  1. Master Data Life Cycle - Stammdatenprozesse in SAP am Beispiel Materialstamm

    NASA Astrophysics Data System (ADS)

    Hildebrand, Knut

    Stammdaten (Geschäftsobjekte) sind der Datenbestand, auf dem Geschäftsprozesse aufbauen, und der über einen längeren Zeitraum erhalten bleibt, z.B. Kunden oder Artikel. Daher ist ihre Datenqualität sehr wichtig! Stammdaten ändern sich nicht während einer betrieblichen Transaktion - der Buchung eines Geschäftsvorfalls -, aber sie steuern ihn und fließen in die Belege (Bewegungsdaten) ein, die diesen Prozessschritt dokumentieren. Stammdaten ändern sich jedoch sehr wohl im Laufe ihres Lebens, da sich die einzelnen Attributswerte weiterentwickeln können. Beispielsweise die Anschrift oder Rechtsform eines Lieferanten oder die Dispositions-Parameter eines Materials.

    , rather than saturation of extracted compounds in the solvent when CO2 is stationary. Total extraction yields seem to be low compared to the OM present in the reservoir rock, but yields still have to be extrapolated to the large volumes of reservoir rock that are in contact with supercritical CO2 at the test site. In the future, our lab results may be combined with models to determine how much of the mobilised organic acids and non organic material will occupy the entire reservoir (pore space) or could be used by organisms and induce growth. Additionally, the rock samples were analysed after the extraction with supercritical CO2, using a variety of organic and inorganic geochemical techniques. Thus, changes in the composition of the rocks were also observed. Here, amongst others, scanning electron microscopy was done and indicated corrosion effects on mineral surfaces due to exposure to supercritical CO2. References Hawthorne, S.B.

    Meilensteine der modernen Produktion mit Lean Production, Total Quality Management, Six Sigma, Supply Chain Management, Lean Management und Lean Enterprise können zu effizienteren Abläufen führen. In der betrieblichen Praxis existiert jedoch eine Vielzahl von Zielkonflikten basierend auf Richtlinien von Material Requirements Planning- (MRP), Controlling- und anderen Systemen. Nur wenige Spezialisten in größeren Unternehmen sind im Stande, die Komplexität über die Grenzen eines Fachgebiets hinaus im Detail zu verstehen. Fachübergreifendes Verständnis scheitert an der Komplexität der Gesamtproblematik. Entscheidungen verschiedenster Fachbereiche begrenzen die maximal erreichbare Effizienz des Materialflusses. Logistik und Materialfluss werden daher in vielen Unternehmen als unabdingbare Kernkompetenz verstanden. Um eine schlanke Produktion, einen optimalen Materialfluss und somit minimale Produktkosten zu erreichen, sind folglich vielfältige andere Fachthemen als Vorraussetzungen zu beherrschen. Erst dann ist es in der Produktionslogistik möglich, im Vergleich zu einem Top-Benchmark erfolgreich zu sein. Um im täglichen Konkurrenzkampf die Nase auch morgen noch vorne zu haben" ist es nötig, über den Preis hinaus auch noch völlig andere Problemstellungen zu beherrschen.

    To expand the passive safety of automobiles protecting traffic participants technological innovations were done in the last decades. Objective of our retrospective analysis was to examine if these technical modifications led to a clearly changed pattern of injuries of pedestrians whose death was caused by the accidents. Another reduction concerns the exclusion of injured car passengers--only pedestrians walking or standing at the moment of collision were included. We selected time intervals 1975-1985 and 1991-2004 (=years of construction of the involved passenger cars). The cars were classified depending on their frontal construction in types as presented by Schindler et al. [Schindler V, Kühn M, Weber S, Siegler H, Heinrich T. Verletzungsmechanismen und Wirkabschätzungen der Fahrzegfrontgestaltung bei Pkw-Fussgänger-Kollisionen. Abschlussbericht im Auftrag der Deutschen Versicherungswirtschaft e.V. TU-Berlin Fachgebiet Kraftfahrzeuge (GDV) 2004:36-40]. In both periods more than 90% of all cars were from the usual types small/medium/large class. Hundred and thirty-four autopsy records of such cases from Department of Forensic Medicine (Charité Berlin) data were analysed. The data included technical information of the accidents and vehicles and the external and internal injuries of the victims. The comparison of the two periods showed a decrease of serious head injuries and femoral fractures but an increase of chest-, abdominal and pelvic injuries. This situation could be explained by an increased occurrence of soft-face-constructions and changed front design of modern passenger cars, resulting in a favourable effects concerning head impact to the car during accident. Otherwise the same kinetic energy was transferred to the (complete) victim - but because of a displacement of main focus of impact the pattern of injuries modified (went distally).

    The uncertainty in precipitation observations largely influences the performance of rainfall-runoff models. In this study we present first results of a sensitivity analysis that should help to improve our understanding on the impacts on hydrological model simulations of different rainfall datasets that are characterized by variable spatial resolutions. The study area is the well-equipped/observed meso-scale catchment of the Sauer River in the Grand Duchy of Luxembourg. Data used are observations from 15 rain gauges, radar rainfall estimations from the German Weather Service (RADOLAN dataset (Bartels, 2004)) and the Royal Meteorological Institute of Belgium (Wideumont C-band weather radar), as well as the outputs of the regional atmospheric model WRF. In a first step we assess the suitability of the data as forcing datasets specifically for hydrological modelling by analysing and comparing their properties with regard to precipitation climatology, extreme events and rainfall patterns. The radar and WRF grid data are combined with raingauge data by applying the Sinclair-Pegram (Sinclair and Pegram, 2005) radar-gauge merging method. The aim of this analysis is to produce suitable data sets, which can be used in a future step to force various hydrological models based on the FLEX model (Fenicia et al, 2007), a lumped conceptual rainfall-runoff model, with different spatial model structures.

    migration in the subsurface has been conducted, as well as stress modelling to estimate frac dimension magnitudes and the potential frequency of induced seismity. The results of these simulations reveal that the probabiltiy of impacts on shallow groundwater by the upward migration of fracking fluids from a deep shale formation through the geological underground in the North German basin is small.

    levellings (especially the first by Lentz in 1855), the correction has been questioned several times in the recent years (e.g. Jensen et al. 1992; Wahl et al. 2011; Jensen et al. 2011). Here, we choose a different approach and compare the record of Cuxhaven to 18 nearby stations from the North and Baltic Sea region. Based on visual inspections, linear regression and correlation analyses before and after applying the correction we find that the Cuxhaven record compares best to the other sites if the correction is not applied. Therefore, we conclude that the correction remains still questionable and should not be applied to the raw data.
