description Publicationkeyboard_double_arrow_right Conference object , Article 2013 FrancePublisher:Informa UK Limited Authors: Allouche, A.; Nicolas, L.; Tourment, R.;Allouche, A.; Nicolas, L.; Tourment, R.;doi: 10.1051/lhb/2013034
Cette communication présente un modèle d’évaluation de la vulnérabilité sociale au risque inondation dans les zones protégées par des digues. Ce modèle articule trois échelles d’analyse. Une échelle macrosociologique porte sur les tendances économiques et socio-démographiques afin d’évaluer la vulnérabilité de grandes unités territoriales cohérentes. L’échelle mésoscopique fait référence à l’espace de groupes sociaux et de regroupements humains cohérents. A cette échelle, on privilégie le recours à l’enquête par questionnaires auprès de ménages en zone inondable. La méthodologie proposée s’oriente en particulier vers une approche comportementaliste afin d’évaluer la propension des individus à s’exposer au risque, en fonction également de leurs capacités d’adaptation, de leurs connaissances de l’inondation, des actions préventives adoptées par les ménages, etc. Enfin, à l’échelle microsociologique, au moyen d’entretiens semi-directifs, l’approche développée tente de cerner les conditions et restrictions à la mise en oeuvre de méthodes quantitatives pour l’évaluation de la vulnérabilité sociale. Toward a socio-anthropological approach for assessing the social vulnerability of areas protected by the Rhone river dams. A three-scaled model is assumed to estimate the social vulnerability of leveed areas. A macro scale refers to the economic and socio-demographic trends that allow to assess the vulnerability of coherent large urban areas. A meso scale refers to homogenous communities or social groups. At this scale, the assessment of vulnerability proceeds by questionnaire surveys of households in flood risk areas. The methodology especially adopts a behavioral approach trying to estimate the propensity of people to self-exposure to risks, risk-taking practices, adaptive capacities, knowledge of flood process, the mitigation actions undertaken by householders, etc. At a micro scale, thanks to semi-structured interviews the methodology tries to assess the conditions and the restrictions to an assessment of vulnerability by means of quantitative methods.

The traditional ways of modeling generally have common problems such as low efficiency, waste of manpower and time consumption. How to find a rapid approach to automatically complete large-scale 3D modeling is a very hot research topic. In this paper we propose a novel approach of procedural modeling of buildings with CityEngine, which is combined with ArcGIS technology for the geographic information. This approach produces extensive architectural 3D models with high visual quality and geometric details at low cost. It includes following two contents concretely. At first, directly writing computer generated architecture (CGA) shape grammar to complete procedural modeling of building and other objects. Secondly, using facade modeling based on two-dimensional images to generate architectural model as well as creating high geometry details. It is validated that this novel approach of procedural modeling is a significant step forward that reduces a lot of modeling times by CGA shape grammars.

There are 61.84% of rural residents who once conducted online shopping, but there are only 32.89% of rural residents having tried to sell or market their own agricultural products on the internet. Econometric model is used to find out the factors influencing rural residents to choose E-commerce. Rural residents with younger age are more willing to launch agricultural business through e-business, rural residents with higher annual income are more willing to attempt; and the ones with experiences of e-commerce online shopping are more willing to accept e-commerce of agricultural products. These suggestions are to provide with more trial opportunities and to provide rural residents with more training opportunities.

Traditionally, the region was poor with an agricultural oriented economy. However, by the 1960s a new type of business was launched: the residential care facilities for disabled people, especially in relation to Jacques Blanc, a key person in the organization and development of this business. This economic activity brought jobs and new attractiveness, counterbalancing decline in traditional sectors. Nevertheless, currently, situation is less favourable, and the local players try to find out a new strategy, particularly in relation to diversification. In this study, our main aim was to understand conditions of starting and growing of this business. Moreover, we would like to understand current fragilities and attempts to adapt the economy of the territory. In this way, our students and we have chosen this area in relation to the economic and historical weight of its activity. The organization of field trips and survey was conducted in a comprehensive approach perspective. Therefore, we took account parameters working in this territory, such as strategies, psychologies (individual and collective), networks and identities. Human dimensions are strong, especially in discourses, and our main result is a better understanding of the local situation, with comparisons to close cases (Corrèze, Creuse). Furthermore, the quality of the geographical analysis provides working relations with the stakeholders

It aims to highlight the different factors of the adoption of these digital technologies in agriculture. The theoretical framework of the research is based on two well-known models of adoption of new technologies (TAM and TOE). The authors propose a model combining the previous two. A bibliometric analysis of several articles dealing with digital adoption in agriculture was then conducted. It allows to refine the proposed model, by selecting the most relevant variables.

