How Crouch Gait Can Dynamically Induce Stiff-Knee Gait

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...

Modelling and simulation of a rate controlled manipulator ARM

Guelman, M. (author)

The mathematical model of a space based manipulator arm with a rate controlled end effector is defined and the recursive algorithms for the computation of the basic djmamic functions are formulated. A digital simulation of this system is implemented and preliminary results are presented. Actual running times for the simulation In a VAX 750...

Pin-pin resonance as a reference in determining ballasted railway track vibration behaviour

De Man, A.P. (author)

Pin-pin resonance is one of the most significant preferred vibration modes of beams, which are supported at equal distances, such as rails at sleepers in railway track structures do. Pin-pin resonance is a vibration that appears in one basic (first) mode and several higher modes, however the basic mode will have the highest amplitudes. In...
