The Madden–Julian Oscillation (MJO) is the dominant mode of intraseasonal variability in the tropics and has a documented influence on extratropical extreme weather through modulation of synoptic atmospheric conditions. MJO phase has been correlated with anomalous tornado and severe hail frequency in the United States (US). However, the robustness...

Historic arch bridges have good gravitational load-bearing capacity. But they are usually vulnerable to seismic loads. Seismic vulnerability analysis and structural behavior assessment of this building requires information on the materials used in the bridge. Due to the limitation of destructive and semi-destructive tests on this constructions and...

Developing methods to predict disastrous natural phenomena is more important than ever, and tornadoes are among the most dangerous ones in nature. Due to the unpredictability of the weather, counteracting them is not an easy task and today it is mainly carried out by expert meteorologists, who interpret meteorological models. In this paper we propo...
