Abstract The transformer vibration and noise under the action of voltage current is a serious problem to equipment itself environment. In this paper, newly designed manufactured flexible DC considered. To reduce through proper installation on foundation, characteristics oil tank with different foundation designs are analysed. numerical simulation model two kinds established based FEA. convergen...

The geotechnical study resulted from the need to know foundation land in order properly place investment and includes exploration works performed site area, with aim of providing data necessary solve basic problems specifying aspects related to: stratification on site; physical-mechanical characteristics existing soils; admissible pressures at different levels; probable settlements; framing fie...

We discuss the deletion of a single vertex in a Delaunay tetrahedralization (DT). While some theoretical solutions exist for this problem, the many degeneracies in three dimensions make them impossible to be implemented without the use of extra mechanisms. In this paper, we present an algorithm that uses a sequence of bistellar flips to delete a vertex in a DT, and we present two different mech...
