Book ChapterDOI
The Influence of EP/AW Addition in the MQL Method on the Parameters of Surface Geometrical Structure in the Process of Turning 316L Steel
Radoslaw W. Maruda,Szymon Wojciechowski,Grzegorz Królczyk,Danil Yu. Pimenov,Stanisław Legutko +4 more
TL;DR: In this article, the authors compared four cooling methods for turning austenitic steel: dry cutting, MQL, MQCL and MQL + EP/AW, and found that the MQL cooling method is a good alternative to dry cutting in machining of hard-to machine steels.
Journal ArticleDOI
Fusion Deconvolution for Reliability Analysis of A Flywheel-Battery Hybrid Energy Storage System
TL;DR: In this article , a new fusion deconvolution is proposed to perform reliability analysis on the hybrid flywheel-battery energy storage system, which is able to smooth the battery charging/discharging; harmful impact can be filtered by the flywheel to reduce battery damage and extend battery life.
Journal ArticleDOI
Measuring Shape Parameters of Pearls in Batches Using Machine Vision: A Case Study
TL;DR: In this paper , a method of contacting pearls segmentation based on the pit detection was proposed, where multiple pearl images were obtained by backlit imaging, the quality of the pearl images was improved through appropriate preprocessing, and the contacted pearl area was extracted by calculating the area ratio of the connected domains.
