angular velocity of the frame, does not fulfil the principle of Turbulent Frame Indifference, because it is form invariant but frame dependent. Must all the turbulent closure relations fulfil the Principle of Turbulent Frame Indifference? The turbulent phenomena are not associated to the properties of the materials: consequently, turbulent closure relations do not represent the material behaviour. Turbulent closure relations must always be form invariant, but must not necessarily be frame indifferent (Hutter & Joenk, 2004). In other words not all the turbulent closure relations must fulfil the principle of Turbulent Frame Indifference. In the turbulent closure relations, the modelled expressions of an unknown objective tensor must be formulated in terms of objective tensors (allowing the closure relations to fulfil the requirement of form invariance) and must retain the same dependence (on the angular velocity of the frame) of the unknown tensor. As demonstrated by Gallerano et al. (2005), the generalised SGS turbulent stress tensor in LES is an objective tensor and is independent of the angular and translational velocity of the frame. Consequently, the closure relation for this tensor must fulfil the principle of Turbulent Frame Indifference. A new closure relation for the generalized SGS turbulent stress tensor is presented. In the proposed model the generalized SGS turbulent stress tensor is related to the generalized SGS turbulent kinetic energy and its viscous dissipation. It is demonstrated that the balance equation of the viscous dissipation is form-invariant but frame-dependent under Euclidean transformations of the frame; the proposed closure relations allow the modeled balance equation of the viscous dissipation to respect the properties of form-invariance and frame-dependence of the exact equation.

Geometric Moire and its Applicability for Dynamical Systems

Professor Minvydas Ragulskis

Department of Mathematical Research in Systems

minvydas.ragulskis@ktu.lt

Abstract: Geometric moire is classical full-field non-destructive optical experimental technique applied for measurement of in-plane fields of deformation and strain. It is based on subtractive superposition of moire gratings which are usually comprised from arrays of parallel lines. Patterns of moire fringes are produced when image of the grating in the state of equilibrium is superposed with another image of the deformed grating.

What would happen if moire grating would oscillate and time averaging techniques would be used to form the image of the oscillating system? Would any time averaged fringes form at all? And if they would form how could they be interpreted? The presented study of applicability of geometric moire for dynamical systems answers to these basic questions. It is shown that time average geometric moire can be effectively applied for analysis of meso-, micro- and even nano-scale dynamical systems. Moreover, these techniques are developed for analysis of chaotic oscillations and generalised for stochastic systems and super moire applications.
