fischer Befestigungssysteme: Change Management in der Distributionslogistik - eine Fallstudie

Zwischen dem Studiengang Betriebswirtschaft / Einkauf und Logistik und der Unternehmensgruppe fischer besteht seit Jahren eine fruchtbare Zusammenarbeit. Studentische Projekte mit Problemstellungen aus Einkauf und Logistik werden unter Betreuung von Professoren direkt im Unternehmen durchgeführt, und Führungskräfte von fischer kommen als Referenten zu Workshops des Studiengangs an die Hochschule. Die bedeutende Investition in ein automatisches Kommissioniersystem im Global Distribution Center (GDC) der fischerwerke im Jahr 2015 stellte das Management des GDC vor eine besondere Herausforderung, änderte sich doch das Tätigkeitsprofil für einen großen Teil des Kommissionierpersonals. So entstand die Idee, diese Aufgabenstellung als Hintergrund für eine Fallstudie zum Thema "Change Management" zum Einsatz in der Ausbildung sowohl an der Hochschule wie im Unternehmen zu erstellen. Die Umsetzung der Idee erfolgte im Forschungssemester von Prof. Dr.-Ing. Klaus Möller im WS 2015/16. Die Entwicklung der nun vorliegenden Fallstudie parallel in Deutsch und in Englisch wurde in Zusammenarbeit mit Julian Gabel (B.Sc.) und dem Kollegen Prof. Dr.-Ing. Frank Bertagnolli aus dem Bereich Ressourceneffizienzmanagement durchgeführt. Wir danken Matthias Wehle, Eckhard Hagen und Hendrik Schote für die intensiven inhaltlichen Diskussionen und die effiziente Unterstützung bei der Informationsrecherche auf der Unternehmensseite

The Federal Republic in the North-South dialogue: Some longerterm projections

For some time now the Federal Republic of Germany has been the largest exporter in the world, with a slight lead over the USA and some way ahead of Japan and the Soviet Union. It has therefore an important role to play in the North-South dialogue. The increasing mutual dependence of the Federal Republic and the developing countries is described by different scenarios in the following article

Face recognition based on the proximity measure clustering

In this paper problems of featureless face recognition are considered. The recognition is based on clustering the proximity measures between the distributions of brightness clusters cardinality for segmented images. As a proximity measure three types of distances are used in this work: the Euclidean, cosine and Kullback-Leibler distances. Image segmentation and proximity measure clustering are carried out by means of a software model of the recurrent neural network. Results of the experimental studies of the proposed approach are presented

On the Shell Structure of Nuclear Bubbles

We investigate the shell structure of spherical nuclear bubbles in simple phenomenological shell model potentials. The shell correction energies for doubly magic bubbles may be as large as -40 MeV and probably imply a very long lifetime against spontaneous fission. Beta-stability occurs for ratios of the neutron number N to the proton number Z which differ markable from the beta-stability valley of ordinary compact nuclei. The alpha-decay probability is shown to be very small for proton rich bubbles with a moderately large outer radius. Metastable islands of nuclear bubbles are shown to exist for nucleon in the range A=450 - 3000.Comment: 37 pages, latex, 27 figures in the eps format include

Особенности разработки палеозойских отложений Томской области

peer reviewedProton magnetic resonance spectroscopic data ((1)H-MR spectroscopy) of patients with 18q deletion syndrome have not yet been reported. (1)H-MR spectroscopy, performed in an affected 2-year-old girl with markedly delayed neuromotor development and typical supratentorial white-matter disease (WMD), showed an increase of choline and alpha-glutamate concentrations. Eight months later, simultaneously with clinical improvement, alpha-glutamate had normalised whereas choline remained slightly increased. Active demyelination or increased myelin turnover might contribute to the hitherto unexplained WMD of this rare disorder

The deactivation of Zeolite-Y and mordenite during hexane cracking and propene oligomerisation

Bibliography : pages 244-253.The objective of this study was to determine the effect that the type of catalyst and reaction would have on the rate of deactivation, properties of coke and transport properties of the catalyst. HY and HM were chosen because of their different pore structures and acid site distributions. Hexane cracking at 1 atmosphere and high pressure propene oligomerisation provided two different reaction types. The transport properties of the catalysts were compared by measuring adsorption and diffusion using the GC technique with ancillary information obtained from ammonia TPD, mercury porosimetry and BET surface area measurements. It was confirmed that a knowledge of the crystallite size distribution was necessary to predict the adsorption and diffusion of light hydrocarbons in HY and HM. The adsorption constants and heats of sorption were found to,be much greater in HM than in HY, in agreement with the presence of a greater number of strong acid sites detected in HM by ammonia TPD. The diffusivities of the Tight hydrocarbons were too large to measure in HY. In HM only methane diffusion was too fast to measure. Diffusivities decreased and adsorption constant increased with increasing molecular size. HY had greater activity and slower deactivation than HM towards hexane cracking. The reaction as well as coking took place in the micro-pores. The graphitic coke content of HY was much greater than in HM. The introduction of the macro-pore adsorption term was necessary to predict diffusion in coked samples, emphasizing the severity of the diffusional resistance. While hydrocarbon diffusivities decreased after cracking, adsorption constants were found to increase in the presence of graphitic coke in J-IY. In HM the deactivation took place primarily by pore blockage, with strong acid sites being preferentially removed. Both diffusivities and adsorption constants decreased in the presence of coke in HM. In HY and HM deactivated by oligomerisation, macro-pore adsorption had to be taken into account, again emphasizing the severe diffusional resistance. Reaction as well as graphitic coke occurred predominantly in the micro-pores in HY. High boiling point hydrocarbons were able to migrate into the mesopores where they closed the mouths of the micro-pores in HY. Strongly adsorbed high boiling point hydrocarbons which deactivated the catalyst presented far less diffusional resistance in HY than the equivalent mass of graphitic coke. These high boiling point hydrocarbons also markedly lowered the adsorption constants. Graphitic coke was responsible for the modification of the catalyst selectivity. Temperature runaway in HY caused severe coking and hence deactivation. The inactivity of HM below 200°C was caused by strong adsorption and high diffusional resistance of reactant and product. Pore blockage was the dominant deactivation mechanism in HM, while in HY it was partial pore blockage by graphitic coke and pore mouth closure by high boiling point hydrocarbons. It was possible to restore the activity of HY for oligomerisation by flushing the high boiling point hydrocarbons in flowing nitrogen
