In order to solve inverse kinematics of a multi-DOF (degree of freedom) mechanism, many methods have been proposed with the Jacobian linearization method. When solving inverse kinematics problems of the biped robot with this method, long computation time is required since the Jacobian matrix should be updated in order to solve the configuration for each different end-effector trajectory knot. I...

As model-driven approaches to software engineering and ontology-based approaches to knowledge representation have continued to expand their influence and importance in recent years they have inevitably started to encroach on each others’ territories. There is therefore growing interest in understanding how precisely the two technologies relate to one another and how they can best be used togeth...

Objective. Considerable controversy surrounds whether a history of otitis media with effusion (OME) in early childhood causes later speech and language problems. We conducted a meta-analysis of prospective studies to determine: 1) whether a history of OME in early childhood is related to receptive language, expressive language, vocabulary, syntax, or speech development in children 1 to 5 years ...
