The asymmetric unit of the title compound, C44H30O2, contains two independent mol-ecules in which the terminal rings of the terphenyl element are inclined at angles of 36.3 (1) and 22.5 (1)° with respect to the central ring and the dihedral angles between the fluorenyl units are 72.3 (1) and 62.8 (1)°. In the crystal, pairs of O-H⋯O hydrogen bonds link the(More)
In this paper we present an approach for real-time gesture recognition using the Kinect sensor and a set of machine learning techniques. We propose a novel approach for feature extraction using measurements on skeletal joints. We select a set of simple gestures and construct a data set. We train classifiers under the assumptions that they shall be evaluated(More)
