Structural analysis of a third-class ten-link mechanism with two complex links

open access: yesTrudy Odesskogo Politehničeskogo Universiteta
The basis of a technological machine is a mechanism whose main task is to convert the predetermined mechanical motion of the moving link of the initial mechanism into the motion of the driven link required to perform a technological operation, with the ...

Link clustering reveals structural characteristics and biological contexts in signed molecular networks.

open access: yesPLoS ONE, 2013
Many biological networks are signed molecular networks which consist of positive and negative links. To reveal the distinct features between links with different signs, we proposed signed link-clustering coefficients that assess the similarity of inter ...
