The need to make use of the growing source of learning material available through the internet and other computer networks confronts educational systems worldwide. The recent idea of creating Virtual Campuses may be viewed as an attempt to counter this challenge and to revive the position of universities as traditional organizers of knowledge. The challenge is twofold: to upgrade the current te...

An audio localization test of moving virtual sound sources was carried out in a spatially immersive virtual environment, using loudspeaker array with vector based amplitude panning for reproduction of sound sources. Azimuth and elevation error in localization was measured. In this experiment the main emphasis was to explore the effect of a distracting auditory stimulus. Eight subjects accomplis...

The purpose of this article is to introduce possibilities of assembling process by using special virtual tools from scientific field named augmented reality (AR) and their implementation on the real examples. After the introduction which sketch basic information about this mentioned scientific area, the first point quickly provides view on the current situation in AR of assembling processes. Th...

in recent years, virtual communities have been significantly popular and almost all of them are targeted for business profitability. in our study, the profitability of these communities for businesses has been analyzed from a commercial perspective. the study considers virtual community as a business model which can have a great impact on consumer purchase decision process. with respect to refe...

A bright photon source that combines high-fidelity entanglement, on-demand generation, high extraction efficiency, directional and coherent emission, as well as position control at the nanoscale is required for implementing ambitious schemes in quantum information processing, such as that of a quantum repeater. Still, all of these properties have not yet been achieved in a single device. Semico...
