WebThe seismic reflection method usually gives better resolution (i.e., makes it possible to see smaller features) than other methods, with the exception of measurements made in close proximity, as with borehole logs (see below). Appreciably more funds are expended on seismic reflection work than on all other geophysical methods combined.

WebApr 12, 2024 · Download PDF Abstract: We present a deep learning method for accurately localizing the center of a single corneal reflection (CR) in an eye image. Unlike previous approaches, we use a convolutional neural network (CNN) that was trained solely using simulated data. Using only simulated data has the benefit of completely sidestepping the … WebThese methods are based on PPG waveforms analysis and depend on the reliability of the acquired signals. They are strictly dependent on the biomechanical model used to couple flow, volumes, and pressures through the correct evaluation of the viscoelastic characteristics of the vessels and related phenomena (e.g., pressure pulse reflection).
