Geometric information alone is not sufficient to guide foot placement in a robotic device. A travel path may be firm or soft, slippery or sticky and will thus affect locomotion. In humans, associations are made between various travel surfaces and gait modification. If a preferred foot position is unavailable, an alternate is selected. This selection is(More)
To discuss the portability of human natural language technology, it is necessary to define the portability precisely first. If one claims that his or her language technology works for other languages, how can we verify such claim when every language has a different set of features, i.e. speech or text tagging system?

A patient journey in the hospital may include many departments or units. Making safe and smooth transitions within the hospital is of significant importance. This paper introduces a Markov chain model to study patient transitions between emergency department, intensive or critical care unit, and hospital ward. An iteration method is presented to evaluate(More)
