A multi-model process for managing project complexity
International audienceDevelopments of large software systems have to face an exponential increase in volume and complexity of the requisite knowledge, tighter time constraints and a continual growing number of stakeholders. Current solutions are based on breaking down the system or software components and equipments in smaller pieces in order to be able to handle them, but the side effect of this approach is to dilute the synthetic vision. This paper presents a model centric process supported by tools. This process is based on a multi-model approach for managing synthetic views and making project information available to all stakeholders, with an appropriate view and presentation

ROTATIONAL ANALYSIS OF THE NEAR INFRARED SINGLET-TRIPLET ELECTRONIC SPECTRUM OF OZONE
Author Institution: Laboratoire de Spectrom\'{e}trie lonique et Mol\'{e}culaire (associ\'{e} au CNRS U.M.R. 5579), Universit\'{e} Claude Bernard Lyon; Laboratoire de Chimie-Physique, Facult\'{e} des Sciences de Reims; Department of Chemistry, University of Wisconsin-ParksideHigh Resolution Fourier Transform Infrared Spectrometry was used to study the rotational fine structure of the lowest energy singlet-triplet electronic spectrum of ozone, and near . With a near pure case (b) coupling model, approximately 100 lines were assigned in the spectrum of . A combined least-squares/band contour analysis yielded an overall standard deviation of . The fit to the spectrum used approximately 30 lines and gave a slightly higher overall standard deviation. The rotational analysis has established that the upper state is in agreement with recent theoretical calculations. Numerous perturbations are observed in the spectrum of both isotopomers and limited our least-squares fit to the three rotational constants, the symmetric top distortion constants, the three spin-rotation constants and the alpha spin-spin constant. The talk will feature an overview of the rotational analysis along with a brief discussion of the perturbations seen in the spectrum
Concept and processing of buried photomasks
A new method for fabricating photomasks is proposed. The mask is prepared by burying the absorbent patterns inside the transparent photoplate instead of depositing them on the surface of the photoplate. After imaging and etching trenches into the glass substrate, an absorbent material is set into them. Two different ways of filling in these holes are considered : planarisation and lift-off. Various advantages of this technique are expected, namely high resolution. This paper presents results obtained by vacuum contact printing of positive and negative novolak based photoresists exposed through buried masks
Comparing zonal and CFD model predictions of isothermal indoor airflows to experimental data
Chemical synthesis and biological evaluation of triazole derivatives as inhibitors of InhA and antituberculosis agents.
A series of triazoles have been prepared and evaluated as inhibitors of InhA as well as inhibitors of Mycobacterium tuberculosis H(37)R(v). Several of these new compounds possess a good activity against InhA, particularly compounds 17 and 18 for which molecular docking has been performed. Concerning their activities against M. tuberculosis H(37)R(V) strain, two of them, 3 and 12, were found to be good inhibitors with MIC values of 0.50 and 0.25 μg/mL, respectively. Particularly, compound 12 presenting the best MIC value of all compounds tested (0.6 μM) is totally inactive against InhA
Fully Optimized Cu based process with dedicated cavity etch for 1.75m and 1.45m pixel pitch CMOS Image Sensors
International audienceAn innovative process development for sub-2μm CMOS imager sensors is described, leading to tremendous improvements on main pixel parameters like conversion gain, saturation charge, sensitivity, dark current and noise. A full 3MP demonstrator with 1.75μm pixel pitch and 1.45μm pixel pitch have been successfully designed, fabricated and characterized
