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.

This thesis deals with the structure of the no-wait job-shop problem as well as the derivation of fast approximation algorithms. These algorithms are based on a decomposition approach into a sequencing and a timetabling problem that was initially introduced by Macchiaroli et al. (1999). In the thesis the problems are derived from a mixed integer formulation of the original problem and proved to be NP-hard in the strong sense. After presenting a fast heuristic approach for the timetabling problem, the focus lies on the sequencing problem for which several local search algorithms are presented. The algorithms are tested on a wide variety of benchmark problems for the classical job-shop problem. Among the algorithms, the tabu search approach outperforms all other algorithms that can be found in the literature in objective value as well as computation time.

Stochastic programming offers a way to treat uncertainty in decision problems. In particular, it allows the minimization of risk. We consider mean-risk models involving deviation measures, as for instance the standard deviation and the semideviation, and discuss these risk measures in the framework of stochastic dominance as well as in the framework of coherent risk measures. We derive statements concerning the structure and the stability of the resulting optimization problems whereby we emphasize on models including integrality requirements on some decision variables. Then we propose decomposition algorithms for the mean-risk models under consideration and present numerical results for two stochastic programming applications.
