On the weekend of June 11-13, the data analytics competition – a hackathon CuValley Hack – took place. DMC and WUST representatives were among 69 teams and almost 300 participants tackling three challenges set by KGHM Polska Miedź S.A. WildLab Team consisting of: Mateusz Góralczyk, Justyna Hebda-Sobkowicz, Anna Michalak, Bartłomiej Ziętek faced the problem of analyzing data from self-propelled mining machines in the context of predicting failures of their components. Despite hundreds of gigabytes of analyzed data and almost 40 hours of hard work, they did not advance to the final six in their category.

The second team, Tremor Hunters, composed of Paweł Trybała, Dariusz Głąbicki and Karolina Owczarz, tried to create a model predicting the occurrence of tremors in the area of underground exploitation. Tremor Hunters made it to the final four of the best teams in their category and presented their results during the live stream and Q&A session with the competition jury. Unfortunately, two competing solutions found more recognition among the judges and won the main prizes.

Various accompanying competitions were also held during the hackathon. We are pleased to announce that the knowledge quiz was completely dominated by representatives of DMC and WUST, who took 5 places among the TOP6!

We are proud to announce that members of DMC (Krzysztof Chudy, Magdalena Worsa-Kozak, and Agnieszka Wójcik) have just published another scientific article. The article presents the results of the preliminary research, which confirmed the existence of not obvious hydrogeochemical stratification in the shaft.

The paper has been published in the special issue of the Water journal entitled “Geochemistry of Groundwater”

We are very happy to announce that our team has grown significantly. Due to our participation in numerous projects, we have acquired several new members.

Yet another conference visited regularly by the members of DMC team is the Machine Diagnostics Symposium (XLVII Ogólnopolskie Sympozjum DIAGNOSTYKA MASZYN) organized annually by Silesian University of Science and Technology in Wisła, Poland. The most commonly discussed topics were: machine diagnostics using vibroacoustic techniques, simulation-aided diagnostics, IT technologies in diagnostics and diagnostics of the means of transportation.
