Smart city projects and improvement of public service supply chains

International audienceThe involvement in smart city initiatives is a key factor of changes in modern cities. It drives the integration of ICT, the development of collaborative behaviours, and the involvement of people in the life of the city. This paper is interested in the impact of such initiatives on the performance of public services and on the supply chains that provide these services. Based on the example of the Toulouse metropolis in France, it shows that smart city initiatives are becoming a vector for instilling continuous improvement in public services

Méthodes et outils de la performance industrielle au service de la fonction publique

La transposition de méthodes d'amélioration des performances industrielles au secteur tertiaire est une démarche entreprise depuis plus d’une trentaine d’année, avec des cibles incluant des entités appartenant à la fonction publique. Cette démarche est cohérente avec des méthodes et réformes cadrant ce secteur d'activité, telles que la NMP (Nouveau Management Public) et la LOLF (Loi Organique relative aux Lois de Finances). Ces pratiques ont été à l'origine d'améliorations dans des domaines transversaux, comme le pilotage de la chaîne logistique du secteur et l'amélioration de la chaîne de valeur, mais restent marginales. L'utilisation de ces méthodes, souvent perçues comme entrainant une diminution du service à l'usager, reste en effet très controversée au sein du secteur public. Cette communication a pour but de mettre en avant l'intérêt que peut avoir le secteur public à s’inspirer des méthodes "industrielles", ainsi que la nécessité de les redéfinir pour qu’elles deviennent pleinement applicables à la fonction publique

First Detection of Polarization of the Submillimetre Diffuse Galactic Dust Emission by Archeops

We present the first determination of the Galactic polarized emission at 353 GHz by Archeops. The data were taken during the Arctic night of February 7, 2002 after the balloon--borne instrument was launched by CNES from the Swedish Esrange base near Kiruna. In addition to the 143 GHz and 217 GHz frequency bands dedicated to CMB studies, Archeops had one 545 GHz and six 353 GHz bolometers mounted in three polarization sensitive pairs that were used for Galactic foreground studies. We present maps of the I, Q, U Stokes parameters over 17% of the sky and with a 13 arcmin resolution at 353 GHz (850 microns). They show a significant Galactic large scale polarized emission coherent on the longitude ranges [100, 120] and [180, 200] deg. with a degree of polarization at the level of 4-5%, in agreement with expectations from starlight polarization measurements. Some regions in the Galactic plane (Gem OB1, Cassiopeia) show an even stronger degree of polarization in the range 10-20%. Those findings provide strong evidence for a powerful grain alignment mechanism throughout the interstellar medium and a coherent magnetic field coplanar to the Galactic plane. This magnetic field pervades even some dense clouds. Extrapolated to high Galactic latitude, these results indicate that interstellar dust polarized emission is the major foreground for PLANCK-HFI CMB polarization measurement.Comment: Submitted to Astron. & Astrophys., 14 pages, 12 Fig., 2 Table

Temperature and polarization angular power spectra of Galactic dust radiation at 353 GHz as measured by Archeops

We present the first measurement of temperature and polarization angular power spectra of the diffuse emission of Galactic dust at 353 GHz as seen by Archeops on 20% of the sky. The temperature angular power spectrum is compatible with that provided by the extrapolation to 353 GHz of IRAS and DIRBE maps using \cite{fds} model number 8. For Galactic latitudes $|b| \geq 5$ deg we report a 4 sigma detection of large scale ($3\leq \ell \leq 8$) temperature-polarization cross-correlation $(\ell+1)C_\ell^{TE}/2\pi = 76\pm 21 \mu\rm{K_{RJ}}^2$ and set upper limits to the $E$ and $B$ modes at $11 \mu\rm{K_{RJ}}^2$. For Galactic latitudes $|b| \geq 10$ deg, on the same angular scales, we report a 2 sigma detection of temperature-polarization cross-correlation $(\ell+1)C_\ell^{TE}/2\pi = 24\pm 13 \mu\rm{K_{RJ}}^2$. These results are then extrapolated to 100 GHz to estimate the contamination in CMB measurements by polarized diffuse Galactic dust emission. The $TE$ signal is then $1.7\pm0.5$ and $0.5\pm0.3 \mu\rm{K^2_{CMB}}$ for $|b| \geq 5$ and 10 deg. respectively. The upper limit on $E$ and $B$ becomes $0.2 \mu\rm{K^2_{CMB}} (2\sigma)$. If polarized dust emission at higher Galactic latitude cuts is similar to the one we report here, then dust polarized radiation will be a major foreground for determining the polarization power spectra of the CMB at high frequencies above 100 GHz.Comment: 11 pages, 8 figures, submitted to A

The Cosmic Microwave Background Anisotropy Power Spectrum measured by Archeops

We present a determination by the Archeops experiment of the angular power spectrum of the cosmic microwave background anisotropy in 16 bins over the multipole range l=15-350. Archeops was conceived as a precursor of the Planck HFI instrument by using the same optical design and the same technology for the detectors and their cooling. Archeops is a balloon-borne instrument consisting of a 1.5 m aperture diameter telescope and an array of 21 photometers maintained at ~100 mK that are operating in 4 frequency bands centered at 143, 217, 353 and 545 GHz. The data were taken during the Arctic night of February 7, 2002 after the instrument was launched by CNES from Esrange base (Sweden). The entire data cover ~ 30% of the sky.This first analysis was obtained with a small subset of the dataset using the most sensitive photometer in each CMB band (143 and 217 GHz) and 12.6% of the sky at galactic latitudes above 30 degrees where the foreground contamination is measured to be negligible. The large sky coverage and medium resolution (better than 15 arcminutes) provide for the first time a high signal-to-noise ratio determination of the power spectrum over angular scales that include both the first acoustic peak and scales probed by COBE/DMR. With a binning of Delta(l)=7 to 25 the error bars are dominated by sample variance for l below 200. A companion paper details the cosmological implications.Comment: A&A Letter, in press, 6 pages, 4 figures, see also http://www.archeops.or

