Calculations of Gravitational Waves from Binary Black Hole Systems

A deliberately classical model of a black-hole inspiral: Newtonian circular orbits losing energy at the Peters–Mathews rate, integrated until the event horizons meet, and the resulting frequency sweep compared with LIGO's observations.

Study on Power Spectral Density by Improving Electroencephalography Signal Quality

Area of the alpha band in EEG as a measure of stability

Measuring the area under the alpha band of an EEG spectrum as a quantitative index of restfulness, with an autoencoder trained to denoise the signal before the spectrum is taken.
