New article published

Once again, we are proud and happy to announce that members of DMC have just published another scientific article. In the new work a procedure for vibration analysis of the sieving screens used in the raw materials industry is presented. The paper has been published in the special issue of Sensors journal entitled “Sensing Technology and Data Interpretation in Machine Diagnosis and Systems Condition Monitoring”.

The research that led to the publication of this paper has been funded by OPMO project.

Growing appetites for academic development

Three of the DMC members have just started a new chapter in their career. Aleksandra Banasiewicz, Adam Wróblewski and Bartłomiej Ziętek, at the end of this week became brand new Ph.D. students of the interdisciplinary Doctoral School of WUST.

They are going to excel and develop in the area of Environmental Engineering, Mining and Energetics making advantage of the skills obtained due to their responsibilities in DMC and enriching our team by their freshly acquired knowledge.

We wish you all the best on the new adventure path!

Pavlo Krot on the Virtual Conference on Mechanical Fatigue

There is no time to waste, waiting for the conferences in classic form. Our team knows it very well, hence the research work is in full swing and we are happy to present its fruits in the virtual world.

We are proud to announce that the member of DMC’s Mechatronics / Reliability group – Pavlo Krot, Ph.D. presented three of his new works on fhe first Virtual Conference on Mechanical Fatigue (VCMF 2020) organised by the University of Porto, the Wrocław University of Science and Technology and the ESIS/TC12 Technical Committee (European Structural Integrity Society – ESIS). The articles presented below are an effect of the international and interdisciplinary cooperation between Pavlo and other Ukrainian and Polish researchers from:

  • Z.I. Nekrasov Iron and Steel Institute,
  • Ukrainian State University of Chemical Technology,
  • Lviv Polytechnic National University,
  • Admiral Makarov National University of Shipbuilding,
  • DMT GmbH & Co.,
  • KGHM Polska Miedź S.A and
  • Faculty of Geoengineering, Mining and Geology of WUST.

Robots left the lab to try their hands in the underground world

Last week was a very intense time for DMC. Directly after Festival of Knowledge, robots, drones and measurement equipment got packed and prepared to be taken for an underground adventure in the corridors of the former gold and arsenic mine in Złoty Stok (meaning ‘golden hillside’). Researchers from the Faculty of Geoengineering, Mining and Geology, hand in hand with young scientists from the Faculty of Mechanical Engineering tried their best, facing the problems that await electronic devices in mines.

Wheeled, tracked or legged undercarriage: what is the best choice for an underground challenge?

Zaproszenie na Dolnośląski Festiwal Nauki

Zespół Digital Mining Center Wydziału Geoinżynierii, Górnictwa i Geologii Politechniki Wrocławskiej w ramach Dolnośląskiego Festiwalu Nauki serdecznie zaprasza na warsztaty on-line na temat:

Górnictwo – maszyny i roboty – rzeczywistość i świat wirtualny.

Przygotujcie się na przygodę z cyfrowym górnictwem. Opowiemy o tym jak roboty i drony pomagają górnikom w pracy i jak pozwalają pracować bezpieczniej. Pokażemy prawdziwą kopalnię dzięki możliwościom technologii filmowania 360. Pokażemy testy nowoczesnych urządzeń na co dzień wspierających pracę pod ziemią. Opowiemy o ciekawych międzynarodowych projektach, współfinansowanych przez EIT KIC Raw Materials, które realizuje DMC.

Warsztaty są otwarte dla wszystkich chętnych uczestników bez limitu miejsc i bez wcześniejszych zapisów.

Odbędą się on-line na platformie ZOOM w 3 terminach do wyboru:

• 21. września 2020r. o godz. 10.00 – 11.00

• 22. września 2020r. o godz. 10.00 – 11.00

• 23. września 2020r. o godz. 10.00 – 11.00

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.
