A semi-automated computer tool for the analysis of retinal vessel diameter dynamics.

Retinal vessels are directly accessible to clinical observation. This has numerous potential interests for medical investigations. Using the Retinal Vessel Analyzer, a dedicated eye fundus camera enabling dynamic, video-rate recording of micrometric changes of the diameter of retinal vessels, we developed a semi-automated computer tool that extracts the heart beat rate and pulse amplitude values from the records.

Impact of the probe solutes set on orthogonality evaluation in reverse phase chromatographic systems.

Two-dimensional liquid chromatography (2DLC) is a very attractive technique for the characterization of complex samples due to its separation power obtained via the coupling of two separation modes exhibiting different mechanisms, i.e. orthogonality.

Comparison of different statistical approaches to evaluate the orthogonality of chromatographic separations: application to reverse phase systems.

Selectivity of phase system is of primary concern when designing a bidimensional chromatographic system and looking for the highest degree of orthogonality between the two separations. Several statistical or geometrical criteria can potentially be used to measure the degree of orthogonality. A comparison of eight candidate criteria has been carried out in this study.

Linear regression models and neural networks for the fast emulation of a molecular absorption code.

The background scene generator MATISSE, whose main functionality is to generate natural background radiance images, makes use of the so-called Correlated K (CK) model. It necessitates either loading or computing thousands of CK coefficients for each atmospheric profile. When the CK coefficients cannot be loaded, the computation time becomes prohibitive.
