    • A novel approach to feature extraction from gear condition monitoring signals 

      Autor: Bouhafs, Lina; Tamalouzt, Salah; Bouzida, Ahcene
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2025)
      Extracting features from condition monitoring signals of rotating machines is challenging, primarily due to the many potential sources of noise and interference that can corrupt the signals. Additionally, these signals can ...

    • Influence of localised corrosion shape on adhesive damage and a bonded assembly under thermo-mechanical loading 

      Autor: Berrahou, Mohamed; Zahraoui, Mehdi; Hocine, Kamel; Djebbar, Samir; Guermit, Youcef; Benzineb, Hayet
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2025)
      This study explores the damage prediction of repairs on bonded assemblies through a two-part analysis: simulation and experimentation. The effects of corrosion geometry on adhesive and plate damage were evaluated. In the ...

    • Experimental investigation of polyurethane-coated HPFRC panels under direct contact blast 

      Autor: Měrková, Alžběta; Kheml, Přemysl; Perrot, Alexandre; Hála, Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2025)
      High-performance fibre-reinforced concrete (HPFRC) exhibits exceptional resistance to dynamic loading, making it a promising material for structures exposed to blast or impact events. However, when used to produce thin ...

    • Use of the thermo-hydraulic system code RELAP5/MOD3.2 to transient analysis events of the VR-1 reactor 

      Autor: Mátl, Jakub; Fejt, Filip
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2025)
      The article explores the application of the RELAP5 thermo-hydraulic code for transient simulations on the VR-1 research reactor, focusing on reactor vessel nodalisation and coolant stratification above the core. The study ...

    • A Comparative Study of Breast Cancer Detection and Recurrence Prediction Using CatBoost Classifier 

      Autor: Abdu-aljabar, Rana Dhia’a; Aljafaar, Khansaa Dheya; Ameen, Zinah Jaffar Mohammed; Naman, Hala A.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2025)
      In 2019, breast cancer accounted for over one-third of all cancer cases in women in Iraq. It affects both men and women, though it is more common in women. This study delves into advanced machine learning techniques – ...

    • Knowledge and technology transfer in construction engineering: two case studies involving special concrete 

      Autor: Michel-Schneider, Ulrike; Palazzo, Andrea
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2025)
      This research examines the dynamics of knowledge and technology transfer (KTT) within the construction industry while focusing on innovation in special concrete. The study aims to assess two representative cases in different ...