In fact, deploying a fleet of Unmanned Aerial Vehicles (UAVs) and using them to take environmental samples is an approach that has the potential to become one of the key enabling technologies to enforce pollution control in industrial or rural areas. In this paper, we propose to use an algorithm called Pollution-driven UAV Control (PdUC) that is based on a chemotaxis metaheuristic and a Particle Swarm Optimization (PSO) scheme that only uses local information. Our approach will be used by a monitoring Unmanned Aerial Vehicle to swiftly cover an area and map the distribution of its aerial pollution. We show that, when using PdUC, an implicit priority is applied in the construction of pollution maps, by focusing on areas where the pollutants' concentration is higher. In this way, accurate maps can be constructed in a faster manner when compared to other strategies. We compare PdUC against various standard mobility models through simulation, showing that our protocol achieves better performances, by finding the most polluted areas with more accuracy, within the time bounds defined by the UAV flight time.

To handle the ambiguities arising in this scenario, a common strategy is, first, to generate multiple estimates for the camera pose from which a given query image was taken. The pose with the largest geometric consistency with the query image, e.g., in the form of an inlier count, is then selected in a second stage. While a significant amount of research has concentrated on the first stage, there is considerably less work on the second stage. In this paper, we thus focus on pose verification. We show that combining different modalities, namely appearance, geometry, and semantics, considerably boosts pose verification and consequently pose accuracy. We develop multiple hand-crafted as well as a trainable approach to join into the geometric-semantic verification and show significant improvements over state-of-the-art on a very challenging indoor dataset.

Usually the pixel size is larger than the typical size of material change over planets, leading to a linear spatial mixing. We propose here an unsupervised approach based on source separation methods to estimate the pure spectra of the components present in the observed scene and their abundances in each pixel. Previous studies have shown that this approach is interesting for Martian ices. This method assumes the positivity of both the pure spectra and the mixing coefficients. We propose here to apply this technique to detect Martian minerals and we show that adding the sum-to-one constraint (or additivity constraint) on the abundance vectors allows one to improve the estimation performance.

Cette communication présente un modèle d’évaluation de la vulnérabilité sociale au risque inondation dans les zones protégées par des digues. Ce modèle articule trois échelles d’analyse. Une échelle macrosociologique porte sur les tendances économiques et socio-démographiques afin d’évaluer la vulnérabilité de grandes unités territoriales cohérentes. L’échelle mésoscopique fait référence à l’espace de groupes sociaux et de regroupements humains cohérents. A cette échelle, on privilégie le recours à l’enquête par questionnaires auprès de ménages en zone inondable. La méthodologie proposée s’oriente en particulier vers une approche comportementaliste afin d’évaluer la propension des individus à s’exposer au risque, en fonction également de leurs capacités d’adaptation, de leurs connaissances de l’inondation, des actions préventives adoptées par les ménages, etc. Enfin, à l’échelle microsociologique, au moyen d’entretiens semi-directifs, l’approche développée tente de cerner les conditions et restrictions à la mise en oeuvre de méthodes quantitatives pour l’évaluation de la vulnérabilité sociale. Toward a socio-anthropological approach for assessing the social vulnerability of areas protected by the Rhone river dams. A three-scaled model is assumed to estimate the social vulnerability of leveed areas. A macro scale refers to the economic and socio-demographic trends that allow to assess the vulnerability of coherent large urban areas. A meso scale refers to homogenous communities or social groups. At this scale, the assessment of vulnerability proceeds by questionnaire surveys of households in flood risk areas. The methodology especially adopts a behavioral approach trying to estimate the propensity of people to self-exposure to risks, risk-taking practices, adaptive capacities, knowledge of flood process, the mitigation actions undertaken by householders, etc. At a micro scale, thanks to semi-structured interviews the methodology tries to assess the conditions and the restrictions to an assessment of vulnerability by means of quantitative methods.

