The dynamic fluctuation of stray current is the main characteristic metro causing harm to surrounding buried metal structures. While establishing equivalent circuit model return system, not only mainline but also depot should be considered. diffusion models DC traction power supply system (DTS) in multi-layer soil medium and massive texture are established. They co-simulated with system. (MTSM) verified by an on-site experiment ground potential distribution. In case study, direct grounding...
The existing simulation of rail potential only considers the equivalent DC resistance and 1st-order RL circuit a rail. However, current contains large number harmonic components, which greatly affects calculation potential. To accurately calculate potential, is to tubular conductor considering skin effect. improved reflux system established by vector fitting method (VF), 8th-order foster built. dynamic model multi-trains, multi-stations, over voltage protection device (OVPD) actions...
The DC magnetic bias phenomenon in transformers can result increased noise and harmonic components. This study focuses on the generated by stray currents traction power supply system of neutral grounding under multiple train operation conditions. A two-layer soil model is utilized to calculate geodetic potential, with rail potentials from both mainline depot serving as sources for current within model. Two paths intrusion into transformer via network cable armor layer Main substation have...
Light field (LF) super-resolution has achieved remarkable results with the assumption of only downsampling. However, real-world LF scenes contain multiple degradation effects, which makes it difficult for existing methods to deal hybrid distortions. In this paper, we propose a disentangled feature distillation framework degradations. To reduce learning difficulty, disentanglement mechanism split mixed reconstruction both and denoising into two single task processes. We also enhancement...
To evaluate the effect of wrist dorsiflexion/palmar flexion on median nerve excursion and cross-sectional area in patients with carpal tunnel syndrome.From November 2019 to December 2021, 85 (110 affected wrists) who presented our department were diagnosed syndrome collected classified by severity as mild moderate. Twenty-five healthy controls selected during same period, a total 50 wrists. All volunteers underwent high-frequency ultrasonography measure vertical deviation between transverse...
Stray current in the DC metro system is commonly assessed using circuit or electric field models. Circuit models cannot accurately represent stray diffusion due to track bed and soil resistivity effect on rail-to-earth resistance (RE). Meanwhile, lack detailed device modeling, which hampers their ability comprehensive analyses. To overcome these limitations, a field-circuit coupling model for proposed. The submodel established through direct boundary element method (DBEM) reflux (RS)...
Light detection and ranging (LiDAR) is a ubiquitous tool to provide precise spatial awareness in various perception environments. A bionic LiDAR that can mimic human-like vision by adaptively gazing at selected regions of interest within broad field view crucial achieve high-resolution imaging an energy-saving cost-effective manner. However, current LiDARs based on stacking fixed-wavelength laser arrays inertial scanning have not been able the desired dynamic focusing patterns agile...
Compared with traditional networks, quantum key distribution (QKD) offers the ultimate resources, allowing two remote users to share secret symmetric keys regardless of capabilities eavesdroppers. However, widespread application commercial QKD is still challenging due low photon detection efficiency and extremely high transmission loss. Here we demonstrate a fully phase-encoding system using signal extraction model advantage distillation technology suppress detector noise perform real-time...
The energy feedback system (EFS) is widely accepted to utilize the regenerative braking (RBE) in an urban rail traction power supply (TPSS). However, sharing relationship of RBE between EFS, trains and on-board resistors not clear. In addition, impact EFS operation on has been rarely studied. This paper proposed a hierarchical optimization method for improving utilization shared TPSS through EFS. An optimizing model dynamic start-up voltage threshold established, with objective minimizing...
To analyze the characteristics of lumbar spine-pelvic structure in degenerative spondylolisthesis and its significance spondylolisthesis(DLS).The clinical data 45 patients with simple L4, 5-segment (spondylolisthesis group) admitted from April 2015 to January 2017 were retrospectively analyzed, which compared 50 healthy people complete physical examination same period(control group). Statistical analysis parameters subjects through imaging was performed spine-pelvis DLS patients. The...
