Abstract: Experimental investigations of molecular dynamics at constant temperature for many-particle systems have been strongly influenced by introduction of the Nosé-Hoover thermostat dynamic's in 1980's. At low energy levels the dynamic behavior is known to be regular. At higher energy levels the regular motion is destroyed by perturbations, as follows from Kolmogorov-Arnold-Moser theory. The resulting chaotic behavior has traditionally been analyzed by means of the Lyapunov exponents. It will be demonstrated in the proposed contribution that such a behavior is typical for a broad class of interconnected oscillators with at least one non-linear element. A new concept of abstract state space energy for a broad class of dissipative system representations, including such as the recently introduced non-Hamiltonian Nosé-Hoover thermostat system will be presented as a limiting case too. The questions of system instability, dissipativity, conservativity, asymptotic stability, state and parameter minimality, and many other related structural properties, are traditionally described in physical terms and are known to be closely related to the total system energy evolution. In contrary, the presented paper deals exclusively with an abstract state space energy measure for a broad class of finite dimensional strictly causal systems described in state-space representation form. The resulting energy metric function is induced by the observed output signal power of an abstract dissipative system representation in such a way that a form of abstract conservation law holds. The concept of the state space energy is defined by power integration. Using abstract form of the energy conservation principle a specific structure of the corresponding class of physically correct
system representations is derived. The same technique is applied for continuous-time as well as for discrete-time systems. Some typical examples of linear and nonlinear causal systems are
investigated from the proposed state space energy point of view, too. The system simulation results will also be presented in the lecture. The obtained results of a number of simulation experiments are compared with classical dynamics based techniques as well as with recently published Nosé-Hoover dynamics related results.

Abstract: Impact measurement at an international project level supposes the use of an elaborated methodology, a coordinated team to implement, impact’s evaluation of such project and designated channels that distribute this evaluation. In order to correctly evaluate the impact, a project it should be divided accordingly to specific domains: environment, economic, social and specific field(s) to which the project is addressed. For example, CIVITAS SUCCESS project, by definition, represents a transport and mobility project and, in order to quantify the mobility impact for this particular project, in this paper, it will be considered specific transport indicators. The evaluation of a project impact and the dissemination of this impact are not meant only to add value to the project but to make it accessible and transferable to persons or institutions which intend to implement the same or a similar project.

Abstract: Time series forecasting, especially long-term prediction, is a challenge in many fields of science and engineering. Many techniques exist for time series forecasting. In general, the object of these techniques is to build a model of the process and then use this model on the last values of the time series to extrapolate past behavior into future. Forecasting procedures include different techniques and models. Although the search for a best time series forecasting method continues, it is agreeable that no single method will outperform all others in all situations. New developments and trends in the broad area of time series prediction based on fuzzy and neural networks will be reviewed in this talk.
A new method for the identification of an optimal set of time lags based on non-uniform attractor embedding from the observed non-linear time series is discussed. Simple deterministic method for the determination of non-uniform time lags comprises the pre-processing stage of the time series forecasting algorithm which is implemented in the form of a fuzzy inference system. Experiments done with benchmark chaotic time series show that the proposed method can considerably improve the forecasting accuracy. The proposed method is an efficient candidate for prediction of time series with multiple time scales and noise [1].
A near-optimal set of time lags is identified by evolutionary algorithms. The fitness function is constructed in such a way that it represents the spreading of the attractor in the delay coordinate space but does not contain any information on prediction error metrics. The weighted one-point crossover rule enables an effective identification of near-optimal sets of non-uniform time lags which are better than the globally optimal set of uniform time lags. Thus the reconstructed information on the properties of the underlying dynamical system is directly elaborated in the fuzzy prediction system. A number of numerical experiments are used to test the functionality of this method [2].
A new short-term time series forecasting method based on the identification of skeleton algebraic sequences is discussed in this talk. The concept of the rank of the Hankel matrix is exploited to detect a base fragment of the time series. Particle swarm optimization and evolutionary algorithms are then used to remove the noise and identify the skeleton algebraic sequence. Numerical experiments with an artificially generated and a real-world time series are used to illustrate the functionality of the proposed method [3].

KEYNOTE SPEECH: Finding Communities in Web-like Complex Networks

Abstract: Complex Networks such as the Internet, the World Wide Web (WWW), as well as various social and biological networks, are viewed as large, dynamic, random graphs, with properties significantly different from those of the classical Erdös-Rényi random graphs. One such property inherent to these web-like complex networks is the existence of communities. Mining for and identifying Web-based communities, for example, has an enormous potential for application. Therefore, communities have recently been explored in several disciplines—graph theory, physics, statistics, sociology, biology, and linguistics. A community may informally be defined as a locally-dense subgraph, of a significant size, in a much larger globally-sparse graph. An optimal extraction of communities has been shown to be NP-complete. We must, therefore, devise approximate algorithms. In this talk we will present a quick overview of the community-discovery algorithms and present new heuristic for community identification. That is, a new heuristic for identifying the community structure around a given set of seed vertices, using only their neighborhood information. Since identifying communities can be an extremely compute-intensive task, parallel computation has a critical role in the solution. We will discuss both sequential and parallel heuristics.

