We propose a novel framework of virtual assistant for activating interactions in teaching and learning. The virtual assistant is a robot agent or a CG agent that supports both contents production and presentation. For realizing a virtual assistant, we need the following approaches: 1) Video capturing and editing environment including a virtual assistant, 2) Hardware design of a virtual assistan...

By measuring Drell-Yan massive lepton-pair’s angular distributions, we can identify the polarization of the virtual photon of invariant mass Q which decays immediately into the lepton-pair. In terms of a modified QCD factorization formula for Drell-Yan process, which is valid even if QT ≫ Q, we calculate the massive lepton-pair’s angular distributions at large QT . We find that the virtual phot...

Engineering of industrially applied robot systems using product modeling techniques utilizes the benefits of an advanced solution for integrated computer description of product-production systems. Associative entities in this integrated model communicate modification of any modeled object with any affected modeled objects. This paper discusses a method developed by the authors for model based c...

The goal of the EC-funded IST project ORIGAMI was the development of advanced tools and new production techniques for high-quality and seamless integration of real and virtual content in film and TV productions. In particular, the project focused on pre-production tools for automatic virtual set creation through image-based 3-D modelling of environments and objects. One key goal of the project ...

Unitarity corrections to several electromagnetic processes in collisions of relativistic heavy nuclei are considered. They are due to the unitarity requirement for the S-matrix and correspond to the exchange of light-by-light scattering block between colliding nuclei. We obtain improved results for the corrections to e e− and μμ pair production, as well as new results for unitarity corrections ...

In peripheral relativistic heavy ion collisions at the Large Hadron Collider, jet+jet and photon+jet final states can be produced when a photon from the virtual photon field surrounding the nucleus interacts with a parton in the opposite nucleus (direct production). The virtual photon may also fluctuate into states with multiple gluons and qq pairs (resolved production), opening more channels f...

We are interested in using a virtual environment with a robotic device to extend the strength and mobility of people recovering from strokes by steering them beyond what they had thought they were capable of doing. Previously, we identified just noticeable differences (JND) of a finger's force production and position displacement in a virtual environment. In this paper, we extend this investiga...

An unmanned mining technology for the fully mechanized longwall face automation production is proposed and studied. The essential technology will bring the longwall face production into visualization through the VR (Virtual Reality) and AR (Augmented Reality) combination. Based on the visual theoretical model of the longwall face, the combination of virtual and reality, the real-time interactiv...
