This paper explores the recognition of expressed emotion from speech and facial gestures for the speaker-dependent case. Experiments were performed on an English audio-visual emotional database consisting of 480 utterances from 4 English male actors in 7 emotions. A total of 106 audio and 240 visual features were extracted and features were selected with Plus l-Take Away r algorithm based on Bh...

We study the Lagrangian dynamics of systems of N point vortices and passive particles in a two-dimensional, doubly periodic domain. The probability distribution function of vortex velocity, pN , has a slow-velocity Gaussian component and a significant high-velocity tail caused by close vortex pairs. In the limit for N→` , pN tends to a Gaussian. However, the form of the single-vortex velocity c...