KEYNOTE SPEECH, New Generation HDMR Based Multiway Array Decomposers: Enhanced Multivariance Products Representation (EMPR)

Abstract: High Dimensional Model Representation (HDMR) was proposed by Sobol in the last decade of twentieth century and the research groups of Rabitz, and Demiralp, contributed to its development a lot beside some other scientists especially from India. It is developed to express a multivariate function in terms of components with ascending multivariance such that the first component is just a constant followed by univariate components each of which depends on a different independent variable, and the each coming group of components have increasing variance like bivariance, trivariance and so on. This works on multiway arrays also and the efficiency of the HDMR truncations at certain level of multivariance completely depends on how univariate the array under consideration is. There have been many attempts to increase the univariance and therefore truncation efficiency. During these efforts many descendants of HDMR have been developed. These will be given as much as the duration of the talk permits. Quite recently a new point of view has been brought to the scene to open new horizons for function or array decompositions by Demiralp group. The new method is not exactly an HDMR but its an extended form. It brings the concept of support functions which are in fact given univariate functions. The choice of these supports is a very important issue and can dramatically affect the truncation approximation. What we are going to present in this talk is based on cartesian geometry, hyperprismatic grids and regions at this moment. The purpose is get maximum contributions in at most univariate terms. This speech focuses on the issues roughly mentioned above in details as much as possible and tries to make comments and remarks on the possible pitfalls and misunderstandings. The talk sufficiently addresses to the related works emphasizing on the findings of the author’s and his group on this topics.

Abstract: In the proposed lecture a physically motivated signal-system-theoretic approach, based on a generalization of the well known Tellegen’s principle of electrical circuits will be presented. The most important feature of Tellegen’s approach is the fact that the energy conservation principle holds without any regard to physical nature of constituent network elements. This is the key idea of the proposed approach to problems of dissipativity and chaos. The lecture is motivated by some fundamental questions arising in theoretical analysis of linear and nonlinear state space energy exchange between two causal systems under a coupling nonlinearity, including a possibility of appearing chaotic dynamics. Knowledge of principles of nonlinear dynamics and synthesis of non-chaotic and chaotic attractors is found to be very important also for other potential applications, such as biomedical engineering, e.g. cardiovascular system modelling, encryption by secure communication, modeling of nonlinear phenomena in power networks, etc. This provides a strong motivation for the current research on exploiting some new chaotic attractors and their implementations.
An analog electronic circuit was designed and built to confirm typical behavior of a class of nonlinearly coupled non-chaotic and chaotic oscillators. It was explained theoretically, as well as demonstrated by computer simulation combined with laboratory experiments that some typical chaotic phenomena can appear as a consequence of irregular energy exchange between two coupled systems. In our experiments, the system consists of a 2-nd order nonlinear antidissipative subsystem nonlinearly coupled with a linear oscillator with dissipation. The part of experiment concern also synchronization of coupled non-chaotic and chaotic oscillators

Abstract: The Aim of the Work: This intrinsic analytic study was done with the aim of improving and enriching the knowledge about the local physical phenomena encountered in both fluid mechanics and magneto-fluid dynamics, elaborating a new physical & mathematical model of fluid flow and magnetic field, by using a special type of coordinate system. It continues a series of works presented by the author at the 5th WCNA and at some WSEAS conferences in 2008, representing a real deep insight into the still hidden theory of isoenergetic flow, this one being a lesser known domain in the physical sciences (approaching some new special topics in classical potential theory, fluid mechanics, aerothermodynamics and magneto-hydrodynamics, including plasma). So far, to the best of the author’s knowledge, nowhere in the world literature a method to obtain the general case of first integrability for the vector equations of motion has been considered, but very particular cases only. These include the vector equation of motion in the steady and unsteady inviscid (or viscous) fluid mechanics (D. Bernoulli and D. Bernoulli-Lagrange integrals), the vector equation of motion and the “magnetic induction” one in magneto-hydrodynamics, as well as the system of these two simultaneous vector equations in magneto-hydrodynamics. As its title shows, this work is fully original.
Key-Words and Phrases: rotational flows, steady and unsteady flows, virtual “isentropic” (Bernoulli’s) surfaces, inviscid and viscous fluids, compressible fluids, flow of an electroconducting fluid in an external magnetic field; Selescu’s vectors, space curves (vector lines) and virtual “zero-work” surfaces
2000 Mathematics Subject Classification: 31 Potential theory; 70 Mechanics of particles and systems; 76 Fluid mechanics; 78 Optics, electromagnetic theory; 80 Classical thermodynamics, heat transfer
Extended Abstract: A model of the isoenergetic flow of an inviscid fluid was introduced, in order to establish a simpler form for the general PDE of the velocity potential. It consists mainly in using an intrinsic system of triorthogonal curvilinear coordinates (one of them being tied to the local specific entropy value). The choice of this system enables the treatment of any 3-D flow (rotational, steady and unsteady) as a potential 2-D one, introducing a 2-D velocity “quasi-potential”, specific to any isentropic surface. The dependence of the specific entropy on this velocity “quasi-potential” was also established. On the above surfaces the streamlines are orthogonal paths of a family of lines of equal velocity “quasi-potential”. This model can be extended to some special (but usual) cases in magneto-plasma dynamics (taking into account the flow vorticity effects, as well as those of the Joule–Lenz heat losses), considering a non-isentropic flow of an inviscid electroconducting fluid in an external magnetic field. There always are some space curves along which the motion equation admits a first integral, making evident a new physical quantity – Selescu’s magneto-hydrodynamic vector $. For a fluid with an infinite electric conductivity (like highly ionized plasma), these curves are the flow isentropic lines, also enabling the treatment of any 3-D flow as a “quasi-potential” 2-D one. The model was extended to the viscous Newtonian fluid flows and to visco-magnetic flows of conducting fluids respectively, introducing some “zero-work” (for the non-conservative terms) surfaces, some new physical quantities – Selescu’s vectors (roto-viscous Ş, Şi, roto-visco-magnetic §, and magnetic Şm), new intrinsic coordinate systems, and a 2-D magnetic “quasi-potential”, searching for and finding first integrals for the motion equation in viscous fluid mechanics and in MHD, and for the equation of magnetic induction (separately treated), the last one in a similar way to the vortex equation for a viscous Newtonian incompressible fluid. The new model was analyzed in order to find a case of first integrability in MHD for the system of motion and magnetic induction simultaneous equations, establishing a special procedure for finding such first integrals. In almost all cases treated, the newly found first integrals are similar to D. Bernoulli and D. Bernoulli–Lagrange ones, being obtained by a procedure for eliminating the non-conservative terms in the respective equations. The PDE of the velocity potential, that of the isentropic surfaces, as well as those of Selescu’s vector lines and zero-work surfaces, were also given.

