  - Year 2012

  W artykule zaproponowano nową metodę aproksymacji zmian stężenia znacznika w badaniach pCT płuc. Zmiany stężenia znacznika są skanowane z częstotliwością kilkakrotnie większą niż częstotliwość oddechu. Metoda opiera się na spostrzeżeniu, że częstotliwość występowania pików na krzywych zmian stężenia znacznika jest równa częstotliwości oddechu badanego. Zaprezentowano przykładowe dopasowanie funkcji regresji w postaci krzywej Gaussa...

• Instantaneous power signal measurements for bearing diagnostics

  Open Research Data

  open access

  • A. Dzwonkowski
  • D. Świsulski

  Bearing diagnostics can be carried out based on the method, which relies on the measurement and analysis of the variability of the signal instantaneous power, defined as the product of instantaneous current and voltage power supplied to the engines. Bearing damage causes the appearance of deformations, which are in the form of additional harmonic components...
