Web 2.0 includes technological and behavioral trends that provide an enlarged added value potential for electronic commerce. This additional potential can be characterized by increased interactivity and multi-mediality, higher degree of standardization and better access to online content. These characteristics determine essentially the development of business models and economic concepts like e...
In this paper, a numerical simulation to analyze the influence of the surrounding water in a turbine runner has been carried out using finite element method (FEM). First, the sensitivity of the FEM model on the element shape and mesh density has been analysed. Secondly, with the optimized FEM model, the modal behaviour with the runner vibrating in air and in water has been calculated. The added...
Offshore oil/gas pipelines are usually installed unburied. Free spans in the line may occur initially by an uneven seabed or be created later due to under-scouring. Free spans are usually unfavourable spots in the submarine pipeline. They are vulnerable to vortex induced vibrations, excessive stresses in the pipe wall or may exhibit undesirable responses to strong ground excitations. In this pa...