Plenary Speakers' Brief Biography: Dr.Richard Selescu graduated as an engineer from the Polytechnic Institute Bucharest, the Faculty of Mechanics, Department of Aircraft Engineering in 1970. He is working in the National Institute for Aerospace Research “Elie Carafoli’’ – INCAS, Department of Aerodynamics, at the Trisonic Wind Tunnel Laboratory. He received his PhD degree in Aerodynamics and Fluid Mechanics at the Aerospace Engineering Faculty of the “Politehnica” University Bucharest in 1999. Among the research fields of interest, he approached the analytic modeling in aerodynamics, fluid mechanics and magnetofluid dynamics. Thus, he introduced the following nomenclature: the isentropic surfaces and a 2-D velocity quasi-potential function on these surfaces (in fluid mechanics); the zero-work surfaces for the non-conservative terms in the motion equation (in viscous fluid mechanics and magnetofluid dynamics); some new physical quantities – the roto-viscous vector (in Newtonian viscous fluid mechanics), the incompressible roto-viscous vector (in viscous incompressible fluid mechanics, for the vortex equation), the magneto-hydrodynamic vector (in inviscid magnetofluid dynamics), the roto-visco-magnetic vector (in viscous magnetofluid dynamics) and the magnetic vector (in visco-magnetic magnetofluid dynamics, for the equation of magnetic induction); a new shock-free axisymmetric supersonic flow – the tronconical flow (in supersonic aerogasdynamics); the similarity depth for satisfying the gas-hydrodynamic analogy (in supercritical hydrodynamics).

Abstract: This lecture is an approach dedicated to the improvement and experimentation of several neural network pattern recognition models for satellite and aerial imagery. One considers the following neural network classifiers: Multilevel Perceptron (MLP), Radial Basis Function (RBF) neural net, supervised Self-Organizing Map (SOM), and the system of Concurrent Self-Organizing Maps (CSOM) . CSOM was previously proposed by the author of this lecture ; it is in fact a model of Concurrent Neural Classifiers (CNC) , representing a collection of small neural networks, which use a global winner-takes-all strategy. Each neural module is trained to correctly classify the patterns of one class only and the number of modules equals the number “M” of classes. One considers the case of choosing the SOM (Self-Organized-Map) as a neural module. We built “M” training pattern sets and each neural module is trained with the pattern set characterized by the corresponding class label. We have implemented and evaluated the above mentioned neural classifier models for two kind of applications. First application investigates multispectral satellite image classification for environment monitoring. The implemented neural classifiers are evaluated using a LANDSAT 7 ETM+ image. One takes in consideration both the interband and also the intraband pixel correlation of the 7-band image. There is a subset containing labeled pixels, corresponding to several thematic categories: urban areas, agricultural fields, woods, water, bushes, meadows and barren fields. The best experimental result is obtained by CSOM model and it corresponds to the recognition rate of 99.11 %. Second application evaluates the considered neural network models for Automated Target Recognition (ATR) based on spot Synthetic Aperture Radar (SAR) imagery. One uses the MSTAR (Moving and Stationary Target Acquisition and Recognition) database for three categories of military vehicles: BMP2 (Tank), BTR 70 (Armored car) and T72 (tank). The best performance corresponds also to the CSOM model and it leads to the recognition rate of 95.81%.

Abstract: In this Plenary Lecture, will be comment the some biometric approaches and its real possibility for its use on high and low security applications. The advances of multimodal biometric systems and the new biometric system allow its use in different scenarios. The unions of technology and the biometric business have increased its expansion. The use of biometric recognition systems has yielded significant progress in the last years. However, considerable advances on both system precision and cost reduction of sensors, has not produced an increase in user’s confidence, mainly due to lack of reliability in real operational environments, and also due to privacy and vulnerability concerns. In order to alleviate the problems generated by the adoption of biometric systems, which are in any case highly valuable for industrials, the innovative development of a biometric scheme is proposed; operating in realistic environments, the system will
incorporate the following features:
1. Multibiometric, incorporating three different perspectives: multimodal, multi-shot
and multi-level.
2. High transparency and acceptability, and low intrusiveness of the adopted
intra-modalities on hand-based biometrics, as far as users accept them as
being highly transparent, and do not require user cooperativeness, nor show
social refusal, as iris or fingerprints do.
3. Combined use of these intra-modalities in order to attain reliability comparable
to iris or fingerprint modalities.
4. Use of objective quality measures of the test sample, in order to weight the
multibiometric fusion process, inducing so an improvement in the
authentication rates.
5. Hardware and software development oriented to conduct match-on-card tests,

