A method, implemented at least in part by a computing device, for organizing concept-related information available on-line. The calculating the indirect effect includes correcting a surface profile at the first computational element on the basis of a surface structure around the first computational element, and calculating the indirect effect on the basis of the corrected surface profile at the first computational element. Slots are defined through the top wall of the hub facing to the magnet ring. If a first token used to create the authenticated rights locker access request has been fully redeemed, a new token that authenticates future access to a rights locker corresponding to the digital content is obtained. The system thus provides a reduction of the link impact force FL and the resultant impact energy E.
