The reliability of analytical results obtained with quantitative analytical methods is highly dependant upon the selection of the adequate model used as calibration curve. To select the adequate response function or model the most used and known parameter is the determination coefficient R². However it is well known that it suffers many inconvenient, such as leading to overfitting the data. A solution proposed is to use the adjusted determination coefficient R²adj that aims at reducing this problem. However there is another family of criteria that exists to allow the selection of an adequate model: the information criteria AIC, AICc and BIC. These criteria have rarely been used in analytical chemistry to select the adequate calibration curve. This works aims at assessing the performance of the statistical information criteria as well as R² and R²adj for the selection of an adequate calibration curve. They are applied to several analytical methods covering liquid chromatographic methods as well as electrophoretic ones involved in the analysis of active substances in biological fluids or aimed at quantifying impurities in drug substances. In addition, Monte-Carlo simulations are performed to assess the efficacy of these statistical criteria to select the adequate calibration curve. [less ▲]

Laboratory studies were conducted to validate the effectiveness of the use of high-speed imaging method to replace chemical nalysis by fluoremetrie. Measurements were performed with a high-speed camera coupled with a retro-LED lighting. Size and velocity of the drop were extracted by image analysis. Drop impact types were determined by the operator. Drops were produced with a flat-fan nozzle mounted on a movable ramp. Two surfactants (Break-Thru® S240 and Li700 ®) were sprayed on BBCH 12 barley leaves to highlight the effect of the reduction of surface tension. Relative volume proportions were computed within of an energy scale divided into 11 classes based on the Weber number. results are compared to the results of the chemical analysis by spectrofluerometry.

This paper investigates the stakes of introducing probabilistic approaches for the management of power system’s security. In real-time operation, the aim is to arbitrate in a rational way between preventive and corrective control, while taking into account i) the prior probabilities of contingencies, ii) the possible failure modes of corrective control actions, iii) the socio-economic consequences of service interruptions. This work is a first step towards the construction of a globally coherent decision making framework for security management from long-term system expansion, via mid-term asset management, towards short-term operation planning and real-time operation.
