The study of the N 2 and N + 2 optical emissions produced by sprite streamers is useful to estimate the peak electric field in streamer heads, because the energy of the electrons

The different minimum charge moment changes required for streamer initiation found in this paper (320 and 500 C km, respectively, for +CGs and -CGs under typical nighttime

We present new stream expressions compatible with the L IB A UDIO S TREAM , and use them to create an interactive audio graph: hierarchi- cal stream and send - return streams..

In order to do this, we add a new kind of link to the standard hierarchical radiosity links, for which the energy transfer is represented by a radiosity texture, e.g the combination

This is due to the weather conditions used in the simulation (December). As the harvested energy is low compared to Nice for the month of December, the self-consumed energy is also

La nutrition artificielle périopératoire sera recommandée uniquement chez les patients sévèrement dénutris avec une prise en charge nutritionnelle préopératoire de

Le choix de ces composés est destiné à compléter l'étude déià réalisée en série sulfurée, relative à la synthèse et l'acétylation des analogues benzothiophéniques

In conclusion, we presented in this paper an open-source toolkit aimed at enabling casual content creators to render real-world scenes in virtual reality with motion parallax
