Based on linear potential flow theory, this study investigates the hydrodynamic performance of a co-located farm with an array floating offshore wind turbines (FOWTs) and photovoltaics (FPVs). In process, to evaluate wave–structure interaction, domain decomposition matched eigenfunction method are applied address boundary value problem for complex-shaped farm, velocity can be decomposed into radiation diffraction problems. Under framework linearized we establish coupled motion equations by...

The traditional X-ray inspection of the tension clamp transmission line requires power outage to climb tower. It will be an inevitable trend future development for live work gradually replace failure overhaul. For 110/220kV multi-circuit operations on same tower, this paper proposes two online and offline schemes, namely, UAV guide/ground wire pulley hoisting method tower method, strict safety distance requirements are given. prototype detection device was subjected arc discharge simulation...
Fewer power losses are required for transmission lines; thus, the need improving operating and maintenance level of loss is becoming an urgent need. Although design layout standards high-voltage electric energy metering device in distribution network have gradually become complete competent, still some defects exist device. First, owing to higher requirements power-cut, replacement speed 10kV devices much slower than that low-voltage meters. Second, due failure on-site calibration can only...
Most of the measurements nature lightning current time-domain waveforms were taken at tall towers and buildings. In order to study influence on measurement, transmission line (TL) model return stroke was applied calculate different positions tower.

Simulation result shows that obtained top tower is most close real current, amplitude influenced by a few factors, such as height tower, reflectance ground rise-time waveform....
In high-energy physics, precise measurements rely on highly reliable detector simulations. Traditionally, these simulations involve incorporating experiment data to model responses and fine-tuning them. However, due the complexity of data, tuning simulation can be challenging. One crucial aspect for charged particle identification is measurement energy deposition per unit length (referred as dE/dx). This paper proposes a data-driven dE/dx method using Normalizing Flow technique, which learn...
