This paper describes an efficient and robust algorithm for computing a common refinement of two meshes modeling a common surface of arbitrary shape by overlaying them on top of each other. A common refinement is an important data structure for transferring data between meshes that have different topological structures. Our algorithm is optimal in time and space, with linear complexity.

Controlled Perturbation is a framework for perturbing geometric sets to make the processes that use them more robust for fixed-precision manipulation. We present a Controlled Perturbation scheme for sets of line segments in IR (CPLS, for short). CPLS iteratively perturbs the endpoints of the line segments to eliminate potential degeneracies that may cause round-off errors when using fixed-preci...

In this paper we describe some problems arising in practical implementation of algorithms from computational geometry. Going to robust algorithms needs to solve issues such as rounding errors and degeneracies. Most of the problems are closely related to the incompatibility between on one side algorithms designed for continuous data and on the other side the discrete nature of the data and the c...

Background: Assessment of AMH cut-off levels in serum and in follicle fluid (FF) for patients with (group 2, n=34) and without (group1, n= 96) endocrinological risk factors, such as ovarian hyperstimulation syndrome (OHSS) and polycystic ovary syndrome (PCOS), is clinically useful in optimising the treatment protocol. Materials and Methods: AMH was analysed in serum and FF of 130 infertile pati...

Background: Some authors detected significantly higher IL-18 levels in serum, peritoneal, and pleural fluids of patients with severe OHSS as compared with control groups and suggest a role of IL- 18 as a marker of OHSS. Lower levels of IL-18 have been found to characterize unexplained infertility. In this study, we analyzed the importance of IL-18 levels in serum and follicle fluid in response ...
