Flughafen Sheremetyevo,Moskau – Planung und Fertigung der Stahldächer und Brücke

Im Zuge einer deutlichen Erweiterung der Fluggastkapazitäten und Modernisierung ist in Moskau das dritte Terminal am Flughafen Sheremetyevo entstanden (Bild 1). Unter der Leitung der Arnold AG übernahm das Büro B+G Ingenieure Bollinger und Grohmann GmbH (B+G) die Planung mehrerer Vordächer und einer Fußgängerbrücke zwischen Parkhaus und Terminal. In der weiteren Entstehung wurden die Firmen Müller Offenburg GmbH & Co. KG (MOG), Heinrich Lamparter Stahlbau GmbH & Co. KG (StaLA) und Radabau GmbH für die Fertigung verpflichtet. Der folgende Beitrag befasst sich mit den Besonderheiten der Planung sowie der Fertigung der einzelnen Bauteile in diesem speziellen Projekt. Sheremetyevo Airport, Moscow, Russia – Structural design and fabrication of steel roofing and bridge. The new Terminal 3 was built as part of the significant expansion and modernization to increase passenger capacities at Sheremetyevo Airport in Moscow (Figure 1). Bollinger + Grohmann Ingenieure carried out the structural design for various canopies and a footbridge between parking garage and terminal building under the supervision of the Arnold AG. In the later stage of the project Müller Offenburg GmbH & Co. KG (MOG), Heinrich Lamparter Stahlbau GmbH & Co. KG (StaLA) and the Radabau GmbH were assigned the manufacturing contract. The following article deals with the peculiarities during the design stage and fabrication of individual structural elements of this particular project.     

Neubau einer einspurigen Straßenbrücke über den Neckar in der Gemeinde Zwingenberg

Mit der Neckarbrücke baut Zwingenberg seine Infrastruktur aus und stärkt den Tourismus in der Region. Der Bau der feingliedrigen Neckarbrücke anstelle des unsicheren, unwirtschaftlichen, zeitlich durch Nachtfahrverbot und hochwasserbedingt stark eingeschränkten Fährbetriebs gewährleistet der Gemeinde Zwingenberg zukünftig einen sicheren Zugang zum linken Neckarufer. Die zweihüftige Schrägseilbrücke mit einem auf das Minimum reduzierten Streckträger fügt sich harmonisch in das Landschaftsbild des reizvollen Neckartals ein. Mit der Gesamtfertigstellung des Projektes im Juni 2011 ist die Gemeinde Zwingenberg nicht nur um ein Ingenieurbauwerk, sondern um ein Wahrzeichen reicher. New building of a single‐lane road bridge across the River Neckar near Zwingenberg, Germany. The community of Zwingenberg is strengthening its infrastructure and tourism by the construction of the new Neckar Bridge. The slight bridge instead of the risky, uneconomic ferry with reduced operating hours due to high water level and poor visibility at night allows the town a save access to the left side of the Neckar. The cable stayed bridge with two pylons and a minimalistic longitudinal beam adds an extra touch to the touristic surroundings. By the time of completion of the project in June 2011 the town of Zwingenberg has added not only an additional civil engineering structure but also a landmark to its cultural heritage.     

A fault‐tolerant workflow management system with Quality‐of‐Service‐aware scheduling for scientific workflows in cloud computing

Cloud computing provides solutions to many scientific and business applications. Large‐scale scientific applications, which are structured as scientific workflows, are evaluated through cloud computing. In this paper, we proposed a Quality‐of‐Service‐aware fault‐tolerant workflow management system (QFWMS) for scientific workflows in cloud computing. We have considered two real‐time scientific workflows, i.e., Montage and CyberShake, for an evaluation of the proposed QFWMS. The results of the proposed QFWMS scheduling were evaluated through simulation environment WorkflowSim and compared with three well‐known heuristic scheduling policies: (a) minimum completion time (MCT), (b) Maximum‐minimum (Max‐min), and (c) Minimum‐minimum (Min‐min). By considering Montage scientific workflow, the proposed QFWMS reduces the make‐span 8.86%, 8.94%, and 5.53% compared with existing three heuristic policies. Similarly, the proposed QFWMS reduces the cost 6.19%, 3.52%, and 3.60% compared with existing three heuristic policies. Likewise, by considering CyberShake scientific workflow, the proposed QFWMS reduces the make‐span 19.54%, 21.41%, and 25.71% compared with existing three heuristic policies. Similarly, the proposed QFWMS reduces the cost 8.78%, 8.40%, and 8.61% compared with existing three heuristic policies. More so, for QFWMS, SLA is neither violated for time constraints nor for cost constraints. While for MCT, Max‐min and Min‐min scheduling policies, SLA is violated 32, 37, and 23 times, respectively. Conclusively, the proposed QFWMS scheduling and management system is one of the significant workflow management systems for execution and management of scientific workflows in cloud computing.
