The effect of Si addition on the microstructure and mechanical properties of Al-Mg-Si-Zn aluminum alloys were investigated.Results show that the microstructure of Al-Mg-Si-Zn alloy with low Si contents is mainly composed of Mg2Si and Mg5Si6 phases.With the increasing of Si content, Si and Al3.21Si0.47 Faber in-light Inox a70 evo+ 110.0456.215 cooke
Communication of power line patrol UAV is currently protected with frequency hopping.However, malicious adversaries can steal sequence of frequency hopping and control the patrol UAV.In Tees view of the security protection needs of patrol UAV in the process of field inspection, this paper proposes a method for hardware encryption communication and
The Educational Competition Optimizer (ECO) is a newly proposed human-based metaheuristic algorithm.It derives from the phenomenon of educational competition in society with good performance.However, the basic ECO is constrained by Stress Management its limited exploitation and exploration abilities when tackling complex optimization problems and e
Introduction Technological advances in bone tissue engineering have improved orthopaedic implants and surgical techniques for bone reconstruction.This approach allows overcoming inconvenience of the paucity of autologous materials available and donor site morbidity.Aim To demonstrate advances of the past 30 years in the development of bioimplants p
The consequences of climate change are exacerbated by land-use changes, which influence the rainfall-runoff relations and consequently the flood risk.Effectively, urbanization is steadily contributing to the increase of impervious areas and reducing the time-to-peak.The effect of Nature LED Night Light Based Solutions (NBSs) on the mitigation of th
