Though the effects of imposed trunk posture on human walking have been studied, less is known about such locomotion while accommodating changes in ground level. For twelve able participants, we analyzed kinematic parameters mainly at touchdown and toe-off in walking across a 10-cm visible drop in ground level (level step, pre-perturbation step, step-down, step-up) with three postures (regular e...

The author provides a conceptual framework for understanding differences among prosocial, individualistic, and competitive orientations. Whereas traditional models conceptualize prosocial orientation in terms of enhancing joint outcomes, the author proposes an integrative model of social value orientation in which prosocial orientation is understood in terms of enhancing both joint outcomes and...

When examining a rock mass, joint sets and their orientations can play a signiicant role with regard to how the rock mass will behave. To identify joint sets present in the rock mass, measurements of the orientation of individual fractures can be measured on exposed rock faces and the resulting data examined for heterogeneity. In this paper, the EM algorithm is utilized to t mixtures of Kent co...

This paper deals with a predictive model of kinematical performance in 5-axis milling within the context of High Speed Machining. Indeed, 5-axis high speed milling makes it possible to improve quality and productivity thanks to the degrees of freedom brought by the tool axis orientation. The tool axis orientation can be set efficiently in terms of productivity by considering kinematical constra...

Two-dimensional spatial linear filters are constrained by general uncertainty relations that limit their attainable information resolution for orientation, spatial frequency, and two-dimensional (2D) spatial position. The theoretical lower limit for the joint entropy, or uncertainty, of these variables is achieved by an optimal 2D filter family whose spatial weighting functions are generated by...

For an undirected graph G, an orientation of G is defined as a digraph obtained by replacing each edge with an arc. In this paper, we discuss conditions for G to have an orientation that satisfies given demands on the edge-connectivity between disjoint vertex sets.
