  abstract  = {In dieser Bachelorarbeit werden die Bedeutung und die Gebrauchsweisen des Vergangenheitstempus Perfekt in der deutschen und spanischen Sprache kontrastiv untersucht. Aufgrund des Zusammenwirkens der funktional-semantischen Kategorien Temporalit{\"a}t, Aspektualit{\"a}t und Modalit{\"a}t wird der Perfektgebrauch hinsichtlich dieser Kategorien analysiert. Es wird angenommen, dass sich das Perfekt im Spanischen und Deutschen nicht nur in Bezug auf seine temporalen und aspektuellen Werte, sondern auch hinsichtlich seiner modal-evidentiellen Werte und Ausdrucksweisen unterscheidet. Ziel dieses Beitrags ist es, die spezifischen temporalen und aspektuellen Bedeutungen dieses Vergangenheitstempus in der jeweiligen Sprache herauszustellen, kontrastiv zu betrachten und zu zeigen, inwiefern Perfektformen als Evidentialit{\"a}tsmarker fungieren k{\"o}nnen. Der modal-evidentiellen Bedeutung des Perfekts kommt in dieser Arbeit eine zentrale Rolle zu, da insbesondere hinsichtlich der deutschen Perfekt-Konstruktionen noch wenige Forschungsans{\"a}tze vorliegen. Die modalen und evidentiellen Bedeutungen des Perfekts werden in beiden Sprachen in der Schriftsprache unter Einbezug der Erkenntnisse der RAE (2009), Wachtmeister-Berm{\´u}dez (2005) und Diewald (2011) diskutiert und anhand von Beispielen aus spanischen und deutschen Pressetexten des CREA sowie der Zeit Online und S{\"u}ddeutsche Zeitung belegt. Als Ergebnis dieser Untersuchung l{\"a}sst sich feststellen, dass das Perfekt in beiden Sprachen als Evidentialit{\"a}tsmarker dienen und verschiedene Arten von Evidenz markieren kann. Die Relevanz der kontrastiven Betrachtung kommt in zwei signifikanten Forschungsbereichen zum Tragen: zum Einen bei der {\"U}bersetzung, da die temporalen, aspektuellen und modal-evidentiellen Werte des Perfekts in der jeweiligen Sprache beachtet werden m{\"u}ssen und zum Anderen in der Fremdsprachendidaktik, da das Perfekt verschiedene Stellenwerte in den einzelnen Verbalsystemen einnimmt.},

  abstract  = {Die Arbeit befasst sich zun{\"a}chst mit der Analyse und Einordnung des Begriffs der Daseinsvorsorge und deren Erbringung durch den Staat. Schwerpunkt der Betrachtung bildet dabei die Energieversorgung als klassische Aufgabe staatlicher Daseinsvorsorge. Weiterhin wird der durch die Liberalisierung der Energieversorgung im Jahr 1998 eingeleitete Wandel von sog. nat{\"u}rlichen Monopolen, hin zu einem wettbewerblichen System betrachtet. Dabei wird aufgezeigt, dass sich durch die Einf{\"u}hrung des Wettbewerbs weder die damit erhofften Kostenreduzierungen, noch das von Kritikern bef{\"u}rchtete Sterben der kommunalen Energieversorger bewahrheitet haben. Statt einer freien Preisbildung im Wettbewerb ist es zu einer faktischen Verlagerung der fr{\"u}her staatlich festgesetzten Energiepreisgenehmigung auf die Gerichte gekommen, die hierf{\"u}r jedoch nicht ausgelegt sind. Kommunale Stadtwerke haben sich in der wettbewerblichen Energieversorgung dagegen so gut behauptet, dass seit einiger Zeit ein Trend zur Rekommunalisierung von Energieversorgung auf kommunaler Ebene zu verzeichnen ist. Diesem offensichtlichen Wunsch nach einer gesteigerten Einflussnahme der Gemeinden auf die {\"o}rtliche Energieversorgung l{\"a}uft der aktuelle Rechtsrahmen der energierechtlichen Konzessionsvergabe in Gestalt des \S 46 EnWG und seiner Auslegung durch die Rechtsprechung der Zivilgerichte zuwider. Die Arbeit zeigt auf, dass von Beginn der Liberalisierung der kommunale Einfluss auf die {\"o}rtliche Konzessionsvergabe schrittweise und stetig beschnitten wurde, so dass gegenw{\"a}rtig ein Zustand der Aush{\"o}hlung erreicht ist, der als unzul{\"a}ssiger Eingriff in den gesch{\"u}tzten Kernbereich der kommunalen Selbstverwaltungsgarantie i.S.d. Art. 28 II GG anzusehen ist.},

