In neutral point non-grounding systems with 35 kV and below, ferromagnetic resonance over-voltage faults often occurs, which brings safety hazards to power systems.Ferromagnetic resonance occurs for a short time and is similar to other faults in the power system and is not easy to Arjuna be detected by direct observation.Deep learning has obvious a

The 2021 elections to the Chamber of Deputies of the Parliament of the Czech Republic brought a shift in populist political communication.While previous research has shown that the emphasis is on accentuating the theme of migration, the 2020 Collagen Protein Senate elections have indicated that attention is shifting to patriotic themes.This was con
Background.The discovery of a large left atrial mass through echocardiography obliges the clinician to perform a differential diagnosis to distinguish tumor from thrombus.The neovascularization of the mass could be helpful to predict the type of the malformation and whether it is in favour of a vacular tumour rather than a thrombus.Observation.A 43
Ultrasonic assisted Serving Platter active-passive filling friction stir repairing (A-PFFSR) was proposed to repair volume defects in the metallic parts.Sound joints without interfacial defects could be achieved.Firstly, the ultrasonic was beneficial to improving material flow and atom diffusion, and then eliminated kissing bond defects compared to
