Shear-wave velocity ( ) is an important parameter used for site characterization in geotechnical engineering. However, dispersion curve inversion is challenging for most inversion methods due to its high non-linearity and mix-determined trait. In order to overcome these problems, in this study, a joint inversion strategy is proposed based on the particle swarm optimization (PSO) algorithm. The ...

In this paper, first a great number of inverse problems which arise in instrumentation, in computer imaging systems and in computer vision are presented. Then a common general forward modeling for them is given and the corresponding inversion problem is presented. Then, after showing the inadequacy of the classical analytical and least square methods for these ill posed inverse problems, a Baye...

The purpose of this study was to conduct a microgenetic study of the development of the concept of inversion as it applies to multiplication and division inversion problems. The study was modelled on Siegler and Stern’s (1998) study in which Grade 2 participants solved addition and subtraction inversion problems (a + b b) for 6 weekly sessions. In session 7, modified inversion problems (b + a b...
