UV‐curable inks based on a poly(ethylene glycol) diacrylate (PEGDA) matrix and containing a dispersion of aqueous Ag nanoparticles in different amounts from 10 to 50% are prepared for the fabrication of inkjet printed resistors. The composition is adapted to the inkjet requirements in terms of viscosity, surface tension, and particle size. The gel content, glass transition temperature, conversion, UV‐Vis absorption, morphology, and DC electrical properties of the materials are characterized. It is found that the NPs dispersed in the polymeric matrix realize a percolating path by aligning themselves in chains, which results in a reduction of the percolation threshold. Thus, resistivity is well beyond the dissipative range.

ABSTR ACT. Field data from Stillberg (Switzerl a nd ), provided by SFISAR, have been a nalysed in order to understa nd th e spati al di stribution of snow transported by wind in avala nche-sta rting zones. T he results have bee n used to develop a new empirical model for snowdrift distribu tion. T his model constitutes the "snow-wind modul e" of the knowledge-based comp uter system ca ll ed ELSA.The model is based on a n empirical para meter call ed the wind or "aeoli en" coeffi cient.It represents th e relation between two snow heig hts at a give n place: th e snow acc umulated at the end ofa wind peri od (or wind epi sode) a nd th e snow available for transport at the beginning of the wind period. The wind coeffi cient has been established using fi eld data from the Still berg site.

Field data from Stillberg (Switzerland), provided by SFISAR, have been analysed in order to understand the spatial distribution of snow transported by wind in avalanche-starting zones. The results have been used to develop a new empirical model for snowdrift distribution. This model constitutes the “snow-wind module” of the knowledge-based computer system called ELSA.The model is based on an empirical parameter called the wind or “aeolien” coefficient. It represents the relation between two snow heights at a given place: the snow accumulated at the end of a wind period (or wind episode) and the snow available for transport at the beginning of the wind period. The wind coefficient has been established using field data from the Stillberg site.
