This paper offers a comprehensive study of information aggregation in intelligent systems prompted by common engineering interest. After a motivating introduction we consider aggregation functions and their fundamental properties as a basis for further development. Four main classes of aggregation functions are identified, and important subclasses are described and characterized as prototypes. For practical purposes, we outline two procedures to identify aggregation function that fits best to empirical data. Finally, we briefly recall some applications of aggregation functions in decision making, utility theory, fuzzy inference systems, multisensor data fusion, image processing, and their hardware implementation. © 2012 Elsevier B.V.

The main aim of this paper is to review of the current state of energy systems in the Western Balkans countries. The paper gives a review of the individual parameters relating to energy development, defines the current state of the achieved level of sustainable energy development as a whole and defines possible strategic directions for energy development in the region. The paper also examines the possibility for implementation of the adopted EU target of 20% RES energy production. The main characteristics in the region are high energy consumption, high values of carbon emission, fossil fuels import dependency, constant production and electric energy supply, and high potential but minimal RES energy production. Further development of regulation framework and market liberalization is are basic preconditions of demanding energy reform in all countries. Increasing energy the second energy development priority. The third long term strategic goal is increasing the amount of the energy obtained from hydro and transition to clean coal technologies. Intensifying RES production is currently the fourth strategic priority. The analysis shows that production of energy from wind is priority for the region, but currently it is constrained by too great investment requirements for developing countries. © 2012 Elsevier Ltd.

The need for preservation and adequate management of the quality of environment requires the development of new methods and techniques by which the achieved degree of sustainable development can be defined as well as the laws regarding the relationship among its subsystems. Main objective of research is to point to a strong contradiction between the development of ecological and economic subsystems. In order to improve previous research, this study suggests the use of linear evaluation, by which it is possible to determine the exact degree of contradiction between these two subsystems and to define the regularities as well as the deviations. Authors present the essential steps that were used. Conducted by the method of linear regression this research shows a significant negative correlation between ecological and economic subsystem indicators, whereas its value R2 0.58 proves the expected contradiction that exists between the two previously mentioned subsystems. By observing the sustainable development as a two-dimensional system that includes ecological and economic indicators, the authors suggest the methodology to modelling the relationship between economic and ecological development as an orthogonal distance between the degree of the current state measured by the relation between economic and ecological indicators of sustainable development and the degree which was obtained in a traditional way. The method used in this research proved to be extremely suitable for modelling the relationship between ecological and economic subsystems of sustainable development. This research was conducted on a repeated sample of countries of South East Europe by including the data for France and Germany, being two countries on the highest level of development in the European Union. © 2010 Elsevier Ltd.

For transport purposes a great amount of fossil fuels is exploited which represents the biggest threat to global warming and the realization of sustainable development concept. European Union is trying to implement and plan this concept on the entire European continent. In order to manage the sustainable development strategy, it is necessary to conduct an all-inclusive analysis of the current state and depending on the results, set some goals and define the activities that will make their realization possible. This research is based on the analysis of the waterway transport on Danube River and its aim is to point out the facts, based on which it will be possible to predict further directions of sustainable transport development on the most important waterway of Europe. The research indicates the basic rules of European politics of sustainable inland waterway development. The River Danube is considered to be the backbone of water transport in Europe. It connects, via Rhine - Main Canal, Western Europe and Rotterdam harbor with the Black Sea, that is with Russia and the East. The authors also analyze the data about the use of Danube waterway for transport of goods and people. This research covered a short description of Danube, the analysis of Danube fleet, the analysis of the amount of transported goods and number of transported people as well as the analysis of load and unload of goods in Danube harbors. The research covered these points in the period starting from the year of 1950. Based on the result analysis the authors arrived at a conclusion that the use of River Danube for waterway transport purposes is unsatisfactory and that as such cannot be sustained in long term. Also, the research points to the basic European initiatives and investment projects in the field of river transport which is in implementation stage. Considering the basic regulation documents and research results, the authors present an overview of measures and suggestions for efficient management conducted so far, development of a unique information system and promotion of Danube waterway, which will lead towards long-term sustainable development transport on Danube and so it will stimulate a stable and sustainable development of all countries and regions in Europe. © 2010 Elsevier Ltd.

