Karssen, J.G. (author), Wisse, M. (author)Large disturbances can cause a biped to fall. If an upcoming fall can be detected, damage can be minimized or the fall can be prevented. We introduce the multi-way principal component analysis (MPCA) method for the detection of upcoming falls. We study the detection capability of the MPCA method in a simulation study with the simplest walking...journal article 2008

Hobbelen, D.G.E. (author), Wisse, M. (author)Limit cycle walkers are bipeds that exhibit a stable cyclic gaitwithout requiring local controllability at all times during gait. A well-known example of limit cycle walking is McGeer’s “passive dynamic walking,” but the concept expands to actuated bipeds as involved in this study. One of the stabilizing effects in limit cycle walkers is the...journal article 2008

Wisse, C.J. (author), Smeulders, D.M.J. (author), Chao, G. (author), Van Dongen, M.E.H. (author)The classical theory of wave propagation in elastic cylinders is extended to poro-elastic mandrel modes. The classical theory predicts the existence of undamped L modes and damped C, I, and Z modes. These waves also appear in poro-elastic mandrels, but all of them become damped because of viscous effects. The presence of the Biot slow bulk wave...journal article 2007

Van der Krogt, M.M. (author), Bregman, D.J.J. (author), Wisse, M. (author), Doorenbosch, C.A.M. (author), Harlaar, J. (author), Collins, S.H. (author)Children with cerebral palsy frequently experience foot dragging and tripping during walking due to a lack of adequate knee flexion in swing (stiff-knee gait). Stiff-knee gait is often accompanied by an overly flexed knee during stance (crouch gait). Studies on stiff-knee gait have mostly focused on excessive knee muscle activity during (pre...journal article