Archeops: A High Resolution Large Sky Balloon Experiment for Mapping CMB Anisotropies

Archeops is a balloon-borne instrument dedicated to measuring cosmic microwave background (CMB) temperature anisotropies at high angular resolution (8 arcminutes) over a large fraction (25%) of the sky in the millimetre domain. Based on Planck High Frequency Instrument (HFI) technology, cooled bolometers (0.1 K) scan the sky in total power mode with large circles at constant elevation. During the course of a 24-hour Arctic-night balloon flight, Archeops will observe a complete annulus on the sky in four frequency bands centered at 143, 217, 353 and 545 GHz with an expected sensitivity to CMB fluctuations of \~100muK for each of the 90 thousand 20 arcminute average pixels. We describe the instrument and its performance obtained during a test flight from Trapani (Sicily) to Spain in July 1999

Smart City approach as a new framework for the integration of industrial engineering methods in the public sector supply chain

Le secteur public est un domaine en perpétuelle mutation, de par la pression économique actuelle mais aussi du fait des progrès technologiques constants. C'est en particulier le cas des collectivités territoriales, dans lesquelles les agents du secteur public sont soumis à de fortes pressions, notamment par la nécessité d'assurer un service de qualité aux usagers tout en minimisant les coûts engagés, mais également du fait de devoir développer de nouvelles compétences pour répondre à des exigences en évolution. Les projets actuels, impliquant de multiples technologies et le besoin de travailler en synergie avec les acteurs territoriaux, sont devenus primordiaux pour la gestion des chaînes logistiques du secteur public. Le domaine du génie industriel a développé diverses méthodes pouvant répondre à ces nouveaux besoins. Ces méthodes englobent différentes théories et pratiques allant du progrès permanent à la gestion de la chaîne logistique jusqu’à la gestion de la relation client. Ces pratiques visent avant tout à améliorer la coordination et l'intégration de toutes les activités nécessaires à l'élaboration d’un produit ou un service. L’apparition de nouvelles démarches, telles que la Smart City, légitime la mise en pratique de méthodes industrielles pour la gestion de services répondant à l’intérêt général d’un territoire. Dès lors, l'objectif de ce travail a été de transposer aux collectivités territoriales des méthodes issues du génie industriel, en s’appuyant sur la démarche de la Smart City, afin de permettre une synergie entre les partenaires, tout en augmentant la productivité de l’organisation dans la fourniture de services publics plus performants.The public sector is a domain in perpetual transformation, due to current economic pressure and constant technological progress. This is particularly the case in Urban Communities, where employees are under intense pressure, notably by the need to ensure services of high quality to their users while minimizing the costs incurred, but also because of the necessity to develop new skills to meet the new requirements of the sector. Current projects involving multiple technologies, the need to work in synergy with the territorial actors becomes essential for the management of the public sector supply chains. The field of industrial engineering has developed various methods which can address these new needs for the public sector. These methods include various theories and practices going from continuous improvement to Supply Chain Management, including customer relationship management. These practices aim above all at improving the coordination and integration of all activities necessary to the development of a product or service. The emergence of new approaches, such as the Smart City, legitimizes the application of industrial methods for the management of services answering the general interest of a territory. Consequently, the objective of this work is to adapt to the Urban Communities of the methods derived defined in industrial engineering and to integrate the approach of Smart City to improve the synergy between the partners, while increasing the productivity of the organization in the supply of more efficient public services

Proposition d'une modélisation pour l'amélioration des performances du secteur public

Le congrès a pour titre "L'essor des systèmes connectés dans l'industrie et les services"International audienceLe secteur public, comme toute organisation, cherche à améliorer sa performance tout en conservant ou améliorant le service rendu aux usagers et citoyens. Dans une logique d’amélioration continue, les méthodes existantes issues du progrès permanent dans l’industrie peuvent être adaptées afin d’intégrer les spécificités du secteur public. Cet article présente un cadre de modélisation pour les services publics incluant lamesure de performance et l’intégration d’actions d’amélioration dans un souci d’agilité. Il montre la nécessité d’intégrer les composantes de cet environnement afin de développer des modèles de référence utiles à la modélisation globale. La cohérence de ces modèles est présentée sur un cas d’étude basé sur l’expérimentation d’une application visant, entre autres, à informer les usagers des menus proposés dans les cantines scolaires approvisionnées par la cuisine centrale de Toulouse Métropole

Contrasted microcolinearity and gene evolution within a homoeologous region of wheat and barley species

UMR DIAPC, UMR DAP équipe DGBWe study here the evolution of genes located in the same physical locus using the recently sequenced Ha locus in seven wheat genomes in diploid, tetraploid, and hexaploid species and compared them with barley and rice orthologous regions. We investigated both the conservation of microcolinearity and the molecular evolution of genes, including coding and noncoding sequences. Microcolinearity is restricted to two groups of genes (Unknown gene-2, VAMP, BGGP, Gsp-1, and Unknown gene-8 surrounded by several copies of ATPase), almost conserved in rice and barley, but in a different relative position. Highly conserved genes between wheat and rice run along with genes harboring different copy numbers and highly variable sequences between close wheat genomes. The coding sequence evolution appeared to be submitted to heterogeneous selective pressure and intronic sequences analysis revealed that the molecular clock hypothesis is violated in most case
