Two new articles published in MSSP

We are happy to announce that members of DMC recently published two articles in Mechanical Systems and Signal Processing journal. Both of them present newly developed vibration signal processing techniques mainly aimed for machine diagnostics purposes (see references below). The work presented in those papers has been funded by MAMMA and OPMO projects. Full citations can be found on the research page.

DMC at Szkoła eksploatacji podziemnej

On Monday, February 24~$^{th}$, the XXIX School of Underground Exploitation began in Krakow. For three days, scientists and representatives of mining companies discussed the future of the industry in the era of energy transformation. There were many sessions related to the mining industry, a discussion panel, and interactive voting.

DMC at the Nonstationarity Workshop

At the beginning of this February, members of the DMC group attended the Workshop on Nonstationary Systems and Their Applications in Gródek nad Dunajcem in Poland. This annual event gathers mathematicians and other scientists from all over the world to discuss the recent frontiers of the research on the topics such as nonstationary and cyclostationary analytics, data science, signal processing, stochastics, and many others.
