Applying system dynamics modeling to foster a cause-and-effect perspective in dealing with behavioral distortions associated with a city's performanc…
2015
This paper aims to show how applying system dynamics methodology to performance management can provide a powerful modeling perspective enabling public sector organizations to prevent, detect, and counteract behavioral distortions associated with performance measurement. A dynamic performance management approach is able to support performance management system designers in outlining and implementing a consistent set of measures that can allow public sector decision-makers to pursue sustainable organizational learning and development. This perspective implies a major shift from a static to a dynamic picture of organizational processes and results. It means framing delays between causes and ef…
Contributions to the physical and experimental validation of a simultaneous PET/MRI system dedicated to small animal imaging
2020
Simultaneous PET/MRI is a dynamic research field of both medical and preclinical domains. The ability of integrated systems to acquire the highly complementarity MR morphological and PET functional data in a single examination paves the way to innovative applications. The hereby document presents a series of experimentations dealing with the performance evaluation and the experimental in vivo capacities of such a device. Physical measurements were implemented based on international standards or inspired by articles of reference. The evaluated system consists of a compact SiPM-based PET subsystem fully integrated in a 7 T preclinical MRI based on the dry magnet technology. Experimentations s…

Exploring the high-pressure behavior of the three known polymorphs of BiPO4: Discovery of a new polymorph
2015
We have studied the structural behavior of bismuth phosphate under compression. We performed x-ray powder diffraction measurements up to 31.5 GPa and ab initio calculations. Experiments were carried out on different polymorphs: trigonal (phase I) and monoclinic (phases II and III). Phases I and III, at low pressure (P < 0.2-0.8 GPa), transform into phase II, which has a monazite-type structure. At room temperature, this polymorph is stable up to 31.5 GPa. Calculations support these findings and predict the occurrence of an additional transition from the monoclinic monazite-type to a tetragonal scheelite-type structure (phase IV). This transition was experimentally found after the simultaneo…
The pianists in front of Liszt's Sonata in B minor
2015
Our research focuses a comparative analysis of the performances of Liszt's Sonata in b minor. We analysed twenty-five recordings by pianists grouped into five piano schools : Hungarian, French, Russian, American and German. We compared the deviations of the performers from the score and the differences between the individual performances, based on a selection of seven parameters that allowed us to characterise each of them. A double analysis was made: "by ear" and with the aid of acomputer. Our research has shown the importance of several complementary factors of influence : education, the period during which the pianists lived and created, the artists' temperaments and their artistic indiv…
Towards the Environmental Sustainability of the Construction Sector: Life Cycle Environmental Impacts of Buildings Retrofit
2022
In the context of the need for carbon emissions reduction, the buildingsector, as one of the most energy intensive one, needs tools and approaches towards carbon neutrality and the increase of the buildings overall energy performances. The paper proposes an integrated approach towards the environmental performances analysis of a small neighborhood having as goal the achievement of the Positive Energy District target and the assessment of its environmental impacts. The methodology proposed includes building modeling and dynamic energy simulation using the Energy Plus engine and a simplified Life Cycle Assessment approach. Two scenarios are investigated: i) the existing neighborhood, ii) the …

Bus Speed Estimation By Neural Networks To Improve The Automatic Fleet Management
2007
In the urban areas, public transport service interacts with the private mobility. Moreover, on each link of the urban public transport network, the bus speed is affected by a high variability over time. It depends on the congestion level and the presence of bus way or no. The scheduling reliability of the public transport service is crucial to increase attractiveness against private car use. A comparison between a Radial Basis Function network (RBF) and Multi layer Merceptron (MLP) was carried out to estimate the average speed, analysing the dynamic bus location data achieved by an AVMS (Automatic Vehicle Monitoring System). Collected data concern bus location, geometrical parameters and tr…
Toward a European Eco-label brand for residential buildings: Holistic or by-components approaches?
2011
The Eco-label scheme is becoming ever more important in the environmental certification of products and services, especially in light of the recent ambitious aim of containing greenhouse emissions and improving the efficiency of utilizing energy sources. A recently-introduced hypothesis concerns the European Eco-label scheme relating to buildings, in the awareness that the construction industry is of primary importance to the whole economic and social life of states. This scheme should adopt an integrated approach to environmental problems and include construction, day-to-day management, and the possible disposal of building materials, throughout the life cycle of the building. In addition,…
