Abstract Background Several suicide and suicidal behaviour risk factors are highly prevalent in asylum seekers, but there is little insight into the suicide death rate and the suicidal behaviour incidence in this population.The main objective of this study is to assess the burden of suicide and hospital-treated non-fatal suicidal behaviour in asylu
We study the (Delta,D) and (Delta,N) problems for double-step digraphs considering the unilateral distance, which is the minimum between the distance in the digraph and the distance in its converse digraph, obtained by changing the directions of all the arcs.The first problem consists of maximizing the number of vertices N of a digraph, given the m
The Double Permanent Magnet Vernier (DPMV) machine is well known for its high torque density and magnet utilization ratio.This paper aims to investigate the torque generation mechanism and its improved design in DPMV machines for hub propulsion based on the field modulation principle.Firstly, the topology of the proposed DPMV machine is introduced,
