Construction of optimal zero correlation zone sequence set [PDF]

Tongxin xuebao, 2020
The construction of zero correlation zone (ZCZ) sequence set was researched based on perfect sequences and orthogonal sequence set.With the method of constructing on finite field,the optimal zero correlation zone sequence sets were constructed,by ...

Research on zero-sequence circulating current of bidirectional converters

机车电传动
The bidirectional converter device, featuring multiple converters in parallel on both AC and DC sides, employs carrier phase-shifting control. This approach can significantly enhance system capacity and reduce grid current harmonics; however, it also ...

Zero product preserving bilinear operators acting in sequence spaces

Karpatsʹkì Matematičnì Publìkacìï, 2020
Consider a couple of sequence spaces and a product function $-$ a canonical bilinear map associated to the pointwise product $-$ acting in it. We analyze the class of "zero product preserving" bilinear operators associated with this product, that are ...

A fault line selection method for flexible grounding systems based on zero-sequence current phase variation

Zhejiang dianli
To address the poor tolerance to transitional resistance and incomplete utilization of fault information in grounding protection for flexible grounding systems， a fault line selection method based on current phase variation is proposed.

Zero-shot Sequence Labeling for Transformer-based Sentence Classifiers

, 2021
We investigate how sentence-level transformers can be modified into effective sequence labelers at the token level without any direct supervision. Existing approaches to zero-shot sequence labeling do not perform well when applied on transformer-based ...

Research on Fault-Tolerant Operation Strategy of Permanent Magnet Synchronous Motor with Common DC Bus Open Winding Phase-Breaking Fault

Energies, 2022
In some key areas, fault-tolerant control is usually needed in order to enable the motor to operate continuously in fault mode. Given that it is difficult to detect the zero-sequence current of the open winding permanent magnet synchronous motor after ...

Domain-Aware Continual Zero-Shot Learning

, 2021
We introduce Domain Aware Continual Zero-Shot Learning (DACZSL), the task of visually recognizing images of unseen categories in unseen domains sequentially. We created DACZSL on top of the DomainNet dataset by dividing it into a sequence of tasks, where
