Study washboarding phenomenon in fame sawing machines
PublikacjaPraca dotyczy zjawiska washboarding cechującego się powstawaniem na piłowanej powierzchni sinusoidalnego profilu w przekroju poprzecznym i wzdłużnym. Wzór ten jest efektem drgań poprzecznych piły. Przedstawiono wyniki analiz teoretycznych oraz badań eksperymentalnych, w których wykazano, że zjawisko w przypadku pilarek ramowych jest efektem drgań wymuszonych brzeszczotu oraz regeneracji powstałej fali pierwotnej.

Study of Slip Effects in Reverse Roll Coating Process Using Non-Isothermal Couple Stress Fluid
PublikacjaThe non-isothermal couple stress fluid inside a reverse roll coating geometry is considered. The slip condition is considered at the surfaces of the rolls. To develop the flow equations, the mathematical modelling is performed using conservation of momentum, mass, and energy. The LAT (lubrication approximation theory) is employed to simplify the equations. The closed form solution for velocity, temperature, and pressure gradient...

A Robust Random Forest Model for Classifying the Severity of Partial Discharges in Dielectrics
PublikacjaPartial Discharges (PDs) are a common source of degradation in electrical assets. It is essential that the extent of the deterioration level of insulating medium is correctly identified, to optimize maintenance schedules and prevent abrupt power outages. Temporal PD signals received from damaged insulation, collected through the IEC-60270 method is the gold standard for PD detection. Temporal signals may be transformed to the frequency...
