Abstract: This presentation focusses a selection of nanotechnological topics in photonics on the field of research and application. In nanotechnology geometric variations of surface or interface structures enables to modify the physical material properties considerably and to tailor new “artificial” properties. First, these basic principles will be highlighted in photonics on (i) metallic nano-clusters of different size and on (ii) quantum structures for advanced laser devices. The presentation of these basic principles will be continued by photonic crystals of different dimensionality (1D, 2D, 3D), which often play a major role in this context. This is highlighted in the presentation including also examples from biology or nature. This leads to the interesting field of bionics, relating biology and technical areas. Bionics transfers the principles of success of nature into natural science, engineering disciplines and applications. Often generation and detection of different spectral colors play key roles in communication in both, nature and technology. The latter one refers e.g. to dense wavelength division multiplex optical communication systems. This paper shows interesting parallels in tunable spectral light filtering by butterfly wings and by tunable optical filters used in optical communication systems. In both cases light interferes constructively and destructively with nano- and microstructures of appropriate shape, dimensions and materials. In this paper methodology is strongly emphasized. Another very important topic of this talk will be tailored scaling, which tries answer the question of optimum size of systems. We demonstrate that tailored scaling allows the effectiveness of physical effects to be enhanced in nature and technology. Finally the potential of tailored scaling in micromachining to improve the photonic device properties, to enhance stability and yield is presented. As an example for the transfer of the principles of success of nature into technological applications we will look more detailed into micromachined spectrally tunable optical filters and lasers for information technology, sensorics and analytics are presented. These structures show amazing parallels to nature. Finally high reflective Bragg-Mirrors are fabricated for extreme ultraviolet lithography (EUVL) are presented. These structures are very important for the next generation integrated circuit chip production.

Best approximation of function classes on the real line and spline interpolation


Professor Gennadi Vainikko

Institute of Applied Mathematics

Tartu University

J. Liivi 2, 50409 Tartu



Abstract: Given the values of function f on a uniform grid of a step size h on the real line, we construct the spline interpolant of order m, defect 1 using the B-spline basis obtained by wavelet-type dilation and shifts from the father B-spline (which can be treated as a scaling function for a special nonorthogonal wavelet system). We establish an unimprovable error estimate of the interpolants for the class of functions with bounded mth derivative. We show that in the sense of worst case, all other approximations to f using the same information about f are more coarse than the spline interpolant. Some further error estimates are established, in particular, error estimates for a quasi-interpolant to  a function given on a bounded interval. 






Quasi Being of Neurons and Fuzzy Logic of Brain


Professor Lev Tsitolovsky

Department of Life Science

University of Bar-Ilan

Ramat-Gan  52900, Israel



Abstract: Brain is the same complex, puzzle and attractive object in the universe. It generates goals, does not need in the external programming and has many unique properties. Elemental learning, memory and goal-directed behavior are not an emergent property arising from a whole brain, but are the attribute of a neural cell, as a unit. In special circumstances, a single neuron may play a key role in the behavior of an entire animal. After learning, a neuron evaluates the significance of the signal, transiently changes their own excitability and only later compares the magnitude of this signal and threshold. The primary feature of the brain is capability to perceive and to produce an agency. We suggest that excitation and inhibition are perceived by a neuron as negative and positive states. Intentional actions may be a consequence of the endogenous compensation of a drop in excitability after damage induced by a motivational excitation. Homeostasis regulates the number of physiological parameters, but it can support any factor at the value that differs on the predetermined standard due to the compensatory changes of other parameters. So, we believe that fuzzy sets and fuzzy logic approach is sufficient not only for adequate description of a neuronal behavior, but for actual mechanism of a neuron's self-controlling as well. We consider exertion in neuronal metabolism as a driving force, which induces actions directed against actual or anticipated damage. Resulting goal-directed behavior is rather appropriate for description of aware decision-making and fuzzy logic.  






Control of Dynamical Systems in Models for Cancer Treatments


Professor Urszula Ledzewicz

Department of Mathematics and Statistics

Southern Illinois University

 Edwardsville, USA



Abstract: In this talk I will discuss the analysis of dynamical systems arising in biomedicine that describe various treatments of cancer. Mathematical models for cancer treatments have a long history, but with the development of medicine new challenges in modeling and the analysis of these models are appearing. Here cancer dynamics and treatment approaches will be discussed in the framework of optimal control theory. A general overview with examples of cell-cycle specific models will be given, some including multiple drug therapies, and challenges in modeling cancer treatments will be addressed. One of them, the important obstacle of evolving drug resistance in cancer chemotherapy, will be covered in more detail and its effect on the modeling of dynamics will be discussed. As an answer to this problem a new development in cancer treatment, anti-angiogenesis, will be presented. The importance of this novel treatment is that by targeting the cells of the vascularization of the tumor rather then the tumor itself, these methods are “resistant to drug resistance”. In the talk a mathematical model for cancer treatments with angiogenic inhibitors will be analyzed and a full synthesis of optimal controls will be constructed.

