Example: "The car started making an abnormal noise, prompting me to take it to the mechanic for a check-up."
Alternatives: "unusual sound" or "irregular noise".
Considering real experimental results and practical issues, a nonlinear 3-degree of freedom (DOF) torsional model of the clutch system is developed for reducing abnormal noise during vehicle accelerating.
Another method is proposed in the paper based on discriminating pulse-shape and discarding the bad pulse whose shape is distorted as a result of abnormal noise, unusual ballistic deficit or bad pulse pile-up.
This algorithm models the tracked object by using a principle component analysis (PCA) subspace, adopts the idea of noise separation to handle the abnormal noise that appears in the tracking process, and designs the corresponding objective function.
Whenever you hear an abnormal noise with any of your household appliances, call your appliance repair service right away.
Providing that there are no problems with the start-up, no problems with the heater or A/C, and no abnormal noises, it's time to take a ride!
Of these 18 can and other device abrasions, 13 (72%) had electrical abnormalities signified by abnormal impedance, noise, threshold changes, or damaged conductors.
This may be accompanied by abnormal engine noise, heavy smoke or oil dripping from the exhaust.
Does abnormal γ noise (ongoing hypersynchronized γ oscillations) exist in schizophrenic patients?
In humans, if such abnormal γ noise does exist, it would drown the transient (evoked and/or induced) γ responses, for instance the cognition-related coherent γ synchrony.
None of the 19 horses that did not display abnormal respiratory noise during exercise showed dysfunction of the upper airway during an endoscopic examination at rest.
The fact that the majority of horses showing an abnormal respiratory noise during exercise were diagnosed with laryngeal and not pharyngeal instability, could be an explanation.
