| 31. | Such a time series does not have a strict periodicity, but its power spectrum still consists only of sharp lines.
|
| 32. | Ambient radiation heats dust and re-emits radiation into the microwave band, which may distort the cosmic microwave background power spectrum.
|
| 33. | The result was an improved power spectrum of the CMB, going out to a multipole of 1400, and refined cosmological parameters.
|
| 34. | Another complication is that the BAO feature in the power spectrum is affected by non-linear evolution of the matter density field.
|
| 35. | The power spectrum, as indicated by this density function, measures the amount of variance contributed to the data by the frequency.
|
| 36. | As the trail dissipates, megawatts of electromagnetic power could be released, with a peak in the power spectrum at audio frequencies.
|
| 37. | In the far-infrared the CIB power spectrum can be effectively used to separate it from its strongest foreground, the Galactic cirrus emission.
|
| 38. | For example, if the underlying data is some form of power spectrum then there are well-defined rules about the expected peak separation.
|
| 39. | James Keeler and Farmer demonstrated that a system of coupled logistic maps could produce fluctuations with a 1 / f power spectrum.
|
| 40. | Primordial fluctuations are typically quantified by a power spectrum which gives the power of the variations as a function of spatial scale.