  abstract  = {Previous studies suggested that electric and/or magnetic field fluctuations observed in the nighttime topside ionosphere at midlatitudes generally originate from quiet time nocturnal medium-scale traveling ionospheric disturbances (MSTIDs). However, decisive evidences for the connection between the two have been missing. In this study we make use of the multispacecraft observations of midlatitude magnetic fluctuations (MMFs) in the nighttime topside ionosphere by the Swarm constellation. The analysis results show that the area hosting MMFs is elongated in the NW-SE (NE-SW) direction in the Northern (Southern) Hemisphere. The elongation direction and the magnetic field polarization support that the area hosting MMFs is nearly field aligned. All these properties of MMFs suggest that they have close relationship with MSTIDs. Expectation values of root-mean-square field-aligned currents associated with MMFs are up to about 4nA/m(2). MMF coherency significantly drops for longitudinal distances of 1 degrees.},

  abstract  = {Disjunctive Answer Set Programming is a powerful declarative programming paradigm with complexity beyond NP. Identifying classes of programs for which the consistency problem is in NP is of interest from the theoretical standpoint and can potentially lead to improvements in the design of answer set programming solvers. One of such classes consists of dual-normal programs, where the number of positive body atoms in proper rules is at most one. Unlike other classes of programs, dual-normal programs have received little attention so far. In this paper we study this class. We relate dual-normal programs to propositional theories and to normal programs by presenting several inter-translations. With the translation from dual-normal to normal programs at hand, we introduce the novel class of body-cycle free programs, which are in many respects dual to head-cycle free programs. We establish the expressive power of dual-normal programs in terms of SE- and UE-models, and compare them to normal programs. We also discuss the complexity of deciding whether dual-normal programs are strongly and uniformly equivalent.},

  abstract  = {Optical frequency combs (OFC) constitute an array of phase-correlated equidistant spectral lines with nearly equal intensities over a broad spectral range. The adaptations of combs generated in mode-locked lasers proved to be highly efficient for the calibration of high-resolution (resolving power > 50000) astronomical spectrographs. The observation of different galaxy structures or the studies of the Milky Way are done using instruments in the low- and medium resolution range. To such instruments belong, for instance, the Multi Unit Spectroscopic Explorer (MUSE) being developed for the Very Large Telescope (VLT) of the European Southern Observatory (ESO) and the 4-metre Multi-Object Spectroscopic Telescope (4MOST) being in development for the ESO VISTA 4.1 m Telescope. The existing adaptations of OFC from mode-locked lasers are not resolvable by these instruments. Within this work, a fibre-based approach for generation of OFC specifically in the low- and medium resolution range is studied numerically. This approach consists of three optical fibres that are fed by two equally intense continuous-wave (CW) lasers. The first fibre is a conventional single-mode fibre, the second one is a suitably pumped amplifying Erbium-doped fibre with anomalous dispersion, and the third one is a low-dispersion highly nonlinear optical fibre. The evolution of a frequency comb in this system is governed by the following processes: as the two initial CW-laser waves with different frequencies propagate through the first fibre, they generate an initial comb via a cascade of four-wave mixing processes. The frequency components of the comb are phase-correlated with the original laser lines and have a frequency spacing that is equal to the initial laser frequency separation (LFS), i.e. the difference in the laser frequencies. In the time domain, a train of pre-compressed pulses with widths of a few pico-seconds arises out of the initial bichromatic deeply-modulated cosine-wave. These pulses undergo strong compression in the subsequent amplifying Erbium-doped fibre: sub-100 fs pulses with broad OFC spectra are formed. In the following low-dispersion highly nonlinear fibre, the OFC experience a further broadening and the intensity of the comb lines are fairly equalised. This approach was mathematically modelled by means of a Generalised Nonlinear Schr{\"o}dinger Equation (GNLS) that contains terms describing the nonlinear optical Kerr effect, the delayed Raman response, the pulse self-steepening, and the linear optical losses as well as the wavelength-dependent Erbium gain profile for the second fibre. The initial condition equation being a deeply-modulated cosine-wave mimics the radiation of the two initial CW lasers. The numerical studies are performed with the help of Matlab scripts that were specifically developed for the integration of the GNLS and the initial condition according to the proposed approach for the OFC generation. The scripts are based on the Fourth-Order Runge-Kutta in the Interaction Picture Method (RK4IP) in combination with the local error method. This work includes the studies and results on the length optimisation of the first and the second fibre depending on different values of the group-velocity dispersion of the first fibre. Such length optimisation studies are necessary because the OFC have the biggest possible broadband and exhibit a low level of noise exactly at the optimum lengths. Further, the optical pulse build-up in the first and the second fibre was studied by means of the numerical technique called Soliton Radiation Beat Analysis (SRBA). It was shown that a common soliton crystal state is formed in the first fibre for low laser input powers. The soliton crystal continuously dissolves into separated optical solitons as the input power increases. The pulse formation in the second fibre is critically dependent on the features of the pulses formed in the first fibre. I showed that, for low input powers, an adiabatic soliton compression delivering low-noise OFC occurs in the second fibre. At high input powers, the pulses in the first fibre have more complicated structures which leads to the pulse break-up in the second fibre with a subsequent degradation of the OFC noise performance. The pulse intensity noise studies that were performed within the framework of this thesis allow making statements about the noise performance of an OFC. They showed that the intensity noise of the whole system decreases with the increasing value of LFS.},
