The method assumes small amplitude oscillations without flow separation. Combustion instabilities are typically violent pressure oscillations in a combustion chamber. Analyses suggest that ocean current fluctuations can adequately account for recent glacial oscillations. These current differences create unwanted voltage fluctuations and therefore power oscillations on the grid. The intensity is defined as the square of the amplitude of the oscillations. If the amplitude of the oscillations increases with time, the system is unstable. Some neurons also generate subthreshold membrane potential oscillations. Both conditions present with altered low-frequency brain wave oscillations. A well-known example of macroscopic neural oscillations is alpha activity. They play vital roles in reflexes, neuronal oscillations, and neurogenesis in the adult mammalian brain. Creating an ultra-fast diode capable of rectifying the high frequency oscillations. Quantitative models can estimate the strength of neural oscillations in recorded data. The quasiparticle resulting from the quantization of these oscillations is the plasmon. Another approach is to use nuclear transitions driven by collective electron oscillations. Introducing the resistor increases the decay of these oscillations, which is also known as damping.
