Abstract Background In Austria around 100 trams are involved in accidents with pedestrians every year.Since the service lives of trams are very high, the probabilities are also high that each tram on the network will be involved in an accident of this kind at least once, highlighting the need of protective designs of tram fronts.However, due to lac

Abstract The rock glaciers of the Swiss National Park were the first in the world where in-situ measurements of surface displacement were undertaken, starting with the pioneering work of Chaix in 1918.Our research is focused on the four rock glaciers described by Chaix, bridging the historical data gap that existed between their early 20th-century

In direction-of-arrival (DOA) estimation with sensor arrays, the background noise is usually modeled to be uncorrelated uniform white noise, such that the related algorithms can be greatly simplified by making use of the property of the noise covariance matrix being a diagonal matrix with identical diagonal entries.However, this model can be easily
