This paper presents a method for managing and modeling a product family as a configurable product. The method enables efficient management of a large number of product variants. The modeling is based on a recently proposed conceptualization of configuration domain, which is a synthesis and extension of the main approaches to configuration. The concepts of(More)
[1] On 4 April 2000, a coronal mass ejection (CME) took place close to the western limb of the Sun. The shock front of the CME hit the Earth's magnetosphere on 6 April. A strong interplanetary southward B Z event in the sheath region caused a magnetic storm that was the second strongest in the year 2000 if quantified by the peak of the Dst index. We have(More)
Geomagnetically induced currents (GICs) in technological conductor systems on the ground are a manifestation of space weather. The basic mechanism of the phenomenon is well understood. Ionospheric currents varying rapidly in time and space are the main cause of large GICs. The most significant events are characterised by a high global geomagnetic activity,(More)
