Aim
The aim of this study was to describe and analyse the degree of second victim syndrome and the desire for supports among nurses working in regional hospitals in China.
Background
The evidence on the prevalence of second victim among health care workers remains inconsistent and has rarely focused on the regional level.
Methods
A quantitative, descriptive, survey‐based, online, cross‐sectional...
This article studies the classical MDS and dwMDS location algorithm. On this basis, the relaxation iteration method is introduced to replace SMACOF algorithm as optimization objective function. The results showed that the network connectivity increases with the increased communication radius, and it has a good effect that the relaxation method of positioning results in the node density from 2 to 4...
A new power management circuit which includes energy conversion sub-system (photovoltaic battery),energy storage sub-system(lithium-ion battery+ultracapacitor energy conversion sub-system) and power management sub-system is designed. The power management circuit provides electricity to the wireless sensor node. The energy conversion sub-system adopts four solar photovoltaic batteries to capture energy...
Sustainable operation of sensor nodes powered by limited lifetime batteries is a key challenge. Environmental energy harvesting is an attractive technique to forestall this energy crisis of wireless sensor networks. To realize a self-sustaining wireless sensor node, the objective of this research is to develop a new power management circuit which is supplied with four photovoltaic batteries which...
