Contrastive learning is a promising approach to unsupervised learning, as it inherits the advantages of well-studied deep models without dedicated and complex model design. In this paper, based on bidirectional encoder representations from transformers (BERT) long-short term memory (LSTM) neural networks, we propose self-supervised contrastive (SCL) well few-shot (FCL) with data augmentation (U...

Fault Current Limiters are used in a wide array of applications from small circuit protection at low power levels to large scale high power applications which require superconductors and complex control circuitry. One advantage of passive fault current limiters (FCL) is the automatic behavior that is dependent on the intrinsic properties of the circuit elements rather than on a complex feedback...

Fault location is an interesting subject in power grids. On the other hand, the application of fault current limiter (FCL) has been increasing in power network and causes some problems in operation of protection systems. This paper studies the application of FCL in power system and its effect on one-ended simple reactance fault location methods. In these methods, only voltages and currents of t...

In this paper, a second order sliding mode control scheme is utilized for outer voltage loop of three-phase fault current limiter-based dynamic restorer (FCL-DVR) instead conventional proportional integral/proportional resonance (PI/PR) controller. The new strategy improves the performance FCL-DVR against distortion. Furthermore, by using proposed robustness controller, can smoothly switch betw...

This paper summarizes the work done to show finite element modeling results on a high temperature superconductor fault current limiter (FCL). The paper also gives the small mock-up design of the matrix FCL and its finite element model (FEM). It also discusses the limitations of the FEM and explains how the results from the FEM compare with the experimental data derived for the configuration. A ...

Dynamic voltage restorer (DVR) is a protecting device for sensitive loads which compensates grid fluctuations. Although using fault current limiting devices (FCL) method of and electrical networks against short circuits. In recent years, some methods have been proposed to combine these two reduce the cost converters use benefits each simultaneously. A new topology control DVR an FCL presented i...

The Universal Soil Loss Equation (USLE) and revised USLE (RUSLE) are often used to estimate soil erosion at regional landscape scales, however a major limitation is the difficulty in extracting the LS factor. The geographic information system-based (GIS-based) methods which have been developed for estimating the LS factor for USLE and RUSLE also have limitations. The unit contributing area-base...

LS is a very important factor in erosion evaluation. Slope gradient and slope length is used to calculate LS factor. However a major limitation is the difficulty in extracting the LS factor at regional landscape scales. The geographic information systembased (GIS-based) methods which have been developed for estimating the slope length for USLE and RUSLE model also have limitations. he unit cont...

Rice (Oryza sativa L.) is the only cereal crop that possesses the ability to germinate under flooded or other oxygen-deficient conditions. Rapid elongation of the coleoptile is a perfect response to flooding during germination, with coleoptile length differing among various rice varieties. Despite multiple studies have uncovered valuable information concerning this trait by focusing on the phys...

The classical follicular variant of follicle center lymphoma (FCL-fo) is associated with the chromosomal translocation t(14;18)(q32;q21). However, the sole presence of this translocation is not sufficient for malignant transformation, as demonstrated by experiments in a transgenic mouse model. Most of the secondary changes, which play a central role in tumor development and progression and whic...
