Based on the comparison of experimental results to field study results, the relevance and significance of various similitude parameters for snowdrift modelling is discussed. A series of wind tunnel model tests were carried out on a single building and groups of buildings, both on-ground and above-ground. Results of snowdrift profiles and volumes are presented.
When high-speed trains run on a snowy railway line in cold weather, a large amount of snow and ice will accumulate on the brake calipers, which can lead to huge safety problems. In this paper, to s...
We prove that groups acting geometrically on delta-quasiconvex spaces contain no essential Baumslag-Solitar quotients as subgroups. This implies that they are translation discrete, meaning that the translation numbers of their nontorsion elements are bounded away from zero.
