We study the linear $(\alpha^{(1)} )$, nonlinear $(\alpha^{(3)})$ and total $(\alpha)$ optical absorptions of position-dependent mass oscillators (PDMOs). We consider three mass distributions $(m(x,\lambda))$ used to describe semiconducting structures; $\lambda$ is a deformation parameter. In the limit $\lambda\rightarrow 0$, the three systems describe electrons in a parabolic quantum well. For the system $m_1(x)=m_0/[1+(\lambda x)^2 ]^2$ we observe that $\alpha^{(1)}(\omega)) (\alpha^{(3… Expand

Many graphics and vision problems can be expressed as non-linear least squares optimizations of objective functions over visual data, such as images and meshes. The mathematical descriptions of these… Expand
