Ice accretion on railway overhead contact wires/conductors can cause various critical operational and safety issues such as overloading, arc formation, mass imbalance, and wire galloping.The focus of this Pouch multiphase numerical study is to understand and analyze the ice accretion physics on railway overhead powerline conductors at various opera
Optimization of Polynomial Transition Curves from the Viewpoint of Jerk Value
The aim of the presented paper is to show the results of shape optimization of NORMAL/OILY HAIR CONDITIONER railway polynomial transition curves (TCs) of 5th, 7th, and 9th degrees through the use of the full vehicle model and new criteria of assessement concerning the jerk value.The search for the proper shape of TCs means that in this work, the ev
Hole Transport Layer Free Perovskite Light-Emitting Diodes With High-Brightness and Air-Stability Based on Solution-Processed CsPbBr3-Cs4PbBr6 Composites Films
Recently, perovskite light-emitting diodes (PeLEDs) have drew widespread attention due to their high efficiencies.However, because of the sensitivity to moisture and oxygen, perovskite luminescent layers are usually prepared in high-purity nitrogen environment, which increases the cost and process complexity of device preparation and seriously hind
