Master's Thesis from the year 2011 in the subject Business economics - Business Management, Corporate Governance, grade: C, Henley Business School University of Reading, course: Strategie / Marketing, language: English, abstract: The focus of this thesis is on the mixed industry, namely the German general aviation industry, especially on its NPOs (Clubs) and what drives their strategic approaches. The research question was to investigate potential strategic growth options for NPOs in the German general aviation industry, the factors that influence the selection of a specific growth strategy and the higher success rate among the growth strategies. This thesis derived the three objectives: a.The favour of NPOs for a certain strategy/strategic direction, b.the impact of specific growth strategies on NPO performance, and c.the impact of macro and micro environmental and internal factors on the NPOs chosen growth strategy. The content regarded both macro and micro environmental factors and how they are perceived by the NPOs for the German general aviation industry, the growth strategies and generic strategies they follow as well as the market performance they achieve.[...]

The infrared spectral region between wavelengths of 2 and 6 µm is of great importance in molecular physics. Molecules with an X-H bond (X being carbon, nitrogen or oxygen) exhibit strong vibrational transitions there, but also linear carbon clusters Cn (n=2,3,¿). Many combination bands and overtones of low-energy vibrational modes also occur in this spectral range. Analyses of these spectral features allow ¿ if highly resolved ¿ for example the prediction of pure rotational transitions in the sub-mm wavelength regime, or help understanding the internal dynamics of the molecule.To provide radiation sources with extremely large frequency coverage, two optical parametric oscillator (OPO) systems in the wavelength regions from 2.5 to 4.1 µm and from 4.7 to 5.4 µm have been set up and characterized in this thesis. The OPO system around 5 µm wavelength is the only one in this spectral region used in high-resolution spectroscopy up to now. Both of the OPO systems have been shown to be ideal tools for spectroscopic studies delivering highly accurate transition frequencies of transient molecules, using the following example cases:The rovibrational spectrum of the fundamental cation CH2D+ around 3.2 µm wavelength has been measured with unprecedented spectral resolution and frequency accuracy. The combination of the OPO as radiation source with a cold ion trap to produce and store the ions has been proven to have a high predictive power for pure rotational transition frequencies of CH2D+. Located at around 100 to 200 GHz, these are of great importance in astrophysics.The V3 fundamental vibration of Si2C3 around 5.1 µm wavelength has been measured using the OPO and a newly built jet spectrometer for the production of transient molecules. Molecular parameters have been determined with high precision. An associated hot band originating from the V7 vibrational bending mode has been resolved and analyzed for the first time.The pure carbon clusters C3 and C7 have also been examined. For the first time, a combination band of C3 and an associated hot band were detected around 3.0 µm wavelength in the gas phase. Their analyses yield valuable information about the potential energy surface of C3. Analysis of the V5 mode of C7 delivered further proof of its rigidity, which was put into question by earlier works. Last but not least, a previously unknown associated hot band of C7 has been detected and analyzed.

Diplomarbeit aus dem Jahr 2002 im Fachbereich BWL - Allgemeines, Note: 1,3, Hochschule für angewandte Wissenschaften Kempten (Kompetenzzentrum für Unternehmensentwicklung und -beratung), Sprache: Deutsch, Abstract: 1. Einführung in die Thematik1.1 EinleitungMonatelanges Programmieren und Customizing stehen vor der Einführung jeder neuen Industrie-Software. Genaue Anpassungen der Software an die Geschäftsprozesse des Unternehmens und eventuelle Integrationen anderer verwendeter Software ist erforderlich. Der Ressourcenaufwand und die damit verbundenen Investitionen sind enorm hoch; für manche Firmen schon zu hoch.Im Vordergrund der Entscheidung über Neueinführung oder Aktualisierung einer Software stehen primär finanzielle Aspekte. Durch Standardisierung und Optimierung der Bearbeitungsprozesse wird seitens der Unternehmensführung eine hohe Kostendegression vor allem in Folge von Prozessoptimierungen erwartet. Wie kann jedoch die banale Frage nach der Rechtfertigung einer solch großen Investition beantwortetwerden?[...]