Electricity, the human brain and information technologies

From the voltaic pile to neural networks


Professor Francesco Muzi

Department of Electrical Engineering and Computer Science

University of L’Aquila, Italy



Abstract: The latter half of the 18th century, Galvani’s famous experiment and Volta’s subsequent insight, marked the beginning of two branches of science that were to change the human life radically. Later on, the two new branches, namely electrology in physics and electrophysiology in medicine, although started together, followed different paths. On the one hand electrical engineering, electronics, and information technologies developed whereas on the other hand evolved electrophysiology, electrical and electronic diagnostics, and digital medical engineering. As a matter of fact, in the past but also in recent years there have been remarkable advancements in electrophysiology. The changes in the electric potential due to biological activity are acquired outside the body and can identify any normal or abnormal behavior of organs such as the heart (electrocardiogram), the muscles (electromiogram), the brain (electroencephalogram), the eyes (electroretinagram). The present trend seems to be pointing towards a sort of reunification of the two original branches, which will probably return to walk together, as the recent developments in bionics and in neural networks strongly suggest. Nowadays the investigation of these fields has just started, but even so a number of analogies have been discovered between the operation of an information processing system and the behavior of the human nervous system. As a direct example, in both cases the exchange of information takes place by means of a binary code, as can be seen in the electrical behavior of a single cell. Nevertheless, in certain cases an external electrical current passing through the human body can deeply alter vital functions, and have devastating if not lethal effects. The different issues are discussed through a unifying theory, which takes together both the electrical and biological aspects, highlighting the specularity of the two phenomena.






Analytical modelling and investigation of the adjustable speed drive

performance under input voltage unbalance


Professor Jiri Klima

Dean of the Technical Faculty of CZU in Prague

Czech Republic



Abstract: Adjustable speed drives are widely used in industrial applications as the most efficient means of achieving motion control.Input voltage unbalance and sag conditions can have serious consiquences on performance of induction motor drive.

One of the most harmful performance effect is torque pulsation (ripple torque) that are dominated by the second harmonic of the input line frequency (50 or 60 Hz). The paper presents the mathematical model enabling the closed-form solution of the motor currents and electromagnetic torque under this unbalance input voltage. The model is based on the mixed p-z approach. The analytical results can be used as a valuable design tool evaluating the impact of input voltage unbalance. 






Wind Power and the Impact on Power Systems


Professor Terje Gjengedal

NTNU & Statkraft

P.O.Box 200, Lilleaker, 0216 Oslo, Norway



Abstract: Wind Power is among the fastest growing energy source in the world. In most systems, the amount of wind power integrated into large scale electrical power systems only covers a small part of total power systems load. With a low wind power penetration, system impacts are normally small and wind turbines normally do not take part in voltage and frequency control and if a disturbance occurs, the wind turbines are normally disconnected and reconnected when normal operation has resumed. That is, frequency and voltage are maintained by controlling the large power plants as would be the case without wind turbines present.

In systems with a large portion of wind power the wind turbines and wind  electric system may begin to influence overall power system behaviour, making it difficult to operate by only controlling large scale power plants. Therefore, when considering establishment of large wind power plants, several questions must be clarified. This includes transmission capacity, frequency and voltage stability, frequency control and reserves, and in some cases also flicker and harmonics. Detailed system and design studies must be carried out in order to find the best technical-economical solution for dealing with these issues. Large scale wind power may also bring substantial operational effects due to balance management and reserve impacts.

Therefore, grid codes are now developed that defines the dynamic and static requirements wind turbines must meet in order to be connected to the grid. These requirements may in some cases  be troublesome and difficult to fulfil. Examples on such requirements are capabilities of contributing to frequency and voltage control by continuous modulation of active power and reactive power supplied to the transmission system.

The speech will discuss these issues with the main focus on system operation, control and stability and it will be related to the abovementioned issues of system integration, power system impacts and future grid code requirements. It will provide a structured presentation of the principles, status and experiences of wind power in power systems. Examples and experiences will be discussed and presented.

Information technology and a meta-learning environment


Professor Seppo Sirkemaa

Turku School of Economics, Pori Unit

P.O.Box 300, 28101 Pori, Finland



Abstract: Advancements in technology provide new tools for educators and students to be used in the learning process. Today students need to be skilled computer users and able to deal with different types of media in order to study effectively. However, technical expertise alone is not enough - one must know what to study, where to find information, what to do next etc. Therefore special attention is needed to orientate students to use technology so that they learn to study in a modern learning environment.

Here we argue that a meta-learning environment can help students in the learning process. A meta-learning environment is defined as a platform for studying and it should integrate technology and resources so that they empower the learning process.

A divergence operator to quantify texture from multi-spectral satellite images


Professor Jorge Lira

Instituto de Geofisica

National Autonomous University of Mexico

Cd. Universitaria, 04510 Mexico DF, Mexico



Abstract: A divergence operator to measure the texture content in a multi-spectral image is proposed. A multi-spectral image is modeled as an n-dimensional vector field, “n” being the number of bands of the image. A pixel of the image is an n-dimensional vector in this field. We demonstrate that the flux variations of the vector field are related to changes in texture in the image. A divergence operator measures the flux variation and hence, texture. In order to save computer memory, speed up the divergence operator calculation, and lessen the content of noise of the image, the principal components decomposition is applied to the bands of the image. The best three principal components are used to span the vector field. The partial derivatives involved in the divergence operator are written as weighted finite differences. To estimate these derivatives, cubes of three, five and seven voxels per side are considered. The cube is systematically displaced to cover the entire domain of the vector field. In each position of the cube, the divergence value is calculated using the weighted finite difference approximation. This value is written as a pixel in an output image file according to the cartesian coordinates defined by the location of the cube. This image file depicts the texture variations of the multi-spectral image. The relation: flux variation versus coarseness of texture is discussed. A detailed example, based on Landsat TM multi-spectral image, is presented and analyzed.