Main problem addressed in this paper is assessment of quality of current methodologies for expressing environmental tax revenue, since measurements' outcomes have significant influence on the future environmental policies and legislation. The main goal of this paper is to analyze the existing way of measuring financial effects of environmental taxation in EU27 and propose new methodology approach, based on use of ETE - Environmental Taxation Efficiency as a new indicator suggested by authors. The first phase of the study involves the analysis of quality of measuring two existing methodologies (based on the use of GDP and total revenues). In second research stage, the authors apply the newly proposed methodology for determining a composite ETE indicator that, apart from existing indicators, takes into account the environmental taxation effects per capita, as an indicator unjustifiably neglected in previous methods of measuring. Measurement of environmental taxation by using a newly-proposed composite indicator shows significant differences in ranking compared to two current methodologies in use. Only 6 countries showed a very similar rank, regardless of the methodology applied. Differences by more than ten ranking positions were found in 12 countries. The overall results showed significant differences in ranking of all EU-27 countries by using all four indicated methodologies, which clearly points to the conclusion that further improvements are needed. ETE methodology limits predominant role of GDP and introduces a social component which should serve as a basis for further development of a unique methodology for establishing efficient environmental taxation implementation. © 2014 Elsevier Ltd.

Problems of sustainable development in connection with the change of biogeochemical cycle of selenium and overcoming its deficiency in Russia, Serbia, Belarus and other countries are reported. The history of the biological role of selenium as an essential trace element is discussed. A special program of «Overcoming of selenium deficiency» has been developed by researches of Russia, Serbia and Belarus in view of high morbidity rates for cardiovascular, tumor and endemic diseases affecting the population of both the above and some other countries, including children, prevalence of selenium deficiency among livestock species and aggravation of the environmental situation as a result of man-made processes. © 2010.

This paper tests and analyses the interdependence of financial markets in the transition economies of Serbia, Hungary, Croatia and Slovenia, as well as the similarity of these markets with the US financial market. The source of information is the data obtained from the financial markets of these countries in the form of stock-market indices for the period 05.10.2005-30.09.2011. The main hypothesis to be tested in the work is the assumption that there is a significant level of similarity between these financial markets. The methodology used in the study includes statistical methods of sampling and factor analysis. The research results confirm the hypothesis, which was tested in the work, that there are significant levels of similarity between the financial markets of transition economies, both among each other and with the US market.

The paper gives reasons for low energy efficiency typical of the Serbian economy, which is based on outdated and dirty technologies. The comparison of selected economic indicators and indicators of energy efficiency in both Serbia and the European Union points out the benefits of the Kyoto Protocol implementation due to the growth of competitiveness in the global market. Serbia has no obligation to reduce GHG emissions, the authors point to the proposals whose implementation along with the mechanisms of the Protocol can enable Serbia the access to markets that trade GHG emissions and the access to dedicated funds, self-financing or attracting foreign investments to raise energy efficiency, which will be accompanied by adequate economic benefits. A similar principle can be applied in all countries that are not obliged to reduce GHG emissions. The application of different mechanisms aiming to increase energy efficiency in Serbia, could contribute to the increase of GDP annual growth rate from 5% to 7%, which cannot be achieved by any other economic instrument. Energy efficiency, which is actually a question of competitiveness of each economy, can finance itself through the mechanisms of the Kyoto Protocol by selling excess emissions resulting from improved energy efficiency. © 2011 Elsevier Ltd.

Energy demand continues to increase in turn raising concerns about energy supply. In this paper, the author has tried to systematize the role of the energy sector in South Eastern (SE) Europe in the context of the European energy policy process. This should make the energy sector in SE Europe more visible and open to substantial activities and appropriate funding. This is important to assure its full alignment with the European energy policy process, and in so doing, make it less fragile. According to the SE European Energy Community Treaty, parties to the Treaty are obliged to implement reforms in the energy and environmental sector in accordance with the European Union's respective policy. This paper raises awareness of the environmental requirements that have been set, of renewable energy and its implementation, at the same time pointing out that the response in SE Europe has been at a low level. It is believed that this paper could draw attention to the existing problems and could contribute to the establishment of a common integrated energy market in SE Europe and the EU. © 2009 Elsevier Ltd.

Advances in technology have expanded the methods by which users interact with computer-based systems beyond the screen and into physical space. To design these types of innovative interfaces, new design techniques and practices will be needed to understand how users perceive and interact with such multimodal environments. One area where we can look for such novel approaches is the field of interactive media art and design. An interactive art installation called Art Machine: MindCatcher was built to allow users to create audio-visual sentences (artifacts) by moving through a field of sensors that generate circles and sounds that varied depending upon the amount of time spent on the sensor. This research experiment has intention to contribute to the field of collective creativity and participatory design by representing a test-of-concept regarding the viability of interactive media art and design as a method that contributes to the repertoire of techniques and practices for engaging participants in design activities. © Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2015.
