    Synchronization in the presence of distributed delays

    Full text link
    We study systems of identical coupled oscillators introducing a distribution of delay times in the coupling. For arbitrary network topologies, we show that the frequency and stability of the fully synchronized states depend only on the mean of the delay distribution. However, synchronization dynamics is sensitive to the shape of the distribution. In the presence of coupling delays, the synchronization rate can be maximal for a specific value of the coupling strength.Comment: 6 pages, 3 figure

    SURVIVING POSSIBLE? A QUALITATIVE ANALYSIS OF THE CURRENT TRANSFORMATION PROCESSES IN THE GERMAN AUTOMOTIVE SUPPLIER INDUSTRY, DUE TO AUTONOMOUS AND ELECTRIC VEHICLES

    The importance of the automotive industry for Germany’s economy and employment is significant: 24% of total revenue for manufacturing and processing goods is gained by the automotive industry in Germany with over 800,000 employees. As the supply side contributes 3/4 to the value chain, the research focuses on German automotive suppliers and how they perceive the shift from combustion engines to electric engines and to fully autonomous vehicles. For the explorative study, a qualitative content analysis based on expert interviews was used. 15 top and high-level managers from 14 German automotive suppliers were personally interviewed. The analysis has proven that most suppliers are significantly affected through these transformations. Only three suppliers evaluate the changes mainly as growth drivers for their business, while the rest faces large challenges and great threats from the industry developments.The importance of the automotive industry for Germany’s economy and employment is significant: 24% of total revenue for manufacturing and processing goods is gained by the automotive industry in Germany with over 800,000 employees.

    Synchronization Dynamics in the Presence of Coupling Delays and Phase Shifts

    In systems of coupled oscillators, the effects of complex signaling can be captured by time delays and phase shifts. Here, we show how time delays and phase shifts lead to different oscillator dynamics and how synchronization rates can be regulated by substituting time delays by phase shifts at a constant collective frequency. For spatially extended systems with time delays, we show that the fastest synchronization can occur for intermediate wavelengths, giving rise to novel synchronization scenarios.This work was supported by spanish Ministry of Economy and Competitiveness (MINECO) through Grant PHYSDEV (No. FIS2012-32349) and from CSIC through the Junta para la Ampliación de Estudios program (JAEDOC014, 2010 call) cofunded by the European Social FundPublicad

    Kooperatives Informationsmanagement: Strukturen und Kulturen für die Zusammenarbeit zwischen DV-Abteilung und Fachabteilungen

    Get PDF
    Kooperation ist weder Selbstzweck noch Selbstverständlichkeit. Kooperation im Informationsmanagement soll DV-lnitiativen besser vorantreiben. Im Zentrum der Kooperationslandschaft stehen die DV-Abteilung und die Fachabteilungen. Es gilt, deren Stärken organisatorisch so zu kombinieren, daß das Kooperationsziel erreicht wird. Ein strategiegerechtes Informationsmanagement bewegt sich im Spannungsfeld zwischen Integrations- und Flexibilitätsanforderungen. Eine Übersicht über mögliche Kooperationsformen gibt Denkanstöße für die Gestaltung geeigneter Kooperationsformen innerhalb dieses Spannungsfelds. Sie mündet in einer heuristischen Aussage für die Konstruktion kontextgerechter Kooperationsmodelle. Die nachfolgenden Ausführungen verdeutlichen, daß die Organisationsarbeit ein kooperatives Informationsmanagement durch Service-Leistungen unterstützen muß

    Seit langer Zeit ist man sich in der DV-Gemeinde einig, daß die Performance von Informationssystemen nicht primär von Drähten und Bits abhängt. Software und Service haben der Hardware als DV-Faktor Nr.1 den Rang abgelaufen. Die Fokussierung auf Soft-Factors ist im Informationsmanagement jedoch noch nicht konsequent genug vorangetrieben worden
