Abstract Deep learning for bearing fault diagnosis often requires a large quantity of comprehensive data to give support in the field rotating machinery diagnosis. However, large-quantity datasets model training are difficult obtain actual working environments. Therefore, problems under practical conditions considered few-shot problems. Meta-learning can be adopted solve these Traditional meta-learning methods, however, lead overfitting, and shallow neural networks usually used avoid...
Abstract Variations in bearing operating conditions may cause a shift the feature distribution of fault signals, weakening generalization ability diagnosis model. Traditional methods with domain adaptation (DA) extract invariant cross-domain features, but they are mostly applied to single-source domain. In case multi-source transfer, however, determining which source has better transfer effect target is difficult. this paper, we aim combine transferable knowledge contained all available...
The ability of electrospun polyvinylidene fluoride (PVDF) fibers to produce piezoelectricity has been demonstrated for a while. Widespread applications PVDF as an energy conversion material, however, have not materialized due the random arrangement fabricated by traditional electrospinning. In this work, developed 3D electrospinning technique is utilized fabricate micro wall made up densely stacked in fiber-by-fiber manner. Results from X-ray diffraction (XRD) and Fourier transform infrared...
The regenerator of the pulse tube refrigerator (PTR) operates with oscillating pressure and mass flow, so a proper description heat transfer characteristics flow in is crucial. In this paper, one-dimensional model based on Lagrangian representation developed to simulate PTR. continuity equation, momentum equation energy are solved iteratively using SIMPLER algorithm. Darcy-Brinkman-Forchheimer used thermal non-equilibrium implemented equation. employed describe thermodynamics fluid parcels...
In this paper, a power allocation problem for cooperative communication network with non-orthogonal multiple access and simultaneous wireless transmission (C-NOMA-SWIPT) is considered. We both consider the half duplex NOMA SWIPT full network. There are two users in each cluster. The strong user receives information energy from BS using splitting, then decode forward relay data weak user. On purpose of fairness rate, we formulated optimization to maximize minimum achievable rate cluster,...
