We discuss the use of stochastic collocation for the solution of optimal control problems which are constrained by stochastic partial differential equations (SPDE). Thereby the constraining SPDE depends on data which is not deterministic but random. Assuming a deter-ministic control, randomness within the states of the input data will propagate to the(More)
The assessment of biodurability of man-made vitreous fibers is essential to the limitation of health hazards associated with human exposure to environments in which respirable fibers are present. In vitro acellular systems provide effective test methods of measuring fiber solubility provided care is taken to select the most suitable solvent and test(More)
Percutaneous radiofrequency (RF) ablation is becoming a standard minimal invasive procedure for treatment of primary liver tumors. In clinical practice, knowledge about geometry and expected size of the coagulation is essential to prevent local tumor recurrence. Particularly the heat-sink effects of large vessels in the vicinity of the electrode may lead to(More)
