The mobile relaying technique is a critical enhancing technology in wireless communications due to a higher chance of supporting the remote user from the base station (BS) with better service quality.This paper investigates energy-efficient (EE) mobile relaying networks mounted on the unmanned aerial vehicle (UAV) while the unknown adversaries try
Abstract Background The prevalence of alcohol and other psychoactive substances is high in biological specimens from injured drivers, while the prevalence of these psychoactive substances in samples from drivers in normal traffic is low.The aim of this study was to compare the prevalence of alcohol and psychoactive substances in drivers admitted to
Alcohol-based fuel is widely used in the catering industry due to the excellent economy, but its explosion risk has not been paid much attention in thermal engineering.In this paper, a serious fire accident caused by the leakage of civil alcohol-based fuel vapor in Northeast China is introduced in detail.A case study is carried out by means of on-s
Underplatform dampers (UPDs) are still in use to reduce the vibration amplitude of turbine blades and to shift the position of resonant frequencies.The dynamics of blades with UPDs is nonlinear and the analysis is challenging from both the experimental and the numerical point of view.A key point in obtaining a predictive numerical tool is the choic
