The I-MOVE\ Consortium includes European Union (EU) Public Health Institutes, SME and Universities. It aims at measuring and comparing the effectiveness (VE) and impact (VI) of influenza and Pneumococcal vaccines and vaccination strategies a in the elderly population in Europe. The goal is to develop a sustainable platform of primary care practices, hospitals and laboratory networks that share validated methods to evaluate post marketing vaccine performances. The objectives are to identify, pilot test, and disseminate in EU the best study designs to measure, on a real time basis, VE (direct effect) and the VI of vaccination programmes (indirect and overall effect) against laboratory confirmed cases of influenza (types/subtypes) and pneumococcal disease (serotypes), and clinical outcomes. Cost effectiveness analysis will be conducted. Results will allow to understand factors affecting specific VE, the duration of protection of influenza and pneumococcal vaccines, the interaction between vaccines, the role of repeated vaccinations, the occurrence of serotype replacement (pneumococcus); identify vaccine types and brands with low VE; guide the decision of the WHO committees on vaccine strain selection (influenza); provide robust benefit indicators (VE and VI) and cost benefit and effectiveness results; guide vaccination strategies (schedules, doses, boosters). This EU member state collaboration will respond to questions that require studies based on large sample sizes and sharing of expertise that cannot be achieved by one country alone. It will allow the best methods to be used and results to benefit to all EU countries whatever their current public health achievements. Results will be shared with international partners.

Forest fires release significant amounts of trace gases and aerosols into the atmosphere. Depending on meteorological conditions, fire emissions can efficiently reduce air quality and visibility, even far away from emission sources. In 2005, an arson forest fire burned nearly 700 ha near Lançon-de-Provence, southeast France. This paper explores the impact of this Mediterranean fire on the atmospheric dynamics and chemistry downwind of the burning region. The fire smoke plume was observed by the MODIS-AQUA instrument several kilometres downwind of the burning area out of the Mediterranean coast. Signatures of the fire plume on air pollutants were measured at surface stations in southeastern France by the air quality network AtmoPACA. Ground-based measurements revealed unusually high concentrations of aerosols and a well marked depletion of ozone concentrations on the day of the fire. The Lançon-de-Provence fire propagation was successfully simulated by the semi-physical fire spread model ForeFire. ForeFire provided the burnt area at high temporal and spatial resolutions. The burnt areas were scaled to compute the fire heat and water vapour fluxes in the three-dimensional meso-scale non-hydrostatic meteorological model MesoNH. The simulated fire plume kept confined in the boundary layer with high values of turbulent kinetic energy. The plume was advected several kilometres downwind of the ignition area by the Mistral winds in accordance with the MODIS and AtmoPACA observations. The vertical plume development was found to be more sensitive to the sensible heat flux than to the fire released moisture. The burnt area information is also used to compute emissions of a fire aerosol-like tracer and gaseous pollutants, using emission factors for Mediterranean vegetation. The coupled model simulated high concentrations of the fire aerosol-like tracer downwind of the burning zone at the right timing compared to ground-based measurements. A chemical reaction mechanism was coupled on-line to the MesoNH model to account for gaseous chemistry evolution in the fire plume. High levels of ozone precursors (NO x, CO) were simulated in the smoke plume which led to the depletion of ozone levels above and downwind of the burning zone. This depletion of ozone was indeed observed at ground-based stations but with a higher impact than simulated. The difference may be explained by the simplified design of the model with no anthropogenic sources and no interaction of the smoke aerosols with the photolysis rates. Ozone production was modelled tens of kilometres downwind of the ignition zone out of the coast. © 2012 Elsevier Ltd.

