In this paper, we propose the implementation of a safety device that generates an alarm sound or braking operation to reduce the risk of accidents.It reduces the exposure of risks due to non-wearing by supplementing the function of the helmet for safety.For machine learning, the safety state is learned by using two types of sensing data, and when a

With the improvement of the conversion efficiency of LED chip and fluorescent material and the increasing demand for high-brightness light sources, LED technology has begun to move toward the direction of high-power.However, there is a huge problem that high-power LED must face with a large amount of heat generated by high PTO Clutches power causin

Background: There are still conflicting results on thepostoperative consequences of patients with hip and femoralfractures based on the type of anesthesia.The aim of this studywas to compare mortality and morbidity of general and spinalanesthesia in patients undergoing hip and femoral fractures.Methods: In this analytical cross-sectional study, the

Abstract Background Gender-based violence (GBV) particularly against women is unfortunately common during armed conflicts.No rigorous and comprehensive empirical work has documented the extent of GBV and its consequences that took place during the two years of devastating armed conflict in Northern Ethiopia.This study aims to assess GBV and its con
