The paper deals with the problem of motion data classification based on dynamic time warping transform. In the preliminary stage the selection of pose configuration parameters by hill climbing procedure is carried out. To construct dissimilarity matrices Euler angles and unit quaternion distance functions are taken into consideration and compared. To examine proposed approach gait database containing data of 30 different humans is used. The obtained results are satisfactory. The classification has over than 90% accuracy and joint selection allows to reduce dimensionality of pose configuration space noticeably.

    This paper argues for a broadly dispositionalist approach to the ontology of Bohmian mechanics (BM). It first distinguishes the 'minimal' and the 'causal' versions of Bohm's theory, and then briefly reviews some of the claims advanced on behalf of the 'causal' version by its proponents. A number...
