LDP-Slicing: Local Differential Privacy for Images via Randomized Bit-Plane Slicing

Yuanming Cao, Chengqi Li, Wenbo He

Local Differential Privacy (LDP) is the gold standard trust model for privacy-preserving machine learning by guaranteeing privacy at the data source. However, its application to image data has long been considered impractical due to the high dimensionality of pixel space. Canonical LDP …

Research on Performance Parameter Testing Method of Non-Contact Ultrasonic Partial Discharge Detector

Weiwei Zhang, Jing Zhao, Fan Zhang, Chengqi Li

Ultrasonic partial discharge (PD) detection is an important means of PD detection and positioning in power systems. Non-contact ultrasonic PD detection instruments can detect ultrasonic signals in air media and have the advantages of being non-contact and immune to electromagnetic interference. However, …

Performance Verification Testing of PD Sensors in Transformer Integrated Monitoring Devices

Weiwei Zhang, Chengqi Li, Na Li, Zhenjun Zhang

The transformer integrated monitoring device serves as a critical technical means for online transformer monitoring, with the performance parameters of its sensors directly impacting the accuracy and reliability of signal source acquisition. This paper focuses on the performance parameter testing of partial …

The number of maximal matchings in polygon rings

Chengqi Li, Jinhui Yin, Lingjuan Shi

A matching of graph $G$ is maximal if it cannot be expanded by adding any edge to create a larger matching. In this paper, for a hexagonal ring $H$ with $n$ hexagons, we show that the number of maximal matchings of $H$ …