Abstract: Caffeine (CAF) is one of the most widely and regularly consumed biologically active substances. It acts as a stimulant of the nervous system. This is the reason for consumption by the most humans of various CAF-containing drugs and beverages. The structure of the caffeine molecule is relatively simple. CAF is a purine derivative, 1,3,7-trimethylxantine (1,3,7-trimethyl-2,6-dioxopurine). Besides its principal and rapid actions on nervous system CAF has an effect on various other biological processes, including those related to functioning of DNA and some enzymes. In spite of the simplicity of molecular structure and the importance of biological effects of CAF, detailed atomic level mechanisms are unknown for both the main and lateral effects of CAF and related compounds. We use computer simulation approach to the study of CAF activity by searching for its possible complexes with biopolymer fragments. Molecular mechanics is the principal method for the calculations of the energy of interactions between CAF and the biopolymer fragments. More exact and having more physical basis quantum mechanics methods are possible for considerations of CAF interactions with rather small molecules only. The energy minimization enables us to suggest the most favorable configurations of the complexes; the use of Monte Carlo sampling provides us with the most populated by CAF regions of the biopolymer surface and with mean energy and structure characteristics of the complexes. Earlier we considered molecular mechanisms of CAF interactions with DNA fragments in relation to its “lateral” action on genetic processes. Computer simulation enables us to explain CAF influence on DNA repair and DNA-drug interactions. Recently we started computational study of the main CAF action [3]. The principal CAF target at physiologically important concentrations refers to adenosine receptors. It is a common opinion that CAF is a competitive antagonist of adenosine. At the first step to molecular level elucidation of CAF action, we have found a set of the minima of the interaction energy between CAF and the fragments of human A1 adenosine receptor. It appears that the deepest minima refer to H-bond formation of CAF with amino acid residues involved in interactions with adenosine, its agonists and antagonists. The results suggest that the formation of CAF-receptor H-bonded complexes enforced by a close packing of CAF and the receptor fragments is the reason of CAF actions on nervous system. CAF can block the atomic groups of the adenosine repressors responsible for the interactions with adenosine, not necessary by the formation of H bonds with them, but simply hide these groups from the interactions with adenosine. The computer simulation will help us to answer the next question: “Why such rather small molecule as CAF with restricted set of centers of sufficiently strong interactions can compete with larger molecules capable to form potentially more stable complexes?”

Abstract: Formal methods--be they logical (such as model checking) or algebraic (such as model-based testing)--have established themselves as mainstream tools for verification and validation. Hardware, device drivers, and network protocol have all been formally validated in various contexts. Recent Turing prizes have recognized this success. When it comes to specifying and verifying complex application software, formal methods have hit however a stumbling block. Indeed, conformance testing is traditionally based on finite-state formalisms: a system is at any time in one of the multitude of named states. Such an approach fails for complex software because of the sheer number of necessarily distinct states (already happening in simpler systems, but becoming simply unmanageable for complex applications such as word processors or operating systems). Bringing conformance testing to complex application software is an emerging area. Typical programming languages (and thus the control flow of software programmed using them) feature nested, recursive invocations of program modules. These features are modelled naturally by context-free languages. Many non-regular properties are therefore required for software verification. Such properties generate an finite state space, which cannot be handled by finite-state process algebrae or by standard verification techniques such as model checking. Context-free process algebrae such as BPA can specify context-free properties. However, concurrency cannot be provided by context-free process algebrae since context-free languages are not closed under intersection. This talk focuses on the quest of finding a formalism that is expressive enough to model the context-free phenomenae from complex software yet allows for a compositional approach to conformance testing. We start with visibly pushdown languages (VPL), a promising construct which unfortunately is not suitable for compositional specification and verification. We extend VPL to multiple stacks, obtaining multi-stack visibly pushdown languages (MVPL). These languages model concurrency naturally, but their standard definition does not allow compositional approaches. We then present an alternate set of operations over MVPL that are natural and also permit compositional specification and verification. The subsequent tools for specifying complex, recursive application software will also be discussed.

Abstract: Mathematical models are used to forecast new product sales. Forecasting using mathematical methods have been criticized by many researchers, as the forecasts are often not sufficiently accurate to
be applied to business decisions. Forecasting new product sales may be improved by using intuitive techniques. In this paper intuitive techniques are applied to mathematical forecasting models. A growth curve predication model is developed; in addition a reference data set is used to validate the outputs, providing important lessons for managers.

Abstract: Rules by which societies govern themselves are called institutions. Institutions can be political, economic, social, but generally they are a complex combination of these. Universities and academies of higher education frequently offer courseware on 'Political Engineering'; the title has an interdisciplinary flavor, suggesting some kind of engineering applied to political science. When you proceed from heading to subject, you find tools of economic theory, game theory, social-choice theory and formal logic used in ample. There is everything but engineering! This lecture is the first bold attempt to apply genuine methodologies in mechanical engineering design to Governance. Hence I define this created subject as ‘Genuine Political Engineering’. The paper revolves around the solution to a complex problem: comparing the size of a road roller required resurfacing a road most efficiently with the number of elected representatives required ruling a population (in a country or state) most effectively. The solution emerges in the shape of a sophisticated software that I call "political machinery'. This research is aimed to compel a sizeable percentage of conventional political pundits and exponents of sustainable living to conclude that governance can be bettered by employing machine designers to assist parliamentarians-turned-policy makers. Perhaps, the phrase, political machinery, wants to live up to its technically oriented name.

