Bosnia & Herzegovina state has good potentials for generation of electric power. It applies, first of all, to its water and coal potentials. In addition to this, Bosnia & Herzegovina has good potentials of certain renewable energy sources, namely: wind, sun, water flows, and biomass. Observation and measurement of wind characteristics in Bosnia & Herzegovina have been performed for over 120 years now. However, the first measurements with adequate equipment and technology aimed at determining of the wind energy potential, started in 2002. Research is still incomplete and limited by complex terrain, the wind type "Bora", as well as by non-existence of necessary strategic documents and regulations on renewables. Based on this research, several wind farms have been already planned, with an installed power of about 200 MW, and with a high coefficient of energy efficiency. This paper provides a review of localities from the wind characteristics research performed in the area of Bosnia & Herzegovina in the period 2002-2008. Additionally, it gives a brief reference to the complexity of wind potential research under complex conditions of terrain and wind type in Bosnia & Herzegovina, giving in this way a contribution to a more realistic estimate of economically feasible potential of Bosnia and Herzegovina, which will consequently help creation of needed strategic documents.

Intense and stressful group decision-making has become a daily activity in the modern business environments which caused greater interest in systems that allow simulation of group decision-making with agents as human representatives (surrogates). Development of representative agents is significantly enhanced through use of methods that allow mapping of some of the most important human traits in the world of agents. These traits are emotions, personality and mood which gain importance by their direct effect on the process of individual and therefore group decision-making. In order to provide more stable and efficient group decision-making, this chapter presents the research results of applying concepts of experience and patience to the emotional agents in eLearning environment. Concept of experience is implemented by using Reinforcement learning technique called Q-learning in combination with Self-organizing map, while concept of patience is implemented by introducing a Self-regulation coefficient. © 2014 Springer-Verlag Berlin Heidelberg.

The behavior of the plates with a surface notch under tensile external loading is experimentally and numerically analyzed. The specimens were made of micro-alloyed steel NIOMOL 490K, welded by MAG (CO2) welding method. Surface notches were machined by the spark erosion method in the weld metal and heat affected zone. A finite element analysis of the specimens subjected to the tensile external loading is performed, with a simplified treatment of the heat affected zone mechanical properties. Obtained results are compared with the results of the experimental investigation, and a satisfactory agreement for the specimens containing the weld metal notch is observed. However, results for the specimen containing a notch in the heat affected zone require further investigation, including the analysis of the effects of micro structural heterogeneity. © 2010 Elsevier Ltd.

Intense and usually stressful group decision-making has become a daily activity in the modern business environments which caused the emergence of interest in systems that allow simulation of group decision-making with agents as human representatives (surrogates). Development of representative agents is significantly enhanced through the use of methods that allow mapping of some of the most important human traits in the world of agents. These traits are emotions, personality and mood which gain importance by their direct effect on the process of individual and group decision-making. This paper presents the research results of applying the concept of patience to the emotional agents which should provide more stable and efficient group decision-making. © Springer International Publishing Switzerland 2013.

Ensuring privacy in modern information systems is of primary importance for the users of these environments. Use and trust of users certainly depends on the degree of privacy. Solution for the above mentioned problems can be found in application of the ,Hippocratic Databases - HDB concept". The idea is inspired by the basic principles of Hippocratic Oath to be applied on the databases in order to provide data privacy and confidentiality. Implementation and advantages of this concept have been researched for the needs of business intelligence systems and health information systems, but not of eLearning systems, until now. We have created a prototype model of e-learning environment that fully implements the principles of the HDB database. In order to prove the usability and viability of the model, we compared the performance of the production eLearning system with prototype model. The results of these studies are found in this research paper. Copyright 2012 ACM.
