Relaxation oscillator — A relaxation oscillator is an oscillator in which a capacitor is charged gradually and then discharged rapidly. It is usually implemented with a resistor or current source, a capacitor, and a threshold device such as a neon lamp, diac,… … Wikipedia
Dielectric relaxation as a chemical rate process — Dielectric relaxation was interpreted as a chemical rate process by Walter Kauzmann. According to Kauzmann, relaxation rates may be arranged in two or more distinct groups: Depending on how rapidly they change with temperature. In one group, we… … Wikipedia
Photoacoustic imaging in biomedicine — Photoacoustic imaging, as a hybrid biomedical imaging modality, is developed based on the photoacoustic effect. In photoacoustic imaging, non ionizing laser pulses are delivered into biological tissues (when radio frequency pulses are used, the… … Wikipedia
