Timing of emergency IUD fitting.
We wish to thank Dr Davies for raising an issue we were not able to address in our original letter due to space limitations. The issue with emergency contraception intrauterine devices (EC IUDs) is slightly different. An EC IUD has to be fitted prior to implantation. This is a process that starts no sooner than 6 days after fertilisation, and fertilisation cannot happen prior to sexual intercou...

a study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
Curve Fitting by Fractal Interpolation
Fractal interpolation provides an efficient way to describe data that have an irregular or self-similar structure. Fractal interpolation literature focuses mainly on functions, i.e. on data points linearly ordered with respect to their abscissa. In practice, however, it is often useful to model curves as well as functions using fractal intepolation techniques. After reviewing existing methods f...
متن کاملConstrained curve fitting on manifolds
When designing curves on surfaces the need arises to approximate a given noisy target shape by a smooth fitting shape. We discuss the problem of fitting a B-spline curve to a point cloud by squared distance minimization in the case that both, the point cloud and the fitting curve, are constrained to lie on a smooth manifold. The on-manifold constraint is included by using the first fundamental ...
