Deep learning-based wireless channel prediction with propagation feature exploitation

Deep learning based wireless channel prediction can benefit from full exploitation of propagation features, yet how to construct effective inputs for accurate channel prediction remains under-explored. This paper presents a deep learning-based approach that optimizes environmenta...

Over 20.1% Efficiency of Layer‐by‐Layer Organic Photovoltaics by Incorporating High Hole Mobility Material with Crystallinity

ABSTRACT Series of layer‐by‐layer organic photovoltaics (LOPVs) were constructed with polymer D18 as donor and small molecule L8‐BO with self‐dissociation characteristics as acceptor. The high hole mobility and good crystallinity semiconductor C8‐BTBT was deliberately incorporate...

Multi-Axle Reference and Temporal-Consistency Deep SVDD for EMU Traction Motor Bearing Anomaly Detection Using Field Vibration Data

Field vibration monitoring of EMU traction motor bearings is commonly constrained by weak or relative labels, fluctuations in operating conditions, and limited abnormal samples. Under these conditions, learning a normal boundary from a single bearing position may be unstable, and...

Numerical Study on Heat-Drag Reduction for Hypersonic Vehicles via Integrated Aerospike-Jet Configuration

Hypersonic vehicles are constrained by severe aerodynamic heating and drag, which limit both their performance and operational safety. To mitigate these critical issues, this study introduces an integrated aerospike configuration incorporating opposing and lateral jets, designed...