Abstract: In the speech is presented a generalized method to determine the performance of different types of heat exchanger starting from the behaviour of different Elementary Heat Exchanger (EHE), as part of an assembly. Algorithms, with computer aided analyse and application in the specific case of heat pipe heat exchanger (HPHE) is presented, also. The EHE (the Heat Pipe in the case of HPHE) has a self performance depending on the different operating conditions. Inside the heat exchanger, usually, we have a combination of the EHE in a parallel, a series or a mixed arrangement. The performance (behaviour) of each EHE depend, essentially, on the position inside the exchanger, taking in account that the temperatures of both fluids are variable in the longer of the exchanger. Finally, the overall performance of the exchanger is a sum of the performance of the total number of EHE. The algorithm to predict the performance oh HPHE is based on the knowledge of the behaviour of EHE in very different conditions (behaviour obtained by laboratory tests) and on the use of a specific software, which is presented more detailed in the lecture.

The Overview of SC Macrodiversity System Second Order Statistics Operating over Shadowed Fading Channels

Abstract: Wireless channels are simultaneously affected by short-term fading and long-term fading (shadowing). While short-term fading is mitigated through the use of diversity techniques typically at the single base station (micro-diversity), use of such microdiversity approaches alone will not be sufficient to mitigate the overall channel degradation when shadowing is also concurrently present. Since both short- and long-term fading coexist in wireless systems, we must simultaneously take their influence into account. Macrodiversity is used to alleviate the effects of shadowing, where multiple signals are received at widely located base stations, ensuring that different long-term fading is experienced by these signals. The simultaneous use of multiple base stations and the processing of signals from these base stations will provide the frame work for both macro and micro-diversity techniques to improve the performance in shadowed fading channels. At the macro-level, SC is basically a fast response handoff mechanism that instantaneously or, with minimal delay chooses the best base station to serve mobile based on the signal power received. The level crossing rate (LCR) and the average fading duration (AFD) are second-order statistical quantities, which complement the static probabilistic description of the fading signal (the first-order statistics), and have found several applications in the modelling and design of practical systems and designing of wireless communication systems.
The second order statistics of SC (Selection Combining) macrodiversity operating over the Gamma shadowed fading channels are derived. The macrodiversity system of SC type consists of two microdiversity systems and selection is based on their output signal power values. Each microdiversity system is of SC type with arbitrary number of branches in the presence of various types of short time fading. The short-term signal variation is described by several distributions such as Hoyt, Rayleigh, Rice, Nakagami-m, α-μ and Weibull. This range of short-time fading distribution includes all important fading phenomenons. Considering Nakagami-m and Hoyt distribution multipath scattering with relatively large delay-time spreads, with different clusters of reflected waves are described. In that way good fits to collected data in indoor and outdoor mobile-radio environments are provided. Also the consideration of propagation paths, consisting of one strong direct line-of sight (LoS) signal, and many randomly reflected, usually weaker signals is included trought the Ricean distribution. The non-linearity fading effects are included trought consideration of Weibull and α-μ fading distributions. Since base stations at the macrodiversity level are widely located, due to sufficient spacing between antennas, long-term fading is moddeled with joint distribution of two statistically independent Gamma distributions.

Abstract: Indoor Air Pollution (IAP) describes the adverse ambient air conditions inside households, schools, places of work and other indoor spaces. This can be caused by a range of sources, including stoves, smoking, consumer products, furnishings, infilteration of outdoor air and machinery etc. Air pollution has become a major concern in India in recent years both because it is now clear that large parts of the Indian urban population are exposed to some of the highest pollutant levels in the world and also because new studies around the world on the health effects of air pollution have increased confidence in estimates of the risks posed by air pollution exposures. Most IAP issues studied in the developing world including India focus on combustion of coal, wood and other biomass fuels. Pollutants focused are mainly PM10 and PM 2.5. Very little work has been done on monitoring of VOCs in indoor of Indian urban cities. Limited studies carried out indicate high levels of VOCs in indoors. Sufficient data is available to categorise VOCs as a pollutant warranting control in indoor environment.
More than forty VOCs have been identified in variety of indoor environment viz residential, food court, theater, conference hall, library, offices, restaurant, bar, class rooms, bank and printing press in Mumbai and Kolkata. One fourth of these are Hazardous Air Pollutants. The exposure risk and Hazard Index has been estimated to be greater than 1.

