Non-ideal measurement computed tomography (CT) employs suboptimal imaging protocols to expand CT applications. However, the resulting trade-offs degrade image quality, limiting clinical acceptability. Although deep learning methods have been used to enhance non-ideal measurement CT images, their reliance on large training datasets …

With the further increase in investment in power distribution network construction, traditional project management methods are confronted with the challenge of quantifying and identifying the bottleneck of efficiency in each project execution stage from "reservation, project initiation, implementation and commissioning". Therefore, this …

We investigate the communication data enhanced direct position determination (DPD) for uplink multi-antenna orthogonal frequency division multiplexing (OFDM) systems. Different from prior related works, both pilot and unknown data signals are employed to estimate the positions of the mobile station (MS) and …

This research proposes a novel adaptive virtual synchronous generator (VSG) control strategy for a photovoltaic-energy storage (PV-storage) hybrid system. In comparison to the traditional VSG control approach, the adaptive control strategy presented in this research markedly diminishes the fluctuations in output power. …

The given power and grid frequency disturbances can cause transient oscillations and steady-state deviations in the output power of a virtual synchronous generator (VSG), which can be effectively addressed by adding transient damping. However, this approach may result in significant power overshoot. …

Superconducting electrodynamic suspension (SCEDS) possesses superiority over others in self-stability, technology maturity, and great levitation gap, rendering it the optimal alternative for sub-sonic travelling integrated with the evacuated tube. However, the coupling relationship among tube and SCEDS train remains ambiguous. As a …
