Low current sensitivity and insufficient system robustness are two significant obstacles preventing widespread use of all-fiber current sensors (AFCSs). We demonstrate a novel AFCS combining a fiber-loop architecture and a reflection scheme. The design has not only the capable of increasing current...

This study is the first to investigate the parametric instability of multi-segment conical shells (MSCSs) under periodic spin speed. The artificial spring simulates the general boundary constraints and the constraints between shell segments. Based on Donnell’s shell theory and the Lagrange equation,...

Finding an exact ground state of a three-dimensional (3D) Ising spin glass is proven to be an NP-hard problem (i.e., at least as hard as any problem in the nondeterministic polynomial-time (NP) class). Given validity of the exponential time hypothesis, its computational complexity was proven to be n...

Radiography is of importance in the diagnosis of atlantoaxial dislocation (AAD), and it is the basic imaging technique. However, it should not be the sole diagnostic modality, especially in complex or unclear cases. Conventional X-ray includes an open-mouth odontoid view and a cross-table lateral vi...

The significance of coal mine gas control in the field of engineering cannot be underestimated [...]

Traditional model predictive current control (MPCC) is heavily dependent on the accuracy of motor parameters and incurs high computational costs. To address these challenges, this paper proposes an enhanced model-free predictive current control (MFPCC) strategy based on ultra-local models (ULMs). In...
