Maximizing maximal angles for plane straight-line graphs
Aichholzer, Oswin; Hackl, Thomas; Hoffmann, Michael; Huemer, Clemens; Pór, Attila; Santos, Francisco; Speckmann, Bettina; Vogtenhuber, Birgit (2013-01)
Article
Accés restringit per política de l'editorialLet G=(S,E) be a plane straight-line graph on a finite point set S⊂R2 in general position. The incident angles of a point p∈S in G are the angles between any two edges of G that appear consecutively in the circular order ... -
The role of hardness and roughness on the wear of different CoCrMo counterfaces on UHMWPE for artificial joints
González-Mora, V. A.; Hoffmann, Michael; Stroosnijder, R.; Gil Mur, Francisco Javier (Springer, 2011)
Article
Accés obertWear tests were carried out to study the effect of the hardness and roughness with various counterface materials on UHMWPE wear behaviour. The materials used as counterfaces were based on varieties of CoCrMo: 1) forged ... -
Uni and multidirectional wear resistance of different crosslinking degrees in UHMWPE for artificial joints
González-Mora, V. A.; Hoffmann, Michael; Stroosnijder, R.; Espinar, Eduardo; Llamas, L. M.; Fernández-Fairén, Mariano; Gil Mur, Francisco Javier (Springer, 2011)
Article
Accés obertThe aim of this work was to study the effect of UHMWPE crosslinking on wear performance. Differently treated UHMWPEs were studied by means of unidirectional and multidirectional wear tests. Unidirectional tests simulate ...
