Many musical interfaces have used the musical conductor metaphor, allowing users to control the expressive aspects of a performance by imitating the gestures of conductors. In most of them, the rules to control these expressive aspects are predefined and users have to adapt to them. Other works have studied conductors’ gestures in relation to the performance of the orchestra. The goal of this s...

The present paper reports on results of a study investigating changes of lip features, larynx position and acoustics caused by smiling while speaking. 20 triplets of words containing one of the vowels /a:/, /i:/, /u:/ were spoken and audiovisually recorded. Lip features were extracted manually as well as using a 3D motion capture technique, formants were measured in the acoustic signal, and the...

Usually tracking objects by means of a moving camera means solving the problem of segmenting its motion from the background and maintain the gaze on it. Usually key points, i.e. features like corners, are matched throughout consecutive frame to register frames and detecting objects or to compute a fixation point on the object of interest. None of the methods proposed so far investigates how, mo...

We describe a method to dynamically synthesize believable, variable stride, and variable foot lift motions for human walks and climbs. Our method is derived from a single motion captured walk sequence, and is guided by a simple kinematic walk model. The method allows control in the form of stride and lift parameters. It generates a range of variations while maintaining individualistic nuances o...

background: boron neutron capture therapy (bnct) is a very promising treatment for patients suffering gliobastoma multiforme, an aggressive type of brain cancer, where conventional radiation therapies fail. thermal neutrons are suitable for the direct treatment of cancers which are located at near-tissue-surface deep-seated tumors need harder, epithermal neutron energy spectra. materials and me...

carbon capture and storage (ccs) systems have relevant energy consumption associated with the co2 capture process. it causes an energy efficiency reduction that diminishes the economic interests and increases the technical uncertainty of these systems. with the objective of improving the system perform-ance and reducing thermodynamic inefficiencies, the exergy analysis has been traditionally ap...