TILOS aims to demonstrate the optimal integration of local scale energy storage in a fully-operated, smart island microgrid that will also communicate with a main electricity grid. The main objective of the project will be the development and operation of a prototype battery storage system, based on NaNiCl2 batteries, provided with an optimum, real-environment smart grid control system and coping with the challenge of supporting multiple tasks, ranging from microgrid energy management, maximization of RES penetration and grid stability, to export of guaranteed energy amounts and provision of ancillary services to the main grid. The battery system will support both stand-alone and grid-connected operation, while proving its interoperability with the rest of microgrid components, including demand side management aspects and distributed, residential heat storage in the form of domestic hot water. At the same time, TILOS project addresses the high-priority area of the specific call concerning island regions. In doing so, apart from Tilos island, TILOS also engages the islands of Pellworm, La Graciosa and Corsica, aiming to create an island platform that will enable transfer of technological experience by making use of the smart grid system of Pellworm on the one hand, and by offering new case studies for the development of similar projects on the other. Elaboration of new case studies will be enabled by the development of an advanced microgrid simulating tool, i.e. the Extended Microgrid Simulator, offering the potential for the detailed examination of different battery technologies and microgrid configurations (stand-alone, grid connected and power market-dependent systems). Finally, by also addressing social issues, through public engagement, and by developing novel business models and policy instruments, TILOS puts emphasis on the market diffusion of the developed battery storage system and the integrated energy solution implemented on the island of Tilos.

The objective of this paper is to show that a precise study of renewable energy potential is indispensable before implementing a renewable energy system. The solar and wind energy potential is first presented for five sites distributed in a Mediterranean island and the temporal complementarity of these two energy resources is discussed. From this study, two meteorological sites are chosen and we compare the sizing and the profitability of remote hybrid PV/Wind systems for these two special cases study. © 2010 Published by Elsevier Ltd.

In this paper, we introduce new technique for localization of narrowband signals. We propose two new versions of the propagator method. Using its algebraic properties, the cross-spectral matrix (CSM) is replaced by the upper triangular matrix (UTM) obtained from the LU or QR factorization of the CSM. The upper triangular matrices are partitioned to estimate the propagator. The LU factorization and Householder QR factorization algorithms need N 3/3 and 2N 3/3 floating point operations, respectively. The triangular factorization technique can reduce the complexity when compared to eigen subspace method such as MUSIC algorithm requires N 3. Simulation results are presented to verify the effectiveness of the proposed methods. © 2012 IEEE.

An optimal sizing methodology based on an energy approach is described and applied to grid-connected photovoltaic systems taking into account the photovoltaic module technology and inclination, the inverter type and the location. A model describing the efficiency for m-Si, p-Si, a-Si and CIS is used. The method has been applied on various meteorological stations in Bulgaria and Corsica (France). The main parameter affecting the sizing is the inverter efficiency curve. The influence of the PV module technology seems less important except for amorphous photovoltaic modules for which special remarks have been made. The inclination on the PV system influences the performances particularly when the inverter is undersized compared to the PV peak power. © 2009 Elsevier Ltd. All rights reserved.

Energy Policy | Year: 2011

Corsica island has been subjected to an unprecedented abundance of photovoltaic plant projects since its energy policy is focused on renewable resources. Concerned public institutions require specific tools to select the most relevant projects among numerous projects proposed in a transparent and prudent way.To this end, a multicriteria decision aiding method was developed to select among 16 projects that have been proposed on farming fields in Haute Corse. This paper details the main stages in the multicriteria methodology, including criteria and constraint definition, criteria weight set calculations, threshold and concordance level determination and the implementation of the chosen multicriteria model, ELECTRE IS. Thus, considering different points of view (energy, geo-economic, ecological, visual impact, territorial use, financial effect), eight criteria have been defined, one of which is optional. The method applied to the reviewed data allowed building 6 weight sets, while a concordance level of 2/3. Using this method, based on our criteria sets and according to the weights and concordance levels determined by the client, 4 projects were selected among the 16 initial ones, with the robustness of these results being tested through all criteria weight sets and different concordance level applications. © 2010 Elsevier Ltd.

The paper describes new techniques to determine the number of sources for a signal based on LU and QR decomposition. We propose novel methods to calculate the threshold for noise subspace estimation used in high resolution array processing methods without eigenvalue decomposition. The paper states that previous techniques primarily use eigenvectors and eigenvalues. We propose an approximation of MUSIC algorithm. This approximation decreases the computational complexity. A full mathematical evaluation of the technique is provided and simulations show that the approach is effective. © 2012 IEEE.
