Synthetics and Theoretical Seismology
range and the location of artificial reflectors or intermediate values at these points. A similar fictitious sources inherent in discrete wave economy can be obtained using the itrerative reflection and transmission coefficient relations number techniques. The number and spacing of wave numbers in wave number integration schemes are of Kennett. Kamel and Felsen (1981) presented a hybrid determi...
متن کاملSynthetics and Simulants
identified the gem as glass, but the nature of the strange veins containing tiny trapped gas bubbles remained a mystery. Fourier-transform infrared (FTIR) spectroscopy was performed next, but no polymers were detected. The RI was recorded as 1.52, and we concluded that this gem consisted of a solid piece of green lead glass. Viewed with the microscope, an experienced eye might sense that there ...
متن کاملApproximate 3 D Body - Wave Synthetics for Tomographic Models
We present a new method of generating analytical synthetics for tomographic-style models. These models are perturbations to a 1D layered model involving changes in block velocities producing 3D images. The procedure is broken into three steps: (1) construction of ray paths for the reference 1D layered model, (2) generation of perturbed paths and the construction of 2D synthetics in the plane co...