The traditional ways of modeling generally have common problems such as low efficiency, waste of manpower and time consumption. How to find a rapid approach to automatically complete large-scale 3D modeling is a very hot research topic. In this paper we propose a novel approach of procedural modeling of buildings with CityEngine, which is combined with ArcGIS technology for the geographic information. This approach produces extensive architectural 3D models with high visual quality and geometric details at low cost. It includes following two contents concretely. At first, directly writing computer generated architecture (CGA) shape grammar to complete procedural modeling of building and other objects. Secondly, using facade modeling based on two-dimensional images to generate architectural model as well as creating high geometry details. It is validated that this novel approach of procedural modeling is a significant step forward that reduces a lot of modeling times by CGA shape grammars.

There are 61.84% of rural residents who once conducted online shopping, but there are only 32.89% of rural residents having tried to sell or market their own agricultural products on the internet. Econometric model is used to find out the factors influencing rural residents to choose E-commerce. Rural residents with younger age are more willing to launch agricultural business through e-business, rural residents with higher annual income are more willing to attempt; and the ones with experiences of e-commerce online shopping are more willing to accept e-commerce of agricultural products. These suggestions are to provide with more trial opportunities and to provide rural residents with more training opportunities.

Traditionally, the region was poor with an agricultural oriented economy. However, by the 1960s a new type of business was launched: the residential care facilities for disabled people, especially in relation to Jacques Blanc, a key person in the organization and development of this business. This economic activity brought jobs and new attractiveness, counterbalancing decline in traditional sectors. Nevertheless, currently, situation is less favourable, and the local players try to find out a new strategy, particularly in relation to diversification. In this study, our main aim was to understand conditions of starting and growing of this business. Moreover, we would like to understand current fragilities and attempts to adapt the economy of the territory. In this way, our students and we have chosen this area in relation to the economic and historical weight of its activity. The organization of field trips and survey was conducted in a comprehensive approach perspective. Therefore, we took account parameters working in this territory, such as strategies, psychologies (individual and collective), networks and identities. Human dimensions are strong, especially in discourses, and our main result is a better understanding of the local situation, with comparisons to close cases (Corrèze, Creuse). Furthermore, the quality of the geographical analysis provides working relations with the stakeholders

It aims to highlight the different factors of the adoption of these digital technologies in agriculture. The theoretical framework of the research is based on two well-known models of adoption of new technologies (TAM and TOE). The authors propose a model combining the previous two. A bibliometric analysis of several articles dealing with digital adoption in agriculture was then conducted. It allows to refine the proposed model, by selecting the most relevant variables.

In fact, deploying a fleet of Unmanned Aerial Vehicles (UAVs) and using them to take environmental samples is an approach that has the potential to become one of the key enabling technologies to enforce pollution control in industrial or rural areas. In this paper, we propose to use an algorithm called Pollution-driven UAV Control (PdUC) that is based on a chemotaxis metaheuristic and a Particle Swarm Optimization (PSO) scheme that only uses local information. Our approach will be used by a monitoring Unmanned Aerial Vehicle to swiftly cover an area and map the distribution of its aerial pollution. We show that, when using PdUC, an implicit priority is applied in the construction of pollution maps, by focusing on areas where the pollutants' concentration is higher. In this way, accurate maps can be constructed in a faster manner when compared to other strategies. We compare PdUC against various standard mobility models through simulation, showing that our protocol achieves better performances, by finding the most polluted areas with more accuracy, within the time bounds defined by the UAV flight time.

To handle the ambiguities arising in this scenario, a common strategy is, first, to generate multiple estimates for the camera pose from which a given query image was taken. The pose with the largest geometric consistency with the query image, e.g., in the form of an inlier count, is then selected in a second stage. While a significant amount of research has concentrated on the first stage, there is considerably less work on the second stage. In this paper, we thus focus on pose verification. We show that combining different modalities, namely appearance, geometry, and semantics, considerably boosts pose verification and consequently pose accuracy. We develop multiple hand-crafted as well as a trainable approach to join into the geometric-semantic verification and show significant improvements over state-of-the-art on a very challenging indoor dataset.

Usually the pixel size is larger than the typical size of material change over planets, leading to a linear spatial mixing. We propose here an unsupervised approach based on source separation methods to estimate the pure spectra of the components present in the observed scene and their abundances in each pixel. Previous studies have shown that this approach is interesting for Martian ices. This method assumes the positivity of both the pure spectra and the mixing coefficients. We propose here to apply this technique to detect Martian minerals and we show that adding the sum-to-one constraint (or additivity constraint) on the abundance vectors allows one to improve the estimation performance.