Abstract: For the rapid shift of our society to the longevity and little birth rate, we discuss the possible contribution of communication environment based on information technology to the better living arrangement of the elderly, the handicapped, the sick, the healthy and so on. The information systems based on the same principle combined with a newly developed button type simple computer for definite inevitable functions are introduced as a unified system. It was particularly designed not only for everyday life convenience but also for sudden illness threatened to life for the lonely living persons. The unified system works on the basis of its safety, reliability and flexibility, reflecting limits and vulnerability of past technical achievements in wellness and well-being. We emphasize the importance of wide area networks, considering its easy replacement and convenience for public benefits, including favorable economics and easy-to-handle equipment, as systems boasting both high-tech and multiple functions in a single apparatus do not necessarily lead to widespread use. Hereby, the active use of the Internet environment is also mentioned for the wide provision of convenience on public benefits. Various appropriate systems as variations on the basis of same principle are presented for the help of guidance, health care, nursing and medical affairs, physical exercise, amusement, rehabilitation, social participation and so on. The proposals on policies aimed at hardware development, software improvement and system management, which can help better use of these networks with technical viewpoints and equipment derived from our trials with comprehensive engineering issues related to developing and practical utilization of basic functions. In addition, beneficiaries themselves cover effective activity and communications in remote islands and/or depopulated area, where sufficient resource of welfare staff might not be provided including the definite intercommunication of persons at a distance. Although our argument and views cover some, not all, pertinent aspects, we try to illustrate and advocate the roles and possibilities that we can play in wellness and well-being. Thus, we provide appropriate means of communication not only for everyday life support of beneficiaries with closely related persons such as family members, but also for substantial support of welfare staff such as helper, caretaker, nurse, health nurse and physician. Consequently, the basic posture of proposed system relating to current information technology leads us to the intended build-up of new future welfare culture.

Abstract: The main purpose of projects co-financed by European Community is to enhance the life of European citizens by implementing measures with immediate or long term effect. One of the main sectors targeted by the EC projects is the transport sector. The transport sector plays a critical role in modern economies, but the sector also accounts for an increasing share of energy end use and gaseous emissions. In the European Union the proportion of energy used by transport accounts for 29%, industry consumes 32%; and residential and other sectors the remaining 39%. Land transport accounts for 86% of total EU consumption in the transport sector, and almost all the energy used is in the form of oil products. This presents a challenging problem as regards security in energy supply. More than 80% of EU citizens live and work in cities, and it is here that the environmental problems caused by the transport sector become most acute. Irrational use of energy combines with environmental degradation, which in turn is linked to increasing traffic congestion. Program CIVITAS II specifically calls for the use of technologies, which are developed but not yet mainstream and the focus should be on short/medium term alternatives, i.e. innovative bio-fuels and natural gas, including hybrid vehicles that use these fuels. SUCCESS (Smaller Urban Communities in CIVITAS for Environmentally Sustainable Solutions) contributed to the implementation of many of the EU's policies, especially environment, energy and transport. It also answers to various questions of European wide interest and of strategic importance.

Abstract: In a previous paper H.Nishino, H.Miki and the author have constructed 2-dimensional duck solutions in Goodwin's economic model modifying the effective function. In another one, we got 4-dimensional ducks in a trading economic model using two symmetric Goodwin's models. These results lead us a new point of view to analyze the stability for the ducks. In the $R^{2+2}$ slow-fast system with an invariant manifold, we first assume that this manifold describing limit cycle has a duck solution in a projected $R^{2}$ space. If there exists pseudo singular node point near the invariant manifold, the system has a duck solution with a relatively stable region in $R^{4}$. This fact gives a global behavior in $R^{4}$, because it satisfies the condition including the invariant manifold at around the pseudo singular point. In other words, we can observe a center manifold for the slow-fast system in $R^{4}$.

Abstract: There are 2000 thunderstorms in progress at any time resulting in 100 lightning flashes to ground per second; this is 8 million per day. It causes of 24000 lightning deaths and other 240000 are injured per year. These data proves the critical needs for lightning protection system. In general, there are a lot of issues with regards to the selection of proper lightning protection systems. From the time of the first installation to the present day, characterization of the effectiveness remains a recurring question. Sustainability is an important criterion in ensuring the chosen protection system is governed by the international standards and of course technically and scientifically proven in effectiveness. The development of lightning protection principle throughout the world is based on solid science. Any scientific method can be summed up after the theory is formed, tested and conclusion is drawn. For the past 250 years, the lightning protection systems have been intensively studied and have been proven effectively many times. Field data recorded provides provide conclusive evidence that conventional lightning protection systems can provide substantial reduction in lightning-related incidents. The data clearly demonstrates the validity of the basic technology when the requirements are properly applied and adequately maintained. Therefore, the questions of what, why, when, where and how are remains valid towards achieving the best practice in lightning protection system.

Abstract: - Parametric control of the processes in continua is of interest both for the development of the theory, as well as for the practical applications in diverse technical and technological processes and systems. For example, parametric excitation of oscillations at the interfaces in continua may intensify various technological and technical processes (heat and mass transfer, mixing of different liquid components, decreasing viscosity and conductivity of media, improving a quality for crystallizating metal and many others). Then, the excitation of parameters’ oscillations is used for disintegration of the jet and film flows in the processes like spray-coating, metal spraying, granulation of materials, and so on. The opposite task is a suppression of the oscillations in a problem of stabilization of the unstable boundaries, or regimes and processes. What is more, parametric control in a number of highly effective intensive thermal, electromechanical and electrochemical processes makes possible to run even the unstable modes, which are impossible to have without proper control.

Abstract: This paper presents a software application called Admission-Discharge-Transfer (ADT) Gateway Interface. This interface uses the Health Level 7 (HL7) standard to bridge the hospital computer systems for maintaining hospital bed occupancy. ADT Gateway Interface is a Microsoft VB.NET application that utilizes the Microsoft Windows TCP/IP socket to communicate with the Hospital Information System (HIS) ADT System. Received messages are processed using a custom Microsoft Windows DLL called HL7Messaging DLL and information presented inside these messages are put into a Microsoft SQL Server 2005 database. Hospital computer systems reach to this SQL Server 2005 database to examine the bed occupancy in the hospital. Furthermore, states and errors of this ADT Gateway Interface are recorded. This helps design engineers in measuring performance and observing failures and recoveries. This may require detailed log information from this application. In this study, a robust logging viewer design methodology is used to improve reliability and consistency of the overall integrated system.

