Aligning Key Success Factors to ERP Implementation Strategy: Learning from a Case Study

CAHIER DE RECHERCHE n°2012-08 E5These last years, we can observe that most of companies implemented an ERP system but many of them fail. Much of research that has been conducted in this field, focus on KSFs. We have noticed that confronting those KSFs to ERP implementation strategies seems quiet fecund. So provide in this article a brief overview of the literature dealing with key success factors related to an ERP implementation project to better cope with the field, then come out with a framework analyzing these KSFs depending on implementation strategies. Then we study a case of an ERP implementation project in a company operating in the automotive industry, with a quail-metric methodology, to better understand the reasons of ERP implementation projects success or failure

Monitoring and simulations of hydrolysis in epoxy matrix composites during hygrothermal aging

In this paper, we studied the water transport in thermoset matrices. We used Fourier Transform Infrared analysis (FTIR) during sorption/desorption experiments to investigate the interaction between sorbed water and the epoxy network. Our results demonstrated that the polymer matrix undergoes hydrolysis. We found that the chemical species involved in the reaction process was the residual anhydride groups. These results support the physical basis of the three-dimensional (3D) diffusion/reaction model. We finally showed that this model is able to reproduce multi-cycle sorption/desorption experiment, as well as water uptake in hybrid metal/epoxy samples. We simulated the 3D distributions of the diffusing water and the reacted water

SCSA based MATLAB pre-processing toolbox for 1H MR spectroscopic water suppression and denoising

In vivo 1H Magnetic Resonance Spectroscopy (MRS) is a useful tool in assessing neurological and metabolic disease, and to improve tumor treatment. Different pre-processing pipelines have been developed to obtain optimal results from the acquired data with sophisticated data fitting, peak suppression, and denoising protocols. We introduce a Semi-Classical Signal Analysis (SCSA) based Spectroscopy pre-processing toolbox for water suppression and data denoising, which allows researchers to perform water suppression using SCSA with phase correction and apodization filters and denoising of MRS data, and data fitting has been included as an additional feature, but it is not the main aim of the work. The fitting module can be passed on to other software. The toolbox is easy to install and to use: 1) import water unsuppressed MRS data acquired in Siemens, Philips and .mat file format and allow visualization of spectroscopy data, 2) allow pre-processing of single voxel and multi-voxel spectra, 3) perform water suppression and denoising using SCSA, 4) incorporate iterative nonlinear least squares fitting as an extra feature. This article provides information about how the above features have been included, along with details of the graphical user interface using these features in MATLAB

Using different spatial scale measurements in a geostatistically based approach for mapping atmospheric nitrogen dioxide concentrations. Application to the French Centre region

International audiencePassive sampling surveys followed by geostatistical data analysis have become a common and efficient way of mapping background concentrations at regional and urban scale. Traffic related pollution is also a matter of concern as regards people exposure but since it acts at shorter spatiotemporal scales, it is usually not integrated in the same maps. However, to provide more comprehensive information to the authorities and the public, the organisms responsible for air quality monitoring are searching for innovative ways of representing background and roadside concentrations together. A methodology based on geostatistics and the examination of the relationships between season averaged nitrogen dioxide concentrations and auxiliary variables is proposed in this study. It is applied to data collected in the French Centre region

Structural characteristics of simply connected planar sections with application to airfoils

The presented work is to develop a numerical computation program to determine the geometrical characteristics of arbitrary simply connected planar sections and applications to airfoils. In the literature, there are exact analytical solutions only for some simples’ geometries, such as circular, rectangular and elliptical sections. Hence our interest is focused on the search of approximate numerical solutions for more complex sections used in aeronautics. The used method is to subdivide the section in the infinitesimal triangular sections with a single observer within the area having a suitable position. The characteristics of any triangle, given by the positions of these three nodes are known in the literature. Using the principle of compound surfaces, one can determine the geometric characteristics of the airfoil surface. The analytic function of the airfoil boundary is obtained by using the cubic spline interpolation because the airfoil is given in the form of tabulated points. Error estimation is done to determine the accuracy of the numerical computation

