We propose a new algorithm for generating quickly approximate generalized Voronoi diagrams of point sites associated to arbitrary convex distance metric in the Euclidian plane. This algorithm produces connected cells by emulating the growth of crystals starting at the point sites, in order to reduce the complexity of the diagram. The main practical contribution is the Vorosweep package which is the reference implementation of the algorithm. Experimental results and benchmarks are given to demonstrate the versatility of this approach. [less ▲]

In this paper, the problem of integrating photo- voltaic panels into low-voltage distribution networks is addressed. A distributed scheme is proposed that modulates the active and reactive power output of inverters to prevent overvoltage problems. The proposed scheme is model-free and makes use of limited communication between the controllers, in the form of a distress signal, only during emergency conditions. It prioritizes the use or reactive power, while active power curtailment is performed only as a last resort. The performance of the scheme is tested using dynamic simulations, first on a single low-voltage feeder, then on a larger network composed of 14 low-voltage feeders. Its performance is compared to a centralized scheme based on the solution of an Optimal Power Flow problem, whose objective function is to minimize the active power curtailment. The proposed scheme successfully mitigates overvoltage situations due to high photovoltaic penetration and performs almost as well as the Optimal Power Flow based solution with significantly less information and communication requirements.

In China, some areas with intensive agricultural use are facing serious environmental problems caused by non-point source pollution (NPSP) as a consequence of soil erosion (SE). Until now, simultaneous monitoring of both NPSP and SE is difficult due to the intertwined effects of differences in crop type, topography and management in these areas. Based on meteorological data, a Geographic Information System (GIS) database and soil and water samples, we propose a new integrated method to monitor SE and NPSP simultaneously and apply to an intensive agricultural area (Nanjing area, ~6 000 km2) in eastern China. The results showed that the levels of soil total nitrogen (TN), total phosphorus (TP), ammonium nitrogen (AN) and available phosphorus (AP) can be used to assess and predict the extent of NPSP and SE status in the study area. Most SE and the greatest NPSP loads occurred between April to August. The most seriously affected area in terms of SE and NPSP was the Jiangning District, implying that the effective management of SE and NPSP in this area should be considered a priority. The sub-regions with higher vegetation coverage contributed to less SE and NPSP, affirming the conclusions of previous studies, namely that vegetation is an effective factor in controlling SE and NPSP. This study shows that the application of our quantitative method has both high precision and reliability for the simultaneous monitoring of SE and NPSP occurring in intensive agricultural areas.

Le concept de « flexicurité » est un oxymore prônant un équilibre « Win-Win » entre flexibilité et sécurité sur le marché du travail. Cet équilibre est-il possible ? Son caractère antinomique ne génère-t-il pas de la contradiction dans le discours des acteurs ? C’est ce que nous allons tenter de découvrir dans cet article, au travers de l’étude du processus discursif de travailleurs, interrogés sur leurs représentations respectives de la flexibilité et de la sécurité dans leurs pratiques professionnelles. Cette étude est le résultat de regards croisés entre trois disciplines – psychologie, gestion et sociologie – et de l’utilisation d’un logiciel d’analyse qualitative : « Cassandre » (Lejeune, 2008). L’objectif de cet article est d’une part, d’explorer la pertinence du recours à un logiciel dans le cadre d’un travail de recherche collaboratif interdisciplinaire et, d’autre part, de créer une revue de littérature transversale aux trois disciplines.