Abstract. Such processes are widely used in Engineering Sciences, Biology, Insurance, Inventory Theory and so on. After describing mathematical models, we shall present a series of meaningful examples. One of the most powerful methods of obtaining an optimal control strategy is Dynamic Programming. Another modern method of attack is so called Convex Analytic Approach. In this lecture the both methods will be briefly discussed. The second half of the lecture will be devoted to more special models. First, we concentrate on the processes with local transitions, like birth-and-death processes. They are known to be successfully approximated by deterministic differential equations under so called ”fluid scaling”. New results on the accuracy of such approximation will be presented. Secondly, a new look at the well known ”C-mu-rule”
in the Queuing Theory will be discussed: we shall compare the stochastic and deterministic versions. Finally, we shall stop on applications of the theory to the optimal buffer sizing for Internet routers. The last several minutes will be devoted to more general models, open questions and new challendging real life problems.

Abstract: The effect of resonant absorption of long waves by the oscillator of little gabarits is investigated analytically and numerically. This effect means that absorption cross-section of the oscillator (monopole, dipole...) is defined by wavelength absorbed only, and does not depend on wave dimensions (much smaller, than the wavelength absorbed) of the oscillator. The expression of optimum amplitudes of excitation of the group of degrees of freedom (or oscillators) in the boundary problem of general type is obtained in the form of generalized velocities and generalized forces. Using the linear microstructures (formed by monopoles, which are located on the axis periodically) we investigated the possibility to achieve the maximum absorption cross-section of the acoustic waves by these microstructures of small wave dimensions. We consider the examples of linear microstructures, which provide unlimited logarithmic, linear and square growing of the total absorption cross-section, with growing of the quantity of elements (monopoles) in the linear microstructure with wave dimensions remaining small. The examples of cooperative and the individual strategies of absorbing oscillators are compared too. The results obtained can be used for another waves: for electromagnetic waves, water surface waves, waves of bending in elastic plates, etc...

Abstract. The focus of this presentation is to enhance the way of thinking that human activities cannot be separated from the functioning of the entire system on Earth. Learning from the Nature means to accept that the technical systems processes involving energy conversion and matter transformation need to be linked to environment engineering. An approach within the Industrial Ecology framework of technical systems (created by humans) and ecological systems (created by Nature) as parts of the same system, the industrial ecosystems, could provide a holistic view of the interactions and symbiosis interrelationships among human activities, industrial practices and ecological processes. Although Science not clarified and unified technical and ecological viewpoints, a set of conditions for the performance of sustainable electrical systems should be formulated. This presentation goes on to adopt a dualist view, incorporating technical and environmental dimensions, to describe exergy applicability to electrical ecosystems. Drawing up a description of the electric system as an industrial ecosystem, with its limits and components, defining the systems operation regimes and assessing the equilibrium points of the system within the two reference frames represent the appropriate steps of the industrial ecosystem metabolism analysis.

Abstract: This work proceeds a study of the national transport sector, for the fuel consumption and possible alternatives for the long term, in relation to the adoption of the Monte Carlo Model simulation. Through data collection and the selection criteria related to the problem are proposals and optimized objective functions, aiming to maximize and minimize the National GDP and the GDP of Transportation. Certain restrictions apply, involving road, rail, sea, air, demand versus fuel consumption and implicit economical variables, all in an optimal condition. Based on the obtained results, the influence of each constraint in the objective functions are analyzed, seeking the best scenarios and long-term strategies. Through sensitivity analysis, whose visualization is made possible by the use of linear programming methods and computer systems available look for and reveal trends of the array for transport and dominant energy source. Therefore, data analyses, obtaining results from the simulation models, are revealed essentially to clarify the long-term behavior for different values of the mathematical model proposal.

Abstract: In an ever-developing society, a strong, viable economy is vital for any country that seeks to survive on the global market and to provide upwardly living standards for its citizens. Recognizing the above mentioned points as mandatory, Romania is taking steps to develop its electronic banking services to meet 21st century global standards. The eBanking services gained the attention of a major part of the traditional banking services customer because of the great importance of the financial activities within the daily life. This must be a plus for the bank, but this hypothesis is not confirmed by the real life. The paper identifies the factors that influence the customers’ intention to use the electronic version for banking services . The user acceptance of Internet as new technologies that transform some traditional services and activities is a topic of interest for many professionals and researchers working in various domains. This paper presents the main theories employed in assessing the technology acceptance (theory of reasoned action, theory of planned behavior) as well as the technology acceptance models that have been developed on the basis of these theories. The focus of the paper is on the model develops and, implicitly, on the hypotheses that have to be tested in order to validate a model for the Internet acceptance in traditional banking services, based both on the content of the main theories employed in assessing the technology acceptance as Information Diffusion Theory, Trust, Technology Acceptance Model, Decomposed Theory of Planned Behavior and empirical studies, too.

