Texte intégralMolecular engineering is based on the knowledge of the stereoelectronic features that define the molecular recognition, which is the result of the complementarity of geometric and electronic features between two different molecular entities. The importance of different electrostatic contributions allows us to make a theoretical prediction of molecular properties, from calculations of electrostatic potential and molecular polarization. This work is based on the study of the use of maps of electrostatic potential and polarization potential as molecular descriptors. First there is a study of the effect of the basis set and the methodology used in the calculation of first and second order electrical properties. The analysis was carried out with the molecules of hydrogen cyanide, formaldehyde and urea. The base sets used are the standard double-zeta, to which were added polarization and diffuse functions. In particular, we have used the double zeta basis 6-31G (d), double zeta basis augmented with one or two sets of polarization functions: 6-31G (d, p), 6-31G (2d, 2p) and also used the base 6-311G + + (2d, 2p), which includes diffuse functions. The different levels of calculation methodologies used Hartree-Fock, Moller-Plesset second and fourth order and the theory of density functional (DFT): SCF, MP2, MP4, BLYP B3LYP i. We analyze the effect of different sets based on the contribution of polarization to the interaction energy, calculated for each system of first order properties, such as dipolar moments and quadrupolar moments, and second order properties such as polarizability and molecular hyperpolarizability. Further, the effect of the basis and method on the calculation of the electrostatic potential and molecular polarization potentials is evaluated. For this purpose we performed a comparative study of the maps calculated with different basis sets and methodologies, in particular a study of the spatial distribution and correlation analysis between the different data bases and methodologies was done. An analysis of molecular polarization maps by calculating the differences in polarization and relative standard deviation allows for a comparative study of different methodologies and bases used. Specifically, a comparative analysis between different methods of calculating the base 6-311G + + (2d, 2p), calculated by reference to the MP4 was done. We use maps of electrostatic, polarization and interaction potentials for the analysis of molecular recognition features of a set of bioactive compounds, to discuss the importance of the contribution of polarization. For this reason, we choose to study a set of molecules with high polarizability, specifically, two families of compounds with heavy atoms of chlorine and defined toxic activity, which are part of groups of dioxins and furans. A study of the polarization maps as indicators of biological activity of dioxins and furans, based on the best methodology is done. The inclusion of polarization as a molecular descriptor for predicting biological activity of dioxins and furans was studied from the calculation of electrostatic potentials and polarization, an analysis of the potential maps, and defining the main areas of interaction molecular electrostatic and polarization interaction from calculations of principal components (PCA) and the prediction of biological activity based on a study by calculation of partial least squares (PLS).

Texte intégralThis thesis focus on developping a fault detection methodology for semiconductor manufacturing equipment. The proposed approach is based on Principal Components Analysis (PCA) to build a representative model of equipment in adequat operating conditions. Our method exploits collected measurements from equipement sensors, for each processed wafer. However, regarding the industrial context and processes, we have to consider additional problems: collected signals from sensors exhibit different length, or durations. This is a limitation considering PCA. We have also to consider synchronization and alignment problems; semiconductor manufacturing equipment are almost dynamic, with strong temporal correlations between sensor measurements all along processes. To solve the first point, we developped a data preprocessing module to transform raw data from sensors into a convenient dataset for PCA application. The interest is to identify outliers data and products, that can affect PCA modelling. This step is based on expert knowledge, statistical analysis, and Dynamic Time Warping, a well-known algorithm from signal processing. To solve the second point, we propose a combination multiway PCA with the use of an EWMA filter to consider process dynamic. A recursive approach is employed to adapt our PCA model to specific events that can occur on equipment, e.g. maintenance, restart, etc.All the steps of our methodology are illustrated with data from a chemical vapor deposition tool exploited in STMicroelectroics Rousset fab. Finally, the efficiency and industrial interest of the proposed methodologies are verified by considering multiple equipment types on longer operating periods

Texte intégralThe solid-liquid adsorption of PCBs and DDT is an effective process for the recuperation of wastewaters but a better understanding of the involved mechanism is required. In this study, the static adsorption kinetics were mainly carried out at 25 ° C for 2-PCB, a mixture of tetra-, penta-and hexa-CB, and 4,4 '-DDT onto three different powdered activated carbons (AC) of the precursor (coal, wood) and the activation mode (H2O, H3PO4) in water, with or without ethanol. The prominent results were as follows: The adsorption of the pollutant on the AC is favored if its solubility in the liquid phase is lower. As a result, the adsorption of the hydrophobic pollutant is significantly increased in pure water. Moreover, the adsorption of pollutants favored by the developed microporosity is a surface phenomenon which involved the Van der Waals forces. A good fit between the size of molecules and the average width of the slit-shape pores gave a maximum confinement of molecules in the micropores. The π−π interaction between adsorbate and adsorbent, favored by the number of Cl, is not excluded. Finally, by studying the kinetics of the initial conditions, we found that the adsorption is limited by the external mass transfer. The internal surface diffusion coefficients estimated from applying the homogeneous surface diffusion models (HSDM) showed that the adsorption kinetics are almost completely governed by the intra-particle diffusion
