Acoustic Impedance Mismatch Sound travels easily through materials that are similar in density. A regular windshield doesn’t do much to stop noise because sound waves pass right through the ...
A recent study in Engineering uncovers new insights into detecting hydrate blockages in subsea oil and gas pipelines. As ...
Acoustically, the presence of hydrates affects the propagation of acoustic waves, and the impedance mismatch between hydrates and the surrounding medium can be used for detection. Electrically ...
However, both USI and PAI suffer from a significant reduction in signal quality when ultrasound signals pass through the skull. The high acoustic impedance mismatch between skull and soft tissue (or ...
Acoustically, the presence of hydrates affects the propagation of acoustic waves, and the impedance mismatch between hydrates and the surrounding medium can be used for detection. Electrically, ...
7 Mismatch negativity is elicited when a violation of the regularity of acoustic stimuli is detected, reflecting involuntary attention ... Disposable surface electrodes were then positioned in Fz, Fpz ...
Load-mismatched power detecting and automatic impedance reconfiguration techniques are demonstrated. In the load-mismatched power detecting technique, a novel buck circuit is proposed to cope with ...
In parallel compensated receivers, capacitors balance the inductance of the receiver coil to achieve resonance, reducing circuit impedance ... modulation creates a mismatch between the modulated ...