Nouveaux modes de lecture-écriture des enseignants chercheurs tunisiens dans l'environnement numérique

We present in this paper the partial results of a survey of faculty Tunisians on their new practices of reading and writing and new forms of appropriation or exchange content in a digital environment emerged. OF RESULTS These are a set of answers to questions related to the types of digital documents most read, the structuring elements most useful to document formats most used and most popular, as well as the representation of hyperlinks in teacher-researchers. Other elements of answers related to collaborative work practices Tunisian researchers such as annotations of documents and participation in online group work are also presented

Lecture numérique : impact du genre et de la discipline scientifique sur l'usage du web 2 .0

A nos jours, l'acte de lire, qui représente " l'activité par laquelle se comprend l'écrit " [Foucambert, 96], se trouve complètement transformé. Impliquant toute sorte d'activité cognitive, dépendant du niveau des connaissances du lecteur [Gastaldy, 02] et du support, à partir duquel elle s'effectue [Vandendorpe, 01], et faisant appel à trois dimensions : sémiotique, psycho-cognitive et sociale [Peeters et Charlier, 95], la lecture à l'ère du numérique connait une véritable révolution. Evoquer le verbe lire, c'est parler du déchiffrement, de la navigation, de l'interprétation, de l'appropriation, du partage, etc [Ghitalla, 03]. Dans le contexte tunisien, outre ces amalgames de concepts, la réalité sociale et culturelle nous offre un nouveau paysage de cet acte de lecture chez les chercheurs tunisiens à l'ère de l'omniprésence de l'ordinateur. Nous étudions l'influence de la variable genre sur les pratiques et les usages du numériques chez 307 chercheurs tunisiens et nous croisons cette variable avec la catégorie du chercheur puis avec sa discipline scientifique d'appartenance. Littéraires et scientifiques changent d'habitudes vis-à-vis de l'activité de lecture ; hommes et femmes n'ont pas le même rapport avec les outils numériques (l'activité de lecture est-elle une activité masculine !) ; " Natifs du numérique " (digital natives) et leurs aînés n'ont pas le même rapport à la culture et n'ont pas les mêmes références culturelles [Giffard, 09], [Octobre, 10] ; et enfin, le travail collaboratif imposé aujourd'hui par ces nouveaux outils numériques concrétisant le processus social de la lecture reste encore timide (absence d'une culture de groupe chez les chercheurs tunisiens à l'ère de facebook !). Les femmes transposent plus que les hommes leurs pratiques de lecture sur papier quand elles sont intéressées par un document numérique. Plus que les hommes, elles préfèrent imprimer le document numérique que le consulter sur l'écran et elles ont tendance à prendre des notes sur papier en cas de lecture numérique. Femmes et hommes utilisent dans leur majorité les fonctionnalités offertes par le web 2.0. Des résultats montrent néanmoins des usages spécifiques à tel ou tel autre genre pour certaines fonctionnalités. Les femmes sont légèrement moins portées que les hommes pour l'échange et le partage de documents. Aussi, elles participent moins que les hommes à des communautés scientifiques virtuelles. D'ailleurs, l'accès aux ressources numériques a plus d'impact sur la culture d'hommes que des femmes. Les éléments de réponse et les idées avancées dans cette communication trouvent leurs fondements dans une enquête menée par le groupe " lecture des documents numériques et nouveaux usages " en 2008 auprès des chercheurs tunisiens portant sur leurs pratiques de lecture numérique [Limam, 08], [Ben Romdhane, 08], [Hchicha, 09], mais aussi par un brassage d'une littérature assez riche et diversifiée sur l'activité de lecture. Cette analyse des pratiques de lecture chez les chercheurs tunisiens et des différents éléments affectant ces pratiques sera confrontée à des résultats de travaux de recherche développés chez nos voisins du nord [Donnat, 09], [Béreau, 09], [Stiegler, 09], [Ziming, 06]