Abstract: This paper presents some considerations on the applications in environment monitoring based on some concepts as: estimation, fault detection and diagnosis, theory of distributed parameter systems, applied to the physical processes from the environment, artificial intelligence, with its tool adaptive-network-based fuzzy inference and the intelligent wireless ad-hoc sensor networks. The environment may be seen as a complex ensemble of different distributed parameter systems, described with partial differential equations. Sensor networks have large and successful applications in monitoring the environment, they been capable to measure, as a distributed sensor, the physical variables, on a large area, which are characterizing the environment and to communicate at long distance the measured values, form the distributed parameter environmental processes. Using the modern intelligent wireless sensor networks multivariable estimation techniques may be applied in environment monitoring, ting distributed parameter systems. Nbase o these concepts environment monitoring becomes more easily and more performing. The paper presents some applications in environment monitoring, based on artificial intelligence, allowing treatment of the large, complex, non-linear and multivariable system of the environment by learning and extrapolation.

Abstract: Nonidentical Josephson junctions (JJs) coupled via a high resistance Rcp is considered under the excitation of dc sources. Initially, an analytical model is constructed in terms of several first order differential equations following a nonlinear resistive-capacitive shunted junction (NRCSJ).Then, the properties at an equilibrium point is investigated and a transcritical bifurcation is observed as a result of a center manifold analysis. Both periodic and aperiodic behaviors are encountered depending on the circuit parameters. It is proven that, the coupling resistance Rcp, the excitation amplitudes Ii and internal junction parameters such as Ri and Ci play important roles in order to depict the overall dynamics.

Current Measurement Trends in Financial Reporting: From Historical Costs towards Fair Value Concept (and Back?)

Abstract: Measurement in financial reporting is one of factors which determines the quality and reliability of presented information. There may be seen a conflict between the requirements for relevance and timeliness of measurement on one side and the reliability and conclusive evidence on the other side. However, it shall be stated that the important problem of measurement issues is the possibility of subjective manipulation with values, which is possible when using certain measurement bases.

Upon economic boom there can be seen higher optimism of investors which leads towards requirement of measurement of all accounting items at fair value, which mainly represents current market prices of assets. Using this concept means the turn from the prudence principle and conservative historical costs concept in financial accounting. Moreover fair value concept in financial accounting leads to higher tendency of revaluation assets or liabilities affecting profit or loss of the company.

Upon recession users revaluate their views on accounting methods, especially the measurement bases. When we try to find out the reasons of economic crisis, we can hear opinions that it was very optimistic information given by fair value accounting in the period of economic boom. Current economic crisis may evoke the renaissance of conservative approaches in measurement, especially the applicability of prudence principle. Confidence in financial market upon crisis is thrilled; there can be seen strong price swings.

Abstract: Today, companies are facing with the process of sustainable development. We believe that only the companies which will implement interchanges of organisational renovation from the environmental viewpoint will be able to offer holistic environmental answers to the customer’s needs and their preferences. For that reason it is important that company retains its ability of ongoing monitoring of organisational model of viewpoints of environmental management. High quality environmental information is indispensable for responsive and cost-effective policies. The OECD provides leadership in the development of indicators to measure countries' environmental performance and provides harmonized data on environmental progress in OECD countries. It advises on methodologies for environmental indicators and accounting systems; it issues recommendations that help countries improve their environmental information systems and produce reliable environmental data . The purpose of this contribution is to study and define the most important indicators influencing environmental management effectiveness and efficiency in enterprises, focusing on Slovenian enterprises. The focus is on environmental indicators as the result of environmental management, environmental policy and a strategic direction towards achieving environmental goals as well as constant and continuous training and awareness-raising in stakeholders, employees, customers, suppliers and wider social community.The research objective was to set or determine and prove the role and significance of environmental management indicators in an enterprise's operations. The reflection included interdisciplinary thinking which enables us to understand and manage the process of environmental management in terms of sustainable development. Based on the assumption that an enterprise respects and complies with environmental legislation, it was analitically examined what types of environmental indicators and measures contribute to a constant and continuous improvement in terms of sustainable development. Environmental indicators are powerful tools that serve many purposes, useful as tools for performance evaluation and public information. The development of indicators is a dynamic process that is constantly subject to updating and improvement.

Abstract: Derivatives are at the very heart of the recent financial disasters, and the surveillance of

their downside risk is of paramount importance both to practitioners and regulators. We survey and present original managerial methods to efficiently control the downside risk of derivatives portfolios. We first describe the managerial methods currently used in practice and their relative cost, and we then show that the most common methods actually aggravate this downside risk. We then argue that selecting appropriate underlyings satisfying some specific statistical and
easily identifiable properties is a natural way to significantly reduce the downside risk without involving costly managerial interventions.

Abstract: In Romanian public policy there is a lot of talking these days about the inefficiency of the educational institutions and the need for an educational system reform. We think that an important part of this national problem is the deficient organizational culture of each educational institution. The lecture presents the results of a research study that aimed to identify the type of the organizational culture existent in a Romanian state university, the way it is perceived by the employees, and identifying the type of the organizational culture wanted by the employees. We also evaluated the work motivation, emphasized the association with the type of the organizational culture and the correlation between a series of classificatory variables and the perception of the organizational climate. The research sample included a number of 102 university teachers, aged between 25 and 57, from assistant professors to full professors. We used two measures: ESA Questionnaire (Ciucurel, 2006), for evaluating the work motivation, and Organizational Culture Questionnaire (Harrison, Stokes, 1992). The results showed that the main organizational culture existent was the power type and that the employees hope for a support type. In what concerns the work motivation, teachers from the university had a high self-actualization motivation.
