This paper concerns the optimization and coordination of the conventional FACTS (Flexible AC Transmission Systems) damping controllers in multi-machine power system. Firstly, the parameters ofFACTS controller are optimized. Then, a hybrid fuzzy logic controller for the coordination of FACTS controllers is presented. This coordination method is well suitable to series connected FACTS devices like UPFC, TCSC etc. in damping multi-modal oscillations in multi-machine power systems. Digital simulations of a multi-machine power system subjected to a wide variety of disturbances and different structures validate the efficiency of the new approach.

Competitive markets play a key role in modern industrial In many European countries, politicians set the stage for an open electricity market to facilitate competition with full access to grids. This has led to changes in load-flow patterns in transmission networks. The grid access is accompanied by large power transits even over long distances and unpredictable short-term changes of system conditions.

This paper deals with suitable approaches for fast assessment of oscillatory stability of large interconnected power systems within power system operation. Beside voltage stability and transient stability, oscillatory stability has to be assessed, too. It can be shown, that parallel eigenvalue computation using a parallel variant of Arnoldi method can reduce the time necessary for eigenvalue computation of large power systems.

This paper introduces several feature extraction and selection techniques.Previous studies showed good results when neural networks are applied to the small-signal stability assessment. However the use of reduction techniques can decrease the number of features and thus the number of quantities, which need to be observed, measured and transmitted, respectively.

The thesis in social science concerns problems of guadianship for adults, which is in a process of getting a liberal profession. The first part treats with the classification of guardianship from a theoretical point of view. Next, an empirical exploration is presented, that contains aspects of the actual professional profile of guadians by focussing the professions of social work. The dissertation closes with an résumé of results and proposals of further research.

This doctoral thesis examines the role and influence of civil society organisations in European multilevel governance structures. Therefore the policy field of sustainability is chosen to analyse how and if civil society organisations can take part in European decision making processes. The case study focuses on the participation process for the organised civil society during the negotiations for the European Constitution by analysing the conventions forum as a new and electronically based participation-channel. Background of the examination are the reforms of the European Commission under the presidency of Romano Prodi, in office from 1999 to 2004; with a focus on the European Governance Reform introduced basically by the Commissions White Paper on Governance in the year 2001. The theoretical background of the study is the theory of ecological communication by the German sociologist Niklas Luhmann to reflect the problems and chances for societal communication processes in functional differentiated societies. The specific role organisations can play to transform and communicate relevant information and alternative knowledge requests innovative governance structures which are able to improve the quality of societal communication and which are necessary to find generally accepted solutions for problems with supra-national character. The specific role of civil society organisations for societal- and systemic integration is underlined by Montesquieus theory of secondary powers (pouvoirs intermédiaires) and leads to a differentiated understanding of NGOs in processes of political communication.

This thesis deals with the nickelspecies-analysis in cytosol of human intestinal tissue. The aim was, to find the differences in nickelspecies between the cytosol of malignant and normal tissue of the same patient with CE/ICP-MS resp. SEC/ICP-MS coupling. The result was, that the area ratio of two nickelspecies in the cytosol of malignant tissue are significant higher than in the cytosol of normal tissue. Maybe the two nickelspecies can be an oncogenproduct.

During the irradiation of 1-acetylnaphthaline in the presence of c,d-substituted olefines with a cyclic amine as a donor different products were generated. The reaction pathways were monitored by NMR-spectroscopy and it was proved that the main products were generated by a Photo-Diels-Alder-reaction. The c,d-olefines are added head-to-tail with the donor substituent in endo-position to the remaining aromatic system. Their structures could unambiguously be proven by single crystal x-ray structure analysis. Furthermore their thermal and photochemical properties were investigated: the activation enthalpies and activation entropies for their thermal decompositions were investigated and during their irradiation in solution with light of 254 nm a Di-<font face="Symbol">p</font>-methane-rearrangement could be observed.
