  I suppose that there is a relation between the success of EU-funded projects and the effectiveness of project management teams which implement them. To examine the accuracy of the assumption and the nature of the relationship I needed a measurement method that was suitable for measuring the effectiveness of project management teams implementing EU funded projects in a given construction. Since Data Envelopment Analysis (DEA) has already been used to measure the efficiency of decision making units in other areas, it seems suitable for measuring project management effectiveness and indirectly measuring project efficiency.

  A significant proportion of the aboveground green and dry weight of the plant is constituted by foliage. The canopy is an important factor of plant growth. On the one hand, the canopy absorbs solar energy, which is necessary for photosynthesis; on the other hand, it accumulates the nutrients absorbed by the roots, and most of the water-loss occurs through the foliage. The determination of the full canopy is not an easy target. In our research, we developed a measurement method to determine the leaf area. With the parameters of the examined tree (leaf length and maximum width) and the data of the ADC AM 100 leaf area scanner, we determined the k-value, with which we can easily and fast evaluate the leaf surface. Furthermore, we defined from the water balance of compensation lysimeters the cumulative transpiration of fruit trees and the efficiency of water use of trees. From the examined trees were made a 3D depiction, which show the shape, branching and the location of trees.

  In Hungary the renewable energy utilization is planned to achieve 13% by 2020. Biogas production is one of the fields with the largest energy potential. Achieving high efficiency during continuous production despite the mixed and variable composition of input materials is the most common problem which the newly built biogas plants using agricultural raw materials have to deal with. The first experimental reactors at the Department of Water and Environmental Management were built 12 years ago. Control and automation of the four separated bioreactors were executed with ADVANTECH GENIE 3.0 software which granted pre-programmed measurement and points of intervention for pH, temperature, CH4, CO2, H2S, and NH3. The system became out-of-data, therefore in 2010 it has been redesigned and tested. The system is controlled by Compair Proview SCADA (Supervisory Control and Data Acquisition) software running on Linux platforms. The Fusarium infection caused serious yield-losses in cereal production in 2010. In the case of cereal products, which non-utilizable as forage seems an optimal solution is utilizing as biogas raw material. The raw material was based on the Fusarium infected maize. In the recent publication infotechnological and technological experiences of the pilot test period are evaluated as well as direction of future development is defined.

  Projects funded by the European Union contribute significantly to the socio-economic development of Hungary, its increasing competitiveness, thereby the local people's general level of satisfaction, their ”happiness and prosperity”. Successful spending from the Union's funds, successful project implementation directly impacts all actors in the Hungarian economy and society. Therefore, to examine the factors that support or jeopardize the implementation of the projects is a priority at EU and national levels. My research and doctoral dissertation aims to develop a methodology to assess the management efficiency of projects supported by the European Union, implemented in Hungary taking into account all measurable factors (technical and special expertise) and the "suspected" factor (EU thinking learning).

  I intend to draw up guidelines for future EU funded project management teams to realize projects successfully for the benefit of Hungary.

  A significant proportion of the aboveground green and dry weight of the plant constitutes the foliage. The canopy is an important factor
  of plant growth. On one hand the canopy absorbs the solar energy, which is necessary for the photosynthesis, on the other hand accumulates
  the absorbed nutrients by the roots, and the most of the water-loss happens through the foliages. The determination of the full canopy is not
  an easy target. In our research we developed a measurement method to determine the leaf area. With the parameters of the examined tree
  (leaf length and maximum width) and the data of ADC AM 100 leaf area scanner we determined the k-value, with which we can easily and
  fast evaluate the leaf surface. Furthermore we defined from the water balance of compensation lysimeters the cumulative transpiration of
  fruit trees and the efficiency of water use of trees.
